摘要： A rocking actuator and a laser machining apparatus which can suppress a temperature rise of a permanent magnet in a moving-magnet actuator. Even when a steerable mirror is positioned by rapid and continuous motions, highly reliable machining can be performed without degrading machining throughput or hole position accuracy. A cooling jacket for cooling a casing and heat transfer units brought into contact with a coil and the casing are provided. Heat generated in the coil is introduced to the casing through the heat transfer bypass units. Thus, the temperature rise of the coil is suppressed. Radial grooves are provided in the permanent magnet opposed to the coil so as to prevent an eddy current from appearing therein. Groove depth is made not smaller than skin depth expressed by a function of volume resistivity and permeability of the permanent magnet and a fundamental frequency of a current applied to the coil.

摘要： A scanner system includes a servo control unit. A rotation angle of a rotating shaft supporting a mirror is detected, and an error of the detected value with respect to a commanded value is integrated by an integral compensator so that the detected value is able to track the commanded value. A tracking error proportional compensator is disposed in parallel with the integral compensator so as to add a correction value proportional to the error to the integrated value of the error. A plurality of gains are prepared for each of the integral compensator, the tracking error proportional compensator, a detected value proportional compensator and a detected value differential compensator of the servo control unit. Each gain is changed in accordance with a travel angle of the commanded value. Thus, the mirror can be positioned quickly so that the machining speed can be improved.

摘要： A optical scanner control method and a optical scanner capable of positioning a mirror at a high speed independently of a rocking angle, and a laser machining apparatus for irradiating a printed circuit board with a laser beam by use of the optical scanner to thereby perforate the printed circuit board. In order to operate an actuator for rocking the mirror based on a deviation of a current position from an commanded value, a change in gain of the actuator is measured in accordance with each rocking angle in advance, and the manipulated variable of the actuator is corrected to cancel the change in gain. Thus, the influence of the alteration of a torque constant in accordance with the rocking angle can be suppressed so that the response characteristic becomes uniform all over a scanning region, and the positioning speed can be improved.

摘要： In a case where a position command path for a control position of a load 5 that is equivalent to a moving object is set by issuing a position command Rc(z), a gain for one of a high-frequency component, a specified frequency, and a specified frequency width is constrained. This means that a resonant frequency can be constrained, and that after the position command Rc(z) arrives at a target position, a position detection signal Y(z) can also arrive at the target position in a set number of steps. It is therefore possible to perform positioning at high speed and with high precision by constraining a resonance mode of a mechanism that includes the moving object, and a feed-forward control can be performed that meets target positioning times that are set for various types of operating patterns.

摘要： There is a need to provide a high-frequency power amplifier capable of reducing a talk current and reducing a phase deviation in output. The high-frequency power amplifier includes differently sized first through fifth power amplification transistors and impedance matching circuits for example. The high-frequency power amplifier changes a signal path to be used in accordance with a power specification signal. The high-frequency power amplifier uses a signal path from the first transistor to the second transistor in high power mode. The high-frequency power amplifier uses a signal path from the first transistor to the third transistor in medium power mode. The high-frequency power amplifier uses a signal path from the fourth transistor to the fifth transistor in low power mode. The high-frequency power amplifier is configured so that each of the signal paths includes the same number of stages of power amplification transistors and impedance matching circuits.

摘要： A reduction is achieved in the primary-side input impedance of a transformer (voltage transformer) as an output matching circuit without involving a reduction in Q-factor. An RF power amplifier includes transistors, and a transformer as the output matching circuit. The transformer has a primary coil and a secondary coil which are magnetically coupled to each other. To the input terminals of the transistors, respective input signals are supplied. The primary coil is coupled to each of the output terminals of the transistors. From the secondary coil, an output signal is generated. The primary coil includes a first coil and a second coil which are coupled in parallel between the respective output terminals of the transistors, and each magnetically coupled to the secondary coil. By the parallel coupling of the first and second coils of the primary coil, the input impedance of the primary coil is reduced.
