Filed: 1992-11-24
Abstract: PURPOSE:To equalize, by means of simple method, the temperature of fluid in a thermal insulating container made up by filling spaces surrounded by inner and outer covers with thermal insulating materials, and to prevent incoming and outgoing of heat to and from the container by a method wherein thermal insulating layers for a high-temperature part and for a low temperature part are formed by thermal insulating materials that are respectively in different thermal conductivities. CONSTITUTION:As fluid has such a characteristic that the temperature thereof is higher in its upper part while being lower in its lower part, a thermal insulating container 6 for high-temperature use is constructed so that a thermal insulating layer 7 for a top part 9 and for parts in its vicinities is made up of the thermal insulating material in high thermal conductivity, while the thermal insulating layer 7 for a bottom part 10 and for parts in its vicinities is made up of the thermal insulating material in low thermal conductivity, and thereby the thermal conductivity becomes gradually lower from the top part 9 down to the bottom part 10. The thermal insulating layer for a lid 11 to be inserted into an opening 8a of the container body 8 is made to be thick. Thereby, heat is dissipated to some extent through the top part 9 and its vicinities, making the temperature in the upper part of the container 6 lower to some extent, and the temperature in the container 6 can be equalized. Since the thermal insulating layer in the lid 11 is formed thickly, dissipation of heat through the lid 11 can be prevented.

Filed: 1989-12-01
Abstract: PURPOSE:To improve the peeling preventive effect of a plating resist film and the uncontamination effect of a plating solution by using a 2-thiobenzothiazole derivative having a specific substitutional group in a molecule as a main component. CONSTITUTION:A compound having a 2-thiobenzothiazole group and an unsaturated group and/or an epoxy group in a molecule is employed as a main component. The introduced 2-thiobenzothiazole group has a function inhibiting the precipitation of plating in the compound, and suppresses the intrusion of a plating solution to the boundary surface of the metal of a base material and a plating resist film. A functional group such as the unsaturated group and/or the epoxy group, etc., improves compatibility with a plating resist agent. These functional groups react with the resin group of a plating resist agent component, and a tough plating resist film is formed, thus inhibiting migration into the plating solution of a plating resist peeling preventive agent. Accordingly, the peeling preventive effect of the plating resist film and an effect excellent in plating solution uncontamination, etc., are acquired.
