Title: Production of substrate type optical waveguide
Inventor: SAKANO TATSUYA
IPC: G02B6/13
Filed: 1989-06-08
Abstract: PURPOSE:To obtain the substrate type optical waveguide of a low loss with excellent mass productivity by simultaneously forming a clad layer and the optical waveguide by thermal diffusion. CONSTITUTION:An SiO2 layer 17 is formed by thermally oxidizing an Si sub strate 11 and a metal or metal oxide 6 to enhance the refractive index of the SiO2 layer 17 is formed thereon to a prescribed shape; thereafter, the metal or metal oxide is thermally oxidized and diffused in an oxidizing atmosphere to simultaneously form a lower clad layer 18 consisting of the SiO2 and the optical waveguide 19 having the high refractive index. Since the generation of roughening on the side surfaces of the optical waveguide 19 is thereby obviat ed, the low-loss optical waveguide is formed and since the lower clad layer 18 is the good-quality SiO2 film formed by the thermal oxidation, the propaga tion loss of the optical waveguide is further decreased. This optical waveguide 19 is low in refractive index and has the refractive index approximate to the refractive index of an optical fiber, the connection thereof to the optical fiber at the low loss is possible. The substrate type optical waveguide 19 which is of the low loss and has the lower connection loss to the optical fiber is obtd. with the excellent mass productivity.

IPC: G06F17/21
Filed: 1982-08-23
Abstract: PURPOSE:To improve the efficiency of KANA (Japanese syllabary)-KANJI (Chinese character) conversion processing, by converting plural KANA character strings at the same time and operating respective devices for dictionary retrieval, concatenation test, etc., simultaneously. CONSTITUTION:An input KANA character string is stored in a storage device 10 for the halfway result of retrieval and test result conversion. A retrieval dictionary determining device 3 fetches the halfway conversion result from the device 10 under the control of a control part 1 to determined a dictionary to be looked up by referring to the contents of a transition table storage device 2, and outputs the halfway conversion result to a halfway conversion result storage device 8. A dictionary retrieving device 5 fetches the halfway result from the device 8 and retrieves one of dictionary storage devices 4-1-4-n by the KANA character string. The device 5 takes a copy 11 of the retrieval result and stores it in a storage device 9 for the halfway result of word conversion. A halfway conversion result updating device 7 fetches the contents of the device 9, and retrieves a concatenation table storage device 6 when succeeding in the retrieval to output KANJI together with added KANA when concatenation is made possible on the basis of grammatical information. In case of a failure of the retrieval, the device 7 sends the halfway result to the device 10 and said operations are repeated to put the respective devices in operation simultaneously.
