20110094433UNDERWATER POSTURE STABILIZATION SYSTEM AND DIVING APPARATUS EQUIPPED WITH THE SAME - Provided is an underwater posture stabilization system which, by being attached to various underwater equipment such as undersea equipment and underwater vehicles having different shapes and positions of the center of gravity according to their purpose and the like, allows simply and reliably setting their posture in water (basic posture), is excellent in versatility, is not only excellent in posture stability since, when the posture inclines under the effect and the like of tidal currents and pulsating currents, a moment to restore the posture to its original posture naturally acts, but is also capable of easily changing the posture as needed, and also is capable of stably controlling the posture even in the presence of complicated tidal currents and pulsating currents, and is excellent in reliability, stability, and certainty of posture control. The underwater posture stabilization system includes a frame to be attached to an apparatus body of the underwater equipment, a pair of sliding portions arranged so as to be freely movable back and forth on both side portions of the frame, a support member freely movable up and down which is fixed at a lower end thereof to each sliding portion, and arranged upward or obliquely upward, and a floating body arranged at a tip of each support member.04-28-2011

20080206078ELECTRIC PUMP UNIT AND ELECTRIC OIL PUMP APPARATUS - In an electric pump unit, communication between arcuate ports provided in correspondence with a discharge side and a suction side of an internal gear pump is selectively permitted and prohibited in correspondence with movement of a spool of a relief valve. If fluid pressure at the discharge side of the internal gear pump becomes greater than or equal to a predetermined value, the spool moves across an inner arc of one of the arcuate ports corresponding to the suction side of the internal gear pump and from a position at which the spool prohibits the communication between the arcuate ports to a position at which the spool permits the communication. As the spool moves away from the position at which the spool blocks the communication between the arcuate ports, the opening degree of the relief valve changes in accordance with a downward convex curve.08-28-2008
