Title: Liquid crystal display device
Inventor: HAIJI JOHAN
IPC: G02F1/13363
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To improve the performance of the angle of visibility of a liquid crystal display device by providing a liquid crystal cell and a compensation layer having structure where its optical axis is inclined and twisted for the purpose of compensation and changing the inclined and twisted structure for the purpose of the compensation in the thickness as the compensation layer. SOLUTION: An LCD 200 is provided with the compensation layer 220 and the LC cell 230. The layer 220 has five layers L1' to L5', the optical axes of the layers L1 ' to L5' imitate the layers L1 to L5 of the LC cell 230. The layer L1' compensates the layer L1. The layers L2' and L3' compensate the layers L2 and L3, respectively, then the layers L4' and L5' compensate similarly. The layer 220 has negative double refraction (ne <no ) and the absolute value of >=n' is equal to the absolute value of Δn. The layer 220 has the negative double refraction and is twisted rightward though the cell 230 is twisted leftward. Therefore, the dependency of the angle of visibility of the characteristic of the LCD is compensated and the angle of visibility is made wider without sacrificing display efficiency.

Abstract: PURPOSE:To convert a stable optical spot by correcting a change in the astigmatic difference of a laser light source by the chromatic abberation of a collimeter lens. CONSTITUTION:Beams projected from a semiconductor laser 1 are condensed by a collimeter lens 21, made parallel beams and then converged onto the recording face of a disk 9 through a shaping prism 4, a deflecting beam splitter 6, a 1/4 wavelength plate 7, and an objective lens 22 to form an optical spot 10.

Title: Magnetic disk data protection system

Abstract: PURPOSE:To prevent the format of a data part in a magnetic disk from being broken by controlling a read gate signal at the time of disconnecting a power supply so that a read clock signal sent from a VFO to a disk control is not synchronized with a read data signal. CONSTITUTION:When the power supply is turned off at a point A on the way of a data part of a sector 1, a power supply OFF signal is turned on and an input to an AND gate 12 is turned to '0', so that the AND gate 12 is turned off. Thereby, a read gate signal (RG) to be sent to a variable frequency oscillator (VFO) 13 is not outputted from a point (a). Even if the RG is outputted from a disk control 34 at a point B, the RG is not inputted to an RG terminal of an IC in the VFO 13 and is outputted to the disk control 34. A read clock signal (RCLK) is not synchronized with a read data signal (RDATA). Consequently, data in a magnetic disk 35 can be prevented from being broken.
