As the part of the research on functional addition of our sheet for applying paper prevention, the extension of the sign display function (visibility) was examined. The applying paper prevention sheet stopped illegal applying papers, and it contributed to the maintenance of the landscape. This sheet was developed as functional sheet (the sign sheet) with the information notice function. The material of our sheet was mainly the generality plastic, and the use endurance years in outdoor was a long term. However, it was required that the visibility of the information notice was retained, when information was shown at this sing sheet for the period equal to the use endurance years of an applying paper prevention sheet. As a notice method of information, the weather resistance of the outdoor use was considered, and it was appropriate to carry out the direct printing to an applying paper prevention sheet. It is optimum to carry out the ink jet printing which was correspondent to not uniform large scale printing but multi-itemed little scale printing. In this paper, the authors report research result following; weather resistance (ultraviolet ray-proof and rainfall-proof) or physical strength (antifriction, peeling-proof, skid-proof capacity) of printing visibility in the outdoor use of the sign sheet of ink jet printing for our applying paper prevention sheet. In addition, the application for the floor material is also reported, because the progressive experience of skid-proof capacity floor material was examined.

The formation process of kaolinitc in the hydrothermal reaction of an amorphous calcium silicate with aluminum chloride was studied by XRD, IR, DTA-TG, TEM, and high-resolution solid state ²⁹Si-MAS/NMR. The amorphous calcium silicate prepared from diatomite and calcium hydroxide was hydrothermally treated with an aluminum chloride solution in a Teflon pressure vessel at 220°C for a reaction period varying from 1 to 144 h. As the first step of the reaction, the Q² state component of the starting material changed into an intcrmcdiate amorphous with the Q³ state. The degree of silica-polycondensation of this state is identical to that of the intermedicate phase observed in the kaolinitization from the amorphous mixture of silica and alumina. The intermediate amorphous phase was then converted directly into the crystalline kaolinite with a platy shape (the Q³ state), without forming a spherical kaolinite. The latter was observed in the reaction system started from an amorphous mixture of silica and alumina.

When a vehicle runs, the vibration that a road surface causes brings about discomfort of the driver and consumption of the surplus fuel. When a road surface state is bad, it is necessary to detect the irregularity of the road surface. For example, they photograph the dispersion dynamic scattering pattern that inspection light was scattered in on a road surface with a camera and detects having irregularity or not of the road surface and detects the irregularity by a millimeter wave sensor. However, they judge only an irregularity and does not think about the influence on body. In this study, we measure run data and detect the irregularity of the road surface.

Asymmetric syntheses of optically active abscisic acid and xanthoxin have been performed conveniently by an asymmetric induction method. Sharpless oxidation of cyclohexene methanol derivative(3), which was easily available by known method, and following Swern oxidation gave an asymmetric epoxy-aldehyde intermediate(6). Propagation of a side chain by Reformatsky reaction at the aldehyde group, followed by dehydration of the adduct with alkoxide, resulted in a stereospecific introduction of the side chain to obtain a key diene-intermediate(10). Transformation into optically active abscisic acid was performed simply in one step by treatment of 10 with hydrochloric acid. Acid treatment of the intermediate(10) under more mild condition resulted in selective removal of cyclic acetal to form keto-epoxide(12). Stereospecific reduction of the ring-calbonyl group with K-Selectride gave a β-hydroxy derivative(14β) preferentially. Conversion of the terminal ester group in 14β to aldehyde via LAH reduction followed by MnO_2 oxidation gave optically active xanthoxin successfully.

The thallation-halogenation method shown in the equations, (1) and (2), was successfully applied for a regioselective and common synthetic method for indoles carrying two different kinds of halogens and consequently 4,5-, 4,6- and 4,7-dihalogenoindole-3-carboxaldehydes (13, 16 and 18) were prepared from 5-, 6- and 7-halogenoindole-3-carboxaldehydes (11, 15 and 17), respectively. Indoles having 5,7- and 6,7-dihalogens (21 and 22) were also prepared from N-acetyl-5- and 6-halogenoindolines (12 and 14), respectively. Thus, regioselective and reliable synthetic method for every dihalogenated type indoles is established. Direct bromination of methyl 4- and 7-halogenoindole-3-carboxylates (24 and 27) was found to afford regioselectively 4,5-, 4,7- and 6,7-dihalogenated type indoles (25, 26 and 28). Their structures were unequivocally proved by the direct comparisons with the authentic samples prepared from the compounds (13, 18b and 22) by means of the thallation-halogenation method. Marine indolealkaloids, 4,6-dibromo- and 3,4,6-tribromoindoles (1a and 1c) were synthesized from 4,6-dibromoindole-3-carboxaldehyde (16) prepared by the thallation-halogenation method. The first total synthesis of 4,6-dibromo-2-methylindole (1b) is achieved as shown in the Scheme 3. A synthetic approch to 4,5,6-tribromoindole (33) from N-acetyl-5-aminoindoline (34) is also reported.

The purpose of Patent Law is, through promoting the protection and the utilization of inventions, to encourage inventions, and thereby to contribute to the development of industry. Thus, the concept of the Patent Law affects the promotion of the future innovation, and then, revision of the Patent Law attracts attention in recent years. On July 10, this year, revised Patent Law was promulgated, and provisions about the employee's invention were revised. Under the current system, the patent rights (the rights to obtain patents) of inventions invented in companies belong to inventors, and transferred to corporations. After this Patent Law revision, the patent rights (the rights to obtain patents) belong to corporations from the beginning. With introduction of this revised employee's invention system, the consideration that does not obstruct incentive to invention will be necessary in future.

