Title: Cationic polymer dye
Inventor: TANIGUCHI KOICHI
IPC: C09B23/00
Filed: 1987-11-24
Abstract: PURPOSE:To obtain the title dye markedly increased in dyeing property, being capable of dyeing in a high concentration and causing no waste water pollution because the dye used can be perfectly exhausted by a dyeing piece, by bonding the terminal amino groups of the same or different monomer components together with a crosslinking agent. CONSTITUTION:The title dye is prepared by bonding the terminal amino groups of the same or different monomer components of formula I [wherein A is a (substituted) benzene ring, and B is a quaternized methylene active compound residue (e.g., a heterocyclic compound residue of formula II or III)] with a crosslinking agent [e.g., phosgene or a halogenated triazine (derivative)]. For example, a compound of formula IV, obtained from p-aminobenzaldehyde and 1,4-dimethylpyridinium methylsulfate, is reacted with cyanuric chloride, and the product is reacted with diethanolamine to produce a yellow dye of formula V. The dye obtained by this process has a markedly increased dyeing property, so that high-concentration dyeing is possible, and the dye used can be exhausted by a dyeing piece so that there is no fear of waste water pollution.

Title: Vacuum valve
Inventor: YOSHIGAE KIYOHISA
IPC: H01H33/66
Filed: 1989-11-13
Abstract: PURPOSE:To eliminate the need for enlarging the size of a vacuum valve and insulation plate or insulation tube without changing the construction material of the vacuum valve even under environment where temperature severely changes by providing a cylindrical part, extending in an axis direction from the periphery of a joining surface with an insulation body, on the joining end side on the fixed contact conductor side and the metal cylinder end part side of the joining surface of a coupling member with the insulation body. CONSTITUTION:Joining surfaces, ground and processed on the same plane with a ring groove 10 positioned therebetween, are formed on the lower surface of an insulation plate 21, and a cylindrical part having a length l1 is formed for forming a L- shaped cross section by being extended in the axial direction after being connected to the periphery of joining surface of a coupling member 2, together with the above joining surface. As a result, forces mutually acting between joining surfaces in one coupling member 2 are absorbed by a side in the axis direction of the letter L so as to reduce transmitted force. This can eliminate the need for enlarging the size of the insulation plate 21 of a vacuum valve. A high strength joining material is not needed in particular since strong force is not applied on the joining surface, the vacuum valve having a small size as the whole, inexpensiveness, and high reliability can be obtained.
