Patent application number	Description	Published
20090081928	BLASTING TREATING METHOD - A method of blasting hazardous substance or explosive in a pressure vessel is provided to improve efficiency while suppressing enlargement of the pressure vessel. To achieve it, the method includes an installing step of installing two or more articles to be treated at a certain spacing in the pressure vessel, an initial blasting step of blasting one of the articles to be treated, and a following blasting step of blasting the article to be treated next to the previously blasted article to be treated after a particular time from the instant of the previous blast. Each of the articles is blasted sequentially through the initial and following blasting steps.	03-26-2009
20090095146	PRESSURE-RESISTANT VESSEL AND BLASTING FACILITY HAVING THE SAME - An object of the present invention is to improve durability of a pressure vessel for blasting an article to be treated such as hazardous substance or explosive therein. The pressure vessel	04-16-2009
20100292525	Method of processing waste material - An aspect of the present invention is a method of processing a waste material that contains mercury or a mercury compound, and chlorine or a mercury chloride, the method including a step of adding a chlorine scavenger to the waste material, and stowing the waste material in a treatment vessel; and a step of subjecting the waste material to a blasting treatment by fitting an explosive to the treatment vessel and detonating the explosive inside a pressure-proof container.	11-18-2010

20090013762	Apparatus for estimating residual life of blasting vessel, method of estimating residual life, and blasting facility - The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge	01-15-2009
20090131733	Blasting system and blasting method - The object is to rapidly clean-up an off-gas generated by blasting in a pressure vessel to such a level as to permit the exhaust of the off-gas. An object to be blasted is blasted in a pressure vessel to generate an off-gas, which is introduced into a combustion furnace to burning a combustible component contained in the off-gas. The off-gas after the burning in a reservoir section is stored in the reservoir section, and exhausted out of the reservoir section if a component contained in the off-gas complies a predetermined emission requirement, otherwise returned to at least one of the pressure vessel and the combustion furnace to be re-treated if the component does not comply the emission requirement.	05-21-2009
20090165636	Method of Cleaning Inside of Pressure Vessel for Blasting - Provided is a method of cleaning the inside of a pressure vessel for blasting to enable a short-time treatment regardless of the state of residual substances. This method includes: a step of setting an explosive for cleaning, different from an explosive for blasting, in an amount necessary for decomposing a residue of the object inside of a pressure vessel after a blasting step of setting and blasting the object and the explosive for blasting in the pressure vessel; and a step of decomposing the residue by exploding the explosive for cleaning in the pressure vessel.	07-02-2009
20090260509	Pressure Container - It is intended to provide a pressure container which can prevent dispersion of a hazardous substance or the like to the exterior and ensure a high level of safety with a simple structure. To achieve this object, a pressure container (	10-22-2009
