Abstract: A compact vibrator support structure has a very high “vibration confinement effect”, and includes a vibrator, vibrator support members, and a vibrator base, which supports the vibrator in midair via the vibrator support members and is made of a material having a specific gravity of about 3.0 or above. Since the high vibration confinement effect of the vibrator support structure reduces leakage of vibration from the vibrator base, the stability of the vibration of the vibrator is greatly improved, thereby increasing the detecting accuracy of angular velocity. This eliminates the need to enlarge the vibrator base or to adhere a weight thereto, resulting in a miniaturized vibrating gyroscope.

Abstract: A valve assembly HAS an element movable in a mechanical journal arrangement relative to a valve opening to establish an opening position of a valve, and A control unit for controlling the application of an oscillatory electromagnetic force to the element (8) having an known peak amplitude to cause the element to execute a sympathetic oscillatory motion as a friction reducing maneuver.

A monitor detects changes in the opening position of the valve during each of the measurement periods and provides a measure thereof. A processor is connected to the control unit and to the monitor to determine a working amplitude of the oscillatory electromagnetic force at which the detected changes will be minimized and to supply the determined working amplitude to the control unit.

Abstract: An electromagnetic valve device reduces wear of a moving member and a non-magnetic member sliding against the moving member and prevents contamination from contacting the sliding part. The moving member is directly and movably supported in a reciprocating manner by a non-magnetic cup. The moving member has a hard layer made of nickel containing PTFE (polytetrafluoroethylene) particles at the sliding part located against the cup. The hardness of the hard layer is high and is approximately the hardness of the stainless steel cup. Therefore, the wear of both the moving member and the cup can be reduced. The hard layer contains the PTFE particles, and therefore the sliding part between the moving member and the cup is lubricated by the PTFE, which reduces the sliding resistance at the sliding part and improves the responsiveness of the device.
