  • Patent number: 6698852
    Abstract: A concave design forming unit with the desired form is formed on the surface of a molded component for use in injection molding using a low melting point metal material. An injection molding cavity of the predetermined shape is formed from a metal mold, and after mold curing the molten metal, the molded goods are removed from the injection molding cavity. The injection molding cavity is formed by a first metal mold unit and a second metal mold unit, the metal mold having a trapezoidal concave design forming unit with the predetermined height formed on the metal mold inside surface of the first metal mold unit or the second metal mold unit forming said injection molding cavity. The metal mold is heated to a predetermined metal mold temperature, and the molten metal heated to the predetermined molten temperature will be injected into the injection molding cavity of the heated metal mold at the predetermined injection rate.

  • Patent number: 5360839
    Abstract: Cathodic electrodeposition paints are rendered hardly susceptible to oil droplet-induced craters by incorporating an amine-modified acrylic copolymer of t-butyl (meth)acrylate with a hydroxyl group-containing monomer and an oxirane ring-containing monomer in the form of an aqueous emulsion. The amine-modified acrylic copolymer may be an adduct with a half blocked organic diisocyanate. The paint gives a cured film substantially free from oil droplet-induced craters and having a good adhesion to an overcoating and a good surface smoothness.

  • Patent number: 5250930
    Abstract: A switching apparatus for an electron device, for controlling movement of an image on a display unit, including a plurality of pushbuttons being provided on upper surfaces with directional symbols which represent upward, downward, leftward, rightward directions and random or non-linear paths of travel in which the image displayed is allowed to move. When the pushbuttons are pressed, control signals are transmitted to a control circuit of the electronic device. The pushbuttons with the symbols indicating the four directions are arranged in a cross form, while the pushbuttons with the symbols indicating random and/or non-linear paths of travel are arranged between the pushbuttons forming the cross arms. Further, the pushbuttons with the directional symbols are arranged around a center pushbutton for stopping movement of the displayed image. The pushbuttons are made of a resilient material and assembled as a single unit.
