IPC: G02B26/12
Filed: 1986-12-27
Abstract: PURPOSE:To reduce the influence of uneven cutting to be exerted upon a scanning mirror surface by arranging a 1st slit having long sides in an optical beam scanning direction and short sides in its rectangular direction between a scanning mirror and an image forming optical system and arranging a 2nd slit in front of an image forming face. CONSTITUTION:In the optical scanner, a slit A is arranged between a polygon mirror 9 and an image formation lens 10 and a slit B is arranged between the lens 10 and a recording film 11. The slits A, B are the means for restricting diffraction beam component in the direction intersecting with the scanning direction and their aperture are formed so as to have long sides in the scanning direction and short sides in the intersecting direction. When laser beams are radiated from a light source 1 to the polygon mirror 9, diffraction is generated by the uneven cutting work on the reflecting face of the mirror 9, but the influence of the uneven cutting to be exerted upon the scanning mirror surface can be reduced by arranging the slits A, B for transmitting 0th-order diffraction light.

Filed: 1990-11-19
Abstract: PURPOSE:To perform a stable tracking operation for a target track by detecting a speed of an objective lens in traversing tracks at the time of completing the movement and giving driving force in the reverse direction in proportion to the track traversing speed. CONSTITUTION:When the objective lens 10 is to be moved in the radial direction of a medium by plural tracks, a switch SW1 which had been closed is opened, and a switch SW2 is closed instead. By closing the switch SW2, a speed servo loop is formed, and the objective lens 10 is moved in the radial direction at a speed corresponding to an output voltage of a reference voltage generator 5. Now, a voltage in proportion to the moving speed of the objective lens 10 is generated by a speed detector 4 with a track error signal from a track error signal detector 2. When the movement of the objective lens 10 is to be fininished, the switch SW2 is opened, and the switch SW3 is closed, so that an output of a brake pulse generator 7 is outputted to an amplifier 8 to act as a brake upon the objective lens 10. By this method, stable tracking can be carried out.

Title: Synchronizing separator circuit
Inventor: YADA TOSHIAKI
IPC: H04N5/08
Filed: 1989-12-01
Abstract: PURPOSE:To attain stable synchronization separation by applying SYNC tip clamp to an inputted video signal, amplifying a synchronizing signal portion and expanding a margin with respect to a threshold level detecting the synchronizing signal. CONSTITUTION:A video signal is inputted to a terminal 1 of a SYNC tip clamp part a through an externally mounted capacitor C1. The SYNC tip of a video signal at the terminal 1 is clamped to a level lower by a base-emitter voltage Vbe of a transistor(TR) Q1 from a voltage of a constant voltage source V1. The clamped video signal is inputted to a base of a TR Q8 of an amplifier section c through an emitter follower Q2. TRs Q8, Q9 and resistors R2, R3 form a differential amplifier. TRs Q10, Q11 are in pairs with TRs Q2, Q1 to eliminate an offset of a DC voltage inputted to the differential amplifier. The voltage of the constant voltage source V3 is set to amplify the synchronizing signal portion of the video signal. Thus, since a threshold level of the comparator crosses the vicinity of the center of the synchronizing signal portion as shown in waveform diagram b, the margin is increased.
