Abstract: An information processing apparatus that is capable of preventing lowering of operability when printing is performed. In a client terminal, an OS acquires capability information related to printing capability from a server that provides a cloud print service or a printer, and a controller displays a screen. The capability information has a hierarchical structure including at least one item name and a plurality of attribute values belonging to the item name. The controller can perform first display for collectively displaying the item name and the attribute values and second display for displaying the plurality of attribute values in a state sorted into groups of attribute values relevant to each other.

Abstract: A disk drive apparatus in which a hard disk is fitted on a disk-fitting outer peripheral portion of a rotor hub. A gap is defined on the outer periphery of the rotor hub such that the axial height of the gap decreases radially inward. An elastic ring member, which is appropriately tensed in the circumferential direction, fits in the gap so as to exert a contracting force which serves to clamp the hard disk between itself and a disk supporting surface. The hard disk can be securely and easily fixed to the rotor hub with uniform application of the clamping pressure over the entire circumference, even when the axial height of the whole disk drive apparatus is reduced.

Abstract: A method for production of a sliding member exhibiting excellent mechanical strength, resistance to thermal shock, and resistance to corrosion at elevated temperature is produced by a process of manufacture which comprises firing a shaped mass of silicon nitride powder obtained by the silica reduction method and cutting the resultant sintered ceramic mass in a prescribed shape by machining.

Abstract: A sliding-contact type ceramics article having a high density portion for increasing the mechanical strength of its slide-contact portion with an associated article. A method for manufacturing such a sliding-contact type ceramics article which is characterized in that, at first a compact body having a configuration which is approximate to a final article is molded in such a manner that a slide-contact portion with an associated article is intensively compressed, and then the compact body is grinded to obtain a compact body of a final configuration.
