Title: Line type recognizing method for automatic drawing input device
Inventor: SEKIGUCHI NAGISA
IPC: G06F17/50
Filed: 1990-11-22
Abstract: PURPOSE:To prevent erroneous recognition when identifying a character or the one part and a broken line/chain line by identifying a broken line/chain line candidate and the other candidate from the feature of a terminal point in a line segment candidate. CONSTITUTION:The vector group of the broken line/chain line candidate having the possibility of the broken line/chain line is separated from the vector group of the line segment candidate, and the path of a line is searched from the connection of this vector group so as to be separated into vector groups for each path. When the both ends constitute a closed loop (a) for each path or when any one of the ends becomes a branch (b) or a cross (c), the vector group of the path is recognized as the vector group constituting the broken line/chain line. Namely, by utilizing the fact that the path of the broken line/chain line becomes the closed loop (a) or that one end of the path becomes the branch (b) or the cross (c), the broken line/chain line candidate and the other candidate are identified from the feature of the terminal point of the path. Thus, the character or the one part thereof is not erroneously recognized as the broken line/chain line.

Title: Method for selecting receiving frequency in rds receiver
Inventor: RYU KOICHI
IPC: H04B1/16
Filed: 1987-12-17
Abstract: PURPOSE:To maintain an always stable receiving condition by, when a receiving frequency is switched to the other same network station frequency, making such a station frequency into the new receiving frequency at the time when the receiving signal level is at a setting level or above, and executing a check again in lowering the setting level at the time when the receiving signal level is at the setting level or below. CONSTITUTION:By the processor of a controller 14, the frequency (AF) data of a network station group supplied to a PLL circuit are set to a programmable frequency-divider in the PLL circuit. After the time-up of a PLL timer, the receiving signal level of a network station in the middle of receiving at present is fetched from a level detecting circuit 17, and when such a receiving signal level VS is at a first setting level VH or above, the network station frequency in the middle of receiving at present is made into the new receiving frequency. When that the receiving signal level VS is below the first setting level VH is decided, the AF data of a former receiving station are read. In the level check at a second time, the setting level is made into a second setting level VL lower than the first setting level VH. The receiving signal levels are checked to all network station frequencies.
