Abstract: The present invention is an oval track stepper, which has resolved the disadvantage of a typical oval track stepper by having rear ends of left and right stepping rods linked to left and right sides of a freewheel set and the enclosure, leading to excessive spacing against stepping comfort. The oval track stepper includes a main frame, a head frame, left and right stepping rods, left and right vertical swing rods, a freewheel set and damping device. The freewheel set and damping device are mounted externally at left and right stepping rods. An obstruction-free and closer space between left and right stepping rods delivers an optimum stepping distance for the users, thus improving comfort and practicability.

Abstract: A combination construction for a tip and point ferrule of a billiard cue.

Abstract: A steering mechanism is mainly comprised of an upper and a lower axle seat, in which the upper axle seat and the lower axle seat are provided for receiving an upper axle and a lower axle respectively. The upper and the lower seats are combined together by pivotally jointing each other with a respective inverted U-shaped and a U-shaped pivot-joint ends, where a universal joint having two ends thereof coupled with the upper and the lower axles is arranged in a space enclosed by the pivot-joint ends, so that a diversion may be made by taking the upper axle as a rotation center irrespective of the forward rake or backward rake of the upper axle seat.

Abstract: The present invention provides a module connector including a housing having four sidewalls that define a chamber for receiving a module therein. Each sidewall defines a plurality of contact recesses. A plurality of contacts is accommodated in the contact recesses and electrically contacts with the module. Pull-out prevention slices are positioned on periphery of the housing. Each pull-out prevention slice has a pressing portion which extends into the chamber and presses on the top of the module downwardly, and an actuating portion which extends upwardly from the pressing portion and is adapted for being manually pulled outward. When the module is needed to be pulled out from the module connector, by pulling the actuating portion outward, the pressing portion is driven to move outward and upwardly with the result that the pressing portion departs from the module to make way to the module for the module being pulled out. Therefore, no special tool is needed, in turn, the module is avoided being scraped.

Abstract: A backrest adjustment device includes a bottom board, a support board movable relative to the bottom board, and two opposite linkages pivotally mounted between the support board and the bottom board to drive the support board to move relative to the bottom board to change the distance between the support board and the bottom board. Thus, the two linkages are pivoted to drive the support board to move relative to the bottom board to change the distance between the support board and the bottom board so as to adjust the position of the backrest relative to the seat.

Abstract: A button fastening device with circuit actuating capability includes: a first button part; a second button part engageable releasably with the first button part for fastening articles together; and a circuit actuating unit mounted on at least one of the first and second button parts, adapted to be electrically connected to a circuit, and operable to control circuit states of the circuit through engagement and disengagement of the first and second button parts.

Abstract: A foamed compound for medical articles has ingredients including ethylene vinyl acetate, filler, co-agent, crosslinking agent, blowing agent, and pigment. Wherein ethylene vinyl acetate, the filler, the co-agent, the crosslinking agent, the blowing agent, and the pigment are mixed together in a proper proportion and then foamed. By using foregoing ingredients to manufacture the high density foamed compound, the foamed compound causes no allergic response on the skin and can be applicable to medical articles. Moreover, the foamed compound is non-toxic and can be recycled without causing any pollution.
