Abstract:
A magnetic head slider, for sliding on a magnetic disk, which has a leading edge, a trailing edge, an air bearing surface having a front step bearing of submicron depth made from the leading edge, and a rail surface made from the front step bearing. A negative pressure recess which is deeper than the front step bearing, is formed as a recess from the rail surf ace, and a side step bearing with a depth identical to that of the front step bearing is made from the rail surface. Side padB are provided which each have a width W and length L, wherein W is greater than L.
Abstract:
A magnetic head slider having 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 including a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side, has a magnetic head. An area of the long sideways rail surface is larger than an area of the lengthwise rail surface.
Abstract:
In a magnetic disk unit, in the control of a load/unload function of a magnetic head relative to a magnetic disk, the magnetic disk and the magnetic head are prevented from contacting each other and damage thereto is avoided by utilizing a shallow dual-step subambient pressure slider and carrying out loading/unloading at a rotational speed lower than a rated rotational speed of the normally operated magnetic disk at which writing and reading (R/W) of data to and from the magnetic disk by the magnetic head is normally carried out.
Abstract:
A mouth piece unit (6) for a semi-closed type breathing device (1) in which when pressing down a start button (102), the entirety of a movable assembly (70) moves and an external opening (73) opens, whereby a mouth piece (62) is caused to protrude, allowing a diver to hold it in his/her mouth. Since the movable assembly (70) is held at that position even if the start button (102) is restored, an inhalation gas supply valve (21) is held in an open state by an engagement bar (74), whereby the supply of inhalation gas is continued. When the mouth piece (62) comes out of the mouth of the diver, the movable assembly (70) is restored and the external opening (73) is automatically closed, thereby preventing water from entering the inside therethrough from the outside. To drain water, when the start button (102) is kept pressed down, purge gas is supplied from a purge gas supply valve (22), a water draining opening (120) opens, and a breathing air hose connecting port (61a) is closed, this allowing water to be automatically drained. Thus, it is possible to realize a mouth piece unit for a semi-closed type breathing device that can easily be used by a novice.
Abstract:
A micromilling device includes a milling chamber, at least one nozzle for injecting a stream of solid particles to be milled into the chamber in a predetermined path, and impact elements positioned in the path for impacting the stream of solid particles.
Abstract:
In an ophthalmological measurement method and apparatus, a laser beam of predetermined diameter is projected to the eye fundus and movement of a speckle pattern formed by light scattered by blood cells in blood vessel is detected by a photosensor as fluctuation in speckle light intensity to produce a speckle signal. The speckle light intensity will fluctuate more rapidly with a smaller output from the photosensor when cell velocities are high, while a low cell travel speed will decrease the lowering of the output therefrom. The speckle signal is integrated to produce an integrated speckle signal which is evaluated in terms of a rate of change to discriminate edges of a blood vessel. The integrated speckle signal is used to identify the blood vessel for automatic tracking of the blood vessel or for measurement of its diameter.

The speckle light intensity will fluctuate more rapidly with a smaller output from the photosensor when cell velocities are high, while a low cell travel speed will decrease the lowering of the output therefrom. The speckle signal is then processed to derive therefrom its center of gravity, which is taken as a center of a blood vessel to identify the blood vessel. This enables the blood vessel parts to be identified with high accuracy and to be tracked automatically.
Abstract:
An injection apparatus of a plunger type for injecting reinforced materials such as BMC is of a single barrel type or a double barrel type having a rotatable plunger disposed in the barrel. A check valve device for preventing a back flow of the materials in a metering process is provided such that it is closed when the plunger is actuated to move axially for injection.
Abstract:
A feed for domestic animals containing saccharides mainly composed of fructooligosaccharide is particularly effective for growing young domestic animals. The feed can remedy the scours or loose passage frequently occuring young domestic animals in the weaning period of young animals and remarkably increase the weight of the young animals.
Abstract:
A magnetic-recording-disk test-head. The magnetic-recording-disk test-head includes a slider, a test pad and a slider-surface-shape control mechanism. The slider includes a leading edge and a trailing edge. The test pad is disposed at a trailing-edge side of the slider and is configured to remove and to detect asperities on a magnetic-recording disk. The slider-surface-shape control mechanism is configured to change a shape of an air-bearing surface of the slider and is disposed at a leading-edge side of the slider.
