Abstract: A dew condensation detecting device includes a dew condensation detector and a heat transfer part. The dew condensation detector is provided to a supply pipe, which supplies a cooling medium from a cooling medium supply apparatus to a device to be cooled. The dew condensation detector detects a dew condensation by detecting a water droplet due to the dew condensation. The heat transfer part transfers heat from the cooling medium flowing in a return pipe, which returns the cooling medium from the device to be cooled to the cooling medium supply apparatus, to the cooling medium flowing in the supply pipe between the dew condensation detector and the device to be cooled.

Abstract: A second housing whose center portion is depressed and whose end portion around the center portion is formed like a visor is arranged around a first housing whose center portion is depressed and whose end portion around the center portion is formed like a visor, and a hollow portion is formed between the first housing and the second housing by sandwiching a packing between the end portions of the housings. Further, degassed water for preventing empty heating is filled in the hollow portion, and an ultrasonic transducer is placed on the surface of the center portion of the first housing. A weight for preventing the vibration of the wall is provided on the wall surface of the second housing. Since the vibration of the wall of the housing is suppressed by the weight, vibration energy returns toward the bottom surface of the center of the housing through water and is radiated from the bottom surface efficiently as ultrasonic waves.

Abstract: A substrate cleaning method and an apparatus therefor capable of increasing a particle removal ratio at which particles firmly adhering to a substrate are removed therefrom and increasing a throughput. A substrate such as a wafer or the like placed in a cleaning tank filled therein with a cleaning liquid is cleaned by an ultrasonic vibration. Cleaning of the substrate is carried out in such a manner that an ultrasonic vibration is applied to the substrate from a bottom of the cleaning tank, during which application the substrate is kept at a predetermined inclination angle with respect to a direction of acoustic streaming in the cleaning liquid formed by propagation of an ultrasonic wave.

Abstract: An ultrasonic vibrating apparatus and an ultrasonic cleaning apparatus capable of permitting ultrasonic cleaning of a wafer to be carried out using an existing cleaning tank and while keeping the object immersed in cleaning liquid. An ultrasonic wave is irradiated to a cleaned object while keeping it immersed in cleaning liquid stored in a cleaning tank formed with an upper opening. A vibrating plate is securely mounted thereon with an ultrasonic transducer through a wave transmission element and arranged so as to close the upper opening of the cleaning tank in a cover-like manner. The vibrating plate is so arranged that a vibrating surface thereof downwardly faces and is immersed in the cleaning liquid.

Abstract: While a crawler body 110 is traveling, infrared sensors 144 and an elevational difference calculator 132 incorporated in a controller 130 detects the magnitude of a step present ahead of the crawler body 110. A safety speed calculator 134 calculates a safety speed based on the magnitude of the step detected and on the position of the platform 116 relative to the crawler body 110, which position is detected by various detectors 141˜143 and by a position calculator 133. A comparator 135 compares this safety speed with the traveling speed of the crawler body 110, and if the current speed of the crawler body 110 is greater than the safety speed, then the comparator 135 outputs a warning signal. Upon receiving this signal, a restrictor 136 controls a valve controller 131 to reduce the speed of the crawler body 110 such that the crawler body 110 can travel over the step safely.

Abstract: An ultrasonic shower cleaning apparatus includes a casing, a nozzle mounted to the downstream end of the casing, a substantially circular ultrasonic transducer operable to emit ultrasonic waves and oriented to face the upstream end of the nozzle, and an inlet port formed in the periphery of the casing to receive a cleaning liquid. The nozzle includes a right circular cylindrical outlet port through which the cleaning liquid along with the ultrasonic waves are released so as to ultrasonically clean an article. The outlet port extends axially through the nozzle and has a fixed diameter. The upstream end face of the nozzle is cone-shaped so as to be tapered in a direction toward the downstream end of the nozzle from its outer edge to the outlet port at a predetermined angle of inclination.