In order to elucidate the faunal characteristics of a brackish lake, Kamo-ko, located in Sado Island in the Japan Sea, a biological survey was carried out during these several years. This lake, 4.86km2 in area, 17.2km in circumference, and 8.7m in the greatest depth, is famous and active for oyster cultivation, and its mouth communicates with Port Ryotsu, i. e., Ryotsu Bay, by a narrow channel, 200m long and 28m wide. Physico-chemical analyses and limnological observations including paleo-liinnological investigations using 18 m core-sample of the bottom were undertaken to know the environmental conditions of the lake. In all ca. 160 species of animals including ca. 50 species of teleost fishes collected up to the present were listed in this paper. All animals, except one leptostracan Crustacea (Nebalia bipes), were of common occurrence in the coasts of Sado Island, however. It is the first characteristic of the faunal elements of Lake Kamo-ko that the tunicates (Ciona intestinalis, Ascidia zara and Botrylloides violaccus), sponge (Ilaliclona permollis) and bivalve mollusk (Mytilus edulis) are dominant species attached to the bamboo-made rafts and the strings suspended from the rafts for oyster cultivation. The bryozoans (JB-ugula neritina and Caulibugula clliata) are also abundant in this lake. The bottom consisting of sand and sandy mud is very narrow and is confined to the marginal zone of the lake. The eel grass (Zostera marina and Z. nana) and other rooted plants flourish in this zone. Most of the bottom covered deeply with a sedimentation of the black mud is devoid of oxygen, seaweeds and benthic fishes. But, even in this worse environment, there are found some polychaetous annelids (Lumbrincris brevicirra, Cirriformia tentaculata and Capitella capitatci) and bivalve mollusk (Musculus senhousia and Modiolus agripetus) which are able to tolerate water pollution. The paucity of organism on the bottom is the second characteristic of the fauna of this lake. The third point is exhibited by the rapid propagation of the recently immigrated barnacles (Balanus eburneus and B. improvisus) insted of other foreign barnacles (73. amphitrite and B. albicostatus). To obtain much more information, further investigations are now in going progress.

Most grabs of ordinary design have several disadvantages such as : 1. The course traversed by the grab is complex, 2. Handles and handlings are too numerous, 3. A large grab, therefore, is to be used in order to increase the capacity of the machine, 4. The larger the grab, the greater will be the power of the prime mover, 5. Owing to the jerk and vibration of ropes by which the grab is suspended, it is practically impossible to grab the material at an exact desired point within the scope, 6. Twisting and entangling of ropes have the effect to decrease the capacity of the machine and the life of the ropes, 7. There is a risk of over-winding of ropes on the top guide pulley, 8. It is necessary to gather and scavenge the remaining material after grabbing, 9. The position of the operator's cage is too high to have a good command of view of the material to handle, 10. It is very difficult to weigh the content of grab, 11. The automatic operation of the machine is impossible. In order to overcome all the defects mentioned above, I have deviced a new system, which I claim to be a novel one in its own way. The system is a combination of a grab and a conveyer, in which the grab moves in a vertical direction. A swinging chute which stands vertically by means of a counter-weight connected to it, is placed in the midway of the passage of the grab. When the grab handles material, and is lifted vertically up to a suitable position, the upper part of the grab lifts the counter-weight, and so the chute projects itself to the passage of the grab. After discharging its content, the grab is lowered accompanying the counter-weight of the chute, and the chute recovers its upright position making a free passage to the grab. The system further involves the guide-bars with operator's cage and scraping boards at their lower ends, for the vertical passage of the grab. The guide-bars themselves are also guided by a fixed frame, and are operated vertically by an operator according to the position of the material to be handled. In my machine I reduced the number of handles and handlings to an extreme limit, i.e. only to one, and thus succeeding to turn out a maching of an automatic operation which is almost impossible in all the machines of the similar nature now in use. Further-more the capacity of the machine is increased three to seven times the ordinary one with the same size of grab, and five to twelve times with the same power of the motor by which the grab is operated, leaving the weighing and the conveying to the conveyor combined to the system, which consumes only a small fraction of power required for the grab.

海に囲まれた火山島では観測できる場所が限られ,火山灰の堆積量を推定することが困難であった.また,火山灰が大量に降ることによって交通,健康,農作物へ影響を生じ,厚く堆積した斜面では土石流が発生しやすくなる.ゆえに火山灰の降下量(降灰量)や分布を迅速に把握する方法の開発は,火山学,防災学上の重要な研究対象となる.このため桜島のように海に囲まれ観測場所が限られる火山での迅速かつより少ない点から火山灰の堆積分布・量を推定する方法を検討した.我々は等層厚線が相似の楕円に近似されると仮定し,各点から得られる楕円近似した等層厚線の軸比を一定とし,分布を幾何学的に単純化した.また,降灰観測データの豊富な噴火事例を検証した結果,面積=層厚がA=αT^d(T:層厚,A:面積)とした場合,その減衰はほぼ-1乗に近似可能である.これらの関係より,火口位置などを楕円の軸端点とし,火山灰堆積分布に相当する分布軸が決められる場合,計算上2点の観測値から火山灰堆積量を推定することが可能となる.ただし,本手法では通常,計算軸を求める際に,計算に使用する2点以外の1～4点程度の複数観測点の値が必要となる.本手法については分布軸が精度良く求められることと,複数の観測値を解析結果が矛盾なく説明できることを適応条件とした.本手法を用い桜島2008年の活動について60を超える噴火の火山灰堆積量を推定した.推定した分布から特定の場所における月ごとの累積降灰量を計算した結果は観測量を再現可能である.2008年の桜島の活動を日単位の堆積量として解析すると,ピークは5月6～23日頃であったと推定される.本方法を適応することによって,これまで観測が難しかった火山島での火山灰堆積量観測が可能となる.
