Title: Improving method for soft ground
Inventor: HANDA TAKESHI
IPC: E02D3/12
Filed: 1980-07-23
Abstract: PURPOSE: To produce an excessive gap water pressure in the ground and to reinforce the ground through the discharge of drain, by a method wherein a bag substance, whose diameter at its expansion time is larger than that of a bored hole, is placed upright in a hole bored in the ground to be amended, and the bag substnce is expanded by pouring.  
     CONSTITUTION: A pouring inner pipe 9 is inserted into a pouring outer pipe 6, and it is lowered to a lowermost position to pour into a bag substance. The pouring inner pipe 9 provides with a strainer part, and hackers 11 are mounted at the upper and lower parts. The outer pipe 9 can freely move at the inside of the pouring pipe 6, and thereby a pouring material can be poured by press into the desired bag substance. Resulting from the expansion of the bag substance to its original shape through pouring of the pouring material, the expanded bag substance consolidates and reinforces a spherical ground to generate a gap water. So generated gap water penetrates up to the upper part of the bag substance by a capillary phenomenon for the discharge.

Title: Method of coating inner surface of pottery furnace
Inventor: NARITA YUJI
IPC: F27D1/16
Filed: 1991-05-02
Abstract: PURPOSE:To obtain a coating layer, having a high melting point and prominent in fire resistant property, by a method wherein readily oxidizable metallic powder is blended with granular bodies granulated previously by Si powder and light-weight aggregate employing organic binder and is sprayed against the inner surface of a pottery furnace preheated to a temperature higher than 600 deg.C together with oxygen gas. CONSTITUTION:Readily oxidizable metallic powder consisting of combination of the fine powder of Si and rough powder of Mg, for example, is utilized as heat source while aggregate, granulated by basic aggregate previously employing organic resin, for example, is blended as the aggregate for the metallic powder. Said blended substance is sprayed against the inner surface of a pottery furnace, which is preheated to a temperature higher than 600 deg.C, together with oxygen gas whereby a coating layer is formed. Said method utilizes the reaction heat of thermit, which is effected by a metal, and Si powder and Mg powder becomes the liquid drops of SiO2-MgO series after the heat generating reaction and forms the matrix of a metal spray layer. The layer is solidified after forming a configuration.
