  • Patent number: 7628840
    Abstract: Each of the metal nano-particles present in a dispersion, which comprises at least one metal selected from the group consisting of precious metals and transition metals or an alloy of at least two metals selected from the foregoing metals, comprises a metal particle in which an organic metal compound of a fatty acid and/or an amine-metal complex is adhered to the periphery of the metal particle. This organic metal compound and the amine-metal complex are admixed together in a solvent and then the resulting mixture is subjected to a reducing treatment to thus form a dispersion containing metal nano-particles in a concentration of not less than 5% by mass and not more than 90% by mass. The resulting dispersion is applied onto the surface of a base material, followed by drying the applied layer of the dispersion and then firing the dried layer of the dispersion at a low temperature to thus form a thin metallic wire or a metal film having conductivity.

  • Patent number: 7218200
    Abstract: A movable operating member 5 is swingably borne by the base 1, and its distal end is moved upward by allowing its proximal end 5b to be pressed downward. The movable contact 3 is separated from the stationary contact 2 upward by moving the distal end of the movable operating member 5 upward. The proximal end of the movable operating member 5 is pressed downward by a guide pin 6 in response to a reverse action of a bimetal 7. When a reset shaft 8 is pushed upward, the movable contact 3 is pressed upward, and the guide pin 6 is pressed upward so that the bimetal 7 can be returned to an initial state.

  • Patent number: 6835494
    Abstract: By using a rivet which serves also as a terminal member, and a sealing member which serves also as an insulating member, the terminal member and the insulating member can be omitted, thereby forming the lid of the secondary battery from only three parts, i.e. the body, rivet and sealing member. The sealing member includes a cylindrical portion and a flange portion which are separate members. The cylindrical portion is formed by cutting a fluororesin tube. The flange portion is formed by punching a polypropylene resin sheet. Thus, the number of parts can be reduced to four, so that it is possible to reduce the parts cost and manufacturing cost as compared to conventional lids.
