Title: Production of batio3 optical single crystal
Inventor: NAKAO SATORU
IPC: G03H1/02
Filed: 1991-12-26
Abstract: PURPOSE:To increase the length of the waveguides for coupling without attenuating light and to eliminate distortions and noises so as to improve an amplification rate by impressing prescribed electric fields to the BaTiO3 single crystal from which 90 deg. domain is removed, thereby forming periodically inverted 180 deg. domain structures. CONSTITUTION:The BaTiO3 single crystal is subjected to a uniaxial compression treatment to remove the 90 deg. domain therefrom. Plural electrodes 10 are provided on the front surface and the rear (C surface) in the polarization direction of this crystal 1 and are periodically arranged in prescribed patterns. Voltages varying in (+) and (-) directions are then impressed to the respective electrodes 10 via lead wires 11 between the adjacent electrodes. Electric fields alternately inverting in a light propagation direction are thereafter impressed to the crystal 1 to form the periodically inverting 180 deg. domain structures. As a result, reference light progresses in a specified relation with the polarization direction and, therefore, the amplification of the signal light arises at all times in the coupling part of the signal light and the reference light. In addition, the reflection of the signal light and the reflection of the noises are prevented.

Title: Convergence control method for projection television receiver
Inventor: CHAUVIN JAQUES
IPC: H04N9/28
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a method which controls the convergence of a projection TV receiver, without causing switch-on disturbances by moving plural markers toward a sensor from the opposite direction and using the average value of plural operation variables as a marker operation variable. SOLUTION: Sensors S are allocated to markers M1 and M2 which are moved toward the sensors S from the opposite sides, i.e., from the left and right. The marker M1 is moved towards the sensor S until the edge of the marker M1 touches the sensor S or begins to cross the sensor S. This movement is shown by an edge (c) of a dotted chain line of the marker M1. At this position, a 1st operation variable corrects the convergence. Similarly, the marker M2 allocated to the right side of the sensor S is moved towards the sensor S until the left edge of the marker M2 touches the sensor S. Thus, a 2nd operation variable is obtained and shifted from the 1st operation variable. The average value of both operational variables is used as the correction value.
