Abstract: The disclosed refrigeration-cycle equipment comprises a main circuit and an evaporation-side circulation circuit. The main circuit includes i) a compressor that compresses refrigerant vapor, ii) a condensation mechanism that condenses the refrigerant vapor, and iii) an evaporative mechanism that stores refrigerant liquid and that evaporates the refrigerant liquid. The evaporation-side circulation circuit includes a heat exchanger for heat absorption and a decompression mechanism. The refrigerant returns to the evaporative mechanism after the refrigerant absorbing heat in the heat exchanger for heat absorption and the pressure of the refrigerant being reduced in the decompression mechanism. The refrigeration-cycle equipment further has an interaction mechanism that prevents droplets contained in the refrigerant having returned from the evaporation-side circulation circuit to the evaporative mechanism from being fed into the compressor.

Abstract: A process for producing a liner material characterized by dipping a core in the form of a monofilament or multifilament into a vinyl chloride resin sol composition having a thermochromic particulate material incorporated therein, the thermochromic particulate material being prepared by enclosing with the high polymer compound an electron-donating chromogenic substance, an electron-accepting substance for the chromogenic substance and a solvent having a boiling point of at least 150.degree. C. and selected from the group consisting of alcohols, amides, esters and azomethines and further covering the resulting product with a different high polymer compound; withdrawing the core from the sol composition; and heating the core to gel the sol composition and cover the core with the gelled composition.

Abstract: A process for preparing a molded product of thermochromic polyvinyl chloride characterized by incorporating a thermochromic particulate material into a vinyl chloride plastisol comprising a vinyl chloride resin, plasticizer, stabilizer, lubricant and filler, and molding the resulting mixture. The thermochromic particulate material is prepared from particles of a non-thermoplastic resin having encapusated therein the three components of electron-donating chromogenic substance, electron-accepting substance and solvent by coating the particles with a hydrophilic high-molecular-weight compound.

Abstract: A thermochromic composition comprising (1) an electron-donating chromogenic material, (2) a 1,2,3-triazole compound, (3) a weakly basic, sparingly soluble azomethine or carboxylic acid primary amine salt, and (4) an alcohol, amide or ester serving as a solvent.

Abstract: A thermochromatic polyurethane foam comprising a polyol and a polyisocyanate as main components, and a thermochromic composition serving as a coloring agent and added to the main components singly or conjointly with a usual dye or pigment. The thermochromic composition comprises an electron-donating chromogenic material, an acidic substance and a solvent.

Abstract: A transfer printing sheet comprising a base sheet, a releasing resin layer coating the surface of the base sheet entirely or partially, a layer of a pattern printed on the release resin layer and comprising an elastic high-polymer resin and a pigment in admixture, and a layer containing an agent for dissolving synthetic fibers and covering the entire surface of the pattern layer. When the sheet is subjected to heat and pressure, the pattern of the pattern layer can be transferred onto a fabric of synthetic fiber in contact with the layer containing the dissolving agent to give a distinct print having a soft hand and outstanding color fastness against rubbing, washing and light.
