Abstract: A compressor system includes a compressor and a supply control unit that controls a state of supply of water and a state of supply of oil. The supply control unit includes a rate-of-change acquisition unit that acquires a rate of change in efficiency of the compressor, a supply amount acquisition unit that acquires the amount of supply of the oil, an operating cost acquisition unit that acquires an operation cost from the rate of change, an oil cost acquisition unit that acquires an oil cost from the amount of supply of the oil, and a cost relationship acquisition unit that acquires a plurality of provisional relationship values that are the relationship between the operating cost and the oil cost under each of the plurality of provisional cleaning conditions.

Abstract: An injection molding machine comprises a stationary platen 46 and a movable platen 40. The stationary platen 46 and movable platen 40 may be supported on a base frame 10. A mold clamping frame 56 comprises a first member 54 joined to the stationary platen 46, a second member 24 joined to the movable platen 40, and connecting members 78 and 80 for connecting the first member 54 and the second member 24 at their approximate centers. A mold clamping cylinder 50 is disposed between the first member 54 and the stationary platen 46 or between the second member 24 and the movable platen 40. The stationary platen 46 and the first member 54 are joined in a flexible manner, and the movable platen 40 and the second member 24 are similarly joined in a flexible manner.

Abstract: The present invention enables one hot runner device to be shared between a plurality of molds whose resin inlets are disposed at different positions. This hot runner device discharges supplied molten material to a resin inlet 18b of a mold 18. A hot runner body 42 comprises an inlet opening into which the molten material is supplied, an outlet opening from which the molten material is discharged, and a flow passage. The inlet opening is formed at one end, and the outlet opening is formed at the other end. The flow passage connects the inlet opening and the outlet opening. The hot runner body 42 is driven and moved by a drive mechanism 56 so that the outlet opening 52 can make contact with the resin inlet 18b of each of a plurality of molds whose resin inlets 18b are disposed at different positions. Accordingly, the hot runner device can be commonly used for the plurality of molds whose resin inlets are disposed at different positions.

Abstract: There is provided a resin having a high refractive index. The resin is a polymer comprising units derived from a sulfur-containing unsaturated compound. The present invention also provides novel sulfur-containing unsaturated compounds which in useful in the production of the resin. Examples of these compounds include ##STR1## and CH.sub.2 .dbd.CCH.sub.3 COSCH.sub.2 CH.sub.2 SC.sub.3 H.sub.6 SCH.sub.3.

Abstract: An aqueous slurry comprising fibrous particles of a heat-resistant aromatic polymer and short fibers made of said polymer or insulating inorganic short fibers, or a mixture thereof, is made into a wet web and, after adjusting the water content to 50 to 95 weight %, said wet web is laid up in a desired number of layers, and then the laminate is dewatered and dried for integration under pressure at a temperature not exceeding the softening point of said aromatic polymer, thereby obtaining an oil-impregnatable insulating board with high strength and capable of uniform impregnation of oil therein.

Abstract: A heat resistant thin paper excellent in electrical insulating property can be obtained by subjecting pulp-like particles of aromatic polyamide or aromatic polyamide-imide, which have a low freeness and a low ion content to wet paper-making process, drying and then making the resulting web dense under a pressure.

Abstract: A fibrous sheet having a high strength and water resistance and having no resin specks on the surface can be produced by producing a sheet from a fiber slury by the known paper making process, to said fiber slurry being added a flocculate of chlorinated polymer latices which has a particle size of 100.mu.-500 .mu. and is prepared by heating said chlorinated polymer latices to a temperature of at least their minimum film-forming temperature and then adding a water soluble cationic polymer or a polyvalent metal salt with stirring. Examples of said chlorinated polymer latices are anionic polyvinyl chloride latex, polyvinylidene chloride latex or the combination thereof.

Abstract: A transparent cellulosic paper is produced by coating or impregnating a cellulosic paper with an organic solvent solution containing a compound having a weight-average molecular weight of 200 to 2,000 and having at least two isocyanate groups in a molecule or with an organic solvent solution containing, in addition to said compound, at least one compound selected from the group consisting of an aliphatic monohydric alcohol having 6 to 18 carbon atoms and a nonionic surface active agent to the polyethylene glycol type having one hydroxyl group in a molecule, the ratio OH/NCO in the solution being less than 1; removing said organic solvent; and allowing the coated or impregnated paper to harden by aging.

Abstract: A fibrous sheet bonded with a latex flocculate is produced by adding zinc white powders to a carboxyl modified anionic latex, adjusting the pH to at least 7, adding thereto a water soluble cationic polymer to obtain a latex flocculate, adding thus obtained flocculate to a fiber slurry and subjecting the fiber slurry to a known wet paper making process.
