Title: Dc-dc converter
Inventor: ANDO HARUYUKI
IPC: H02M3/00
Filed: 1990-05-10
Abstract: PURPOSE:To make the title device free from release of emission noise, small in size, light in weight and inexpensive by providing a light-emitting element converting an input voltage into a light and a solar cell receiving the light emitted from the light-emitting element. CONSTITUTION:DC input voltages impressed on input terminals 4a and 4b are impressed on a plurality of light-emitting elements 2 connected in parallel with each other and are converted into lights respectively. The lights emitted from these light-emitting elements 2 are sensed by light-sensing surfaces of solar cells 3 provided corresponding to the elements 2 respectively and are converted into voltages. These solar cells 3 are connected in series and therefore the voltages obtained by conversion are added up and obtained at output terminals 5a and 5b. In this constitution, a circuit construction is very simple and no switching part is provided. Therefore an adverse effect on another circuits, such as emission noise, is eliminated.

Title: Juncture of different optical lines
Inventor: KOKAYU MIKIO
IPC: G02F1/35
Filed: 1988-05-18
Abstract: PURPOSE:To enhance mutual optical coupling efficiency by connecting optical lines which are different in kind from each other via a semiconductor laser amplifier element to each other. CONSTITUTION:The optical lines 11, 12 and the semiconductor laser amplifier element 13 are optical connected to each other via lenses 14, 15. The semiconductor laser amplifier element 13 is maintained in the state just before oscillation by injecting the DC current slightly smaller than the threshold current to the element 13. The semiconductor laser amplifier element in the state just before oscillation is put into the oscillation state by the energy possessed by a light signal when the light signal is made incident from the optical line on a transmission side to the semiconductor laser amplifier element in light transmission. The light signal transmitted in the semiconductor laser amplifier element is then amplified and the amplified signal is made incident to the optical line on a light receiving side from the semiconductor laser amplifier element. The coupling efficiency between the different optical lines is thereby enhanced.

Title: Magnetic recording medium
Inventor: HIKOSAKA KAZUYUKI
IPC: G11B5/738
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium which has high coercive force and sufficient thermal fluctuation resistance and has high recording resolution by forming the medium having a seed layer contg. one of titanium carbide and titanium nitride as an essential component and a magnetic layer contg. a cobalt alloy as an essential component. SOLUTION: The seed layer consists essentially of TiC or TiN and the magnetic layer contains the cobalt alloy as the essential component. The TiC or TiN formed as the seed layer of the magnetic recording medium having such constitution anisotropically grows a ground surface layer to be formed thereon in such a manner that the (100) face of the ground surface layer parallels with the substrate. As a result, the magnetic anisotropy of the magnetic layer formed on the ground surface layer is effectively subjected to intra-surface orientation. Particularly when the TiC or TiN film is used as the seed layer, good crystallinity is obtd. even if the ground surface layer is in a thin state. The crystal grain size of the ground surface layer is thus made fine and the grain size thereof is made uniform.

Title: Module manifold means for distribution of gas stream in reactor
Inventor: HENRITSUKU OTSUTOO SHIYUTAARU
IPC: B01J8/02
Filed: 1988-05-20
Abstract: PURPOSE: To uniformize a flow of a gas passing through a granular material by disposing respective manifold modules of a specific structure consisting of slender tubular objects at specified intervals on the wall surfaces in a reactor. CONSTITUTION: A module manifold means 5 and another part in the reactor are mounted at a tank 1 through a manhole 2. When the reactor is operated after the manhole 2 is closed, the gas flows through an inlet 3 and a passage 4 into the space on a catalyst bed 6, from which the gas flows downward through a manifold means 5. The pressure of the flow of the gas is dropped by sheet-like objects or planar objects 11 having nozzles on the inner side of gratings 9 and, therefore, a uniform flow distribution is achieved between all the modules arranged annularly along the walls of the tank 1. Consequently, the uniform radial flow toward the gratings 7 is generated through the grains of the catalyst bed 6 and the gas flows continuously toward an outlet 8 and emerges from the reactor.
