Title: Supply method for liquid fuel
Inventor: ARAMAKI ISAO
IPC: H01M8/06
Filed: 1982-06-30
Abstract: PURPOSE:To reduce weight and volume and omit the replacement of an inert gas cylinder by adding a device that supplies fuel depending upon the load to the reforming device of a liquid static type liquid fuel battery or a gas fuel battery. CONSTITUTION:The liquid fuel stored in a fuel tank 1 is supplied by a fuel pump 6. Since an electromagnetic opening and closing valve 3 is closed when the fuel in a laminate battery 4 is full, the liquid fuel passes through a bypass and returns to the entrance side of the fuel pump 6 through a pressure regulating valve 7. In this case, the liquid fuel at the exit side of the fuel pump 6 is pressurized to the pressure preset by the pressure regulating valve 7. When current is applied to a load 8, the signal of a current detector 9 enters a control circuit 10 that is driven by the power of the laminated battery 4. The output represented by the function of current is supplied to the fuel pump 6 and the electromagnetic opening and closing valve 3 and the liquid fuel is supplied to the laminated battery 4. As a result, since the pressurized gas for fuel supply is not required, any high pressure cylinder is not required.

Filed: 1994-04-28
Abstract: PURPOSE:To listen to reproducing music without feeling a sense of incongruity at the time of resuming the reproduction after a long period of time since a power source was turned off in the midst of the reproduction by moving an optical head into a starting position of audio data in the forefront. CONSTITUTION:When an Acc switch 11 is turned off, the optical head H is stopped in its position just at this time, while an operation of a servo control part 7 is also stopped to become a standby mode. When the Acc switch 11 is turned on again, and then if it is judged by a main control device 4 that the previous reproducing mode was a normal reproducing mode, the optical head H is brought back into a read-in position by searching for a starting position of the audio data of the leading music, and a reproducing operation is resumed in numerical order of music under the normal reproducing mode. Then, if it is judged that the previous mode was a random reproducing mode, the audio data are selected and reproduced based on data of random sampling numbers, etc., stored in a memory 5. By this method, even after interruption by turning off the power source, you can listen to the audio data without feeling a sense of incongruity.

Title: Alc circuit
Inventor: KAMEYAMA YOSHINORI
IPC: H03G3/20
Filed: 1983-06-24
Abstract: PURPOSE:To obtain proper response characteristics in applying this ALC circuit to a transmission circuit where the transmission state is changed suddenly in a mobile radio or the like by providing an ALC voltage detecting means corresponding to individual causes and providing plural time constant circuits holding individually each ALC voltage. CONSTITUTION:When overdrive is caused in a mobile radio or the like during transmission and the 1st and 2nd ALC voltage are outputted respectively from the 1st and 2nd time constant circuits 7 and 12 because of deterioration in the SWR, a variable gain amplifier 2 is controlled according to them. Since the 2nd ALC voltage is restored in a comparatively shorter time constant than the conventional time constant when the SWR becomes normal, the variable gain amplifier 2 receives the control only at the 1st ALC voltage. When an antenna mismatching detector 10 is actuated with a transmission final stage section 3 at normal state and the 2nd ALC voltage is generated, since the 2nd ALC voltage is kept by the 2nd time constant circuit 12 having a comparatively shorter time constant, when the mismatching is cancelled, the operating characteristics of the variable gain amplifier 2 follow up it and the circuit is restored to the normal state.
