ジャーナル フリーThis paper describs the recent and future trends of image and information technology which were viewed from points of the printing technics of newspaper, technical revolution of printing systems and new technical trends of image transfer system containing reprographic hardware.
1. Role of newspaper as mass communication media has been shifted to another processes such as radio or television.
2. Reproduction technology from information to imaging in newspaper has been rapidly transfered to Computerized Type-setting System (CTS).
3. New information propagating service systems to homelife, education, amusement and social informations etc, has been developed in mordern life society.
4. It is setimated that the reprographic technology futher advances in future, especially, application of heat sensitive paper for home facsimile copia fields shall increase to another reprographic papers.抄録全体を表示PDF形式でダウンロード (867K) -

ジャーナル フリー情報産業用紙は印刷用紙, 段ボール原紙などと相違して, 紙の品種分類の名称ではなくて, 情報の入出力媒体として用いられる紙の総称である。
現在この分野で使われている紙の大部分は, 各種の情報の入出力システムのニーズに対応して開発されたものが多い。
一般にいわれている情報産業は情報の生産から流通までのプロセスに関与するすべての産業群を包含する非常に幅の広いものであるが, その中から, 事務複写, コンピュータ, 画像通信に使われる入出力媒体が中心となる。抄録全体を表示PDF形式でダウンロード (980K) -

ジャーナル フリーFuji City, located at the foot of Mount Fuji, has been famous for paper manufacturing since ancient days and now more than 100 paper mills are in operation there.
Honshu Paper Co., Ltd.'s Fuji Mill, located in the west part of Fuji City, started its operation in 1908.
The mill has 6 paperboard machines (4 cylinder machines, 2 combination machines), 3 paper machines (2 Fourdrinier machines, 1 vertiformer machine), and 1 coater. Its products are 528 tons per day of coated board, 239 tons per day of printing paper and 159 tons per day of coated paper.
The mill has waste paper equipment instead of pulping equipment such as KP, TMP or CGP.
The mill has an area of 600, 000 m2, which not only contains the paper machine and equipment mentioned above, but also a pulp molding plant, a paperboard converting plant and an ironworks in the same area. There are about 1, 100 employees.
The waste water from the mill is treated with an activated sludge process, 4 clarifiers and sludge incineration equipment.抄録全体を表示PDF形式でダウンロード (17156K) -

ジャーナル フリーThe relationships between tensile properties and the bonded area of paper were studied by correlation analysis and graphically represented.
The squares of tensile strength and breaking length or tensile energy absorption are highly correlated with the bonded area of paper.
The regression lines, represented graphically, almost showed linear relations. By introducing the survey of rupture energy into the analysis of mechanical properties of paper, it was found that, in many cases, linear relations exist between the rupture energies and bonding areas of paper.抄録全体を表示PDF形式でダウンロード (929K) -

ジャーナル フリーSome eucalyptus species from Western Australia contain high amount of polyphenols to give a lower pulp yield by alkaline cooking. H. G. Higgins has suggested that destruction of chips by passing between two rolls of different peripherical speeds improves pulping.
This study has been carried out to improve pulp yields and delignification of chips from above species. Mill chips of E. marginata, mixture of E. calophylla and E. diversicolor and mixture of domestic hardwood species were destructured passing through two rolls of 8″ diameter, of which rotation were 24.8 and 32.2 rpm respectively at clearance of 1.6, 1.3, 1.0 and 0.7 mm. Bulk density of treated chips were increased about 10 to 25%.
It was obiously observed that screened yields of sulphate pulps at the same Kappa number were improved by destruction treatment. As far as pulp strengths, over-destructured chips by 0.7 mm clearance of rolls showed some damages due to reduction of fibre length. However, strengths of handsheets seemed not so lowered in case of some moderate roll clearances.
Destruction treatments induced fissures in chips, however, the pore or void volume in chips measured by the mercury penetration revealed that chips were significantly densified. Further investigations are to be needed.抄録全体を表示PDF形式でダウンロード (1351K) -
