Abstract: A hinge mechanism for pivotally connecting a flip onto a housing includes a bush, a compression spring, and a release button. The bush has a sidewall, a receiving space defined by the sidewall, and a protrusion. The protrusion is protruded from the sidewall. The release button has a shaped notch, which includes a concave portion, a stop portion, and a convex portion formed between the concave portion and the stop portion. The stop portion extends substantially parallel to the pivoting axis. The protrusion is slidably received within the shaped notch. The compression spring is disposed within the receiving space and pressed by the release button and the bush. When closing the flip, the bush rotates synchronously with the flip and the protrusion moves in the shaped notch. When pushing the release button, the flip opens automatically.

Abstract: This invention allows storage electric power to be secured at a maximum by reducing variation in potential between a plurality of capacitors constituting an electric power storage device as follows. A plurality of capacitor banks are provided, in parallel, in the electric power storage device. A part of the respective capacitor banks is halted depending on the current flowing through the electric power storage device.

Abstract: A differential voltage transmission circuit. The reference bias circuit outputs a first reference voltage, a second reference voltage and a reference current corresponding to a reference current adjusting signal. The differential comparator compares the difference between the first reference voltage and the second reference voltage with the difference between a first output voltage and a second output voltage, and outputs a result signal corresponding to the compared result. The decision circuit outputs the reference current adjusting signal corresponding to the result signal. The output circuit outputs the first output voltage and the second output voltage generated at both terminals of a termination resistor when the reference current flows through the termination resistor.

The mounting block has a front, a rear, two opposite sides, two inner guides, defined inside the mounting block and two windows through two corners where the front and the sides of the mounting block meet. The second type connector socket has two indicator lights and two arms. Each arm has a front end and an inclined edge formed at the front end that are held in the corresponding windows. Consequently, light produced by the indicator lights will be transmitted through the arms to the front ends and the inclined edges of the arms. A person can see the light from various directions.

Abstract: Code patterns are first sorted in a codebook in order of power, and catalogued while preparing fixed parameters indicating a selection range size of the code patterns (not greater than values recordable in an analog flash memory), and a variable parameter indicating an offset amount of a selection range, from the leading edge of the codebook. When selecting a waveform, such selection is made from among the code patterns within the selection range, and the selection range is shifted to the optimal position by sequentially renewing the offset amount on the basis of a code number resulting from encoding of a preceding frame, and is then decided upon.

Abstract: A voltage boosting circuit has two charge pumps connected to an output node from which a boosted potential, higher than the power-supply potential, is supplied to a load circuit. One charge pump is activated when the load circuit is activated, regardless of the output node potential. The other charge pump is activated while the load circuit is active, if the potential of the output node falls below a predetermined level. Use of these two charge pumps reduces electrical noise and ensures that the output node is brought to an adequate potential when the load circuit is activated.

Abstract: A heat isolation apparatus is described. The heat isolation apparatus prevents an equipment surface from being heated to a high temperature by a heat source. The apparatus is especially employed for the heat source, such as an integrated circuit, in a notebook computer. The heat isolation apparatus comprises an inlet, an isolation wall, and an outlet. The inlet sucks in fresh air. The isolation wall formed by hollow structure delivers the fresh air to the outlet. The isolation wall separates the heat generated by the heat source on one side and reduces the temperature on the other side thereof. The heat isolation apparatus further connects with a fan. One end, near the fan, of the heat isolation apparatus further has a smooth, curves shape to smooth the floating fresh air.

Abstract: A method for compensating luminance, suitable for use in a plasma display panel. The method includes the following steps. First, the luminance value of each pixel signal is read out. Then, the load of the pixel signal row is computed. The load is the number of pixel signal in the pixel signal row that the luminance value of the pixel signal is larger than a predetermined threshold luminance value. Then, a primary luminance compensation value is decided according to the load of the pixel signal row. A number of secondary luminance compensation values are decided according to the primary luminance compensation value. Afterwards, each pixel signal in the pixel signal row is performed luminance compensation sequentially. If the luminance value is larger than or equal to a low threshold luminance value, the luminance value is subtracted by the primary luminance compensation value.

Abstract: A method for saving register space in a conventional high-level function call process. The method essentially places parameters starting from either of two ends of a sequence of registers for parameter pass, based on data length, thereby reducing register waste and increasing the utility of registers when a function call is coded by a high-level compiler. Thus, the compiler for a high-level program can effectively perform the function call pass.
