Title: Method for building localized bragg gratings into semiconductor
Inventor: BODERE ALAIN
IPC: H01S5/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To form localized Bragg gratings into a semiconductor component by placing a second mask having parts for limiting the positions of the gratings apart a spacing from a resin layer, then executing supplementary irradiation. SOLUTION: After the resin mask is obtd. by holographic exposure and development, the second mask is placed apart from this resin layer thereon. At least one surface facing the direction of the resin of the surfaces of this mask is provided with parts E which are reflection surfaces. Next. the surface of the component is exposed through this mask. Since the rear surfaces of the parts E reflect, the resin existing in the lower positions is partially irradiated with the energy decreasing the further from the edges of the parts E. The laser parts have such a mask which is increased in the width 7'a, 7'b, 7'c of the open parts thereof in boundary zones and the increase in the width of the one parts eventually leads to a decrease in the depth of etching and, consequently, the transfer effect is compensated.

Filed: 1992-12-25
Abstract: PURPOSE:To obtain a correct counted value even when a system clock is generat ed at any timing by deciding whether or not the presence of leading and trailing of a counter clock for a half period of a system clock back to a prescribed 1st timing when a counted value is obtained. CONSTITUTION:When the counter with output latch function is operated, whether or not the presence of leading and trailing of a counter clock is present for a half period of a system clock back to a prescribed 1st timing when the counted value is latched is decided. When not in presence, since the counted value is confirmed at the point of time of a 1st timing, the counted value is immediately latched, and when in presence, since it is possible that the time is the moment when the counted value is being updated the counted value is latched in a 2nd timing delayed by a half period. Thus, the counter 100 is provided with a deciding circuit 14 and a latch control circuit 15, etc.

Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To quickly evade the interference and to carry on the communication without changing the radio frequency of plural transceivers against occurrence of the interference. SOLUTION: A radio base station 500 periodically retrieves the fresh interference evading destination radio frequency after sensing a carrier via a receiving circuit 503c and stores these retrieved radio frequency in a storage means 502c. The station 500 also reports and stores the fresh evading destination radio frequency which are periodically retrieved by the report signals to its follower radio mobile station. When the station 500 or the follower mobile station detects an interference disturbance, both stations quickly switch the operating radio frequency to the interference evading destination radio frequency to evade the interference without switching a transceiver unit TRX.
