摘要： A Gray code counter includes a holding circuit, first and second conversin circuit and an operation circuit. The holding circuit stores gray code signals and outputs the stored gray code signals in response to a clock signal. The first conversion circuit receives the gray code signals from the holding circuit and converts the received gray code signals into first binary code signals. The operation circuit applies a logical operation to the first binary code signals so as to generate second binary code signals. The second conversion circuit receives the second binary code signals and converts the received second binary code signals into the gray code signals. The second conversion circuit outputs the gray code signals to the holding circuit.

摘要： In a frame buffer memory including a DRAM (11), an SRAM (12) functioning as a cache memory, and a comparison unit (17) comparing depth data stored in the SRAM (12) and depth data input from an external source and writing depth data input from the external source directly to the SRAM (12) when depth data input from the external source represents a shallower point on a screen, a maxZ detection circuit (27) detecting depth data representing a deepest point among depth data of eight pixels stored in each memory block (18) of SRAM (12) is provided. The detection circuit (27) does not compare depth data of each pixel as comparison unit (17) but detects depth data representing a deepest point among depth data of eight pixels, whereby a Z buffering process is sped up.

摘要： A fuel injection pump of the type wherein the fuel injection timing is controlled by a timer and a solenoid-operated timing control valve. The timer has a high-pressure chamber and a low-pressure chamber which are defined at both sides, respectively, of a timer piston. The high-pressure chamber communicates with a high-pressure groove formed in the timing control valve through a passage. The low-pressure chamber communicates with the suction side of a feed pump through a low-pressure passage and also communicates with a low-pressure hole formed in the timing control valve through a passage. The timer piston is not provided with a passage mechanism which provides communication between a pump chamber and the high-pressure chamber. The pump chamber communicates directly with the high-pressure groove in the timing control valve through a fixed orifice disposed in the wall of the pump housing and a passage leading to the orifice. This structure enables a reduction in the dead volume of the passage required to activate the timer piston.
摘要翻译：一种燃料喷射泵，其中燃料喷射正时由定时器和电磁操作的定时控制阀控制。定时器具有分别限定在定时器活塞的两侧的高压室和低压室。高压室通过通道与正时控制阀中形成的高压槽连通。低压室通过低压通道与进料泵的吸入侧连通，并且还通过通道与定时控制阀中形成的低压孔连通。定时器活塞没有设置有提供泵室和高压室之间的连通的通道机构。泵室通过设置在泵壳体的壁中的固定孔和通向孔的通道直接与正时控制阀中的高压槽连通。这种结构使得能够减少启动定时器活塞所需的通道的死体积。

摘要： In a fuel injection system for an internal combustion engine, a control lever shaft interlocked with a governor spring is supported by a pump housing of a fuel injection pump with one and the other ends respectively located interiorly and exteriorly of the pump housing. A control lever for controlling the fuel injection amount is fixedly mounted on the other end of the control lever shaft. A cancel lever connected to an accelerator pedal through an accelerator rod is freely fitted on the other end of the control lever shaft. The control lever and the cancel lever are disposed to abut against each other on a leading side of the cancel lever with reference to the angular movement thereof in a fuel decreasing direction. A cancel spring is connected between the control lever and the cancel lever to allow them to be angularly moved together. A dash pot for restricting the speed of movement of the control lever in a fuel increasing direction is arranged exteriorly of the pump housing. A synthetic resin bush may be interposed between the cancel lever and the control lever shaft.
