摘要： A detection unit (8) is disposed for detecting the magnitudes of f1 and f2 frequency components of a composite signal which is passed through a center electrode cable (4). A detecting signal generating unit (9) generates a detecting signal corresponding to a gap between a nozzle (5) and a workpiece (6) from the magnitudes of the f1 and f2 frequency components of the composite signal, which are detected by the detection unit (8). As a result, even if plasma occurs in the gap between the nozzle (5) and the workpiece (6), the gap can be detected with a high degree of precision.

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.

摘要翻译： 单向联轴器在驱动系统的动力传递弹簧离合器和驱动系统之间传递扭矩。 联接器包括连接到弹簧离合器的第一联接器和连接到被驱动系统的第二联接器。 驱动系统的动力传递方向是弹簧离合器接合的方向，并且是联接器接合的旋转方向。 第一联接器仅在扭矩与第二联接器接合的旋转方向上接收与驱动系统相关联的驱动系统侧的扭矩时，第一联接器同时处于旋转方向 第一联接器脱离弹簧离合器。 联轴器的驱动系统侧的扭矩在相反的旋转方向上脱离联轴器本身。 联轴器应用于复印机图像转印鼓的定位机构的主从动轴。 当滚筒被手动取出时，第二联接器与第一连接器脱离接合; 而当安装转印鼓时，第二耦合器变成与第一耦合接合，但是通过第一耦合器在驱动系统链​​路上的这种扭转使得弹簧离合器脱离。 因此，当进行手动安装/卸载操作时，驱动系统不被接合，使得不会承受受驱系统侧的阻碍负载。
