Abstract: PURPOSE:To improve strength of a SiC-C sheet by adding a dispersant, org. binder and plasticizer to polycarbosilane, finely pulverizing, adding specified synthetic resin thereinto to make a slurry, molding into a sheet, drying to obtain a green sheet and then baking. CONSTITUTION:200-500 pts.wt. of a dispersant such as a mixture solution of xylene and ethanol, 40-50 pts.wt. of an org. binder such as polyvinyl butylal, 30-40 pts.wt. of plasticizer such as dibutyl phthalate are added into 100 pts.wt. of polycarbosilane which does not melt because of its three-dimensional crosslinking structure. This mixture is finely pulverized, into which 50-100 pts.wt. of furan resin or phenol resin with about 5wt.% hardening agent is added to a slurry. This slurry is processed for removing bubbles and controlling the viscosity, molded into a sheet a doctor blade by method, etc., and dried at room temp. to 100 deg.C to obtain a green sheet. Then the sheet is fixed to a graphite setter and baked at 1200-1400 deg.C for 1-2 hours in N2 gas atmosphere to obtain a SiC.C composite sheet having 1.7-2.0g/cm<2> density and 3-6C/Si atomic ratio.

Filed: 1988-07-26
Abstract: PURPOSE:To check the abrupt volume increase of a lower chamber and to prevent the generation of cavitation by providing a cylindrical member for relaxing the abrupt pressure reduction of a piston lower chamber by descending with a piston at its descent time, starting to ascend by delaying a little more than the piston at its ascent time. CONSTITUTION:A cylindrical member 21 provided at the piston 4 external side eliminates the abrupt volume change of the piston lower chamber 7 by moving downward with inertia even in case of the ascent of the piston 4 by the repulsion force with the rapidly descending piston 4 striking a tool 2. Consequently, the abrupt pressure reduction by the repulsion of the piston 4 is eased, the bubble of the press oil inside of this lower chamber 7 inside is not developed and no cavitation is caused.

Filed: 1987-07-27
Abstract: PURPOSE:To prevent phosphorus mist from scattering and propagating out of a boat loader by a method wherein an exhaust system is installed to suck and exhaust the phosphorus mist scattering from a boat and wafer furthermore when the boat, after heat treatment, is drawn out of the loader, clean air feeding function is stopped to initiate the exhaust fuction. CONSTITUTION:When a heat treated wafer is drawn out into a boat loader, hot air and phosphorus mist are lifted above the wafer as a rising stream. This air stream is exhausted out of a clean room through an exhaust punching sheet 16 provided on overall ceiling part in the boat shifting channel by an exhaust system 20 installed in the channel. Furthermore, at this time, the feeding of clean air from the punching sheet 16 is stopped and the exhaust system 20 is to be started by opening a damper 21 of the system 20.
