    摘要: Embodiments of the invention reduce disk fluttering while ensuring good assemblability in a magnetic disk apparatus. A magnetic disk apparatus comprises a recording disk that is an information medium configured by one or plural disks; a motor causing the recording disk to rotate; a carriage supporting a head that records information to, or plays back information from, the recording disk; a casing housing the recording disk; and a shroud disposed surrounding an outer periphery of the recording disk. A groove that extends along the recording disk is formed, vertically asymmetrical with respect to an outer peripheral surface of the recording disk, in the shroud surface at a position where a corner portion formed by the outer peripheral surface and a top surface or bottom surface of the recording disk extends in a radial direction.

    摘要: In a multilayer ceramic circuit board comprising a substrate, an insulating layer on the substrate, and a conductive pattern on the insulating layer, an additive of Cr.sub.2 O.sub.3 or MnO.sub.2 is added to the insulating layer to reinforce adhesion between the insulating layer and the conductive pattern. Each of the substrate and the insulating layer is manufactured by firing at a temperature between 800.degree. C. and 1000.degree. C., alumina particles and a glass composition comprising an alumina component. When a total amount of alumina in the substrate is equal to or greater than that in the insulating layer, an amount of Cr.sub.2 O.sub.3 or MnO.sub.2 is restricted to a range between 0.1% and 10.0% by weight, with a difference between the total amounts of alumina falling within a range between 0% and 30% by weight. When the total amount of alumina in the substrate is smaller than that in the insulating layer, the amounts of Cr.sub.2 O.sub.3 and MnO.sub.2 may be between 0.1% and 10.0% by weight and between 0.1% and 15% by weight, respectively. The difference between the total amounts of alumina may be between 0% and 20% by weight.

    摘要: A variable geometry turbocharger in which a bill-like projection portion is arranged in a part of an outer periphery of a flow passage spacer, and the projection portion is protruded to a turbine rotor side at a predetermined angle or the projection portion is movably provided. Alternatively, a rod-like member is arranged in a part of an outer periphery of a flow passage spacer and the rod-like member is arranged so as to be adjacent to the turbine rotor side at a predetermined angle. Alternatively, a guide vane in which a leading edge side of a rotational shaft is eliminated is arranged in a part of an outer periphery of a flow passage spacer and the rotational shaft is arranged so as to be adjacent to the turbine rotor side at a predetermined angle. Further, a heat resisting cast steel having a little amount of carbon is employed as a material for a casing and a guide vane table sectioning the turbine chamber, and without using the flow passage spacer and in place of the flow passage spacer, both side walls sectioning the turbine chamber themselves keep a gap with respect to the guide vane minimum. Accordingly, a high turbine efficiency can be obtained by preventing a gas stream from being separated at the back of a flow passage spacer and inside a guide vane, since a hydraulic energy loss is reduced and a uniform and high average flow speed distribution is realized at a position of an inlet of a turbine rotor.
