Abstract: A radiator bonding to a heat source for transmitting thermal energy includes a conductive base board and a plurality of radiation fins. The conductive base board is in contact with the heat source to perform heat transfer. The radiation fins are mounted onto the conductive base board and are segmented into a first fin section and a second fin section that are spaced from each other at a selected distance to form an airflow space with a wider upper end and a narrower lower end. Airflow generated by a radiation air fan is directly channeled to the conductive base board to perform heat exchange.

Abstract: An electrostatic transmission mechanism can be adopted for use in data media recorders such as printers, facsimile machines, or scanners to transport media. The invention has a feed roller with an electrostatic field generator located therein to generate static electricity on the surface of the feed roller to attract and transport media. The invention can eliminate the disadvantages of conventional transmission mechanisms such as crumpled paper resulting from the pressing of the feed rollers, star wheel tracks on the paper caused by the star wheels, etc.

Abstract: An improved structure of a gear cluster for a bicycle having a crankset mounted with a crankshaft provided with a planetary gear module, wherein the planetary gear module comprises a big wheel and a small wheel section and the planetary gear module drives an inner gear module mounted onto a gear plate; one lateral side of the crankshaft is provided with a driving structure including a second driving wheel and a third driving wheel engageable with the big and small wheel, and the crankshaft is provided with a regulating structure for the positioning of the driving structure and the regulating structure includes two set of a second and a third ratchet block for the positioning or free rotating of the second and the third driving wheel, and the regulating structure is provided with a triggering structure to act on different ratchet block, and the triggering structure makes use of a cable to provide triggering; thereby a gear shift is obtained so as to provide rapid gear shifting and to reduce the force used for

Abstract: The present invention relates to a mounting piece of a disc brake for bicycles which includes a main body and an extension arm at the top of the main body. The extension arm with arched projections has a through hole at both ends thereof, respectively. The main body has a connection recess, thereby creating a restricting wall between the extension arm and the connection recess. The main body further comprises a slide piece laterally disposed at the opening of the rear fork. The slide piece is divided into two parts by an indent with the opening directed downwards. And the slide piece adjacent to the opening of the rear fork has a threaded hole extended to the indent so that adjusting element (or screw) can be screwed into the threaded hole. Accordingly, the disc-brake system is optionally installable to achieve the fine adjustment of the hub axle.

Abstract: A nail pack includes a preset number of T-shaped separate nails, which respectively formed with a sloping insert portion at a lower end of the head. The sloping insert portion has one end formed with a sharp pointed portion of a preset acute angle, and the sharp pointed portion may sink in an upper one of two works to be united by a nail so as to strengthen effectively the tightly uniting force of the nail with the two works. Then the two works are united with better strength more stably.

Abstract: A compact single-stage electronic ballast circuit for emergency lighting applications, integrating the functions of a flyback charger, a flyback discharger and a half-bridge series resonant parallel loaded electronic ballast into a single-stage electronic ballast. The present invention only employs two active switches so as to achieve an electronic ballast for emergency lighting applications when the electricity is out. Furthermore, the present invention reduces the fabrication cost by simplifying the circuit configuration and reducing the number of employed active switching elements.

Abstract: A pressure releasing valve capable of reserving air pressure is formed with a pressure reserving chamber to retain a proper amount of air pressure in the pressure releasing valve when the engine is changing from an accelerating and increasing pressure condition to a condition of running idly and releasing pressure, so that when the engine accelerates and increases pressure again, air of the condenser can be continually supplied for the engine to let it run comparatively smoothly in accelerating, not only economizing energy but ensuring safety as well.

Abstract: The improved structure of bicycle front gearshift module is disclosed. The present bicycle front gearshift module requires no triggering thread device to change gearshift in motionless condition. The present invention has a crank pedestal mounted with a position collar and the inside of the position collar is coupled with a gear axle sleeve, which can move forward and backward. The gear axle sleeve is separately mounted with external gear of different diameter and in conjunction with the crank relative to a planetary gear module, which is mounted with the internal gear of the housing. The external side of the housing is mounted with a gear disc so that a user can directly control the slip motion of the gear axle sleeve in order to change the engagement of the internal and external gear sleeve and the planetary gear module.

Abstract: A one-stage transmissible turbocharger includes a turbine wheel contained in a front current-guider and a rear current-guider, increasing air pressure to elevate horsepower and speeding up burning of gas coming out of a carburetor to save fuel consumption. The turbine wheel has a plurality of leaves respectively helically formed to have 32 angles to make a catch inlet section to elevate air volume to be caught in, and a final axial pressure section for producing centrifugal current so as to give the turbine wheel functions of both axial current and centrifugal current. In addition, the turbocharger has buffer springs for protecting a belt wheel and its bolts from damaged or broken.

Abstract: A shared directory management system includes a storage module, a first cluster server, a second cluster server, and a management module. In the normal mode, the first cluster server controls the storage module, the management module examines the storage module using a monitor method, and if the storage module was processed by an update action, the management module stores update setting information corresponding to the update action into a database. If failure occurs, the second clustered server controls the storage module, the management module returns the storage module according to the update setting information stored in the database, and switches back to the normal mode.

Abstract: It is an improvement of the clutch of the hub of the bicycle. The clutch is made up of the sleeve with attaching holes inside, the spiral connection part formed at the end of smaller diameter with the stair stepping tube, and the screw bar whose end of bigger diameter is the head part; the clutch crosses through the axle inside the hub and uses resisting component made up of the ball bearing that presses the spring to accommodate it in the connection hole of axle, or the leaf spring whose two ends are bent to be elastic clamp end in the distance existing between the axle and sleeve, to produce the clamp and directional function of point contact to the inner wall of sleeve; therefore, at the moment that the freewheel links the head part of screw bar to transmit the kinetic energy, it will not turn in the same direction with the screw bar and can respond to screw forward or backward instantly to decide whether it attaches to the inner wall of hub or not, thus to reduce the friction loss.
