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.

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.

Control is performed for each of the individual components in accordance with a table including information on clock control and power control of each component of an information processing apparatus. Clock supply is stopped or clock frequency is lowered immediately or after the lapse of a predetermined period of time since the component is brought into an unused condition. Supply of power is stopped immediately or after the lapse of a predetermined period of time. In this case, the predetermined period of time can be automatically adjusted by detecting the condition of access to the component.

A laser butt welding apparatus including a pair of clamp elements at least one of which is movable reciprocally along the steel strip-feed line direction and which are adapted to clamp the edge portions of preceding and trailing steel strips, a shear which is advanceable and retractable between the pair of the clamp elements in a perpendicular direction to the line and cuts the edge portions of the preceding and trailing steel strips, structure for butting the cut faces of the preceding and trailing steel strips while being clamped by means of the clamp elements, and a laser torch adapted to condense a laser beam from a laser oscillator on an off-line at a weld zone and movable in a width direction of the steel strips to be welded together.
