Title: Superconductive current detecting circuit
Inventor: HARADA YUTAKA
IPC: G01R33/035
Filed: 1985-10-30
Abstract: PURPOSE:To detect a superconductive current by using a comparator for amplifying in lock-in mode the output of a DC magnetic flux parametron (DCFP) circuit as an exciting current and a reference input, extracting the exciting current and its frequency component, feeding back and reducing the component to zero. CONSTITUTION:The DCFP circuit is excited by a positive unipolar pulse current of frequency fo. If an input current IS dependent upon the magnetic flux to be detected is larger than a reference current Ir, a positive pulse string synchronized with a current 110 appears as an output current IL, a negative pulse string appears in case of IS<Ir, and when IS=Ir is formed, positive and negative polarity pulse strings appear at the same probability, so that the coincidence between the IS and Ir can be decided. The output IL is lock-in amplified 201 by referring fref(=fo) synchronized with the exciting current 110 and a component fo is extracted. The amplified output 201 is positive in case of Ir<IS, negative in case of Ir>IS and zero in case of IS=Ir. When the output is inverted against the input and used as a reference current for the DCFP circuit, a feedback system converging so as to form IS=Ir is constituted. In said constitution, a current comparator having high performance can be obtained and a superconductive current can be detected hollowing a highly sensitive and rapid signal.

Title: Spectrophotometer
Inventor: IIDA ATSUHIRO
IPC: G01N21/27
Filed: 1989-09-18
Abstract: PURPOSE:To select the best optical path length for samples which vary in transmissivity over a wide range by enabling a sample to rotate on an axis perpendicular to an optical path of measurement and interposing an optical path lateral shift compensating element in the optical path of measurement. CONSTITUTION:Sector mirrors 2 and 2' which rotate synchronously send sample measuring light and reference light through the same optical path to make them incident on a photoelectron amplifying tube 3 of a photodetecting element alternately. A sample cell 4S and a reference cell 4R are supported rotatably on points O respectively and so coupled as to rotate by the same angle in the same direction. Cells 5S and 5R are arranged as lateral shift compensating cells on a sample measuring light optical path S and a reference optical path R and so coupled as to rotate by the same angle in the opposite direction from the cells 4S and 4R. When the cell 4S is rotated by an angle alpha, the sample measuring light optical path shifts laterally by (d). The cell 5S, however, rotates by alpha in the opposite direction and the optical path shifts by (d) in the opposite direction by the cell 5S, so the optical path of light incident on the photodetecting element 3 does not shift laterally.

A circulation pump 7 performs this circulation of water. The magnetizer 6 is an apparatus with which the water flows in magnetic flux between magnetic poles and at least two times of treatment wherein the water in the vessel 1 is passed continuously through the magnetizer 6 and the water is returned to the vessel 1 for circulation are performed. Then upon confirmation of production of the magnet-treated water, kneading is performed by using the magnet-treated water in said vessel as kneading water for cement/mortar or concrete. In order to detect a degree of magnetization of the magnet- treated water, a saturated water of sodium chloride is put a titration instrument 10 and the same is dropped off into a sample water 9 by a predetermined quantity, hence a visible shrinking-neck layer 11 is formed to the upon part of its aqueous phase. Since a state where the layer 11 appears most vividly corresponds to the most magnetized one, the degree of the magnetization is detected through distinction of the states.

Title: Marking method of transparent material
Inventor: HAYASHI KENICHI
IPC: B23K26/00
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To enable the marking to a thin transparent substrate by using a process to prepare a marking object and a process to carry out marking while a laser light in a wavelength area transmitting a material to form the object is condensed inside the object with a fθ lens. SOLUTION: When marking is carried out to, for example, a glass substrate as a thin substrate, it is preferable that the relative position relation between a laser light 3 and a substrate 1 is controlled in a way taking the reflactive index of the substrate into consideration that a focal point is positioned inside the substrate and also at deeper than 1/2 of the thickness of the substrate. A fθ lens 14 keeps the depth of a light condensing point Q approximately constant even if the optical axis is inclined against the substrate face. Cracks 5, 6 due to the optical damage or the optical dielectric breakdown are generated at the point Q of the light 3, to form a mark 7.  The light condensing point is moved per shot by the swing of a galvano mirror or the movement of the substrate 1, so as to form the plural marks 7 dispersed in the face inside direction of the substrate 1, resulting in not damaging the substrate surface.
