Title: Optical waveguide device
Inventor: KIYONO MINORU
IPC: G02F1/035
Filed: 1991-08-28
Abstract: PURPOSE:To improve a modulation band area by decreasing the dielectric constant of a buffer layer between an optical waveguide and an electrode and increasing the speed of the microwave of a signal voltage by eliminating the lower part of the electrode in the buffer layer partially. CONSTITUTION:The buffer layer 14 of SiO2 is provided on the optical waveguide 12, and the electrodes 16, 18 are provided on the buffer layer 14 in accordance with the positions of intermediate waveguide parts 12c, 12d. An electric line of force arrives at the electrode 18 from the electrode 16 via the buffer layer 14 and a substrate 10, however, a part 22 from which the buffer layer 14 is eliminated exists on the route of the electric line of force, and the electrode 16 is enclosed with the air. Since the air is provided with refractive index and dielectric constant less than that of the material of the buffer layer 14, the speed of the microwave of the signal voltage is increased than that in the case where it advances through the material of the buffer layer 14. Therefore, since most of the electric lines of force passing the area of the buffer layer 14 of the signal voltage pass through the optical waveguide 12 at speed more than ever, the modulation band area of an optical waveguide device can be improved.

Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To provide an image coding system in which a multi-point control system is easily realized by connecting a plurality of multi-point controllers sending a plurality of multiplexed image signals. SOLUTION: An image coding section 11 interleaves a frame of an image signal to configure N-sets of sub frames among N-sets of multi-frames and tentatively encodes the image signal as required to measure an amount of a image code signal. Furthermore, an image decoding section 31 decodes sequentially the image code signal to obtain sub-frames and interpolates them to reproduce the image signal. A video conference terminal equipment 10 receives an image code signal from other terminal equipment and decodes the signal to reproduce the image signal and selects the image signal to be sent to each terminal equipment upon request from the terminal equipments and encodes sequentially the sub frames obtained through interleave processing and sends the coded frames to the terminal equipments.  In this case, one frame denotes an image for a specific station and the frames are arranged at random. Moreover, each of a plurality of multi-point controllers (MCU) sends an image for a station in its own group.
