Filed: 1985-06-27
Abstract: PURPOSE:To effectively suppress the convention in a melt and improve the quality of a crystal, by connecting a controlling part of a gas pressure of a component having a high dissociation pressure to the melt in a crucible with a narrow route space. CONSTITUTION:A controlling part 20 of a gas pressure, e.g. arsenic, is protruded above inner vessels 18 and 19 closing the atmosphere of a component gas having a high dissociation pressure, e.g. arsenic. A partition wall 21 is provided in a space of an inner vessel from an opening 23 of the controlling part 20 of arsenic pressure and the surface of a melt 24 to prepare a narrow transmission route 26 between an inner wall 25 of the inner vessel and the partition wall 21 to dip the lower end of the partition wall 21 in the melt 24 in a crucible 31. Communicating holes 29 are provided in the contact part of a support 28 supporting the partition wall 21 and the partition wall 21. A narrow space 30 is left between the upper end of the partition wall 21 and the bottom of the inner vessel 18. The temperature of the controlling part 20 of he arsenic pressure is kept at a temperature corresponding to the aimed arsenic pressure to condense the arsenic in the part. A seed crystal is then brought into contact with the surface of the melt 24 to carry out the crystal growth by the pulling up method.

Abstract: PURPOSE:To make spot welding sure without oxidation by juxtaposing a pair of horizontal arm rods to a machine frame, providing a laser light condensing lens and a lower tip to one of these rods and a cylinder device to the other, and pressing an upper tip to objects to be welded. CONSTITUTION:Two sheets of objects 7 to be welded are placed on a lower tip 8, and cooling fluid is transferred to a blast pipe 11; at the same time an inert gas is supplied through a supply port 15 to the cabin on the object side. Thereafter, the inert gas is discharged through a discharge port to prevent the oxidation of weld zones. A cylinder device 17 is driven to move downward an upper tip 18 provided to an output shaft 17a, thereby pressing and fixing the objects 7. Cooling fluid is injected through an inflow port 19 to the inside of the tip 18 to cool the tip 18, and is then discharged through an outflow port. If a laser device 3 is driven here, a laser passes through a condenser lens 6 and forms a focus O at the objects 7, thereby spot welding is performed on the objects.

IPC: H04R17/00
Filed: 1985-06-26
Abstract: PURPOSE:To obtain stable resistance values and reduce number of parts and manhour for assembling etc. by utilizing a thin layer of fluid as acoustic resistance. CONSTITUTION:A thin layer of fluid 33 is formed between the flat part 23b of an insulator 23 and a printed substrate 26 by bringing the printed substrate 26 into contact with a projection 23c and caulking the central part by a rivet 28. In an equivalent circuit, resistance R2 of the thin layer of fluid 33 is resistance for damping resonance. Frequency characteristic of output sound pressure P is flattened by setting the value of the resistance R2. The resistance R2 of the thin layer of fluid 33 is determined by the thickness and length of the thin layer of fluid 33. The thickness of the thin layer of fluid 33 is determined by height (h) of the projection 23c of the insulator 23. The printed board is joined to the insulator with its central part depressed and made to wedge shape. Accordingly, the width of change of thickness of the thin layer of fluid 33 due to dispersion of (h) decreases from outer periphery toward the center, and dispersion of average thickness of the whole is reduced extremely.

Filed: 1987-06-05
Abstract: PURPOSE:To minimize the degree of skewing with a simple structure by forming the shape of either or both of rotary bodies into a curved-face cylindrical body. CONSTITUTION:A sheet of cut paper 7 is housed in a paper guide 6.

Title: Power converter
Inventor: KINOSHITA SHIGENORI
IPC: H02M7/12
Filed: 1978-11-14
Abstract: PURPOSE: To reduce reactive power and harmonic currents by combining a separately exciting converter which is controlled within the delaying power-factor range, a self-exciting converter which is controlled within the gaining power-factor range, and a self-exciting converter whose power factor is 1 or nearly equal to 1.  
     CONSTITUTION: An AC-power-supply system 1 is connected to a power converter comprising a separately exciting converter 31 which is controlled within the delaying power-factor range, a self-exciting converter 32 which is controlled within the gaining power-factor range, and a self-exciting converter 33 which is controlled so that the power factor becomes 1 or nealy equal to 1, and supplies power to loads 41, 42, and 43. Since one self-exciting converter is controlled to yield the gaining reactive power which is used to compensate the delaying reactive power caused by the separately exciting converter, and the other self-exciting conveter is controlled to yield a power factor of 1, the reactive power becomes zero or nearly equal to zero, and the power-supply current is overlapped on the asymmetrical control current with the power factor being 1, thereby the harmonic current can be greatly reduced.

Filed: 1978-11-14
Abstract: PURPOSE: To reduce the change being different from a operation set value and the loaded flowing quantity of a centrifugal separating machine and control the product concentration by cutting and operating a cascade supply quantity and its stage.  
     CONSTITUTION: When a product concentration N p  of cascade is altered, a cascade supply quantity and a supply step are cut and operated together without either cutting and operating a cascade supply quantity or a supply step. Thereby, the changing amount being different from the set value becomes small and the loaded flowing quantity of each centrifugal separating machine can be reduced and, also, the lowering of cascade efficiency can be suppressed. After all, because two operating means is used, two control amounts of a product concentration and a product gas flowing quantity can be controlled and two operations of a product concentration and a waste product concentration can be carried out.
