Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of a crack by stress of a folding-back part, and prevent disconnection of a foil conductor by making a thickness of a part folded back in a desired length of the foil conductor larger than a thickness of the other foil conductor part. SOLUTION: A heater element continues in a U shape, and is formed of a belt-like foil conductor unfolded in a plane shape by being folded back by 180 deg. in a desired length. A width of foil of a 180 deg. folded-back part 3 of this foil conductor is made larger than a width of the other foil conductor part. For example, it is made larger by about 10 to 20%. A sharp rise of the heat at the 180 deg. folded-back foil conductor part 3 can be restrained by this sheet-like heating heater element, and the occurrence of a crack by stress can also be reduced. Disconnection of the foil conductor can be prevented by the extent that the 180 deg. folded-back part becomes thick.

Title: Superconducting electromagnet device
Inventor: CHIYON CHIN KUN
IPC: H01F6/00
Filed: 1991-05-17
Abstract: PURPOSE:To enhance the performance of a superconducting electron magnet by arranging the following: an electromagnet support material which can be taken away from the superconducting electromagnet; and a plurality of cylindrical superconductors at the lower part of the superconducting electromagnet inside a cooling tank. CONSTITUTION:A superconducting electromagnet 5 is supported by a support material in cooling devices 1 to 3 before it is excited. After it has been excited, the support material is taken away and the electromagnet is levitated in a noncontact state. In order to levitate the superconducting electromagnet 5 in a noncontact support, a plurality of superconducting cylindrical bodies 4 are arranged side by side on the bottom part of the cooling devices 1 to 3. A magnetic field generated by the excited superconducting electromagnet causes a negative effect with reference to a group of the superconducting cylindrical bodies 4. As a result, the superconducting electromagnet 5 is levitated. At this time, one part of a magnetic flux generated by the superconducting electromagnet 5 is passed through the superconducting cylindrical bodies 4, and the electromagnet is levitated stably. When an oxide-based high- temperature superconducting material is used for the superconducting cylindrical bodies 4, a cooling operation can be performed easily. Thereby, the performance of the electromagnet 5 is enhanced.

Title: Copying machine
Inventor: OIKAWA TOMOHIRO
IPC: B65H15/00
Filed: 1984-07-10
Abstract: PURPOSE:To greatly shorten the transferring distance of papers to lower the possibility of damage of papers and to aim at shortening the time required for copying, by returning a paper just after an original image is transferred onto the paper. CONSTITUTION:Papers P fed out from a paper cassette 29 are merged from passages 31a into a passage 31b through which the papers P are introduced into an image transferring section 26B where a toner image on a photosensitive roller 28 is transferred onto the papers. The papers are then fed by a conveyor belt 32 into a fixing section 34 where the image is fixed. A reversing section 35 downstream of the fixing section 34 introduces the papers from their leading ends and feeds out them from their trailing ends to reverse the papers, and then the papers are temporarily stored in an intermediate tray 39 from which the papers are again fed by means of a roller 43 into the image transferring section 26B through a passage 43. Thus, an image is transferred to the rear surface of the papers P. Accordingly, when a plurality of images are transferred onto one paper for book binding, the conveying distance of the paper is greatly shortened so that the time required for copying may be greatly shortened, thereby it is possible to reduce damage of papers with a lower possibility.

Abstract: PURPOSE: To allow a radio equipment to receive a radio signal without noise by detecting the current change or the voltage change of a feeder such as a power line and applying an inverted phase output depending on a detection signal to a radio equipment so as to cancel the electromagnetic wave with the inverted phase signal. CONSTITUTION: An electromagnetic wave with a high frequency is included in a current flowing to a power line 5 when an electronic device 3 is in operation, When the electromagnetic wave enters an antenna of a radio receiver or the like, noise is caused. For example, a coil wound on the power line 5 is adopted for a current sensing element 6, a voltage differentiating a current waveform with time is generated in the coil. When a waveform eliminating a low frequency component by using the filter 7 is given to an input terminal 9a of a subtractor 9, the wave is superimposed on the antenna input signal to eliminate the noise. Then only a regular radio signal is outputted to an output terminal 9c of the subtractor 9.
