Title: Character segmenting system
Inventor: GOTO SHIGERU
IPC: G06K9/34
Filed: 1985-11-22
Abstract: PURPOSE:To improve precision with a simple constitution by repeating a redivision process until the segmenting points of all of the division areas are decided, and deciding a character segmenting position based on the decided segmenting point of each division area and a division line in a horizontal direction. CONSTITUTION:A control circuit 312 switches a switching circuit 309 to a pattern histogram memory 308, and starts up a block detection circuit 311 regarding a detected sun spot histogram, then detecting a block. When the block is detected, the intermediate point of adjacent blocks is found, and it is set as the segmenting point. When plural segmenting points are detected in one division area, the segmenting point nearest to the center position of a character circumscribing frame in the horizontal direction is set as the segmenting point. When the segmenting points at an upper and a lower division areas are decided respectively, the segmenting position is decided with each segmenting point. After all of the segmenting points at the division areas have been detected, the character segmenting position is set with each segmenting point and the horizontal division line. Thus, since the character circumscribing frame is divided in the horizontal direction and the sun spot histogram is generated, and the segmenting position is decided at every division area, a character segmenting can be performed in a rapid process time.

Title: Directional comparison relaying device
Inventor: SADAGAMI TAKAMICHI
IPC: H02H3/26
Filed: 1987-10-20
Abstract: PURPOSE:To obtain a directional comparison relaying device, which enables an interrupting instruction to be speeded up, by changing the time cooperation in accordance with a level of fault current, when an internal accident occurs, and shortening the time cooperation in its length when the fault current is generated in a large level. CONSTITUTION:In occurrence of a internal accident, when an inflow detector DI operates in one terminal of an inflow end, an output e1 disappears in a NOR circuit 1, and a transmitter TS transmits continuous permission. Here a current detector OC generates a control output matched with a level of fault current, and a time delay operating circuit TE4 generates an output after the predetermined time suited for the level of the fault current. Similarly upon actuation of the inflow detector DI also in the other terminal, because the transmitter TS transmits the continuous permission, a receiver RC is placed in the continuous permission after the delay time of transmission. Consequently, an output e6 is generated from an AND circuit 6, and interruption is instructed by an output e5.
