Title: Revolving disk-shaped storage
Inventor: YAMAGUCHI YUZO
IPC: G11B21/21
Filed: 1988-01-27
Abstract: PURPOSE:To prevent the damage of a disk and a slider and the activation impossibility of a storage by providing a contact area reducing means to reduce a contacting area between the relative operating surface and disk surface of a transducer loading means during the stop of a revolving disc. CONSTITUTION:Load adding means 10 and 11 are set in every two disk intervals to be composed of an adjacent disk 3 and set in a position ro where a bearing 12 does not contact to the disc 3. Then, just after the disc 3 is stopped, the bearing 12 is pushed to a radius rc position by a feed mechanism, which is composed of a motor 18, a feed screw 16 and a reference screw 17. A load is added to the disc 3 and the disc is deformed by the deforming power of a fork 14. Then, the contacting area between the disc 3 and a transducer loading means 6 is made smaller than the relative operating area. Thus, absorbing force to be generated when the transducer loading means 6 is still set on the disc is made weak and the occurrence of the trouble such as impossibility of activation of the device by receiving the damage in the disc 3 or transducer loading means 6 at an activating time or by the lack of motor capacity, is prevented from being generated.

Abstract: PURPOSE:To magnify and reduce smoothly binary picture information including oblique lies such as a character pattern by connecting 2-split points of each side of a rectangle taking 4 adjacent picture elements on an original picture as apexes with a straight line segment so as to divide the rectangle into 8 triangle areas. CONSTITUTION:A projection means 2 projects lattice having an interval being a reciprocal of a magnification onto an original picture, obtains the relation of correspondence between lattice points of the lattice projected onto the original picture and picture elements on the converted picture, and a division means 3 divides the rectangle into 8 triangle areas by tying two division points of each side of the rectangle taking 4 adjacent picture elements as apexes on the original picture projected with the lattice by the projection means 2 by means of line segments. An interpolation means 4 decides the lightness of the picture element on the converted picture corresponding to the lattice points included in the rectangle based on the lightness of the 4 picture elements being the apexes of the rectangle including the lattice points and on the areas including the lattice points. Thus, the connection of the picture elements on the converted picture in the oblique direction is made smooth.
