Each of the first data lines is disposed upon and insulative to a corresponding second data line, and each of the first and second data lines provides signals to a corresponding pixel electrode.
Abstract:
An easily disassembling cooling apparatus is assembled onto a circuit board. The circuit board has an electronic element. The cooling apparatus includes a pair of fastening blocks, one or two heat conducting blocks, a heat pipe, a fastening plate, and a plurality of locking elements. The fastening blocks are fastened onto the circuit board and each has a track slot. The heat conducting block is installed between the fastening blocks and contacts the electronic element. One end of the heat pipe is installed with the heat conducting block. The fastening plate is installed in the track slots of the fastening blocks, and has a flexible arm that flexibly presses onto the heat pipe. Each of the locking elements respectively is combined with the fastening block. Thereby, the welding process is not required in the assembling process. The electronic element is reliably cooled, and the assembling time is reduced.
Abstract:
An easy LSB tuning method is proposed for a digitally controlled DC-DC converter to increase the DC gain of the digitally controlled DC-DC converter under conditions of no-limit-cycle and a finite bit number to reduce steady-state error of the digitally controlled DC-DC converter. The LSB of one or more of the coefficients in the denominator of the discrete-time domain transfer function of the digital compensator in the digitally controlled DC-DC converter is so tuned that the sum of all coefficients in the denominator of the discrete-time domain transfer function becomes zero. Therefore, the influence of round-off effect on the coefficients of the digital compensator is mitigated.
Abstract:
A reforming system for methanol comprises a reactor and a fuel unit disposed in front of the reactor. The reactor comprises an inlet, an outlet, a reaction chamber between the inlet and the outlet, and a combustion chamber surrounding the reaction chamber. The reaction chamber has a catalyzing unit thereinside. The reactor is constructed for maintaining the reaction chamber at a predetermined temperature so that at least one reactant acts to produce at least one product in the reaction chamber. The fuel unit comprises a first fuel container, a second fuel container, a mixing chamber connected to the first fuel container and the second fuel container, and a nebulizing device connected to the mixing chamber. The reforming system for methanol can produce hydrogen (H2) and the secondary products are recycled.

Abstract:
A method of recycling dummy wafer is provided. The dummy wafer has at least one low-k dielectric material layer formed thereon. A treatment process is performed to the low-k dielectric material layer on the dummy wafer so that a component or impurity in the low-k dielectric material layer reacts to form a volatile substance. A wet etching process is performed to remove the low-k dielectric material layer.
Abstract:
This invention provides an articulated wrench, comprising: a box end; a handle; a fastening device passing through the through holes of the box end and handle; and a flexed spring disc. The fastening device has a head and a shank, wherein the head gradually expands outwards from the shank to form a flared angle having a tapering angle less than 45°. The flexed spring disc is provided in the indent of the box end and flexed along a diameter thereof to form a curvature.
Abstract:
A connector for connecting a tool handle with a tool bit includes a shank, a spring, a detent and a switch. The shank includes a first end, a second end, a non-circular insert formed at the second end for insertion in a corresponding hole defined in the tool bit, a terminal hole extending therein obliquely with respect thereto and a peripheral hole communicated with the terminal hole. The spring is inserted in the terminal hole. The detent is movably inserted in the terminal hole and includes a first end biased by means of the spring and a second end extensible from the terminal hole for engagement with the wall of the hole defined in the tool bit. The switch is connected with the detent through the peripheral hole.
