Abstract: PURPOSE:To simultaneously obtain a color image reproduced by combining yellow, magenta and cyan by using a single white color light source, executing the modulation at every color, and thereafter, synthesizing them to a white color light again and exposing it to a photosensitive and pressure sensitive sheet by a scanning optical system. CONSTITUTION:A light beam emitted from a light source lamp 30 for radiating what is called a white color light containing color components of red(R), green(G) and blue(B) is reflected by an elliptical surface mirror 32 and made incident on a concave lens 34.

Title: Three-dimensional display device
Inventor: YOSHIKAWA NOBUYOSHI
IPC: G09G3/02
Filed: 1992-07-31
Abstract: PURPOSE:To make bright display with high resolution even if low-output light sources are used by intermittently irradiating a rotary screen with light rays in correspondence to the arrival time of this screen at a prescribed display position. CONSTITUTION:The light ray irradiation section is constituted of light source sections 10 and a transmission system 20. The light source sections 10 are constituted by laminating the plural light sources, for example, red laser diodes 11 in such a manner that these diodes correspond to the respective coordinate points of the X-Y axis of the rotary screens 31a, b. The laser beams L from the ray irradiation section are cast into the screens 31a, 31b to form bright points and the three-dimensional videos are produced by the after-images of the brightness. Namely, the many screen images (bright points) by the laser beams L, etc., are formed while the rotary screens 31 make one turn and the assembly thereof is the three-dimensional image. Since the plural light source parts 10 corresponding to the coordinate bright points of the X-Y of the rotary screens 31 are adopted for the light sources, there is no need for scanning and the control thereof is easy. The bright display is thus possible even with the low-output light sources.

Title: Television receiver
Inventor: KAMEMOTO KAZUHIRO
IPC: H04N5/16
Filed: 1988-09-09
Abstract: PURPOSE:To suppress an event such that a white peak level signal is abnormally bright by using a voltage appearing at one terminal of an anode current detection resistor for suppressing the white peak signal directly. CONSTITUTION:The anode current detection resistor R1 is connected between other terminal of a primary winding L1 of a flyback transformer being a high voltage circuit and other terminal of a secondary winding L2. The voltage appearing at one terminal of the anode current detection resistor R1 is used directly to suppress a white peak signal. Thus, the suppression level of the white peak signal in a low brightness region where the modulation of a luminance signal is small changes low when the brightness is low and high as the brightness gets higher. Then even if the white level changes suddenly by the automatic brightness control (ABL) and the automatic contrast control (ACL) when the ABL and ACL are in operation, the suppressing level of the white peak signal is changed accordingly and the sudden change in the brightness is not sensed.
