| 20090195953 | Power IC with an over-current protection circuit and method thereof - A power IC with an over-current protection receives an input voltage and converts the input voltage into an output voltage to a load. The present invention controls a power transistor to provide an output current to the load, and uses the output control unit to control the power transistor. Furthermore, the over-current protection circuit has a constant current limit threshold and a fold-back current limit threshold for controlling the power transistor. When the output current is larger than the constant current limit threshold, the output current is clamped to a constant current value to descend the output voltage to a rated value. When the output current is larger than the fold-back current limit threshold, the output current is limited to a low current value to descend the output voltage to zero. Thereby, the inner circuit of the power IC and the load are protected. | 08-06-2009 |

| 20080198537 | Case of extending base for electronic device - A case of an extending base for an electronic device includes a body, a cover, and at least two link elements. The body has a hollow. The cover is disposed aside the hollow. Each link element has a first pivot part, a first block part, a second pivot part, and a first elastic member. The first pivot part has a first end pivoted on the body and a second end connected to the first block part. The second pivot part has a first end pivoted on the cover and a second end connected to the first block part. The first elastic member provides a force to push the first block part from a first position to a second position so as to correspondingly push the cover. Herein, when the first block part is positioned at the first position, the first block part is separated from the body and the cover covers the body. In addition, when the first block part is positioned at the second position, the first block part is in contact with the body and the cover is separated from the body. | 08-21-2008 |

| 20100288014 | Gas sensor and method thereof - A gas sensor comprises a first surface-acoustic-wave device, at least one further surface-acoustic-wave device, and a control device. The first surface-acoustic-wave device includes a piezoelectric substrate, a pair of transducers and an external circuit. The pair of transducers consists of a first transducer and a second transducer, and they are formed on two sides of the piezoelectric substrate. The first transducer is utilized to generate a surface acoustic wave on the piezoelectric substrate. The external circuit electrically connects to the pair of transducers. At least one further surface-acoustic-wave device includes at least one first surface-acoustic-device and a sensing porous thin film of which two sides are formed on the pair of the transducers. The control device is utilized to control only one external circuit to become activated at one time. | 11-18-2010 |

| 20100015026 | Channel-type mesoporous silica material with elliptical pore section and method of preparing the same - A method of preparing channel-type mesoporous material with an elliptical pore section is described. An alkaline solution containing two surfactants different in the electronic properties of their hydrophilic groups is prepared. A silica precursor is added to form a stack of rod-like micelles each having an elliptical section with the silica precursor between the rod-like micelles. The silica precursor is reacted into a silica framework. The rod-like micelles are removed from the silica framework. | 01-21-2010 |
| 20100015027 | Channel-type mesoporous silica material with elliptical pore section - A channel-type mesoporous material with an elliptical pore section has a 2D-rectangular pore arrangement. Besides, the channel-type mesoporous material includes silica and has a unit cell ratio a/b satisfying the inequality of √{square root over (3)} | 01-21-2010 |
| 20100035750 | Carbon-coated metal oxide nano-particles and method of preparing the same - A method of preparing carbon-coated metal oxide nano-particles and carbon-coated metal oxide nano-particles prepared with the same method are described. The method includes the following steps at least. A precursor of a polymer is polymerized on metal oxide nano-particles to form polymer-coated metal oxide nano-particles. Then, pyrolysis is conducted to carbonize the polymer coated on the metal oxide nano-particles, so as to form carbon-coated metal oxide nano-particles. | 02-11-2010 |
