      The influence of residual gases in an rf sputtering chamber on the magnetic proprties of Co sputtered films is investigated by nuclear magnetic resonance of 59Co nuclei. The surfaces of the prepared Co sputtered films are oxidized. In the films the nitrogen gas is combined with Co atoms and forms the Co4N phase. The broad line width of resonance signals and the slow decrease of signal intensity with the external magnetic fileld suggest that the Co oxides and the Co4N have large effects on the structure of magnetic domains and walls. Under the different gas-flow conditions, the formation of the Co4N phase and the structural change of Co from the hcp phase into the fcc phase can be observed by the apperance of satellite lines and the shift of the main line of spin echo spectra. It is found that the nuclear magnetic resonance is a powerful means for the study of magnetic properties and phase change on the Co sputtered films.

      The temperature dependence of the anisotropy field and anisotropy constants of Sm2Fe17N3 was evaluated from the calculated magnetization curves, using crystal field parameters obtained in a previous study. The anisotropy field of Sm2Fe17N3 at 0 K was estimated to be 750 kOe; this estimate was confirmed by pulsed-field magnetization measurements up to 1100 kOe. The coercivity of Sm2Fe17N3 magnets was found to be strongly influenced by the maximum applied field. This fact indicates that the coercivity of Sm2Fe17N3 magnets is nucleation-controlled. The coercivity of Sm2Fe17N3 magnets increased monotonically with decreasing temperature, except in the case of a zinc-bonded magnet (30 wt% Zn). The relationship between the coercivity and the magnetocrystalline anisotropy of Sm2Fe17N3 is discussed.

    Minerals of Ni-S, Fe-S and Fe-Ni-S systems were investigated by Geiger counter X-ray spectrometer in order to clarify the mineral composition of crude nickel matte produced by fusion of garnielite, gypsum and limestone with coke.
    In Ni-S system the compound Ni3S2 and NiS, and in Fe-S system the compound FeS were formed as sulphides. In Fe-Ni-S system a compound pentlandite was formed in the range of 4.5 Fe.4.5Ni·8.9-5Fe·4Ni·8S. When the product contained much more Fe component, FeS was formed together with pentlandite and Ni·Fe solid solution. When the nickel content of the product was much more than the above range, Ni3S2, pentlandite and nickel rich Ni·Fe solid solution were formed.
    It was clarified that the crude nickel matte containing 58-% of Fe, 22% of Ni and 18% of S consisted of FeS, nikel rich Ni·Fe solid solution and small amount of pentlandite. The matte containing 62% of Fe, 21% of Ni and 15% of S was composed of FeS and Ni·Fe solid solution.

    From our study on the 13 codices of NHTs, which was being published from 1956 to 1963, we have come to the following conclusions.
    1. Concerning the characteristics of the Gnosticism the NHTs reconfirm the results which had been drawn from the other Gnostic materials: (1) the knowledge on the “consubstantiality” between one's self and the supreme Godhead, (2) the substantial dualism and (3) the revelation of the Godhead (=one's self) through a Revealer or Redeemer. But the heresiologists of the “Great Church” have denounced form their point of view the points (2) and (3) so emphatically that the point (1) does not come enough into their sight. We can find neither “typical” Gnostic, speculative myths (2) nor so-called “Docetic” Christology (3), at least in the “Gospels” of the NHTs. On the contrary our texts are all founded on the “gnosis” of the consubstantiality (1).
    2. By the light of the NHTs it becomes clearer that the Gnosticism originated in the borderlands between Judaism (including Diaspola) and other hellenistic religions, for example in Samalia, Syria and Egypt, for the most of the NHTs depend on the Gnostic interpretation of the Judaic materials.
    3. Can we attest any conception of so-called “pre-Christian” Gnostic redeemer? To answer such a question is of course impossible, as the publication of the whole NHTs is not yet completed. We are inclined to think, however, that it is not from Christianity that Gnosticism borrowed the idea of its redeemer, for we can demonstrate by the textual criticism that such a redeemer as “Sophia” is more original than “Christ” in the Apocryphon Johannis and other NHTs.
    4. NHTs make it clearer that such rituals as baptism and chrism play the important role to combine Gnosticism with Christianity, especially “Sophia” with “Christ”.

      High purity (more than 4N) nitrogen gas can be used as a substitute gas for argon gas (5N) in molten aluminum treatment. The effects of nitrogen gas purity on molten aluminum treatment were clarified in this study.

      AC8A (modified) alloy, four kinds of nitrogen gases (2N, 3N, 4N and 5N), and argon gas (5N) were prepared.

      Equivalent removal of inclusion and fluidity were seen after molten aluminum treatment by each gas.

      In comparison to 5N argon gas, the 5N and 4N nitrogen gases had equivalent degassing ability. In applying the nitrogen gas to molten aluminum treatment, above 4N purity is required to obtain the clean molten aluminum obtained by treating with argon gas (5N).

