Title: Thin-film transistor
Inventor: UKAI YASUHIRO
IPC: H01L29/78
Filed: 1987-01-23
Abstract: PURPOSE:To enhance the mobility of a field effect by a method wherein an active layer at a thin-film transistor to be used for an active liquid-display device is constituted by a heterojunction superlattice. CONSTITUTION:As an active layer 21 at a thin-film transistor which is applied to a top-gate type stagger structure, hydrogenated amorphous silicon carbide a-Si1-xCx (where x<0.5) is used for a well layer and another hydrogenated amorphous silicon carbide a-Si1-xCx (where x> 0.5) is used for a barrier layer; a multilayer laminate is constituted by laminating the two alternately. The active layer 21 is formed by a glow discharge method using silane gas SiH4 and acetylene gas C2H2. If amorphous silicon carbide a-Si1-xCx (where x > 0.5) is used for a gate insulating film 22, it is possible to form the gate insulating film 22 in succession after the formation of the active layer 21. If the amount x of carbon for amorphous silicon carbide a-Si1-xCx is more than 0.5, the conductivity in relation to the amount of carbon for amorphous silicon carbide is reduced remarkably. The mobility due to the electrical conduction of false two-dimensional carriers is increased by a quantum effect, and a big current drive force is obtained.

Title: Pressureless bonding method of friction material and adhesive agent used for this
Inventor: KAMIOKA NOBUO
IPC: F16D69/04
Filed: 1979-02-09
Abstract: PURPOSE:To bond friction material simply through primary sintering under no pressure, reduce bonding equipment and considerably lower bonding cost by using copper or copper alloy as an adhesive agent at the time of bonding the friction material to a copper-plated mounting plate. CONSTITUTION:A sintered friction member of Fe base composed of the mixture of non-metals such as corhart and metals such as Fe, Cu, Ni and Sn is bonded to the surface of a mounting plate such as copper-plated iron plate. In this case, the adhesive agent composed of Cu3P or the mixture of Cu3P and Cu is interposed between the mounting plate and friction material and the materials are sintered under no pressure for 1hr at a temperature of 1050 deg.C. Since the sintering temperature is higher than the melting point of the adhesive agent, the greater portion of the adhesive agent assumes liquid phase and reacts with the copper-plated iron plate in a good state. It also permeates into the friction material as well through voids, thereby firmly pressure bonding the friction material and copper-plated iron plate in a metallic bond state. There is no need for any pressing jig, pressing furnace, etc. and considerable reduction is achieved in equipment cost and bonding cost.

Abstract: PROBLEM TO BE SOLVED: To achieve a decrease in load on developer, etc., and a substantial increase in the life of the device by rotating an inner cylindrical member having small holes for developer passage which are made in its periphery, and mixing and stirring incorporated electrified particles and developer released from a developer storage member, thereby electrifying the developer. SOLUTION: An inner cylindrical tube 50 is rotated and driven by a first drive mechanism, and also a development bias is applied by turning on a bias power source. Consequently, toner T is released into an empty space 71 through the mesh 61 of a toner storage tube 60, then mixed and stirred with electrified particles 70 as the inner cylindrical tube 50 is rotated and moved, so that it is electrified to a specific polarity. Then, together with the electrified particles 70, it reaches an area corresponding to the supply opening 42 of an outer cylindrical tube 40. As the result, most of the electrified toner T facing the supply opening 42 is attracted to an electrostatic latent image on a photoreceptor drum 20 by the action of the development bias by the bias power source, therefore the electrostatic latent image is rendered visible.

Abstract: PROBLEM TO BE SOLVED: To quickly output image data just by reading again the image data without setting again an image mode by holding memory of the corresponding image mode stored in an image mode storage means even if the image data being outputted are cancelled by an image cancellation means. SOLUTION: A copying machine can perform a printing operation, a reading operation and an image reading operation independently of each other by its multijob function. If a reader is reading image data when other image data are cancelled, this reading operation is discontinued and the image data are cancelled. When a stop key 304 is pushed, both reading and printing operations are discontinued. Then it is determined whether the image data should be cancelled, i.e., whether a clear key 303 is pushed. If the image data are cancelled, only the image data are cancelled and an image mode is kept as it is.

Title: Method and device for analyzing crystal structure
Inventor: NAKAJIMA KIICHI
IPC: H01L21/66
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To judge the existence of a mosaic structure even for a crystal having no mosaic structure anisotropy by comparing a plurality of standardization diffraction profiles obtained by converting the incident angle of X rays into a standardization incident angle with one another. SOLUTION: The reflection measuring of a crystal surface 3 is performed by inclining a substrate around an X ray incident direction while the X ray incident direction (dotted line A-B) is fixed and causing the crystal surface 3 to be a vertical surface. That is, by changing the reflection surfaces in sequence while fixing the X ray incident direction, a plurality of diffraction profiles are measured. The intensity of such a diffraction profile is divided by a peak intensity to be standardized. Also, each incident angle θ is converted into a standardization incident angle obtained by dividing a difference between a maximum incident angle and each incident angle α by the cosine of an angle made by a reference crystal angle and a crystal surface 3 and thereby a standardization diffraction profile is obtained.  Such standardization diffraction profiles are compared with one another and, based on whether the shapes of the standardization diffraction profiles of all the crystal surfaces coincide with one another or not, the existence of a crystal mosaic structure is judged.
