摘要： A linear motor has a primary to generate the magnetic field and a toothed secondary lying above the primary which has several projecting sections that are regularly spaced. The recesses defined by the bounding projecting sections have filler pieces of lower permeability than the rest and the resultant surface is completely flat. These filler pieces are made from artificial resin, cast in the recesses. The primary has a cleaning wiper blade made of an elastic material which is in contact with the secondary surface. The design is suitable for a machine tool, using a cylindrical or bar-shaped secondary supported at each end by an immovable part in order to extend the linear movement of the movable part.

摘要： There are disclosed a method of and an apparatus for controlling a track position error of a load such as the workpiece table of a multi-axis machine tool. A feed pulse signal for driving the load is added to a deviation of a present position signal detected of the load from a commanded position signal dependent on the polarity of the deviation. The deviation of the added feed pulse signal from the present position signal of the load is determined, and a drive signal for driving the load is derived from a deviation signal indicative of the last-mentioned deviation. A drive source for driving the load is controlled with the deviation signal.

摘要： PROBLEM TO BE SOLVED: To maintain an air static pressure bearing to a predetermined temperature by a more simple constitution. SOLUTION: A temperature of the air static pressure bearing formed by radial and thrust bearing rings 14, 15, 16, 17 having a porous body 18 is detected by a temperature sensor 23. A difference of this detection temperature and a set temperature previously set in a setter 26 is determined by a comparator 25. Based on the difference signal from the comparator 25, the temperature of the air static pressure bearing is maintained to the set temperature by controlling a temperature of an air for the air static pressure bearing fed from an air feed source 21 for air static pressure bearing to the porous body 18 by a compensation circuit 28 so as to approach this difference signal to zero.

摘要： PROBLEM TO BE SOLVED: To provide a hydrostatic bearing of high strength and a few expensive porous material. SOLUTION: A thrust bearing member 58 opposing to a thrust face of a flange of a revolving shaft has a non-porous ring member 59 fitted in a housing 50. On the face opposing to the above thrust face of the non-porous ring member 59 there area laid concentric circularly at least two porous ring members 60. A radial bearing member 55 rotatably retaining an outer surface of a revolving shaft 52 is integrally formed by laying and unifying plurality of porous ring members 53 and non-porous ring members 54 of the same inner and outer diameter by turns to axis direction. Compressed gas is supplied to the above porous ring members 53 and 60 from an air supply opening 62 provided in the housing 50.

摘要： PROBLEM TO BE SOLVED: To provide a spindle unit capable of attaining ultra precision processing or very high speed processing. SOLUTION: The rotating shaft part 1 of a spindle is supported by a radial bearing 2 of pneumatic static pressure bearing type. The rotating shaft part 1 is constituted of glass ceramics. This spindle unit can minimize the expansion amount of the diameter of the rotating shaft caused by high-speed rotation, therefore it is possible to set a clearance between the radial bearing 2 and the rotating shaft part 1 at a very small value. By using the spindle unit in a machine tool, it is also possible to attain ultra precision processing or very high speed processing.

摘要： PROBLEM TO BE SOLVED: To form a rib, excellent in dimensional accuracy and cross section shape accuracy, by relatively less processes and a short time, in forming many fine ribs arranged in parallel on a platelike base plate, such as the manufacture of the back surface panel base plate of a plasma display panel. SOLUTION: The grooves 16 having width W and a pitch P are formed on concave types 11, and grid-like members 21 are formed by arraying platelike members 23, engagged into the grooves 16, in parallel with each other. Concave parts; demarcated by the grooves of the concave types 11 and the grid-like members 21, and having given depth; are formed by inserting the grid-like members 21 into the grooves 16 formed on the concave types 11, and adjusting the inserted depth. Glass paste 51 is packed into the concave parts to abut on a base plate 41 in this condition, and then only the concave parts 11 are parted from the base plate 41, after that, the grid-like members 21 are parted from the glass paste 51, and finally the glass paste 51 is hardened to form ribs.

摘要： PROBLEM TO BE SOLVED: To lubricate those parts to be lubricated by a low cost and low space device by applying a high frequency voltage to a ultrasonic transducer element immersed in lubricating oil and exciting it at a transmitting frequency near resonance point so as to atomize oil from an oil surface and filling the atomized oil into a case in which those parts be lubricated are stored. SOLUTION: A ultrasonic type fog lubricator 30 assembled into the inside of a gear box 10 is provided in a space under the gear box 10, and provided with a ultrasonic transducer 34 which is immersed in the oil contained in an oil reservoir 31 to feed oil properly from a lubricating oil feed means 32. Also the ultrasonic transducer 34 of, for example, 20mm in diameter and 1.2mm in thickness is excited at a transmitting frequency of 2.4MHz, and a distance H between the oil level and the transducer 34 is held at 30 to 70mm. Then a float switch 38 is set according to the upper and lower limits of the oil level, and atomization is performed within this range. When atomized oil is released in this condition, the gear box 10 is filled with atomized oil, effectively lubricating gears and bearings.
