An optical information recording medium contains a recording layer that includes: a recording area on which a cavity is formed as a recording mark as a result of an increase in temperature around a focal point after absorbing a recording beam converged for recording of information in accordance with the wavelength of the recording beam and from which, when a predetermined reading beam is emitted for reproducing of the information, the information is reproduced based on the optically modulated reading beam; and a non-recording area provided adjacent to the recording area to prevent the heat around the focal point from dispersing.

The invention provide the seating apparatus to be used on the chair of the horizontal sitting base plate in order to avoid the lower back pain. By sitting on the seating base plate tilted forward from 5 to 45 degree, the person can keep the angle between the spine and the thigh from 95 to 135 degree. As the seating apparatus is equipped with the knee front holder connected with the supporting part, which is connected with the seating base plate by the half fixed joint at an another end of the supporting part, the slip down of the body on the seating base plate is stopped by the knee front holder and the steady sitting is available.

A magnetic transducer head comprising a first magnetic core element and a second magnetic core element, each of the first and second core elements comprising a magnetic ferrite block and a magnetic metal thin film integrated with the magnetic ferrite block. These core elements having a first planar surface and a second planar surface. The magnetic metal thin film being provided on the second planar surface and having an edge thereof facing to the first planar surface, and the second planar surface being slantly provided with respect to said first planar surface. These core elements being bonded together to form an operating magnetic gap between the edge of the magnetic metal thin film on the first core element and the edge of the magnetic metal thin film on the second core element. The magnetic metal thin film on the first core element or the magnetic thin film on the second core element is formed in one common plane.The magnetic metal thin film may be formed of the ferromagnetic metals including Fe--Al--Si alloys, amorphous metal alloys or permalloy. And the magnetic metal thin film having substantially uniform columnar grain structure or uniform magnetic anisotropy, over entire area of the film.

A magnetic thin film consisting essentially of Fe, Al and Si and further containing nitrogen has high magnetic permeability and high hardness without lowering the magnetic properties such as saturation magnetic flux density or coercive force.The magnetic thin film has an increased specific resistivity and a lowered eddy current loss in the high frequency region and is suitable for a core material of magnetic transducer heads used in a high frequency region.The magnetic thin film is prepared by, for example, physical vapor deposition or ion implantation.
摘要:
A filtering apparatus is used to continuously separate a large quantity of a substance such as a slurry, sludge or other suspension into a liquid component and a solid component in such a manner that the separated solid component is obtained as a cake in a semi-dried condition, and comprises a rotary drum including a perforated cylindrical member and a filter cloth provided on the outer peripheral surface. The drum is supported for rotation so that a portion thereof is immersed into the substance to be filtered. The pressure within the drum is reduced by a vacuum pump so that the liquid component of the substance is drawn into the drum through the portion thereof is immersed into the substance while the solid component of the substance is accumulated on the filter cloth of the rotating drum and is held as a cake thereon. The cake is continuously removed by a doctor blade in the portion of the drum which is exposed to the atmosphere.
摘要:
Each of a pair of magnetic core halves includes a substrate and a thin magnetic metal film formed on the substrate. The substrate is notched with a winding groove. The pair of the magnetic core halves are integrally bonded to each other so that a gap filling film is formed between the facing surfaces of the thin magnetic metal films. The zero depth position of the magnetic gap which is determined by the length of the facing thin magnetic metal films is offset to a magnetic recording medium sliding surface of the magnetic head from the notching start position of the winding groove on the side of the magnetic gap. Hence, the shape of the thin magnetic metal film exposed on the magnetic recording medium sliding surface is maintained constant from the initial position to the depth zero position.
