Title: Chemical substance decomposition method
Inventor: FUJITA KAZUNORI
IPC: B01J19/10
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To efficiently and quickly decompose toxic chemical substances by utilizing cavitation bubbles generated in a liquid by ultrasonic waves or the like by making catalyst coexist in a solution in a method of generating a high temperature and high pressure by a cavitation bubble generating means and decomposing chemical substances in the solution. SOLUTION: Cavitation bubbles are generated by an ultrasonic oscillation in a solution containing toxic chemical substances to decompose the toxic chemical substances. Namely H and OH radicals are generated following the generation of cavitation bubbles in the vicinity of the cavitation bubbles, and the radicals are reacted with the toxic chemical substances. When the bubbles are formed or collapsed, the temperature and pressure are risen and increased to gasify and pyrolyze or burn volatile compounds (molecular compounds). Namely both of the radical reactions and pyrolysis reaction are actuated. As the mechanism of pyrolysis generated by the cavitation bubbles is the oxidative reaction, it is desirable for the catalyst to be used to adopt an oxidation catalyst for accelerating the oxidation.

Filed: 1986-05-14
Abstract: PURPOSE:To improve the productivity of exposing an electron beam by exposing a second row reversely to a first row in a zigzag when dividing a figure larger than the maximum size allowable for the beam for its exposure, thereby reducing the settling time of deflecting means. CONSTITUTION:When dividing a figure B larger than the maximum size allowable for an electron beam into figure group of the size solely emitting the beam to expose the figure in an electron beam size variable electron beam exposure equipment, the figure B is divided into maximum number to be employed in the maximum sole emitting size in the directions of width Wp and height Hp and two regions of the size larger than the minimum sole emitting size and smaller than the maximum sole emitting size to be exposed, and constructed to be exposed so that the directions of adjacent columns or rows of exposure sequence of the sole emitting region become reverse to one another, i.e., in a zigzag state. Thus, there is no deflecting distance of the beam to be increased when the exposing position is altered to reduce the settling waiting time of the deflecting means, thereby improving the productivity.
