Abstract:
An improved winding structure of a transformer, wherein the transformer comprises a winding base externally set with an isolating plate, the transformer is divided into a primary side region and a secondary side region by the isolating plate. The primary side region has a winding reel for a pre-formed wire set to sleeve on while the secondary side region is divided into a plurality of winding grooves by a plurality of partitions for placing a wire in the grooves, and an iron core set is set on the outside of the winding base and the hollow structure, which altogether form an transformer. In the present invention, an pre-formed wire set is sleeved on a primary side winding reel, therefore, the costs of traditional hand-winding will be displaced, and the manufacturing quality and usage stability of transformers will be effectively improved as well.

Abstract:
The present invention discloses an optical touch control apparatus, comprising: a light guide module having an optical information capturing position, the light guide module guiding light to the optical information capturing position, and generating optical information according to light input through or reflected from the optical information capturing position; and an image sensor module for sensing the optical information, and generating an electronic signal according to the optical information.
Abstract:
A memory card connector includes a housing, a plurality of terminals and a cover. The housing consists of a bottom wall, a front wall, a back wall and a pair of side walls and defines a plurality of slots therein. A receptacle is formed among the walls. The terminals are received in the corresponding slots. The cover is pivotally mounted to the housing, having a top member. At least one pressed component is arranged on the top member. The pressed component includes a pair of opposite spring arms, one end of the spring arms connects with the top member, and the other is stamped individually to form a pair of inclined arms on the top member. The inclined arms joint together by a protruding joint portion, which presses down a memory card. Therefore, a firmly electrical connection between the memory card and the terminals is established.
Abstract:
A carotid pulse measurement device provided for measuring carotid pulse of a user's neck includes a band, an artery-pressing air cell, an inflating/deflating device, and a pressure detection unit. The band functions to surround the user's neck. The air cell is arranged in the band and is fluidly connected to the inflating/deflating device for selectively inflating/deflating the air cell. The pressure detection unit detects variation of pressure inside the air cell. To use the measurement device, the band is put around the user's neck with the air cell positioned exactly corresponding to the carotid artery of the neck so that the pressure detection device detects the pressure variation and generates a digital pulse signal, which is employed to calculate arteriosclerosis index of the user for evaluation the degree of arteriosclerosis of the user.
Abstract:
A crank axle drive structure for a bicycle includes a bottom bracket having inner teeth, a crank axle rotatably mounted in the bottom bracket, at least one drive gear rotatably mounted on the crank axle and meshing with the inner teeth, and a chainwheel fixing seat rotatably mounted on the crank axle and provided with outer teeth meshing with the drive gear. Thus, the inner teeth of the bottom bracket have a tooth number greater than that of the outer teeth of the chainwheel fixing seat, so that the rotation speed of the chainwheel fixing seat is increased, thereby shortening the diameter of the chainwheel so as to perform a pedaling action at the higher rotation speed in an energy saving manner.
Abstract:
A method for exchanging signals with a computer system through a wired and wireless communication in an input device of the computer system includes determining whether the input device connects to the computer system through a wire or not, and exchanging signals with the computer system through wireless communication when the input device cannot connect to the computer system through the wire.
Abstract:
A liquid transportation device includes a working board, a working liquid, a liquid channel and a cover board, wherein the liquid channel is formed on a top surface of the working board, the covering board is fully covered the liquid channel, the liquid channel composed of a material substantially tending to the liquid, and the covering board is composed of a material substantially phobic to the liquid. The working liquid flows within the liquid channel in guidance of the deviation of surface tension between the liquid channel to the working liquid, and the covering board to the working liquid, so that the working liquid is transported within the liquid channel without any external power.
Abstract:
A constant force socket is constructed to include a socket body, which has an inner hole at one end and a set of teeth radially disposed inside the inner hole, a ratchet wheel, which is mounted inside the inner hole of the socket body and has a tool hole at one side and a set of radially arranged teeth at an opposite side, a screw member threaded into the inner hole of the socket body, and a compression spring supported between the ratchet wheel and the screw member to force the teeth of the ratchet wheel into engagement with the teeth of the socket body.
