Abstract:
This is an enhanced thermoelectric cooler with superconductive heat-dissipative coolers for use in air-conditioner. This invention is comprised of a thermoelectric cooling chip sandwiched between two superconductive unidirectional heat-dissipative cooling devices. Each device consists of special superconductive pipes, heat-dissipative plates, and a fan. The cooling devices are to dissipate heat quickly from the thermoelectric cooling chip and to maintain constant hot to cold air flow.

Abstract:
A microphone includes a case, a circuit board, a plate, a cover/button element and an elastic element. The circuit board is disposed in the case and includes a transducer for receiving and converting sound waves into electric signals and a switch operable for turning on and off the circuit board. The plate is disposed in the case and defines two slots and an aperture through which the switch is exposed. A cover/button element includes at least two hooks inserted through the slots defined in the plate so that the cover/button element is movable between a normal position away from the switch of the circuit board and a pushed position in contact with the switch while always covering the case. The elastic element is sandwiched between the plate and the cover/button element for returning the cover/button element to the normal position from the pushed position.

This invention dissipates heat through invented metal pipe materials and formula in single direction to achieve effective cooling result. This invention is to be utilized but not limited to computer Central Processing Unit.
Abstract:
Peel-off nail polish is composed of between 20% to about 30% by weight of Polyacryate, between 8% to about 18% by weight of Plasticiser, between 0.5% to about 5% by weight of Anti-setting agent, and between 60% to about 70% by weight of Solvent. The nail polish can be peeled off easily after drying without the necessity of using nail polish-remover.
Abstract:
A primary functional circuit board with the capability to verify the chip function by an alternative manner and a simplified design for reducing the fabrication cost includes circuit board, chip, verifying apparatus, and extending connection terminals distributed on periphery of the chip. The chip is disposed on the circuit board to execute a functional instruction of the primary functional circuit board. The extending connection terminals are the extension of connection pins of the chip. The verifying apparatus is implemented with a programmable chip having a firmware program needed for controlling the circuit under control. After the verifying apparatus is connected to the extending connection terminals, the switching device is used to select the chip or the programmable chip to control the circuit under control. The engineer can easily compare the difference between the two without a power interruption. The performance and the matching effect can be promptly known, and the desired product can be thereby developed.
Abstract:
A timing adjustment device, method and chip for a bus interface. Through repetitive adjustment of the amount of phase shift in the clocking signal to the bus interface, read/write testing of the bus interface and checking for the correctness of the read/write data, suitability of the phase shift in the memory bus clocking signal for operating normally is determined. Hence, a safety range for the amount of phase shift in the bus interface timing signal is found and the phase shift of the bus interface timing signal is set to the mid-point of the safety range. The method may also be applied to a system bus and the timing adjustment of signals between a control chipset bus and a memory bus.
