Patent JP-S6113829-A (JP)
Title: Optical reception circuit
Inventor: EMURA KATSUMI
IPC: H04B10/2507
Filed: 1984-06-29
Abstract: PURPOSE:To always obtain a nearly flat frequency characteristic by operating an AGC circuit and also controlling an applied voltage to a varactor element to a proper value even when a front end circuit comprising an avalanche photodiode (APD) added with the AGC circuit and a high input impedance circuit. CONSTITUTION:An incident signal light 1 of a specific wavelength modulated by a pulse signal of a specific value is converted into an electric signal by an APD2 and becomes an output signal 22 after passing through a coupling capacitor 13, a high input impedance circuit 20 and an equalizing circuit 21. A part of an output signal 22 is extracted as a monitor use and peak detection is applied by a detection circuit 29. Then a peak detection output and an output of a reference voltage generator 23 are compared by a differential amplifier 24 to obtain an error signal 25. An APD bias circuit 26 is controlled by the error signal 25 to change the APD bias voltage 27 thereby changing the multiplier rate of the APD2, resulting that the control is applied to keep the output signal 22 always to a constant level. Since the characteristic of the equalizing circuit 21 is changed in response to the change in the band characteristic of the front end circuit in this case, the error signal 25 controls simultaneously a varactor element bias circuit 28 to adjust the band characteristic of the equalizing circuit 21.

IPC: G10L15/06
Filed: 1984-06-29
Abstract: PURPOSE:To adapt a standard pattern, by using a category name having the highest similarity as a recognized result and, when an error is detected in the recognized result, correcting the standard pattern of a category having the second similarity value by means of an inputted pattern. CONSTITUTION:In a standard pattern storing section 40 the standard patterns B<1>, B<2>,...B<n> of each word (n) are previously stored. An inputted pattern signal (u') is sent to a matching section 50 and the similarity value between the signal (u') and each standard pattern B<n> is calculated. Then distances D(n) between the segments of the signal (u') and corresponding segments of the standard pattern B<n> are respectively calculated and sent to a decision section as signals (d). The decision section 60 determines the first candidate word name n=r whose distance D(n) is the minimum and the second candidate word n=q. When the character being displayed in a display section 90 is wrong, a correction command (m) is issued through a correction key 80 and the second candidate character n=q is sent to the standard pattern storing section 40 as a signal (q').

Abstract: PURPOSE:To simplify the hardware structure of a printer by detecting the end of a mounted ink ribbon by the absence of the optical detection of an optical detecting means in case of using a color ink ribbon and by the presence of the optical detection of the means in case of using a black ink ribbon. CONSTITUTION:A color ink cassette and a black ink cassette are discriminated by intermittently operating a switch according to the configuration of a film ribbon cassette. In case of the color cassette, a signal from an output terminal S is discriminated, and if it is of a H signal, it is judged to be printable. If it is of a L signal, since the ribbon is of black line part, the ribbon is fed for several steps. The signal from the terminal S is again discriminated. In this case, if it is of a H signal, the width of the black line is narrow, and it is judged to be Y head. If it is of a L signal, since the width of the black line is wide, it is judged to be of film end. If it is judged to be the black cassette, a signal from the terminal S is discriminated, while if it is of the L signal, it is judged that it is printable on a black part. If it is of the H signal, it is judged to be of the film end.
