Title: Clamp-type resonant link inverter with noise margin
Inventor: ANDORIYUU PII WAISU
IPC: H02M1/08
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy by sampling each phase current which is fed to an induction motor each time, when the voltage across a bus decreases toward zero immediately before the zero voltage is reached. SOLUTION: When a DC bus reaches a zero voltage, it is detected by a regulator 22 responsive to the voltage on a line 43 and then switches 155-160 are turned on to short-circuit the bus, which is thereby reset to zero always during each resonance cycle. Signals on the lines 27, 32, 33 are used for detecting the moment of time immediately preceding the turn off of a clamp 170 for resetting the bus voltage to zero. Scaling amplifiers 45, 46 reduce the voltage level of lines 32, 33 and apply the reduced voltage to comparator circuits 49, 50 through lines 47, 48. An output is delivered, when the indication of clamp current on the line 27 is lower than that when the clamp transistor 170 is turned off. When outputs are fed from the comparator circuits 49, 50 onto the lines 51, 52, an AND circuit 55 delivers a sampling signal on a line 56 to current sensor gates 19-21.

Title: Overvoltage protecting device for optical ignition thyristor
Inventor: KANEDA HIROTOSHI
IPC: H01L29/74
Filed: 1991-11-07
Abstract: PURPOSE:To reduce an overvoltage while suppressing a decrease in dynamic characteristics and to improve reliability by providing a clamp circuit for suppressing an overvoltage generated at the time of an optical ignition between a gate electrode and a cathode electrode to a predetermined clamp voltage. CONSTITUTION:When a receiver of an optical ignition thyristor 1 is irradiated with a light signal 10 to be optically ignited, an overvoltage VGK is generated between G and K as a voltage VAK between A and K is lowered at a falling rate dV/dt, and applied to a Zener diode 11. The diode 11 becomes conductive during a period in which it exceeds its Zener breakdown voltage VZ to suppress the overvoltage VGK to the voltage VZ. Accordingly, if the voltage VZ is set to a range which does not exceed a gate allowable loss allowed between the G and the K at this time, a PB layer 5C disposed between a gate electrode 7G and an auxiliary gate electrode 8G is protected against a damage due to the overvoltage and a thermal breakdown due to a gate loss. Thus, dynamic characteristics such as optical ignition sensitivity, dV/dt characteristic, etc., can be stabilized.

Title: Heat transfer tube and heat conveying system
Inventor: KISHIMOTO AKIRA
IPC: F28F13/12
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To reduce in size a heat exchanger without lowering heat transfer characteristics even in the case of using an aqueous solution obtained by adding a surfactant as a heat conveying medium by providing an agitating means for agitating by applying a shearing force to a heat conveyor flowing in a heat transfer tube. SOLUTION: A twisted flat plate 13 having a width equal to an inner diameter of the cylindrical heat transfer tube 12 is inserted fixedly into inside of the tube 12. The plate 13 is obtained by twisting a tape-like flat plate and twisting it at a predetermined pitch. A heat conveying medium flowing in the tube 12 is agitated by the plate 13, and a heat transfer performance of the medium is improved. Generally, in the solution, a surfactant having a hydrophobic base part and a hydrophilic base part is self-gathered so that the hydrophilic part of a center is surrounded on its outer periphery with the hydrophobic part to form a bar-like micell. Thus, this is entangled in a high order to exhibit a viscoelasticity. However, a shearing force is applied to the medium by the plate 13 to agitate the medium, the entangled micell is disentangled so that no viscoelasticity is developed.

Title: Seat reclining device
Inventor: YAMADA YUKIFUMI
IPC: B60N2/235
Filed: 1993-11-19
Abstract: PURPOSE:To improve operability of a rotating shaft by receiving the reaction force by a load receiving mechanism so as not to be applied to a rotating shaft when load for rotating an upper arm is input in the state that the rotation of the upper arm to the lower arm is regulated. CONSTITUTION:While the rotation of an upper arm 2 to a lower arm 1 is regulated, when load for rotating the upper arm 2 is applied to the upper arm 2, the load is received by the engagement of a pole 1 with a ratchet 52, and its reaction force is received by press contacting between a recessed part 61 and a projecting part 62, and respectively transmitted to the lower arm 1. Thus, while the rotation of the upper arm 2 to the lower arm 1 is regulated, the load for rotating the upper arm 2 applied to the upper arm 2 is transmitted to the lower arm 1 not through the rotating shaft 3. Accordingly, the rotating operation of the rotary shaft 3 can be always secured in a good condition not to disturb the operability.

