IPC: C08G69/00
Filed: 1984-03-12
Abstract: PURPOSE:To obtain an aliphatic-aromatic polyamide based polyamide resin having a high molecular weight and improved heat resistance and mechanical characteristic easily at a low cost, by adding a solvent to reaction raw materials, heating and reacting the raw materials which keeping the fluidity and distilling away the solvent, and carrying out the reaction under high vacuum to give a high polymerization degree. CONSTITUTION:A cystalline polyamide resin is prepared from raw materials in which either one of the diamine or dicarboxylic acid is an aromatic compound and the other is an aliphatic compound by the direct melt polymerization method. In the process, 5-50pts.wt. solvent is added to 100pts.wt. reaction raw materials, and the temperature is increased to react the reaction raw materials while keeping the fluidity and distilling away the solvent. The reaction is then carried out under high vacuum to give a high polymerization degree. The diamine component to be one of the raw materials is diaminodiphenylmethane alone or partially a mixture of m-xylylenediamine in the case of the aromatic compound or hexamethylenediamine in the case of the aliphatic compound. Adipic acid, etc. or terephthalic acid, etc. corresponding thereto may be used as the dicarboxylic acid component.

Filed: 1996-03-06
Abstract: PURPOSE: To prevent creeping discharge of an insulative spacer which supports an electrode in a vacuum. CONSTITUTION: An insulative spacer 3 for use in vacuum pinched by a cathode 1 and anode 2 has a projection or projections 4, wherein the center 6 across the thickness of that projection 4 which is located nearest the cathode lies nearer the cathode than the middle point 5 between the cathode and anode, and therein the relationship b/a>=0.4 holds, where (a) is the distance to the cathode from that surface of the projection lying nearest the cathode which is located on the cathode side, and (b) is the protruding length of the projection. According to this configuration, electrons emitted by a cathode side triple junction T charge negatively the ceramic side surface 3B of the insulative spacer on its cathode side, and thereby the electric field of the cathode side triple junction T is dropped so that electric discharge is prevented.  The projection 4 presents a greater discharge preventing effect when it is located nearer the cathode 1 and has a greater length.
