    • A semiconductor integrated circuit device includes a pulse width expander circuit for expanding the pulse width of a pulse signal of the ECL (emitter coupled logic) level that has a very narrow pulse width, a level conversion circuit for converting the output signal of the ECL level of the pulse width expander circuit into a CMOS (complementary metal oxide semiconductor) level, and an internal circuit that is so connected as to receive the output signal of the level conversion circuit. In other words, the pulse signal having a narrow pulse width is expanded to have a pulse width which is sufficient for the level conversion circuit prior to performing the level conversion operation. Therefore, the level of the pulse signals having narrow pulse widths is stably converted.
    • 半导体集成电路器件包括用于扩展具有非常窄的脉冲宽度的ECL(发射极耦合逻辑)电平的脉冲信号的脉冲宽度的脉宽扩展器电路,用于转换ECL电平的输出信号的电平转换电路 的脉冲宽度扩展器电路转换成CMOS(互补金属氧化物半导体)电平,以及连接到接收电平转换电路的输出信号的内部电路。 换句话说,具有窄脉冲宽度的脉冲信号被扩展为在执行电平转换操作之前具有足够的电平转换电路的脉冲宽度。 因此,稳定地转换具有窄脉冲宽度的脉冲信号的电平。

    • An intermittent swirl type injection valve having a spray angle, capacity coefficient and fuel spray travel distance set so that the valve produces optimum engine operating conditions, with the spray angle, capacity coefficient and fuel spray travel distances being determined taking into account the gap area A.sub.c, the spray hole diameter d.sub.e, and the area A.sub.g of tangential passages in the valve. The injection valve includes a valve body and a valve needle slidably fitted in a valve hole formed in the valve body. A spray hole in the valve body merges with a valve seat provided at an end of the valve hole, and the spray hole is shaped to receive the lower end of the valve needle. Tangential passages swirl the fuel when the needle valve leaves the valve seat to open the valve to spray fuel substantially conically through the spray hole. The injection valve is designed so as to satisfy the following conditions:.alpha.=20.degree. to 75.degree.,d.sub.e =0.3 to 1.2 mm,and ##EQU1## where .alpha. is the spray angle of the fuel and .theta. is the angle between the central axis of the tangential passages and the central axis of the valve needle.
    • 具有喷射角度,容量系数和燃料喷射行进距离的间歇旋流式喷射阀,其设定为使得阀产生最佳的发动机操作条件,考虑到喷射角度,容量系数和燃料喷射行程距离,考虑到间隙面积Ac ,喷孔直径de和阀门中切向通道的面积Ag。 喷射阀包括阀体和可滑动地装配在阀体中形成的阀孔中的阀针。 阀体中的喷孔与设置在阀孔端部的阀座并流,喷孔成形为容纳阀针的下端。 当针阀离开阀座以打开阀门时,切向通道旋转燃料,以通过喷孔大致圆锥喷射燃料。 注射阀的设计是为了满足以下条件:α= 20°至75°,de = 0.3至1.2 mm,而IMA为燃料喷雾角,θ为中心轴 的切向通道和阀针的中心轴线。
