Title: Finish machining method for cylindrical work with small wall thickness
Inventor: SENDA HARUMITSU
IPC: B23P25/00
Filed: 1992-05-25
Abstract: PURPOSE:To establish a finish processing method for yielding products with high precision by eliminating deformation after processing due to influence of residual stresses generated by the coarse machining process. CONSTITUTION:A sensor 11 measures the shape of a work after each application of processing, and the output therefrom is fed to a displacement meter and a recorder 13, and thereupon a strain amount calculating circuit 14 calculates the max. strain amount epsilon. A low-pass digital filter circuit 15 eliminates fine variation resulting from the measuring error, while a finish processing region judging circuit 19 compares the strain amount at this time with the foregoing amount of processing strain. FlagV=1 generates judging that the bottom V of the strain amount is passed, and the processing is repeated until FlagP=1 which should result in a judgment that the crest P of the strain amount is passed. The processing is repeated until a judgment is generated that the current amount of processing strain is below the reference value A, and when it is exceeded downward, the finish machining process takes place.

Title: Oxide superconductive wire material
Inventor: TAKEDA YUKIO
IPC: H01B12/06
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a wire material of a high Tc (critical temperature) by sticking and firing an oxide superconductive layer around a metallic thin wire having heat resistance and oxidation resistance. CONSTITUTION:Oxide superconductive powder and organic binder are mixed to make slurry. A heat-resistant, oxidation-resistant, thin metallic wire is passed through the slurry to make the slurry of oxide superconductor stick around the thin metallic wire. The wire material is then heated to decompose the organic binder contained in the slurry and is further fired in the ambient atmosphere or in an oxygen atmosphere up to a temperature at which the oxide superconductive powder is sintered to obtain a wire material with the superconductive layer formed around the metallic thin wire. This makes it possible to easily obtain the wire material having a high Tc and no electric resistance.

Title: Hydraulic control system
Inventor: KURISUTOFUA JIYON GURIINUTSUDO
IPC: F15B11/08
Filed: 1984-07-30
Abstract: in a continuously-variable-ratio transmission of the toroidal ace rolling traction type, each roller is mounted between the opposing disc surfaces in a roller mounting which is displaceable by an hydraulic ram. Each end of the ram has a piston (13 or 14) at the end of the roller mounting sliding in a cylinder (15 or 16).The hydraulic control system has a combined flow divider and pressure control valve (23) which responds to external forces (C1 or C2) from solenoids to shift the roller mounting.Fluid flow in both hydraulic circuits (P, JJ', L' L, R, T and S, MM', K'K, Q, T) is always equalized by the valve (23). Thus displacement of the spools (S1, S2) away from equilibrium, by restricting inlet and outlet ports (R and S or P and Q), raises the pressure in one ram chamber (16 or 15) and displaces the ram. Moreover, the same pressure tends to return the spools to the equilibrium position. Hydraulic stopping of the ram occurs when either ram chamber port (L' or K') is restricted by a piston approaching its extreme position.
