IPC: G01J3/26
Filed: 1986-03-04
Abstract: PURPOSE:To enhance wavelength resolving power by widening a spectral diffraction wavelength region, by a method wherein the interval and first and second angles of refraction of interference plates are selected properly and a wavelength intensified by the generation of interference is specified to perform the spectral diffraction only of the specified wavelength. CONSTITUTION:The beam emitted from a beam source 20 is converted to a parallel beam by a collimator lens 21 and incident to Fabry-Perot interference plates 17 so as to set a predetermined angle theta1' of refraction. These interference plates 17 are constituted so that half mirrors having high reflectivity are parallelly held on two planes at a predetermined interval by a piezoelectric element and the interval therebetween is made changeable in a predetermined range. The beam transmitted through said interference plates 17 is reflected by reflecting mirrors 23, 24, 25 to be again incident to the interference plates 17 at a predetermined angle theta2'. Then, by condensing the spectrally diffracted beam by a condensing lens 26, the beam of the beam source 20 can be spectrally diffracted.

Title: Amorphous magnetic material covered with plasma polymerized film
Inventor: FUKAGAWA HIROMASA
IPC: H01F1/153
Filed: 1987-03-02
Abstract: PURPOSE:To enable tight winding and piling of films, reduce core loss and realize a small-sized transformer, etc. CONSTITUTION:After a vacuum container 2 is evacuated and discharging is generated between two electrodes 3 while monomer gas is being supplied through a feed pipe 5, plasma polymerized films are formed on both faces and side faces of an amorphous magnetic body 7 as moving the body 7. Then an amorphous magnetic thin plate having plasma polymerized films is wound on a semi-rectangular frame and formed to manufacture a winding iron core. Further the winding iron core is annealed in nitrogen gas to remove its winding strain. Since the insulation performance is insufficient when the volume resistivity of plasma polymerized film is under 10<7>OMEGA.cm, the eddy current loss increases when the films are used for iron cores. When the transmission of oxigen gas exceeds 10<-12>cc.cm/cm<2>/sec.mmHg, rust-proofness and thermal resistance decrease. When they are used for iron cores at the density of less than 1.3g/cm<3>, the thermal resistance and durability decrease.

Then, for equivalence in converting sport integral numbers into integers, the cases of integer values of respective odd and even numbers indicated with dice in each group are determined, thereby obtaining the standard digital of each random number avaliable therefrom. Groups A to F have independent results and in particular, in the constitution of all integral number surfaces of respective dice except for the groups C, E and F, the dual of normal and reverse symmetric systems is indicated. As a result, each equivalence of integers assignable to dice makes it easy to enlarge, expand and increase viriability in the entropy random number of each system device.

Abstract: PURPOSE:To enable continuous collection of chloride free from an oxide by chlorinating the oxide suspended in a melt salt consisting essentially of chloride in a device divided into a reaction zone and product zone by a filter. CONSTITUTION:The aimed chloride device is divided into a chlorination reaction zone 2 and production zone 3 by a filter 1 through which a melted salt is passed, but oxide (e.g. HgO) grains are not passed. In the above-mentioned device, a mixed bath salt having low chloride concentration and oxide are charged from a raw material charge inlet 4 into the above-mentioned reaction zone 2 and are reacted with chlorine gas from a gas feed inlet 5 to provide chloride (MgCl2).
