Title: Photovoltaic power generation system
Inventor: SHINOHARA HIROFUMI
IPC: G05F1/67
Filed: 1987-12-21
Abstract: PURPOSE:To prevent burning of a heat generation part or a fire by detecting ground-fault or short-circuit which occurs in a cable part from a solar battery to a DC/AC inverter and cutting off the route of this ground-fault or short- circuit. CONSTITUTION:A DC contactor 5 is arranged between a solar battery 1 and a cable 4, and the solar battery 1 or a DC/AC inverter 8 is provided with a ground-fault or short-circuit detecting circuit. The DC contactor 5 is turned off at the time of detecting DC ground-fault to cut off the ground-fault route passing the ground-fault point on the cable 4. Since ground-fault, short-circuit, or incomplete short-circuit which occurs in the cable 4 from the solar battery 1 to the inverter part 8 is detected and its accident current is cut off in this manner, burning of the cable 4, a fire in the peripheral part, or the like is prevented.

Title: Heat sink structure of shape memory alloy actuator
Inventor: OHASHI MASAYUKI
IPC: H02N10/00
Filed: 1989-12-13
Abstract: PURPOSE:To promptly lower the temperature of a shape memory alloy after transmitting electricity thereto so as to enhance the reversible response property of the alloy by interposing a ceramics insulator and silicon grease between the shape memory alloy and heat sinks surrounding it. CONSTITUTION:A shape memory alloy 1 is stored in the hollow portion of a silica tube 5 sandwiched between a pair of upper and lower heat sinks 2, 3 via a silicon rubber 4. The space between the shape memory alloy 1 and the silica tube 5 is filled with silicon grease 6. The heat sinks 2, 3 are joined together by thereadably engaging hexagonally-holed bolts 7 in their respective holes 2c, 3c. Heat generated in the shape memory alloy 1 by transmission of electricity thereto is rapidly transmitted to each of the heat sinks 2, 3 via the silicon grease 6, the silica tube 5 and the silicon rubber 4 and is then radiated to the outside. Therefore the temperature of the shape memory alloy 1 is promptly lowered after electricity is transmitted thereto, which increases the reversible response speed of the shape memory alloy as an actuator.

Title: Improvement of residual stress on surface of weld zone of metallic pipe joint
Inventor: TANAKA YASUHIRO
IPC: C21D9/08
Filed: 1987-12-21
Abstract: PURPOSE:To impart a residual compressive stress to the surface at the joint point of a base pipe and branch pipe and to improve corrosion resistance by heating the base pipe and the branch pipe to increase the surface temp. and allowing the pipes to stand by until the internal temp. of the pipe walls attain the temp. adequate for treatment, then rapidly cooling the part near the weld zone. CONSTITUTION:The base pipe 1, nozzle 2 and branch pipe 3 consisting of an austenitic stainless steel are connected via the welded joints 4, 5. Induction heating coils 6, 7, 8 for the base pipe and straight pipe and cooling water ejection headers 9 are wound and disposed respectively to the base pipe 1, the nozzle 2 and the branch pipe 3, respectively. After the inside of the respective pipes 1-3 is made into a hollow state, the respective induction heating coils 6-8 are energized to increase the temp. of the pipe walls. The pipes are then held standing by until the inside temp. of the pipe walls attains about 200-550 deg.C treatment temp. adequate for the treatment. The electric heating is thereafter stopped and the cooling water is ejected from the headers 9 to rapidly cool the outside surfaces of the pipe walls. A difference is thereby generated between the surface temp. near the weld zones 4, 5 and the inside temp. of the pipe walls, by which the residual stress is imparted to the intricate shape part of the joint point.
