Patent JP-H023026-A (JP)
Title: Optical switch
Inventor: OTA KOSAKU
IPC: G02F1/313
Filed: 1988-06-20
Abstract: PURPOSE:To realize an optical switch which has no movable part and whose power consumption is small by turning ON and OFF an applied voltage to a multi-layer electrode having conductive layers laminated at the interval of m/2 times of wavelength along the advance direction of a light beam used for a T-shaped optical waveguide. CONSTITUTION:A multi-layer electrode 3 having conductive layers 6 laminated at the interval of m/2 [provided that (m) is a natural number] times of wavelength along the advance direction of a light beam used for a T-shaped optical waveguide 2 is provided so that the surface of its conductive layer 6 makes an angle of 45 deg. against the incident direction of the light beam, and also, makes an angle of 90 deg. against both side faces of a cross contact part. In this state, when an applied voltage is turned ON to the multi-layer electrode 3, a refractive index of the cross contact part of the T-shaped optical waveguide 2 is varied, and accordingly, an incident light is reflected thereby. When the applied voltage to the multi-layer electrode 3 is turned OFF, the refractive index of the cross contact part is not varied, therefore, the incident light travels straight. In such a way, since an optical switch having no movable part can be constituted, the power consumption can be reduced.

Abstract: PURPOSE:To improve the performance of servo control without preventing the mutual effects of servo control systems by selecting the speed servo control system to control requirement, in which speed servo is effective, and selecting the phase servo control system to control requirement, in which the phase servo control system is effective. CONSTITUTION:When a speed servo control system is chosen, both changeover switches SW1, SW2 are connected on the terminal (b) sides. When a servo lock signal is input from the comparator 13 of the speed servo control system and the speed servo control system is servo-locked, a recording mode or a regenerative mode is decided, and recording processing is executed as it is on the recording mode. Both change-over switches SW1, SW2 are connected to the terminal (a) sides in order to transfer to phase servo control on the regenerative mode. When a servo lock signal from the comparator 10 of a phase servo control system is output, regenerative processing is executed.

Title: Surface coated throw-away chip for cutting
Inventor: SUGISAWA TAIJIROU
IPC: C23C30/00
Filed: 1981-09-25
Abstract: PURPOSE:To develop excellent cutting capacity over a long period of time, by forming a softened layer to the scoop-up surface of the base of a surface coated throw-away chip to reduce high temp. plastic deformation as well as to secure toughness. CONSTITUTION:A WC base pressed powder body is sintered to prepare a throw- away chip made of a WC base hard alloy having a softened layer with a thickness of 10-200mum throughout the total surface thereof. The surface part other than the scoop-up surface of this throw-away chip is removed by grinding and honing is applied to the ground part. In the next process, a hard layer comprising TiCN or the like is formed on the surface thereof by a chemical vapor deposition method or a physical vapor deposition method. Because this surface coated throw-away chip has the softening layer formed only to the scoop-up surface thereof, plastic deformation is hardly generated. Therefore, the recession or the initial abrasion of a blade chip are reduced and excellent cutting capacity is developed over a long period of time.

Title: Solid-phase joining method
Inventor: MAKINO MITSUO
IPC: B23K20/00
Filed: 1984-07-23
Abstract: PURPOSE:To minimize deformation of a pair of objects to be joined and to join surely said objects by heating the objects then pressurizing axially the objects and pressurizing the joint part in the direction perpendicular to the axial direction thereby joining the objects. CONSTITUTION:A pair of objects 5, 5 to be joined are grasped respectively by chucks 2, 3 and a joint part 5a is set between an upper jig 10a and a lower jig 10b of a restraining jig 4 for deformation. After the entire part of the device is maintained in a vacuum inert gaseous atmosphere, the jig 4 is heated to heat the objects 5, 5. When the objects 5, 5 attain a specified temp., the objects 5, 5 are axially pressurized by axially pressurizing cylinders 9, 9 and at the same time a pushing means 14 is lifted by the lower cylinder 13 of the jig 4. The joint parts 5, 5 are held for specified time while the joint part 5a is pressurized in the direction perpendicular to the axial direction. The deformation is thus suppressed and the press contact force to the end face of the part 5a is increased. The solid- phase joining with high strength is thus accomplished.

Title: Compressor of air conditioner
Inventor: YANO MIKIO
IPC: F04B39/00
Filed: 1982-09-03
Abstract: PURPOSE:To prevent the occurrence of the liquid back phenomenon by incorporating an inflow restricting valve which is actuated according to the oil pressure from an oil pump part, at the sucking port for refrigerant in order to obstruct the inflow of the refrigerant into a compressor by said inflow restricting valve when the compressor is interrupted. CONSTITUTION:With a compressor interrupted, a compressor shut (not shown) is also interrupted so that the oil pressure stays at a low value of approximately 5-6kg/cm<2>G. At this time, a valve body 22 is urged by the pushing force of a spring 25 of the inflow restricting valve 26 to go into the condition as shown by the figure (a), wherein a sucking port 8 is closed so that the inflow restricting valve 26 completely restricts the inflow of refrigerant. Resulting that liquid back may be prevented will evade the possibility of an accidental damage caused by that the compressor directly compresses non-compressive liquid refrigerant. If the compressor becomes into the overdriven condition, the valve body 22 begins to close the sucking port 8 by the increased oil pressure so that circulation of refrigerant more than required may be inhibited.
