Title: Length measuring system
Inventor: HACHISUGA MASARU
IPC: G01B11/02
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a length measuring system in which measuring precision is not influenced by air fluctuation. SOLUTION: An interferometer 4 is put as the position relation of a mirror 2 fixed on a moving object A is in accordance with Abbe's principle. An ultrasonic (b) transmitting and receiving device 5 is put adjacent to the interferometer 4. A wave processor 6 detects a time (t) when an ultrasonic wave (b) goes and comes back between the device 5 and the mirror 2, and a correction device 11 environmentally corrects wavelength of a laser beam a1 by output of sensors 8, 9, 10. After a processor 12 calculates the approximate value L' of the displacement amount of the moving object A by making the half value of the wavelength which the correction device 11 corrects one scale, the average absolute temperature TAVE of the atmosphere is calculated by the approximate value L' and the time (t) when a waveform processor 6 detects.  The wavelength of the laser beam a1 is environmentally corrected again by means of the average absolute temperature TAVE of the atmosphere as Edlen type temperature parameter. Finally, the processor 12 calculates the normal displacement amount of the moving object A by making the half value of the wavelength in which it environmentally corrects a scale.

Abstract: PURPOSE:To obtain high-wave length resolution and high diffraction efficiency in an X-ray and a soft X-ray wave length areas by composing a spectral element by means of a metal intensive fluorine crystal. CONSTITUTION:A metal-enclosing fullerene crystal includes metal such as La, Y and Sc in a spherical net and a cylindrical net composed of combination of more than tens of carbon atoms and are regularly three-dimensionally arranged in a molecular unit.

Inventor: TSUKADA KENICHI
IPC: B65D85/671
Filed: 1991-01-25
Abstract: PURPOSE:To provide a method of fixing the winding termination of a sheet shaped wound body in which a plastic sheet is wound in roll-superimposed relation wherein the termination can be fixed not destroying the wind, moreover, the superficial property of the sheet shaped wound body is not damaged at the time of starting the use of the sheet shaped wound body. CONSTITUTION:The initiation end 5 of a stretch film 4 having a self- adhesiveness is adhered to the outer peripheral surface of a sheet shaped wound body 2, and thereafter the stretch film 4 is wound round the outer periphery of the sheet shaped wound body 2 so that respective stretch films 4 are adhered to each other through their self-adhesiveness. In the stretch films 4, although respective stretch films can be adhered together, however, since they are hard to be adhered to other substances, the sheet shaped body 1 is not damaged in its superficial property when the stretch film 4 is removed therefrom. In addition, the adhesive strength of a label 6 can be weakened to the degree of not separating until the stretch film 4 is completed in winding, whereby the superficial property of the sheet shaped body 1 is not damaged even when the label 6 is removed.

Filed: 1988-02-08
Abstract: PURPOSE:To surely detect the breakage of a wire by installing a wire feeding roller for continuously applying feed onto the wire at a speed lower than the ordinary wire feeding speed during the electric discharge machining in a wire passage between a wire breakage detecting device and a wire reel. CONSTITUTION:A wire feeding roller 5 is driven by a motor M, and the wire on an upper guide 2 side is continuously applied with the feed at the speed lower than the ordinary wire speed during the electric discharge machining. Therefore, the tension of a wire 3 between the wire feeding roller 5 and a wire return preventing mechanism 19 (consisting of roller 8 and a pinch roller 9) reduces when the wire is broken in the vicinity of a work 17, and the wire 3 which looses the tension due to a feed roller 14 is loosened as shown by the broken line. The pick-up 4' of a detecting device 4 detects the loosening of the wire 3 as breakage of wire.

Filed: 1982-02-23
Abstract: PURPOSE:To simplify the operating mechanism of a Josephson NDRO storage circuit whose 2nd switching element is installed in the control line of the 1st switching element, by changing the direction of the electric current flowing to the control line at the time of writing and reading out, respectively. CONSTITUTION:To make to flow a circulating electric current Iciuc to a superconductive closed loop of A, a bias electric current IY and control electric currents IX0 and IY' are simultaneously made to flow to a row line 5 and control lines 7 and 6 and, after a switching element 8 is set to a voltage condition, all the electric currents are set to ''0''. The IX0 is the electric current which flows through the line 7 at the time of writing and the -IX0 is the electric current which flows through the line 7 at the time of reading out. To read out whether the circulating electric current flows through the loop 2, the bias electric current IY and control electric current -IX0 are simultaneously made to flow. When the circulating electric current is held, a switch 9 is set to a voltage condition and it is discriminated by a detector 13. In this way, the number of wirings and power sources are reduced and the operating mechanism of this circuit is simplified.
