A magnetic head support mechanism comprises a beam portion and a mount for connection to an actuator, which are integrally formed of a ceramic material. The beam portion has a magnetic head supported on a free end side thereof, which magnetic head comprises a magnetic head element and a magnetic head slider. The beam portion has at a part thereof a curved portion which is formed by spontaneous deformation due to internal stress. The integrated magnetic head support mechanism thus provided can be easily handled similarly to a conventional stainless-steel magnetic head support mechanism.

An optic rotation sensing apparatus includes a light source emitting light. The light emitted from the light source is transmitted to a sensing loop which provides a phase difference between opposite-direction light waves in response to a rotation. Return light outputted from the sensing loop is transmitted to a photodetector. A device modulates a phase of light propagating in the sensing loop. Another device depolarizes light propagating in the sensing loop. The invention further controls and processes an output signal representing the output of the photodetector at a phase at which a level of an AM noise component of the output signal is minimized.

A flying head slider has a slider body in which gas bearing rails are formed on a surface thereof disposed in opposed relation to a recording medium. A bleed portion is also provided at the surface of the slider body between a pair of gas bearing rails. The bleed portion is composed of at least a rectangular-shaped deep bleed portion in which the pair of longer sides thereof are directioned in parallel to the longitudinal axis direction of the gas bearing rails.

The invention designed to improve the precision in determining the position of the magnetic head and to enable more stable maintenance of the gap between the transducer and the recording disk is characterized in that the flange provided to the transducer supporting arm is made lower in height on the rigid arm side than on the magnetic head side.

A pulsation damper mounted in a fuel chamber (23) of a high-pressure fuel pump (20) is provided with a diaphragm (11) having a flat section (11a) displaced when fuel pressure is applied thereto, a pump cover (10) for supporting the diaphragm (11), and a gas chamber (12) formed by the diaphragm (11) and the pump cover (10). Pressure pulsation occurring in the fuel chamber (23) is suppressed by displacement of the flat section (11a). The diaphragm (11) is formed in a closed-bottomed tubular shape with the flat section (11a) located at the bottom and has a projection (11b) provided to the periphery of the flat section (11a) and projecting to the side opposite to the pump cover (10). A tubular peripheral section extending from the outer periphery of the projection (11b) so as to be vertical to the flat section (11a) is fitted over the pump cover (10). The externally fitting portion of the tubular peripheral section is a joint section (11c) joined to the pump cover (10).

In one embodiment, a method of manufacturing a magnetic disk includes rotating a magnetic disk, supporting a floating head on the rotating magnetic disk, the floating head having a slider body and an element unit formed on a trailing edge of the slider body, contacting a floating surface of the slider body with the magnetic disk, and protruding a portion of the floating head toward the magnetic disk due to application of power to a heater element within the element unit, wherein the element unit is positioned away from the magnetic disk. In another embodiment, a floating head includes a slider body comprising AlTiC, an element unit positioned on a trailing edge of the slider body, the element unit having an initial recess amount of at least about 4 nm, and a heater element positioned within an alumina protective film of the element unit.

A silicon manufacturing apparatus is disclosed as having a reactor tube (10) in which reaction occurs between zinc and silicon compound, zinc supply pipes (30, 30′) having heating portions to heat zinc for generating zinc gas and zinc ejecting portions ejecting and supplying zinc gas to the reactor tube, a zinc feeding section (40A, 40B) feeding zinc into the zinc supply pipes, a silicon compound supply pipe (50, 50A, 50B, 50C, 50c, 54, 57, 90) having a silicon compound ejecting portion to eject and supply silicon compound gas to the reactor tube so as to allow silicon compound gas to flow from a lower side to an upper side in the reactor tube, and a heating furnace (20) disposed outside the reactor tube to define a heating region (a) accommodating therein a part of the reactor tube, the heating portion and the zinc ejecting section for heating the same so as to allow the reactor tube, through which zinc gas and silicon compound gas flow, to have the temperature distribution such that a temperature closer to a central axis (C) of the reactor tube is lower than that closer to a side circumferential wall of the reactor tube.
摘要:
A compact slider has a reduced area of bearing surfaces, thus substantially decreasing a lifting force obtained through an air bearing characteristic. In one embodiment, a shallowly grooved surface and air bearing surfaces are disposed on an inflow side of a bearing surface of a slider. The air bearing surfaces are connected to each other through a connection air bearing surface. Side shallowly grooved surfaces are respectively disposed rearward of the air bearing surfaces. The side shallowly grooved surface extends up to a point near an outflow end. A center air bearing surface is disposed on the outflow end of the slider. A magnetic head is mounted on the center air bearing surface. A center shallowly grooved surface is disposed on an inflow side of the center air bearing surface. A deeply grooved surface is disposed at a center of the bearing surface. No cutting margins are provided on both sides of the slider. The air bearing surfaces on the inflow side therefore reach end faces in a width direction of the slider.
