Abstract: PURPOSE:To increase polishing speed in the polishing device of a sapphire needle, etc. by supporting a rotary cylindrical body, on which an abrasive in applied or embedded, with a fluid-bearing spindle, bringing a workpiece in contact with it by pressure, and moving it with a fluid-bearing slider. CONSTITUTION:A rotary cylindrical body 18 on which an abrasive 30 is applied or embedded, rotates at high speed, being supported by a fluid-bearing spindle 14. On the other hand, a workpiece 23 consisting of diamond or sapphire, etc. is mounted on a mounting rod 24, fixed to a rotatable workholder 25, pressed against a rotary cylinder body 18 through a pressing spring 29, and moved in parallel by means of an air-slider moving bed 20, a feed screw 22 and a feed motor 21, and polished.

Filed: 1988-07-18
Abstract: PURPOSE:To miniaturize the device and to reduce maintenance frequency by arranging a plurality of electromagnet on the periphery of a cylinder made of non-magnetic material, with a plunger composed of a magnetic material. CONSTITUTION:When electromagnets 2-1, 2-2 put around the both sides of a cylinder 1 made of non-magnetic material are excited alternately in a predetermined period of time, a plunger 4 composed of a magnetic material in the cylinder 1 is moved alternately according to the excitation of electromagnets 2-1, 2-2.

IPC: B23H1/02
Filed: 1982-10-08
Abstract: PURPOSE:To enable a short-circuit between an electrode and a work due to the cutting of electric discharge machining to be prevented by allowing the electrode to jump. CONSTITUTION:When a work is moved by a motor 105 in accordance with NC data of a tape 101 and machined by an electrified electrode EP, if a short-circuit between the electrode and the work is caused by the cutting of a machine, a short-circuit signal SS is input to an input/output board 102f, and a processor 102a interrupts execution of a machining control program but executes the program of a program memory 102b through a bus 102i. In this way, a backward pulse BS in the reverse direction is generated from a pulse distributor 103, and the content of an error register 107b becomes zero after a prescribed time, causing the electrode EP to move backward and jump by the backward pulse. If the short-circuit is released, the signal SS disappears while the processor 102a detects disappearance of this signal, causing the electrode EP to advance and restart its machining feed.

CONSTITUTION:While clamping a movable mold 5 to a stationary mold 4, the nozzle 2 on a cylinder 1-tip is caused to be in contact with the injection port of the mold 4. Molten resin kept in the cylinder 1 is poured into the mold cavity and a product 6 (numeral 7 is its sprue) is molded. Next, immediately after the cylinder 1 has been retracted, air is supplied from an air pipe 9 to the final end 8 of the sprue by which the mold 4 is connected with the tip of the nozzle 2 in filamentous state thereby causing it to be hard by cooling and to be brittle. Next, when the movable mold 5 has been retracted, the sprue and its final end 8 are cut off under their own weight and drop outside of the stationary mold 4. Then the molded product to which the sprue 7 is stuck, drops inbetween the mold 4 and 5 and is recovered.

Abstract: PURPOSE:To eliminate excess and deficiency of spectral informations and thereby to improve precision in measurement by moving a light-sensing element array in the direction of dispersion so that degrees of spectral response be on a continuous smooth curve connecting the barycentric wavelengths of spectral response characteristics being adjacent to each other. CONSTITUTION:A light-sensing element (photodiode array) 3 is moved in the direction of dispersion so that spectral response characteristics obtained by a combination of a dispersion element (continuous interference filter) 2 and degrees of spectral response of compounded spectral response characteristics of adjacent combinations of the elements 2 and 3 be at positions whereat they are not discontinuous, but are on a continuous smooth curve connecting the barycentric wavelengths of the spectral response characteristics being adjacent to each other. Outputs of the element 3 are detected on the occasion. With the element 3 moved, the outputs of the element 3 at positions whereat these conditions are satisfied are detected. When measurement is executed over the whole range of wavelengths to be subjected to spectrometry, then, a spectrum band half-width and a measured wavelength centering interval can be made to accord with each other in any part of the range of wavelengths, and thereby the spectrometry being precise in measurement and free from excess and deficiency of spectral informations (data) is realized.
