摘要： Are disclosed a method of detecting a hold-position of an electronic component in which the component is held by an electronic-component holding apparatus, an electronic-component holding apparatus having a hold-position detecting device, and an electronic-component mounting apparatus for mounting an electronic component on a printed-circuit board. The above method includes the steps of emitting light beams in a direction toward the electronic component (W) held by the electronic-component holding apparatus (58, 70), so as to take a projection of the component, and of detecting a position of the projection, thereby detecting the hold-position of the component. The above holding apparatus is characterized in that at least a part of a holding head body (86) which surrounds a center line of a sucking pipe (88) is made of a transparent material, and in that the holding apparatus has the hold-position detecting device which includes a light emitter (146) for emitting light beams in a direction parallel to the center line of the sucking pipe so as to take a projection of the component held by the sucking pipe, and further includes an electronic image device (150) for detecting a position of the projection. The above mounting apparatus has at least one holding head (70) which is stopped at a pair of intervening stops between a receive-stop at which the head receives the component and a mount-stop at which the head mounts the component on the board, at one of the intervening stops the hold-position of the component being detected, at the other intervening stop an incorrect hold-position of the component being adjusted.

摘要： An output voltage regulator for an engine-driven generator that can satisfactory suppress fluctuation in output voltage, even when an output waveform of the generator is distorted. An engine revolution period that represents a period of output voltage is detected by use of an ignition signal. Data that represents an output waveform is obtained by squaring and adding up an instantaneous value of the output voltage for one period of engine revolution. Furthermore, a square root of the data is extracted as an effective value. An operation duty of a transistor Q1 provided in an output circuit of an excitation winding L2 that supplies a field current “if” is determined based on a difference between the effective value and a target voltage. The field current “if” changes according to the difference, and the output voltage is thereby regulated according to a load.

摘要： A power unit is provided which can perform stable feedback control by reducing a feedback gain, and sufficiently cope with fluctuations in the output voltage occurring according to fluctuations in the input voltage caused by fluctuations in the rotational speed of an engine. A pair of variable control bridge circuits are connected to three-phase output windings of a three-phase generator driven by the engine, and connected in an antiparallel manner to each other to form a cycloconverter for generating a single-phase alternating current to be supplied to a load. An effective voltage value-detecting circuits detects an effective value of a voltage of the alternating current. A reference effective voltage value-generating circuit generates a reference effective voltage for controlling the single-phase alternating current. A target wave-forming circuit forms a target wave for making the effective value of the voltage closer to a value of the reference effective voltage. A firing angle control device performs switching control of the variable control bridge circuits, based on the target wave, such that the variable control bridge circuits are alternately switched to operate every half a repetition period of the alternating current. A rotational fluctuation-detecting circuit detects fluctuations in a rotational speed of the engine in a rotation cycle thereof. A gain-adjusting circuit generates a reverse characteristic signal having a characteristic reverse to a characteristic of the fluctuations in the rotational speed of the engine. A comparator corrects amplitude of the target wave based on the reverse characteristic signal.
