  • Publication number: 20210119513
    Abstract: An electric motor includes a frame and a bracket to constitute an outer case, a stator having a cylindrical shape accommodated in the frame, a rotor arranged inner side of the stator, a circuit board placed on a side of the stator which is close to the bracket, a heat-generating component mounted on the circuit board, and a heat sink mounted on the circuit board and thermally connected to the heat-generating component, wherein a first heat-radiating adhesive layer, an insulating sheet, and a second heat-radiating adhesive layer are arranged between the bracket and the heat sink in this order from a side close to the heat sink, and the bracket and the heat sink are thermally connected to each other.

  • Patent number: 7585585
    Abstract: The invention provides a high activity electrode catalyst for fuel cells whose catalytic activity due to an expensive noble metal, such as platinum, has been improved to a higher level through the use of an inexpensive material to enable a reduction in noble metal catalyst usage, a fuel cell in which the above high activity electrode catalyst is used, a membrane-electrode assembly in which the above high activity electrode catalyst is used, and a gas diffusion electrode in which the above high activity electrode catalyst is used.

  • Publication number: 20080076008
    Abstract: To provide an electrode catalyst for a fuel cell comprising inexpensive materials substituting for a precious metal catalyst such as platinum, and a fuel cell using the same. Poly (furfuryl alcohol) containing ferrocene is prepared by dissolving ferrocene corresponding to 1 to 3 wt % on the iron atomic basis in furfuryl alcohol, adding hydrochloric acid (2 mol/dm3) thereto as a polymerization initiator, and then polymerizing them in the air at 70° C. for 48 hours. Random layers 2 developed into onion-like lamination layers around iron particles are produced by heating this poly (furfuryl alcohol) up to 700° C. at a temperature rising rate of 150° C./h, and then holding the state for an hour to carbonize it. The iron carbon complex having this structure of the random layers 2 is applied especially to the cathode side as the electrode catalyst, to form the cells for the fuel cell.

  • Patent number: 4315189
    Abstract: In a color cathode ray tube having a glass envelope and panel, a shadow mask is positioned adjacent a phosphor screen in the panel. Supporting members secure the shadow mask to the panel. These supporting members are responsive to the heat generated in the shadow mask to compensate for the thermal expansion of the shadow mask by displacing the shadow mask toward the phosphor screen. The supporting members each comprise a pair of plate-like segments spaced apart along at least a portion of their lengths. The plate-like segments are formed of metals having different coefficients of thermal expansion. No bi-metallic elements are used to form the plate-like segments of the supporting members.
