    Abstract: An electro-coagulation printer uses an electrode control unit to drive electrodes (22) which are aligned in proximity to a rotation drum (24) 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 (3) from a hos t device (2) by way of an interface (4). Gradation data representing gradation values for one line of the electrodes are created based on the pri nt 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. That is, output timings of the gradation values are independently controlled based on correction information such that print positions of the ink dots are corrected in at least one of a paper-feed direction and an alignment direction of the electrodes. Based on the gradation values, pulse signals are generated to drive the electrodes respectively. Herein, each of the pulse signals consists of a number of pulses designated by the gradation value, or each of them consists of a single pulse whose pulse width depends on the gradation value. It is possible to differ the pulse signals from each other in phases. Thus, it is possible to print desired images on papers with a high quality and at a high speed.

    Abstract: A double line electrode unit for use in an electro-coagulation printer contains a pair of electrode plates, negative electrodes and a prepreg (or an insulatin g layer). The negative electrodes are linearly arranged with prescribed intervals of distance therebetween on surfaces of the electrode plates respectively and are enclos ed insulating resin materials being solidified. The insulating resin materials contain fillers that are selected from among prescribed materials of boron nitride, aluminum nitride, alumina and silica. In addition, connectors are arranged on other surfaces of the electrode plates in connection with the negative electrodes respectively . The electrode plates are consolidated under heating and pressurized conditions b y way of the prepreg such that the negative electrodes respectively arranged on the surfaces of the electrode plates face with each other by intervention of the prepreg, which has a prescribed thickness and is made by fabric material such as glass fibers impregnated with unhardened resin. After filling and solidifying the insulating resin materials on the negative electrodes of the electrode plates, inspection is performed suc h that electrification is made with respect to each of basic units of negative electrodes to locate an electrification failure area. Then, the complete electrode plate i s made by joining together a prescribed number of the basic units of negative electrod es excluding a basic unit of negative electrodes corresponding to the electrification failure area, which is cut and removed.

    Abstract: A waste liquid processing method comprising a solvent separation process for separating a chlorine-based organic solvent contained in a waste liquid; a first vaporization process that includes vaporization of the chlorine-based organic solvent remaining in the waste liquid after the solvent separation process; a collection process for collecting substances other than the chlorine-based organic solvent contained in the waste liquid after being vaporized in the first vaporization process; a second vaporization process for vaporizing the chlorine-based organic solvent remaining in the waste liquid after the first vaporization process and the collection process; a photo-oxidative decomposition process where photo-oxidation is used to decompose a chlorine-based organic gas generated in the first vaporization process and in the second vaporization process, and a post-treatment process for carrying out adsorption, absorption, and neutralization of a decomposition product gas generated in the photo-oxidative decomposition process.
