Title: Three phase ac power feeding method
Inventor: OOHASHI TAKUJI
IPC: B60M3/00
Filed: 1981-06-03
Abstract: PURPOSE:To surely detect a ground fault, in a new urban transit system, by preventing a recirculating flow of zero phase current, induced in a current unbalance line different from the power feeding line to a vehicle, to up and down feeder clables. CONSTITUTION:Another transformer 3C, having capacity half the total capacity of a substation, is prepared, and a selector switch 24 is provided. In this way, even for a fault of either transformer 3A or 3B, electric power can be fed to both feeder buses 60A, 60B, further the buses 60A, 60B are separated from each other by a three phase transformer, and a zero phase current, caused by external induction, can be prevented from recirculation. In this case, though an equipment of the conventional method is utilized as left in that state, in case of setting a new substation, 1.5 times the total transformer capacity is only required by three sets of transformers 3C, 3D, 3E and the total capacity of the transformer can be reduced.

Title: Drying apparatus
Inventor: TOMIZAWA TAKESHI
IPC: F26B9/06
Filed: 1993-04-12
Abstract: PURPOSE:To prevent odor from being produced upon raw garbage and food being dried by performing drying operation with an evaporation portion and a condensation portion being substantially closed excepting their pumping ports, and varying at least one of the evaporation speed or condensation speed of an article to be dried upon the drying operation. CONSTITUTION:As heating of an article 2 to be dried is more quickly promoted, internal pressures in an evaporation portion 1 and a condensation portion 4 are raised owing to evaporation, and inner gas is exhausted from a pumping port 22 in a catalysis portion 19. Odor of the gas is oxidized with a catalyst 20. As the heating is then stopped, vapor resident in the condensation portion 4 is continuously condensed and ther internal pressures in the condensation portion 4 and the evaporation portion 1 are reduced. As a result, a flow of the vapor in the catalysis portion 19 is reversed so that fresh air is forced to flow from the pumping port 22 to the condensation portion 4. With such a Stirling like cycle repeated, a downstream region in the condensation portion 4 is replenished with atmospheric oxygen. Hereby, the catalysis 20 is always supplied with oxygen required for an oxydization reaction. Further, the fresh air goes back and forth through the catalyst 20 whereby drying of the catalyst is promoted.

Title: Component feeding method for mounter
Inventor: SAI IKOKU
IPC: H05K13/02
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To mount a large number of parts efficiently in a short time by enhancing the tact for mounting a component from a feeder. SOLUTION: Parts being fed sequentially by a feeder are sucked simultaneously by a plurality of sucking nozzles and mounted at predetermined positions on a substrate. The parts to be mounted are grouped depending on the type and the dimensions (S1), the grouped parts are sorted in the order of the number of parts to be mounted (S6) and then they are paired according to the number of nozzles (S8). When the number of paired parts differs by one half of the mean value or more (S9), the parts of higher number are divided and fed from a plurality of feeders before being sucked simultaneously (S10). More specifically, when the number of parts to be mounted mismatches between paired parts, the parts of higher number are not fed from one feeder but fed from a plurality of feeders while being divided and sucked simultaneously thus enhancing the mounting efficiency.

Abstract: PURPOSE:To increase a negative resistance by employing a varactor element at least for one of feedback capacitors in a Colpitz type voltage controlled oscillator circuit and controlling a voltage applied to the varactor element. CONSTITUTION:A feedback capacitor C1 connects between a base B and an emitter E of an oscillation transistor(TR), a varactor diode Cv is connected between the emitter E and ground and a surface acoustic wave resonator X is connected between the base B and ground.

Thus, the increase in the equivalent series resistor of the surface acoustic wave element X is compensated and there is no contrary conditions in the frequency variable width and the increase in the negative resistance and the design is facilitated.
