Abstract: PURPOSE:To sufficiently correct aberrations without using a special lens system and to display a virtual image larger than the size of a movable mirror by making beams having the section equal to or larger than the determined divided regions incident directly on a hologram photosensitive material from two directions, thereby exposing this photosensitive material. CONSTITUTION:The laser beam emitted from an argon ion laser 10 is bisected by a half mirror 9 and these laser beams are respectively passed through variable diameter apertures 7a, 7b for controlling luminous flux diameters, by which the beams are shaped to prescribed diameters. The two luminous fluxes are made incident on the same region of the photosensitive material 1 applied or stuck onto a thin glass substrate 2 from the sides opposite to each other, by which a reflection type hologram is recorded. These two laser beams are so adjusted that the respective beam shapes on the photosensitive material 1 to be formed with the hologram align to the hologram region. The beams are simultaneously so adjusted that the incident angles thereof satisfy a prescribed relation. One of the two laser beams always passes the center of a virtually set diaphragm.

Abstract: PURPOSE:To watch a desired program without requiring waiting time by separating and extracting a text signal from a receiving signal by a text signal separation circuit and storing the extracted character signal in a non-volatile magnetooptical disk. CONSTITUTION:An antenna 1 is connected to a channel selection/demodulation circuit 2 and serves to demodulae the video signal of a selected channel. A synchronizing separation circuit 3 separates a horizontal synchronizing signal from a video signal and generates a reference clock for waveform equalization and text signal separation. On the other hand, a waveform equalization circuit 4 forms the waveform of the video signal while referring to the reference clock and outputs it to a text signal separation circuit 5. The text signal separation circuit 5 separates the text signal according to the reference clock and stores it in a buffer area 6-1 provided within a magnetooptical disk 6. The magnetooptical disk 6 is provided with the buffer rear 6-1 and a storage area 6-2. Thus, much television teletext broadcasting can be stored over a long period of time.

Abstract: PURPOSE:To accurately detect an information magnetic domain edge by combining, interfering and focusing a polarized component generated by the rotation of polarization of a reflected light generated by a magneto-optical recording film and a polarized component perpendicular thereto at a suitable optical amount ratio, and detecting it by using divided photodetectors. CONSTITUTION:An optical component (beam flux A) which passes a second polarizing beam splitter 8, passes a 1/2 wavelength plate 10 and reaches a neutral beam splitter 11 and an optical component (beam flux B) which passes an optical path compensation plate 10-2 and reaches the splitter 11 are superposed in the opposite phase on a photodetector 14-21 corresponding to a photodetector 14-11, and superposed in the same phase on a photodetector 14-22. Accordingly, they becomes a distribution of axial symmetry with respect to an optical axis, and a difference of the optical intensity distribution of the flux B including edge information at upper and lower positions through the optical axes thereof can be detected. Thus, edge detecting capacity can be improved.

Abstract: PURPOSE:To achieve a higher accuracy by a method wherein reflected light from an information memory carrier is checked with a bi-splitting light detector and a differential signal is obtained to detect a boundary of bits. CONSTITUTION:Reflected light obtained from an information memory carrier is detected with bi-splitting light detectors 4 and 5. A division line of the light is in a direction at the bi-splitting light detectors 4 and 5 corresponding to that vertical to a track of the information memory carrier. Here, when a light spot shifts to upward magnetization from downward magnetization, a regeneration signal 9 produces a peak signal of a positive value at a position where magnetization is inverted. Conversely, when the light spot shifts to the downward magnetization from the upward magnetization, the same happens. But in this case, a peak signal of a negative value is obtained at a position where the magnetization is inverted. In other words, a signal always moves to 0 or a pit and there is a peak only on the boundary. Thus, effect is limited in difference of transmission characteristic of an optical head or the like depending on a size of a pit thereby eliminating a problem on an edge shift with a smaller change in DC component.

Abstract: PURPOSE:To improve reliability regardless of the dimensional accuracy of mechanical members by providing a transmission limiting mechanism which selectively enters a neutral position in the revolving area of 1st and 2nd planetary gears meshing with 1st and 2nd camera action mechanisms and which stops the engagement with one camera action mechanism. CONSTITUTION:When a switch lever rocks clockwise, a 1st regulating projection part 170b on the upper part separates from a space between a planetary gear 106 and a rewinding gear 110, while a 2nd regulating part 170c on the lower part enters between a planetary gear 28 and a transmission gear 32. Owing to the clockwise rotation of a motor M1, the planetary gear 106 is permitted to revolve in the direction in which it meshes with the rewinding gear 110, thereby rewinding film. On the other hand, the 2nd regulating part 170c inhibits the planetary gear 28 from revolving in the direction in which it meshes with the transmission gear 32, thereby inhibiting film winding. Since the transmission limiting mechanism which selectively enters the neutral position of the revolving area of the planetary gears, reliability can be improved greatly regardless of dimensional accuracy.
