    摘要: The object is to prolong the life of a ball bearing by improving its ability to form oil films. A multitude of needle-like microscopic recesses are formed in a dispersed manner at random in the surface of each ball for a ball bearing. The recesses have a predetermined length and width and are present at a predetermined density so that the surface has a predetermined centerline average roughness.

    摘要: A drive unit for driving an electrically-operated compressor mounted in an automotive vehicle is provided with a ventilation arrangement. The ventilation arrangement includes a casing having a vent hole defined therein. A filter having an air permeability and a water repellency is mounted on the casing so as to cover the vent hole. An elongated ventilation member is mounted on the casing so as to communicate with the vent hole and extends in a direction diverting from the direction in which the casing is splashed with water. The filter may be accommodated in the elongated ventilation member.

    摘要: There is provided a gas concentration-detecting device for detecting the concentration of gas in oil, which is capable of detecting the concentration of gas in oil with accuracy, irrespective of the temperature of oil, and even when oil is degraded. The gas concentration-detecting device includes two electrodes for being arranged in the oil such that the electrodes are opposed to each other and spaced from each other by a predetermined distance, and a capacitance amplifier for outputting a signal indicative of a concentration of gas in oil, the signal being dependent on a capacitance between the electrodes. The predetermined distance between the electrodes is set to a value equal to or larger than a predetermined value at which an amount of drift of the signal output from the capacitance amplifier dependent on variation in a temperature of the oil starts to gradually decrease as the distance between the electrodes is increased.
