Title: Screw vacuum pump
Inventor: UCHIDA RIICHI
IPC: F04C25/02
Filed: 1984-07-25
Abstract: PURPOSE:To assure vacuum stably by operating with low speed at start while fully closing the intake valve arranged at the intake side to reduce the torque and controlling the rotary speed such that the intake pressure will be substantially constant under normal operation. CONSTITUTION:Under stoppage of vacuum pump 51, the intake valve 54 is fully closed T0. Upon throw-in of power source under this condition, an inverter 57 will produce the frequency proportional with the voltage to start the high frequency motor 53 with low frequency thus to rotate the vacuum pump 51 with low speed. Consequently, the torque is reduced. Upon reaching of the pressure between the intake valve 54 and the vacuum pump 51 to the upper limit, (T1), the signal from pressure sensor 55 is converted by converter 56 into an opening control signal for intake valve 54 interlocked with the intake pressure thus to open said valve 54. Upon reaching to the lower limit (T2), signal is fed from the converter 56 to an inverter 57 to produce such frequency as the rotary speed of vacuum pump 51 will cause said pressure thus to maintain the intake pressure constant.

Abstract: PURPOSE: To measure the horizontal degree simply and remotely by embeding plural pairs of transmitting and receiving ultrasonic transducers in the side wall in the lengthwise direction of the cylindrical container of the bubble system level so that the transmitting and receiving units are placed opposite to each other.  
     CONSTITUTION: The cylindrical container 1 of the bubble system level is placed on a proper bed the bottom face of which is a plane, the fitting of the container and bed is adjusted so that the bubble 3 is located at the center when the bed is horizontally placed. Ultrasonic wave is oscillated from plural transmitting ultrasonic transducers 4 embeded in the side wall in the lengthwise direction of the container to the receiving ultrasonic transducer 5.

Abstract: PURPOSE:To shorten the investigation time of the cause of abnormality, by connecting a short-circuiting bar at a specific position of the interface of each microcomputer when detecting the abnormality of data transfer between microcomputers. CONSTITUTION:A microcomputer A when transferring data on a copy command sends a request signal REQ.O to a microcomputer B. The microcomputer B receives the signal REQ.O and informs the microcomputer A of a data transfer ready state after data transfer is held in readiness. Once receiving the REQ enable signal (REQ.E), the microcomputer A starts the data transfer. An internal interruption takes place in the microcomputer A and B right after the transfer is completed, then data is judged. When abnormality is found in the data and a fault position is switched off, the short-circuit bar 6 is connected. Consequently, the REQ.O of the microcomputer A is connected to the REQ.E of the microcomputer A directly and then a data diagnosis is started.
