Abstract:
A magnetic head slider suitable for a disk drive measuring 1.8 inches or less in disk size incorporates preventive measures against the decreases in lifting force that occur in small sliders with a slider width of 0.8 mm or less. The present invention improves the inclination margins of the flying slider in a rolling direction at the lowest flying point, and achieves low flying height and stable flying. The slider is constructed with stepped surfaces on the slider's leading-side flying surface formed up of shallow-grooved surfaces and a deep-grooved surface so that a trailing-side width W2 between the stepped surfaces is smaller than a leading-side width W1.
Abstract:
A magnetic head slider includes a magnetic head mounting surface, a slider rail surface, a step air bearing surface, and a negative pressure groove. The magnetic head mounting surface is arranged in a center area with respect to a width of the slider near an air flow-out edge on the slider and mounts a magnetic head. The slider rail surface has a first depth from the magnetic head mounting surface and its width on an air flow-in side for the magnetic head is wider that its width on an air flow-out side for the magnetic head. The step air bearing surface is formed on an air flow-in side of the slider rail surface and has a second depth from the slider rail surface. The negative-pressure groove which formed on an air flow-in side of the step air bearing surface and has a third depth from the step air bearing surface.
Abstract:
A magnetic disk device includes a magnetic disk, and a magnetic head slider. The slider has a magnetic head, a plurality of surfaces which are formed sequentially from an adjacent side to a magnetic disk, and a slider rail surface which is arranged near an air flow-out edge on a nearest surface of the plurality of surfaces. The slider rail surface includes a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side. The nearest surface of the plurality of surfaces is arranged only in a center area with respect to a width of the slider near the air flow-out edge and has a width substantially less than the width of the slider. An area of the long sideways rail surface is larger than an area of the lengthwise rail surface.

A dip coating method, in which a cylindrical member is dipped in a coating solution in a coating solution tank and the coating solution is coated on an outer peripheral surface of the cylindrical member by the cylindrical member being raised, includes the steps of: making the coating solution always overflow from the coating solution tank; dipping the cylindrical member into the coating solution through an opening portion of a cover which is provided above a surface of the coating solution in the coating solution tank, and which has the opening portion through which the cylindrical member can pass, and which has a plurality of plates which are disposed at intervals in a vertical direction; and raising the cylindrical member.
Abstract:
A negative pressure flying head slider includes an air bearing surface of a substantially rectangular shape disposed in opposed relation to a rotating magnetic disk. One side rail of the slider is adapted to be located at an outer periphery-side of the magnetic disk when the slider is mounted on a magnetic disk device, and has an inflow-side side rail portion which is disposed at an air inflow end-side of the slider, extending generally parallel to the longitudinal direction of the slider, and an outflow-side side rail portion which is disposed at an air outflow end-side of the slider, extending in a direction of a yaw angle. The angle of the outflow-side side rail portion with respect to the inflow-side side rail portion is greater than the maximum value of an absolute value of the yaw angle. The slider further includes a recess defined by a cross rail and the side rails, and a slit formed in the cross rail to permit the recess to communicate with the air inflow end of the slider. A magnetic transducer is provided at that portion of the slider disposed adjacent to the air outflow end of the slider.
Abstract:
An image formation cartridge employed to a printer includes a movable image formation sheet supported between a pair of rotatable shafts, a rotatable ink applying roller unit contacting the image formation sheet and an ink feeding unit for feeding ink from an ink storing container to the ink applying roller unit. The image formation sheet may be wound on one of the pair of rotatable shafts as the shafts rotate in the same direction. Ink may continuously be applied to the image formation sheet through the ink feeding unit and the ink applying roller unit as the shafts rotate.
Abstract:
A sheet reverse apparatus for reversing a paper sheet discharged from an image forming apparatus has a mounting mechanism fixed to the image forming apparatus, and a power transmission mechanism. The power transmission mechanism is engaged with an output gear coupled to a drive source of the image forming apparatus, and transmits a driving force from the image forming apparatus to an input gear. The power transmission mechanism has a swingable plate and a spring for biasing the swingable plate in one direction. A movable gear meshed with the input gear and rotatable therearound is axially supported on the swingable plate. When the sheet reverse apparatus is mounted on the image forming apparatus, driving power from the sheet reverse apparatus can be supplied from the image forming apparatus through the input gear and the power transmission mechanism.
