Abstract: A slide bearing device and a compressor are capable of stably achieving a low friction condition from the early stage of the start of friction. The slide bearing device includes a bearing, a shaft supported by the bearing while being subjected to sliding, and a gas supply section for supplying a dry gas to a bearing slide section where the bearing and the shaft slide against each other. A slide surface of the bearing is formed of a resin composite material, which is a mixture of a carbon material and a resin. The shaft is made of a metal and includes a groove formed on a slide surface of the shaft, the groove extending in a direction different from the sliding direction. Plural grooves may be provided and the grooves may extend in arbitrary directions. The shaft may include a collection of plural recesses on the slide surface thereof.

Abstract: The present invention aims to obtain a rotary machine having a function to stably measure an amount of wear of a sliding surface in a sliding bearing with a high degree of accuracy. The present invention provides a rotary machine including: a shaft rotated by torque transmitted from a driving source; a bearing for supporting the shaft; an oil film portion formed between the shaft and the bearing; an ultrasound sensor to propagate an ultrasound pulse toward the sliding surface or the reference step surface provided opposite to the ultrasound sensor installation surface and to receive the ultrasound pulse reflected by the oil film portion; and a diagnostic unit to drive the ultrasound sensor to compare a prestored intensity of the ultrasound pulse in the oil film portion and an intensity of the ultrasound pulse reflected by the oil film portion.

Abstract: To reduce the amount of air leakage from the air cleaner side of the throttle system into the engine side on an occasion where the throttle valve is set to a closed position, a seal material is installed in the air passage that runs from the upstream side of the suction passage, passes through the upstream side of the gap between the shaft and through hole, communicates with the gap formed by the stepped recession, the shaft and the bearing of the throttle body, runs in the circumferential direction of the shaft and through the downstream side of the gap, and reaches the downstream side of the suction passage.

Abstract: To maintain a favorable combustion states, the quantity and quality of a fuel-air mixture to be supplied to cylinders in an internal-combustion engine having multi-cylinder combustors, is where motor-driven fuel spraying mechanisms are provided corresponding to respective cylinders, is controlled with a high response. For this purpose, a mixture supply device has a motor-driven exhaust recirculating mechanism for collecting part of the exhaust generated by combustion in the internal-combustion engine and then remixing the exhaust into the mixture, and an integrated controller for transmitting control signals simultaneously to the above-mentioned three types of mechanisms which are built into a motor-driven multiple-throttle mechanism.

Abstract: To reduce the amount of air leakage from the air cleaner side of the throttle system into the engine side on an occasion where the throttle valve is set to a closed position. The seal material 43 is installed in the course of the air passage that runs from the upstream side of the suction passage 3, passes through the upstream side of the gap 35 between the shaft 7 and through hole 25, communicates with the gap 37 surrounded by the stepped recession 29, shaft 7 and bearing 31 of the throttle body 1, runs in the circumferential direction of the shaft and through the downstream side of the gap 35, and reaches the downstream side of the suction passage 3.
