    摘要: A first table is provided on a fixed base so that the first table can be moved in one of two directions which cross each other at right angles. A second table is provided on the first table so that the second table can be moved in the other direction. Linear motors for applying the driving force to the first and second tables to directly drive these tables are provided between the fixed base and first table and between the first and second tables.

    摘要: When oil is discharged from an actuator 11i for lowering a vehicle height, an actuator pressure Pa is higher than a pump pressure Pp so that a differential pressure valve 41 slides its valving element 42 to the left by a pressure difference. A valving element seal portion 42b, abutted against a seat face 43a closing an opening of a lower return conduit 40b, moves from seat face 43a and open to lower return conduit 40b. As a result, the closure of the connected portion in the lower return conduit 40b is opened. Thus, the passage of a return conduit 40 is opened. Then, the oil from the actuator 11i is discharged via the return conduit 40 to the reserve tank 16 while receiving less flow resistance by avoiding a passage through any solenoid valve.

    摘要: A differential pressure transmitter has a pressure receiving portion and a sensor portion which are constituted from separate parts separably jointed with each other. The sensor portion includes a semiconductor sensor having one side formed with a resistance pattern and the other side which has a thick-walled peripheral portion and a thick-walled central portion. The semiconductor sensor is incorporated in the sensor portion as being supported at the thick-walled peripheral portion thereof. The pressure receiving portion includes seal diaphragms disposed on both sides of the pressure receiving portion and a central diaphragm disposed therein. The semiconductor sensor is arranged such that the side thereof carrying the resistance pattern faces the pressure receiving portion.
