Title: Liquid crystal panel and production thereof and liquid crystal projection type television
Inventor: TAKAHARA HIROSHI
IPC: G02F1/1335
Filed: 1991-09-27
Abstract: PURPOSE:To attain the higher brightness of a display screen and the image display of a high contrast without using polarizing plates for a liquid crystal panel. CONSTITUTION:A diffraction grating 15 is formed by using the material of a high-polymer dispersed liquid crystal 18. This diffraction grating 15, etc., are formed by applying a resin contg. the liquid crystal on a counter electrode substrate 17 and bringing a mold plate into tight contact therewith, then impressing a magnetic field thereto to orient and fix the liquid crystal. The refractive index of the diffraction grating 15 is set equal to the ordinary light refractive index of the high-polymer dispersed liquid crystal 18. A difference in the refractive index arises between the liquid crystal 18 and the diffraction grating 15 when a voltage is not impressed to the liquid crystal 18. The incident light on the liquid crystal 18 is then diffracted and scattered by the liquid crystal 18. The rectilinear light is, therefore, extremely diminished. There is no difference in the refractive index any more between the liquid crystal 18 and the diffraction grating 15 and the incident light advances rectilinearly when the voltage is not impressed to the liquid crystal 18.

Inventor: TAKAHIRA ASHITO
IPC: B08B3/02
Filed: 1987-10-02
Abstract: PURPOSE: To improve washing efficiency by providing a driving chamber disposed substantially independently from a washing chamber with a transmission mechanism. CONSTITUTION: When an arm A arrives at a lower limit position, a motor automatically rotates revere. This arm A is moved upward. When the arm A arrives at an upper limit position, the motor automatically rotates backward and the arm A is moved downward. This act is repetitively executed for the previously assigned washing time. While the washing treatment is executed, an exhaust valve EV is opened and, therefore, the refuse generated from the driving mechanism of the driving chamber MU is discharged via a discharge port through the exhaust valve EV. When the assigned washing time elapses, the injection of water or pure water or the like by washing nozzles N1 and N2 is stopped and a drain valve DV is closed. As a result, the washing efficiency is enhanced.
