| 20100176778 | AUTOMATIC VOLTAGE-IDENTIFYING POWER SUPPLY DEVICE AND METHOD THEREOF - An automatic voltage-identifying power supply device has a control module, a voltage regulation circuit, a current load measuring circuit electrically connected with an external post-stage power-receiving device, a power supply circuit and a pre-stage power supply device. After the post-stage power-receiving device is electrically connected with the current load measuring circuit, the control module can control the voltage regulation circuit to output a test voltage signal to the post-stage power-receiving device so that the test voltage signal is altered according to a preset sequence (e.g. progressively increasing) and the current load measuring circuit measures a response current signal of the post-stage power-receiving device corresponding to the test voltage signal. When a variation of the response current signal or a power variation is stable, the control module sets up the stable test voltage signal as an input voltage to the post-stage power-receiving device. | 07-15-2010 |

| 20110085382 | Universal dual charge-retaining transistor flash NOR cell, a dual charge-retaining transistor flash NOR cell array, and method for operating same - A NOR flash memory cell is formed of dual serially connected charge retaining transistors. A drain/source of a first of the dual charge retaining transistors connected to a local bit line and a source/drain of a second of the dual charge retaining transistors connected to a local source line. The drain/sources of the commonly connected dual serially connected charge retaining transistors are connected solely together. The drain/sources and source drains are formed in a diffusion well. In some embodiments, the diffusion well is formed in a deep diffusion well. The dual serially connected charge retaining transistors are N-channel or P-channel charge retaining transistors with the charge retaining layers being either floating gate or SONOS charge trapping layers. Selected charge retaining transistors are programmed by a combination of a band-to-band tunneling and a Fowler-Nordheim tunneling and erased by a Fowler Nordheim tunneling. | 04-14-2011 |

| 20100295318 | WIND-POWERED ELECTRICITY GENERATOR - A wind-powered electricity generator has a supporting tube, a rotating device, a drive device, a mounting frame, a guiding board and two fan bodies. The rotating device is rotatably mounted on the supporting tube and has a mounting tube, a top cover and a transmitting shaft. The drive device is mounted in the supporting tube and is connected to the transmitting shaft. The mounting frame is securely mounted on the mounting tube and has a spindle, a gear wheel and a dynamo. The guiding board is connected to the mounting frame, faces the wind in used and has multiple spindle rings, multiple pivotal panels, multiple linking arms, a driving shaft and an expansion device. The fan bodies are rotatably mounted around the spindle in the guiding board and each fan body has a central axle, multiple connecting tubes, multiple blades, two annular frames, multiple cross bars and multiple pull bars. | 11-25-2010 |
| 20110148120 | WIND-POWERED DEVICE - A side-blown wind-powered device has at least one blade driven by the wind power and moving along a track. With the movement of the blade, the wind power can be efficiently transferred into a mechanical power to drive electrical devices or generate electrical power with generating devices. | 06-23-2011 |

| 20090139283 | HIDDEN LOCK LOCKED TO AN INNER SIDE OF A DOORPLATE - A hidden lock locked to an inner side of a doorplate comprises a top seat assembly; a top rod; the top seat assembly being assembled to the top rod; a linking rod installed to a lower side of the top rod; a lower rod; a lower head; a top seat assembly; a resisting unit. The connecting shaft having a groove, plurality of slots, a plurality of holes, an upper engaging tube and a lower engaging tube. A bent stop is extended from the resisting unit. When a top rod reduces inwards, the stop will resist against a neck of the top rod to prevent a lower head to contact the ground. A pin device is installed for retaining the lock in high temperature. | 06-04-2009 |
| 20090183538 | FIREPROOF DOOR LOCK - An fireproof door lock comprises a handle seat frame being a U shape frame; a press unit installed in the U shape frame of the handle seat frame; the press unit having a driven mechanism; the driven mechanism including a driven unit; a plurality of buckling units, an elastic unit, at least one vibration reduction element, at least one driving bodies, a bottom plate and a pin unit; a press element having an L shape and being attached to the driving body by using a plurality of studs passing through a connecting unit, the press element and a driving unit; and fireproof door lock installed at a front end of the fireproof door lock; so that the driven mechanism of the press unit having the effect of opening the fireproof door look. | 07-23-2009 |
