Title: Antiferroelectric liquid crystal display element
Inventor: TANAKA TOMIO
IPC: G02F1/141
Filed: 1995-05-31
Abstract: PURPOSE: To allow an antiferroelectric liquid crystal display element of an active matrix type to distinct gradation display. CONSTITUTION: Antiferroelectric liquid crystals 21 constituting of liquid crystal molecules which have first and second ferroelectric phases and antiferroelectric phase varying in the arranging states of the liquid crystal molecules from each other and rotating around the molecule major axis are sealed into the liquid crystal display element of the active matrix type in the state that the double spiral structures drawn by the liquid crystal molecules of the smectic CA* phase dissipate. The rotation of the liquid crystal molecules is suppressed and the liquid crystal molecules incline in the direction perpendicular to the impressed electric field when voltage is impressed on the antiferroelectric liquid crystals 21.  Since the inclination of the liquid crystal molecules corresponds to the impressed voltage, the directors of the antiferroelectric liquid crystals 21 change continuously according to the impressed voltage and form the numerous optical intermediate states. In addition, hysteresis is small. Then, the distinct gradation display is made possible by driving such liquid crystal display element.

Title: Optical switch
Inventor: NISHIMOTO YUTAKA
IPC: G02B6/12
Filed: 1988-06-24
Abstract: PURPOSE:To obtain an optical switch which simultaneously satisfies low driving voltage and low loss by projecting the surface area of a 1st substrate and making the projected part at least 0.1mum higher than the surfaces of two optical wave guides. CONSTITUTION:The title switch is constituted by using a directional coupler and has such a structure that only an area which forms an electrode between two nearby optical wave guides makes an LiNbO3 projecting part. When the waveguide light is shifted from an optical wave guide 4a to an optical wave guide 4b, or when the waveguide light is shifted from the optical wave guide 4b to the optical wave guide 4a, the waveguide light passes under an electrode 6a formed between the optical wave guides 4a and 4b. Since the electrode 6a is formed on the LiNbO3 projecting part 3, the LiNbO3 projecting part 3 forms a buffer layer. And the projecting part is made at least 0.1mum higher than the surfaces of both optical wave guides 4a and 4b. Thus, the optical switch where the driving voltage is low and the loss is small can be obtained.

Abstract: PURPOSE: To improve the starting characteristics of an engine (particularly at the time of low temperature) by stopping a charging current to a battery by an alternator until the complete explosion of the engine is detected, and gradually increasing a conducting amount after the explosion is detected. CONSTITUTION: A transistor 23 is driven at a low duty during cranking, an alternator 1 is stopped to generate (internal generation without supplying a charging current to a battery), and the output 257 of a complete explosion detector 25 is 'Lo'. When the engine is completely exploded and the number of revolutions of the engine is abruptly increased, the output 257 of the detector 25 becomes 'Hi', the explosion is detected, and the output 263 of a switching circuit 26 is fixed to 'Lo'. Thus, the duty of the transistor 23 is raised, and the alternator 1 starts generating. Thus, the duty of the transistor 23 is gradually increased, and the output current of the alternator 1 is increased corresponding to the increase in the duty. In this manner, the number of revolutions of the engine smoothly increases.

Abstract: PROBLEM TO BE SOLVED: To detect uneven defects of various sizes and forms including small linear unevenness by forming a twodimensional statistical data by texture analysis to an image data subjected to hierarchical processing. SOLUTION: In a hierarchical processing part 4, area division is performed with an original image data 2 as micro hierarchy of the lowest level, areas are hierarchically integrated to form macro areas and hierarchies. n-Pieces of hierarchies are formed according to the number of picture elements of a display to be inspected, and the larger the number of picture elements of the data 2 is, the more the number of hierarchies (n) is increased.
