Abstract: PURPOSE:To shorten the modifying time of a printed wiring board by extracting all remaining conductors after inputting a photographed circuit pattern to a labeling circuit and expanding and contracting the circuit pattern with a logical filter and extracting harmless remaining conductors. CONSTITUTION:The circuit pattern of a printed wiring board 1 photographed with a camera 10 is inputted to a labeling circuit 11 and logical filter 12 and the circuit 11 only extracts remaining conductors 4 and 5 which do not exist in a reference picture. Both sides of the circuit pattern inputted to the filter 12 are expanded by the half of an allowable creep distance specified by a standard. Then the remaining conductor 4 is connected with the expanded section of a conductor 2 at the expanded section, but, when the expanded section is contracted to the original width, the remaining conductor 4 becomes a remaining conductor which connects the upper and lower conductors 2. Then the pattern is inputted to a labeling circuit 13 and only the remaining conductor 5 is extracted and a deciding section 14 takes out the conductor 5 from the remaining conductors 4 and 5 extracted by the circuit 11 to extract only the conductor 4 which may short-circuit the conductors 2 with each other and does not match the standard. Therefore, the modifying time of the board 1 can be shortened.

Title: Power line data carrier system
Inventor: OMURA NOBUHIKO
IPC: H04B3/54
Filed: 1989-09-02
Abstract: PURPOSE:To prevent occurrence of crosstalk caused between two carrier frequencies by splitting one carrier frequency into two partial carrier frequencies, and superimposing the carriers whose frequency band differs from each other onto a commercial frequency voltage while being separated for each partial carrier frequency. CONSTITUTION:Carrier generating circuits 16a, 16b generate any carrier frequency above and below the center frequency in frequency bands Ba, Bb. Bit content of data to be carried from a processor side is supplied to the carrier to designate the carrier frequency and the carrier is superimposed on a commercial frequency signal on a power line L via an HPF coupler 18. Carrier detection circuits 17a, 17b receiving a carrier via the coupler 18 from the power line L conversely are brought into the operating state depending whether the frequency is within the first half of the partial carrier frequency or within the latter half. Since only the frequency carrier is singly received in the frequency band Ba or Bb during the operation, even when a filter circuit with a low Q is used for noise countermeasure, production of crosstalk between the carriers is prevented.