    Holography is an ideal 3D display technique that displays beautiful 3D images. However, it presents some difficulties, one of which is how to capture images under natural light. The holographic stereogram solves this problem, but it requires a large number of pictures that are captured from various directions with narrow durations. Therefore, this paper proposes a new capturing method that uses a small number of multi-view images and a method that creates holograms from the images. The methods are based on estimating the three-dimensional shape of the target objects and generating intermediate images. The effectiveness of the proposed methods is confirmed by computer simulations and optical experiments, which show that the reconstructed images are the same quality as holographic stereograms.

    The purpose of this paper is to show that the officials of the dohana were not specialized financial bureaucrats but grand officials who controlled the general administration of the Norman Kingdom of Sicily. Historians hitherto regarded the officials of the dohana as highly specialized financial bureaucrats who were the most advanced in Europe at that time. In this paper I will examine their evidence, prove it invalid, and, in place of the accepted structure, propose the following structure of administration. During the reign of William II there was a royal council, which consisted of several persons called familiares, at the top of the administration of the kingdom. Before 1169, new members replaced old members of this council one after another and their number fluctuated between three and ten. From 1170 to 1184, however, their number was restricted to only three. The administrative organizations carrying out the affairs proposed by this council and other various tasks, were the three dohanas : the ad-diwan al-ma'mur (curia regis), the dohana de secretis and the dohana baronum. There were three royal palace chamberlains (camerarius regii palatii) at the top of the ad-diwan al-md'mur, several magistri in the dohana de secrdis and three magistri in the dohana baronum. These magistri carried out their administrative duties in the dohana they belonged to. Until the middle of the 1170s one of the three royal palace chamberlains directed the dohana de secretis, and another directed the dohana baronum. In other words, the whole administration of the kingdom was unified in the hands of three royal palace chamberlains. Most of the royal palace chamberlains were Arabs. However, after the middle of the 1170s, an admiral (ammiratus fortunati stolii regii) seems fo have directed the dohana baronum instead of a royal palace chamberlain. This means that the office of dohana baronum was established under the direction of the Arabic bureaucrats in the royal palace first, and that it fell under the control of non-Arabic officials later. It is probable that an admiral, who had far stronger authority than the royal officials and who, in a war, directed counts and barons, was necessary to the dohana baronum, because there were so many fiefs in the areas under the competence of the dohana baronum, and because the vassals and cities had a strong tendency to be independent of the royal authority. These officials of the dohana were grand officials who controlled the general administration of the Norman Kingdom of Sicily.

    Several attempts have been made by scholars to interpret the Bogomils. J.Gouillard(1965)and A.Rigo(1989)have regarded them as members of Byzantine mysticism. H.G.Beck(1993)explained them as ordinary men who led a life with holy modesty and with an attitude of passive resistance against the extravagant Orthodox church. However, many scholars have thought them to be one type of dualist heretic or a revival of the Manichaeans, following St.Runciman(1947), D.Angelov(1947)and D.Obolensky(1948). The author believes that the Bogomils were not only a group of intellectuals, but also an expression of contemporary theological and social problems in 12th century Byzantine History. However, if we presuppose the Bogomils to have been like a school of thought, dualists or mystics or whatever, we cannot understand the real Bogomils on the historical scene. When we examine a social problem regarding"heresy", we have to understand first the reasons why contemporaries treated someone as a heretic. The author, focusing on this way of understanding and treating the Bogomils, surveys them in trials held during the first half of the 1100's in Constantinople. In so doing, this article shows several points that differ from the views of former theses. First, 12^<th> Century contemporaries were unaware of the two precedent sources, the Presbyter Cosmas's Discourse against the Heresy of Bogomil and the Euthymius of Acmonia's Contra Phundagiagites. Secondly, the name"Bogomils"is just one of the criminal labels, which the Orthodox-Byzantines could apply to non-conformers arbitrarily. Thirdly, for the Byzantines, Gnostical cosmology or demonology was not an essential element of the teaching of the Bogomils. There is no identity with thought, theology, moral-code, sectarian movement under the label of Bogomils. On the other hand, in the trials at Constantinople, we find that all of the accused Bogomils equally respected monastic life. The Bogomil-problem first appeared on the official documents after the 10^<th> century. From that time, the power of the monasteries rose, and the number of monks increased. From antiquity, Monks had been very popular in the Byzantine Empire. There were some deviational monks prior to this period, but the subsequent increase in"bonafide"monks also brought its faire share of deviants. This caused growing concern for the Orthodox Church, and in particular regarding their non-controlled activities. If some of them preached heterodoxical sermons to the people, heresy could be easily spread. The insecurity of the Church can be seen clearly in contemporary sources. In conclusion, Byzantines constructed a new type framework for understanding heresy, namely"the Bogomils". They thought deviational monks should be controlled under the heretical label of"Bogomils"as a tool for moral control. In the Constantinople in the 1100's, they were not considered to be dualists. The Bogomils were an indicator of the existence of behavioral problem in those days.
