Title: Method of cleaning electrode for measuring apparatus for component contained in liquid and device thereof
Inventor: DOI SEIJI
IPC: G01N27/07
Filed: 1979-12-27
Abstract: PURPOSE: To make the circumference of said electrode always clean and operate the measuring apparatus for components contained in liquid always accurately, by applying the voltage pulse of the polarity opposite from the voltage polarity at the measurement at every predetermined time.  
     CONSTITUTION: A voltage is applied from a measurement circuit M to an electrode S in order to examine the conductivity of liquid. A timer T produces outputs at the time intervals determined by setting, for example, 2W12hr, and these outputs are applied to a pulse generator PG. Every time when the pulse generator PG receives the output from the timer T, it applies a one-shot pulse to a polarity change-over device PC. The polarity change-over device PC is inserted in the route of applying a voltage from the measurement circuit M to the electrode S, and inverts the polarity of said route. Thereby, the + pole and - pole of the electrode S are connected to the polarities opposite from the polarities up to then once every 2W12hr.

Title: Suction mechanism of sawsh plate type compressor
Inventor: OTA MASAKI
IPC: F04B27/08
Filed: 1993-07-14
Abstract: PURPOSE:To enhance the efficiency by furnishing a communication path between a crank chamber and a suction chamber, and thereby sucking the gas from the crank chamber sufficiently to the compression chamber when a piston is passing around the lower dead point. CONSTITUTION:A communication path 21 is formed as continuing to a valve plate 4 and inside the side walls of a cylinder block 1 and a front housing 2, and one end of this path 21 opens to a crank chamber 2a while the other end opens to a suction chamber 3a. In case the refrigerant gas leaking from the cylinder 1a at the compression stroke is lsee, the refrigerant gas pressure in the crank chamber 2a is sunk below that in the suction chamber 3a by the suction to the compression chamber 20 from the suction passage 19, and the refrigerant gas in the suction chamber 3a moves toward the crank chamber 2a via the communication path 21. Because the gas in the suction chamber 3a is supplied to the crank chamber 2a via this communication path 21, the suction from the crank chamber 2a to the compression chamber 20 is made sufficiently. This enhances the efficiency to lead to enhancement of the performance of the compressor.

Title: Electric power steering device
Inventor: HASHIMOTO AKIO
IPC: B62D5/04
Filed: 1982-10-05
Abstract: PURPOSE:To make the change of a steering feel due to the car speed change smaller by a method wherein a torque is generated at a motor in proportion to a steering torque and yet the energizing of the motor is prohibited when the car speed exceeds a set value. CONSTITUTION:When the car speed detected by a car speed sensor SS is lower than a set car speed Vm set by the variable resistor in a comparator B15, a low level L is applied to the input terminal F of a logic control circuit B16. When steering is performed with a torque larger than the predetermined steering torque, the level of the input terminal A of B16 is set by torque sensors 8 and a pulse is applied to the input terminal B of B16 from a pulse-width modulation circuit B6. B16 controls switching transistors Q1-Q4 in response to the pulses in order to drive a servo-motor DM with a current in proportion to the steering torque. When the car speed reaches the set car speed Vm, a high level H is applied to the input terminal F of B16. Consequently, B16 prohibits the energizing of the motor DM, resulting in increasing the steering torque by the amount developed by the motor DM.
