Title: Method of increase of electric current transportation capacitance of high-temperature superconducting body
Inventor: RAIA KURUUSHINNERUBAUMU
IPC: C01G1/00
Filed: 1995-03-28
Abstract: PURPOSE: To increase the current transportation capacity of a high TC superconductor substance, by irradiating high-temperature superconductive substance with light particles, and making the element within the superconductor substance bring fission into existence thereby forming a columnar defect dispersed greatly in each direction. CONSTITUTION: A high-temperature superconductor, which has one or more kinds of elements fissioning by light particles, is prepared. This high-temperature superconductor is irradiated with light particles which have enough energy for contained elements to cause fission. Hereby, a columnar damaged defect which extends, being dispersed in each direction on high level is made within the superconductor. By the formation of this defect, the magnetic vortex generated within the superconductor is pinned, and a superconductor bulk line material which has large current transformation capacity can be obtained.

Title: Hydraulic shock absorber
Inventor: WATANABE SEI
IPC: B60G17/015
Filed: 1992-02-20
Abstract: PURPOSE:To prevent the lowering of damping force caused by the rise of oil temperature by rotating a shutter in the opening direction at the normal temperature time to enlarge oil passage area, and rotating the shutter in the closing direction at the high temperature time to minimize the passage area. CONSTITUTION:At the expansion stroke time of a piston rod 11 and under normal temperature, a heat-deformed member 26 is in the contracted state, and a shutter 19 is in the valve opening position by the energizing force of a coil spring 25, so that the passage area of an expanding side oil passage 14 is fully opened to generate damping force. When a hydraulic shock absorber 8 is operated hard in off-road travel and oil temperature in a cylinder 9 rises, the heat-deformed member 26 is expanded to rotate the shutter 19 into a valve closing position against the energizing force of the coil spring 25 and thereby to throttle the passage area of the expanding side oil passage 14. The passage area of the expanding side oil passage is thus throttled even if oil viscosity is lowered by temperature rise so as not to generate the lowering of damping force. At the contraction stroke time, oil in a cylinder lower chamber 9b flows into a cylinder upper chamber 9a through a contraction side oil passage 15, and damping force is generated by contraction side damping force generating mechanism 30.

Abstract: PURPOSE:To enable coaxial conductors to be smoothly twisted, and the ends thereof to be flattened in a multiple way by adopting an elliptical form, instead of a rectangular form, for the PVC jacket of the coaxial conductors, and providing a recess at the central upper position of the jacket. CONSTITUTION:25 coaxial conductors (50 cores) having a PVC jacket 1 of approximately elliptical form are stranded, and covered with an intermediate sheath of PVC. In addition, a shield braid is used to cover the sheath. The conductors so formed are cut to the prescribed length. Then, the sheath at both ends is peeled and the coaxial conductors are taken out for arrangement and fused in a flattened way. As a result, only both ends of the conductors can be flattened in a multiple way, and the intermediate section thereof becomes round. Also, the coaxial conductors are so laid in parallel that two conductors can keep a constant pitch from each other, and integrated with the jacket 1, thereby enabling a connecting work to become easy. Also, a recess section is formed at the central upper position of the jacket 1 and a processing work for flattening the ends in a multiple way can thereby be made easy. According to this construction, the conductors can be smoothly stranded, and reliability or the like can be improved.
