Title: Method and device for production of magnetic recording medium
Inventor: KATO MIKIHIKO
IPC: G11B5/845
Filed: 1985-01-09
Abstract: PURPOSE:To obtain a disk having high performance with low modulation by setting plural rod magnets alternately, obliquely and reversely with each other in the shift direction of a supporter together with the random orientation of magnetic powder when a magnetic layer is formed on a belt-shaped magnetic supporter by a coating process. CONSTITUTION:For production of a flexible magnetic disk, a sheet, etc., a belt-shaped supporter 12 of polyethylene phthalate, etc. is shifted toward an arrow head A from a feed roll 11 and taken up to a take-up roll 14. At the same time, a magnetic coating liquid 16 is applied to the supporter 12 through a coating head 15 for formation of a coating film 16'. Here the 1st and 2nd rod type orientation magnets 17 and 18 are set under the supporter 12 so that they are oblique, alternate and reverse to each other toward the direction A with the magnetic poles set different from each other at the side toward the supporter 12. In this case, the magnetic field intensity of both magnets produced in the direction A is set at <=50Oe respectively. Thus the magnetic particles are orientated at random assuredly. This can prevent the modulation with which the reproduction output of the coating direction is higher than other directions when a disk obtained by cutting the supporter 12 containing a magnetic layer is reproduced.

Abstract: PURPOSE:To enable to detect the leakage quickly by a method wherein an inside tube is provided with grooves to detect leakage and the leakage of water is detected by a water leakage detector while the leakage of refrigerant medium is detected by a pressure detector through the grooves, in the heat exchanger for supplying hot-water produced by a refrigerating cycle. CONSTITUTION:Gas of high-temperature, high-pressure refrigerant medium from a compressor 1 heats water for supplying hot-water in the heat exchanger 2 for supplying the hot-water. In this exchanger 2, the inside of the tube 10 equipped with the leakage detecting grooves is utilized for the path of the water for supplying hot-water while a space between an outer tube 10-4 on the leakage detecting grooves 10-5 and an outside tube 11 is utilized for the path of the refrigerant medium. When errosion is advanced into the inner tube 10-1 and the water leakage is caused, water flows from the leakage detecting grooves 10-5 into a cap 23 and operates the water leakage detector 27 by conducting an electrode 26. On the other hand, when a crack is generated in the outer tube  10-4, the gas of the refrigerant medium is flowed into the leakage detecting grooves 10-5 and the pressure in the cap 23 is increased, the gas operates the pressure detector 20. Then, the compressor 1 is stopped by these operations and, whereby, mixing of the refrigerant medium or oil for a refrigerating machine into the supplying hot-water may be prevented.

IPC: H01F41/00
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent noise of a coil device and simplify an assembling method of the coil device. SOLUTION: In this assembling method of a coil device, a preheated center leg 3 of one core A is inserted into a cavity 6 of a bobbin 5, and after applying a hot-melt 13 preheated up to the melting point to a contact face of the center leg 3 of the core A, a preheated center leg 3 of the other core B is inserted into the cavity 6 of the bobbin 5. After that, each outside leg of a pair of core A and B is fixed, the hot-melt 13 is cooled and hardened, thereby the center legs 3 of a pair of core A and B are tightly bonded and fixed, and the pair of core A and B fixed. This makes it possible to prevent buzz noise generally caused by the vibration generated from the air gap between the center legs 3 of the pair of core A and B.  Moreover, as the air gap at the contact face of each center leg 3 of a pair of core A and B is filled with an insulating resin, a mica paper and a bakelite plate are not needed, and resultingly the assembly of the core device becomes simplified. Therefore, this makes it possible to prevent buzz noise and simplify the assembling method of the coil device.
