Abstract: Disclosed is a method of processing a light sensitive planographic printing plate precursor comprising a support, and provided thereon, a light sensitive layer and an overcoat layer in that order, the method comprising the steps of imagewise exposing the light sensitive planographic printing plate precursor, pre-washing the exposed light sensitive planographic printing plate precursor with a pre-washing solution in the presence of a compound represented by the following formula (1) or (2), or an N-alkyliminodiacetic acid or its salt, the alkyl having a carbon atom number of 1 to 3, and developing the pre-washed light sensitive planographic printing plate precursor with a developer, 1

Abstract: The present invention provides a system of a digital color proof in which consistent images are obtained while minimizing density variation in spite of various variations of conditions due to the use of a silver halide light-sensitive color material, specifically, the present invention provides a method for forming proof images similar to printed images in terms of various characteristics such as the paper quality of silver halide light-sensitive materials, the dot gain, and the density.

Abstract: A scroll fluid machine having a lubrication pump provided between sliding contact surfaces of an orbiting scroll member and a thrust bearing in a casing. The pump has an orbiting member accommodating recess provided in the sliding contact surface of the thrust bearing. An orbiting member projects from the sliding contact surface of the orbiting scroll member into the recess. A slide plate defines a suction chamber and a discharge chamber in the recess. As the orbiting scroll member orbits, the orbiting member orbits in the recess, causing a lubricant contained in the casing to be sucked from a suction passage and delivered to the inside of a boss portion accommodating an orbiting bearing.

Abstract: An effective method of preventing adhesion of scales in service water or circulating industrial water containing calcium carbonate and silicic acid. The treated water is circulated at a flow velocity of more than 0.5 m/sec. through a pipe, and a magnetic field having a magnetic flux density of, for example, 13500 Gs. is applied to the circulating water.

Abstract: A compressor comprises a main compressor body of compressing air, an unloader valve device provided at the suction side of the main compressor body, a bleeding pipe provided between the ejection side of the main compressor body and the unloader valve device, and a controlling valve mechanism provided inside the bleeding pipe. The controlling valve mechanism opens by detecting the fluid pressure at the ejection side of the main compressor body. Further, the unloader valve device has a check valve which opens upon-no-load operation and stopping of the operation of the main compressor body, a main valve which opens due to the air released through the bleeding pipe when the controlling valve mechanism opens, a bleeding passage for releasing the released air supplied to the suction side of the check valve, and a relief passage which communicates when the main valve opens, to release the released air to the suction side of the main compressor body.

Abstract: An oil-cooled compressor including a main body driven by a motor for compressing gas and being cooled by oil, an oil tank for removing oil from the gas compressed in the main body and discharged therefrom, and a suction mechanism for supplying oil from the oil tank and gas into the main body. The suction mechanism includes a suction gas throttling mechanism, operable in response to the pressure of the compressed gas discharged from the main body. The motor is controlled by a temperature switch responsive to the temperature of the oil and a pressure switch which is responsive to the pressure of the compressed gas only at a pressure range which is lower than that of the compressed gas actuating the suction gas throttling mechanism.

Abstract: An oil cooled compressor including a compressor member driven by a motor, an oil tank receiving oil therein and removing oil from the gas discharging out of the compressor member, an oil supplying device for supplying the oil in the oil tank into the compressor member, and a pressure responsive control device for controlling the operation of the compressor member. There are provided a first temperature detector detecting the temperature of the oil, a second temperature detector detecting the temperature of the gas, and a temperature responsive control device restricting the function of the pressure responsive control device in response to the temperatures detected by the first and second temperature detectors.
