摘要： A winding of a motor is formed by coiling a wire around a slotless stator core with combination of troidal coiling and array coiling. The toroidal coiling is carried out in a manner such that the wire is coiled without any intersecting turns in one direction for the formation of the winding as it is coiled rotating spirally. By this coiling method, the accuracy of the position of the winding in the direction tangent to the surface of the stator core can be improved. The array coiling is carried out in a manner such that the winding is formed in layers that are stacked on one another. By this coiling method, the accuracy of the position of the winding in the direction normal to the surface of the stator core can be improved. Thus, the overall thickness of the winding can be made uniform.

摘要： A linear driving device of compact size capable of fundamentally canceling a reactive force produced in acceleration and deceleration of a slider within the linear driving device. A slider and a stator constitute a linear motor. The stator is supported to move linearly on the base by an air bearing and the slider is supported to move linearly on the stator. When the slider is driven by the stator to move in one axial direction, a reactive force is exerted on the stator in an opposite axial direction to move the stator in the opposite direction, so that substantially no force is transmitted from the stator to the base. A ratio of weights of the stator and the slider is lopsided so that motion strokes of these members are different. Since the reactive force produced in acceleration and deceleration is canceled within the linear driving device and is not transmitted to the base, any undesirable effect is caused outside of the linear driving device. This device can be applied to a machining tool or a measuring device to realize a high-speed and high-precision machining or measurement.
摘要翻译：一种紧凑尺寸的线性驱动装置，其能够基本上抵消在线性驱动装置内的滑块的加速和减速中产生的反作用力。滑块和定子构成线性马达。定子被支撑以在空气轴承上在基座上线性移动，并且滑块被支撑以在定子上线性移动。当滑块由定子驱动以在一个轴向上移动时，反作用力在相反的轴向方向上施加在定子上，以使定子沿相反方向移动，使得基本上没有力从定子传递到基座。定子和滑块的重量比不对准，使得这些构件的运动行程不同。由于加速和减速时产生的反作用力在线性驱动装置内被消除，并且不传递到基座，所以在线性驱动装置之外引起不期望的效果。该装置可应用于加工工具或测量装置，实现高速，高精度的加工或测量。

摘要： A pneumatic bearing motor with a pneumatic bearing capable of being downsized without lowering the mechanical rigidity thereof. A stator of the pneumatic bearing motor comprises a slot-less stator core and winding which is formed by winding a wire on the stator core into a toroidal shape in a maimer of regular winding. Since the stator does not have projections as exist in conventional stators, it is not necessary to form counterbores in a housing and make wall thickness of the housing large for bearing stress concentration caused by the counterbores. Thus, it is possible to reduce the wall thickness of the housing of the motor and downsize the motor.

摘要： A pulse generation means that generates a pulse each time an XY movable member moves linearly by a certain amount relative to a base is provided. A workpiece and a light and dark pattern member are provided on the base. A tool, a light and dark pattern scanning sensor that scans the light and dark pattern and outputs a scanning signal, and a cutting means that moves the tool with respect to the workpiece in a cutting depth direction, orthogonal to the linear motion direction, are provided on the XY movable member. While the XY movable member moves relative to the base, the tool is moved by the cutting means in accordance with a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and the pulse from the pulse generation means to perform machining.

摘要： A linear encoder comprises a light source, a main scale provided with a measuring pattern having a constant pitch, an index scale to which a measuring pattern having a constant pitch is mounted, and a light receiving element. The light receiving element detects the brightness generated by these patterns superposed one upon another by relative movement of the main scale with respect to the index scale. The linear encoder further comprises pattern end detecting means for detecting the end portion of the measuring pattern provided on the main scale so that the position of the end portion is used as an origin of the encoder.

摘要： Upper and lower thrust bearing faces and a peripheral radial bearing face are formed to surround peripheral and end portions of a disk provided to a rotating shaft supported by a fluid bearing. Pressurized fluid is supplied to the respective bearing faces from first to third fluid passages to thereby form fluid bearing faces. In order to rotate the rotating shaft, the pressurized fluid is supplied to all the passages to keep the rotating shaft and the disk from contact with a bearing member. In order to brake the rotating shaft, fluid supply to the second passage is interrupted. Thus, the rotating shaft is moved down by pressure on the bearing face on the first passage side and, as a result, the brake member comes in contact with the static portion to apply the brakes.
