IPC: H01F6/06
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To eliminate displacement movement following thermal contraction difference between constituting materials, for preventing occurrence of quenching by relating to a spacer bracket assigned between a superconducting coil and an inner bath, forming it with a material larger than the superconducting coil in thermal contraction amount. SOLUTION: For a superconducting coil 1,2-piece spacer brackets 4a and 4b are pressurized and assigned through an insulating material 3, with both facing surfaces integrated by welding, thus the superconducing coil 1 fixed. Then, in order that the compression-elasticity-distortion which is larger than the thermal-contraction-distortion difference between a spacer bracket and an inner bath be kept, with 2-piece inner baths 2a and 2b pressurized, their facing surfaces are welded and jointed. The spacer bracket is made of high- tensile aluminum, with the order of thermal contraction amount for component materials being spacer bracket>supperconducting coil 1 > inner bath (stainless steel). Thus, even when assembled under pressurizing force 0 at normal temperature, rigid fixing is provided between the superconducting coil 1 and the spacer bracket at LHe temperature of operation temperature.

Title: Method of detecting failure in fastening of screw
Inventor: YAMAGUCHI HIROAKI
IPC: B25B23/14
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent an accident by judging the loosening of a bolt caused by the crackings or the like of the bolt or a work in the case where a torque value is lowered to a predetermined detection level or lower. SOLUTION: Whether a held torque value (Tof) is more than a predetermined torque value (Tz) or not is judged, and it is judged that the fastening is normally executed when the value is more, and a normal state judgement output is sent. When the value is less as the result of the judgement, it is judged that the fracture caused by the generation of cracking or the like on a bolt 2 and a work 5, or the loosening immediately after the fastening, is generated, and the abnormal state judgement output is sent. When the bolt is fastened to a form and keeps its axial force, the reaction force by the residual fastening force is detected by a torque sensor 15 while rotating the bolt, and a low value close to a target value is indicated, so that whether the state is normal or not is judged on the basis of the value.  In a case of the cracking on the bolt 2 and the work 5, the bolt 5 is only rotated by the reaction torque, and the torque sensor 15 does not detect its reaction force, so that the generation of cracking is judged.

Abstract: PURPOSE:To enhance the operating uniformity of a unit semiconductor device included in a large-diameter semiconductor substrate and to increase a maximum interruption current by a method wherein various characteristics of the unit semiconductor device arranged inside the semiconductor substrate are checked while the unit semiconductor device whose distribution inside the substrate deviates from the average value is removed so as to make the device inoperative. CONSTITUTION:A number of slender strip-like unit semiconductor devices (GTO segment) 2 are arranged on a semiconductor substrate 1 in such a way that they are arranged in a radial manner on concentric rings. This segment 2 has four layers pE, nB, pB, nE whose conductivity type differs alternately at adjacent layers; each nE layer is strip-shaped and has a cathode electrode 3; gate electrodes 4 are formed on the pE layer in such a way that these gate electrodes surround the cathode electrode 3. A residual current of the unit GTO segment which has been broken faster is shared by more than one unit GTO segment which is interrupted slower so that the local concentration of the electric current can be limited. The unit GTO segment whose turn-off time is trimmed inside the semiconductor substrate 1 and is made inoperative. As a result, the share of the residual current at the time when the electric current is interrupted is alleviated, the breakdown-withstanding capacity can be increased sharply.

IPC: F02D17/02
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of after-fire by a method wherein an overheat state is detected and during operation at the number of deceleration revolutions lower than that during the occurrence of an overheat, an exhaust gas temperature is reduced by a temperature reducing means. SOLUTION: When the number of revolutions of an engine exceeds the given number of revolutions and an overheat is detected, an ignition control circuit 12 stops drive of a thyristor 17 and through the occurrence of a misfire by alternately stopping ignition of cylinders, the number of revolutions of an engine is reduced to the number of deceleration revolutions. In this case, an ignition advance amount of a working cylinder is controlled to an advance amount higher than an ignition advance amount corresponding to the decelerating number of revolutions. Further, an exhaust valve is controlled so that an exhaust stating timing is delayed from an ordinary exhaust starting timing corresponding to the decelerating number of revolutions.  This constitution discharges exhaust gas being sufficiently burnt having temperature being reduced, and prevents the occurrence of after-fire wherein green gas generated due to a misfire is burnt at an exhaust system.

Title: Method for manufacturing dry wood
Inventor: KIKATA YOJI
IPC: B27K5/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining an almost crack-free and warping- free dry wood. SOLUTION: The texture of a wood surface is softened by a heating method such as steam boiling. After that, the wood is disposed outdoors to be dried. In this case, air is blown to the wood horizontally and dried in the early stage of a drying process for the wood whose internal temperature is high. The interior of the wood softened by the heating process allows easy circulation of moisture, and the internal moisture of the wood rapidly migrates to the surface of the wood by creating a temperature gradient between the interior and the surface of the wood. Consequently, the reduction rates of the moisture content of the interior and the surface of the wood are almost equal and therefore, the shrinkage of the wood occurs simultaneously in the interior and the surface. Thus it is possible to prevent the cracking of the wood from occurring, coupled with the softening of wood cells.
