A compressor control method of controlling the vibration amplitude of a compressor equipped with a motor by using the motor is provided. The compressor is driven by the motor, and this method includes controlling, in a specific operating area, the vibration amplitude of the compressor such that the vibration amplitude is substantially constant regardless of changes in the load imposed on the motor and in the number of revolutions of the motor per unit time.

Compressor control method

Provided is a resin composition that will suffer from little drop of lubricity and will offer good touch feeling even if it is used repeatedly. A resin composition superior in lubricity and touch feeling is produced by melt-mixing a water-soluble polyethylene oxide having a viscosity average molecular weight of 1,000,000 to 6,000,000, a modified polyalkylene oxide obtainable by reacting a polyalkylene oxide, a diol compound, and a diisocyanate compound together, and a thermoplastic resin together.

Resin composition whose lubricity under wet conditions is maintained

The present invention provides a cosmetic composition that is stable, not sticky when used, has excellent moisture and smoothness, and maintains the effects for a long time without deterioration due to washing and/or sweating. Specifically, the present invention provides a cosmetic composition that comprises: (i) a polyalkylene oxide-modified product obtained by reacting a polyalkylene oxide compound, a diol compound, and a diisocyanate compound; and (ii) water or a lower alcohol aqueous solution, wherein the cosmetic composition comprises 0.3 mass % or more polyalkylene oxide-modified product.

Cosmetic composition

A hydrophilic thickener comprising a polymer obtainable by subjecting a water-soluble ethylenically unsaturated monomer to a reversed phase suspension polymerization in the presence of a polyoxyethylene polyoxypropylene alkyl ether; and a cosmetic composition containing the hydrophilic thickener. The hydrophilic thickener according to the present invention can be used in the fields of cosmetics such as powder foundations, liquid foundations, emulsions, lotions, liquid cosmetics, moisturizing gel, all-in-one gels, cleansing foams, hair setting agents, emollient creams; toiletries, sundries, and the like.

Hydrophilic thickener and cosmetic composition

The present invention provides a lubricating resin composition for personal care, wherein the composition not only maintains its excellent lubricity and roughness-resistant property under a wet condition even during repeated use thereof, but also represents a low swelling ratio and no slimy feeling under a wet condition. The lubricating resin composition for personal care Of the present invention comprises 100 parts by mass of a water-absorbent modified polyalkylene oxide and 25 to 500 parts by mass of a low-melting point polyamide resin.

Lubricating resin composition

The present invention provides a water-soluble polyalkylene oxide-modified product which is nonionic, has a high thickening effect and is also excellent in transparency, and an emulsion composition and a cosmetic material containing the same. More specifically, the present invention provides a water-soluble polyalkylene oxide-modified product obtained by reacting a monovalent hydrophobic alcohol, a linear diol compound, a polyalkylene oxide compound and a diisocyanate compound, and an emulsion composition and a cosmetic material containing the same.

Water-soluble polyalkylene oxide-modified product

The object of the present invention is to provide a modified polyalkylene oxide capable of yielding an aqueous solution excellent in transparency with high viscosity, even when combined with a cationic surfactant. The present invention provides a modified polyalkylene oxide obtained by reacting a polyalkylene oxide compound (A), a polyether monohydric alcohol (B), and a diisocyanate compound (C);

Modified polyalkylene oxide

The present invention provides a sheet that has excellent lubricity and good touch feeling under wet conditions and suffers from little drop of the lubricity even if the sheet is used repeatedly. In the sheet of the present invention, a layer of modified polyalkylene oxide obtainable by reacting a polyalkylene oxide compound, a diol compound, and a diisocyanate compound together is directly formed on a surface of a substrate.

Sheet whose lubricity is maintained under wet conditions

An improved process for the production of a water-absorbent resin by reversed phase suspension polymerization of a water-soluble ethylenic unsaturated monomer is disclosed. The process is conducted by subjecting an aqueous solution of a water-soluble ethylenic unsaturated monomer to reversed phase suspension polymerization reaction of a first stage in a petroleum hydrocarbon solvent in the presence of a surfactant and/or polymeric protective colloid by using a radical polymerization initiator optionally in the presence of a crosslinking agent, cooling the resulting slurry to precipitate the surfactant and/or polymeric protective colloid, and adding an aqueous solution of a water-soluble ethylenic unsaturated monomer containing a radical polymerization initiator and optionally a crosslinking agent to the first polymerization reaction system to further carry out the reversed phase suspension polymerization reaction, at least, once.

Process for production of water-absorbent resin

A scroll type fluid apparatus having a rotation preventing mechanism provided with a sliding member engageable with the outer surface of a bearing portion at an orbiting scroll and regulating the radial movement of the sliding member in reciprocating movement, and a sliding member holder engageable with the outer surface of the sliding member so as to regulate the movement of the sliding member in the direction perpendicular to the moving direction of the bearing portion. Spaces formed before and behind the sliding member in the sliding direction thereof are utilized as oil chambers respectively, whereby lubricating oil pumped-up from an oil pickup provided at a crankshaft is forcibly fed by the pump action caused by sliding motion of the sliding member onto the slidable contact surface of a thrust bearing supporting the orbiting scroll.
