Patent JP-H0319111-A (JP)
Title: Production of magnetic head
Inventor: HARA TAKANORI
IPC: G11B5/23
Filed: 1989-06-16
Abstract: PURPOSE:To permit a screw torque to easily have a margin and to easily control a pressure-fixed torque by providing flat areas where V-shaped grooves are not formed so that they correspond partially and between a pair of core blocks. CONSTITUTION:When a pair of core blocks B are jointed, respective flat areas 2c are confronted each other and soft magnetic metallic thin films 4 and the flat areas 2c receive pressure force at the time of joint. Namely, pressure force can be enlarged a little since a pressure-receiving area receiving pressure force is enlarged by providing the flat areas 2c, and the allowable width of pressure force is enlarged. Consequently, the screw torque can be set somewhat large when pressure is given on the bias. Thus, it is easy to give the margin for the screw torque and the control of the pressure-fixed torque is facilitated.

Abstract: PURPOSE:To perform retrieval in a short time by retaining the last read key and deciding on the moving direction of a pointer according to the larger/small relation between a desired key and the retained key and accessing a memory successively. CONSTITUTION:The contents of a key register 3 stored with a key to be retrieved are compared with the contents of a key holding part 4 to send an advance direction indication to an advancing part 6 which advances a pointer 5 for specifying a storage location to be read out in an increasing or decreasing direction.

Filed: 1986-07-01
Abstract: PURPOSE:To reduce the thickness of a semiconductor element by laminating a film-like photosensitive resin composition on a circuit substrate on which the element is placed, and then exposing it to reduce the thickness of the film constantly. CONSTITUTION:When a photosensitive resin layer is formed on a circuit substrate on which a semiconductor element is placed, the layer is formed by laminating a film-like photosensitive resin composition by means of heating.

Title: Head floating amount measuring device for hard disk
Inventor: OKAWA YOJIRO
IPC: G11B21/21
Filed: 1993-06-25
Abstract: PURPOSE:To highly accurately measure a floating amt. by deviating one of two beams of interference light splitted by a beam splitter from the other one in phase by -pi/2 with polarization plates and calculating the floating amt. by measuring a light quantity of this beam of interference light. CONSTITUTION:Interference light C of the two beams of reflected light A and B transmitted from a polarization beam splitter 5 is splitted into interference light D and interference light E by the beam splitter 10. One phase out of the phases of the two splitted beams of the interference light D and E is deviated from the other phase by -pi/2 with polarization plates 11 and 12. A light quantity I1 of the interference light D is measured by a photodetector 13 and, at the same time, a light quantity I2 of the interference light E having the different phase from that of the interference light D by -pi/2 is measured by a photodetector 14. The light quantities I1 and I2 are calculated by specific equations, and then a floating amt. (h) is calculated. Consequently, by giving the specified phase difference by the polarization plates 11 and 12, a change in light quantity due to a deviation of the interference light is canceled from the light quantities I1 and I2 of the two beams of the interference light D and E, so that the head floating amt. (h) can be calculated with high accuracy.

Title: Plane type optical control element
Inventor: FUJIWARA MASAHIKO
IPC: G02F1/015
Filed: 1986-07-02
Abstract: PURPOSE:To take a high erasion ratio at a low voltage, and to operate at a high speed by constituting the titled element of a semiconductor optical waveguide which contains a specific multiple quantum well structure and a layer on which a diffraction grating is formed, in a part of a waveguide layer and a clad layer, a means for applying an electric field, and a means for leading roughly vertically a light beam to each layer. CONSTITUTION:When a light beam 10a of lambda=1.32mum is made incident from on a mesa 7, at first, a diffraction grating 5 does not satisfy a Bragg condition, and the light beam passes through a substrate as it is and emitted as a light beam 10b. Subsequently, when a reverse bias is applied between electrodes 6, 8, an electric field is applied to a multiple quantum well (MQW) waveguide layer 3, an absorption coefficient increases against the light beam of lambda=1.32mum and the emitted light 10b starts an attenuation, and also. the Bragg condition is varied by a variation of a refractive index of the MQW, and in some electric field, the incident light 10a is couple to a waveguide light 10c, the emitted light 10c is decreased greatly, and a plane type optical gate element can be realized. In such a way, a large erasion ratio can be obtained without taking greatly an optical absorption length (MQW layer thickness), and as for an operation, speed, several GHz is obtained easily by reducing a CR time constant which is determined by an element capacity Q and a series resistance R.
