Title: Liquid crystal color projection device
Inventor: INADA TOMOHIDE
IPC: H04N9/31
Filed: 1989-09-21
Abstract: PURPOSE:To make a screen bright by generating a 90-degree rotatory light beam and a non-rotatory light beam in accordance with the displayed video of a liquid crystal display means, reflecting and mixing both beams and then expanding and projecting video light transmitted through or reflected on a polarizing beam split means in a projection optical means. CONSTITUTION:Voltage is selectively supplied to the X and Y electrodes 58 and 59 of liquid crystal boards 51-53 in accordance with the inverted video of an optional video which should be projected. In the case that the light beams 45, 48 and 49 of RGB colors which are linearly polarized are made incident, the light beam made incident on a liquid crystal cell 56 to which the voltage is supplied is transmitted through the liquid crystal as it is and reflected by a reflector 57 but the light beam incident on the liquid crystal cell corresponding to a part where the voltage is not supplied is rotated by 90 degrees with the aid of rotatory polarization and reflected by the reflector 57. Therefore, the light which is rotated by 90 degrees, that is, only the video light 50, is transmitted through the polarizing beam split means and projected on the screen by the projection optical means 54, so that a color video is reproduced. Thus, the light quantity of a light source is increased and the screen is made bright.

Title: Formation method of uniaxially-magnetic-anisotropy magnetic thin film
Inventor: OGISO YOSHIFUMI
IPC: H01F10/28
Filed: 1991-09-24
Abstract: PURPOSE:To form a stable uniaxially-magnetic-anisotropy magnetic thin film by a method wherein the film is not formed in a magnetic field and a board to which a grating has been executed is not used. CONSTITUTION:A film is formed of a magnetically anisotropic magnetic material on a board whose coefficient of thermal expansion is anisotropic. Consequently, after the film has been formed and when the board is cooled down to room temperature, the film is contracted in one direction according to the anisotropy of the coefficient of thermal expansion. Thereby, the film is magnetized in one direction by the reverse magnetostriction effect of the magnetic film and its uniaxially magnetic anisotropy is displayed.

Title: Variable-color lighting system
Inventor: HAMAMOTO KATSUNOBU
IPC: H05B37/02
Filed: 1992-09-14
Abstract: PURPOSE:To reduce the drift of the illumination light of mixed colors against the setting without increasing the number of stored light quantity data. CONSTITUTION:When the light quantity data are small, the dimming signal is outputted from only a D/A conversion section 11a. When the light quantity data are large, the digital value subtracted with the data of a reference data setting section 9b from the light quantity data is converted by a D/A conversion section 11c, and analog signals from the D/A conversion sections 11a, 11c are added by a signal adding section 13. The added signal is outputted as the dimming signal. The dimming ratio change widths of light sources 2R, 2G, 2B are reduced when the dimming level is low, and they are increased when the dimming level is high. Fine setting can be made when the light quantities of the light sources 2R, 2G, 2B are small.

Title: Encoding and decoding system for coordinate signal
Inventor: MIYASATO TSUTOMU
IPC: G06F3/0488
Filed: 1985-11-01
Abstract: PURPOSE:To improve encoding efficiency and to suppress deterioration in picture quality by encoding a signal by degeneration to coordinate points of a coordinate system with low resolution during transmission and decoding the signal by using a dynamic programming method during reception. CONSTITUTION:X and Y coordinate signals inputted from terminals 1 and 2 are processed and encoded by degenerating respective coordinate points to coordinate points of a coordinate system which has lower resolution than an original coordinate system, so that the encoded signals are outputted from a multiplexing parallel-series converter 11. A reception part, on the other hand, performs decoding operation by the dynamic programming method so that coordinate values which form a segment close to a straight light are outputted as real coordinates between the received coordinate points and degenerated coordinate points; and the coordinates are outputted from a D/D decoder 18. Consequently, the encoding efficiency is improved and deterioration in picture quality is suppressed.
