In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.

The present invention provides an inorganic-organic hybrid material having both the characteristics of the inorganic material and the characteristics of the organic material. The material has a lamellar structure formed by piling a sheet of silicon tetrahedrons upon a sheet of titanium octahedrons. In this lamellar structure, an organic group is bonded to a center atom of a tetrahedron via a covalent bond. The organic group can be polymerized to make the organic phyllotitanosilicate a tough and hard coating material. The hybrid material of the present invention thus has both the characteristics, such as high hardness and heat resistance, of the constitutive inorganic material and the characteristics, such as flexibility and filmability at room temperature, of the constitutive organic material, and further has an excellent UV-blocking property.

Disclosed herein is a polyimide composite material which comprises a polyimide-containing resin and a layered clay mineral which is intercalated with organic onium ions and dispersed in the polyimide. Owing to the intercalated clay mineral, the composite material has improved gas and water vapor barrier properties and a small thermal expansion coefficient. Disclosed also herein is a process for producing a polyimide composite material which comprises the steps of intercalating a layered clay mineral with organic onium ions, adding by mixing the intercalated clay mineral to a solution of a monomer or prepolymer for polyimide, removing the solvent, and forming a polyimide. This process makes the layered clay mineral miscible with and dispersible in polyimide.
