Title: Orthogonal two-frequency light generating device for optical heterodyne detection
Inventor: MORITO YUKO
IPC: H04B10/516
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To freely set a beat frequency to order of 10<0> to 10<4> Hz for optical heterodyne detection and to reduce effect of noise. SOLUTION: A birefringent single-mode optical fiber 5 wound around a couple of optical fiber winding holders 3A and 3B provided on both the end sides of a supermagnetostrictive rod 7 is expanded and contracted in specific cycles by expanding and contracting the supermagnetostrictive rod 7 by supplying a saw-tooth driving current of specific frequency to a solenoid coil 6. When linear polarized laser light is made incident on this optical fiber 5, lights Ex and Ey of two modes having orthogonal polarizing directions are emitted from its projection end 5out. Retardation between the modes varies up to 0 to 2π according to the tilt angle of the saw-tooth driving current and those lights Ex and Ey are put one over the other to obtain a photocurrent of specific beat frequency.  This beat frequency is determined by the frequency of the driving current, so it can freely be varied to order of 10<0> to 10<4> corresponding to response characteristics of the supermagnetostrictive rod 7.

Title: Tilt mechanism for optical pickup
Inventor: YOKOTA TAIZO
IPC: G11B7/09
Filed: 1988-12-28
Abstract: PURPOSE:To cancel the dislocation quantity of perpendicularity between an optical axis and an optical disk recording surface caused by the rotation of a optical block by setting the turning instantaneous center of the optical block toward a disk center side away from the optical block. CONSTITUTION:The turning instantaneous center of an optical block 8 is set toward the disk center side away from the optical block 8. The optical block 8 turns around a point where the extention lines of linking members 9 and 10 are intersected with each other as the instantaneous center, and since the linking member 10 is shorter than the linking member 9, at the time of turning, the optical block 8 slants its optical axis toward the outer peripheral side of an optical disk 3. When deflection is generated on the outer peripheral side of the optical disk 3, the dislocation quantity of the perpendicularity between the optical axis and the recording surface of the optical disk 3 is detected, the revolution of a motor is controlled according to the dislocation quantity, and thus the optical block 8 is turned downward. By the turning of the optical block 8, the optical axis of an objective lens 8a supported by the block 8 tilts toward the outer peripheral side in a radial direction by a constant quantity, and the dislocation quantity of the perpendicularity between the optical axis and the optical disk 3 recording surface can be canceled.

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To reduce a time required to replace image data by making a transmission request even when re-transmission of AV data once stopped is not finished in the case of stopping reproduction and reproducing new AV data. SOLUTION: During reproduction of AV data, the user stops reproduction by an operation panel 3 and makes a request of new V data. A control means 9 uses a buffer management means 8 to select 'buffer write stop', accesses a host station 6 via a communication interface 2 and stops the transmission and makes a transmission request of new AV data. Simultaneously reproduction of AV data by an AV data processing unit 12 is stopped. Then a data input means 7 detects the end of transmission from a host station 6 and the buffer management means 8 selects a 'buffer write enable state', restarts write of new AV data sent in succession to the transmission end signal to the buffer memory to start reproduction of the AV data. Thus, a time required for replacement of image data is reduced.
