IPC: B66B1/00
Filed: 1988-10-31
Granted: 1994-01-26
Abstract: The start-lock detecting circuit of an elevator in an elevator starting circuit for controlling an up/down operation command relay sequence includes a control circuit having a main CPU for the elevator operation control, an elevator operation command motor controlling CPU, and a register and decoders forming data transmission circuits for supplying data to the main CPU and motor controlling CPU for receiving the data information value to set the main CPU via an AND gate, and a motor control relay sequence circuit for detecting contact point state of a relay from the motor controlling CPU to a drive circuit and a hybrid circuit of the control circuit. Thus, if an abnormal lock-detection relay is not magnetized at the elevator starting lock, this state is checked in the CPU for reinitializing and a door is open for the safety of passengers in a cage while the up/down operation command information value is supplied again by searching out a call signal unless the safety system of the elevator's path is broken, thereby improving efficiency of service.

Abstract: 디지털 통신장치에서 송신부 구성시 π/4-DQPSK방식으로 송신신호를 변조하여 출력한다. 이를 위하여 변환기는 코딩된 데이터 스트림을 수신하여 홀수 데이터 X K 와 짝수 데이터 Y K 로 분리한다. 그러면 신호 맵핑부는 X K 신호 및 Y K 신호를 수신하여 두신호의 논리상태를 분석한후 두신호를 논리상태에 따라 맵핑하여 인페이즈 I K 신호 및 쿼드러츄어페이즈Q K 신호를 생성하고 디지털 여파기는 I K 신호 및 Q K 신호를 수신하여 I K 신호 및 Q K 신호를 필터계수와 콘벌루션하여 심볼간의 간섭을 제거한다. 이후 D/A변환기는 디지털 여파 하는 디지털 I K 및 Q K 신호를 아날로그 I K 신호 및 Q K 신호롤 변환하며, 스무심 필터는 상기 아날로그 신호를 완만하게 여파한다. 
     이후 송신단에서는 아날로그 I K 신호 및 Q K 신호를 캐리어 신호와 승산하고, 승산한 두신호를 가산하여 π/4-DQPSK 변조신호로 출력한다.

Abstract: The device for controlling a screened waste residue collector, quickly or correctly controls a hydranlic pump for driving the waste residue collector, a motor for moving the main body horizontally, and a motor for driving a waste discharging conveyor. The waste residue collector has a hydraulic pump (HP) for tilting and driving an ellvator, a reversible motor (TM) for moving the main body horizontally, a belt conveyor motor (BCM) for transferring the waste. The hydraulic pump (HP) for controlling a piston with solenoids (SV1, SV2) for tilting and driving the elevator back and forth and solenoids (SV3, SV4) for lifting the elevator. The hydraulic pump, the belt conveyor motor and the reversible motor are selectively driven by magnets (MS1), (MS3), (MS2F, MS2R) of a selection switch.
