Title: Electronic apparatus and video camera
Inventor: HAIJIMA HIDEKI
IPC: G03B17/02
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide an electronic apparatus improving the operability of adjustment electronic parts by providing a means deviating an input/output terminal to the outer side of armor parts and fitting it. SOLUTION: A spacer 22 is used as a deviation means 21 for deviating an input/output terminal 11 to the outer side of a rear panel 4 and fitting it. The spacer 22 is inserted between a fitting face lid and the rear face 4a of the rear panel 4 at the outer periphery of the female spring part 11b of the input/ output terminal 11. A nut 11c is fastened in a recessed part 23 formed in the outer periphery of an input/output terminal fitting hole so as to fix the input/ output terminal 11 to the rear panel 4. Thus, an interval between the rear faces 4a and 13a of the rear panel 4 and a wiring board 13 can be reduced to L-X by an amount equivalent to the board thickness X of the spacer 22 with such constitution. Thus, the plural adjustment electronic parts 12 mounted on the wiring board 13 can remarkably be brought close to the plural adjustment files 15 formed in the rear panel 4.  Then, operability at the time of executing an adjustment operation can be improved.

Title: Fluid shut-off valve
Inventor: SHIMIZU KUNIO
IPC: F16K17/36
Filed: 1979-11-05
Abstract: PURPOSE: To assure stable function of a fuel gas shut-off valve, by keeping its valve body stable through effective combination of magnetic suction with magnetic adsorption.  
     CONSTITUTION: A shut-off valve 2 is open, when a movable magnetic valve body 5 and a stationary magnetic member 4 are adsorbed to each other against magnetic force of a permanent magnet 6. As an AC current flows through a reset coil 7 while the valve 2 is open, the magnetic field produced by the coil 7 destroys the magnetic adsorption between the valve body 5 and the stationary member 4, so that the valve body 5 is seated on a valve seat 3b by means of the permanent magnet 6 to close the flow passage. The valve 2 is kept closed even after the current through the coil 7 is interrupted. As the permanent magnet 6 is shifted against a spring 8 toward the stationary member 4, the valbe body 5 is also shifted toward the magnetic member 4 until its end 4b magnetically adsorbs the valve body 5. The valve body 5 is kept adsorbed even after the permanent magnet 6 is returned to its original position.

Title: Recording reproducing combination with film magnetic head
Inventor: OMI KUNIO
IPC: G11B5/31
Filed: 1985-06-28
Abstract: PURPOSE:To improve the stability and the reproducing efficiency of the performance at the time of travelling by forming the grove at the surface facing other side at either of two magnetic layers for the recording head oppositely arranged and providing the magnetic layer at the groove and the magnetic resistance effect element on it. CONSTITUTION:At the time of recording, by energizing a coil electric conductor 36 formed by calculating the number of the coil which can be recorded to the recording media beforehand, the signal is recorded by the magnetic flux generated from the coil electric conductor. At such a time, since an MR element 33 is thin, saturation is executed, a nonmagnetic layer 37 with sufficient thickness exists in the lower direction of a groove 38, and therefore, almost magnetic flux flows at a magnetic layer 31, and the reduction of the recording efficiency does not occur. The signal is reproduced by the resistance change of the MR element 33 when the magnetic flux to flow from a gap G between a reproducing time magnetic layer 31 and a magnetic layer 32 pass through the MR element 33 and the magnetic layer 31 in the lower direction. The bias magnetic field necessary for reproduction can be obtained by energizing the coil electric conductor 36. Thus, the travelling time performance is stabilized and the reproducing efficiency is improved.

IPC: H01L39/00
Filed: 1991-05-17
Abstract: PURPOSE:To render a maximum cut-off magnetic field increased and averaged by fabricating a large magnetic shield wherein a plurality of small-sized superconducting thin films are laid, with the edges thereof partially overlapping each other, without a contact between the films, and wherein the films are attached to a substrate. CONSTITUTION:Attached to a square and plane substrate 2 are rectangular superconducting thin films 1a-1n which are arrayed with the edges thereof partially overlapping each other. A resilient alloy-based thin film is preferably used as the superconducting thin films 1a-1n. The films are attached together by means of an organic adhesive, for low temperature service, and the adhesive layer is sandwiched between the films to prevent a contact, at the overlapping portion thereof, between the superconducting thin films 1a and 1b. For instance, when a laminated Nb-Ti alloy is used as the film, it is possible to prevent a contact, at the overlapping portion, between the foils of the superconducting Nb-Ti alloys which are closely adjacent to each other by coating both surfaces of the laminated film with a foil of Al, thereby rendering a maximum cut-off magnetic field increased and averaged.
