Title: Thermal energy storage material
Inventor: KIDO TOSHIRO
IPC: C09K5/06
Filed: 1984-10-18
Abstract: PURPOSE:To provide a thermal energy storage material which is effectively prevented from supercooling by addition of a specified supercooling inhibitor in an amt. smaller than in conventional material and retains sufficient thermal energy storing ability in repeated fusion/freezing cycles, prepared by adding the inhibitor to sodium acetate trihydrate. CONSTITUTION:The thermal energy storage material is prepd. by adding 0.0001-10 pts. wt. at least one of sodium sulfite, sodium sulfite heptahydrate, ammonium diphosphate, strontium hydroxide and strontium hydroxide octahydrate to 100 pts. wt. sodium acetate trihydrate. The sodium acetate trihydrate has been found to be the most suitable for a combined heating system such as a heat pump by dint of its high latent heat of fusion, but it has a dis advantage in that it tends to cause supercooling. Addition of the sodium succinate hexahydrate, calcium sulfate dihydrate, etc., has been proposed, but they are not yet in practical use because of their insufficient effect. Addition of the supercooling inhibitor of this invention in a small amt. produces a thermal energy storage material which retains sufficient ability in repeated fusion/ freezing cycles.

Title: Method for jointing ceramic member
Inventor: MURATA KAZUTOSHI
IPC: C04B37/00
Filed: 1992-08-17
Abstract: PURPOSE:To provide a method capable of mutually firmly jointing ceramic members even in the case where the smoothness of the surfaces to be jointed is inadequate, jointing area is large, and such ceramic members are low in mechanical strength. CONSTITUTION:In a method wherein ceramic members 1, 2 are brought into mutual contact through an adhesive followed by heating under pressure, a porous ceramic is used as the adhesive 3. Thus, the porous ceramic, owing to its low mechanical strength at elevated temperatures, can easily be deformed in compliance with the pattern of the surface to be jointed of the ceramic members under a low jointing load. Therefore, even in the case of ceramic members with the surfaces to be jointed uneven, entire jointing can easily be accomplished without large pores left at the jointed interface. Furthermore, since adequate jointing can be attained under low pressing force, easy and efficient jointing cart be accomplished, even in the case of ceramic members with low mechanical strength, without causing damages thereto.
