Title: Vacuum seal vessel
Inventor: NOMURA MINORU
IPC: B65D51/16
Filed: 1990-06-25
Abstract: PURPOSE:To completely insulate the inside from the outside, by closely sealing a cover and a vessel body via a packing due to the differencial pressure between the inner and outer sides of the vessel. CONSTITUTION:A packing 6 is compressed and a vessel is also deformed according to its deforming ability by compression of a cover 1 or the vessel body 3 of simultaneous compression of the cover 1 and the vessel body 3, and a part of the air in the vessel is discharged through an air vent 5. Upon halt of the compression, a check valve 4 works on recovering of the packing 6, the cover 1, and the vessel body 3 to close the air inflow from the outside and to make the inside of vessel to be negative in pressure. The cover 1 and the vessel body 3 adhere closely through the packing 6 due to the pressure difference of the inside and the outside of the vessel. When the check valve 4 is raised, the negative pressure is relieved and the cover is opened. In this way, as the inside of the vessel can be completely insulated from the outside, the foodstaff can be stably preserved and it does not absorb odors of a refrigerator and also it does not discharge outward the moisture and odors of the contents.

Title: Production of magnetic recording medium
Inventor: YAMAGUCHI SEIJI
IPC: C23C14/56
Filed: 1985-07-26
Abstract: PURPOSE:To obtain high coercive force and excellent input and output characteristics and erasing current characteristic and to decrease the difference between the forward and backward characteristics of the traveling direction of a tape by specifying the position of the vapor source of a ferromagnetic metal. CONSTITUTION:The vapor source is disposed in the position in the range where the effect of magnetic anisotropy remarkably appears, i.e., in the position where an angle thetaa is >=15 deg. in order to render the substantial magnetic anisotropy to a thin metallic film layer in the stage of arranging the evaporating atoms of the columnar ferromagnetic metal on a high-polymer molding substrate and therefore the high coercive force is obtd. and the excellent input and output characteristic and erasing current characteristic are consequently obtd. The angle is at the same time set at -90 deg.<=thetab<=-10 deg. and 10 deg.<=thetac<=90 deg.; therefore, the incident angle eventually contains always >=10 deg. plus component and <=-10 deg. minus component. The effect of the magnetic anisotropy of the thin metallic film layer, i.e., the direction of the axis of easy magnetization and intra-surface coercive force are thereby maintained measurably evenly in both the forward and backward directions of the traveling direction of the magnetic tape, by which the difference in the input and output characteristics by the directions and the erasing current difference are reduced.

IPC: H01F38/28
Filed: 1991-07-09
Abstract: PURPOSE:To minimize the device size by using a small size iron core and a proper current detection method. CONSTITUTION:For a first method, an iron core 15 which shows weak coercive force of square shape in magnetic hysteresis curve, is used and an AC-excited coil 16 is wound around the thick part of this iron core 15. A high resistance 17 connected in series to this and an AC-excited power source 19 are provided and the iron core is exited by alternating current to both of positive and negative directions of the magnetic field to the saturation regions of the hysteresis curve with the same conditions. If a magnetic field generated by the detected current flowing in a conductor passing near the iron core 15 adds to it, then the phase of reversing the magnetic flux of the iron core changes. The change of the phase is detected through the detected current caused by the voltage induced by a detection coil 18 wound around the iron core 15 or the voltage across the AC-excited coil. For a second method, an iron core 15 having the Matteuci effect is used. Similarly to the first method, the change of phase reversing the magnetic flux of the iron core 15 is directly extracted through the voltage induced in the iron core 15 itself without using a detection coil.
