    摘要: A moving object detection system is provided with an existence detection part, an integrating part and an existence judgment part. Based on first and second detection signals, the existence detection part calculates a rotation angle of each transition factor that is obtained from the first and second detection signals and rotates around the origin in a two-dimensional coordinate system. The existence detection part is configured so that the rotation angle becomes less than 90 degrees. The integrating part integrates each rotation angle to obtain an integrated angle. The existence judgment part judges whether or not a moving object approaching or leaving a receiver of the device exists in a detection area based on the integrated angle and a threshold angle.

    摘要: A moving object detection apparatus comprises a transmitter, a receiver, a detection portion, a binary conversion portion and a judgment portion. The transmitter emits energy waves with a first frequency to a detection area. When receiving incoming energy waves from the detection area, the receiver generates an electric signal corresponding to the incoming energy waves. The detection portion obtains a detection signal from a reference signal with the first frequency and the electric signal. The binary conversion portion compares the detection signal with a conversion threshold signal to obtain a binary signal. The judgment portion judges whether or not a moving object approaching or leaving the receiver exists in the detection area based on the binary signal.

The system includes a first optical fiber directing the laser beam therethrough, and a pair of second optical fibers leading to the welding stations, respectively. A switching device connects the first optical fiber selectively to one of the second optical fibers so as to pass the laser beam to the corresponding welding station for enabling the laser welding thereat. The switching device comprises a housing having a longitudinal axis and holding input ends of the second optical fibers in parallel relation with the longitudinal axis, a carrier supporting an output end of the first optical fiber and linearly movable together therewith within the housing in a direction perpendicular to the longitudinal axis such that the output end of the first optical fiber comes into and out of closely end-to-end facing relation to the input ends of the second optical fibers. An electromagnetic relay is included to have an armature which is movable between two positions and operatively connected to move the carrier for aligning the output end of the first optical fiber to the input end of a selected one of the second optical fibers for passing the laser beam to the selected one of the second optical fibers. The output and input ends of the optical fibers are each provided on with a heat-radiating sleeve for dissipation of heat.

    摘要: An electrostatic relay essentially comprises a fixed electrode with a fixed contact insulated therefrom, a movable electrode plate with a movable contact insulated therefrom, and a fixed pair of oppositely charged electrets. The movable electrode plate is pivotally supported at a pivot in a cantilever fashion or a seesaw fashion, and also to move about the pivot axis relative to the fixed electrode between two rest positions of closing and opening the contacts. A control voltage source is connected across the fixed electrode and the movable electrode plate to generate a potential difference therebetween. The electrets are disposed adjacent the movable electrode plate to generate electrostatic forces attracting and repelling the movable electrode plate, respectively, when the movable electrode plate is charged to a given polarity. That is, the attracting and repelling forces are cooperative to produce a torque for moving the movable electrode plate in one direction from one of the rest positions to the other. The electrostatic relay is useful for precisely and rapidly operating the relay.
