Inventor: HAYASHI YASUYUKI
IPC: B21B37/78
Filed: 1982-12-22
Abstract: PURPOSE:To obtain a sufficient effect for eliminating an increase of wall thickness by performing a speed reduction control of the roll peripheral speed of a stand located at the upstream when a prescribed part of the front or rear end of a blank pipe is rolled by prescribed stands located at the upstream and the downstream. CONSTITUTION:In a rolling method of a blank pipe by draw rolling the pipe through a group of rolling rolls consisting of plural stands, the roll peripheral speed of a stand located at the upstream is controlled by speed reduction when a prescribed part of the front or rear end of the pipe is rolled by the prescribed stands located respectively at the upstream and the downstream. Therefore, the responsiveness of a roll driving motor is enhanced to increase rapidly and surely a tension between the stands acting on the front and rear ends of the pipe, thereby a sufficient effect for eliminating the increase of wall thickness is obtained.

Title: Magneto-resistance effect type magnetic head and its manufacture
Inventor: SOEYA SUSUMU
IPC: G11B5/012
Filed: 1991-09-04
Abstract: PURPOSE:To suppress the occurrence of Barkhausen noise by providing a second magnetic domain controlling layer for magnetically applying a vertical bias across a magneto-resistance effect film. CONSTITUTION:A first magnetic domain controlling layer 30 for magnetically impressing a vertical bias across both end sections of a magneto-resistance effect film 40 is provided and a second magnetic domain controlling layer 45 for applying another vertical bias which is magnetically weaker than the above-mentioned bias across the central part of the film 40 is provided on or below the film 40. Accordingly, even when some pinholes or unevenness exists in the film 40 or a step is produced in the layer 30, the occurrence of Barkhausen noise can be suppressed, because the weakly coupled film 45 formed adjacent to the central part of the film 40 prevents the generation of magnetic poles. In addition, since the vertical bias applied by the layer 45 is weaker than that applied by the layer 30, an increase in anisotropic magnetic field is suppressed to a negligible level and the reproduction sensitivity of a magneto- resistance effect element is not affected by the increase even a magnetism sensitive section constituting the central part of the film 40 directly comes into contact with the layer 45.

Title: Automatic frequency control circuit
Inventor: MINEMATSU TORU
IPC: H03J7/02
Filed: 1991-09-04
Abstract: PURPOSE:To keep the frequency of an intermediate frequency signal with high accuracy. CONSTITUTION:A 1st intermediate frequency signal from a converter 2 is supplied to a mixer circuit 3, and it is multiplied with a local oscillation signal from a local oscillator 4. A 2nd intermediate frequency signal is supplied via an amplifier 7 to a demodulator 8, in which the signal is demodulated. The 2nd intermediate frequency signal from the amplifier 7 is supplied to a phase comparator 21, in which the signal is compared with a reference oscillation signal, from which a pulse Pd whose pulse width corresponds to a phase difference and whose polarity is in response to a phase lag/lead is obtained. The pulse Pd is supplied to a microcomputer 5 to measure the pulse width and the polarity for a prescribed period. When the pulse width is dicordant with a preceding pulse width (the frequency of the 2nd intermediate frequency signal and that of the reference oscillation signal are discordant), the local oscillating frequency is changed in a direction in response to the polarity of the pulse Pd to control the frequency of the 2nd intermediate frequency signal. Since the local oscillation frequency is controlled in response to the phase comparison output, the frequency accuracy of the 2nd intermediate frequency signal depends on the accuracy of the reference oscillation signal from a crystal oscillator 22 and is improved.
