摘要:
To minimize the amount of air that may enter the damper chamber in a normally closed solenoid valve to stably maintain the damper capacity, the normally closed solenoid valve has a valve housing and a movable element. A cylinder having an open end is formed in one of the valve housing and the movable element. The cylinder has an inner diameter smaller than the outer diameter of a trunk of the movable element. A piston provided on the other of the valve chamber and the movable element is movable relative to the cylinder as the movable member moves. The piston is inserted into the cylinder through its open end to define a damper chamber between the piston and the cylinder. A restricted passage is formed between the damper chamber and the valve chamber through which hydraulic fluid can be moved between the valve chamber and the damper chamber.

A vibrating gyrosensor includes a support substrate on which a wiring pattern having lands is formed. A vibrating element is mounted on a surface of the support substrate. The vibrating element includes a base part having a mounting surface on which a number of terminals connectable to the lands is formed. A vibrator part integrally projects from a side of the base part and has a substrate-facing surface coplanar with the mounting surface of the base part. The vibrator part has a first electrode layer, a piezoelectric layer, and a second electrode layer which are laminated on the substrate-facing surface. The vibrator part vibrates when an AC signal is applied between the first and second electrode layers. The central electric field strength of the AC signal is set at a position shifting to the positive direction from the center of a hysteresis loop of the piezoelectric layer.

A frame body comprises a first face portion on which a compressive force acts in case a load is applied, a second face portion on which a tensional force acts, and third and fourth face portions which connect the first and second face portions. The third and fourth face portions are respectively equipped with a reinforcing member which comprises a base portion which is away from the frame body and plural base portions which project from the base portion and are joined to the frame body. The convex portions have plural convexities which are arranged so as to extend both in the longitudinal and sectional directions of a frame.
