Abstract: PURPOSE:To maintain signal-to-noise ratio stably at all times and to measure a current with high accuracy by controlling the light output of a light source based on a DC component signal extracted from an electric signal obtained by a light receiving circuit. CONSTITUTION:Standard light emitted by a light emitting diode 3a of a light source circuit 3 is propagated in an optical fiber 2a, passed through a probe part 2 equipped with a magnetooptic element, and then propagated again in an optical fiber 2b to impinge on the photodiode 4a of the light receiving circuit 4, so that the light is converted into an electric signal. Then, the signal is passed through an amplifier circuit 5 to extract its AC component signal by a high-pass filter circuit 56 and its DC component signal by a low-pass filter 7; and a divider 8 calculates the ratio of the AC component signal to the DC component signal and outputs the ratio as current setting information. The extracted DC component signal, on the other hand, is inputted to a light output control circuit 9 and returned to and maintained at a proper value when the light output of the light emitting diode 3a varies.

Title: Optical isolator
Inventor: NODA JIYUICHI
IPC: G02F1/09
Filed: 1981-08-14
Abstract: PURPOSE:To constitute an optical isolator even with a double refractive crystal, by arranging two sheets of double refractive crystal so as to eliminate the effect of the double refraction. CONSTITUTION:Linear polarized wave light is made incident to the axis (a) which is vertical to the axis (c) of a magnetooptic crystal having large thickness. Thus the output light is turned into an oval polarized wave due to the double refraction. In this case, a Faraday rotational angle theta equals to (180Ft/piB)sin(piB/ 180), where B=360(no-ne)t/lambda, F: Faraday rotational coefficient, lambda: wavelength of light, no: refractive index of normal light, ne: refractive index of abnormal light and B: phase delay angle due to the double refraction. Then the two crystals having the same thickness along the direction 6 of easy magnetization of the crystal are provided as shown in the figure so that the axes (c) of the crystals are orthogonal to each other. Thus the delay angle B equals to 360/lambda{(no- ne)t+(ne-no)t}=0, and theta=2Ft is obtained. This is identical with an equation of an isotropic magnetooptical material showing no double refraction.

Title: Membrane separation activated sludge process
Inventor: IWASAKI KATSUMI
IPC: B01D65/06
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To ensure a high permeation flow rate by introducing a ferrite powder added water to be treated into a bioreaction tank having a filter module having a metal made separation membrane and evacuating an interior of the filter module to obtain treated water and cleaning a surface of the metal made separation membrane with the ferrite powder. SOLUTION: In polluted water containing organic substances, the organic substances are decomposed by a microorganism actively moved by bubbling air supplied into the polluted water through an aeration pipe 3 in a bioreaction tank 1. Part of fine particles in activated sludge in the polluted water adhere on a surface of a metal made separation membrane of a filter module 2 arranged in the bioreaction tank 1. In this case, because ferrite powder 6 dispersed in the polluted water in the bioreaction tank 1 is made to always flow by the air supplied through the aeration pipe 3, the surface of the separation membrane is cleaned by the ferrite powder 6 so that adhesion and sedimentation of the organic substances on the surface of the membrane is suppressed. By this, a compact-designed treatment apparatus becomes possible and decrease in permeation flow rate is effectively prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head designed in such a manner that a magnetic head chip is parallel moved without inclining this chip and that the grounding of the magnetic head chip is completely executed without the influence of the coating weight and shrinkage rate of an adhesive. SOLUTION: At the time of installing the magnetic head chip 1 onto a base 3 for fixing, the magnetic head chip is adhered thereto via hollow particulates 2 of a synthetic resin and the regulated head height is adjusted by applying pressing force thereon to deform the hollow particulates 2 and, therefore, the height adjustment of the magnetic head chip 1 in a parallel state is made possible and the contact state of a magnetic tape sliding surface is good as well. Since the volume of the adhesive resin is small, the occurrence of the azimuth change and the fluctuation in the head height by the variation of the shrinkage rate of the resin is averted and the grounding of the magnetic head chip 1 by the hollow particulates 2 consisting of the conductive resin is made possible.
