Title: Manufacture of oxide super conductor
Inventor: NAKAYAMA SHIGEO
IPC: H01L39/24
Filed: 1988-06-06
Abstract: PURPOSE:To improve remarkably the density of critical electric current, while the crystal structure of super conductive oxide is rearranged in the direction to which electric current is apt to flow by sintering the super conductive oxide powder in magnetic field after its press forming. CONSTITUTION:In the manufacture of oxide super conductor, after surface conductive oxide powder has been formed into a prescribed shape, it is sintered by heating. Then, said forming is carried out by the press in magnetic field. The super conductive oxide powder has oxygen defect delta, and it has e.g. the perovskite type-structure of oxygen defect-type (LnBa2 Cu3O7-, delta is normally the number of one or less). In the press forming, before the super conductive oxide powder is compressed, and its each particle is restrained, said particle is compressed, while the magnetic field is applied perpendicularly to electric current path. The strength of the magnetic field in said time is preferably 1.0T or more. When the strength of this magnetic field is less than 1.0T, the reorientation of its crystal becomes unsufficient. By pressing in the magnetic field, the crystal structure in the super conductive oxide is rearranged in the direction to which electric current is apt to flow due to the effect of the magnetic field, whereby the density of electric current is heightened.

IPC: F16J15/328
Filed: 1986-06-16
Abstract: PURPOSE:To reduce the fluctuation of the sealing performance by vulcanizing the lip end section of a seal lip integrally while employing resilient rubber members of different quality at the hermetically sealed fluid side and the atmospheric side with a marginal section being remained at the atmospheric side thereafter cutting the atmosphere side marginal section and forming an atmospheric sideface. CONSTITUTION:A meal die 20 is fastened then respective resilient rubber members 30, 31 mounted on a lower mold 21 are heated and pressurized. Consequently, a marginal section 32 is formed at the atmospheric side of the lip end section 7 by the resilient rubber member 31. Then the marginal section 32 is cut by means of a cutter so as to form the atmospheric sideface at the lip end section 7. Consequently, the cut face of the sideface section 30a of the resilient rubber member 30 is exposed on the side of the atmospheric sideface of the lip end section 7, and the sliding face 9 at the lip end section 7 is in the area W. Since the resilient rubber member 30 is formed uniformly with a specific thickness, the width W1 of the first sliding face 91 at the hermetically sealed fluid side can be formed into a constant width at all times, and since the width W1 of the sliding face 91 is constant even after long term usage, the sealing performance can be maintained.

After the S/N of the transmission signal is thus improved, the voice signal 95 is outputted to a level adjustment circuit 11. The cut-off frequency of the high pass filter 10 has a characteristics of 1kHz. The level adjustment circuit 11 adjusts the level of the signal after elimination of the ambient noise component 102 by the high pass filter 10 to a constant level.

Filed: 1983-08-01
Abstract: PURPOSE:To realize a compact and economical apparatus, by opening and closing a discharge gate by detecting the current of a geared motor, which drives an earth and sand compressing screw, to stop and fix a filter cylinder. CONSTITUTION:When a geared motor A is driven, a precipitation shaft 26, a rotary plate 8, a rotary brush 3, a scraper 4 and a precipitation screw 5 are together rotated. When the compression of coarse sand advances and the ratio of coarse sand in an earth and sand compressing pipe 19 increases, the friction force of an earth and sand compression screw shaft 20 increases and shaft power increases to increase the current value of a geared motor B. When a compressive dehydration chamber 21 is filled with coarse sand, the current value of the geared motor B for driving the above mentioned screw shaft 20 is detected and a discharge gate driving geared motor 20C is started to open a discharge gate 22. When coarse sand is discharged, the current value of the geared motor B is lowered and, therefore, the discharge gate 22 is again closed. As a result, a compact and economical apparatus for removing coarse sand from muddy water can be realized.
