Patent JP-H0526198-A (JP)
Title: Diffuser with guide vane
Inventor: NISHIDA HIDEO
IPC: F04D29/44
Filed: 1991-07-24
Abstract: PURPOSE:To reduce noise and improve the performance of a compressor by changing the front edge radius of the guide vane of a diffuser with the guide vane in the vane height direction, and setting the vane angle of the guide vane more on the inner diameter side than the maximum front edge radius to be approximately constant. CONSTITUTION:The radius of the front edge 6a of the guide vane 6 of a diffuser 5 with the guide vane is made small on the side plate 4 side and large on the center plate 3 side. The vane angle of the guide vane 6 at a part smaller in radius than the front edge on the center plate 3 side is constant, and the vane angle of the guide vane at a part larger in radius than the front edge on the center plate 3 side is made larger as the radius becomes larger. Accordingly, discharge flow is approximately uniform in the vane height direction from the outlet of an impeller 1 but fluctuated periodically in the circumferential direction. Since the radius of the vane front edge 6a differs in the vane height direction, the time for the flow from the impeller 1 to reach the vane front edge 6a differs in the vane height direction. In the part smaller in radius than the front edge on the center plate 3 side, the vane angle is made equal to an average flow angle, and on the downstream side from the front edge radius on the center plate 3 side, the flow is led by the vane and decelerated to recover pressure.

Title: Semiconductor laser
Inventor: ISHIGURO NAGATAKA
IPC: H01S5/12
Filed: 1988-07-22
Abstract: PURPOSE:To achieve stable emission in the single axis mode even in high speed modulation by periodically changing the width of an active layer in the direction of beam propagation and making the period several times or less the wavelength of a beam emitted. CONSTITUTION:The basic structure of the embodiment of a 1.3mum band semiconductor laser having an active layer of InGaAsP is buried crescent structure. The width of the active layer is changed by periodically changing the width of a wedge-shaped groove. In this semiconductor laser, the effective refractive index in the active layer changes according to the periodical changes of the width of the active layer 5 to form an internal reflector of high wavelength selectivity. Therefore, a beam can be stably emitted in the single axis mode even in high speed modulation by properly selecting the period of the changes of the width of the active layer. A beam guide layer adjacent to the active layer is not required to enable widening the active layer up to about 2mum for eliminating difficulty in manufacturing.

Title: Controlling method of disc cache memory
Inventor: TANJI MASAYUKI
IPC: G06F12/08
Filed: 1983-10-05
Abstract: PURPOSE:To attain loading/unloading of a memory board in holding the function by constituting a memory interface of a disc cache device like a structure enabled to load/unload an active line and informing the memory board to be loaded/unloaded to a control device. CONSTITUTION:In normal operating status, cache memories 500-800 are filled with data. When a maintenance command is executed from a console 400 to unload a memory board, a microprocessor in a control device 300 sets up flags for access inhibition and data invalidation to two corresponding directories. Conseqently, the block is made unrelated to caching operation and the memory board including the block can be unloaded. If a memory board is to be loaded, the access inhibition flag is reset by the similar procedure. Although the data in the loaded memory board are invalid immediately after the loading, the written data are made valid and then the status before the loading/unloading is gradually restored.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To improve a display characteristic synchronizing a sampling clock signal with a reference synchronizing signal regardless of a change of a master clock signal by generating the sampling clock signal synchronized with the reference synchronizing signal at every prescribed time. SOLUTION: A sampling clock signal generation part 300 is initialized by a synchronization compensated signal SCS generated in a synchronization compensation part 200, and the sampling clock signals CPH1-CPH3 synchronized with a reference synchronizing signal Csync are generated. Then, even when e.g. a first sampling clock signal is generated after a delay of a prescribed time synchronized with the reference synchronizing signal, the sampling clock signal generation part 300 is initialized instantly at the leading edge of the reference synchronizing signal Csync by the synchronization compensated signal SCS generated in the synchronization compensation part 200. Thus, the sampling clock signal CPH1 synchronization compensated by the reference synchronizing signal is outputted.

Title: Liquid fuel burner
Inventor: SHIGEOKA TAKEHIKO
IPC: F23D3/40
Filed: 1983-10-03
Abstract: PURPOSE:To make a variable range of combustion large by maintaining predetermined excess air ratio to a quantity of combustion and to lengthen life of a nozzle, by sucking gasified fuel through an ejector action to be generated by eruption of combustion air. CONSTITUTION:Fuel is sucked by an evaporating element 5, evaporated by heat of a heater 6 and filled within an evaporating chamber 3. Gasified fuel in the evaporating chamber 3 along with air flowing in through an air intake 4 are sucked by ejector effect to be generated when air from a burner fan 9 is erupted through an air nozzle 8 and erupted from a burner part 7a of the tip of a gas nozzle 7. The gasified fuel, therefore, is varied according to an air flow and an excess air ratio can be kept fixed always. Then a quantity of combustion can be made variable stably in a wide range easily by controlling only a qnantity of air to be supplied from a burner fan 9. As for the diameter of an erupting port of the tip of the gas nozzle 7, as the size to such an extent sucking the gas through the ejector effect is good, it is unnecessary to make the title burner so small and it becomes hardly influential even if tar is sticked.

Title: Field-effect transistor
Inventor: FUKUI TAKASHI
IPC: H01L29/778
Filed: 1981-11-20
Abstract: PURPOSE:To obtain a field-effect transistor usable for preparation of an ultraspeed transistor and an ultraspeed integrated circuit by a method wherein a layer of InAsSbP which accords in lattice constant with InAs is inserted between an InAs layer and a gate metal in an InAs field-effect transistor. CONSTITUTION:A field-effect transistor consists of a p or semi-insulated InAs substrate 1, an InAs active layer 2, an n-InAs1-x-ySbxPy layer 3 (y=2.3x), a source 4, a gate 5 and a drain 6. On the other hand, an n<+> region 9 is formed by diffusion or ion implantation. When a forward bias is ''ON'', electrons are induced on the InAs active layer 2 side of a heterojunction interface and a current flows between the source 4 and the drain 6. In the case of a reverse bias, the state of ''OFF'' appears between the source 4 and the drain 6, since the heterojunction interface is depleted. An InAs layer has originally high mobility, and the heterojunction eliminates the scattering due to defects of the interface almost at all. Thus, a transistor of high mobility can be realized.
