Title: Magnetic recording medium
Inventor: NAGAI NOBUYUKI
IPC: G11B5/842
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain high regenerative output in a short-wavelength region and to suppress noise to a lower level by specifying the average thickness of an upper magnetic layer and major axis length and X-ray grain size of magnetic metallic powder. SOLUTION: This magnetic recording medium is constituted by applying a nonmagnetic coating material consisting of nonmagnetic powder, binder and org. solvent on a nonmagnetic base 1, thereby forming a lower magnetic layer 2. The upper magnetic layer 3 is thereafter formed by applying a magnetic coating material consisting of the magnetic metallic powder, binder and org. solvent on the lower magnetic layer 2 while this layer is not dry yet. The magnetic recording medium of a double layer coating type is thus obtd. The average thickness of the upper magnetic layer of such magnetic recording medium of the double layer coating type is regulated to 0.05 to 0.5μm, the major axis length of the magnetic metallic powder to 0.05 to 0.2μm and the X-ray grain size to 100 to 250 angstrom.  When the upper magnetic layer is formed to the small thickness in such a manner, the occurrence of incomplete erasure at the time of overwriting is substantially prevented and a good overwriting characteristic is obtd.

Title: Rotation angle detector
Inventor: ASAMI KATSUHIRO
IPC: G01B7/30
Filed: 1989-10-31
Abstract: PURPOSE:To secure an output signal always accurately corresponding to the angle of rotation by controlling the correction of an output signal from a Hall element by a correcting means to obtain an output signal with a reference peak value. CONSTITUTION:When the intensity of a magnetic field to the Hall element 2 is changed by rotating a rotor 1, an alternate voltage is outputted from the element 2. Then the output of the element 2 is amplified by an amplifier circuit 3, its high frequency noise is removed through a filter circuit 4 and the noise-removed voltage is applied to a waveform shaping circuit 5. Namely the voltage is inputted to a peak holding circuit 11 to hold the peak value of the output voltage from the circuit 4. On the other hand, the reference peak value with a prescribed voltage is previously set up by a peak value setting circuit 12, the reference peak value is compared 13 with the peak value of the output voltage from the circuit 4 and an amplification factor adjusting circuit 14 to be the correcting means is controlled in accordance with the compared result. The peak value of the output voltage from the circuit 3 is adjusted to the reference peak value by this control. Thus, the output signal of the circuit 5 goes a signal corresponding to the angle of rotation without being influenced by dispersion relating to the rotor 1 and the element 2.

Inventor: HAYASHIBARA KUNINORI
IPC: E02D3/10
Filed: 1986-11-29
Abstract: PURPOSE:To safely and exactly stop a bucket at a lower limit position by a method in which a speed-reducing start position and a lower limit position at the time of lowering the vertically movable bucket are set up in advance.

Then by applying heat and pressure to the upper and lower faces 41, 42 by a heating member, internal faces of the packaging material 10 are stuck to each other, and also the folded sides 37, 38 are stuck via the adhesive agent 43. Thus rims at both sides of the upper and lower faces 41, 42 become approximately flat, and also an edge seal 32 is made to all down.  Thereafter the packaging material 10 between film units 11 with lens is cut laterally to provide a packaging bag.

Title: Electrode processing of varistor
Inventor: OKADA KOICHIRO
IPC: H01C7/10
Filed: 1987-11-12
Abstract: PURPOSE:To make heat treatment needless for improving production efficiency in a manufacture line by reducing a varistor voltage change factor to the extent of being able to be put to practical use by impressing surge voltage at least of 5kV charged to the prescribed capacity. CONSTITUTION:Surge voltage is impressed on a nonohmic electrode given to the primary body surface so as to break an insulating layer for making the nonohmic electrode ohmic. Surge voltage of at least 5kV having small capacity, for instance, being charged to the capacity of 1000pF is impressed, for instance, five times. In this way, when surge voltage is at least 5kV, a varistor voltage change factor can be reduced to an extent able to be fully put to practical use under 5% of a varistor change factor without heat treatment. Accordingly, a varistor can be formed in a series of manufacture line so as to improve its production efficiency.

Abstract: PURPOSE: To reduce an error rate of a received optical signal by using a semiconductor light emitting element with a grating formed therein so as to increase considerably the output intensity of an FWM component. CONSTITUTION: An input optical signal pulse opt1 and a probe light opt2 are synthesized by an optical multiplexer 1 to be a synthesized light opt3 and collected by a lens 3 and the resulting light is made incident to a semiconductor light emitting element 10.
