Patent number: 5134898Abstract: A tactile feedback apparatus, such as for a rotary optoelectronic motion encoder switch, has a ball that successively engages indentations in the surface of a hub. The ball is biased against the hub in a direction at an angle to the perpendicular to the surface by an angled leaf spring. The indentations in the hub are sufficiently deep so that the ball does not contact the floor of any indentation. As the hub wears, the spring inwardly biases the ball to contact the hub at a progressively decreasing radius. Consequently, the useful life of the apparatus is extended, and performance does not significantly degrade during the useful life.Type: GrantFiled: March 7, 1991Date of Patent: August 4, 1992Assignee: Hewlett-Packard CompanyInventor: Eric L.

Patent number: 4941697Abstract: An over-loading idling lock set having an actuating shaft connected to an indoor lock core and an outdoor sealing block wherein the sealing block is connected to an outdoor lock core, and plural ball members pushed by corresponding restricting springs are disposed between the sealing block and outdoor lock core whereby the ball members are partially extended into corresponding restricting holes formed on the sealing block to associate the outdoor lock core with the sealing block. By means of turning an indoor or outdoor handle, the actuating shaft is rotated to open the lock set. When closing the lock set, a controlling bolt is inserted into a longitudinal groove formed on the indoor lock core to lock the same and thus when turning the outdoor handle, the ball members are separate from the restricting holes due to insufficient spring force. Therefore, the outdoor handle can only idle without opening the lock set.Type: GrantFiled: November 28, 1989Date of Patent: July 17, 1990Inventor: Caesar Fan

Patent number: 4922784Abstract: A detent device for a control lever includes a cam which moves integral with a control lever by operation of the control lever. A piston is mounted such that the state wherein the end thereof comes into sliding contact with the cam, during movement of the cam, a pressure chamber is formed to communicate with a part of the piston opposite the sliding surface. A spring is provided within the pressure chamber to bias the piston toward the cam. The cam is provided with a detent portion in a part of the surface with which the piston contacts the detent portion. The sliding resistance of the end of the piston is greater at the detent position of the control lever, than at the other locations. A detector detects that the end of the piston is positioned at said detent portion. An oil-pressure supply device supplies oil pressure to the pressure chamber on the basis of a detection signal from the detector. The detector includes an electric contact constituted by a piston and a cam.Type: GrantFiled: March 2, 1989Date of Patent: May 8, 1990Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Sachio Hidaka, Yoshiaki Fujimoto, Takao Tani
