A disc case having a case main unit including an accommodation chamber for rotatably accommodating a disc having a signal recording surface on at least one side of the disc, support member access openings provided in the top and bottom walls of the accommodation chamber so that a chucking member can apply an external pressure to the disc, a head access opening formed in the top or bottom wall of the accommodation chamber and tangent to the side wall surface of the accommodation chamber so that a read/write head can read and/or record signals on the signal recording surface of the disc, and a concave portion formed in an area extending from the side wall surface at the head access opening to the front fringe portion of the case main unit and concave with respect to the top or bottom surface of the main unit of the case. The disc case also includes a shutter installed on the case main unit to cover the support member access openings, the head access opening and the concave portion when the shutter is closed. The shutter opens to expose the support member access openings and the head access opening by sliding in at least one direction from the covered position along the front fringe portion of the case main unit. A shielding portion provided on the case main unit shields all or a part of the passages communicating with the accommodation chamber even when the shutter is closed.

A disk cartridge of the present invention comprises a case body (101) having a disk-storage portion and an opening/closing cover (201) having a pair of disk holding members (202) that hold a disk (10) in its inplane direction. The accommodated disk (10) is loaded together with the opening/closing cover (201) into an adapter having compatibility with a large disk cartridge. Thus, information can be, for example, reproduced from the disk (10) in a drive unit designed for a large disk cartridge via the adapter. Moreover, a series of operations can be conducted without touching the disk directly.

A disc device accommodates a disc rotatably mounted therein, a plurality of first heads movable in a first direction radially of the disc, and a plurality of second heads movable in a second direction radially of the disc and perpendicular to the first direction. The disc has a first surface and a second surface opposite to each other, with an information area defined on at least one of the first and second surfaces. The information area is divided into an outer information region and an inner information region lying radially inwardly of the outer information region. The first heads are allowed to move within a limited distance across the outer information region so as to record or reproduce information on or from the outer information region, while the second heads are allowed to move within a limited distance across the inner information region so as to record or reproduce information on or from the inner information region.

This invention is of a Cr--Mo steel pipe of a wall thickness of 13 mm or less, containing C: 0.03-0.10 wt %, Si: 0.50-1.00 wt %, Mn: 0.30-0.60 wt %, P.ltoreq.0.007 wt %, S.ltoreq.0.020 wt %, Cr: 1.00-1.50 wt %, Mo: 0.45-0.65 wt %, Al: 0.002-0.010 wt % and N: 0.002-0.010 wt % and the remainder consisting of Fe and unavoidable impurities for which preheating and postheating treatments for the prevention of weld cracking and stress corrosion cracking can be effectively omitted, said steel pipe of this invention being suitable for steam piping applications such as STPA23 used in power generation plants, etc.
摘要:
The present invention provides a cartridge accommodating a disk therein which is inserted into a cartridge holder, the cartridge holder being provided with a mis-insertion protection member. The mis-insertion protection member is located within an insertion path along which the cartridge is inserted into the cartridge holder. The cartridge has a substantially rectangular shape. The cartridge has a corner portion at each of four corners of the substantially rectangular shape, the corner portion being shaped so as to abut on the mis-insertion protection member to move the mis-insertion protection member out of the insertion path. The cartridge has at least two mis-insertion protection mechanisms for engaging with the mis-insertion protection member so as to prevent the cartridge from being mis-inserted. The cartridge has two side surfaces which are substantially perpendicular to a surface of the disk and extend along a direction substantially parallel to a direction in which the cartridge is inserted into the cartridge holder. A mis-insertion protection mechanism of the at least two mis-insertion protection mechanisms is provided on each of the side surfaces.

A disk cartridge of the present invention comprises a case body having a disk-storage portion and an opening/closing cover having a pair of disk holding members that hold a disk in its inplane direction. A grip of the opening/closing cover engages with a grip-guide part of the case body. They may be formed asymmetrically with respect to the center line of the opening/closing cover in its insertion direction, thus preventing the opening/closing cover from being inserted into the case body upside down.

A disc cartridge includes a disc holder for supporting a recording medium. The disc holder includes a grip. A case defines a housing portion for receiving the disc holder and the recording medium. The case allows the disc holder with the recording medium to be inserted into and removed from the housing portion via an opening. The disk holder also includes a lock for securing the disc holder to the case at a position. The grip has side portions tapering from a bottom end to a top end of the grip, the top end of the grip having a smaller width than the bottom end of the grip. A cut of the upper case and a cut of the lower case are shaped to correspond with the taper of the side portions of the grip thereby facilitating smooth engagement of the grip and the cuts.
