Abstract:
A voltage regulating circuit includes a pulse width modulation controller, a current sense circuit, a voltage feedback circuit, and a gain-and-bias circuit. The current sense circuit includes an inductor and a capacitor. The voltage feedback circuit includes first and second resistors. The gain-and-bias circuit includes an operational amplifier. A first terminal of the capacitor is connected to an inverting input terminal of the operational amplifier through a third resistor. A second terminal of the capacitor is connected to a non-inverting input terminal of the operational amplifier through a fourth resistor. The inverting input terminal of the amplifier is connected to an output terminal of the operational amplifier through a fifth resistor. The non-inverting input terminal of the operational amplifier is grounded through a sixth resistor. The output terminal of the operational amplifier is connected to the node between the first and second resistors through a seventh resistor.
Abstract:
The invention provides a protection cover of a pick-up head provided on a traverse of an optical drive. A plate flatly is positioned on an upper surface of the traverse, and the plate has a slot, with one end of the slot fastened to a spindle motor to clamp a disc and the other end of the slot forming a staying part for the pick-up head to stay in a stand-by mode. The pick-up head is disposed in the slot and has an objective lens. When the objective lens stays in the staying part out of a periphery of a 12-cm disc, the protection cover crosses over the staying part to protect the objective lens.

A printed circuit board includes a first signal layer, a first reference layer, a second reference layer, and a second signal layer. An integrated circuit mounted on the first signal layer includes a power supply terminal connected to a first power supply via. The second signal layer includes a filter and a power supply wire. The filter includes a power terminal connected to the first power supply via, and a ground terminal connected to the second reference layer. The first power supply via is connected to the first reference layer through the power supply wire and a second power supply via. A void defined in the second reference layer is at least partially vertically overlapping with the power supply wire, and enables the first reference layer to function as a reference plane for the power supply wire, to increase impedance of the power supply wire.
Abstract:
The present invention provides a direct current generator and a pulse generator thereof. The pulse generator includes a comparator to replace a central processing unit and a logic integrated circuit to save the costs and space required by the electronic components. The pulse generator generates pulses to control the activation of the direct current generator and then to control the output current of the direct current generator. The direct current generator generates current having pulses based on pulses signals from the pulse generator to drive a load.
Abstract:
A process and apparatus of “Solid Oxide Fuel Cell (SOFC)-CO2 Energy Conversion Cycle (referred to as SOFC-CO2-ECC)” are invented to adopt CO2 as energy sources from waste/stock gas or convert and fix it in the useful compounds. CO2 is converted into CO and O2 via simultaneously catalytic and electrochemical reactions in SOFC for power generation and CO2 cracking. Furthermore, CO is used either as the fuel in SOFC for power generation or starting materials in the chemical reactors to produce CO-derivatives of energy source materials and useful chemical compounds. Hence, SOFC-CO2-ECC is an active or scientific carbon cycle with zero emission of CO2. Thus, the efficacy of environmental protection via solving the problem of CO2 greenhouse effect is achieved, so as to grasp of the “Right of Carbon Emission Trading” issues.
Abstract:
In control methods for a multi-function controller, which includes a sensor having a ring operation region, the position of an object on the sensor is detected for generating a position information, and the force applied to the sensor by the object is detected for generating a force information. When the sensor detects multiple successive position information, which indicate that the object is circling along the ring operation region, a rotation information may be generated additionally. The position information, the force information and the rotation information are used to perform operation in various functional modes.
Abstract:
A method of removing a silicon nitride or a nitride-based bottom etch stop layer in a copper damascene structure by etching the bottom etch stop layer is disclosed, with the method using a high density, high radical concentration plasma containing fluorine and oxygen to minimize back sputtering of copper underlying the bottom etch stop layer and surface roughening of the low-k interlayer dielectric caused by the plasma.
