Title: Optical shutter array
Inventor: ASAI TAKAHIRO
IPC: G02F1/055
Filed: 1981-12-22
Abstract: PURPOSE:To arrange the modulated beams due to plural ferrodielectric substrates on a line with no junction of these substrates, by providing ferrodielectric materials having the secondary optical effects to the two surfaces which hold the polarizing surface of a PBS with a space so that they are opposite to each other. CONSTITUTION:The PLZT optical shutter elements 3 and 3' are set with a space on the two surfaces which hold the polarizing surface of a PBS (polarized beam splitter) 7 so as to be opposite to each other. For the elements 3 and 3', the electrodes are provided opposite to each other in the direction which is tilted 45 deg. to the direction of array. The light polarized in the array direction of the element 3 and made incident to the element 3 is reflected by a polarizing film and delivered to the lower part when no electric field is applied between electrodes. With application of the electric field, a 90 deg. polarizing surface is turned by the element 3. Thus the reflected light travels straight through the polarizing surface. In the same way, the polarized light which is incident to the element 3' is reflected by or transmits through the polarized surface in accordance with the presence or absence of voltage and then delivered from the PBS7. Thus the modulated beams are arranged on a line.

Title: Optical head device
Inventor: TAKAHASHI JUNICHI
IPC: G11B7/131
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To detect multi-valued information without generating the differences of reproduced signal amplitudes by the structure of optical recording mediums multi-value recorded in a height direction and to make a multi-valued information recording medium a large capacity. SOLUTION: The light reflected in accordance with information recorded on an optical disk 10 is transmitted through an objective lens 4 and a beam spitter 3 to be made incident on a photodetector 6 by being passed through a hologram optical element 5. The hologram optical element 5 has such a constitution that the height difference of reproduction pits are diffracted into 1st-order diffracted lights and the diffraction in a pit having a reference height is recorded as a 0-order diffracted light and diffractions having different pit heights are recorded as the 1-st order diffracted lights. A 0-order diffracted light (a) is made incident on the photodetector 6, a plus 1-st order diffracted light (b) is made incident on a photodetector 7 and a minus 1-st order diffracted light (c) is made incident on a photodetector 8.  The multi-valued information are reproduced with uniform performances by remarkably reducing variation of reproduced signal-to-noise ratios due to differences in the pit height direction.

Title: Carrier recovery circuit
Inventor: NINOMIYA YUICHI
IPC: H04B14/04
Filed: 1985-09-20
Abstract: PURPOSE:To stably recover a carrier necessary for demodulating a PSK modulation signal by permitting a sample holding circuit to hold the control voltage of a voltage controlled oscillator VCO stable. CONSTITUTION:While a synchronization detecting circuit 11 detects the synchro nization between the PSK modulation signal and the output signal of the VCO 10, a switch 14a at the input side of the sample holding circuit 14 is in an ON state, and a charge is charged and discharged to a capacitor 14b. While the input signal of the synchronization detecting circuit 11 is an FM modulation signal, the input side switch 14a is an OFF state, and the output of the sample holding circuit 14 becomes a constant voltage due to the charge of the capacitor 14b. the oscillation frequency of the output signal of the VCO 10 is controlled by the output voltage of the sample holding circuit 14. However, since the output voltage of the sample holding circuit 14 has less fluctuation, the output signal of the VCO 10 is stable. Accordingly, while the output signal of a band amplifier 8 is the PSK signal, the synchronization detecting circuit 11 can stably detect the synchronization at the beginning of said period.
