Patent number: 6387008Abstract: A speed-changing control mechanism of a multistage speed-changing wheel hub has a planetary gear device comprising a gear support and a plurality of planetary gears. The planetary gears are respectively engaged with a ring gear and sun gears. The rotational power of a drive member is transmitted to the ring gear or the gear support via a sleeve. A speed ratio change is brought about by the action of the planetary gears and the sun gears. The power is finally transmitted to the wheel hub via the gear support or the ring gear. The planetary gears are driven by the power input source portion of the sleeve in conjunction with the action of another sleeve on the fastening shaft, thereby controlling two sets of one-way ratchet pawls opposite in direction to engage or disengage.Type: GrantFiled: September 13, 1999Date of Patent: May 14, 2002Assignee: Industrial Technology Research InstituteInventors: Jia-Lin Chen, Ching-Huan Tseng, Caesar Chen

Publication number: 20010045330Abstract: A bicycle brake shoe, comprising: a support bar; a seat; a brake pad, which is mounted on the seat and for braking pressed against a wheel rim on a contact surface having a front end which faces an opposite movement of the wheel rim; a moving block, mounted on the seat close to the front end of the brake pad, projecting from the brake pad towards the wheel rim, pressed by a spring. The moving block is movable perpendicular to the contact surface of the brake pad and has a projecting surface which upon braking touches the wheel rim prior to the contact surface of the brake pad, scraping water, gravel and dirt from the wheel rim. Thus a braking effect unhampered by water or dirt is achieved.Type: ApplicationFiled: August 7, 2001Publication date: November 29, 2001Inventors: Chung-Ping Chiang, Pai-Hsiang Hsu, Caesar Chen, Ching-Huan Tseng

Patent number: 6113398Abstract: A system (10) for interconnecting two modules (100, 100') to the CUP chip, includes two opposite connectors (12, 14) in a head-to-head arrangement. The traces (200) each of which connects the two corresponding contacts 28/30 and 30'/28' each being located in the same position of the corresponding connector (12, 14), are generally arranged in a parallel relationship. One (12) of the connectors (12, 14) is substantially a standard one. The other (14) of the connectors (12, 14) is generally, but not exactly, of a mirror image with regard to the first one (12), wherein the positions of the two-row contacts (28'/30') with regard to the housing (16') along the lengthwise direction of the second connector (14) are arranged in an opposite relationship with regard to those in the first connector (12).Type: GrantFiled: March 16, 1999Date of Patent: September 5, 2000Assignee: Hon Hai Precision Ind.
