  • Multi-layered metal plate with excellent damping capacity
    Publication number: 20020150782
    Abstract: A multi-layered metal plate with excellent damping capacity and particularly, to a multi-layered metal plate with excellent damping capacity and a method for manufacturing it, is less costly since the plate can be simply manufactured by simply attaching a thin plate on a main metal plate by the methods such as welding and the like, has excellent damping capacity and especially can be easily shaped. In addition, in the plate, the secondary plate is attached on one or both surfaces of the main metal plate.

  • FE-base shape memory alloy
    Patent number: 5032195
    Abstract: A Fe-base shape memory alloy consisting of 15-20 wt. % of Mn, not more than 3 wt. % of Si, not more than 10 wt. % of Cr, and the balance being Fe and inevitable impurities is cold worked and heated to 400.degree.-700.degree. C. The Fe-base shape memory alloy of the present invention can be manufactured at low prices by reducing or avoiding the use of high priced elements compared to existing Ti-Ni alloy, and is superior to existing Fe-base shape memory alloy in the shape memory capacity and cold workability.

  • Twin-crank type heat engine
    Patent number: 4683721
    Abstract: A heat engine is provided with twin crankshafts and coil shaped power elements mounted between each of two crankshafts. Each power element moves upward and downward, parallel with the surface of a tank of hot water, in which the engine is partially submersed, so that every part of the power element is allowed to remain submersed in the hot water for the same time interval so as to achieve maximum rotating power.
