Title: Character recognizing device
Inventor: HOTTA YOSHINOBU
IPC: G06K9/72
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To perform fast, high-precision character recognition without the influence of missegmentation even if characters are in contact with each other. SOLUTION: A word area specifying means 1 specifies a word area from image data by using key characters etc. The image data in the word area are normalized by a normalizing means 2 and features are extracted by a feature extracting means 3. A matching category limiting means 4, on the other hand, estimates the number of the characters in the word area and calculates the complexity to limit a matching category based on these results. A matching means 5 matches feature data of the extracted word area against feature data in a word feature dictionary 6 as to the object of matching limited by the matching category limiting means 4 and outputs the recognition result. When characters to be recognize represent an address etc., the object of matching can be further limited by making good use of previously recognized addresses of a higher layer.

Filed: 1987-05-25
Abstract: PURPOSE:To set the operating temp. of a superconducting memory as high as about the temp. of liquid nitrogen by preparing a thin superconducting film on a substrate and reading out memory contents by determination of 1 and 0 from whether a superconductor exists in a reading out site or not. CONSTITUTION:A photomask 1 which is formed with the patterns of light shielding parts 200 at 2mum length per piece of the patterns and 4mum intervals, shields light at the point corresponding to a bit '1' and allows the transmission of light at the point corresponding to a bit '0' is formed. A photoresist 2 and the thin superconducting film 3 are laminated on a substrate 4 and are subjected to pattern etching to form the resist patterns according to the contents of the memory on the surface of the thin superconducting film 3. The part where the superconducting microplane exists is read out as the bit '1' and the part where said plane does not exist is read out as the bit '0' when this track runs right under a head.

Title: Speed control system for dc motor
Inventor: IWAKI KUNIO
IPC: H02P7/28
Filed: 1982-07-23
Abstract: PURPOSE:To eliminate a digital-to-analog converter by converting the difference between the speed command signal of a DC motor and a speed detection voltage into a pulse time width containing the polarity in the step of converting the speed detection voltage into a pulse time width signal. CONSTITUTION:A waveform generator 1 outputs a triangular wave signal SG1 and outputs a rectangular wave pulse signal SG2. A digital unit 2 outputs a logic signal to terminals H1-H6 by the signal SG2. A double integration type analog unit 3 outputs a pulse time width signal including the polarity as the difference between the generated voltage ETG of a tachometer generator and an encoded speed command signal. A pulse modulator 4 converts it into a DC voltage which is proportional to the pulse time width of the pulse time width signal and outputs it to control terminals DR1-DR4. In this manner, the speed is controlled directly by a digital signal without a digital-to-analog converter.
