Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a glass substrate, by which the occurrence of defects on the surface of the glass substrate can be suppressed, and residual particles of a polishing agent after polishing can be efficiently removed while keeping the quality high.  <P>SOLUTION: The glass substrate is manufactured by polishing a glass base material with a polishing agent containing particles of cerium oxide and then cleaning the polished glass base material by using a cleaning chemical solution containing three components of an acid, a reductant, and fluorine ions.

Filed: 2003-05-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a recording medium utilizing a magnetooptical effect capable of displaying a high-contrast image, and a polarizer which has a large area, is applicable to a display device and has a high transmittance of light without coloring.  <P>SOLUTION: The display comprises the recording medium 9 provided with a micro magnetic head array 11. The recording medium 9 is formed by laminating a polarizer layer 3, a transparent magnetic layer 5, and a reflection layer 7 in order. The reflected light is made so as not to pass again through the polarizer layer by magnetizing the transparent magnetic layer 5 by the micro magnetic head array 11, and causing the plane of polarization of the polarized light to rotate by the magnetooptical effect in the magnetized part. On the other hand, since the reflected light repasses through the polarizer layer 3 in the non-magnetized part, a contrast appears between the magnetized part and the non-magnetized part. Moreover, the polarizer layer 3 and the transparent magnetic layer 5 are formed with thin films arrayed vertically on a substrate, and thereby a high polarization effect and a high magnetooptical effect can be obtained, so that a high-contrast image can be displayed.  <P>COPYRIGHT: (C)2004,JPO
