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.

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.

In a scroll air compressor as a scroll fluid machine capable of being downsized with an increased cooling effect, cooling air entering through a fixed inlet of a fixed cooling passage provided at the rear of a fixed scroll, and an orbiting inlet of an orbiting cooling passage provided at the rear of an orbiting scroll, is allowed to flow out of an fixed outlet and an orbiting outlet, respectively. Thereafter, the cooling air is guided to an outer periphery of the other end of the casing through a side duct and a guide duct, and then sucked into an inner peripheral side of a centrifugal fan to be discharged outwardly from an exhaust port provided in a fan cover.

A scroll fluid machine is capable of readily providing a back-pressure chamber having an increased pressure-receiving area and yet capable of being reduced in size. A fixed scroll member is secured to a casing. An orbiting scroll member is provided at a position facing the fixed scroll member. A holder is provided at the back of the orbiting scroll member, and a coupling member is provided to face the orbiting scroll member across the holder. The coupling member couples together the orbiting scroll member and a driving shaft and performs an orbiting motion together with the orbiting scroll member. A back-pressure plate is provided at the back of the orbiting scroll member, and a back-pressure chamber is formed between the back-pressure plate and the holder.

Disclosed is a method of processing a light sensitive planographic printing plate material comprising an aluminum support, and provided thereon, a photopolymerizable light sensitive layer containing a polymerizable ethylenically unsaturated compound, a photopolymerization initiator, and a polymer binder, the method comprising the steps of imagewise exposing the light sensitive planographic printing plate material, developing the exposed light sensitive planographic printing plate material with a developer to obtain a planographic printing plate, the developer containing no silicate or containing a silicate in amount of not more than 0.1% by weight in terms of SiO2, and plate processing the resulting planographic printing plate with a plate protecting solution containing a phosphonic acid compound at a temperature of from 40 to 90° C.
摘要:
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.
