Title: Method and device for cooling feed path for cryogenic electric device
Inventor: JIYANNKUROODO KERUMARETSUKU
IPC: H01R4/68
Filed: 1991-11-20
Abstract: PURPOSE: To provide a method and a device for cooling a feeder line between an ambient temperature terminal and an electric device which is dipped in a bath containing a cryogenic fluid, and for optimizing the feeder line for superconducting devices, for instance, a superconducting electric device for a powered railway car actuated with no load or a weak current, a rated current and a current larger than the rated current. CONSTITUTION: When a strong current flows in a feeder line, cooling air or fluid drops to a first level 14A of a passage 14, ascends a passage 9 along a rib and then is discharged or streams via a pipe 15, so as to be circulated again after heat exchanging with the atmosphere. When the feeder line carries a rated current, a passage 17 is connected to a suction pipe 16 carrying dry air (or another fluid) whose temperature is only slighths higher than the ambient temperature, so that it is used for cooling the feeder line.

IPC: B03C3/16
Filed: 1988-12-01
Abstract: PURPOSE: To recycle particles of colored materials in waste water without forming any waste water sludge by introducing waste water falling down from a collector electrode into a separator and there, separating colored material particles and solvents from the waste water based on the differences in density between the water and the particles and solvents.  
     CONSTITUTION: In this method, an electric field that has a 1,000 to 8,000V voltage and a 0.5 to 10kV/cm electric field strength, is formed between an ionization electrode and a collector electrode. A spray of waste water of 10 to 80°C is downwardly applied to the electric field in the vertical direction from above and the waste water falling down from the collector electrode is introduced into a separator. In the separator, particles of colored materials and solvents are separated from the waste water based on the differences in density between the water and the particles and solvents.

Title: Rotary magnetic head device and magnetic recording method
Inventor: ICHIKAWA HIROSHI
IPC: G11B5/024
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To minimize slender recording on the original recording track at the editing starting point by erasing information prior to recording new information with a flying erasing head protruding out of the track to be recorded with the new information in the upstream direction in its widthwise direction. SOLUTION: When erasing is started by the flying erasing head 1d, erasing by the next head 1c is also started in the same manner from its contact period. In this case, at the reproducing time by a recording and reproducing head 1a, an erasing timing signal is generated from a timing signal, and is inputted to an erasing changeover switch for the head 1c by a system controller 24. After erasing operation of the head 1d, the actual write of an editing signal is started from a period of contact of the tape with the head 1a after 1.5 times the cycle of a head switch signal. From the point of this time, a 2nd timing signal is editorially changed during reproduction of the head 1a in an ITI area 21, and a new information signal is given to the head 1a by the controller 24.
