Title: Character procession device
Inventor: MASAKI KATSUMI
IPC: G06F17/21
Filed: 1980-05-08
Abstract: PURPOSE:To prevent erroneous conversion and the occurrence of an excessive retrieval time, by judging a character string to be divided abnormally if a specific number or more of groups consisting of a specific number or less of characters is continuous to form the character string. CONSTITUTION:In case that the first character string such as Kana (Japanese syllabary) is subjected to processings such as conversion to Kanji (Chinese character), English, etc., it is effective that the first character string is processed after it is divided into plural the second character strings. However, if the first character string, for example, ''      '' is converted to ''  '', ''  '' and ''  '', erroneous Kanji is output or the number of combinations of pertinent Kanji becomes large or much time is spent for retrieval. Consequently, when a specific number (3 in this case) or more of the second character strings consisting of a specific number (2 in this case) or less of pronunciations is continuous, for example, in case of division into ''  '', ''  '' and ''  '', the flag 0 is stood by the abnormal division check. Abnormal division is detected by checking whether this flag is stood or not.

Abstract: PURPOSE:To increase the purity of a reference clock by reducing a jitter component as preventing lock-out from occurring by deciding the stability of a loop, and switching a loop gain and a loop time constant. CONSTITUTION:When a delay locked loop(DLL) circuit 1 starts a pull-in operation by controlling the operating timing of the delay locked loop circuit 1 and that of a demodulation circuit 2 by a timing controller circuit 3, the operation of the demodulation circuit 2 can be started almost simultaneously, and they are locked almost simultaneously. Also, a spread spectrum modulation signal is reversely spread by the DLL circuit 1 as switching the loop gain of the DLL circuit 1 and the loop time constant sequentially, and a reverse spread signal outputted from the DLL circuit 1 is demodulated by the demodulation circuit 2. When the DLL circuit 1 is unlocked, the operation of the demodulation circuit 2 is stopped almost simultaneously. Thereby, it is possible to improve the purity of the reference clock as preventing the lock-out from occurring.

Abstract: PURPOSE:To accurately set up a compensating current value and to reduce the compensating current value without increasing a chip area by constituting an auxiliary D/A conversion part for compensating a conversion error of a ladder-type resistor and a constant current source. CONSTITUTION:A 6-bit digital signal is inputted, a 4-bit signal is outputted from a storage circuit and inputted as a control signal for the 2nd switch cell group 77 constituted of switch cells 19 to 22 in the auxiliary D/A conversion part 54 for compensating an analog output. When respective switches 19 to 22 in the cell group 77 are turned to left, a current is drawn from a power supply terminal 32 through resistor circuits 74, 75 and a potential difference appears on a resistor 23 to compensate an analog output from an analog output terminal 33. When only the switch cell 19 is turned to left, the synthetic resistance value of a ladder type resistor connection between the circuits 74, 75 is allowed to flow into a resistor 23 similarly to the left turn of the switch cell 17. Consequently the conversion precision of a D/A converter adopting a D/A conversion system consisting of a ladder type resistor and a constant current source can be improved.

Abstract: PURPOSE:To prevent a material from being judged as acceptable even when its flaw has not been sensed yet and to guarantee a quality with high reliability by a method wherein the noise level of a flaw detection signal generated during a flaw-detection inspection is compared with a reference monitoring-signal level which has been set arbitrarily.

When the probe unit 12 is separated and levitated from the round steel bar due to any problem in the arm, the spring and the like for the probe unit 12, a flaw-detection analog voltage signal 28 becomes nearly zero. Then, a flaw-undetected-state detection apparatus 32 which detects the levitation of the probe unit 12 so as to sense an undetected state of a flaw is installed, the levitation of the probe unit 12 and the cutoff state of a signal line 22 can be always monitored during a flaw detection, and a problem that even a material whose flaw has not been sensed is judged to be a good material is solved.
