Filed: 1982-09-07
Abstract: PURPOSE:To attain a high-capacity and inexpensive waveguide type optical modulator, by providing one channel optical waveguide, an ion exchange layer around the optical waveguide, and a means which applies an electric field into the optical waveguide. CONSTITUTION:A linearly polarized light 5 which is made incident to a channel optical waveguide 2 and is parallel with a substrate applies a voltage 6 to electrodes 4 which face to each other with the optical waveguide 2 between them, When the voltage is applied to electrodes 4, the light incident to the channel optical waveguide 2 is converted to a radiant light spreading to ion exchange layers 3 according as it is propagated on the optical waveguide 2, and this radiant light disappears by attenuation due to electrodes 4. when no voltage is applied to electrodes 4, the incident light 5 is guided on the waveguide 2 and is emitted without attenuation. The intensity of light which is guided on the waveguide 2 and is emitted is changed in accordance with the magnification of the applied voltage 6 to modulate the intensity of light. Thus, a high-capacity and inexpensive waveguide type optical modulator is attained.

Title: Digital low pass filter
Inventor: SASAKI TAKU
IPC: H04N9/64
Filed: 1988-06-22
Abstract: PURPOSE:To reduce the circuit scale by using a delay and a tap of a low pass filter for luminance signal in common part of delay and tap of a low pass filter for chrominance signal in horizontal or vertical direction. CONSTITUTION:A switch 10 selects R, G, B signals synchronously with a clock and a luminance signal is outputted. The output is given to a low pass filter comprising delay devices 11-14. When the switch 10 is switched by the clock, the output subject to low pass filtering to the signals R, G, B is obtained alternately to the output of adders 24, 25 and a coefficient device 21. Thus, when they are switched by using a switch 28 synchronously with the clock, the output subject to low pass filtering as to the R, G, B signals is obtained separately. Moreover, since the signal output is obtained in real time similarly to a chrominance signal, no delay circuit for matching the time between the luminance and chrominance signals is not required.

Filed: 1994-07-07
Abstract: PURPOSE:To shorten the time until becoming a recordable/reproducible state by repeating zone frequency decision sequence with a short processing time when no ID is detected from a regenerative signal at a reproducing frequency corresponding to a first disk format.
