Title: Method for treating contaminated soil
Inventor: TAKEYAMA MASAHIRO
IPC: E02D3/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent heavy metal and oil from being eluted in underground water by adding to and mixing with the site produced soil a prescribed wt.% of quick lime to soil and a prescribed wt.% of sodium silicate to the quick lime and injecting a prescribed wt.% of water to the soil to the mixed system, causing hydration reaction to make silicate from heavy metal contained in the site produced soil. SOLUTION: 50-100wt.% of quick lime to soil and 5-10wt.% of sodium silicate to quick lime are added and fully mixed to site produced soil while being agitated. Thereafter, 40wt.% of water to soil is injected in the mixed system. Hydration reaction of quick lime is caused, temperature of the whole mixed system is increased, its viscosity is lowered to increase fluidity, mixing of the soil and the treating agent proceeds to produce calcium hydroxide. The calcium hydroxide reacts with sodium silicate to produce calcium silicate, which is water-insoluble white deposition. Heavy metal in the site produced soil becomes heavy metal ions, and reacts with sodium silicate to produce silicate to produce deposition.

IPC: G11B5/09
Filed: 1992-09-02
Abstract: PURPOSE:To prevent a read head from being magnetized by supplying a demagnetizing current to a write head after data is written. CONSTITUTION:An MR head 11 has a bias element constituted of a soft magnetic film which generates a bias magnetic field by a sense current flowing thereinside.

Since a circuit for supplying a demagnetizing current to the write head after the write operation is provided as above, a read head is protected from magnetization. Particularly when the read head is the MR head 11, it becomes possible to prevent the bias shift resulting from the magnetization of the bias element, and eventually prevent a read error.

Abstract: PURPOSE:To make valve timing selectable without fail at all times by forming a recess in a base cycle just before a higher part of a high speed cam, and regulating any movement of a piston at a position where a timing lever, pivotally supported by one side rocker arm free of rocking motion, comes into contact with this recess. CONSTITUTION:When an engine shifts from low speed driving to high speed one, working oil pressure is conducted to an oil chamber 28 via an oil gallery 21 and an oil passages 33, and each of pistons 25-27 tries to shift against a spring 29. Since one end 40a is situated in a recess 34 and the other end 40b is engaged in an engaging groove 26a, however, each movement of these pistons 25-27 is surely regulated. Afterwards, both rocker arms 1, 2 come to a stationary state on base circles of respective cam 12, 14 and center axes of respective guide holes 22-24 coincide, and since a timing lever 40 also continues such a state that its other end 40b separates from a first engaging groove 26a, at this point of time, the pistons 25, 26 are fitted in the guide holes 22-24 and thereby both theses rocker arms 1, 2 are solidly connected together, and an intake valve 3 is opened or closed by the high speed cam 14.
