    • Provided is an electric contact member which reduces, to the utmost, peel-off of a carbon film that is caused at the time of use of the electric contact member having at least an edge to keep stable electric contact over a long period of time. Disclosed is an electric contact member which repeatedly contacts with a device under test at a tip part of the electric contact member in which the tip part has an edge, the electric contact member comprising: a base material; an underlying layer comprising Au, Au alloy, Pd or Pd alloy, which is formed on a surface of the base material of the tip part; an intermediate layer which is formed on a surface of the underlying layer; and a carbon film comprising at least one of a metal and a carbide thereof which is formed on a surface of the intermediate layer, wherein the intermediate layer has a lamination structure comprising: an inner layer comprising Ni or Ni alloy; and an outer layer comprising at least one of Cr, Cr alloy, W and W alloy.
    • 提供一种电接触构件,其最大限度地减少在使用具有至少边缘的电接触构件在长时间内保持稳定的电接触时引起的碳膜的剥离。 公开了一种电接触构件,其在尖端部具有边缘的电接触构件的尖端部分处与被测试器件重复接触,该电接触构件包括:基底材料; 包含Au,Au合金,Pd或Pd合金的下层,其形成在尖端部分的基材的表面上; 形成在下层的表面上的中间层; 以及形成在所述中间层的表面上的金属和碳化物中的至少一种的碳膜,其中所述中间层具有层叠结构,所述层叠结构包括:包含Ni或Ni合金的内层; 以及包含Cr,Cr合金,W和W合金中的至少一种的外层。

    • It is an object to provide an engine that makes it possible to constantly detect the number of rotations of a supercharger with a calculation load of an ECU reduced. An engine 1 is provided with an engine base 8 comprised of a plurality of cylinders and a turbocharger 7, a crank angle sensor 4, a turbo sensor 5 that detects rotations of the turbocharger 7 as pulses, an amplifier 11 that divides the pulses by an arbitrary division ratio and calculates the divided pulses, and an ECU 10 that judges a surge condition of the turbocharger 7, wherein the ECU 10 sets a predetermined position of a piston of each cylinder in a crank angle of the engine base 8 to count start timing of the divided pulses, outputs the divided pulses counted from the count start timing to the number of predetermined rotations as a first output, and judges that, if a difference between the first outputs at every cylinder is more than a predetermined value, the turbocharger 7 is in the surge condition.
    • 本发明的目的是提供一种发动机,其能够以减少的ECU的计算负荷来不断地检测增压器的转数。 发动机1设置有由多个气缸构成的发动机基座8和涡轮增压器7,曲轴转角传感器4,涡轮增压器7的旋转作为脉冲的涡轮传感器5,将脉冲除以一个 任意分频比,并计算分割脉冲,以及判断涡轮增压器7的喘振状态的ECU10,其中,ECU10将各气缸的活塞的规定位置设定在发动机基座8的曲轴角度,以计数开始时刻 将从计数开始定时开始计数的分割脉冲输出为第一输出的规定转数,判断为每个气缸的第一输出之间的差大于预定值时,涡轮增压器7 处于喘振状态。
