Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a heat radiator which is equipped with no rotating part and comparatively small in mounting space by a method wherein electrodes are provided on a bar-like piezoelectric elements, AC voltages of different phases are applied to the adjacent electrodes to make the piezoelectric element function as a vibrating plate, and the vibrating plate is arranged adjacent to a body to cool. SOLUTION: Electrodes 2 to 9 are provided on a piezoelectric element 1, and an AC voltage is successively applied to these electrodes 2 to 9. Distortion is induced in the piezoelectric element 1 due to a piezoelectric phenomenon to generate mechanical vibrations in the element 1, so that a flow of air can be produced without using a rotating body. Therefore, a semipermanent heat radiator having a simple structure can be realized.

IPC: F27B3/28
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To detect a leakage and operating temperatures with a simple constitution by a method wherein operating temperatures are measured by the electromotive force of a thermocouple and a leakage of metal is detected by a short- circuit between one of strands of the thermocouple and a protection cap and/or a protection pipe when the protection cap melts. SOLUTION: A metal melting apparatus 11 includes an outer vessel 14 and a crucible 13 that contains molten metal 12 and is placed inside the outer vessel 14 with a gap 15 left between them, and the operating temperature in the gap 15 is kept higher than the melting point of the metal 12. A sensor 16 installed in the gap 15 is a sheathed thermocouple 19 with thermocouple strands 18a and 18b inserted through an electrically-conductive protection pipe 17 via an insulating device, and has a metallic protection cap 20 that contains a temperature contact 18d protruding from the lower end of the protection pie 17 with non-contact state kept.  When the molten metal 12 in the crucible 13 leaks and flows into the gap 15, the protection cap 20 melts and conducts to the temperature contact 18d to short-circuit between lead wires 31b and 31c, that causes a leakage detector 33 to detect a fact that a leakage accident happens.

Title: Camera
Inventor: MITSU SHIGERU
IPC: G03B7/16
Filed: 1990-07-11
Abstract: PURPOSE:To obtain a camera which attains an optimum auxiliary light effect in all the photographing states by changing the ratio of the emitted light quantity of a stroboscope to external light by every frame. CONSTITUTION:The voltage of a main capacitor 3 is divided by resistances R1 and R2 and outputted to an A/D.C(voltage measuring means) 7 and the positive input terminal of a comparator(voltage comparing means) 21 as 1st voltage VA. Then, 2nd voltage VD from a D/A.C(calculated value proportional voltage output means) 20 is inputted in the negative input terminal of the comparator 21. The voltage VD is set to be the same as the voltage VA at the time of finishing light emission. When an Xe tube(light emitting tube) 4 starts to emit light, the voltage of the capacitor 3 rapidly drops and the voltage VA also drops. When the voltage VA becomes lower than the voltage VD, the light emission of the Xe tube 4 is stopped. For the photographing of a 2nd frame, the light quantity smaller than the emitted light quantity for a 1st frame is calculated by an auxiliary light quantity arithmetic means 18, and the light emission is performed based on the voltage VD' obtained from a voltage arithmetic means 19 and the D/A.C 20.

Filed: 1980-12-22
Abstract: PURPOSE:To improve the yeidls of rolled materials, by controlling the crown and partial shapes of rolling materials by changing the variable crowns of the work roll, the stay roll, or the intermediate roll. CONSTITUTION:When, for example, rolling is performed after the internal pressure in hollow chambers 6 at both ends of a lower stay roll 5 is adjusted to P1 by enclosing a pressure liquid, the press-contacting surfaces of the hollow chambers 6 are depressed by rolling force received from a work roll 3, and the free surface is swollen.

Filed: 1986-08-01
Abstract: PURPOSE:To easily detect a troubled circuit by holding a bus driver control signal group during a system clock, checking the logical value, counting signal lines outputted to a bus and permitting an FF to hold reports. CONSTITUTION:When bus driver control signals 21-23 are '1', bus drivers 1-3 output bus input signals 24-26 to a bus line 20. When the signals 21-23 stand at zero, the bus drivers come to a high impedance. A clock signal 30 resets bus driver control signal holding circuits 7-9 to attain zero. If the signals 21-23 stand at zero before a next clock comes, said circuits 7-9 keep zero. If the signals 21-23 come to '1', the circuits 7-9 attain '1'. With the output signals 27-29 of the circuit 9 as inputs, a logical value count circuit 10 counts signal lines outputted to the bus, and inputs the output to an FF 11. In a normal state only one of the circuits 7-9 comes to '1', and the output of the circuit 10 attains zero. In case of fault, two or more among the circuits 7-9 come to '1', and the output of the circuit 10 and the FF 11 also attain '1'.

Title: Parallel resonance circuit converter
Inventor: HANSU GEORUGU MATOHESU
IPC: H02M5/45
Filed: 1984-09-03
Abstract: The invention relates to a parallel resonant-circuit converter having at least one intermediate-circuit inductance. In order to guarantee that the inverter will start even with different loads, the voltage produced when discharging a separately charged capacitor across the load is monitored. At some time after the maximum voltage across the load is reached, another separately charged capacitor is discharged via a thyristor of the inverter located in the biasing circuit of the intermediate-circuit inductance. Because of the blocked thyristor and of the capacitor charged to the voltage maximum, the biasing current is forced to flow via diagonal branches and including the load. In this manner, reliable starting of the inverter is possible even with loads having a different natural frequency.
