Title: Production of magneto-optical recording medium
Inventor: HORIKAWA MITSUHIRO
IPC: C23C18/12
Filed: 1987-07-10
Abstract: PURPOSE:To improve the uniformity on a medium disk by coating a coating liquid prepd. by diluting a specific metal alkoxide with a solvent onto a substrate, then subjecting the coating to heating, decomposing and crystallizing, thereby forming a perpendicular magnetic recording layer consisting of cobalt ferrite. CONSTITUTION:The coating soln. prepd. by diluting the cobalt ferrite of the cation of the atoms constituting the cobalt ferrite expressed by the formula CoFe2O4 with the solvent is coated on the substrate and thereafter, the coating is heated, decomposed and crystallized, by which the perpendicular magnetic recording layer consisting of the cobalt ferrite is formed. The compsn. distribution and film thickness distribution of the cobalt ferrite layer to be used as an information recording layer are thereby diminished and the uniformity of the medium disk is enhanced. The high-quality magneto-optical recording medium is thus obtd. at a low cost.

Title: Solenoid valve drive unit
Inventor: YUASA HIROYUKI
IPC: F16K31/06
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent any degradation in current control precision due to a change in solenoid valve resistance. SOLUTION: While a solenoid valve 14 is under full-duty control, a learned- resistance arithmetic part 18 estimates the resistance R-lrn of the solenoid valve 14 from a current Isol actually flowing through it. A learned-duty arithmetic part 19 next computes a duty value D-lrn from an equation: D-lrn=K.(VB 14/VBATT). (RSOL+R-lrn)/RSOL}+OFSET; where K is a factor, VBATT is a line voltage, VB14 is a reference voltage, RSOL is the reference resistance of the solenoid valve 14, and OFSET is a duty offset correction value. A corrected-duty arithmetic part 20 obtains as a correction value the difference between an actual or full duty value and the learned duty value D-lrn and uses this correction value for duty correction.

Title: Drive circuit and current direction switching circuit for n-channel mosfet
Inventor: ITO MAKOTO
IPC: H03K17/16
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To satisfactorily turn an FET on and off, even with a presence of difference of a ground potential in regard to a drive circuit which turns an n-channel MOSFET on and off, according to the state of an input terminal that is grounded and opened by a switching element of a control circuit. SOLUTION: A drive circuit of an FET (Tn) is composed of the NPN transistors TR T1 and T2 and the resistors R1 to R4 and turns the Tn on and off, according to voltage Vo of an input terminal which is grounded and opened by a switching terminal To of a control circuit. The drive circuit of such a constitution can increase the threshold of voltage Vo to turn on the TR T1, as long as the resistance value of the resistor R3 is increased and therefore can surely turn on the TR T1, even if the ground potential GND1 of the control circuit is higher than the ground potential GND2 of the drive circuit. On the other hand, the resistance value of the register R4 must be reduced if the resistance value of the R3 is increase. However, it is not required to especially reduce the resistance value of the R4, since the R4 needs only a sufficient base current to turn on the T2.  Thus, it is possible to reduce the current (ic) that flows to the control circuit, when the element To is turned on by increasing the resistance value of the R4.
