Filed: 1989-11-29
Abstract: PURPOSE:To improve the integration degree of the optical circuit and to save the space and improve the functions by arranging plural core layers which have rib parts on one substrate in three dimensions. CONSTITUTION:The core layers 2 and clad layers 3 are laminated alternately on the substrate 1, each core layer 2 projects upward to form the rib part 2a which extend in one direction integrally. Each core layer 2 is upper, middle, and lower stages forms 2, 1, 2 pieces of rib part 2a, respectively, and the core layer 2 and rib part 2a has higher refractive indexes than the clad layer 3 and substrate 1. Therefore, a light beam B is confined to the core layer 2 vertically because of the refractive index difference between the core layer 2 and air or the clad layer 3 and the refractive index difference between the core layer 2 and substrate 1 or clad layer 3, and also confined to right below the rib part 2a horizontally because the effective refractive index of the part right below the rib part 2a is higher than that of its peripheral part. Consequently, the device is reduced in size, improved in the degree of freedom of the shape, and improved in function.

Title: Sampling time synchronization system
Inventor: SHUDO ITSUO
IPC: H04L7/00
Filed: 1988-12-07
Abstract: PURPOSE:To cause sampling periods of time to coincide accurately with each other by making the directions of transmission through two transmission routes opposite to each other and by performing a synchronous control through using a difference in the time of arrival of a transmitted signal. CONSTITUTION:When a signal is sent at the same time TS in opposite directions from a master station 2 to two loop transmission routes, said signal makes a round of all branch stations and returns to the master station 2. The master station 2 sends sampling synchronous flags, measures the time tLP required for each flag to go round said loop, and transmits said time to each branch station. The periods of time tR, tL required for each branch station to receive two clockwise and anticlockwise synchronous flags are equal to a transmission delay time. The total of said periods of time is equal to the time tLP required for each flag to go round said loop. The difference tR-tL in the flag-receiving time can be measured accurately by each branch station and the delay time tLP is transmitted from the master station, so that sampling periods of time can be caused to coincide accurately with each other when a synchronous control is performed by said branch station.
