Title: Recording and reproducing device
Inventor: KANO KIYOSHI
IPC: G11B5/53
Filed: 1990-08-27
Abstract: PURPOSE:To contrive compatibility of good recording and reproducing characteristics and life characteristics of a head and a tape by changing a tape tension value of a rotary cylinder part in accordance with a revolving speed of a rotary cylinder. CONSTITUTION:The device is provided with a revolving speed variable means 62 for varying the revolving speed of the rotary cylinder 5 at the time of recording or reproducing and a tension variable means 63 for varying the tension value by tension control means 14, 33, 45 and 46 in accordance with the revolving speed of the rotary cylinder. Then, a tape floating amt. is decreased by increasing the tape tension of the rotary cylinder 5. Then, when the revolving speed is large, the tension is increased, and when the circumferential speed is small, the tension is decreased, so that the tape floating amt. is uniformized or reduced in its variable amt. as against a variation of the revolving speed. By this method, good recording and reproducing characteristics and life characteristics of the head and the tape are compatible.

Title: Chemical decontaminating method and device therefor
Inventor: NAGASE MAKOTO
IPC: G21F9/28
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To make the water in the outlet of a resin tower satisfy a drainable quality condition and simultaneously attain the reduction in concentration of a decontaminating agent and the regulation of water level by decomposing a reductive decontaminating agent guided from a part to be intended and passing water to a mix bed resin tower. SOLUTION: In decontamination process, a reactor recirculating pump 3 is started, and the temperature is raised by use of a circulating pump 5 and a heater 6. When the temperature reaches a prescribed temperature (90±5 deg.C), oxalic acid as reductive decontaminating agent any hydrazine as pH regulating agent are injected from a chemical tank 26 to a reactor 1 by use of a chemical injection pump 27. When the oxalic acid concentration reaches a prescribed concentration (0.2%), the chemical injection pump 27 is stopped to end the injection of oxalic acid, and reductive decontamination is performed. The cracked gas generated in a reducing agent decomposing device 16 is separated in a surge tank 17 and returned to the reactor 1 through a degassing line 24.  Since most of oxalic acid of the decontaminating solution flowing from the tank 17 is decomposed, the decontaminating solution is cooled to 80 deg.C or lower by a cooler 18 and then guided to a mix bed ion exchange resin 19 to remove the undecomposed oxalic acid, metal ions and the like.
