Title: Method for coating rare-earth element magnet
Inventor: YANO JUNICHI
IPC: C25D13/20
Filed: 1988-03-29
Abstract: PURPOSE:To enhance corrosion resistance markedly by adapting an alkaline aqueous solution containing Si or Al to the surface of an R-Fe-B magnet to apply electrodeposition painting thereto. CONSTITUTION:An epoxy resin is kneaded with a powdery R-Fe-B magnet and the kneaded mixture is molded into a ring shape. This molded body is immersed in an alkaline aqueous solution containing Si or Al and subsequently drawn up to be applied to a centrifugal separator and the number of rotations are changed to control the residual amount of the solution to form the first inorg. film having a thickness of 1-4mum. After this film is dried in an air bath having proper temp., the electrodeposition painting of epoxy resin paint is performed to form a secondary film. Therefore, the surface of the magnet is protected by at least one of the primary and secondary films to eliminate a directly exposed part and the environmental resistance of the magnet is markedly enhanced.

IPC: G11B5/10
Filed: 1981-05-20
Abstract: PURPOSE:To obtain the stable magnetic recording performance by having a desired bend form for a gimbal part which is put into the back groove part of a core slider and accordingly preventing a defect which is caused in the assembling process. CONSTITUTION:A gimbal pawl 27 is bent at a position near its root with an angle theta (theta: about 30 deg.). This pawl 27 is put into a back groove part 26 of a core slider and calked by a tool. Thus the pawl 27 is formed symmetrical by to each other centering on the part 26. Accordingly a gimbal 18 is set in parallel to the lower face of a core slider 14, and as a result the desired magnetic recording performance is obtained for a magnetic head 9. Furthermore the force acting on the direction where the tip of the pawl 27 opens left and right the side face of the part 26 is reduced compared with the conventional force. Thus the deterioration of the magnetic recording performance owing to the deformation of the slider 14 can be avoided for the magnetic head 6. At the same time, the breakage of the slider 14 is also prevented.

Title: Phase difference discriminating circuit
Inventor: OTA KAZUO
IPC: H03L7/08
Filed: 1988-03-31
Abstract: PURPOSE:To shorten a time for detection, to reduce an error in discrimination and to make a device small in size, by a construction wherein a high-speed pulse signal is counted in a prescribed number, so as to set a reset-set FF, only when a pulse signal corresponding to a phase difference between two signals is ON. CONSTITUTION:When signals S1 and S2 are inputted to input terminals 11a and 11b, a pulse signal S5 corresponding to a phase difference between them is outputted from an exclusive-OR circuit 2. A counter 21 counts a signal S8 from a high-speed pulse signal generator 22 only when the signal S5 inputted thereto is ON, and turns an output signal S9 ON when it counts up the signal S8 for a phase difference to be used as a reference. Then a reset-set FF 25 is set and an output signal S11 is turned ON. Therefore it is seen that the phase difference occurs between the signals S1 and S2. Besides, a counter 24 is reset when the signal S9 is turned ON, and turns an output signal S10 ON when it counts up the signal S8 in a prescribed number. Since the FF 25 is reset then, the signal S11 is turned OFF unless the signal S9 turns ON within a prescribed time, and a return is made to the initial state.
