Title: Faulty location system for optical fiber
Inventor: KINUGASA NORIO
IPC: G01M11/00
Filed: 1985-07-23
Abstract: PURPOSE:To spot an optical fault point with high precision as to a relatively long line and a line including an intermediate relay by transmitting a signal to which transmission time information is added through a couple of optical fibers in both directions, and calculating the optical fiber fault point from the difference in the casing time of a received signal between reception sides. CONSTITUTION:The signal to which the transmission time information is added is transmitted between stations 1 and 2 which are at distance L in both directions through the couple of optical fibers 3-1 and 3-2. The distance (x) from the station 1 to the fault point 4 is calculated from equation I on the basis of time points TA and TB of the ceasing of the received signal at the stations 1 and 2 and the optical fiber fault point is spotted with high precision for a relatively long-distance optical fiber and a line including a relay. In the equation, Vg is the propagation speed of a signal in an optical fiber.

Filed: 1980-11-17
Abstract: PURPOSE:To prevent an issuing error due to negligence of changeover of a line switch, by detecting a make and break state of a door switch and a changeover state of the line switch by interlocking them, in a terminal ticket issuing machine connected on-line with a processing device. CONSTITUTION:A ticket issuing machine 1 is provided with a ticket issuing part 5 for printing on a ticket and outputting it, changeover switches S2, S3 for switching the on-line and the off-line, and a ticket issuing button 2, and is connected to a processing device 9 for totaling a casting data, through a circuit 8. Contact signals of a door switch S1 and a switch S2 which have been installed to the door of the ticket issuing machine 1 control the ticket issuing part through inhibiting gates 4, 3. According to such a constitution, when the contact signal of the switch S2 is ''0'', that is to say, off-line, and the contact signal of the switch S1 is ''1'', an output signal of the gate 4 inhibits a ticket issuing signal A generated from the gate 3. Accordingly, when the door remains closed in an off-line state, no ticket is issued even if the button 2 is pushed, therefore, an issuing error is prevented.
