摘要： PROBLEM TO BE SOLVED: To provide an optical monitor device which can securely monitor the presence of absence of an optical signal and its transmitting direction. SOLUTION: Most part of the optical signals transmitted by an optical fiber 14a are outputted to an optical fiber 14b through a branching film 15. A part of the optical signals, which is reflected from the branching film 15, is detected by a PD(photodiode) 21a. A part of the optical signals, which is scattered t the back of the branching film 15, is detected by a PD 21b. The level difference of the detection levels of the PD 21a and the PD 21b is obtained in a differential amplifier. When the level difference exceeds a reference value, the valid optical signal is judged to be detected in the PD 21a with the higher level and an LED(light emitting diode) 18a is lighted.

摘要： PROBLEM TO BE SOLVED: To provide a circuit breaker capable of being closed from remote position by using a remote controller. SOLUTION: In a normal condition, a circuit breaker 10 is closed and a NiCd battery 30 is fully charged with a direct-current voltage of 24V generated by a power supply part 20. When the circuit breaker 10 is disconnected, a detection part 40 is irradiated with infrared rays IR from a remote position by using a remote controller. A current flowing through a photodiode 42 is changed by the infrared rays IR and a detection circuit 43 detects the change in the current and outputs a detection signal DET to a drive part 50. On receiving the detection signal DET, the drive part 50 outputs drive power DRV for a fixed time for closing a contact 13 of the circuit breaker 10. A lever 15c is attracted by a solenoid coil 16, the contact 13 is closed, and thus the breaker is restored.
