Abstract: PROBLEM TO BE SOLVED: To make background color white in a color liquid crystal display device using birefringence effect by adding a dichroic dyestuff into a liquid crystal to allow the resulting liquid crystal layer to absorb light of specified wavelength and changing the absorption with the change in voltage value to be applied to the device. SOLUTION: In this display device, the product (Δn.d) of the refractive index anisotropy (birefringence, Δn) of a nematic liquid crystal 15 and the thickness (d) of a layer of the nematic liquid crystal 15 is adjusted to >=0.12μm and also, a dichroic dyestuff 17 is added to the nematic liquid crystal 15 in a 0.5 to 5wt.% ratio to the liquid crystal 15 to allow the resulting liquid crystal layer to absorb light of specified wavelength and to change the absorption by changing the voltage value to be applied to the device.  At this time, the angle (made with the normal to the liquid crystal layer) of the major-axial direction of each of molecules of the dichronic dyestuff 17 added into the nematic liquid crystal 15, together with that of each of molecules of the liquid crystal 15, is changed with the change in voltage value applied to between electrode layers 12a and 12c and when the voltage is not applied, the absorption of light of specified wavelength by the liquid crystal layer becomes maximum and with the increase in applied voltage, the absorption is lowered. Thus, when the voltage is not applied, background color of the display can be made white.

Title: Device for and method of detecting position of movable body driven by dc motor
Inventor: INAGE KATSUYUKI
IPC: B60J1/00
Filed: 1992-12-02
Abstract: PURPOSE:To detect the position of a moving body, for example, a pane of a car with high accuracy. CONSTITUTION:A drop voltage Vi induced by a motor current flowing in a DC motor (M) which drives a pane (WG) enters a narrow-band/pass/filter(BFP) 21. The motor current includes motor rotary speed and a pulsating component of a frequency in proportion to the number of motor poles. The DPF 21 detects this pulsating component with high accuracy where a pulse detection circuit 22 converts the detected component into a series of pulse trains.
