Abstract: PROBLEM TO BE SOLVED: To avoid a polarized state of light or coloring of transmitted light by forming a light-scattering layer on one or both surfaces of a transparent base body which gives a specified phase difference by the double refraction of transmitted light in the perpendicular or oblique directions. SOLUTION: A light-scattering layer 2 is formed on one or both surfaces of a transparent base body 1 which gives <=30 nm phase difference by the double refraction of transmitted light in the perpendicular and 40 deg. oblique direction. As for the transparent base body 1, a transparent material which gives a uniform phase difference is preferable, and a plastics film or the like is used. For example, transparent plastics such as cellulose, carbonate, acryl, vinylalcohol, amide, imide, styrene, allylate, ester, sulfone, ethersulfone, epoxy, vinyl chloride and olefin plastics can be used. As for the light-scattering layer, a resin layer having dispersion of transparent particles with different refractive indices or a layer having a finely roughened surface or having raises can be used.

Title: Optical shutter
Inventor: TSUKADA MASASHI
IPC: G02F1/01
Filed: 1991-02-20
Abstract: PURPOSE:To decrease the number of stages required for formation by driving the optical shutter with a low driving voltage and simplifying its structure. CONSTITUTION:A tensile stress is acted on a transparent film 30 by the operation of an electrically driven actuator 40 and the plane of polarization of light 20 transmitted through a transparent film 30 rotates according to the size of this stress. The transmission light quantity of the light 20 transmitted successively through a polarizer 12, the transparent film 30 and an analyzer 14 changes according to the magnitude of the tensile stress acting on the transparent film 30. Since the transmission light quantity of the light 20 is changed by the operation of the electrically driven actuator 40, the transmission light quantity of the light 20 can be changed by the lower driving voltage (for example, several volts) than with the optical shutter formed by utilizing an electrooptical effect (for example, the driving voltage is as high as several tens to hundred and some tens volts). In addition, the structure is made simpler than the optical shutter formed by utilizing a liquid crystal and the number of the stages is decreased.

Title: Magnetic sensor
Inventor: NAMIKI MASAYUKI
IPC: H01L43/06
Filed: 1986-03-07
Abstract: PURPOSE:To reduce a detection error by adding Hall voltages generated at output terminals of plural Hall elements formed on one semiconductor ship and arranging plural Hall elements in the positions where those are crossing at right angle mutually. CONSTITUTION:A piezoelectric resistance effect of a semiconductor chip 0 or an applied stress itself has anisotropic property. When a Hall element 1 and a Hall element 2 are arranged orthogonally, said anisotropic property functions so that an offset voltage of the Hall element 1 (V02-V01) and an offset voltage of the Hall element 2 (V04-V03) become roughly the same in their absolute values, but opposite in their polarities in most cases. Accordingly, the both offset voltages are added by a function of a comparator 3 etc. and are cancelled or set off. As a result, the offset voltage of the whole magnetic sensor, that is, the difference in potential at a time of no magnetic field between the Hall outputs H1 and H4 becomes small. Then, a detection error can be reduced.
