Abstract: An electric thermo pot provided with a coating layer formed on the inner surface of the vessel containing powdered charcoal. Electric thermo pot of the present invention improves quality of liquid kept therein. It is generally believed that the liquid quality is improved presumably by infrared ray radiated from the powdered charcoal contained in the layer. Presumable causes for the improvement also include a very small amount of certain elements dissolving out of the powdered charcoal into the liquid and an effect of absorption pertinent to the powdered charcoal.

Abstract: This invention provides a contamination-resistant float glass showing even quality in durability and its good quality sufficienty. The film for contamination-resistance is formed only on the top-side surface of a float glass. The surface, free from tin diffused from a float bath, can be identified by ultraviolet irradation. A solution including a chemical adsorbent like fluoroalkyltrichlorosilane is applied to the top-side surface by a roller coater. The adsorbent can be prevented from hydrolyzing with dry air around the coating portion of the coater. Surplus solution can be removed with dry air blown on the surface to make the contamination-resistant property and the appearance better. The chemical adsorbent is bonded to the surface via a siloxane bond to form a thin film. The contamination-resistant float glass is installed in the front door of an apparatus like a toaster oven with the film facing the inside of the oven.

Abstract: (1) a composition for forming a far-infrared-emitting layer, the composition comprising (i) a liquid composition which contains a ceramics-forming material and which is capable of forming a ceramics layer by gelation induced by polymerization and (ii) at least one pigment capable of emitting far-infrared radiation; and(2) a far-infrared heater comprising a heat source, and a protective means which has a far-infrared-emitting layer formed thereon by applying thereto the composition as defined above in (1) to cause gelation of the coating layer by polymerization.

Abstract: This invention relates to a sheathed resistance heater which comprises a metal pipe (3), a heating wire (2) received in the metal pipe, and an electrically insulating powder (4) filled in the pipe and also to a method for fabricating same. The electrically insulating powder (4) contains 0.1-10 wt % of the specific type of an oxide by which the heater has a prolonged life because the oxide serves to suppress the metallic component of the heating wire (2) from evaporating, and its insulation resistance under self-heating conditions can be prevented from lowering. The heater has wide utility in both domestic and industrial fields.

Abstract: This invention relates to a sheathed resistance heater which comprises a heating wire (2) received in a metallic pipe 3 and electrically insulating powder (4) packed in the pipe. A metallic powder of the specific type is added to the electrically insulating powder (4), by which the heating wire (2) has a prolonged life by suppressing metal components in the wire from evaporating, the heater being widely applicable for domestic and industrial purposes.
