Title: Magnetic head
Inventor: MATSUNAGA HIROSHI
IPC: G11B5/187
Filed: 1985-10-07
Abstract: PURPOSE:To decrease the track pitch on a recording medium and to improve the recording surface density by coating both the side faces of a core with a nonmagnetic metallic film having the relative resistance of a low level. CONSTITUTION:The copper films 28 and 29 formed by plating, etc., are coated up to the boundary between the sloping surfaces 30 and 32 and a head face 32. When a high-frequency magnetic field produced from the gap between both surfaces 30 and 31 acts on the films 28 and 29, the eddy currents flow to both films 28 and 29 to produce the adverse magnetic flux. This magnetic flux functions to mask a magnetic field. Thus the high-frequency magnetic field leaked out from the gap between the surfaces 30 and 31 is reduced down to about 1/10 compared with a case where no copper film is coated. As a result, the width W3 of a track 42 is reduced double compared with the size equal to a reduced amount of the extra recording track width epsilon1. Therefore the pitch p1 of the track 42 formed on a magnetic disk 33 is reduced double compared with the size equal to the amount of reduction of the width epsilon1. This improves the recording surface density.

IPC: C08G69/26
Filed: 1982-12-22
Abstract: PURPOSE:To produce a water-soluble resin of excellent hydrolysis resistance, by neutralizing the carboxylic groups of a specified polyamic acid with a base. CONSTITUTION:A polyamic acid of a reduced viscosity >= about 0.05dl/g is prepared by reacting 2,3,5-tricarboxy-cyclopentylacetic acid (anhydride) with a diamine (e.g., p-phenylenediamine, p-xylylenediamine, or ethylenediamine) in a solvent which can dissolve the formed polymer, e.g., dimethylformamide. A water-soluble resin is produced by adding ammonia and/or an organic basic compound to the produced polyamic acid solution to neutralize the contained carboxylic groups to such an extent that the polyamic acid is rendered water- soluble. This water-soluble resin can give a polyimide of excellent heat resistance when it is imidated by heating.

IPC: F24F13/22
Filed: 1984-10-26
Abstract: PURPOSE:To prevent the fan locking accident due to the freezing of residual condensate during the winter from occurring by a method wherein the lowering of cooling capacity at overload is checked by controlling the level of condensate left in a base in response to the temperature condition on outdoor side. CONSTITUTION:A diaphragm 10 with a through hole 11 is fixed on a drain port 9, which is provided on the bottom surface of a base 8 for condensate. Gas or volatile liquid with large expansion coefficient with respect to the change of ambient temperature is sealed in the interior of the diaphragm 10.

The height of the diaphragm is expanded and contracted in response to the pressure in its interior. The height A of the diaphragm 10 is set to be lower than the gap B between the base 8 and a propeller fan 4 in order to drain the condensate from the drain port 9 outside an air conditioner, when the outside temperature is so low as to have the fear to cause to freeze the condensate left in the base 8.
