Title: Vane pump for power steering
Inventor: MOMIYAMA FUJIO
IPC: B62D5/07
Filed: 1979-12-29
Abstract: PURPOSE: To prevent reduction of the steering force beyond the level necessary for the power steering during high speed running of a vehicle such as an automobile and also reduce the engine horsepower consumption.  
     CONSTITUTION: When the pump discharge is increased with increase of the vehicle speed, the pressure in a chamber 40 is reduced with respect to the pressure in a hole 17 by the movement of an orifice 14. When the resultant pressure difference surpasses the force of a spring 20, a flow control valve 16 is moved to the left to eventually close an outlet passage 9 and open a load passage 10 to communicate with a vane pack pressure passage 8. As a result, the negative pressure in the chamber 40 is led into a vane accommodation groove 4 to reduce the urging force exerted to the inner periphery of a cam ring 38 by the top of the vane 5. In consequence, the pump is now operated in a state with a high internal leakage. Thus, the discharge rate and discharge pressure are widely reduced to cause wide reduction of the fluid supplied to a power cylinder (not shown), thus preventing the reduction of the steering force by the power steering.

Title: Duty detecting device
Inventor: NAKAI TOSHIBUMI
IPC: G01R19/255
Filed: 1988-07-11
Abstract: PURPOSE:To enable duty detection by simple circuit constitution without being affected by a frequency by providing a pulse generating means, an up/down counter, 1st and 2nd switching means, and a latch circuit. CONSTITUTION:This duty detecting circuit consists of the pulse generating means 10 which generate two kinds of continuous pulses, the up/down counter 40, the 1st switching means 20 which supplies one of the two kinds of continuous pulses to the counter 40 according to the level of the pulse signal, the 2nd switching means 30 which puts the counter 40 in either of adding operation and subtracting operation, and the latch circuit 50. Then the latch circuit 50 latches the output of the counter 40 when a rising pulse is inputted. The frequency division ratio of the 1st and 2nd continuous pulse is set to 1:2, so when the duty of the pulse signal is 1/3, the counted-up value and counted-down value becomes equal to each other at the time of the transmission of the rising pulse. Therefore, whether the duty of the pulse signal is larger than 1/3 or not is detected from whether the output level of the latch circuit 50 is H or L.

Filed: 1992-06-30
Abstract: PURPOSE:To form a tip position of a blade with extreme high precision by cutting off the tip part abutted on an image carrier after the cleaning member is retained to a retaining member. CONSTITUTION:The position of the tip of the elastic blade 3 is determined by inclination theta of the blade, coordinates Y-Y for the direction of inclination and X-X for the vertical direction. Among these, the precision in the X-X direction can be maintained by the precision of the part because the positioning precision of an attachment surface 6 of the blade holder 4 which is a retaining member consisting of a member which is not elastically deformed when abutted on an image carrier, that is a rigid body. On the other hand, there are more factors for variation due to the method of attachment of the holder 4 and the blade 3 in the Y-Y direction. Therefore, the tip of the blade 3 on the abutted on side to the image carrier is cut off after the holder 4 and the blade 3 are assembled to keep down the variation in size in the Y-Y direction. That is, the elastic blade 3 is cut off in the longitudinal direction after the elastic blade 3 is retained to the retaining member.

Title: Treatment of sewage by activated sludge
Inventor: IWABE HIDEKI
IPC: C02F3/34
Filed: 1991-06-19
Abstract: PURPOSE:To sufficiently exhibit a function even when load fluctuation is made large by regulating the drawing amount of sludge from a reaction tank so that SRT correspondent to the inflow pollutant load is obtained and also regulating the practical ratio of an aerobic treatment time to an anaerobic treatment time in accordance with the inflow pollutant load and controlling ASRT to constant. CONSTITUTION:The drawing amount of sludge due to a pump P1 is regulated so that SRT reversely proportioned to the inflow pollutant load introduced into a reaction tank 1 is obtained in accordance with this inflow pollutant load. In other words, the drawing amount of sludge is increased and decreased in accordance with increase and decrease of the inflow pollutant load. Further the ratio of an aerobic treatment time to an anaerobic treatment time is regulated according to the inflow pollutant load introduced into the reaction tank 1. This is executed by regulating any one or both of an aeration time wherein air is fed into the reaction tank and an aeration stopping time. Thereby since ASRT is controlled to constant, the load of nitrifying bacteria is properly held and activity is not deteriorated and treatment is excellently performed even when load fluctuation is made large.
