Abstract: PROBLEM TO BE SOLVED: To improve authentication judgement performance and visibility by recording fixed signals in at least two magnetic layers of magnetic layers in such manner that the fixed signals are formed by a magnetic field generated from signals recorded in order magnetic layers or by the magnetic field and he orientation magnetic field and that the fixed signals can not be rewritten, and recording different unrewritable fixed signals in an least two magnetic layers of the magnetic layers. SOLUTION: A first magnetic layer 2 capable of magnetic recording is formed by using magnetic powder such as γ-Fe2 O3 , Co-coated γ-Fe2 O3 , and Ba ferrite on a nonmagnetic substrate 1 and specified signals are magnetically recorded. Then a second magnetic recording layer 3 of a same component is formed on the first magnetic layer 2, and then a third magnetic layer 4 having different saturation magnetization characteristics is formed thereon. The coercive force of the magnetic powder in the first magnetic layer 2 is preferably controlled to three or more times of the coercive force of the magnetic powder in the second magnetic layer 4.  The third magnetic layer 4 is subjected to DC orientation treatment in a magnetic field higher than the saturation magnetic field in the parallel direction to the coating direction so as to form a fixed pattern with a different saturation magnetization effect.

Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To positively and safely vent gas while gas is prevented from being abruptly vented, and from being splashed onto human bodies and clothes, and let nails be dealt with safely. SOLUTION: An arrow-heat-shaped nail 2 having a groove engaged, which is a few millimeters in diameter, and tens of millimeters long, is erected vertically over the center of a pedestal 3 integrated with a cover, and is housed in the bottom in a semi-spherical shape of a spray can 1 so as to be integrated with a main body.

Abstract: PURPOSE:To prevent missing of a data at changeover of active/spare set by providing a preset terminal to a built-in FF and presetting an FF of a spare system in matching with the state of the active system. CONSTITUTION:A unipolar/bipolar converting circuit consists of an active circuit comprising an FF10, AND gates 11, 12, transistors (TRs) 13, 14 and a transformer 15 and of a spare circuit comprising an FF20, AND gates 21, 22, TRs 23, 24 and a transformer 25. A preset terminal PR is provided to the FFs 10, 20, a preset signal d0 of the FF10 is selected optionally, and a signal d1 presetting the FF20 is fed to the terminal PR at a leading of the output of the gate 11 in order to match the FF20 with the state of the FF10. Thus, when the output of the gate 11 is logical '1', the level of an output terminal Q2 of the FF20 is logical 1 and the output of the gate 21 goes to logical '1'. Since the polarity of the output bipolar waveforms of active and spare circuits is coincident, the uninterruptible switching is attained without data missing in the changeover of active/spare circuits.

Abstract: PROBLEM TO BE SOLVED: To obtain a disc drive employing a reverse rotation brake system for a spindle motor in which a driver circuit is protected against breakdown due to a regenerative current by realizing a pseudo short brake system in place of the reverse rotation brake system. SOLUTION: In a disc drive where a positive or negative polarity drive current can be generated from a power supply and supplied to a driver circuit 2 thence supplied, while switching the polarity, to a spindle motor 1 in order to apply reverse rotation brake thereto, the driver circuit 2 is protected against breakdown due to a regenerating current by interrupting or limiting source current supply thereto during reverse rotation brake of the spindle motor 1. Furthermore, overall power consumption can be reduced because power corresponding to current supply to the motor during reverse rotation brake is eliminated.
