Title: Polarizing, separating and synthesizing device
Inventor: KIYONO MINORU
IPC: G02F1/03
Filed: 1980-10-02
Abstract: PURPOSE:To obtain an inexpensive, high-performance polarizing, separating and synthesizing dvice by forming and cementing polarizing filters on the flanks of a couple of symmetric electrooptic crystals, by mirror-finishing two flanks facing to  the cemented surface, and by providing electrodes on both upper and lower surfaces. CONSTITUTION:On one flank 2 of an electrooptic crystal 1 of lithium niobate, a polarizing filter layer made of a dielectric multilayered film is formed. This crystal 1 is cemented to another cyrstal having the same structure to from a hexagonal body. On a flank 3, a mirror surface of a dielectric single-layered or multilayered film is provided and electrodes 7 are provided on upper and lower surfaces perpendicular to the mirror surface. Incident light enters the crystal 1 from an incidence surface 4; S-polarized light is reflected by a polarizing filter surface 2, and P-polarized light is transmitted. The separated S wave and P wave are reflected by the flank 3 and synthesized through the polarizing filter surface 2 to be emitted from a surface 5. While a voltage is applied to the electrodes 7, the S- and P-polarized waves are converted mutually and the resulting synthesized light is emitted from a surface 6. Consequently, an inexpensive, high-performance polarizing, separating and synthesizing device is obtained.

Title: Polarizing light transmission plate and polarization plane light source
Inventor: MIYATAKE MINORU
IPC: G02B6/00
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To develop a light transmission plate from which exiting light of linearly polarized light can be obtd. while the polarizing direction (oscillation plane) of light can be controlled as desired. SOLUTION: This polarizing light transmission plate consists of a laminated body 4, a mirror reflection layer 5 on one surface of the body 4, and at least one light-diffusing layer 6 having maintaining property for polarized light on the other surface of the body 4. The laminated body 4 is produced by forming a scattering plate 3 for polarized light which has birefringent microregions dispersed and which has scattering anisotropy according to the polarization direction on one or both surfaces of a light transmitting resin plate 1. The polarization plane light source consists of the aforementioned polarizing light transmission plate and a light source 7 disposed in at least one side of the light transmission plate.  By this constitution, natural light can be used to enter the side face of the transmission plate to efficiently exit as linearly polarized light from one of the front and back faces without requiring formation of a special light-exiting means such as reflective dots on the light transmitting resin plate. The oscillation direction of the linearly polarized light can be controlled as desired by controlling the optical axis of the scattering plate for polarized light, and thereby, a liquid crystal display device having excellent brightness and uniformity can be obtd.

Title: Heater for boiler and others
Inventor: AZUMA YOSHIHIKO
IPC: F24H1/18
Filed: 1978-11-08
Abstract: PURPOSE:To ensure longer life of the heater by directly heating water in a container with constant temperature heating elements made of a barium titanate semiconductor arranged at proper points on the case of the boiler. CONSTITUTION:When a required amount of water is put into the pot 1 and heating elements made of a barium titanate semiconductor is energized, the temperature of the heating surface 51 goes up to heat the water. In the process, due to a characteristic of the heating element 5, a rapid increase in the electric resistance checks further rise of the temperature after a certain temperature is reached. Thus, there is no danger of overheating following the evaporation of the water. Accordingly, even if the voltage applied on the heating element varies, the element itself blocks the current after the certain temperature is reached. Thus, overheating can be eliminated completely.
