IPC: C04B41/63
Filed: 1990-10-19
Abstract: PURPOSE:To obtain a fully chemically durable concrete tube having smooth inner surface at low cost by a method wherein spray coating with synthetic resin is applied on the inner surface straight part and on the inner surface of joint part under the condition that the concrete tube is horizontally installed and rotated at slow speed. CONSTITUTION:Under the condition that a concrete tube is horizontally installed on rotary stands and rotated at slow speed, primer is sprayed to a main body straight part 2 and the upstand part 3 and the socket part 4 such as B type joint part, C type joint part or the like. After the hardening of the primer, resin and filler are continuously sprayed to the inner surface of the concrete tube rotating at slow speed.

Title: Manufacture of polycarbonate sheet for optical disk base
Inventor: SHIMAOKA GORO
IPC: G11B7/26
Filed: 1985-12-16
Abstract: PURPOSE:To improve shock resistance and to prevent generation of cracks at the time of painting, by a method wherein a sheet molded by extruding PC resin whose molecular weight falls whithin a specific range is placed between mirror surface plates to which mirror finish whose surface roughness is less than 0.1mum has been applied and heat treatment is performed at a specific temperature and pressure. CONSTITUTION:Polycarbonate (PC) resin whose molecular weight falls within a range of 25,000-35,000 is extruded in a sheetlike state by a T die extrusion machine, cooled while a mirror surface is being transferred by a mirror surface roll whose surface roughness is less than 0.1mum and a PC sheet having a predetermined thickness is molded. The PC sheet is placed between mirror surface plates to which mirror finish whose surface roughness is less than 0.1mum has been applied and heat treatment is performed at the temperature of 160-180 deg.C and pressure of 0.1-30kg/cm<2>. When a heating temperature is less than 160 deg.C, a reduction effect of birefringence is low and when the same exceeds 180 deg.C, the mirror plate and PC sheet are stuck each other and thickness accuracy of the sheet becomes worse. Then when the pressure is less than 0.1kg/cm<2>, the sheet deforms by generating shrinkage during a process wherein orientation distortion at the time of extrusion is eliminated at the time of heat treatment and on the contrary, when the pressure exceeds 30kg/cm<2>, the thickness of the sheet varies.
