Title: Magnetoresistance effect type magnetic head and its manufacture
Inventor: YONEDA HIROSHI
IPC: G11B5/39
Filed: 1981-04-30
Abstract: PURPOSE:To completely suppress a demagnetizing field and to minimize the dead band of an MR element, by using a high electric resistance material for a demagnetizing field suppression magnetic substance film, directly connecting the MR element and the demagnetization suppressing film and minimizing an overlapped part of the two. CONSTITUTION:As a demagnetization field suppressing magnetic substance film (hereinafter suppressing film), NiZn ferrite is used, the upper ridge of an MR element 2 is direct contact with a lower end 8a of a suppressing film 8 with overlapping. The film 8 can be regarded as an insulation material. The thickness of the MR element is 0.05mum and the thickness of the film 8 is 0.15-1.0mum. Thus, the MR element is contact with the film 8, then the suppression of the demagnetizing field can completely be made. Since the width of overlapped part of both the films can be taken as <=1mum, the blind sector of the MR element can be minimized. The MR element is vapor-deposited on a base, a conductor films is vapor-deposited on it, and a pair of the element and film are formed left and right. Unnecessary parts of the MR element are removed by etching.

Title: Shaft sealing device
Inventor: OKAMOTO KOUICHI
IPC: F16J15/44
Filed: 1979-05-22
Abstract: PURPOSE: To provide a rotary shaft sealing device having stable performance and free from seal breakdown without increasing the seal length by varying the axial depth of the screw seal groove in the axial direction in the liquid seal of shaft.  
     CONSTITUTION: A screw groove 4c cut in the outer periphery of a supply and exhaust pipe 4 in the direction opposite to the direction of rotation has a reducing depth toward the low pressure side. The seal is effected by making the use of pumping effect provided between stationary surface 85 and screw groove 4c. The depth of the groove is set such that the radius of the groove bottom is equal to or greater than the radius of the gas-liquid boundary which is related to the water pressure on the stationary wall surface at the rated rpm. Thus, the gas-liquid boundary is not produced within the screw groove, and the seal breakdown can be prevented without need for increasing the seal length beyond the required length. Also, without the gas-liquid boundary formed in the screw groove and with the liquid always in contact with the groove bottom, the pumping effect can be improved, and the length required for the screw seal can be reduced.
