Patent number: 6222527Abstract: A key structure comprises base plate, elastic member, frame and cap wherein the conductive membrane thereof is single-film structure, the contact of the conductive membrane corresponding to each key is of meshed-hook shape (), a venting aperture is provided at the center of the contact. A transparent and insulating layer is arranged upon the conductive membrane to prevent the short circuit of the circuit in the conductive membrane. An opening is provided at the transparent and insulating layer and corresponding to the conductive membrane. Both ends of the elastic member are attached to the cap and the transparent and insulating layer by adhesive. A conductive bump with a conductive layer is provided on the elastic member such that the conductive bump of the elastic member is connected to the contact of the conductive membrane and a closed loop is formed within the key when the cap is pressed down, whereby the signal generated by key stroking action is transmitted to the computer.Type: GrantFiled: January 6, 1999Date of Patent: April 24, 2001Assignee: Silitek CorporationInventor: Gino Hu

Patent number: 6191776Abstract: A compact key structure comprises a base plate, a conductive membrane, an elastic member, a frame and a cap wherein said key structure is characterized in that the conductive membrane is single-film structure and has a contact corresponding to each key and with meshed-hook shape . An aperture is provided at the center of the contact for venting air. The elastic member and the cap are attached by a non-reactive type paste such that the elastic member and the cap can be attached and separated repeatedly. The surface of said elastic member attached to said cap is of staircase shape and has venting holes formed on the lateral side to facilitating the restoring of the elastic member after being pressed. Moreover, a conductive bump is provided within the elastic member and corresponding to the conductive membrane. A conductive layer is formed on the conductive layer and corresponding to the contact of the conductive membrane.Type: GrantFiled: January 6, 1999Date of Patent: February 20, 2001Assignee: Silitek CorporationInventor: Gino Hu

Patent number: 6179497Abstract: A keyswitch for notebook computer comprises at least a keytop, a rubber cone, a base, a bottom plate below the base and two levers arranged in scissors form between the keytop and the base. The upper ends of the two levers are connected to the keytop and the lower ends of the two levers are provided with pivotal shafts. The pivotal shafts on the both lower ends of at least one lever is projecting from an outer wall of the lever such that a dent is formed between a rear wall of the pivotal shaft and a bottom end of the lever. The base has a plurality of through holes corresponding to the pivotal shafts on the both lower ends of the levers and the pivotal shafts are pivotally engaged with the through holes. A clamping plate arranged atop each the through hole. The base has a hollow accommodating space below the two levers. The bottom plate has a plurality of through holes corresponding to the pivotal shafts on the both lower ends of the levers.Type: GrantFiled: November 5, 1999Date of Patent: January 30, 2001Assignee: Silitek CorporationInventor: Gino Hu

Patent number: 6160233Abstract: A key structure of computer keyboard having a base, a conductive film, an elastic member, a frame, a cap. A plurality of coupling parts are arranged on the cap and the base, wherein the coupling part on along the same side of the cap and the base are composed of a sliding groove and three fixed grooves. The frame has a plurality of pivoting shafts arranged within the sliding grooves and fixed groove such that the frame can be pressed down. Both sides of the elastic member are fixed between the cap and the conductive film such that the elastic member will not outleap. A clamping device is arranged between the cap and the base such that the key will not shake when being pressed.Type: GrantFiled: December 18, 1998Date of Patent: December 12, 2000Assignee: Silitek CorporationInventor: Gino Hu

Patent number: 6091036Abstract: A keyswitch is provided that comprises a key top, a rubber cone, a first lever, a second lever, and a base. An operation surface and an assembly surface respectively form at the top end and the bottom end of the key top. A penetrating accommodation room is installed on the base. The rubber cone is installed between the key top and the base. The first lever and the second lever are installed between the assembly surface of the key top and the base. The two levers are in scissors arrangement. The top ends of the two levers are connected to the assembly surface of the key top. The bottom ends of the two levers are connected to the base. The accommodation room is disposed below the two levers. A bottom board is installed at the bottom of the base. When the two levers are jointly moved downwards via the key top, they can sink into the accommodation room. A low-profile keyswitch can be acquired under the condition of the same key pressing stroke. The compactness requirement of modern products can thus be achieved.Type: GrantFiled: October 18, 1999Date of Patent: July 18, 2000Assignee: Silitek CorporationInventor: Gino Hu
