Title: Clad material for spectacles frame
Inventor: IWAI AKIRA
IPC: B32B15/01
Filed: 1986-09-19
Abstract: PURPOSE:To improve the high-temp. strength and workability of a product by cladding a Ti sleeve material on the surface of a Ti alloy core material. CONSTITUTION:The core material is formed of the Ti alloy formed by adding one or >=2 kinds of additive elements such as Al, V and Mo to Ti. The Ti alloy core material is clad with the Ti sleeve material, then the stock is extruded by the hot isostatic extruder, thus a wire rod is manufactured. Such a wire rod is subjected to cold drawing, annealing and softening treatment, and cold drawing successively to obtain a Ti-Ti alloy clad wire rod having a prescribed size. Since the Ti alloy material having high strength is used in the core wire part, the core material has the strength and the sleeve material part is made of low-strength Ti to permit the easy plastic deformation thereof. Both the high-temp. strength and workability of the spectacles frame product are, therefore, improved by the above-mentioned method.

Title: Flow amount controller for intravenous drip using flow control element having shape memory feature
Inventor: JIYON EFU KURUMUME
IPC: F16K31/02
Filed: 1983-11-30
Abstract: A unitary disposable conduit extends from the intravenous reservoir along a gravity-flow path to the patient, and incorporates a valve block containing an externally controlled flow-control valve. An electronic controller monitors the drop rate in a drop chamber which is an integral part of the disposable conduit, compares this rate with an operator-selected rate, and controls the valve by varying the current in a shape-memory actuator element whose movements, caused by the resultant Joule heating, are coupled to the valve to proportionally vary the flow rate in the conduit. The valve block is securely received within a recess in the controller, and is automatically coupled to the controller when inserted within this recess. The shape-memory actuator element may be incorporated within the disposable valve block, or may form a part of the controller, with a simple mechanical coupling to transmit its movements to the valve. The valve may be automatically or manually closed when the valve block is removed from the controller, or if power failure occurs.
