Title: Magnetic disk and magnetic disk device
Inventor: OYANAGI HIDEKI
IPC: G11B5/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic disk device by which information is recorded and reproduced stably and which increases a recording density by a method wherein an information recording area on a magnetic disk on and from which the information is recorded and reproduced by using a magnetic head mounted on a head slider is formed of an uneven part. SOLUTION: An information recording region on a magnetic disk 3 on and from which information is recorded and reproduced by using a magnetic head 8 mounted on a head slider 6 is formed on an uneven part. Then, the disk 3 is set on a magnetization device so as to be rotated and run, and a magnetic film in a recess and that in a protruding part on the disk are magnetized in the vertical direction. When the levitation amount of the slider 6 is extremely small, an air film on the protruding part is very thin, and it loses the property of an air spring. On the other hand, an air film on the recess is still sufficiently thick, it holes the property of a hydrodynamic air spring, and the slider 6 can be levitated stably so as to be low.  In addition, since a guard band is formed as a physical recess with reference to a data track, the blur of a signal is small in a recording operation and a reproducing operation, a cross talk is reduced, and a recording density is increased.

Title: Double pendulum clock
Inventor: NAKAMURA NORIHIKO
IPC: G04B45/00
Filed: 1983-08-17
Abstract: PURPOSE:To obtain the excellent self-actuation of pendulums without providing any large driving force applying mechanism especially by fixing interlocking magnets to supports for the 1st and the 2nd pendulum rod comps. so that their polarities are coincident with each other. CONSTITUTION:The interlocking magnets 30 and 32 are fixed to the 1st pendulum rod comp. 16 and the 2nd pendulum rod comp. 18 at the opposite positions so that the polarities are coincident with each other. Consequently, the 2nd pendulum rod comp. 18 oscillates according to the oscillation of the 1st pendulum rod comp. 16 with mutually repulsive magnetic force generated between both magnets and the strongest still magnetic bypass is caused in an initial pendulum still state, thereby elevate the actuation characteristics of the pendulums. Namely, the mutually repulsive force operates between both magnets 30 and 32 by arranging the interlocking magnets 30 and 32 with the same polarities, and this mutually repulsion is maximum when the pendulums are still. Consequently, a still magnetic bias which separates the pendulums is generated between the both in the pendulum still state and the mutually repulsion occurs between both magnets all the time to attach the self-actuation by applying extremely small driving force to a driving coil 28.

IPC: F16D41/08
Filed: 1989-06-12
Abstract: PURPOSE:To always enable constant changeover of transmission torque by engaging an engaging element with a portion between a casing and a first shaft while utilizing twist of a torsional bar, and switching a rotational torque between the first shaft and the casing. CONSTITUTION:When front wheels are slipped and the rotation of a first shaft 4 is faster than that of a casing 1, the rotational difference is generated between a second shaft 2 and the casing 1. Then, difference is generated in movement of viscous material on a bottom side of an inner port 3 of a pressurized plate side. Shearing resistance is caused inside a viscous layer 20 to apply force which is stopping the rotation of a pressurized plate 14 and the shaft 7. The shaft 7 is slipping to the shaft 4, and a torsional bar 9 is twisted. When the rotation of the casing 1 is agreed with that of the shaft 4, the torsional bar 9 is twisted back, and force resetting to the original condition is generated against the shearing resistance of the viscous layer 20. An engagement element 30 is pressed in a circumferential direction by means of contact to a cylindrical surface 22, a clutch is disconnected, and the casing 1 is rotated independent on the shaft 4.

Filed: 1988-06-21
Abstract: PURPOSE:To maintain a main discharging capacitor at an almost fixed charging voltage by providing a switching circuit which shifts a switching element to a state where the element can be turned on in response to the command signal from a camera. CONSTITUTION:Upon receiving a prescribed command signal from a camera, a switching element 28 is set to a state where the element 28 can be turned on and, when the turning on and turning off of the element 28 are repeated, a DC-DC converter continues oscillation until the charging voltage of a main discharging capacitor 33 reaches a specific value. When the capacitor 33 is charged to the specific charging voltage value, a monitor circuit is actuated by the rise of the output voltage of a boosting transformer 21 and the oscillation of the DC-DC converter is once stopped. Since the output voltage of the transformer 21 is an AC-like voltage, the monitor circuit is immediately restored to an oscillation enable state after once stopping the operation. While the DC-DC converter repeats the oscillation stop and oscillation restarting, the charging voltage of the main discharging capacitor 33 can be maintained at an almost prefixed constant voltage value.

Abstract: PURPOSE:To prevent a titled filtering body from clogging, and to improve the removing rate, by laminating plural filtering units, formed by arranging oppositely porous anode and cathode plates and disposing a porous dielectric between the plates through an oil-permeable spacer. CONSTITUTION:When an electric power is supplied from a high-voltage electric- power generating device 5 after attaching a filter 3 to an adapter and flowing an oil in the directions of the white and black arrows, a cylindrical member 2 is impressed into negative, and the oil is flowed through a filtering body 1 in the direction of the real arrow line and also a high voltage electric field is formed between plate electrodes 14a, 14b. As most fine particles of carbon incorporated in the oil are charged into negative, only the fine carbon particles are attracted to the anode plate 14a as shown by the dotted arrow lines and are captured by a charged dielectric plate 13 on the way to lose their negative charges, thereby the particles are stuck to the plate 13 to be held by its without being carried away by the oil. At a part where a large amount of carbon particles deposit, the oil flows into adjoining spacers, then an increase of the flow resistance of oil is prevented as a whole.
