Title: Slide bearing
Inventor: KAMIYA SHOJI
IPC: F16C33/12
Filed: 1988-08-31
Abstract: PURPOSE:To aim at enhancing the antiseizing ability, a wear resistance and a fatigue resistance with an additional process which is simple and cheap by forming an alumite layer on the outer surface of a lining material, by forming a close contact surface over the outer surface thereof so that the close contact layer follows up a roughened surface thereon, and by forming an overlay layer on the outer surface thereof. CONSTITUTION:A close contact layer 4 is formed by Ni-plating, Cu-plating or the like over the roughened outer surface of an alumite layer 2 which is formed over the outer surface of aluminum group alloy lining material 1, the close contact layer 4 being laid following up the roughened outer surface. The outer surface of an Pb group overlay layer 5 formed on the roughened surface of the close contact layer 4 is smoothened. Accordingly, it is possible to increase the adhesion force between the alumite layer 5 and the close contact layer 4 only with an additional process which is simple and cheap, thereby it is possible to enhance the antiseizing ability, the wear resistance and the fatigue resistance.

Title: Method for constructing atomic power plant
Inventor: YAMANOI KOZO
IPC: G21C13/00
Filed: 1987-09-02
Abstract: PURPOSE:To improve working efficiency and to shorten the construction period of a reactor building by forming the uppermost floor of the building and installing a moving type crane thereon, then progressing the carrying and installing of in-pile equipment to a reactor pressure vessel and building of the upper floors of the buildings in parallel. CONSTITUTION:After a foundation mat 4 of the building 1 is installed, a reactor container 2 is installed and wall bodies 5 and floor surfaces 6 of the building are successively built from below to above. The moving type crane 23 is installed to the uppermost floor 7 and the pressure vessel 3 is installed to the container 2 at the point of the time when the uppermost floor is formed. The in-pile equipment can then be carried and installed into the container 3 by utilizing the crane 23. The building construction work and the carrying and installing of the in-pile equipment are thus executed in parallel without requiring a tower crane to be used for the construction work of roof trusses 9, etc., to be executed simultaneously in parallel therewith. The construction period is extremely shorted by this method.

Title: Production of magnetic recording medium
Inventor: YASUNAGA TADASHI
IPC: G11B5/85
Filed: 1987-09-02
Abstract: PURPOSE:To contrive a film forming speed by heating and melting a magnetic material essentially consisting of iron and directing the vapor flow onto a nonmagnetic substrate, then directing material flow which is mainly the fast neutron particle flow essentially consisting of nitrogen components toward the nonmagnetic substrate, thereby providing the thin magnetic film of an iron nitride system on the substrate. CONSTITUTION:The nonmagnetic substrate 2 is held on a substrate holder 1. Iron 9 heated and melted by an electron beam 8 is evaporated to vapor flow 11 which is directed onto the substrate. Gaseous nitrogen is introduced from a gas introducing port 7 simultaneously therewith and the fast neutron particle flow 12 is generated by operating an ion gun 6 provided with an ion neutralizing means 3 in an ion gun drawing out port. This particle flow is directed toward the nonmagnetic substrate. The ion neutralizing means heats a filament 4 to release thermions and directs the thermions toward a counter electrode 5 so as to cross the beam. The beam is thereby made into the fast neutron particle flow 12. The average energy of the fast neutron flow is determined by the acceleration voltage in the ion gun 6. The film forming speed is thereby increased and the magnetic recording medium is produced.

Title: Manufacture of semiconductor device
Inventor: OOKUMA TOORU
IPC: H01L21/3065
Filed: 1983-11-18
Abstract: PURPOSE:To enhance the reliability by forming an insulating film on the side of an electrode layer, forming the stepwise difference of a smooth film surface, thereby preventing an overhung portion from forming on an interlayer insulating film and preventing the stepwise disconnection of metallic wirings. CONSTITUTION:After an aluminum film 3 is formed as an electrode wiring layer through an insulating film 2 on a semiconductor substrate 1, a silicon dioxide film 5 is formed by a CVD process as the second layer, the film 5 is anisotropically etched, and the film 3 is etched to produce an undercut. A silicon nitride film 6 is formed by a plasma CVD process on a pattern having a T-shaped sectional shape formed in this manner, plasma etched to allow the silicon nitride 6 to remain only on the side wall of the layer 3, thereby flattening the stepwise portion. Thus, the surface of the film 4 to be formed thereafter becomes smooth, a preferable insulating film having no overhang is obtained, and the stepwise disconnection of the aluminum film used for upper electrode wirings can be eliminated.

Title: Vertical transistor
Inventor: SAITOU MINORU
IPC: H01L21/331
Filed: 1982-12-14
Abstract: PURPOSE:To operate the transistor more efficiently, and to flow high currents by forming a reticulate region in high concentration connected to a base terminal to a base layer on the lower side of an emitter region. CONSTITUTION:The N<+> reticulate regions 7 are formed to a P type substrate 1 through selective diffusion and an N type epitaxial layer 2 is grown, and P<+> isolation layers 3, the P<+> emitter region 4 and N<+> base extracting layers 8 are formed from the surface on the anti-substrate side through diffusion. The N<+> reticulate regions 7 extend in the N base layer 2 during these diffusion processes, and fringe sections connect to the N<+> layers 8. Consequently, bias between a base and an emitter functions effectively extending over the whole surface of the emitter region 4. As a result, the transistor operates on the whole surface of the emitter as shown in the arrow 9, and high currents can be flowed. Accordingly, the occupying area of the transistor can be reduced, and an effect of which the hFE of a low-current region is difficult to be lowered is displayed because the region is difficult to be affected by the surface.

Title: Method and reagent for diagnosing urinary cancer
Inventor: INADA MASAMI
IPC: G01N33/493
Filed: 1986-09-19
Abstract: PURPOSE:To discover the urinary cancer in an early period by dividing a soln. in which the radioactive bonded materials formed by adding radioactive cobalamin to urine exist, adjusting the solns. to specific two pH values and measuring the quantities of anions at the respective pH. CONSTITUTION:The radioactive cobalamin is added to the urine to be measured and is bonded to the carcinoprotein and normal protein to form the respective bonded materials. For example, <57>Co-cyanocobalamin is used as the radioactive cobalamin. The soln. in which the radioactive bonded materials obtd. in such as manner exist is divided to two parts which are then adjusted to different 3.5-5.0pH by adding a buffer soln. thereto. The quantities A, B of the anions in the low pH and high pH solns. are measured and the ratio A/B is determined. The ratio A/B becomes higher when the amount of carcinoprotein in large, and lower when the amount is normal. Since the ratio of the quantities of the anions at the respective pH is determined, the urinary cancer is discoverable in an early period by the simple method.
