Title: Device for producing color frame of video signal
Inventor: SEKIMOTO KUNIO
IPC: H04N9/44
Filed: 1986-04-25
Abstract: PURPOSE:To always implement proper color frame signals, by specifying the phase at the time of frequency dividing by means of color frame signals and horizontal and vertical synchronizing signals separated from input video signals and obtaining synchronizing signals and carriers classified with color. CONSTITUTION:Composite synchronizing signals 12, horizontal synchronizing signals 13, and vertical synchronizing signals 14 are separated from inputted video signals and frame signals are produced. The output signal of a burst gate 2 is frequency-divided and chrominance subcarriers 17 are obtained. The signals 13 become signals 161, 162, and 163 through delayors 71, 72, and 73 and by latching the subcarriers 17 signals 181, 182, and 183 are outputted. When phases of input signals coincide with each other, a gate 23 transmits the signal 182 of intermediate timing to a color frame detector 100 and the detector 100 is operated by a signal obtained by dividing the signals 13 into two and outputs stable color frame signals 19. Therefore, proper color frame signals can be always obtained.

Title: Projective television device
Inventor: MIYATAKE YOSHITO
IPC: G02B13/16
Filed: 1986-04-25
Abstract: PURPOSE:To minimize the difference in resolution by location of a picture projected on a screen so as to improve the picture quality over the entire area, by curving the screen to have a cylindrical form so that the cross-sectional shape of the screen in the vertical direction can form a curve having its concave section on the inside. CONSTITUTION:A screen 32 is cylindrically curved so that its cross-sectional shape in the vertical direction(vertical scanning direction) can have its concave section on the inside. The emitting angles of emitted optical beams 39, 40, and 41 are made parallel with the normal lines of the screen 32 at each point and the inclined angle of the small prism element of the screen 32 makes each optical beam 39, 40, and 41 parallel with each other. Since the optical beams 39 and 40 become oblique against the normal lines at each point in the end sections 42 and 43 of the screen 32, therefore, the ratios b1 /a1 and b3/a3 of the widths of the optical beams decrease. Moreover, the ratio b3/a3 of the optical beams at the end section 43, whose projecting optical path length is longer on the screen 32, becomes smaller when compared with a case where the screen is flat. Accordingly the difference in resolution by location of a picture projected on the screen is minimized and the picture quality can be improved over the entire area.
