    摘要: A signal processing portion obtains the reciprocal of a composite impedance of gap static capacitance and a plasma impedance, obtains composite static capacitance which is the sum of the gap static capacitance and a static capacitance component included in the plasma impedance from an imaginary part of the reciprocal, and obtains a resistance component included in the plasma impedance from a real part of the reciprocal. A gap detection device obtains the static capacitance component by using a model representing the characteristics of the reciprocal of the plasma impedance and the resistance component and obtains the gap static capacitance by subtracting the static capacitance component from the composite static capacitance. The gap detection device obtains a gap from the obtained gap static capacitance. Thus provided is a technique to detect a gap between a nozzle of a laser beam machine for outputting a laser beam and an object to be machined with high accuracy.

    摘要: A drive joint mechanism includes a drive shaft (30) and a driven shaft (24) coupled coaxially to the drive shaft (30). A coupling (31) on the drive shaft (30) or the driven shaft (24) has pin-engaging grooves (31a, 31b) and at least one pyramid-shaped pin-guide (32) between adjacent pin-engaging grooves (31a, 31b). An engagement pin (25) is provided on the other of the drive shaft (30) and the driven shaft (24) and engages the pin-engaging groove (31a, 31b). The engagement pin (25) contacts the pin-guide (32) while coupling the drive shaft (30) and the driven shaft (24). Thus, at least one of the drive shaft (30) and the driven shaft (24) is rotated by a pressing force exerted in the axial direction by the driven shaft (24) so that the pin-guide (32) guides the engagement pin (25) into the pin-engaging groove (31a, 31b).

    摘要: A one-way coupling transmits torque between a power-transferring spring clutch of a driving system, and a driven system. The coupling comprises a first coupler linked to the spring clutch, and a second coupler connected to the driven system. The power-transmitting direction of the driving system is the direction of spring clutch engagement, and is the rotational direction in which the couplers engage. The first coupler receives torque applied to the driven-system side of the coupling independently of the driving system only when the torque is in the rotational direction engaging the second coupler to the first, which at the same time is in the rotational direction in which the first coupler disengages the spring clutch. Torque on the driven-system side of the coupling in the opposite rotational direction disengages the coupling itself. The coupling is applied to the main driven axle of the positioning mechanism of a copying machine image transfer drum. When the drum is manually withdrawn, the second coupler is turned out of engagement with the first; whereas when the transfer drum is installed, the second coupler turns into coupling engagement with the first, but this twisting on the driving system link via the first coupler disengages the spring clutch. Consequently, when performing the manual mount/dismount operations, the driving system is not engaged, such that no hindering load is brought to bear the driven system side.
