摘要： An amorphous hard carbon film has low friction coefficient from the beginning of sliding, when the metal oxide is contained in the film. The adhesion of the film to the substrate is also improved due to the low temperature treatment of RF plasma enhanced CVD method. This film can be applied to many sliding members, e.g., a piston ring, a vane of compressor and a plunger of fuel injection pump, used under severe condition.

摘要： The MoSi2 heating element has not been so resistant under the low-temperature heating, because the low-temperature oxidation, which is attributable to the grain boundary oxidation, occurred. In the present invention, long life under the low-temperature heating is attained by the following two structures. (1) The MoSi2 grains have a network structure and are linked three dimensionally. (2) The secondary, silica-bearing oxide or glass phase forms a net-like structure around the MoSi2 grains.

摘要： A sliding member used as a sealing ring for a rotary shaft made of a lightweight aluminum alloy in an automatic transmission instead of a conventional cast iron sealing ring in order to prevent leakage of oil and reduce abrasion of the shaft consists of a PEEK resin composition which includes, as binder, 15 DIFFERENCE 20 percent by weight of amorphous alumina powder having an average particle diameter of 5 mu or less, 3 DIFFERENCE 8 percent by weight of graphite powder having an average particle diameter of 5 mu or less and 6 DIFFERENCE 9 percent by weight of carbon powder having an average particle diameter of 30 mu or less.

摘要： A seal ring (20) fitted into a ring groove (4) provided in the outer peripheral surface of a shaft (2) has side surfaces (21a,b) and an inner circumferential surface which receive hydraulic pressure supplied to the ring groove (4). The side surfaces (21a,b) of the seal ring (2) are tapered surfaces so that the width of the seal ring (2) at its inner circumferential surface is smaller than the width of the seal ring (20) at an outer circumferential surface (22) thereof. The outer circumferential surface (22) of the seal ring (20) is arcuate in cross section. Hydraulic pressure which acts upon one side surface (21b) of the seal ring causes the other side surface (21a) of the seal ring (20) to come into sliding contact with the side wall surface (41) of the ring groove (4). As a result, loss torque due to sliding contact is reduced. The tapered surfaces (21a) of the seal ring (20) contact the edge of the side wall surface (41) of the ring groove (4) at all times so that there is no leakage of oil.

摘要： A pressure to resistance transducer or sensor (10) is connected to an amplifier (12). A three-state comparator (14) compares the amplifier output signal with a first reference voltage (15) and its comparison output is looped to another input of the amplifier (12) through a low-pass filter (16). A first controllable current source (41) in series to a first reference resistor (42) is provided in the loop path to detect a break condition of the pressure sensor (10). A second controllable current source (51) in series to a second reference resistor (52) and a voltage divider (54) are also provided in the loop path to detect a short circuit condition of the pressure sensor (10) in combination with the first current source (41). The low-pass filter (16) includes a switch (59) in parallel with a high resistor (58) having its resistance higher than that of a low resistor (17).

摘要： Gas sensor comprises a capture electrode (2) and a platinum counter or reference electrode (3), insensitive to nitrogen oxides, formed on a zirconium dioxide solid electrolyte substrate. A potential difference is measured between the capture electrode and the counter or reference electrode. An alloy electrode made of platinum and rhodium or a cermet electrode made of platinum, rhodium and zirconium dioxide is used as the capture electrode.
