Title: Magneto-optical recording medium
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/10
Filed: 1990-05-18
Abstract: PURPOSE:To improve recording density compensating each others drawbacks by magnetically coupling two layers of magneto-optical recording films having the magneto-optical effect to short wavelength light and the performances with perpendicular magnetically anisotropic energy opposite from each other. CONSTITUTION:The 1st, 2nd magneto-optical recording films 3-1, 3-2 are formed via a dielectric film 2 on a substrate 1. The films 3-1, 3-2 are magnetically coupled and the film 3-1 is formed on the incident side of a laser beam. The film 3-1 has the small perpendicular magnetically anisotropic energy but has the high magneto-optical effect to the light of short wavelengths. On the other hand, the film 3-2 has the small anisotropic energy but has the poor wavelength characteristics of the magneto-optical effect. The two films 3-1, 3-2 which have such opposite performances are magnetically coupled, by which the each other's drawbacks are compensated and the recording films having the large anisotropic energy and having the high magneto-optical effect even to the short wavelength light are obtd. High-density recording is thus possible.

Title: Apparatus for cleaning turbid water in dam
Inventor: OI YUKIO
IPC: E02B15/00
Filed: 1985-06-11
Abstract: PURPOSE:To make it possible to cope with any pollutant with suitable selection of precipitation, floatation, and attachment for removal of turbid substances, by restricting the flow of a lake to form a rapid stream by a fence and supplying and mixing flocculants and surfactants in the rapid stream. CONSTITUTION:A fence 18 is suspended down around an intake 14 from the surface of water below a tamp. -jumping layer T. The flow passes through a channel 30 and an opening 24, and its velocity increases locally. The channel 30 promotes mixing of entering lake water with agents supplied. When it is desired to precipitate pollutants, a precipitating accelerator is supplied. In this case, the pollutants are flocculated after passing the opening 24 and precipitate with the reduction in flow velocity. At this time, if bubbles are generated from a bubble generator 36, the mixing and stirring can be promoted. In the case of an advancedly lutrophicated lake, a surfactant is supplied, the bubbles from the bubble generator 36 are allowed to attach to the turbid substances to float and separate the pollutants 42.
