    摘要: A heat-resistant resin composition comprised of a mixture prepared by kneading a polybutylene terephthalate resin together with a component different from said polybutylene terephthalate resin, wherein a β relaxation peak of said heat-resistant resin composition on the tan δ curve determined by the dynamic viscoelasticity measurement defined in Japanese Industrial Standard K 7244-4 appears at a temperature lower than a temperature at which a β relaxation peak of a composition composed singly of a polybutylene terephthalate appears; and said another component is dispersed in said polybutylene terephthalate resin phase in a form of particles having sizes of 1 μm or smaller.

    摘要: Locking claw engages a recording medium to be transferred, and a determination is made as to which of a plurality of predetermined points a current position of the locking member corresponds to. Current position of the recording medium can be determined indirectly on the basis of the thus-determined predetermined point corresponding to the current position of the locking member. If any recording medium is not properly settled in a predetermined rest position at power-ON, then the recording medium is automatically transferred to be settled in the predetermined rest position. Simplified detection of the position of the locking claw is made in absolute or quasi-absolute form, by a picker position detector unit that is provided in association with a rotating drive shaft of the locking member and employs a simply-constructed mechanism capable of generating detection pulses responsive to predetermined rotational angles of two shafts rotating at different rates. Each of the plurality of predetermined points defined for the locking claw can be identified in absolute or quasi-absolute form on the basis of a combination of patterns of the thus-generated pulses. Thus, in feed transfer of a recording medium, such as a DVD medium, the position of the medium can be detected in a simplified manner and can be automatically controlled to be properly settled in the predetermined position upon power-ON.

    摘要: An ingot is made from a used target of 30 weight % or more, and new metals of the same components, and recycled alloy powder is made by a gas atomizing process. Magnetic permeability is controlled not to exceed 2 by adjusting the content of rare earth metals in rare earth alloy powder to be at least 35 weight %. By blending the recycled alloy powder with other powder to produce alloy powder containing at least 50 weight % of rare earth alloy powder having a magnetic permeability not higher than 2 and containing at least 65 weight % of rare earth alloy powder. By sintering the alloy powder under pressure and thereafter cutting top, bottom and side surfaces of the sintered material, a target having a magnetic permeability not higher than 2 and having a thickness not less than 8 mm is fabricated.

    摘要: A head chip of a magnetic head is produced by a method in which magnetic core half blocks, each having plural track width delimiting grooves on its major surface and having a magnetic metal film of a soft magnetic metal material formed on the major surface, are abutted to each other with a gap material in-between to form a magnetic head block which is then sliced to give plural head chips for the magnetic head. Each track width delimiting groove is polygonally-shaped in cross-section and has at least two bends. This enables suppression of cracks of exfoliation of the magnetic metal film otherwise caused in the magnetic core during its fabrication to improve product yield and operational reliability.
