Title: Magnetic head
Inventor: TERASONO KOJI
IPC: G11B5/23
Filed: 1988-12-26
Abstract: PURPOSE:To satisfy the resolution and the overwrite characteristic by providing a high-saturation magnetic flux density alloy thin film and a low-saturation magnetic flux density amorphous thin film on surfaces facing a gap part of cores. CONSTITUTION:A core 1 whose surface facing the gap part a low-saturation magnetic flux density amorphous thin film 5 is formed on and a core 2 whose surface facing the gap part a high-saturation magnetic flux density alloy thin film 7 is formed on are provided. In this case, the saturation magnetic flux density of the low-saturation magnetic flux density amorphous thin film is 1,500 to 3,000G, and cores 1 and 2 are joined into one body with a silicon oxide nonmagnetic part 6 between them. That is, the low-saturation magnetic flux density amorphous thin film 5 is magnetically saturated to function as a part of the gap at the time of recording and a strong magnetic flux is impressed from the high-saturation magnetic flux density alloy thin film 7 then. At the time of reproducing, the low-saturation magnetic flux density amorphous thin film 5 functions as a part of the core 1 and reproducing with a narrow gap is performed. Since the nonmagnetic part 6 is made of a silicon oxide nonmagnetic material, reaction between the nonmagnetic part and metal is not caused. Thus, the overwrite characteristic and the resolution are satisfactory and free from degradation.

Title: Door device foe elevator
Inventor: MATSUYAMA TAKESHI
IPC: B66B13/30
Filed: 1990-11-30
Abstract: PURPOSE:To shield a window at the time of no cage existing on a floor so as to remove unpleasant-uneasy feelings from users by providing a cage stop door window with a shielding device opened automatically only at the time of the cage arriving at the floor interlockingly with a cage position indicating lamp on the hall. CONSTITUTION:Upon the arrival of a cage at a floor, a current is applied to a drive unit 5 simultaneously with the lighting of the floor lamp of a cage position indicating lamp, so that a motor 11 starts its rotation to push up a shielding plate driving bar 10. Since a line connecting the fulcrum of the shielding plate 4 to a force point has a certain angle in relation to the face of the plate 4, the force point does not reach the lower dead center even in the closed state of the plate 4. A driving arm 8 therefore pushes the driving bar 10 up without force, and the plate 4 connected to a link by the push-up of the driving bar 10 is rotated/opened all at once. At the fully opened time of the plate 4, a gear 19 pushes a limit switch 14 up, so that the motor 11 is stopped, and simultaneously, an electromagnetic brake 12 locks driving mechanism in the braking state to hold the fully opened state of the plate 4. When the cage passes through, the power source is cut off, the brake and the clutch are released, and the plate 4 is closed by its self-weight.

CONSTITUTION:A high speed response solenoid valve V disposed at the intermediate portion of a hydraulic pipe connecting an operation valve 11 with the driving motors M of right and left crawler transporters 1 is opened or closed to move the tractor or stopped depending upon the row detection result of a row detection sensor 5. When one of levee access detection sensors 4 detects the access of the levee, a valve V disposed at an intermediate portion of a pipe connecting the other side operation valve 11 and a driving motor M of a crawler transporter 1 is closed and the other side crawler 1 is automatically turned. When the levee access detection sensors 4 on both the sides simultaneously detect the access of levees, the valves V disposed at the intermediate portions of the hydraulic pipes connecting the valves 11 with the crawlers 1 are alternately closed to simultaneously stop both the crawlers 1 for stopping the travel of the tractor.

Title: Method of generating magnetic field for mri, and mri device
Inventor: SATO KAZUHIKO
IPC: G01R33/3815
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To hold a uniform magnetic field by generating an MRI magnetic field in a prescribed area, and generating a cancel magnetic field for correcting the magnetic field fluctuation caused in the prescribed area by the movement of a magnetic cold storing agent used for the cooling of a superconductive coil. SOLUTION: When a dispressor of magnetic cold storing agent is reciprocated within a cylinder, a disturbance magnetic field component is changed in intensity. A signal synchronous with the movement of the dispressor is provided by a compressor CP, so that a cancel magnetic field for canceling the disturbance magnetic field component is generated from this signal. Namely, a necessary cancel magnetic field is determined by calculation in reference to the signal synchronous with the movement of the dispressor received from the compressor CP by an arithmetic part CAL, and a cancel magnetic field driving part CMF supplies a current for forming the cancel magnetic field according to the arithmetic result to a canceling coil CC. Thus, the disturbance magnetic field component is canceled by the cancel magnetic field so as not to have an effect on a tomographic image.

Title: Over-cap for wide mouth container
Inventor: YOSHIDA HITOAKI
IPC: B65D51/18
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent an over-cap from being deeply fitted to a wide mouth container during a plug driving stage in which the over-cap is fitted to the wide opened container. SOLUTION: An upper inward-annular protuberance 9 is projected more largely than an upper outward-annular protuberance 2, and a lower surface 9a of the upper inward-annular protuberance 9 is formed as a flat surface. Since a deformation resistance of the upper inward-directed annular protuberance 9 is increased and a friction with a lid 3 is increased, it is possible to prevent the upper inward-annular protuberance 9 from riding over the upper outward-annular protuberance 2 of a wide opened container 1 when the plug is driven.
