Title: Magneto-resistance effect type magnetic head
Inventor: SUYAMA HIDEO
IPC: G11B5/39
Filed: 1983-12-23
Abstract: PURPOSE:To provide an increase in the level of a reproduced output, a decrease in variance and an increase in S/N by depositing and forming a nonmagnetic insulating layer consisting of SiO2, etc. over the surface of a magnetic base plate and the exposed surface of a nonmagnetic packing member having an insulating characteristic and depositing and forming a thin magneto-resistance effect film via said layer over the surface of the packing material and magnetic base body. CONSTITUTION:A nonmagnetic insulating layer 13 cosisting of SiO2, etc. is deposited and formed over the surface of a magnetic base body 1 and the exposed surface of a nonmagnetic packing member 2 having an insulating characteristic. A thin magneto-resistance effect film 4 is deposited and formed via said layer 13 only on the surface of the member 2. If the space of, for example, a gap (g) is made 0.25mum, the thicknesses of the insulating layers 13, 5 are selected respectively at 0.1mum, 0.15mum. Then, the step in the order of 100Angstrom  between the member 2 and the magnetic base body 1 is substantially absorbed by the layer 13. Since the head is thus kept free from the influence of the step between the circumferential edge 2 of the packing member and the body 1, the level of the reproduced output increases and the variance in the output level is decreased. The S/N of the reproduced output is substantially large.

Filed: 1988-09-30
Abstract: PURPOSE:To keep a mutual conductance in a saturated region of a GaAs MESFET within a prescribed permissible range and to enhance radiation resistance by specifying a carrier concentration in an active layer before irradiation with radiant rays. CONSTITUTION:A reduced amount of a carrier concentration NID', N2D in an active layer by irradiation with radiant rays of a total radiation dose of R is designated as DELTAND; carrier mobilities in the active layer before and after irradiation with the radiant rays are designated as mu and muA, respectively. In this case, a carrier concentration N2D in a lower-side layer 22 of the active layer before irradiation with the radiant rays is set at N2D>DELTAND/{1-betaL(mu/muA)}. As a result, even when the total radiation dose of R of the irradiated radiant rays is not only 1X10<9> roentgens or below but also above this value, a mutual conductance gm in a saturated region of a GaAs MESFET can be kept within a prescribed range (a permissible range decided by a signal processing circuit) at a preset radiation dose. Accordingly, a semiconductor device constituted so as to be provided with the GaAs MESFET and with the signal processing circuit functioning together with the FET can be operated normally according to an initial design value. Thereby, it is possible to enhance radiation resistance.

Abstract: PURPOSE: To obtain superior follow-up abilities of amplitude and phase in a wide band by constituting a 4-port microwave device, functioning as a magic-T network and adopting the combination of transmission mediums of a strip line and air strip lines on the both sides. CONSTITUTION: In a balanced-to-unbalanced transformer network, two output ports of connectors 135 and 140 have potentials which have the same amplitude and have phases shifted from each other by 180 deg.. Consequently, RF power inputted to the strip line port of a connector 130 has the same amplitude. However, it has a phase shift from those of the outputs of air strip lines of connectors 135 and 140. That is, the layout of an air strip line circuit is symmetrical, and connections of the strip line balanced-to-unbalanced transformer network are electrically symmetrical with respect to two outputs of connectors 135 and 140. Consequently, the follow-up abilities of amplitude and phase between two outputs of connectors 135 and 140 are superior.

Title: Head movement load reduction mechanism in rail-type universal parallel rule and the like
Inventor: MUTO HIROSHI
IPC: B43L13/04
Filed: 1990-09-19
Abstract: PURPOSE:To move a head smoothly by a small force by a method wherein a load of a tail roller to the surface of a drawing board caused by the weight of a lengthwise rail or the like is reduced by a magnetic force acting between magnetic bodies. CONSTITUTION:A handle 10a of a head 10 is grasped by hand, and a force is applied thereto in parallel to the surface of a drawing board 1 in the longitudinal direction thereof. As a result, a crosswise cursor 4 moves along a crosswise rail 2, and a tail roller 8 rotatably runs in the longitudinal direction on the surface of the drawing board 1 as a lengthwise rail 5 moves. When the lengthwise rail 5 moves on the surface of the drawing board 1, the lengthwise rail 5 is pressed in a direction (b) by a restitution magnetic force acting between magnetic bodies 13 and 14 so as to be vertically lifted upward from the surface of the drawing board 1. This magnetic force remarkably reduces a load of the tail roller 8 to the surface of the drawing board 1. In this manner, the lengthwise rail 5 smoothly moves on the drawing board 1. An operator can move the head 10 along the surface of the drawing board 1 by a small force.
