  • Patent number: 5494762
    Abstract: In order to improve the charge-discharge energy density of a lithium secondary cell with a nonaqueous electrolyte having such a construction that a metallic compound capable of occluding or releasing lithium is used as an electrode active material, lithium or a lithium alloy is used as a negative electrode material and a solution of a lithium salt is used as an electrolyte, the microstructure of the metallic compound is rendered acicular. Further, a lithium-containing metallic compound grown into such a columnar form that has the angle .THETA. to the normal of the surface of the substrate of< is used as the electrode active material.

  • Patent number: 4843197
    Abstract: A push switch includes a central contact member arranged on a contact support member with an annular peripheral contact member surrounding the central contact member. An elastic conductive member such as a belleville spring and the peripheral contact member along their entire outer edge portions are fixedly held within an insulating case in a manner to seal the space around the central contact. In addition, an elastic spring member may be provided in a position covering the elastic conductive member. A plurality of the push switches may easily be manufactured on an assembly line by forming a multiplicity of central contacts, peripheral contacts and conductive members in separate processes and sequentially going through a first and second insert molding processes.
