Title: Bearing abnormal vibration preventive device
Inventor: MOMOEDA KATSUROU
IPC: G01M13/04
Filed: 1983-05-30
Abstract: PURPOSE:To shorten the time of holding the speed for awaiting the rise of oil temp. at the time of starting by judging quantitatively if a journal bearing is stable, comparing the result with the critical speed for bearing stable operation, and thereby holding the bearing speed in stabilized range. CONSTITUTION:The bearing oiling temp. TL, revolutional speed omega, bearing oil- film temp. TF and bearing metal temp. TM are sensed to calculate the lubricant viscosity mu and bearing surface pressure P. On the other hand, the rotary shaft radius r, bearing radial clearance C, rotary shaft static deflection delta, rotary shaft critical speed omegac, viscosity mu and bearing surface pressure P are determined to calculate Sommarfeldt's number So, oil-film spring constant betaij, and oil-film damping factor gammaij. Therefrom the stability critical speed omegag is calculated, which is compared with the current revolving speed omega. If the revolving speed is higher than the stable speed, it is judged to be in unstable range, and the exhaust chamber degree-of-vacuum control 40 and oiling temp. control 41 are put in effect to return to the stable range. Thereby the time with oil temp. stand-by speed can be shortened.

Abstract: PURPOSE:To improve oxidation resistance, chemical resistance, thermal shock resistance, and strength by forming a pyrocarbon layer on the surface of a base material made of silicon carbide and then laminating a thin CVD film of silicon carbide on the above. CONSTITUTION:A pelletized matter prepared by the known method, e.g. by adding phenolic resin to a purified silicon carbide powder and kneading the resulting mixture is molded and the resulting molded body is heated to undergo the curing of resin, and calcination and purification are carried out, by which a porous base material of silicon carbide is prepared. A thin pyrocarbon film is formed on the surface of this base material by the known method, and then, a silicon carbide film is formed on this thin film by a CVD method. Since a part of the pyrocarbon layer is allowed to react with silicon in the base material of silicon carbide and formed into silicon carbide at the time of forming the silicon carbide film by the CVD method and also the surface of the pyrocarbon layer is allowed to react with the silicon forming silicon carbide by the CVD method and formed into silicon carbide, the bass material of silicon carbide and the silicon carbide film formed by the CVD method are allowed to adhere firmly to each other.

Filed: 1981-06-25
Abstract: PURPOSE:To eliminate the need for mounting and removing stages for a masking paper and improve workability by forming a level difference along the parting line of an undercoating paint film and a chipping resistant paint film on a substrate. CONSTITUTION:In a paint film forming body wherein a chipping resistant paint film 22 is formed on the desired part X of a substrate 10 formed with an undercoating paint film 20 over the entire surface, a level difference (h) rising roughly at a right angle to the side of the desired part X is formed along the parting line L between the film 20 and the film 22. Undercoating paint is applied over the entire surface of such substrate 10, and further a fluid film of chipping resistant paint is deposited on the part X. This eliminates the need for mounting and removing stages for masking paper and improves workability. Since the level difference (h) is roughly at a right angle to the surface X to be formed with the chipping resistant paint film, it is possible to make the parting line between the undercoating paint film and the chipping resistant paint film rectilinear and therefore the need for correcting and polishing stages is eliminated.
