CONSTITUTION:One picture element (shutter) part of the liquid crystal (shutter array) consists of the shutter opening part and an FET forming part adjoining to it. An FET consisting of a semiconductor layer 2, source electrode 3, drain electrode 4, gate electrode 6, and protection film is formed on one substrate 1a and this is covered with the liquid crystal oriented film 9a. A transparent electrode 8a connected to the drain electrode 4 is formed on the substrate 1a of the shutter opening part and this is covered with an liquid crystal oriented film 9a. A transparent electrode 8b is formed on the other substrate 1b at the opening part and the oriented film 9b is formed over the entire surface. When an electric field is applied to liquid crystal 10, the shutter is closed. The thickness of the oriented films 9a and 9b is set to <=5,000Angstrom  to secure a voltage applied to the liquid crystal and maintain excellent contrast.

Title: Head feed mechanism for magnetic disk drive
Inventor: SAGAWA MASAAKI
IPC: G11B21/02
Filed: 1987-04-08
Abstract: PURPOSE:To securely prevent a side slip of a screw pin by simple constitution without sacrificing the movability of a magnetic head by abutting a screw pressing spring against a groove bottom section of the thread of a screw gear. CONSTITUTION:The screw pressing spring 120 is disposed in an opposite position to a screw pin 118 to hold the screw gear 116 between them, abutting on the groove bottom section of the thread of the screw gear 116, so that the slippage of the screw pin 118 in the radial direction of the screw gear hardly arises. Moreover, since the pressing spring 120 is positioned to the groove bottom section of the screw gear 116, the screw pressing spring 120 itself is regulated its slippage in the axial direction of the screw gear 116, so that the side slippage of the screw pin 118 also very hardly arises. By this method, the appropriate intermeshing condition of the screw pin 118 with the screw gear 116 can well be kept out without strengthening an elastic force of the screw pressing spring 120.
