Title: Optical character reader
Inventor: SAWADA MINORU
IPC: G06V30/146
Filed: 1981-02-24
Abstract: PURPOSE:To increase a processing speed and to simplify a mechanism, by detecting whether a mark is entered in a specific area of a business form, selecting a dictionary memory to be used, and after that, reading a character. CONSTITUTION:When a mark area 1a of a business form 1 is opposed to a mark read sensor 6, voltage corresponding to the quantity of a reflected ray is outputted. This output voltage is amplified at 7, a mark is detected at 8, and a  switching signal of ''1'' or ''0'' is outputted. A switching circuit 9 makes the first  dictionary memory 10 or the second dictionary memory usable by the switching  signal. Subsequently, an optical sensor 2 reads a character area 1b of the business form 1, converts it to a digital signal by an A/D converter 3, and after that,  removes a noise and normalizes by executing a preprocessing 4, and a character  pattern is obtained. From this character pattern, a feature is extracted 5. A  comparing part 12 compares this extracted feature with contents of the dictionary memory 10 or 11 read out through the switching circuit 9, and decides a  character 11.

Title: Device and method for reproducing recorded information from magneto-optical recording medium
Inventor: KIM DAE YOUNG
IPC: G11B20/14
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To correctly detect a reproduced bit signal by sampling/holding a reproduced electric signal delayed by a reproducible delay time when a recording medium is irradiated with a pulsated reproducing beam and the reproduced electric signal is detected. SOLUTION: When a reference signal is detected, a slicer 101 of a reproduced clock generator 100 slices the reference signal to output it, and an edge detector 102 detects the edge of the sliced signal. A phase difference detector 103 detects a phase difference between the output signal of the edge detector 102 and the output signal of a frequency divider 106. A low-pass filter 104 filters a phase difference signal from the phase difference detector 103 to output it to a voltage control oscillator VCO 105. The VCO 105 outputs an oscillation signal as a regenerative clock signal, and the frequency divider 106 divides the oscillation signal by 1/M, and outputs it to the phase difference detector 103, and generates a delay signal answering to the detected phase difference to hold a delayed pulse signal in a sample-and-hold means.
