Title: Method for orienting liquid crystal optical element
Inventor: YUASA KOYO
IPC: G02F1/141
Filed: 1990-11-15
Abstract: PURPOSE:To easily perform orientation processing with good productivity and to obtain high-contrast orientation by impressing/processing an electric field after performing the bending and deforming processing of a liquid crystal optical element so that ferroelectric liquid crystal may be oriented. CONSTITUTION:The oriented liquid crystal optical element is composed of the ferroelectric liquid crystal interposed and held between two flexible substrates where an electrode is disposed. The bending and deforming processing of the liquid crystal optical element is performed so that the ferroelectric liquid crystal may be oriented. For example, an element already oriented 3 is obtained by performing the bending and deforming processing of an unoriented element 1 obtained by using an orientation device consisting of three-roll group 2. Thereafter, voltage which becomes electric field whose maximum amplitude is >=5MV/m is impressed between the electrodes of the liquid crystal optical elements so that the smectic layer structure of the ferroelectric liquid crystal may be changed. Thus, the element is easily oriented with good productivity, and the high-contrast orientation with few zigzag defect is obtained.

IPC: G11C16/06
Filed: 1987-12-04
Abstract: PURPOSE:To suppress energy consumption by detecting the size of the output voltage of a high pressure generating means and changing a voltage rising rate according to the size. CONSTITUTION:When a control signal CNT1 is outputted to instruct a writing from a CPU4 and a high voltage VPP for writing does not achieve a prescribed value for a control signal CNT4 of a comparator 14, a control signal CNT2 is outputted and an oscillating means 1 starts oscillation. A booster means 6 receives the output of the oscillating means 1 and boosts an external power source voltage VCC and the boosted voltage VPP is detected by a voltage detecting means 12 in a constant voltage means 10. When a reference voltage VR1 to be outputted from the voltage detecting means 12 goes to be larger than a reference voltage VR2, the output of the CNT2 is prohibited by an output CNT4 of the comparator 14 and the oscillation of the oscillating means 1 is stopped. Then, the maximum value of the voltage VPP is limited and a constant voltage is obtained. Thus, the energy consumption can be suppressed.

Abstract: PURPOSE:To easily obtain the focus position without using complicate equation by supposing a plane vertical to the camera optical axis in a space and detecting the min. error position by a means for projecting the reference points of at least three points, on the plane. CONSTITUTION:The camera focus position is set at FC, and the three dimensional coordinate values are represented by Fx, Fy, and Fz, and the vertical plane P relative to the camera optical axis is set.
