Title: Method of controlling number of revolution of input shaft of hydro-mechanical transmission in power recovering operation of vehicle
Inventor: KINOUE KENJI
IPC: F16H47/04
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of excessive rotation and stop of an engine while controlling the number of revolution of an input shaft at the time of power recovering operation of a vehicle by controlling a pump swash plate angle of a hydraulic pump and a motor swash plate angle of a hydraulic motor so that the predetermined torque is applied to the input shaft. SOLUTION: A hydrostatic transmission 200 is formed by connecting a hydraulic pump 2 and a hydraulic motor 3 through a closed circuit 4. A swash plate type piston pump is used for the hydraulic pump 2 and the hydraulic motor 3, and angle of each swash plate 2a, 3a is controlled in the predetermined range. The closed circuit 4 is connected to an accumulator 5 through a first - a third supply and discharge lines 73, 75, 76. In the case of power recovering operation of a vehicle (at the time of deceleration), a controller 10 sets the swash plate 3a of the hydraulic motor 3 at an angle capable of being operator for power recovery, and controls the angle of the swash plate 2a of the hydraulic pump 2 on the basis of the predetermined computing expression.  With this operation, the predetermined braking torque is applied to the input shaft, and the number of revolution of the input shaft is controlled so as to be held at the predetermined value.

Title: Safety cut-off actuator
Inventor: KOJIMA TADASHI
IPC: F16K31/12
Filed: 1980-11-21
Abstract: PURPOSE: To enable a load to return back surely to the original position by releasing the pressure generated through a forcibly-flowing apparatus in a chamber by means of a valve device opened in response to the cut-off signal applied from outside.  
     CONSTITUTION: If an earthquake sensor 28 senses an earthquake or a gas sensor 29 senses gas leak when fluid is flowed forcibly toward a second chamber 8 by means of a plunger 4 and an output is supplied from the sensor to a control circuit 23 through an OR circuit 30, the control circuit 23 immediately cuts off the control signal being supplied to a coil 24. Accordingly a valve member 27 is moved to its open position and the fluid within the second chamber 8 goes back to the first chamber 7 through a connection route 10, resulting in rapid down of the pressure in the second chamber 8. Thus the load can be reduced again surely to the original position.

Title: Agc system for optical communication
Inventor: FUJIOKA FUMIO
IPC: H04B10/00
Filed: 1982-09-24
Abstract: PURPOSE:To reduce the error of an AGC operation and to improve the quality of a received picture, by superposing a pilot signal only to a synchronizing signal having a fixed level on DC. CONSTITUTION:When an output (a) is obtained from a TV camera 1, a synchronizing signal extracting part 2 extracts a synchronizing signal out of the output (a). A switching part 4 outputs a pilot signal (c) to a superposing part 5 on the basis of the detection signal (b) and the superposing part 5 superposes the output (c) to the output (a) and applies the superposed signal to an optical transmitter 6. The transmitter 6 feeds the received signal as an optical signal. A photodetector 8 receives the optical signal transmitted through an optical fiber 7, converts the received signal into an electric signal again, then outputs the electric signal to an AGC amplifier 11. The amplified signal is inputted to a pilot signal extracting part 9. The extracting part 9 extracts only the pilot signal component out of the transmission signal and applies the extracted signal to an AGC input generating part 10. The generating part 10 generates an AGC input and applies the input to the amplifier 11. On the basis of the control input, the amplifier 11 executes the gain control of a video signal, and supplies the controlled signal to a monitor device 12.

Title: Switching power supply parallel operation control device
Inventor: MATSUDA HIDESHI
IPC: H02J1/12
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent a load current from being concentrated on one power supply by detecting the unbalance of output, based on the temperature of each switching circuit in each switching circuit, and by outputting a correction signal for correcting the output voltage to a control circuit, so that a load rate to be applied to each becomes uniform. SOLUTION: A switching power supply parallel operation control device is composed of power supply circuits 51 and 61 which are connected to a load 70 in parallel, resistors 52, 53, 62, and 63, and operational amplifiers 54 and 64. In the power supply circuit 51 with a high output voltage, since the temperature coefficient of a resistor 52 is set large than that of the resistor 52, the change in the resistance value for the temperature increase of the resistor 52 becomes larger as compared with that of a resistor 53, thus reducing a divided voltage by the resistors 52 and 53, and converting the increase in heat generation operation due to the unbalance of a current to a voltage change, which can be set to a control element. In this case, a correction signal for correcting output is sent to a control circuit 55.

Title: Image pickup device
Inventor: DATE NOBUAKI
IPC: H04N5/335
Filed: 1984-08-07
Abstract: PURPOSE:To obtain an image pickup device in which S/N will not deteriorate when an exposure time is short by setting an exposure control period so that it may be just before periodical reading. CONSTITUTION:When a high level signal is outputted from an output terminal of an AND gate 17 in time t2, time measurement of a timer circuit 19 is executed by T2 only. Here, (T2-T1) is equivalent to exposure time and the (T2-T1) is automatically set by a manual, luminance of an object, etc. In the time t7 when from time t2 to time T2 pass, a pulse output is outputted from the timer circuit 19, the pulse is converted to a pulse with a prescribed level and a prescribed width by a one-shot circuit 21 and supplied to a shutter driving circuit 202. Since time measurement time T1 and T2 of a timer are set so that an exposure completion timing may be just before a read timing, a dark current can be almost neglected after exposure, and the dark current until exposure is started is removed by a clear action. Therefore, a picture signal with good S/N can be obtained.

Filed: 1993-07-05
Abstract: PURPOSE:To provide a deceleration sensor for detecting the deceleration based on the movement of a mover sliding in a housing in which bouncing of the mover at the stroke can be prevented through a simple structure upon application of a high deceleration. CONSTITUTION:A mover 4 is housed slidingly in the housings 2, 3. A stopper 5 regulates the displacement stroke of the mover 4. Springs 9, 10 are arranged on the opposite sides of the mover 4 in order to urge the mover 4 toward the stopper 5 with a predetermined combined force. A fluid channel 11 becoming shallower toward the left side is made in the inner wall of the housing 2 while conducting the spaces on the opposite sides of the mover 4. When the mover 4 moves close to the left stroke end, the fluid resistance of the channel 11 increases to lower the displacement speed of the mover 4 and thereby the conductive plate 8 does not bounce on the electrodes 6, 7.
