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.

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.

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 relay driving circuit for a latch-in type magnetic relay having an excitation coil, generating a set current and a reset current of opposite polarity for the coil. A capacitor is provided between the input terminals of the circuit in series with the coil. A set switch is connected in series with the coil and the capacitor, and a reset switch is connected across the series combination. An input voltage level detector is provided to make the set switch conductive, thereby applying the input voltage to the excitation coil and the capacitor to provide the set current. As the input voltage decreases below the trigger level, the detector makes the reset switch conductive to allow the capacitor to discharge current in the opposite direction through the excitation coil. The circuit includes a disable switch responsive to the capacitor being charged to a voltage level sufficient to provide the reset current, the disable switch setting the set switch to a non-conductive state to thereby prevent the capacitor voltage from being reversely applied.

摘要： An improved magnetic actuator mechanism suitable for dot printing mechanisms for use in a wire matrix dot printer. The present magnetic actuator mechanism comprises an armature movable between a reset position and an actuated position, a permanent magnet for attracting the armature toward the reset position, and an electromagnet which, when energized, generates in the armature a magnetic flux opposite to and larger than the magnetic flux generated therein by the permanent magnet. The armature is thus moved to the actuated position by the turn of the magnetization direction in the armature when the electromagnet is energized. Therefore, in the present invention, the armature can have the magnetic fluxes in the opposite directions by the action of the permanent magnet and electromagnet combination so as to provide the armature of smaller cross sectional area or thickness with a higher magnetic force without causing the magnetic saturation thereof, which allows the use of an armature of less thickness or weight to assure high speed operation in response to a driving signal.
