摘要： A luminous keyboard includes a light guide layer, a light source, a reflecting layer, a circuit layer, a key fixing plate, mechanical keys, and microstructures. The light guide layer has a first surface, a second surface, and a light incident surface. The light source generates a light beam to the light guide layer through the light incident surface. The reflecting layer is disposed beside the first surface of the light guide layer. The circuit layer formed on the second surface of the light guide layer has multiple switches. The key fixing plate is fixed to the second surface of the light guide layer. The mechanical keys are connected to the key fixing plate, corresponding to the switches, and are pressed to trigger the corresponding switches. The microstructures disposed on the light guide layer surround the switches, and guide the light beam from the light guide layer to the mechanical keys.

摘要： An amplifier includes a sigma-delta modulating circuit, a power stage circuit, two feedback components, an error suppressing circuit, and a selecting circuit. The sigma-delta modulating circuit generates two input voltages according to two input signals or one single-ended signal.

摘要： A heat dissipating module includes thermal conductive pipes and a thermal fin module. The thermal fin module made by pressing and stacking is mounted on the thermal conductive pipes. Next, a jig is set on a top surface of the thermal fin module, and a force compresses the thermal fin module, so as to reduce a distance between two fins of the thermal fin module. Then, a fixing plate is set above the thermal fin module on the thermal conductive pipes, and the jig is removed. Finally, the fixing plate is fixed on the thermal fin module, and the thermal fin module is securely fixed with the thermal conductive pipes. Therefore, the assembled heat dissipating module could not be loosed and deformed during delivery and the engaging contact between the fins and the thermal conductive pipes are enhanced, so to increase the heat dissipating effect of the heat dissipating module.

摘要： A heat dissipating device includes thermal conductive pipes and a plurality of thermal fin modules. Each thermal fin module made by pressing and stacking is mounted on the thermal conductive pipes. A retainer is located between each two thermal fin modules to compress the thermal fin module, so that a distance between two fins of the thermal fin module is reduced. Finally, a fixing plate is set above the last thermal fin module on the thermal conductive pipes to fix the thermal fin modules securely engaged with the thermal conductive pipes. Therefore, the assembled heat dissipating module could not be loosed and deformed during delivery and the engaging contact between the fins and the thermal conductive pipes are enhanced, so to increase the heat dissipating effect of the heat dissipating module.

摘要： An analog-to-digital data converter converts an input signal to corresponding digital signals. The data converter includes two sets of comparison units arranged in an interlaced sense to alternatively analyze the input signal, generate digital signals corresponding to the result of comparing the input signal and reference signals. Each of the comparison units has a positive output and a negative output, and the digital signal is generated by the negative output and the positive output of the comparison units in a differential way. When the comparison units of one set are performing auto-zeroing, the comparison units of the other set perform the data conversion to generate corresponding digital signals.
