Title: Magneto-optical film for magnetic field sensor
Inventor: ASAHARA YOSUKE
IPC: G02F1/09
Filed: 1990-02-28
Abstract: PURPOSE:To obtain the magneto-optical film for sensors which can detect a nonuniformity of slight magnetic fields and micromagnetic fields by epitaxially growing a magnetic garnet film of (GdBi)3(FexAly)O12 on a gadolinium gallium garnet single crystal substrate. CONSTITUTION:The satd. magnetization at about room temp. of the magnetic garnet film is due to the Fe<3+> of the d-site and, therefore, if Al<+3> of the radius smaller than the radius of the Fe<3+> is successively added, the Al<3+> substitutes more Al<3+> of the d-site than the Fe<3+> of the a-side and the satd. magnetization decreases. The matching with a lattice constant is taken when the Al<3+> is successively added and, therefore, Bi<3+> of a large radius is taken in a large quantity into the magnetic garnet film and a Faraday rotating constant thetaF increases. The compsn. of (GdBi)3(FexAly)O12 is specified to x+y=5 therein and the adequate amt. of the Al to be added is 0.4<=y<=0.6. The sensitivity coefft. increases when the amt. of the Al to be added is increased. The garnet film 4 and a reflecting film 5 are superposed on the gadolinium gallium garnet single crystal substrate 3 to constitute the sensor element.

Title: Plasma melting method for active metal
Inventor: NISHI SEIJI
IPC: C22B9/20
Filed: 1990-02-26
Abstract: PURPOSE:To inhibit the scattering of a molten metal and to improve melting efficiency without causing reduction in melting yield by using an Ar gas containing He and Ne as a plasma arc producing gas and also forming the atmosphere in a furnace into reduced pressure atmosphere. CONSTITUTION:At the time of subjecting active metals containing sponge material and chip material to plasma melting, a gas prepared by incorporating He gas and Ne gas by >=10% to Ar gas is used as a gas for producing plasma arc. In addition, the inside of a melting furnace is regulated to a reduced pressure atmosphere of <760Torr. By this method, a thermal pinch effect where the cross sectional area of an arc column is reduced can be obtained. Since the plasma arc producing gas is expanded by the quantity equivalent to the increase in width of the arc column and injection power toward the raw material is reduced, the scattering of the molten metal due to the scattering of the chip material and the splashing phenomenon of the sponge material can be inhibited without causing reduction in melting efficiency.

Title: Method and device for preventing image quality deterioration in image area separate processing
Inventor: KITAYAMA HIDEYUKI
IPC: H04N1/40
Filed: 1995-03-07
Abstract: PURPOSE:To prevent the deterioration in image quality when binarization processing is implemented through the use of image area separation processing by discriminating the number of peripheral picture elements resident in an intermediate density area among peripheral picture elements of a noted picture element. CONSTITUTION:A noted picture element density discrimination section 10 discriminates whether or not the density of a noted picture element stays within the range representing an intermediate density area. As a result when the density of the noted picture element is resident in the intermediate density, a density difference discrimination section 12 discriminates a density difference between the noted picture element and its peripheral picture elements. Then a peripheral picture element density discrimination section 14 discriminates the number of the picture elements whose density is the intermediate density among the peripheral picture elements. Then a dither processing circuit 16 applies dither processing to the noted picture element and a simple binarization processing circuit 18 applies simple binarization processing to the noted picture element and a multiplexer 20 provides an output of the signal A after dither processing or a signal B after simple binarization processing depending on a discrimination flag. Thus, black stripes being a cause to image quality deterioration are eliminated to prevent deterioration in the image quality.
