摘要： A machining apparatus capable of irregularly forming a plurality of dimples on a surface of a workpiece in a short period of time. The machining apparatus includes a tool for machining a plurality of dimples on a surface of a workpiece, each dimple having a depth in a first direction; a drive unit for displacing the tool relative to the workpiece in the first direction and a second direction generally perpendicular to the first direction; a controller for controlling the drive unit so as to displace the tool relative to the workpiece in the first direction such that the tool cuts into or leaves the workpiece, while the tool is being moved relative to the workpiece in the second direction, wherein a trigger of the displacement of the tool in the first direction is timing calculated by using a second waveform, the second waveform being determined by comparing the magnitude of a first waveform with a predetermined threshold, at least one of frequency and amplitude of the first waveform being irregular.

摘要： A sliding member having an attached tool reciprocates along a guide member. Permanent magnets are placed at both ends of the reciprocating motion path of the sliding member and permanent magnets are also placed in positions on the guide member that correspond to stroke ends of the sliding member. At the points at which the motion of the sliding member reverses, the permanent magnets approach one another and generate a repulsive force, thereby accelerating the sliding member.

摘要： A fluid bearing that dampens without requiring a special braking device, and further, without affecting the fluid bearing surfaces. A slide member that is guided by a guide member so as to move linearly is supported by fluid bearing surfaces. The guide member protrudes from the bottom of an opening provided in the bottom of the slide member and its side wall surfaces function as braking surfaces that press against the braking surfaces of the slide member. When fluid of an adequate pressure is supplied to the fluid bearing surfaces, the slide member deforms, a gap appears between the braking surfaces, and further, the slide member, which is supported by the fluid bearing surfaces, enters a state of non-contact with the guide member and the movement of the slide member is damped, thus making it possible to obtain a fluid bearing that can dampen movement without requiring a special braking device, and further, without scratching the bearing surfaces.

摘要： A simple, inexpensive waterproof/dustproof structure for a movable mechanism such as a machine tool apparatus or the like, providing a liquid reservoir formed between the inner wall of a stationary member and the outer wall of a movable member at a portion equivalent to the entrance of a gap between the stationary member and the movable member. The leading edge of the movable member moves through a liquid LQ that fills the liquid reservoir. The liquid LQ seals off the interior of the apparatus from the exterior to prevent the entry of mist, dust and other foreign matter. The gap may be made comparatively broad without affecting the ability to prevent the entry of foreign matter. The direction of movement of the movable member may be longitudinal, lateral, reciprocal, rotary, or a combination thereof, depending on the type of movable mechanism to which the waterproof/dustproof structure is applied. The liquid LQ may be a working fluid used by a hydraulic bearing or a machining fluid used by a machine tool.

摘要： A bolt insertion hole is provided along an edge end portion on a flat surface of a plate-like member, and a tap hole is provided on an end face of the other edge end correspondingly to the bolt insertion hole. A bolt is inserted into the bolt insertion hole and screwed with the tap hole, and a box bearing is formed by means of four plate-like members joined together. The diameter of the bolt insertion hole is made larger than the diameter of the bolt. By changing the insertion position of the bolt with respect to the bolt insertion hole, the distance of a bearing gap inside the bearing, which is formed into the shape of a box, can be adjusted.

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.
