  • Patent number: 5678410
    Abstract: The present invention provides a combined system for activating a fuel cell with hydrogen absorbed and stored in a hydrogen-storage alloy to drive an electric vehicle and for conditioning the air with the hydrogen absorbed and stored in the hydrogen-storage alloy. The combined system of the invention sucks hydrogen out of the hydrogen-storage alloy by a compressor. The combined system of the invention cools the air with a cooling power generated in discharge of hydrogen from the hydrogen-storage alloy and heats the air with a heat generated in absorption of hydrogen into the hydrogen-storage alloy. The combined system preferably includes a heat storage tank disposed in a conduit of a heating medium for storing an excess of a cooling power caused by a variation in an amount of hydrogen required for the fuel cell. Alternatively, the combined system has a secondary battery which is charged with an excess power of the fuel cell and discharges to make up for a deficient power of the fuel cell.

  • Patent number: 5679151
    Abstract: Method of forming a single crystal of ZnSe. A charge of material is loaded in a container. The charge of material is melted to create a melt of material. A single crystal is grown from the melt of material. Then, the grown crystal is brought out of contact with the wall surface of the container. The temperature of the crystal is varied across its phase transition temperature range while establishing a temperature gradient from one end of the grown crystal to the other end. This method is carried out, using a crystal grower comprising the container and an elevation member. The container is disposed inside a high-pressure vessel. The container tapers off downward and is provided with a hole extending from its lower end. The elevation member is inserted into the hole from below to push the grown crystal in a crucible upward.
