Title: Character read system
Inventor: OOTSU KENJI
IPC: G06K9/62
Filed: 1979-07-20
Abstract: PURPOSE: To improve read precision without reference to the state of a character by setting three slice levels, by calculating the circumferential length of a character pattern and the area of a character part, and then by checking and deciding the propriety of the character.  
     CONSTITUTION: Pattern information obtained by scanning and photoelectric conversion by photoelectric conversion part B is digitized by three slice levels and stored in memory C. Binary-coding part D selects one of slice levels and converts it into a binary signal. On the basis of this binary-coded signal, calculation part E calculates the circumferential length of a pattern and the area of a character part. Character decision part F and final decision part G select the center slice level of the character pattern and perform character recognition processing on the basis of the binary-coded information. Next, a check on whether the ratio of area to circumferential length of the decided character is within a predetermined adequate range is made; when it is within the range, the above-mentioned result is regarded as the final decision result and when not, slice levels are changed to make a decision again. Thus, even when the character is binary-coded darkly or lightly, the accurate decision can be made lastly.

Title: Voltage comparator
Inventor: HOSHINO YOSHIKUNI
IPC: H03K5/02
Filed: 1986-04-22
Abstract: PURPOSE:To easily obtain a highly accurate fine comparing reference voltage without using a specific reference voltage generating circuit by changing the operating current of an input transistors (TRs). CONSTITUTION:Since the load TRs Q3, Q4 of an input stage constitute a current mirror circuit, the collector current of the TR Q3 is equal to that of the TR Q4 and the current of I1/2 flows into respective collectors. The relation of I2, I1 to be the operating current sources of the input TRs Q1, Q2 is set up to I3=nI2 (n is a proportional magnifcation). Since the operating current values of the TRs Q1, Q2 are different each other, a difference is generated between the base potential values of TRs Q6, Q7 even if there is no input signal to the voltage comparator. The difference is equal to the voltage difference between the base and emitter of the TRs Q1, Q2 and becomes the input offset voltage of the voltage comparator.

Title: Multi-port memory
Inventor: ONO KAZUKI
IPC: G11C11/41
Filed: 1989-04-12
Abstract: PURPOSE:To simplify the operation of a multi-port memory and to increase the processing speed by shifting successively the data held by the FF circuits corresponding to each column line of a memory cell array by the designated frequency and transferring only the data where the mask designating signal is set in a selection state to the memory cell array. CONSTITUTION:When a row address is designated, the data on the memory cells 11A - 11C connected to the same row line 13 are transferred to the transfer gates 3A - 3C through the column lines 12A - 12C. Under such conditions, the mask designating signals MD1 - MD3 are all set in a selection state via a mask register 4 and the gates 3A - 3C open to transfer the data to a data shift register 2. Then the data are shifted by the designated frequency via a shift value designating register 5. Hereafter only the data set in a selection state is sent to a memory cell array 1 among the signals MD1 - MD3. Thus the picture data can be partly shifted and the operation is simplified for a multi-port memory together with its processing speed.
