Abstract:
An electrical connector includes an insulative housing and a pair of contacts. The insulative housing defines a mating face, a rear face opposite to the mating face, and a receiving cavity between and running through the mating face and the rear face. The contacts are retained in two opposite sides of the receiving cavity and each defining a contacting portion, a retaining portion extending backward from the contacting portion and at least a terminal portion extending from the contacting portion. A pair of elastic pieces integrally extend backward from the mating face of the insulative housing to the receiving cavity and free ends of the contacting portions resist on the elastic piece. The elastic pieces shift away from the receiving cavity under a condition that a mating electrical connector is inserted in the receiving cavity and press against the elastic pieces. The contacts are wider than the elastic pieces.
Abstract:
An electrical connector includes an elongated insulative housing and a plurality of terminals retained in the housing. The housing defines a mating face, a rear wall opposite to the mating face, two slots opening to the mating face and arranged side by side. A plurality of terminals are secured in the insulative housing. Each terminal defines a contact portion exposing to the corresponding slot. A latch integrally extends from the rear wall forwardly and is located between the two slots, the latch has two arms separated by a groove thereby providing resiliency.

Abstract:
A reference leak (10) includes a first substrate (20), a second substrate (40) disposed and bonded on the first substrate, and predetermined numbers of leak channels (14) defined in at least one of the first and second substrates. Oblique walls of the leak channels are formed by crystal planes of the at least one of the first and second substrates, the oblique walls thereby being aligned according to such crystal planes. A method for making a reference leak is also provided.
Abstract:
An exercise device includes two cranks rotatably coupled to an upright support of a base, two handles pivotally coupled to the upright support, and two foot supports each having a front portion pivotally coupled to the pivot rod or an extended arm of the cranks with a link and each having a rear portion pivotally coupled to the rear portion of the base, and the lower portions of the handles are pivotally coupled to the foot supports to allow the moving stroke of the foot supports to be controlled by the handles. The handles may be pivotally coupled to the cranks with levers. A foot pedal may be pivotally supported on each of the foot supports and pivotally coupled to the handles.
Abstract:
An ionization vacuum gauge includes a cathode electrode, a gate electrode, and an ion collector. The gate electrode is disposed adjacent to the cathode electrode with a distance therebetween. The ion collector is disposed adjacent to the gate electrode also with a distance therebetween. The cathode electrode includes a base and a field emission film disposed thereon facing the ion collector.
Abstract:
A riding device includes one or more cranks rotatably attached to a base, and a rider support supported on a carrier and movable relative to the base for supporting a rider, and a moving device for moving the carrier and the rider support relative to the base in an elliptical and reciprocating action, the rider support may be moved in different moving strokes relative to the base and may be adjusted up and down relative to the carrier. The base includes a column having a pivotal arm coupled to the carrier with a link for allowing the carrier and the link to be moved up and down relative to the base and for allowing the carrier and the rider support to be moved in different elliptical and reciprocating actions by the crank.
Abstract:
A CNT field emitting light source (20) is provided. The light source includes an anode (202), an anode substrate (201), a cathode (214), a cathode substrate (208), a fluorescent layer (203) and a sealing means (205). The anode is configured on the anode substrate, and the cathode is configured on the cathode substrate. The anode and the cathode are oppositely configured to produce a spatial electrical field when a voltage is applied therebetween. The cathode includes an emitter layer (206), capable of emitting electrodes bombarding the cathode and matters attached thereupon when activated and controlled by the spatial electric field, and a conductive layer (207), sandwiched between the cathode substrate and the emitter layer for providing an electrically connection therebetween. The fluorescent layer is configured on a surface of the anode oppositely facing the emitter layer, so as to produce fluorescence when bombarded by electrodes emitted from the emitter layer.
Abstract:
An electrical connector (1) includes an insulative housing (2) defining a mating face (200) thereof. First and second terminals (3, 4) have the same-length received section (30, 40) in the respective passageways, and a leg section (31, 41), wherein the received section (40) of the second terminal (4) extends much closer to the mating face (200) than that of the first terminal (3). The leg section (41) of the second terminal (4) has a transition section (411), and a tailing section (410) located with a same distance away from the mating face (200) with that of the first terminal (3). This configuration of the first terminals (3) and the second terminals (4) can be set on a same carrier tape (6) to be assembled onto the insulative housing (2) in a common working procedure, which will reduce the operation time and manufacturing costs.
