Title: Hybrid vehicle
Inventor: YAMAGUCHI KOZO
IPC: B60L50/16
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To generate power corresponding to necessary demand load for driving a vehicle when a generator is connected with an engine, a part of engine output is transmitted to the generator, and the residual portion is directly transmitted to an output shaft. SOLUTION: An accelerator opening α is used as a necessary demand load. When the accelerator opening α is lower than or equal to a specified value, the number of revolution of a generator is fixed by engaging a brake B. The higher the necessary demand load is (the accel opening α is large), the larger the consumption power of a motor 4 becomes. When the accelerator opening αis larger than or equal to a specified value, the brake B is opened, and the number of revolution of a generator 3 is increased in proportion to the accel opening α, thereby increasing the amount of power generated. Motor torque is so controlled that torque changes due to generator driving is absorbed by the motor.

IPC: G01F1/84
Filed: 1990-06-20
Abstract: PURPOSE:To make it possible to detect also abnormality due to a change with time by a method wherein a sensor tube is once vibrated in a state of no fluid being made to flow therethrough and then stopped, a state of attenuation of vibration after stoppage is compared with a reference state of attenuation and thereby the abnormality of the sensor tube is judged. CONSTITUTION:A power source is made, a sensor tube (tube) is vibrated by vibrators 13 and 14, and an operating switch 19 is turned ON in a state of a fluid stop signal being inputted to an excitation control means 18. Then the means 18 supplies a control signal to the vibrators 13 and 14 through a drive circuit 20a so that the tube be stopped. Therefore the vibration of the tube is attenuated gradually and stopped. A detecting means 20b detects the attenuation of vibration of the tube from output signals of pickups 9 and 10 and supplies a detection signal to a judging means 21. Using a clock from a timer 22, the means 21 compares a vibration level (amplitude) after passage of a prescribed time after stoppage of the vibration with a reference level and judges the tube to be normal when the vibration level is within an error of the reference level, while judging it to be abnormal when the vibration level exceeds the error. Receiving an abnormality signal from the means 21, an alarm means 23 issues an alarm.

Filed: 1983-09-02
Abstract: PURPOSE:To attain the record and reproduction with the same hardware even in case the media different in level of recording density are used, by compressing a bit and therefore having a margin of processing time. CONSTITUTION:An input signal is converted into the binary data after A/D conversion and supplied to an arithmetic logical circuit 7. In the 1st clock mode, the binary data is stored to a register 8 by inhibiting an operation of the circuit 7 via a logic control circuit 10, an order control circuit 11 and a control memory circuit 12. In the next clock mode, the compressed comparison data is read out of a coefficient memory circuit 6 in case the decision output obtained by a switch 9 is positive. Then the bit obtained in response to the comparison arithmetic result of the circuit 7 is set by the circuits 7 and 10, the memory 12 and the circuit 11 to obtain the compression data. No compression is carried out when the decision output of the switch 9 is negative. The result of the compression data is added with an error correction code or interleaved by a data memory 13 to be modulated and recorded.

Abstract: PURPOSE:To offer the zoom lens barrel which is made shorter in overall length, simple in structure, and advantageous in cost by structuring a cam ring in two separated bodies, rotating and moving them forward and backward at the time of zooming, and moving one body straight at the time of focusing. CONSTITUTION:The zoom ring 4 is provided rotatably to a fixed frame 1 and rotated at the time of zooming and the zoom ring 5 can freely be rotated and moved forward and backward inside or outside the zoom ring 4. The zoom rings 4 and 5 are coupled by a coupling member 4f and cam grooves 4a and 4b and cam grooves 5c and 5d are provided. Then the zoom rings 4 and 5 are rotated on the optical axis to move all lens groups forward and backward in the direction of the optical axis and thus vary the focal length, and the zoom ring 5 is moved forward and backward to move only a focusing lens group forward and backward and thus perform focusing operation. Therefore, the zoom rings 4 and 5 are arranged one over the other, so the overall length of the lens barrel can be made shorter and the zoom lens barrel which has short overall length can be realized.

Title: Snubber circuit, switching power source using the snubber circuit, and surge voltage absorbing method
Inventor: SHIMAMURA TAKASHI
IPC: H02M1/00
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a flyback type switching power source of high efficiency in which surge voltage is not generated. SOLUTION: A circuit, in which a capacitor 7 and an MOSFET element 3 are connected in series, is connected in parallel with a primary winding 31 of a flyback type switching power source 2. The gate terminal of the MOSFET element 3 is connected with one end of an auxiliary winding 4. Magnetic coupling between the auxiliary winding and the primary winding is with a polarity such that the MOSFET element 3 can be electrically continuous, when a semiconductor switching element 9 is a cutoff state. When an element 9 is in a cutoff state, first the MOSFET element 3 operates in the third quadrant and the capacitor 7 is charged with energy stored in a leakage inductance. Next the capacitor 7 is discharged, a current is made to flow in the primary winding 31, and stored energy is transferred to the secondary side. Efficiency is high, and surge voltage is not generated.

Title: Instantaneous gas water heater
Inventor: UNO SHIGEKI
IPC: F23N5/00
Filed: 1986-07-10
Abstract: PURPOSE:To provide a safer and more convenient small-sized instantaneous gas water heater by a method wherein an electromagnetic valve is controlled with an electro-motive force of a main thermocouple within a specified time after an igniting operation is carried out and the electromagnetic valve is controlled with a complex electro-motive force of a reverse thermocouple which is opposite to the main thermocouple after a specified time elapses. CONSTITUTION:An impressive voltage for an electromagnetic valve 15 is changed over to a sole electro-motive force of a main thermocouple 13 and a complex electro-motive force of the main thermocouple 13 and an opposite thermocouple 14. When an igniting operation is carried out, the electromagnetic valve 15 is opened, gas is flowed in a pilot burner 9 and then the gas is ignited with an ignitor device 7. Since a timer switch 16 is kept closed, only the electro-motive force of the main thermo-couple 13 is applied to the electro-magnetic valve 15 during 30secs after ignition, thereafter a timer switch 16 is automatically opened and a complex electro-movitive force which is a difference between an electromotive force of the main thermocouple 13 heated by a pilot burner 9 and an electro-motive force of the opposite thermocouple 14 heated by a main burner 8 is applied. The electro-motive force reaches to a saturated electro-motive force after 30secs of ignition. There is no possibility that the flame is diminished due to a lack of electro-motive force, resulting in that a shutting- off voltage in the electro-magnetic valve 15 can be increased and CO/CO2 is hardly outputted and so a safety in operation can be improved.
