Title: Control circuit and control process for vacuum cleaner
Inventor: BAEK SUNG-MYON
IPC: A47L9/28
Filed: 1991-07-10
Granted: 1993-08-31
Abstract: The  method  prevents  the  dust  detective  capability  from dropping and acknowledges and displays the fault of the  detection device. Even if the detection device has an accumulation of  dust, the  circuit  keeps  the  dust  detection  voltage  and  the  dust detection range to a constant value. When  it  outputs  the  pulse signal into a current controller (70), if the output voltage level of a voltage checking section (80) keeps a low  voltage  level,  a controller (60) acknowledges  that  the  detection  device  is  in trouble and runs the suction motor and outputs the control  signal to the indication device  (90)  and  displays  that  it  is  in  a trouble.

Abstract: 본 발명은 진동자등과 같은 외부부착부품이 없고, 수작업에 의한 조정이 필요없으면서도 회로규모가 작으며, 경년변화가 작은 IC화에 적합한 스테레오신호의 복조회로를 제공하는 것을 목적으로 하며, 이 복조회로는 제1 발진신호와 이 제1 발진신호에 대하여 90°의 위상차를 갖는 제2 발진신호를 발생하는 전압제어발진회로( VCO )를 가진 PLL 회로를 이용하여 스테레오신호의 복조를 행하며, 상기 VCO 는 입력에 대하여 출력위상이 90°다른 신호를 출력하는 제1앰프 및 제2앰프와, 입력에 대하여 출력이 위상이 180°다른 신호를 출력하는 제3앰프를 접속하고, 이들 회로에 의해 입력신호에 대하여 360°비켜놓은 출력신호를 발생시키고, 이 신호를 입력측에 피드백하여 발진하며, 상기 제1앰프 및 제2앰프의 동작전류가 상기 VCO 의 발진주파수를 제어하기 위해 상기 PLL 회로에 있어서 발생하는 제어전압신호에 따라서 제어되고, 상기 제1앰프 및 상기 제2앰프의 출력중 어느 하나로부터 상기 제1발진신호가 취출되고 상기 제1 앰프 및 제2 앰프의 출력중 어느것으로부터 상기 제2발진신호가 취출된다.

Abstract: The hydraulic circuit controls continuously the pressure of hydraulic actuators so that it may check the vibration generated from the irregular running state and improve drive conformability. It comprises the hydraulic actuator(30); a variable hydraulic pump(38) pumping fluid for the actuator(30); a pilot pressure control valve(36) closing the circuit between the actuator(30) and the pump(30); proportional solenoids(36S,20S); a controller(32) controlling the hydraulic pressure based on the signals from a vehicle posture detector(31) and an abnormal state detector(29).
