Title: Key telephone system
Inventor: KATO TATSUYA
IPC: H04Q3/58
Filed: 1980-10-13
Abstract: PURPOSE:To prevent the malfunction, by transmitting a connection fault diagnostic signal to respective key telephone sets periodically through a data line from a main device and by performing normal data receiving only when the connection completion signal from key telephone sets is normal. CONSTITUTION:A main device 10 and plural key telephone sets 20 are connected by two or more pairs of data lines for transmission and receiving and voice service lines, and a connection failt diagnostic signal is transmitted from a connection fault diagnostic circuit 15 of the main device periodically to respective key telephone sets. The connection completion signal transmitted from a receiving data processing circuit 24 in the key telephone set side is received by a receiving processing device 18 through a transmitting circuit 26; and if the connection completion receiving signal from the device 18 corresponds to the transmitted diagnostic signal, a normal connection is discriminated by the diagnostic circuit 15 to instruct the processing device 18 to perform the normal data processing. Thus, when line connections and telephone sets are abnormal, the operation of the processing device 18 is stopped by the diagnostic circuit 15 to stop the acceptance of data, thereby preventing the malfunction.

Filed: 1980-10-13
Abstract: PURPOSE: To know the number of unexposed frames at the begining, by obtaining the number of unexposed frames by counting the number of perforations by winding a film up to its end in engagement with the closure of back cover.  
     CONSTITUTION: On the closure of a back cover, a back-cover coupling switch SW1 turns on to reset a perforation counter PC and a frame-number counter FFC by a differential pulse from a synchronous differentiating circuit SDC1, and a transistor TR1 turns on by the H output of a flip-flop FF1 to turn a motor M as shown by an arrow (a), thereby starting an film advance. As a perforation detection switch SW2 turns on intermittently, the perforation counter counts the number of the turn-on operations and the frame-number counter counts the number of pulses each generated each time the perforation counter goes up to a prescribed number. When the film is advanced up to the end, the output of a film end detecting circuit FED stops the turning of the motor.

IPC: G03F1/84
Filed: 1986-06-19
Abstract: PURPOSE:To realize easy and reliable detection of defects even in an extremely fine pattern, by forming a defect detecting pattern having the same configuration as a predetermined pattern in the peripheral space of a photomask and exposing it with an amount of light lower than an appropriate exposure. CONSTITUTION:Predetermined patterns 2 are formed lengthwise and crosswise in the central portion of the principal face of a mask substrate 1 for forming a circuit functioning element. A defect detecting pattern 3 is formed in the peripheral space of the principal face of the substrate at a distance from the group of the predetermined patterns 2. The defect detecting pattern 3 is formed in the following manner: first, an original pattern formed in a reticle is exposed by the step-and-repeat technique to form the group of the predetermined patterns 2, and then the same pattern as the predetermined pattern 2 is exposed with an amount of light corresponding to about 0.8 times as large as the exposure of the predetermined pattern 2. The size of the defect detecting pattern 3 thus formed is generally decreased in comparison with that of the predetermined pattern 2, while a defective portion 13 in a bridge is formed in an enlarged and exaggerated manner. Accordingly, provision of such defect detecting pattern 3 enables any defect in the pattern to be detected reliably even with a conventional detecting apparatus.
