摘要:
A decomposition processing method for ethylene oxide is provided for when concentration of the ethylene oxide to be decomposed in a gas varies. The method comprises steps of reducing the concentration of ethylene oxide in the gas to a predetermined concentration which is less than the highest concentration of the ethylene oxide in the range of the variation, adsorbing ethylene oxide to a photocatalyst which has ethylene oxide adsorbing ability, and decomposing ethylene oxide by action of one of the photocatalyst and a combination of the photocatalyst and plasma. The adsorbing step and decomposing step are conducted after the reducing step.

An electro-coagulation printer is basically constructed by a rotation drum having a circumferential surface which is electrified in positive potential, a number of electrodes which are selectively electrified in negative potentials, and an ink supply device. The electrodes are aligned to oppositely face with the circumferential surface of the rotation drum with a gap which ranges between thirty and one-hundred microns. The ink supply device is arranged in an incoming side of the rotation drum and supplies liquid ink to be injected onto the circumferential surface of the rotation drum, so that electrification is performed between the electrodes and circumferential surface of the rotation drum with intervention of the liquid ink. Thus, a desired image is formed on the circumferential surface of the rotation drum and is transferred onto a printing material such as a paper. In order to prevent the liquid ink from being stuck to surfaces and peripheral portions of the electrodes, electrolyte containing substantially no coagulating components is supplied to the electrodes. Namely, an ink film thickness regulation roller is provided to regulate the liquid ink to a prescribed thickness (T1) which is smaller than the gap, while a gap of a remaining thickness (T2) is filled with the electrolyte. Thus, electrification is performed in such a manner that the liquid ink having the prescribed thickness is placed on the circumferential surface of the rotation drum, while the electrolyte is placed in contact with the electrodes, wherein the liquid ink and electrolyte are arranged in different phases.

A gas treatment method is actualized by arranging a plurality of photocatalyst members each including photocatalyst, solid substance, and catalyst in a region of non-equilibrium plasma, which is produced using a surface discharge electrode and into which a treated gas such as an exhaust gas and a harmful gas including harmful chemical substances is introduced and is then subjected to decomposition. The surface discharge electrode comprises a ground electrode, an insulator encompassing the ground electrode, and a plurality of surface electrodes that are arranged relative to the ground electrode via the insulator, by which the non-equilibrium plasma is produced upon electrification. A gas treatment apparatus is constituted by arranging a plurality of surface discharge electrodes, each having a plurality of through holes penetrating in a thickness direction, between which a plurality of photocatalyst members are arranged.

An electro-coagulation printer uses an electrode control unit to drive electrodes which are aligned in proximity to a rotation drum having a conductive ink film on its surface. The electrodes are respectively electrified to partially coagulate the conductive ink film to form ink dots on the surface of the rotation drum, so that the ink dots are transferred onto a paper. Herein, the electrode control unit receives print data from a host device by way of an interface. Gradation data representing gradation values for one line of the electrodes are created based on the print data and are output in a serial manner. The serial gradation data are converted to parallel data corresponding to the gradation values, which are held and controlled in output timing. Based on the gradation values, pulse signals are generated to drive the electrodes respectively.
