  • Patent number: 6308961
    Abstract: A purpose of the invention is to provide a gasket in use for HDD unit wherein a spatial continuity conducted from an interior of an HDD unit to an external open ambient for generating a leakage is prevented as well as an integrated manufacturing of a cover and a gasket member into a single constituent that has so far been separated into two constituents in a conventional structure, thereby not only reducing a number of assembly steps but also rendering manufacturing procedures easier that are attained by the present constitution, wherein: the gasket formed of an elastic member 3 is embedded in a base cover 1 formed of a stainless steel and included in a through-hole 2, which is opened on a desired portion of the base cover and penetrates from an internal surface to an external surface of the base cover, to be protruded further internally from the internal surface of the base cover as well as to be protruded further externally from the external surface of the base cover, thereby to seal an entire interior of t

  • Patent number: 4983787
    Abstract: The coordinate input unit is provided with a coordinate input pad in which one or more pairs of sheet-like electrodes for a function switch held by a pressure-sensitive electroconductive sheet having weighed input sensitivity different from that of another pressure-sensitive, electroconductive sheet, is laminated on a pair of flexible, sheet-like electrode groups for coordinate input having a plural number of electrodes in accordance with the pressing position, and which is held by the latter pressure-sensitive, electroconductive sheets. The described coordinate input unit allows to perform several input operations of coordinate input and using several function switches using only one hand.

  • Patent number: 4914416
    Abstract: A pressure-sensing electric conductor, has an elastic electric conductive layer made of silicone rubber, on which a flexible insulating layer made of resin having a number of holes in a form of net pattern is overlaid. The pressure-sensing electric conductor is produced by applying a silicone adhesive compound to which toluene and silicone ink are added over the flexible sheet of resin insulating layer having a number of holes, and adhering said sheet to said electric conductor formed by means of vulcanization into an elastic sheet, and by bonding them together by applying pressure to both sides of the resin insulator and electric conductor.
