Title: Signal reproducing device
Inventor: SHIMEKI TAIJI
IPC: G11B5/02
Filed: 1980-06-12
Abstract: PURPOSE:To get rid of a phase difference and to remove an even higher harmonic component, by connecting a delaying means for delaying an output of one of magnetic detecting elements, on the magnetic detecting elements haveing a differential constitution, for detecting a signal on a recording medium. CONSTITUTION:This device is equipped with an MR element 1 which responds to a magnetic field of the upper half of a recording track 3 on a magnetic tape, and an MR element 2 which responds to a magnetic field of the lower half, to which a current for a bias magnetic field and a current for converting a resistance variation to voltage are supplied from a constant-voltage circuit 6, respectively. Moreover, to one MR element 1 is connected a constant delaying circuit 7 having a prescribed extent of delay, and by differential-amplifying its output and an output of the MR element 2 by a differential-amplifying circuit 5, a reproducing output is obtained. Accordingly, even if the MR elements 1, 2 are installed to the recording track 3 in a state that the azimuth has been inclined, each output phase can be made to coincide to each other, and an even higher harmonic component is removed easily.

Title: Thermal expansion eliminating structure for insulative double structural body
Inventor: YAMAJI TADAO
IPC: F17C3/02
Filed: 1990-03-27
Abstract: PURPOSE:To remarkably reduce a thermal expansion rate of an inner wall in an insulative double structural body forming an insulative double pipe, by forming a pair of three-layer walls while bending the inner wall in the form of Z-character longitudinally oppositely, and composing an intermediate layer wall of a material with a large thermal expansion coefficient. CONSTITUTION:An insulative couple pipe having an insulative layer 14 between inner and outer pipes 12, 13 thereof is sealed by end plates 15 on its both ends. The wall of the inner pipe 12 is bent in the form of Z-character at two portions and in the directions opposite to each other axially. A pair of three-layer walls are thus symmetrically on the pipe wall. The three-layer wall 16 is composed of an inner layer wall 17 being a part of the inner pipe, an intermediate layer wall 18 and an outer layer wall 19. The intermediate layer wall 18 has a thermal expansion coefficient larger than those of other walls 17, 19. When fluid of high temperature flows in the pipe, the outer layer wall 19 of the inner pipe 12 expands in the direction of the end, the intermediate layer wall conversely in the direction of a longitudinal center X-X of the pipe, and the inner layer wall 17 in the direction of the pipe end. The expansion rate of the three-layer wall 16 is the difference between the total of the expansion rates of the inner and outer layer walls 17, 19 and the expansion rate of the intermediate layer wall 18. The thus obtained expansion rate is smaller than that in the case of the inner pipe along because the thermal expansion coefficient of the intermediate layer wall 18 is large.

Abstract: PURPOSE:To facilitate the control of the amount of grinding by a method wherein a grinding head is transferred in a direction normal to the outer circumference of a disk while it is pressed against the disk to grind and the velocity of the transfer of the disk in the radial direction is controlled selectively. CONSTITUTION:The grinding head 1 transfers from the inner circumferential section to the outer circumferential section as it processes the surface of the magnetic disk 3 with a grinding tape 2 under a predetermined pressure. In order to shape the magnetic disk 3 to a film 5 of a uniform angle of inclination and a uniform thickness, the position of a velocity change position detecting section 6 comprised of a plurality of detecting pieces is first detected. Then, simultaneously with the initiation of grinding, a velocity control signal is generated from a velocity setting output section 7 which corresponds to the detecting section 6 and the signal is applied on a velocity control section 9 via a velocity change rate setting section 8 so that grinding head drive section 10 is operated at a velocity corresponding to the velocity control signal. Thus, it is possible to determine freely the amount of grinding of the disk 3 in the radial direction and to control the amount of grinding in a simple manner.