Title: Automatic transmission for vehicle
Inventor: KONO KOZO
IPC: F16H61/00
Filed: 1993-10-27
Abstract: PURPOSE:To prevent occurrence of any delayed actuation of an actuator at the time of starting in a cold district or under the cold weather by opening/ closing little by little the solenoid valve of a select actuator, thereby raising the oil temperature. CONSTITUTION:An oil temperature-raise controlling means 12 is prepared, which opens/closes a solenoid valve 8 little by little, so that the working oil passes the solenoid valve 8 of a select actuator 5. With this, the temperature of the working oil is raised by the friction heat caused by flow resistance of the working oil, which is produced when the working oil passes the solenoid valve 8. As a result, the viscosity of the working oil is lowered, so that the speed change control thereafter can be conducted quickly and smoothly. In addition, since the temperature of the oil is raised by the opening/closing control of the solenoid valve 8 for driving the select actuator 5, the gear is maintained in its neutral position even if the select actuator 5 is driven. Therefore, an accident such as unexpected engagement of a gear or unexpected movement of a clutch 2 can be avoided, thereby ensuring safety.

Title: Freezing cycle of refrigerant
Inventor: TOZAKI JUN
IPC: F25D11/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent a compressor from being rendered in the state of liquid compression by using only a partial interval of a refrigerant return pipe as a parallel piping, and operating a two-way valve provided on the one piping by actuating the same such that compressor interruption and full close of the same are brought into synchronism and that timing of full open is delayed with respect to operation starting. SOLUTION: A refrigerant return pipe 5 coupling an evaporation pipe 4 and a compressor 1 is branched at a branch part 5a, on one of which a two-way valve 8 is disposed and on the other of which an auxiliary capillary tube 9 is disposed. They are joinned at a joint part 5b as one piping. A refrigerant that is balanced in its high pressure part and low pressure part upon interruption of the compressor 1, and is directed to flow into the evaporator 4 where it is stored in an air/liquid mixed state flows into the compressor 1 through the refrigerant return pipe 5 simultaneously with the starting of compressor operation. Herein, the two- way valve 8 is kept fully closed for a predetermined time just after the starting of the operation of the compressor 1 whereby the returned refrigerant from the evaporator 4 is returned to the compressor through the auxiliary capillary tube 9.  Thereafter, the two-way valve 8 is fully opened to bring the operation to stationary one. Further, the two-way valve 8 is fully closed upon the operation interruption of the compressor 1, and hence a reverse flow of the liquid refrigerant from a suction side circuit is prevented.

Filed: 1986-12-10
Abstract: PURPOSE:To calculate normal coordinate values of feature points by generating another dimension auxiliary lines parallel with a normal coordinate system at the point where dimension auxiliary lines parallel with the normal coordinate system and oblique dimension auxiliary lines intersect each other on the outside line of a graphic or within the graphic and calculating distances between these dimension auxiliary lines. CONSTITUTION:A dimension auxiliary line angle assigning means 7 assigns dimension auxiliary lines parallel with a normal x-y coordinate system and dimension auxiliary liens parallel with an X-Y coordinate system of local coordinates inclined to said x-y coordinate system. If dimension auxiliary liens parallel with the normal coordinate system and those parallel with the local coordinate system intersect each other on a graphic line F or within the pattern, a dimension auxiliary line generating means 9 generates another dimension auxiliary lines parallel with the (x) axis and the (y) axis of the normal coordinate system at these intersections. A distance data generating means 11 successively calculates and stores distances between dimension auxiliary lines having the same angle with respect to all dimension auxiliary lines on the normal coordinate system and those on the local coordinate system.

Abstract: PURPOSE:To reduce the entire processing time of a synthetic aperture radar signal and also the range migration correction processing by providing an indirect address memory section storing range location information and a counter storing an offset of an memory address. CONSTITUTION:The range at each transmission between the synthetic aperture radar and a location on the earth to be visualized is calculated by a control section 5 and converted into a range location at each transmission and all the locations required in the azimuth direction are stored in the indirect address memory section 2. The memory address to be accessed to a picture memory section 1 is generated continuously at a high speed by adding the range position information of one azimuth line read sequentially from the indirect address memory section 2 and an output of a counter 3 giving the offset of the address of the picture memory section 1 by an adder 4. Thus, a data from the same range location equivalently is read in the azimuth direction from the picture memory section 1 and the range migration correction processing is attained.
