Title: Potential measuring device
Inventor: TODOKORO HIDEO
IPC: G01N23/225
Filed: 1979-05-28
Abstract: PURPOSE: To increase the measuring accuracy by distributing properly the grid means, the secondary electron detecting means, the current detecting means and the division amplifying means each.  
     CONSTITUTION: Electron beam 11 is irradiated to the optional point on sample 4 via deflecting plate 1. Secondary electron 13 discharged from sample 4 is absorbed by 1st grid 2. Those which feature the low energy among secondary elecctrons 14 passed through grid 2 are reflected by the reverse voltage of the voltage applied to 2nd grid 3. Secondary electron 12 passed through grid 3 is detected by secondary electron detector 8. On the other hand, the voltage is applied to grid 2, and at the same time the current flowing through grid 2 is detected by detector 15. Both the output of detector 8 and the output of high-sensitivity ammeter 15 are led to division amplifier 16, and then the ratio between the both outputs is delivered. And this output is supplied to recorder 10 and the like.

IPC: H04N5/95
Filed: 1989-03-17
Abstract: PURPOSE:To contract the size of a circuit by providing a processing circuit with an image memory having two or more reading ports capable of reading out data asynchronously with writing and generating a delay for one line or plural lines selectively between two reading ports correspondingly to an operation state. CONSTITUTION:The processing circuit is provided with the image memory 8 having two or more reading ports capable of reading data asynchronously with writing and a delay value for one line or plural lines is selectively generated by changing reading control between two reading ports of the image memory 8 by two operation modes. Thereby, a signal processing circuit such as a subsampling coder requiring a line delay element can be selectively driven. In the mode for validating the operation of a noise reducer 3, the delay is not generated and data fed back from one reading port to the noise reducer 3 are synchronized with the input data. Consequently, the need for independently forming a line delay element can be eliminated and the circuit size can be reduced.

Title: Character recognizing device
Inventor: DOUKAWA YOSHIHIRO
IPC: G06K9/34
Filed: 1993-03-25
Abstract: PURPOSE:To provide a character recognizing device which can improve its recognizing performance even to the tilted characters. CONSTITUTION:The gray image signals of the character string supplied from a camera 1 undergo the A/D conversion through an A/D converter 2 and then converted into a binary image by a binarizing circuit 3. A character area detecting circuit 4 labels the areas and detects these labeled areas as a character string to be recognized. A tilt calculating circuit 5 detects the least coordinates in the Y direction of each character string label and calculates a regression straight line from each detected point. A character segmenting circuit 6 generates a rectangular area of the outermost shape of each character label by the regression straight line and the lines horizontal and vertical to the regression straight line. Then the characters are segmented based on the rectangular area and recognized by a character recognizing circuit 7. Thus it is possible to detect the tilting angle of the character string to segment the characters in response to the tilting angle and to improve the character recognizing performance.
