20090154075 | FLIP-TYPE ELECTRONIC APPARATUS - An exemplary electronic apparatus ( | 06-18-2009 |
20090158552 | FLIP-TYPE ELECTRONIC APPARATUS - A flip-type electronic apparatus includes a base panel, a cover, and a latch mechanism pivotably fastening the cover to the base panel. At least one post extends from the cover into the base panel. The latch mechanism includes a button mounted on the base panel, and a sliding bar received in the base panel. At least one limiting portion is formed on one lateral side of the sliding bar receiving the post of the cover. The sliding bar forms a pair of inclined operating surfaces, and the button forms at least one inclined actuating surface abutting at least one of the pair of inclined operating surface. When the button is pressed, the actuating surfaces pushes the operating surfaces to cause the sliding bar to move away from the button, and thus the post is released from the limiting portion for opening the cover of the electronic apparatus. | 06-25-2009 |
20090205168 | HINGE ASSEMBLY AND PORTABLE ELECTRONIC DEVICE USING THE SAME - A hinge assembly and a portable electronic device are provided. The portable electronic device includes a lid, a main body, and a hinge assembly. The hinge assembly pivotly connects the lid to the main body. The hinge assembly includes a pivot element, a torsion spring, and a hinge brace. The pivot element is formed on the lid and partially and rotatably received in the main body. The torsion spring is assembled between the lid and the main body. When the lid is in a closed position with respect to the main body, the torsion spring becomes constricted and accumulates potential energy. When the lid is opened from the main body, the potential energy of the torsion spring is released to drive the lid to rotate to an open position with respect to the main body. The hinge brace is attached to the main body for blocking an excessive rotation of the lid with respect to the main body. | 08-20-2009 |
20100008027 | PORTABLE APPARATUS AND POSITIONING DEVICE THEREOF - A portable apparatus includes an electronic device defining a locking slot and a positioning device for detachably attached to the electronic device. The positioning device includes a cover defining an opening and a through hole; a supporting member comprising a hook protruding from the through hole to insert in the locking slot to lock in the electronic device and a supporting portion protruding from the opening of the cover to support the electronic device; and a dampening member fixed to the supporting member in the cover. | 01-14-2010 |

20100122515 | POISON-FILTER MATERIAL AND PRODUCTION METHOD THEREOF - The poison-filter material of the invention includes a substrate and a metal oxide. The substrate includes numerous holes, and the metal oxide is adhered to a surface of the substrate and the holes. The method for producing the poison-filter material of the invention includes the following steps of sonicating and impregnating a substrate into a metallic salt aqueous solution; and calcining the substrate to form a metal oxide on a surface of the substrate and numerous holes of the substrate, such that the poison-filter material is produced. In the invention, the metallic salt aqueous solution is fully oscillated to impregnate the porous substrate, and metal oxide is formed on the surface and holes of the substrate after high-temperature calcination. Therefore, the adsorbent material of the invention can effectively adsorb noxious gas and lower penetrability of noxious gas. During the calcination process, the metallic salt aqueous solution of the invention does not generate harmful volatility solvent such as ammonia. Therefore, the invention can prevent the production process from polluting the environment, harming the health of operator, and reduces the cost for recycling harmful volatility solvents. | 05-20-2010 |

20090070972 | SEMI-AUTOMATIC CLAMP DEVICE - A semi-automatic clamp device includes a tightening mechanism and a connecting rod mechanism. The lowest side of the device is a first workbench having a baffle and supports which connect a passive connecting rod through auxiliary connecting rods. An end of the passive connecting rod connects the baffle through a first spring, and another end connects an active rocker connecting downward on the supports, with another end of the active rocker touching a slide block which connects a slide wheel through a second connecting rod. On a connection point between the second connecting rod and the slide block, the slide block connects tie plates through the first connecting rod transfixing a second workbench having a support bracket. The tie plates connect the support bracket through second springs. This clamp device realizes semi-automatic clamping, improves production efficiency significantly, clamps more securely, and decreases an error in drawing a detection conclusion effectively. | 03-19-2009 |

20100124098 | SRAM AND FORMING METHOD AND CONTROLLING METHOD THEREOF - An SRAM and a forming method and a controlling method thereof are provided. The above-mentioned SRAM includes a tracking column, a normal column, a cell voltage control circuit and a cell voltage pull-down circuit. Each of the tracking column and the normal column includes a plurality of memory cells. The cell voltage control circuit is coupled to the tracking column and the normal column for connecting an operation voltage to the two columns before a write operation of the SRAM starts and for disconnecting the operation voltage from the two columns after the write operation starts. The cell voltage pull-down circuit is coupled to the two columns for pulling down the cell voltages of the two columns after the write operation starts and for ceasing pulling down the cell voltage of the normal column when the cell voltage of the tracking column drops down to a predetermined voltage. | 05-20-2010 |
