摘要： In a power steering system comprising a power cylinder for assisting a steering power of a steering mechanism, a hydraulic pump for supplying a hydraulic pressure to the power cylinder, a first oil passage and a second oil passage connecting the power cylinder and the hydraulic pump respectively, a motor for driving the hydraulic pump, and power steering control means for calculating a command value to the motor based on the steering torque, a flow rate of the working oil supplied from a high-pressure side oil passage to a low-pressure side oil passage is restrained at the transition from the end of the steering state (lock end) of the steering mechanism to the returning. The flow-rate restraint increasingly corrects a driving current of the motor in the steering direction or limits the flow rate of the working oil.

摘要： A method and apparatus for manufacturing a semiconductor physical quantity sensor according to the present invention achieves the high sensing accuracy and reliability and prevents a sticking phenomenon. Specifically, a semiconductor physical quantity sensor is cleaned by a displacement liquid and is dried while a SOI substrate is revolving. The number of revolutions is determined so that a suction force (FS), which acts on a silicon substrate by a surface tension of the displacement liquid, a sensor spring force FK and a centrifugal force (Fr) generated by the acceleration in the revolution can satisfy the following condition: (FK+Fr)>FS. In order to prevent the sticking phenomenon after the stop of the spray, the semiconductor physical quantity sensor is dried by spraying an inert gas such as nitrogen including minus ions so that the revolving SOI substrate can eliminate static electricity generated by friction of the air flow.

摘要： A rotary damper includes: a pressure generating mechanism portion A for relatively pivoting swingable vanes 4a and 4b with respect to stationary vanes 2a and 2b located on a casing 1 so as to vary reverse proportionally a pressure of a fluid filled within two pressure chambers 5a, 5b, 6a, and 6b; and a damping force generating mechanism portion B which limits a movement of the fluid based on a pressure variation generation at the pressure generating mechanism portion A to generate the damping force. A first transmission mechanism portion C and a second transmission mechanism portion D are interposed between both mechanism portions A and B, each of the first and second transmission mechanism portions C and D being capable of moving the fluid and transmitting the fluid pressure via movable first bellows 12 and second bellows 13. The fluid having a viscosity at least higher than the fluid filled in the flow passage located in the damping force generating mechanism portion B is used as the fluid filled in both of the pressure chambers 5a, 5b, 6a, and 6b in the pressure generating mechanism portion A.
