摘要： A linear driving device that reduces a cogging force with a simple structure as opposed to a drive mechanism having an existing structure, deals with a plurality of cogging waveforms having different periods, and suppresses not only the cogging force but also pitching that is vertical oscillation. The device has a structure provided with a plurality of magnet arrays in which permanent magnets having different polarities are alternately and rectilinearly arranged in the same direction, and a plurality of coil modules having a plurality of teeth and slots fitted with armature coils. The arrangement distance between the coil modules disposed along the displacing direction of each of the magnet arrays equals the sum or remainder of the length corresponding to a half of any one of periods possessed by the cogging force generated when the coil modules move by one magnetic pole and an integer multiple of the length of a magnetic pole pair. The coil modules are connected to each other by a connecting member, and the connecting member makes relative motion along the magnet arrays.

摘要： A temperature control system for a machine tool capable of quickly responding to an ambient temperature change. A mechanical section of the machine tool is surrounded by a machine cover. Gas of which temperature is controlled by a temperature controller is discharged from bearing portions of gas bearings in the mechanical section to a region surrounded by the machine cover through a pipe and a gas bearing channel. A branch pipe is provided for directly introducing a part of gas discharged from the temperature controller to a temperature sensor inside the machine cover. The temperature sensor measures the temperature of gas mixture obtained by mixing the gas introduced directly from the pipe with air inside the machine cover in a predetermined ratio. The result of measurement by the temperature sensor is fed back to the temperature controller to control the temperature of the gas supplied to the gas bearings.

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 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 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.
