Abstract: A magnetic semiconductor material having magnetization characteristics and a method for preparing the same is provided. In the method for preparing the magnetic semiconductor, Mn is vapor-deposited at a thickness of 200 to 300 ? onto a CdGeP2 single crystal (2) while the CdGeP2 single crystal (2) is maintained at a temperature of about 390° C. in a molecular beam epitaxy apparatus (1). The Mn-deposited CdGeP2 single crystal is heated at a temperature of about 510° C. for 1 hour. Thus, a magnetic semiconductor comprising CdMnGeP2 and having magnetization characteristics at room temperature is prepared.

Abstract: A disc recording and/or reproducing device includes a disc compartment that has a plurality of disc mounts placed one upon another, on which discs are mounted. The device also includes a recording and/or reproducing mechanism for selectively recording and/or reproducing a disc mounted on one of the plurality of disc mounts. An injection mechanism is included for ejecting the disc mounted on the disc mount. A control mechanism is included that moves along a line substantially perpendicular to the placing direction and is configured to start the recording and/or reproducing mechanism when in a first position and start the ejection mechanism when reaching a second position on another side of the line.

Abstract: A pair of pins 2c, 2d is arranged on the left and right of each of a plurality of trays 2 placed vertically movably so as to protrude laterally, whereas separating cams 82 are arranged on both sides of the trays 2 in a protrudable and withdrawable way. The separating cams 82 are formed with four first separating control parts 82c1 for moving upward the pins 2c, 2d of the selected tray 2 and the tray(s) 2 thereabove, four second separating control parts 82c2 for moving upward only the pins 2c, 2d of the tray(s) 2 above the selected tray 2, and four third separating control parts 82d each for engaging with only a pair of pins 2c, 2d of the selected tray 2. Movement of the separating cam 82 forms spaces above and below the selected tray 2 to hold a disc on the selected tray 2 from above and below for reproduction on the spot.

Abstract: In an on-vehicle disc player having a disc elevator (22) for making a plurality of trays (2) each having a CD placed on it stacked one over another in the vertical direction move in the stacking direction, there is provided plate springs (2e) for pressing an inserted CD at both sides of the tray (2). Further, there is provided separating cams (82) for forming spaces at both side of the tray (2) having a CD to be reproduced, by the movement in the fore-and-aft direction. Holding means for holding and rotating the CD are inserted to the spaces formed by the separating cams (82) to hold the CD. Thereafter, by pushing down the plate springs (2e) which has pushed and caught the CD in the tray (2) by means of peripheral portions (82x) of lower faces of upper stage entering portions (82j) of the separating cams (82), the CD is released and the tray (2) is pushed down to be separated from the CD.

Abstract: In place of a conventional tray, a pair of mounting stages 2 is arranged as a disc holding device, wherein six pairs of mounting stages 2 are vertically movably placed one upon another by arranging guide supports 23 through guide holes 2i of the pair of mounting stages 2 for mounting a disc thereon. Spring bearings 2j are arranged on the uppermost mounting stages 2, inside which received are the lower ends of coil springs 24 enclosing spring guides 26 arranged between a top plate and a bottom plate, achieving reduced size and weight of the disc holding device for mounting discs thereon.

Abstract: In an on-vehicle disc player having a disc elevator (22) for making a plurality of disc carrying devices each having a CD placed on it stacked one over another, for example, in the vertical direction move in the stacking direction and a holding device (14) for holding and rotationally driving a CD, the disc player is provided with an inner slider (139) which moves in a direction (plane direction of a disc) perpendicular to the direction of stacking the disc carrying devices and makes the disc elevator (22) and the holding device (14) move in the stacking direction, a separating cam (82) which separates the stacked disc carrying devices to form a specified space, and an outer slider (140) which is coupled to the separating cam (82) and moves in a plane direction of a disc is provided.

Abstract: Apparatus for pushing out a disc placed on a tray between a pair of rollers, in a stable state including a pair of pushing-out mechanisms actuated by a return spring each provided with a pair of fixed shafts. For turning the pushing-out mechanism a device, such as a lever, operates against a pressing force of the return spring, and the pushing-out mechanism is engaged with a separation cam for controlling the insertion and/or the discharge of the disc.

Abstract: A nonexplosive chemical composition for gently and noiselessly breaking a rock or concrete mass. The composition comprises a principal component which is prepared by calcining a starting mixture comprising 100 parts by weight of quick lime and 1-20 parts by weight of calcium fluoride. In rock or concrete breaking operations, this composition in the form of aqueous slurry is poured into drill-holes and left to spontaneously hydrate and set with development of expansion pressure. For adequate retardation of the hydration, preferably a second fluoride such as Na.sub.2 SiF.sub.6 which gives CaF.sub.2 by reaction with CaO at the calcination temperature is added to the starting mixture. As an alternatively preferable method for the same purpose, an amino acid compound and/or a lignosulfonate is used as a hydration retarding agent which is mixed with the calcined principal component. Various auxiliary agents may optionally be added to this composition.
