IPC: G11B5/738
Filed: 1983-08-09
Abstract: PURPOSE:To obtain a magnetic disk device whose magnetic layer is never cracked by the temperature change and having fine surface roughness and high resolving power, by forming an anodized aluminium layer on the surface of an Al base material through the electrolysis carried out in an aqueous solution containing Cr<6+> and then forming a magnetic film on said anodized aluminum layer. CONSTITUTION:The surface of an Al disk 1 is finished to a mirror surface by means of a diamond lathe or a lapping machine and then subjected to electrolysis in an aqueous solution containing Cr<6+>. Thus an anodized aluminum layer 2 is formed on the disk 1. As shown by a typrical figure, the layer 2 is formed to have the structure which contains resin-shaped holes interlacing each other. As a result, the layer 2 is just shifted in the expanding directions of the interlaced holes when the disk 1 expands toward an arrow A at a high temperature. Thus no crack is produced on the surface of the disk 1. Therefore no crack is produced to a magnetic layer 3 when the layer 3 is coated on the layer 2 by a sputtering method or a lubricant film is formed on the layer 3. Thus the high resolution characteristics can be secured for a magnetic disk.

Title: Active matrix type liquid crystal display device
Inventor: HOSHIYA TAKAYUKI
IPC: G02F1/1362
Filed: 1987-06-10
Abstract: PURPOSE:To reduce line defect due to the short-circuit of a scanning line and to realize redundant constitution without increasing the number of switching devices, by constituting a device in such a way that the second output terminal of the switching device is connected to an adjacent image element electrode. CONSTITUTION:Constitution is formed in such a way that the second output terminal D of the switching device Tij is connected to the adjacent image element electrode Eij+1 in the same row. Also, since no switching devices Tij+1 and Tij+2 are connected directly to a common bus line or a scan bus line of next order, no short-circuit between the scanning line and the common line or two scanning lines is generated even when the short-circuit is generated. Consequently, it is possible to prevent the line defect from being generated. In such a way, it is possible to realize the redundant constitution without increasing the number of the switching devices, and to increase a numerical aperture by reducing the number of switching devices.
