Title: Rotary vane pump
Inventor: TAKAGI AKIRA
IPC: F04C2/344
Filed: 1992-02-07
Abstract: PURPOSE:To set precompressing pressure to the average value of working pressure without causing any problems of separation phenomenon of vanes. CONSTITUTION:A cylinder 29 is provided with a path 50 for introducing pressure reaching precompressing process alpha in a pump chamber 46 into back pressure chambers 43a in respective vanes 44 constituting the pump chamber 46. Thus, the pressure getting higher than discharge pressure (back pressure) in the pump chamber 46 during the precompression process alpha when used under the condition of low working pressure is introduced through the path 50 into the back-pressure chambers 43a of the vanes 44 constituting the pump chamber 46 in the precompression process alpha to maintain always the pressure balance relation to the pump chamber 46 so that even if the pressure in the pump chamber 46 is increases the tip of the vane 44 is not separated from the inner peripheral surface of the cylinder 29.

Title: Squelch circuit
Inventor: TSUKUNI MITSUTAKA
IPC: H04B1/10
Filed: 1979-02-27
Abstract: PURPOSE:To make equal the detection voltage of the detection circuit in the  squelch and normal states, by the equal impedance for the squelch circuit in the both states. CONSTITUTION:In the normal state when the equelch switch 21 is ON, the transistor Tr14 is in operating state and a given negative voltage is produced to the emitter. Thus, a given back bias is fed to the varactor diode 38, the capacitance of the  diode 38 is low and high impedance is caused. In the squelch state when the squelch switch 21 is OFF, no collector current of Tr14 flows and the emitter voltage is the same level as the negative power supply voltage. But since the cathode side of the diode 38 is open in DC, no back bias voltage is applied and the diode 38 is at high capacitance. The load impedance viewed from the capacitor 13 is determined with the impedance of Tr14 in normal state and determined with the impedance of the diode 38 in squelch state. The constant is selected to obtain equal impedance for the both states.

Title: Engine with reserve chamber
Inventor: ODA HIROYUKI
IPC: F02D13/02
Filed: 1982-02-15
Abstract: PURPOSE:To improve burning performance, fuel consumption and emission and  operation performance, by a method wherein valve colsing timing of an auxiliary valve which opens and closes a reserve chamber is made variable, and the valve closing timing at the time of a light load is set so that it is delayed until after the valve closing timing at the time of a heavy load. CONSTITUTION:A reserve chamber 11 is formed on a cylinder head 3, which reserves a part of suction air in a combustion chamber 5. An auxiliary valve 12 is provided on an opening part 11a of combustion chamber of the reserve chamber 11. Dynamic valve mechanism 14 detects an engine load, adjusts a timing cam 17 of the auxiliary valve 12 and sets valve closing timing of the auxiliary valve 12 so that it is delayed at the time of a light load and quickened at the time of a heavy load. Thus, although reserve pressure is increased at the time of the light load, it is decreased at the time of the heavy load and unification of a jet speed can be contrived. A swirl at the time of the light load can be enlarged and burning performance can be improved in this manner.

Title: Voltage detecting circuit
Inventor: NAKAMORI TSUTOMU
IPC: G06F1/24
Filed: 1982-02-16
Abstract: PURPOSE:To secure the output of a power-up detecting circuit by inserting a threshold element into the 1st inverter stage load of said detecting circuit and thus causing an abrupt drop of the output of the trailing inverter from a desired relatively high level to the ground level. CONSTITUTION:A P channel transistor (TR) 6 as the threshold element is connected in series between the P channel TR2 of the inverter stage 2 and a terminal for a power voltage VCC. In response to a rise this VCC, the potential at a point A rises. As a result of the interposition of the TR6, the voltage across the TR2 and a TR3 is (VCC-Vth), where Vth is the threshold voltage of the TR6 and about 1V. Therefore, the threshold value of the CMOS inverter consisting of the TRs 2 and 3 is (VCC-Vth)/2. The potentials at points A and B are fixed to the clamped value by a TR1, so the TR3 turns on before they cross (VCC-Vth)/ 2 and a C-point output is at the ground potential; when (VCC-Vth) rises above  the potential at a point B, the TR2 turns on. The conduction of the TR2 causes  a D-point output to drops from about 3V to the ground potential.
