IPC: B25B5/06
Filed: 1992-02-25
Abstract: PURPOSE: To provide a device for retrieving a sunken object which does not need to be lowered into water from a point just above the object by an operator. CONSTITUTION: A submersible grappling system 10 is designed for retrieving objects, such as, golf balls from the bottom of a body of water. The grappling system is made up of a tubular housing 12, a bladder 16 at one end of the housing, finger-like retrieval elements 18 at the opposite end of the housing and a gear column 14 which serves to interconnect the bladder and retrieval elements. When the gear column is driven in one direction, it will cause the bladder to be compressed within one end of the housing while forcing the retrieval elements downwardly and outwardly into surrounding relation to an object to be retrieved, and when the gear column is driven in the opposite direction, it will cause the bladder to be expanded upwardly away from the housing to increase the buoyancy while causing the retrieval elements to be retracted around the object and drawn into the housing.

Title: Clamping device for hydraulic-mechanical type tool or work
Inventor: RUDORUFU BURUNAA
IPC: B23Q3/08
Filed: 1987-02-23
Abstract: The invention relates to a hydromechanical tool or workpiece clamping apparatus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.

Title: Optical disc medium
Inventor: MINAMI AKIRA
IPC: G11B7/24015
Filed: 1985-02-28
Abstract: PURPOSE:To attain permanent storage processing of an optical disc after recording by packing a resin to an air gap of sandwich structure so as to prevent contact of direct air to a recording layer of the optical disc. CONSTITUTION:After the end of recording on an optical disc medium B, a resin (e.g., ultraviolet ray curing resin) is packed from a resin injecting hole 16 to preserve the recording. The air in the gap of sandwich structure is deflated by overflowing the resin from a hole 17 to pack the resin, which is cured by irradiating an ultraviolet ray. Since the resin is packed to form an enclosed structure, the rate of a recording layer 7 in contact with air is decreased and the deterioration of the recording layer 7 due to oxidation is prevented. Thus, invasion of air from a bonding face of a spacer and intrusion of water content through the base are avoided in this way, then the disc is used as a permanent storage medium (over 10 years).
