Title: Digital modulation signal receiver
Inventor: KAWAI SATOSHI
IPC: H04L27/227
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To normally receive a digital modulation signal without unlocking QPSK demodulation even when a PLL circuit corrects a local oscillation frequency at the reception of the digital modulation signal at a high bit rate. SOLUTION: The digital modulation signal receiver is provided with an IQ demodulator 3 that has two mixers 3a, 3b receiving a digital modulation signal, a voltage controlled local oscillator 4 that gives a local oscillation signal with a frequency nearly equal to a carrier frequency of the digital modulation signal to the mixers 3a, 3b, a PLL circuit 10 that outputs an error signal on the basis of a reference frequency signal and the local oscillation signal, a low pass filter 14 that smoothes the error signal to supply a control voltage to the local oscillator 4.  The receiver is configured to change a frequency of the reference frequency signal, increases the frequency of the reference frequency signal more than a prescribed frequency when a transmission rate of the digital modulation signal is lower than a prescribed transmission rate and decreases the frequency of the reference frequency signal lower than the prescribed frequency when the transmission rate of the digital modulation signal is higher than the prescribed transmission rate.

Title: Kana/kanji converter
Inventor: IKUTA JUNZO
IPC: G06F3/02
Filed: 1989-09-29
Abstract: PURPOSE:To reduce the possibility of misconversion by outputting the KANJI (Chinese character) candidates of higher preference ranks in terms of the connecting relation with the character string set right before the inserting position of the KANA (Japanese syllabary) data. CONSTITUTION:When a KANA/KANJI conversion key of an input means is pushed after the end of input of KANA, an editing control part 3 sends an instruction to a KANA/KANJI conversion control part 7. Thus the KANA/ KANJI conversion is applied to the KANA character strings stored in an input KANA train storage part 2. The part 7 performs this conversion operation by reference to the grammar information stored in a pre-contact grammar information storage part 6, an inter-part-of-speech table 4, and a word dictionary 5. At the same time, a word which is corrected by the several head characters of the input KANA train is retrieved out of the dictionary 5. Thus the first word candidate is obtained. Then it is decided whether each candidate can be connected to a pre-contact word or not by reference to the table 4 and the part 6. Then the KANA/KANJI conversion operations are successively carried out. As a result, the candidates of KANJI-KANA mixture sentences are obtained.

Abstract: PURPOSE:To aim at the promotion of energy-saving in an apparatus, by constituting it having a device detecting feed of the specified length of a tape material and a controlling device which sets a period of the feed of the detected specified length down as a cycle and makes it periodically drive this detecting device. CONSTITUTION:Each time an ink ribbon 2 is fed as long as the specified length equal to that of its traveling route ranging from a detection position of a terminal detector 14 to a recording position of a thermal head 3, it is made to perform detecting motion in the terminal detector 14 of a recording/terminal detecting part 19. In this case, detection for whether the ink ribbon 2 is fed as far as the said length or not is carried out in a way of counting the number of letters to be recorded with this length with a counter 20 installed in a control part 17. Therefore, driving time of the terminal detector 14 inclusive of a continuous rating current for a light emitting element is sharply reduced, leading to the promotion of energy-saving.
