Title: Perpendicular magnetic recording medium
Inventor: KITAHARA YOSHIMI
IPC: G11B5/706
Filed: 1987-02-12
Abstract: PURPOSE:To obtain a perpendicular magnetic recording medium which has high practicability and can deal with high-density recording by specifying the conditions of a supporting substrate, underlying layers, recording layers, protective layers and lubricating layers. CONSTITUTION:This recording medium is constituted by forming the underlying layers 2, the recording layers 3, the protective film layers 4 and the lubricating layers 5 successively on the supporting substrate 1. The substrate 1 is a high- polymer film having 300-1,000kgf/mm<2> Young's modulus, <=0.02mum surface roughness Rmax and >10<4> pieces/mm<2> filter packing density. The underlying layers 2 consist of a 'Permalloy(R)' film having 8-20(Oe) coercive force in the intra-surface direction and 0.3-0.5mum film thickness. The recording layers 3 consist of a Co-Cr alloy film having <=0.2mum film thickness and >=400(Oe) coercive force in the perpendicular direction. The protective layers 4 consist of an inorg. oxide film having >=700 Vickers hardness and <=0.02mum film thickness and the lubricating layers 5 consist of fluorocarbon having a polar group. Upgrading of the perpendicular magnetic recording medium adequate for the high-density recording up to a practical level is thereby permitted.

IPC: H03F3/60
Filed: 1987-02-12
Abstract: PURPOSE:To make the impedance when viewing a bias power supply from an input terminal always constant by connecting a 1st distributed constant line whose one terminal is connected to ground or the like via a capacitor and a 2nd distributed line whose one terminal is opened via a resistor. CONSTITUTION:A microwave from an input terminal 8 is divided equally by a T-branch line 14, propagates through the 1st and 2nd distributed lines 9, 10 at the same amplitude and phase without being consumed by resistors 11, 12 connected between the lines 9, 10, are reflected totally at a bias power terminal 7 of the lines 9, 10 and goes toward the terminal 8. In this case, one terminal of the line 9 toward the terminal 7 is connected to ground via a capacitor 13, short-circuited, and the terminal of the line 10 is opened, then the reflected microwave of the lines 9, 10 is in the opposite phase and consumed in the resistors 11, 12 and is not returned to the terminal 8. Thus, the impedance in viewing the terminal 7 from the terminal 8 is always constant independently of the impedance of the bias power supply and the change in the amplifier characteristic by the bias power supply is prevented.

Abstract: PURPOSE:To suppress picture blur even if an inexpensive oscillating gyroscope is used, by detecting the shock applied to a photographing means and cutting off the output of an angular velocity detecting means for a prescribed time if the shock exceeds a prescribed value. CONSTITUTION:If such shock is applied to an optical system 107, an image pickup device 108, and a gyroscope 103 of a photographing device 100 that the output of the gyroscope is abnormal, an output 110 of a shock detecting sensor 101 is changed immediately.

When the signal 110 is increased to reach a set value er, a switch circuit 102 cuts off the output of the circuit 104 immediately. Though the shock is attenuated with time and the signal 110 is reduced, the device 103 and the circuit 104 cause transient phenomena and continue to output abnormal outputs. The circuit 102 connects the output of the circuit 104 to a picture rocking suppressing signal generating circuit 105 again after transient phenomena are terminated and outputs are settled, and an optical axis compensating mirror 106 is controlled by the output of the circuit 105 to compensate the picture blur.

IPC: C01G49/00
Filed: 1989-02-10
Abstract: PURPOSE:To highly concentrate the solution of ferrite raw material in the production process thereof where iron (II)-contg. waste water is neutralized with an alkali agent to produce hydroxide, which is concentrated to produce the source material of ferrite, by adding a specific amt. of iron (III) in the neutralization process. CONSTITUTION:Calcium hydroxide is added to the iron (II)-contg. waste water in a neutralization tank 1 to produce a precipitate slurry contg. iron (II) hydroxide, which is separated from the liquid in a separatory thickener 3. The obtd. iron (II) hydroxide is used as the source or a part of the source material of ferrite. In this process, a portion of the iron (II) hydroxide obtained in the thickener 3 and iron (III) is added to the neutralization tank 1 in a manner that the amt. of iron (III) in the tank 1 is less than twice by weight as that of iron (II). Thereby, the solution can be concentrated to high concentration, so that the capacity of the reaction tank to produce ferrite can be reduced, which saves not only the area for installation but energies required for mixing, heating, etc.

Inventor: IKEDA AKIRA
IPC: H02P29/00
Filed: 1981-03-05
Abstract: PURPOSE:To form a small-capacity coupler for motor and load by providing a speed compensator with an integrating circuit. CONSTITUTION:When a clutch 3 is in open mode, a motor 22 rotates at a speed of NM and the control voltage applied to a static leonard 2 is EC1. Next, with a load 4 running at a high speed connected to the static leonard 2 by closing the clutch 3, the rotating speed of the motor 22 increases in accordance with the rotating speed of the load 4. However, the number of revolutions of the motor 22 is held at NL as the control voltage is maintained at the value EC2 controlled by voltage regulator diodes 16. When a predetermined period elapses under this condition, selectors 18, 19 are switched by the control signal from a speed comparator 6. At that time, a feedback capacitor 15d is charged through a parallel circuit of feedback resistors 15a, 15b. Therefore, the control voltage EC2 applied to the static leonard 2 is slowly changed to the voltage EC3 corresponding to a low-voltage limiter 17.

Filed: 1995-01-30
Abstract: PURPOSE: To safely guide a toe at the time of moving the toe from the accelerator side to the brake side by providing a guide plate at the accelerator pedal side side-face on a brake pedal. CONSTITUTION: A guide plate 2 is fixed to the arm 9 of a brake pedal by a bracket.

Abstract: PURPOSE:To improve the output and efficiency of a transverse excitation type pulse laser oscillator by starting the charging of a capacitor connected in parallel with a main electrode pair, operating a reserve ionization mechanism after a predetermined time lag and making the rise of the reserve ionization mechanism faster than that of voltage between the main electrode pair. CONSTITUTION:A signal from a trigger control circuit 13 is transmitted over a pulse discharging circuit 10 for main discharge first. Consequently, the pulse charging of a peaking capacitor 4 is started, and voltage Vg between main electrodes 1, 2 begins to rise. A signal is transmitted over a pulse charging circuit 12 for reserve ionization from the trigger control circuit 13 after a fixed time passes after Vg begins to rise, and the charging of a peaking capacitor 11 for spare ionization is started after tp time after the application of voltage between the main electrode pair 1, 2. Arc discharge is generated between the reserve ionization electrode pair 3a, 3b, and reserve ionization is conducted extending over the whole regions of a discharge excitation section 5 by the generation of ultraviolet beams 6. Voltage Vg between the main electrodes 1, 2 reaches break-down voltage VB between the main electrodes 1, 2 reaches break-down voltage VB and main discharge is started, and laser beams are projected in the direction of an optical axis 8. Accordingly, the reserve ionization is performed after the rise of Vg, thus increasing break-down voltage VB.
