Title: Detector for center position of circular graphic form
Inventor: SAKURAI YOSHIKI
IPC: G06T7/60
Filed: 1987-11-09
Abstract: PURPOSE:To improve the detecting accuracy of a center by searching all pairs in which a coordinate difference between two picture elements on an edge part coincides with a value stored in a difference table memory and searching a maximum value in a center histogram memory in each set diameter range. CONSTITUTION:An edge image memory 1 inputs a video signal (a), converts the input signal into an image obtained by extracting only by the edge part of a graphic form and stores the converted image. A diameter detecting circuit 3 successively reads out difference data (b) in the diameter rang set in a difference table memory 2 in which data are previously set and compares the read data with the difference between the picture elements on the edge part set up in the memory 1. Then, the pairs (c) of the picture element coordinates data coincident with the difference data are sent to a center histogram memory 4 and frequency data to be the center position of the data pairs (c) in respective coordinate value are counted up. A center coordinate detecting circuit 5 outputs the coordinate value whose frequency value is maximum as the center position of the image. Even if large noise exists, the center position of a circle can be highly accurately detected.

Title: Input system for kana/kanji conversion
Inventor: SAGARA KATSUSHIGE
IPC: G06F17/22
Filed: 1986-11-28
Abstract: PURPOSE:To increase the repetitive input speed of characters and at the same time to reduce the fatigue of an operator by designating a storing place to store the Japanese rendering and KANJI (Chinese characters) into a memory circuit when both Japanese rendering and KANJI are fixed and hereafter reproducing these rendering and KANJI with input of a corresponding key for decision and extraction and a place designation key. CONSTITUTION:The Japanese rendering and KANJI are first fixed and the relevant fixing key and storing key are pushed. Thus a storing place is designated by an optional key set at an alphabet position on a keyboard 10. Thus a fixed KANJI string is stored in a designated relative storing place of a fixed KANJI string memory circuit 20 after the information is obtained by a fixed KANJI string output circuit 16. Then a stored key is designated for designation of a fetching place when a fixing/extracting key is pushed. Thus the fixed KANJI string stored in the designated relative storing place of the circuit 20 is informed to the circuit 16. Then the fixed KANJI string is delivered as long as its output is possible. Thus it is not required to have repetitive inputs of the same Japanese rendering.

Filed: 1993-11-12
Abstract: PURPOSE:To obtain a double speed search picture with high quality by comparing a comparator output with a comparator output delayed by one field and controlling a reference voltage of a comparator so that both the outputs are not overlapped with each other. CONSTITUTION:An overlap detection circuit 10 detects overlap between envelope signals Ea, Eb by detecting an overlap of output signals Ca, Cb of a comparator 8.

Thus, transistors (TRs) 11d, 11e are turned off and the reference voltage Vref obtained by dividing a DC voltage Vcc by resistors 11a, 11b is unchanged. When the voltages Povr and Vref are dissident, the circuit 10 and the reference voltage generating circuit 11 turn on one of the TRs 11s, 11e to bypass the resistor so as to make the voltage Povr coincident with the voltage Vref.
