Abstract: PURPOSE:To execute rapid retrieving operation by retrieving a duplicated character code when a character string including a duplicated character is retrieved. CONSTITUTION:A whole control part 9 discriminates whether a duplicated character exists in a registered keyword KEYWORD or not. Namely, the leading character of the keyword through the final character of the keyword are successively compared with a duplicate start code DUPST (D1), and when the character coincides with the code, i.e. when the duplicated character exists in the keyword, the leading character code in the character string to be retrieved in a storage device 4 is extracted. The extracted character code is compared with the DUPST. In case of dissidence, the succeeding code is extracted. In case of coincidence, the leading character code of the keyword is compared with a character POS2 backed from the DUPST position extracting the character code at present out of the character string to be retrieved by a several characters. In case of coincidence, characters (C1-C7) to be retrieved corresponding to the 2nd character and after of the keyword are successively compared, and when all the characters coincide, the retrieval is ended.

Abstract: PURPOSE:To generate a required signal phase shift stably and more accurately independently of an input frequency by selecting the outputs of plural phase shift circuits and applying the output to a hue adjusting circuit. CONSTITUTION:A phase shifter A 1a selects a cut-off frequency decided by the constant of R1 38, R2 39, C1 40 and C2 41 to be 3.58MHz and a phase shifter B 1b selects a cut-off frequency decided by the constant of R1 38, R2 39, C1 40 and C2 41 to be 4.43MHz. Thus, continuous wave signals 11a, 12a being the outputs of the phase shifter A 1a are generated into signals phase-shifting to a 3.58MHz input signal by +45 deg. and -45 deg.. Moreover, continuous wave signals 11b, 12b being the outputs of the phase shifter B 1b are generated into signals phase-shifting to a 4.43MHz input signal by +45 deg. and -45 deg.. Switches 4a, 4b in interlocking with each other lead the output of the phase shifter A 1a to a hue adjusting device 2 when they are turned to the position 1 and lead the output of the phase shifter B 1b to the hue adjusting device 2 when they are turned to the position 2. Thus, required signal phase shift is applied independently of the frequency.
