Title: Magnetoresistance effect magnetic head
Inventor: KANDA HIDEKAZU
IPC: G11B5/39
Filed: 1993-09-20
Abstract: PURPOSE:To simplify the constitution and prevent noises from a control circuit or the like, by providing a fixed resistance for regulating the amount of a sense current fed from a constant voltage circuit, or a fixed resistance and a capacitor for a reproducing circuit at a portion of a lead conductor of an MR element. CONSTITUTION:An MR element 11 and a fixed resistance film 12 are simultaneously formed on a substrate. A pair of forked lead conductors 13 are formed out of an Au film. A part indicated by a chain line in the drawing is an MR head 15. One end of the forked lead conductor from the MR element 11 having the fixed resistance 12 is connected to a constant voltage source, while the other is grounded. The lead conductor without a fixed resistance is, via a DC cut-off capacitor 14, connected to a reproducing circuit 16. When the MR head 15 moves on a recording medium, voltages at both ends of the MR element 11 are changed by a magnetic flux due to a magnetic recording, which are processed by the reproducing circuit 16 thereby to output a reproducing signal. In the constitution, the reproducing circuit for the MR head is simplified and, electromagnetic noises are not mingled from the outside through the reproducing circuit, so that a high-quality reproducing signal is obtained.

Title: Method and device for assembling and adjusting optical head
Inventor: MATSUI TSUTOMU
IPC: G11B7/08
Filed: 1988-09-17
Abstract: PURPOSE:To speed up the assembling adjusting process of an optical head by using a sensor jig having a light detector and executing the (z) axis adjustment and the xy axis adjustment of a lens block with one adjusting operation only respectively. CONSTITUTION:A sensor jig 14 having a light detector 121 to receive a return laser light by specifying a beam size at the position to extend the light path length more than the focusing position to the error signal of the return laser light guided to an return path optical system of an optical head and a light detector 15 for detecting a reproducing RF signal is used. After the sensor jig 14 is installed to an optobase 10 by the same axis as a return path light axis L, a reflecting body is irradiated by the laser light from a semiconductor laser 11A through an objective lens 13. While the return light to a return path optical system is received by the light detector 121 of the sensor jig 14, a lens block 14 is movably adjusted so that the difference between the sum of the detecting output of a light receiving element 121A of the center and the sum of the detecting output of a light receiving element 121B of the periphery can become zero or DELTA+ or -delta. Consequently, the adjustment of the xy direction of the light detector and the adjustment of the (z) direction of the lens block can be simply and easily carried out with one adjusting operation.

Title: Spindle motor mounting device for machine tool
Inventor: KOMATSUBARA HIDEO
IPC: B23Q5/04
Filed: 1986-10-02
Abstract: PURPOSE:To make adjustment to the center-to-center dimension of a pulley, by installing a motor adapter plate slidable in both tension and relaxation direction of a belt, and also both first and second elastic tractive devices acting to draw this adapter plate to these tension and relaxation directions. CONSTITUTION:When a spring energizing bolt 84 in a first elastic tractive device is loosened to some extent and a motor plate 22 is made to slidingly go down in leaving a Belleville spring 82 maintained intact without keeping it in a state of being energized, a second elastic tractive device receives each weight of the motor adapter plate 22 and a spindle motor 18, compressing a Belleville spring 68. At this time, a belt 30 comes to a standstill at that point that its slackness is eliminated. Next, when the spring energizing bolt 84 is retightened and the Belleville spring 82 is compressed, the motor adapter plate 22 is gradually drawn downward, and elongation in the tension direction is produced in the belt 30, so that is should be set so as to have transmission of proper driving force performed. With this constitution, even when secular elongation in the belt 30 has occurred, it is simply adjustable.

Title: Arc correcting mechanism for xenon lamp
Inventor: TANIMOTO AKIHITO
IPC: H01J61/02
Filed: 1990-09-05
Abstract: PURPOSE:To hold a magnet at a fixed position at all times and to stabilize arc discharging by arranging a roller rotatably in a hole bored in the rear peak part of a reflector and fitting the magnet for arc correction to the roller. CONSTITUTION:When a display device is tilted at a proper angle and light is projected on a screen, the xenon lamp 1 and a reflecting mirror 2 rotate corresponding to the angle. As the reflecting mirror 2 rotates, the roller 15 also rotates along the edge of the hole 14, but does not shift in position and is held at the same position. Further, a holding part material 17 is rotatable about the roller 15, so even if the roller 15 rotates, the material is held in a perpendicular state at all times to position the magnet 8 below the reflecting mirror 2 without fail. Therefore, even when the display device is used while tilted by more than a constant angle, the disorder of arc discharging due to convection can be corrected and the stable arc discharging is obtained.

Title: Skin packaging method
Inventor: MARUOKA ATSUMI
IPC: B65B11/52
Filed: 1987-09-17
Abstract: PURPOSE:To conduct skin packaging without wrinkles on the surface by placing a blocking plate between heater and film, after heating the film by the heater, covering an object to be packaged with the film, and at the same time, bonding the film on the surface of bass plate to complete packaging. CONSTITUTION:On the surface of a base plate 5, a heat seal layer 6 is formed; and an object to be packaged 4 is placed on the base plate 5. Above the base plate 5, a film 3 is kept horizontally; above the film 3, a heater 1 through a blocking plate 2 is arranged. The plastic film 3 is heated by operating the heater 1. Heating efficiency for the area under the blocking plate 2 becomes lower compared to the rest of the base plate; and the area excepting the part under the blocking plate 2 is further heat softened. By covering the object to be packaged with the heated film, and at the same time, heat sealing the film the surface of the base plate 5, the object to be packaged can be packaged. The upside of an object to be packaged 4 is hardly heated, therefore, wrinkles do not occur on the film and a fine looking packaging can be conducted.

Title: Ultrasonic wave measuring instrument for ophthalmology
Inventor: NAKAMURA YUKITSUGU
IPC: A61B8/10
Filed: 1989-09-08
Abstract: PURPOSE:To obtain a precise measuring value by reducing an error due to irregularity on the surface of a cornea by providing a storage means to store a measuring signal obtained with a measuring means which detects length between parts in an eye-ball, and a selection means which finds the measuring value when the amount of deformation of the cornea due to the contact of an ultrasonic probe is minimized. CONSTITUTION:A transmitter/receiver 7a of the ultrasonic probe 7 emits an ultrasonic wave to the eye-ball of the eye E to be inspected, and also, receives ultrasonic reflection signals S1, S2, S3, and S4 generated due to the interface of a medium in the eye-ball, and stores them in a memory circuit part 24. At this time, since the cornea Ec becomes hollow a little, the axial length of eye i.e., a distance from S1 to S4 is reduced a little by pressing the ultrasonic probe 7. However, by depressing a push-button switch 19, the ultrasonic probe 7 is separated from the surface of the cornea Ec, and the ultrasonic reflection signal is switched to an interface signal S0 with the air. By detecting such switching, the ultrasonic reflection signals S1-S4 just before switching i.e., at a state where the minimum quantity of hollow of the cornea Ec can be obtained. Therefore, the measuring value between the parts in the eye-ball not including the error can be obtained by reading out and calculating the measuring signal at that time from the memory circuit part 24.
