Abstract: An induction motor control apparatus for controlling the power factor at which an induction motor 12 operates includes sensors and circuits CT, 22; 16, 24; 26 for periodically detecting the effective (RMS) values of current and voltage supplied to the motor winding during a fixed number of cycles, e.g. one cycle, and multiplying these to obtain a value of apparent power of the motor, together with circuits CT, 146, 28 for detecting the working power of the motor, with the power factor of the motor being thereby accurately obtained. That detected power factor is compared with an ideal value of power factor, to obtain an error amount that is applied to control the motor voltage. The ideal power factor is obtained by multiplying a designated value of power factor by a compensation amount that is determined in accordance with the motor load, thereby ensuring that stable operation of the motor is achieved even under the no-load condition. <IMAGE>   <IMAGE>

Abstract: detecting if there is an edge of image from output data of a shading correcting circuit(305); emphasizing the edge of the output data of the shading correcting circuit(305) according to an edge detecting signal generated in the detecting step to allow a signal processor(311) to middle-tone-processes it. The method provides high definition picture by emphasizing the edge of the output data without requiring expensive analog filter.

Abstract: [목적] 
     배터리 6을 전원으로 하여 전오기 3을 구동하는 동시에 감속 토크에 의한 회생전력에 의해서 배터리 6을 충전하는 전동기 제어수단 20을 구비한 배터리카의 제어방법에 있어서 회생전력을 효율좋게 회수하여 에너지수지를 향상시킨다. 
     [구성] 
     전동기 제어수단 20의 직류주회로 입력축에 대용량의 콘덴서 21을 병렬접속하고 콘덴서 21의 충전전압의 소정전압보다도 낮을때에 배터리 6축으로부터 콘덴서 21측으로 흐르는 전류를 제한하면서 공급하고, 회생전력에 의해서 콘덴서 21의 충전전압이 소정전압보다 상승하였을때에 콘덴서 21측으로 부터 배터리 6측으로 흐르는 전류를 제한하면서 배터리의 전압이 규정전압에 도달할때까지 충전하고 배터리 6의 전압이 규정전압에 도달한 경우에 콘덴서 21의 충방전 전류로 전동기 3을 구동하는 배터리카의 제어방법.

Abstract: An air cleaner of car having a sensor loading chamber(5) having a temperature sensor(5b), a smoke sensor(5c) and a lighting bulb(5a); a motor(6); plural air vents(4) formed in outer wall and bottom wall; filtering part(20) comprising a filter(21) and an activated carbon filter(22); and a ventilation fan(30) is disclosed. The air cleaned is attached to the roof of the car. Thereby, the car room air is more cleaned and it is possible to utilize room space better than prior art because the air cleaner(1) is attached to the roof(50).
