摘要： A high-frequency power supply apparatus includes the following elements. A first power supply outputs a first high-frequency voltage with a first fundamental frequency. A second power supply outputs a second high-frequency voltage with a second fundamental frequency lower than the first fundamental frequency. A second matching device is connected between the second power supply and the load. The second matching device generates a timing control signal with a frequency lower than the second fundamental frequency. The first power supply generates a modulation signal by applying a start phase and a frequency shift amount to a modulation fundamental wave signal whose frequency is equal to the second fundamental frequency. The start phase is applied to the modulation fundamental wave signal in accordance with an input timing of the timing control signal. The first power supply performs frequency modulation on the first high-frequency voltage by using the modulation signal.

摘要： Provided is a marker position registration device that can prevent an axial direction in a coordinate system from being erroneously registered when a position in a marker is to be registered. The marker position registration device includes a display control unit that causes an input form to be displayed, the input form allowing coordinates in a robot coordinate system corresponding to a specific portion of an industrial robot when the specific portion indicates a specific position in a marker to be input in association with a position identifier for specifying the specific position which is assigned to the marker and a registration unit that registers the specific position in the robot coordinate system on the basis of a content input to the input form.

摘要： Proposed are techniques for simplifying the process of suppressing an increase in a reflected wave Pr due to IMD. A high-frequency power supply system for providing high-frequency power to a load includes: a bias power supply for supplying a bias power having a first frequency; a source power supply for supplying a high-frequency output having a second frequency higher than the first frequency and being frequency modulated with the first frequency; and a matching device including an impedance matching circuit for acquiring the bias power and the frequency modulated high-frequency output and achieving impedance matching between the source power supply and the load. The source power supply, in response to a trigger signal for timing having the first frequency, detects a reflected wave while causing a modulation start phase and a modulation amount gain to be varied, and determines an optimum modulation start phase and modulation amount gain that minimize the reflected wave.

摘要： A high-frequency power supply apparatus includes the following elements. A first power supply supplies first power to a load by outputting a first voltage whose fundamental frequency is higher than a second voltage output by a second power supply. A period signal generation circuit generates a period signal matching a frequency and a phase of the second voltage. A waveform control circuit generates a modulation signal for performing frequency modulation on a fundamental wave signal of the first voltage, and adjusts an output timing of the modulation signal in accordance with a timing of the period signal. The first power supply generates a first frequency signal by performing frequency modulation on the fundamental wave signal of the first voltage by using the modulation signal. The first power supply performs power amplification on the first frequency signal and outputs, to the load, the first frequency signal as first power.

摘要： An aligner device includes a robot hand, a lifting mechanism, sensors, a misalignment calculating unit, an x-y misalignment correcting unit, and a θ misalignment correcting unit. The robot hand includes vertically aligned hand members each configured to hold a planar workpiece. The lifting mechanism moves planar workpieces transported by the robot hand up from and down to the hand members, respectively. Each of the sensors, vertically spaced apart from each other, has a downward sensor surface to capture the outline of a planar workpiece brought close to the sensor surface by the workpiece lifting mechanism. The misalignment calculating unit calculates, by using the images of the captured outline shapes of the planar workpieces, an amount of positional misalignment of each planar workpiece with a reference position in X, Y and θ directions. The X-Y misalignment correcting unit corrects the misalignment of each planar workpiece in the X and Y directions based on the amount of X-Y direction misalignment calculated by the misalignment calculating unit. The θ misalignment correcting unit corrects the misalignment of each planar workpiece in the θ direction based on the amount of θ misalignment of the planar workpiece.
