    Abstract: PURPOSE:To prevent a sound break, a sound skip, noise generation, etc., from being caused at a splicing part even if a film has the splicing part. CONSTITUTION:Address codes are provided in the longitudinal direction of the film 1 and address codes and an acoustic signal which is synchronized with the film image are recorded even on an optical disk 20. While the fading out circuit 16 of a fader 14 is activated once a discontinuous part of the film 1 is detected, track servocontrol over the optical disk 20 is performed and when the addresses of the film 1 and optical disk 20 are matched with each other, the fade-in circuit 15 of the fader 14 is activated.

    Abstract: PURPOSE:To reduce the size of a rotary polygonal mirror and to lower the rotating speed by reflecting the exit light from the rotary polygonal mirror which equally divides a laser beam in a prescribed reflecting part so as to be made incident again to the rotary polygonal mirror and executing plural times of deflection scanning during respective one scanning cycle divided by the number of faces of the rotary polygonal mirror. CONSTITUTION:A sectorial optical path-parallel optical path converting means 21 is provided on the reflection deflecting optical path obtd. by incidence of a laser beam l1 to the rotary polygonal mirror 10. The reflection deflecting scanning beam l2 spreading in a sectorial shape is converted to collimated scanning beams l3 by this converting means 21. The beams l3 are divided to the deflecting ranges of two regions and the collimated scanning beams in the respective divided ranges are reflected and turned back respectively by 1st and 2nd reflecting parts 22a and 22b or 23a and 23b. The turned back beams are returned to the sectorial deflection scanning beams by the converting means 21 and are made incident again to the mirror 10. Plural times of the deflection scanning are executed during the respective one scanning cycle divided by the number of faces of the mirror 10. The size of the rotary polygonal mirror is reduced in this way and the rotating speed thereof is lowered.

    Abstract: PURPOSE:To make the acoustic pressure frequency characteristic flat and to reduce the nonlinear distortion by feeding back oscillation system displacement information of a speaker, which is detected by a laser light interferometer, to a driving system of the speaker. CONSTITUTION:Displacement information of a diaphragm detected by a photodetector 7 of the laser light interferometer is supplied to a preamplifier 11 and a comparing circuit 12 for waveform shaping, and this output is supplied to an up/down counter 13 together with the output of a direction discriminating circuit 14. The output signal from the counter 13 is converted to an analog signal by a D/A converter 15 and is supplied to a differential amplifier 16. The digital audio signal supplied to an input terminal 17 is converted to an analog signal by a D/A converter 18 and is compared with a reference voltage passing through a sound band limiting filter 19. The comparison error signal from the differential amplifier 16 is supplied to a driving coil 8 through a phase compensating filter 20 and a driving circuit 21 of the speaker.

    Abstract: PURPOSE:To ensure the accurate beam landing of each line and to simplify the circuit constitution despite the inferior vertical deflection linearity, by compensating the beam position from an error of beam position set before a 1H delay when the horizontal scan is started. CONSTITUTION:Plural belt-shaped color fluorescent material lines 3 are extended toward an arrow X, i.e., the main scanning direction of an electron beam on the inner surface of a screen 2 which functions as a display screen of a CRT. At the same time, odd and even numbers of field lines are arrayed alternately with a fixed pitch P toward an arrow Y in the secondary scanning direction orthogonal to the lines 3. Then a guard band 4 having no emission of light is formed between lines 3, and furthermore an index line 5 is formed with every 2nd band 4. A beam position compensation control circuit detects the volume of the electron beam to the line 5 and compensates the electron beam position in the secondary scanning direction. The lines 3 which are contiguous to each other at one side of the line 5 are defined as odd field drives while defining the adjacent lines 3 at the other side of the line 5 as even field drives respectively.

    Abstract: PURPOSE:To provide a projective laser image display device which makes high- output image display possible while miniaturizing a projector. CONSTITUTION:Laser light sources 1a, 2a and 3a for emitting laser beams in green are used for light sources 1, 2 and 3 and further, wavelength converters 1b and 3b excited by the laser beams of green so as to generate high-output red laser beams or ultraviolet laser beams are also used for the light sources 1 and 3. Thus, visible laser beams L1 and L2 in red and green are outputted from the light sources 1, 2 and 3, invisible ultraviolet laser beams L3 are outputted respectively, and images of red and green are displayed on a screen 11a coating the screen, which is irradiated with the laser beams L1, L2 and L3 of a screen 11 paired with the projector, with a phosphor excited by ultraviolet rays and emitted in blue and by irradiating the screen 11a with the laser beams L1 and L2. Then, the image in blue is displayed on the screen 11a by exciting the phosphor by irradiating the screen with the laser beam L3.

    Abstract: PURPOSE:To provide an information recording medium without losing the sense of sequence at the time of reproducing even when the sequential information signals of a video signal, etc., are recorded on plural information recording media or recording planes and to provide an information reproducing device suitable to the signal reproduction of such information recording media. CONSTITUTION:An information signal recorded on the last track of an optical disk 2A is recorded on the first track of an optical disk 2B, as well. Then, a control flag is recorded on the starting position of the last track of the disk 2A. When a control flag detection signal is received, a switching control signal is outputted to switches 14A and 14B by a system controller 16 after a specified passage of time, the switch 14A is turned off and the switch 14B is turned on. Thereafter, the information signal read out from the first track of the optical disk 2B by an optical pick-up 6B is reproduced.

    Abstract: PURPOSE:To lessen unnecessary radiation interference and to increase sufficiently the luminance of a picture image, by scanning two electron beams to perform the reproduction of a line sequential color picture image by two-color simultaneous light emission. CONSTITUTION:A continuous index line 35 along a horizontal scanning direction is arranged in the vertical scanning direction, and two electron beams scan a screen 23 where color phosphor lines 31-33 having different colors respectively are arranged and formed along both sides of each index line 35. Based on an index signal obtained from the index line 35, the said two electron beams are landed on each color lines 31-33 on both sides of the index line 35. At the same time, colors are switched for every index line 35 to perform the reproduction of a line sequential color picture image by two-color simultaneous light emission. Since the line sequential color picture image is reproduced by two- color simultaneous light emission by scanning two electron beams, brightness can be made to about 4 times in comparison with an index type color cathode- ray tube of a system in which a point sequential color picture image is reproduced by scanning one electron beam.
