Patent JP-S62184259-A (JP)
Title: Balancer device in engine-transmission system
Inventor: TERAMOTO TAKAFUMI
IPC: F16F15/26
Filed: 1986-02-10
Abstract: PURPOSE:To reduce torsional vibrations sharply, by generating vibromotive force with balancers in the opposite direction of the torsion of a torsional vibration mode, and setting the vibromotive force to work on a position where the amplitude of the torsional vibration mode becomes wide. CONSTITUTION:A timing belt 15 is wound between a toothed pulley 12 which is provided for the front end portion of the output shaft 5 of an engine 1 and right and left paired pulleys 13, 14 which are retained rotatably on the engine. Generally semicircular balancers 11a, 11b are fixed to the pulleys 13, 14, and they are made to rotate twice as fast as the output shaft 5 and in the same direction. Centroids of both balancers 11a, 11b are dislocated with a phase of 180 deg.. Centrifugal forces T1, T2 are generated by the rotations of the balancers, and torsional vibrations are reduced by their resultant force. As a matter of course, the phase relation between the output shaft of the engine and both balancers is set up in such a manner that moment becomes zero in a crank dead center position. Thus, the torsional vibrations can be reduced, and the mass of the balancers can be made smaller.

Title: Moving coil type cartridge
Inventor: SUYAMA HIDEO
IPC: H04R9/12
Filed: 1981-02-24
Abstract: PURPOSE:To increase an output voltage through longer coil length while keeping the mass and area of board less, by providing a coil on both surfaces of the board. CONSTITUTION:Coils 12, 14 and 13, 15 are formed on front and back of coil supporting plates 6a and 6b. Terminals 13a and 14a are respectively formed at a position corresponding to the front and back of the supporting plates 6a and 6b, and both the terminals 13a and 14a are electrically connected via a through- hole 13b provided at the location of the terminals 13a and 14a at the coil supporting plate 6a (similarly at the coil supporting plate 6b). Thus, electric generation by the coil 13 which was conventionally given, plus that by the coil 14 at the back side can also effectively be used, allowing to increase the output voltage. Since the mass and area of the supporting plates 6a and 6b can not be increased, no deterioration in the sound quality and characteristics can be caused. Thus, the output voltage can be increased while keeping the mass and area of the board less.

IPC: G03B27/50
Filed: 1981-02-24
Abstract: PURPOSE:To ensure a smooth reciprocal motion for an object to be driven, by winding a going wire for the object to be driven to a half side of a common winding pulley drum and a return wire to the other half side respectively with the winding directions reverse to each other and with the winding lead angles equal to each other. CONSTITUTION:A screw lever 93 has a lead angle alpha equal to the wire winding lead angle alpha, and a pulley rotary center shaft 9 is supported by fitting a pulley 25 to the screw lever shaft 93.

Title: Resin cutting device
Inventor: FUJIWARA TATSUO
IPC: B26D1/28
Filed: 1979-03-08
Abstract: PURPOSE: To enable an exact cutting by means of a flat extrusion port block and a cutting edge of a cutter, by a method wherein a rotation is transmitted from a rotary shaft to a cutting tool through a drive pin which is mounted at the rotary shaft and protrudes for wardfor hooking in the cutting tool.  
     CONSTITUTION: A drive pin 40 is fitted in a pin-attaching hole 42 positioned around a hole 32 made in the end of a rotary shaft 14, the end of the drive pin 40 being inserted into a pin-receiving hole 44 made in a cutting tool 18. An inner diameter of the pin-receiving hole 44 is somewhat larger than an outer diameter of the drive pin 40. Existence of said play permits the inclination of the cutting tool 18 in an optional direction within a given range. Thus, if a surface 8a of an extrusion port block and a cutting edge of a cutter 46 are sufficiently flat, the cutting edge of the cutter 46 is brought into good enough contact with the surface 8a of the extrusion port block 2, and thereby the resins extruded to the surface 8a of the extrusion port block 2 from an opening extrusion port 10 is cut as desired.

IPC: G01N21/67
Filed: 1981-02-25
Abstract: PURPOSE:To analyze quickly and accurately, by carrying out the integration of a spectral line after a point of time of eliminating an unstable condition of intensity of the spectral line in an early stage of electric discharge and stabilizing the condition at the time of analizing C or S in an iron material by an LVS (low voltage spark) method. CONSTITUTION:At the time of analizing C and S in an iron material, especially in pig iron by an LVS exciting method, the intensity of a spectral line is unstable in an early stage of electric discharge by deposited graphite or normetallic impurities, but is not affected by the deposited graphite etc. after about  30sec to stabilize it. For this reason, integration of the spectral line is carried  out after an intensity ration of Fe acting as a standard to C and S is kept constant. Hereby, necessary time of the analysis is about 45sec even when a prelimiary discharge time (about 30sec) until the intensity of the spectral line becomes constant, is added and contents of C and S are analyzed in about 1/4  times as compared with an HVS exciting method.

Filed: 1990-02-05
Abstract: PURPOSE:To realize stable adhesion intensity without electrical leakage or short-circuiting even in the case of a photo semiconductor device having unevenness on a surface by having a metal layer whose melting point exceeds a packaging temperature interposed between two layers of indium. CONSTITUTION:In a joint material for packaging a semiconductor element for directly jointing a semiconductor device 5 to a heat sink 1, a metal layer 3 whose melting point exceeds a packaging temperature is interposed between two layers of indium 2, 4. Therefore most unevenness on a surface of a photo semiconductor device 5 is absorbed by deformation of the lower indium 2, and the intermediate metal layer 3 does not melt to have the upper and lower layers of indium separated from each other so that the thickness of the upper layer of indium 4 may not change, thereby permitting the whole semiconductor device 5 to be tightly adhered. Thus even the semiconductor device 5 with an uneven surface can realize stable adhesion intensity without electrical leakage or short- circuiting.
