Title: Liquid crystal display element
Inventor: YAMAMOTO TAKESHI
IPC: G02F1/1339
Filed: 1990-11-27
Abstract: PURPOSE:To keep high contrast and to prevent the occurrence of vacuum foams at the time of keeping an element at a low temperature by making the spacer of a liquid crystal cell for interposing a liquid crystal component and a spacer for controlling a substrate distance between the substrates hold optical characteristics and thermal expansion coefficient equivalent to those of the liquid crystal component. CONSTITUTION:The liquid crystal component 13 and the spacer 14 which is constituted of high polymer liquid crystal component respectively provided with the optical characteristic and the thermal expansion coefficient equivalent to those of the liquid crystal component 13 are interposed between the substrates 10 and 10'. Then, when a voltage is not impressed, a double refraction effect is given to light transmitted through the spacer 14 as well as the light transmitted through the liquid crystal component 13, meanwhile, when the voltage is impressed, the optical characteristics of the spacer 14 is different from that of the liquid crystal component 13, so that the transmittivity is not changed in comparison with the case of using the usual spacer. Meanwhile, in the case that a spacer density is made dense in order to keep the thickness of the liquid crystal cell constant, volume reduction rate caused on the lowering of the temperature of the spacer is close to the volume reduction rate of the liquid crystal component, so that the vacuum foams are hardly generated. Thus, the liquid crystal display element having high display definition and high contrast without generating the vacuum foams at the time of keeping at a low temperature can be obtained.

Filed: 1988-12-22
Abstract: PURPOSE:To determine the period in a short time by detecting peak points of a specific number of signals, deciding a waveform according to the large- small relation between the mutual difference between positive-side peak points and the mutual difference between negative-side peak points and finding the period from the decision result. CONSTITUTION:Eight peak points P2-P9 are inputted from the point of time when a signal is inputted. The positive maximum value and negative maximum value which are obtained so far are stored as peak points every time the signal passes one of zero point Z1-Z9. Thus, the peak points which have the maximum value and minimum value between zero-cross points of the signal are securely found. Then the condition that the differences between mutually the adjacent positive peak points P3, P5 and P7 and negative peak points P2, P4 and P6 are equal to or smaller than a specific value and two sums of two adjacent sections of sections T2-T9 which are delimited by the zero points are found and when the conditions that the differences are equal to or smaller than the specific value is satisfied, a waveform consisting principally of a fundamental wave is decided. Then the sums of two adjacent sections which are sectioned by the zero points is determined as the period.

Filed: 1989-12-14
Abstract: PURPOSE:To effectively prevent the characteristic variation of a laser caused by returning light by arranging an optical element which senses spatial coherence between the laser and an optical surface where the returning light of an external optical system is caused. CONSTITUTION:A random phase shifter 5 is arranged as the optical element which senses the spatial coherence between the semiconductor laser 1 and a lens 3 for condensing laser light 2.

As to the thickness of the film, it is the thickest in a black part, next thickest in an oblique cross stripes part, then in a sprinkled part and in a white part in order. Since the thickness of the dielectric film is different at random, the phase of the returning light is delayed at random and the spatial coherence is lowered, thereby preventing the characteristic variation of the laser 1 caused by the returning light.
