| 20100059963 | DUAL-DRIVE BICYCLE - A dual-drive bicycle has a front wheel provided with a transmission device including: an active sprocket at a top end or another portion of a steering post; a transmission sprocket on one side of an axle of the front wheel; and a chain connecting the active sprocket and the transmission sprocket for power transmission. When mounted at the top end of the steering post, the active sprocket has both ends of its axle extended and equipped with driving handlebars for steering the bicycle and driving the front wheel. When mounted at another portion of the steering post, the active sprocket has one end of its axle extended and equipped with a driving handlebar for driving the front wheel. Thus, in addition to a conventional rear-wheel driving structure, the bicycle has a front-wheel driving device allowing the bicycle to be selectively driven by the rear wheel, the front wheel or both. | 03-11-2010 |

| 20080274377 | Resin artcraft with electric conduction function and method of manufacturing the same - A method of manufacturing a resin artcraft with an electric conduction function includes the steps of: coating an electrically conductive material onto a resin semi-finished good; baking the resin semi-finished good at a predetermined temperature for a predetermined time to form a conductive layer on the electrically conductive material; baking the resin semi-finished good at a predetermined temperature for a predetermined time again after an anti-oxidant material is coated onto the conductive layer, such that the anti-oxidant material is melted with the conductive layer to form an alternate layer, and a portion of the electrically conductive material is permeated into the alternate layer. By baking the electrically conductive material and anti-oxidant material coated separately onto the resin semi-finished good, the conductive layer can be made by using a minimum quantity of electrically conductive material, and the oxidation rate of the conductive layer exposed in air can be retarded significantly. | 11-06-2008 |

| 20090251177 | INJECTION-LOCKED FREQUENCY DIVIDER - An injection-locked frequency divider for dividing a frequency of an injection signal and obtaining a frequency divided signal is provided. The injection-locked frequency divider includes a signal injection unit and an oscillator. The signal injection unit includes a first input terminal and a second input terminal for receiving the injection signal. The received injection signal exhibits a phase difference of 180° between the first input terminal and the second input terminal. The oscillator includes an inductor unit and a variable capacitance unit. The injection-locked frequency divider is featured with a wide injection locking range, and can be realized with a low operation voltage, and therefore can be conveniently used in different kinds of hybrid ICs. | 10-08-2009 |
