    摘要: A cable detector has a plurality of rotatably series connected hooks having an opening mouth for accepting a cable on sea bottom with an equal angular intervals, a contact pressure sensing means for indicating that a cable is engaged with one of said hooks by measuring contact pressure on one of the hooks, and an electrical switch which is actuated by said contact pressure sensing means to provide an electrical signal when a cable is detected.

    摘要: A light emitting element failure detector (4) includes a light emitting element (1), a constant current circuit (2) which supplies an electric current to the light emitting element (1), and an electric discharge path which discharges an electric charge such as the light emitting element (1). A light emitting element failure detector (4) further includes an instantaneous current interruption circuit (5) which instantaneously interrupts an electric current to the light emitting element (1) by a current supply path different from the electric discharge path, a diode (60), a DC power supply (61), and a current detector (62). The DC power supply (61) generates a direct-current reference voltage having a positive value lower than a voltage between the anode and cathode of the light emitting element (1) in a normal state. The DC power supply (61), the diode (60), and the current detector (62) which are connected in series constitute a parallel electric path of the light emitting element (1). An anode of the DC power supply (61) and a cathode of the diode (60) are arranged on the anode side of the light emitting element (1). The current detector (62) detects an electric current which flows in the parallel electric path when an electric current is instantaneously interrupted.
