Title: Reference voltage generating circuit
Inventor: KOBAYASHI YOICHI
IPC: H01L21/822
Filed: 1990-03-06
Abstract: PURPOSE:To form the reference voltage generating circuit whose temperature characteristic is satisfactory without necessiting the trimming by varying an applied voltage applied to a resistance value adjusting circuit from the outside and varying resistance values of plural bias resistances. CONSTITUTION:The circuit is provided with resistance value adjusting circuits Q3, Q4, Q11 - Q13, and Q21 - Q23 for short-circuiting the resistance concerned in plural bias resistances R1, R2, r1, and r2 connected in series to an emitter of a second driving transistor in accordance with a level of an applied voltage applied from the outside. Accordingly, by applying a suitable voltage to an external terminal 3, the MOS transistors Q3, Q4 are turned on or off, and a value of a temperature characteristic correction resistance can be varied. In such a way, it is also unnecessary to redesign the temperature characteristic correction resistance and it can be set to an optimal value, and the reference voltage generating circuit whose temperature fluctuation is very small is obtained.

Title: Steering power control device for power steering device
Inventor: NAKAMURA KYOICHI
IPC: B62D5/083
Filed: 1986-03-17
Abstract: PURPOSE:To prevent noise made by a fixed throttle, by connecting a flow control valve with the fixed throttle serving as a bypass to a communication passage for communicating a passage on the side of a servo valve with a passage on the side of a reaction mechanism through the fixed throttle and discharging a rate of flow in front of the fixed throttle to a low pressure side. CONSTITUTION:A feed passage 45 is communicated with a relief passage 47 by a communication passage 90 through a fixed throttle 91 and the communication passage 90 is connected to a flow control valve 92 with the fixed throttle 91 serving as a bypass. The flow control valve 92 is actuated by a differential pressure b, c across the fixed throttle 91. When the differential pressure is greater than a pressure PG produced by a gear when a vehicle travels at a high speed, an excessive rate of flow is fed to a low pressure side. With this arrangement, a rate of flow q1 in back of the fixed throttle 91 can be controlled to constant when the pressure PG produced by the gear exceeds a prescribed value. Therefore, noise made by the fixed throttle 91 in the communication passage 90 in steering at a low speed can be prevented.
