Title: Floating head load mechanism
Inventor: HASHIMOTO MASANOBU
IPC: G11B21/21
Filed: 1988-02-22
Abstract: PURPOSE:To execute smooth head loading by holding a floating head slider in a non-contact condition when a magnetic head is stopped and loading the floating slider when a magnetic disk medium achieves a rated revolving speed. CONSTITUTION:When a medium 7 of the magnetic disk is stopped, a lubricating surface 1a of a floating head slider 1 is dispossed so as to have the positive pitch angle of a fine value to the surface of the medium 7 and the interval of 0.5mm around, for example, is kept between the surface 1a and a disk 7 surface. Next, in a stage that a distance between the surface 1a and the medium 7 surface is comparatively large during an access, forcible deplacing force by piezoelectric actuators 5a and 5b is operated to the slider 1 only. However, when the distance is decreased, negative pressure goes to be occupational for the force to be operated to the surface 1a. Accordingly, the surface 1a is attracted to the medium 7 surface and the slider 1 smoothly approaches the medium 7. When the distance goes to a sub-micron area, for example, since the positive pressure of the surface 1a is clearly generated, the balance between positive and negative pressures of the surface 1a is kept and the floating head slider is loaded.

Title: Drive circuit for mos field-effect
Inventor: YAMAGUCHI KOJI
IPC: H03K17/687
Filed: 1994-03-11
Abstract: PURPOSE:To decrease the switching loss by connecting a diode and a coil, whose polarities are aligned in a contain direction, to both ends of the secondary winding of a transformer in series, charging the current through the secondary winding of the transformer when a MOS field-effect transistor is ON, and discharging the current when the transistor is OFF. CONSTITUTION:When a transistor 1 is turned ON, the voltage V2 is induced in the secondary winding of a transformer 2, and a MOSFET3 is turned ON. Power is exchanged with a main transformer 4. Meanwhile, the current I1, which is divided from the current I0 of the secondary winding of the transformer, is charged into a coil L1 through a diode D1. When the transistor 1 is turned OFF, the secondary voltage V2 of the transformer 2 is inverted, and the MOSFET3 is turned OFF. At the same time, the coil L1 starts the discharging, and the electromagnetic energy accumulated in the secondary winding of the transformer starts discharging. Therefore, the switching time from ON to OFF becomes quick.

Filed: 1990-02-20
Abstract: PURPOSE:To reduce variance in toner temperature at a film separating position and also to prevent irregularities in an image and off-set by respectively specifying a distance to a film bend and the radius of curvature of the bend. CONSTITUTION:The distance A from the center of a nip to the bend where the film 5 is separated is set <=25mm. Thus, the film is separated before the toner is cooled and solidified, so that gloss is not generated on a toner image. And also, a difference between the temperature in the nip and the temperature at the separation point is small, so that the variance in the toner temperature at the separation point is small, so that the variance in th toner temperature at the separation point is small. And the radius of curvature B of the bend is set <=4mm. Thus, the toner still being in a soft state can be separated from the film 5 because of the stiffness of a recording material, so that the irregulari ties in the image and the off-set can be prevented.
