Abstract: PURPOSE:To obtain a liquid crystal display device having sufficiently high lightness and causing no coloration in background color by regulating a product of refractive index anisotropy multiplied by a thickness of a liquid crystal layer to 0.6-0.7, and regulating also an angle between orientation axes (angle of torsion of the liquid crystal layer) to 210-260 deg.. CONSTITUTION:Orientation films 6, 7 which have been subjected to rubbing, are pasted to each glass substrate 1, 2 so as to cover transparent electrodes 4, 5, and a liquid crystal material 8 is sealed between the glass substrates 1, 2. A polarizing plate 10 having high degree of polarization and a polarizing plate 11 having high transmittance are provided to the outside surface of the glass substrates 1, 2, respectively. Supertwisted nematic liquid crystal having a product of a thickness multiplied by the refractive index anisotropy arranged to 0.6-0.7 and 210-260 deg. angle of torsion between orientation axes of orientation films 6, 7, namely an angle of torsion of liquid crystal layers 8, is adopted as the liquid crystal material 8. By this constitution, sufficiently high lightness necessary for display is obtd. The polarizing plate 10 having high degree of polarization serves to make lighting color darker, and the polarizing plate 11 having high transmittance serves to make the background color whiter.

Filed: 1986-03-25
Abstract: PURPOSE:To make it possible to detect the wavelength of monochromatic light simply with good accuracy, by respectively alternately placing a first filter and a second filter on the light path between a spectroscopic machine and a light receiver for a spectrophotometry. CONSTITUTION:At first, a first filter 11 is placed on the light path between a spectroscopic machine and a light receiver 10 for spectrophotometry and output value (a) from the light receiver 10 for spectral photometry at this time is measured. Next, the first filter 11 is removed from the light path to place a second filter 12, which has spectral transmittance different in the ratio from that of the first filter 11 for each wavelength within a range desired to detect a wavelength, on the light path and the output value (b) from the light receiver 10 for spectrophotometry is measured. Next, the ratio a/b of measured values is calculated. On the basis of functional relation at this time, a wavelength can be detected from the ratio a/b. By this method, by reading the output value from the light receiver for spectrophotometry while wavelength feed is performed by the spectroscopic machine 9, the wavelength of monochromatic light can be detecting simply with good accuracy.

Abstract: PURPOSE: To obtain the stable pressure detector with simple constitution by using a composite piezoelectric element to which constant frequency signal is applied and so constituting the same that the analog output corresponding to the pressure received is fetched.  
     CONSTITUTION: A composite piezoelectric element 16 is constituted by mechanically joining the 1st and 2nd piezoelectric element 1, 2 to each other by way of a medium 5 such as metal. When the signal of a constant frequency signal source 3 is applied to the composite piezoelectric element 16, the signal voltage VPO of the constant amplitude portion of the constant frequency signal is obtained across the output terminals 7, 7' of the 2nd piezoelectric element 2. When a pressure P is applied to the pressure receiving face of the 2nd piezoelectric element 2, the output signal VP receives the amplitude modulation of which the amplitude changes to VPOWVPR, thence it is detected, whereby the pressure-sensitive detection output VD is obtained in the 1st load 9. Here, if the driving constant frequency voltage is fetched to the 2nd load 13 through the 2nd detecting circuit 12 and is applied together with the output of the 1st load 9 to a differential amplifier 14, the analog signal corresponding to the receiving pressure may be obtained.
