Title: Noise suppression circuit
Inventor: SATOU TAKESHI
IPC: G11B20/02
Filed: 1979-06-18
Abstract: PURPOSE: To suppress the signal level of the working noise of a tape recorder, by lowering specially the recording level using the attenuator circuit or the like when the sound pressure level applied to the incorporated mike is low.  
     CONSTITUTION: Record detection signal I x  is drawn out from the joint of resistances R 18  and R 20 . Now if the base-emitter threshold voltage VBE of transistor 36 in the circuit is set to 0.6V and also pinch-off voltage -VP of FET32 is large enough with signal (e 3 ) of zero, the source voltage V g  is several volts. In such case, the joint voltage of R 18  and R 20 , i.e. detection signal voltage VX can be set to 0.6V or higher by setting both resistances to the proper levels. In that case, transistor 36 is turned on, and resistance R 12  and R 14  plus filter circuit 38 are formed into the T-type attenuator circuit. Thus the level of record output signal (e 3 ) is attenuated. Accordingly, the signal level for the working noise of a tape recorder can be suppressed.

Filed: 1983-04-30
Abstract: PURPOSE:To lessen speed-changing shocks by supplying the pressure oil of a pilot oil-pressure circuit concurrently to 1-2 shift valve and cutback valve during the 1-2 shift solenoid operation. CONSTITUTION:The first pilot line L1 connected to the port (a) of a manual valve 103 is branched before a 1-2 shift valve 110, and branched first pilot line L1b is connected to the pilot chamber of a cutback valve 115 to work a pressure governing valve 102 toward the decompression diretion during the operation period. The 1-2 shift valve 110 and the cutback valve 115 can thus be operated synchronously during the 1-2 shift-up period. Thus, the pressure of pressure oil to be supplied to the fluid type actuator can be reduced synchronously with the operation of the fluid type actuator and speed-changing shocks can be lessened.

Title: Lens-consolidated projector tube and projection type image receiving machine incorporating the same
Inventor: YANAGI HARUYUKI
IPC: H01J29/89
Filed: 1990-03-28
Abstract: PURPOSE:To make the internal pressure of an optical coupling part equal to the atmospheric pressure and facilitate manufacture of the optical coupling part by providing an air chamber having an opening covered with a continuously porous material in such an arrangement as in communication with the optical coupling part. CONSTITUTION:When the surface of a cooling liquid 2 rises, the air in an air chamber 7 flows out through continuous holes in a continuously porous member 8 covering an opening 9, so that the volume change of the cooling liquid 2 is absorbed in this air chamber 7, and the internal pressure of an optical coupling part is kept constant. Then, if power to a projector tube 1 is shut off, the temp. of the cooling liquid 2 sinks with temp. sink of the projector tube 1. When the temp. of the liquid 2 has returned e.g. to 20 deg.C, the volume of the liquid 2 decreases contrary to the case with temp. rise, so that the liquid surface sinks. With this sink of liquid 2 surface, the external air intrudes into the air chamber 7 via the continuous holes in the porous member 8, so that the internal pressure of the optical coupling part is kept constant.

Title: System and device for high accuracy shearing type load cell
Inventor: KAWABATA MIKIYUKI
IPC: G01L1/22
Filed: 1978-06-26
Abstract: PURPOSE: To achieve higher accuracy by making cavities rectangular to axis on the adjoining boundaries on both sides in the beam axis direction of the bonding faces of shearing-detecting strain gauges.  
     CONSTITUTION: Cavities 28', 28" of flat-bottomed semicircular or other shapes are provided, so as to obviate transmission of axial force to a strain sensing part 18, on the planes along the perpendicular faces 26', 26" on both sides of the strain gauges 20', 22', 20", 22" which are so bonded as to cross at the center of both end faces 16', 16" of the imaginary circular cylinder of the strain sensing part 18. As a result, the strain sensing part 18 assumes the shape wherein both lateral sides of the outside surface of the imaginary circular cylinder are cut off at the perpendicular faces, thus at the time when force is applied at a right angle to the beam axis and the force is to be measured as shearing force, the force in the beam axis direction is insulated by the cavities 28', 28" and is transmitted directly to both upper and lower sides of the gauge bonding faces, and only the shearing force at a right angle to the beam axis passes in the shearing stress concentrating part where the strain gauges 20', 22', 20", 22" have been bonded, whereby the force in the axial direction is cut to zero and errors are thereby prevented.

Title: Tandem impeller
Inventor: SAKAMOTO MASAYOSHI
IPC: F04D29/24
Filed: 1978-06-28
Abstract: PURPOSE: To adjust a tandem impeller to tridimensional flow and prevent the separation of a boundary layer, by curving each vane of the impeller with a roll inclined as to the rotation axis of the impeller and providing a gap between the outlet port of an inlet vane plate and the inlet port of an outlet vane plate.  
     CONSTITUTION: When the vane is curved by rolling, the axis 6 of the roll is tilted as to the rotation axis B-B of the impeller so that the vane fitting angle β on a prescribed radius varies in the direction of the width of the vane. The vane is thus tridimensionally curved. The fitting angle of central plate 2 of the vane differs from that of peripheral plate 3 of the vane on its inlet side as well as on its outlet side. The vane of the tandem impeller consists of the two divided plates. The gap is formed between the outlet port of the inlet plate 1a and the inlet port of the outlet plate 1b. Bypassed flow is conducted from the positive pressure side of the inlet vane plate 1a to the negative pressure side of the outlet vane plate 1b. As a result, the impeller is adjusted to the tridimensional flow and the separation of the boundary layer is prevented.

Title: Optical type karman vortex flowmeter
Inventor: KOSEKI TAKESHI
IPC: G01F1/32
Filed: 1979-06-21
Abstract: PURPOSE: To make it possible to measure a flow rate with high precision while meeting the demand of essential safe explosion-proofing, by introducing an optical measuring method in a Karman vortex flowmeter.  
     CONSTITUTION: Fibers 4 and 5 forming two branches of an optical fiber interforemeter are buried in columnar body 10 generating Karman voltexes. Then, body 10 is placed at right angles to a flow to generate Karman vortex streets, differing from each other, in uniform flow U, and consequently body 10 is affected by strain alternately. This strain varies the optical length of two branches and an optical fiber interference output generates, as shown in the figure c, a wave flux every time a Karman vortex is generated. While the number of semisine waves contained in the waveflux depends upon the magnitude of the strain that the Karman vortex generates, the repetitive frequency of the wave flux agrees with the generation period of the Karman vortex proportional to the flow speed. Therefore, the flow speed and the flow rate of constant sectional area can be measured by measuring the generation period of the wave velocity by measuring circuit part 9.
