| 20090052954 | ELECTROPHOTOGRAPHIC ENDLESS BELT, ELECTROPHOTOGRAPHIC APPARATUS, AND ELECTROPHOTOGRAPHIC ENDLESS BELT MANUFACTURING METHOD - The object of the present invention is to provide an electrophotographic endless belt exhibiting high uniformity in transfer and high stability in running, and an electrophotographic apparatus having the electrophotographic endless belt. The present invention provides: an electrophotographic endless belt formed of a thermoplastic resin composition, characterized in that, assuming that the maximum heating shrinkage factor when a slice of the electrophotographic endless belt is hot-pressed in a temperature range higher than a melting point of the thermoplastic resin composition by 10° C. to 120° C. is L (%), 15≦L≦80 is established, and assuming that the maximum tensile rupture distortion attained by performing a heating tensile test using a slice hot-pressed at a temperature giving the maximum heating shrinkage factor in a temperature range of 80° C. to 200° C. is S, 0.10≦(S+1)/L≦0.17 is established; an electrophotographic apparatus having the electrophotographic endless belt; and a method of manufacturing the electrophotographic endless belt. | 02-26-2009 |

| 20090082210 | SUPERCONDUCTING-CABLE CORE AND SUPERCONDUCTING CABLE - The invention offers a superconducting-cable core that comprises a superconducting conductor and an insulating layer covering the outer circumference of the superconducting conductor. The superconducting-cable core is classified longitudinally into a cable portion and a jointing-structure-forming portion that is located at each end of the cable portion and that serves as the portion in which a complementary insulating structure is formed when jointed with another conducting member. Of the superconducting-cable core, the jointing-structure-forming portion is at least within the range from the end of the superconducting-cable core to the end of the complementary insulating structure. The jointing-structure-forming portion has an insulating layer whose insulation performance is higher than that of the insulating layer of the cable portion, so that even when the cable itself cannot be designed with a sufficient margin in its insulation, a highly reliable joint can be formed. | 03-26-2009 |

| 20090025979 | Coupling structure of superconducting cable - A coupling structure of a superconducting cable is formed at an end portion of the superconducting cable having a superconducting layer and an outer peripheral layer formed thereon. The superconducting layer is coupled to a coupling member. A holding member | 01-29-2009 |
| 20100021113 | Method of constructing a normal joint structure of a superconducting cable - Provided is a method of constructing a normal joint structure for connecting superconducting cables having a cable core and an optical fiber arranged along the cable core. With the method, which includes the steps of: pulling out an optical fiber from the end of each of two superconducting cables to be connected together and splicing the optical fibers thus pulled out; returning the excess length of the pulled-out optical fiber to a superconducting cable side upon the completion of splicing; and connecting the cable cores, it is possible to reduce the quantity of optical fiber housed in a joint box, and accordingly to downsize the joint box. | 01-28-2010 |
