A waste water is supplied by a waste water pump 2 through pipes 1, 3, 5 to a heat exchanger 6 and a heater 8 to be preheated and then supplied through the upper part of the reaction tower 10. Air pressurized by a compressor 4 is introduced to the exit side of the waste water supply pump 2, preheated with the waste water and introduced into the reaction tower 10. The waste water containing org. matters and the air are made to pass as a downward stream in the reaction tower 10 packed with the catalyst under conditions of 100 to 270 deg.C reaction temp. and such pressure to maintain the waste water in a liquid phase.  The treated water and the gas drained from the reaction tower 10 are cooled by a heat exchanger 6 and auxiliary cooling device 13 and introduced to a gas-liquid separator 14 where the mixture is divided into a gas phase and a liquid phase.

IPC: G11B5/133
Filed: 1985-11-25
Abstract: PURPOSE:To form a titled substrate which is thermally stable and has good wear resistance as a nonmagnetic material by using crystallized glass or photosensitive crystallized glass as the nonmagnetic material. CONSTITUTION:MnZn ferrite is used as a soft magnetic ferrite 1 and the photosensitive crystallized glass 2 is used as the nonmagnetic material. NiZn ferrite may be used for the ferrite 1 as well. The MnZn ferrite substrate 1 and the photosensitive crystallized glass base material 2 in an uncrystallized state are subjected to a heat treatment while the pressure 3 shown by an arrow in the figure is kept exerted thereto. This heat treatment softens the photosensitive crystallized glass base material 2 in the uncrystallized state by the heat to weld the material to the MnZn ferrite and crystallizes the base material 2 to provide the thermally and chemically stable state thereto. The wear resistance of the photosensitive crystallized glass is as excellent as the wear resistance of the MnZn ferrite.

Title: Apparatus for processing electrophotographic image and method therefor
Inventor: FUJITA TORU
IPC: B41J2/52
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To reproduce images while restraining generation of feed irregularities and streak irregularities by shifting in a sub scan direction positions of grow cores of halftone dots arranged in a main scan direction and generating image reproduction data when a gradation is expressed by halftone dots formed of a plurality of dots to form images. SOLUTION: When a halftone dot 5 in each cell CELL is large enough to come in touch with a halftone dot in an adjacent cell eventually, in other words, when a density of halftone dots is high, light and shade becomes conspicuous due to generation of feed irregularities and, streaks in a main scan direction become clearly noticeable. As such, grow cores of halftone dots in cells CELL 00-CELL03 arranged in the main scan direction are shifted in position in a sub scan direction when dots are to be formed. For example, the grow core of the halftone dot in the cell CELL01 is positioned at a central upper part of the cell, while the grow core of the halftone dot of the cell CELL03 is positioned at a lower central part of the cell. Feed irregularities in the main scan direction are thus restricted, so that an image quality is improved.

Abstract: PURPOSE:To obtain a preferred capacitor insulating film by adopting a ferroelectric substance having a Curie point of -20 deg.C or lower and using it in a paraelectric phase thereby to prevent polarization and reversal. CONSTITUTION:A thin film of a solid solution (XBaZrO3.cl-X) containing BaZrO3 by 45% or more is adopted as a capacitor insulating film. After a ground electrode 15 of pt is formed, With a photoresist as a mask it is patterned by dry etching. On its surface a solid solution thin film 16 is formed by a high-frequency magnetron sputtering process. The thin film composition is X=0.47. Since it has a Curie point of -20 deg.C or lower it is paraelectric in the guaranteed working temperature range (-20 deg.C-150 deg.C) of DRAMs, no polarization and reversal occurs. With this, a sufficient amount of accumulated charge can be acquired by a capacitor with a simple structure and a small area.

Title: Exhaust emission control device for in-cylinder injection internal combustion engine
Inventor: IWACHIDO KINICHI
IPC: F01N3/28
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent poor fuel consumption and torque variation when recovering the cleaning performance of a NOx catalyst constituting a exhaust cleaning device for an in-cylinder injection internal combustion engine. SOLUTION: If NOx purging conditions are established (S1) when the cleaning efficiency of a NOx catalyst may be lowered, a fuel injection valve is opened/ closed under the control of an electronic control unit to cause sub-injection in expansion strokes after main injection (S2). The main injection and the sub- injection are performed under the restriction of the concentration of oxygen in exhaust gas flowing into the NOx catalyst not to be almost lowered, and so the enrichment of an air/fuel ratio in the main injection and the subsequent change of a fuel injection mode and a great amount of fuel in the sub-injection are avoided.

Abstract: PURPOSE:To evade the excess of a space around a right margin at the time of automatic beginning of new line by detecting a syllable punctuation position below a specific character position in inputted word information if the inputted word information exceeds the specific character position. CONSTITUTION:If the inputted word information exceeds the specific character position, the syllable punctuation position below the specific character position in the inputted word information is detected. It is assumed that 'automatically (space)' is inputted to overflow the printing line width. Then the space width that a cursor indicates is subtracted from the line length, and such decision is made whether 'automatically' can be printed on the same line or not. If so, a printing device 4 prints a text up to the punctuation stored in a line buffer 2. If not, a word dictionary 6 is retrieved by 'automatically'. If it can be found in the dictionary, information about prescribed syllable punctuations is available.

Title: Method for offset printing and image display device using it
Inventor: YONEMOTO KAZUNARI
IPC: B41F3/38
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To shorten a printing tact and to completely transfer print an ink by providing an ink supply unit before a doctor unit to an intaglio pattern, and simultaneously performing supplying of the ink and doctoring. SOLUTION: A doctor blade 4 is mounted at the same horizontal bar as a dispenser 3, and as the bar is moved in a printing direction, ink discharging and doctoring are simultaneously conducted. At this time the ink supply dispenser 3 discharges the ink while moving to reciprocate in a direction perpendicular to the printing direction, and hence the ink is supplied in saw blade shape 6 over the entire surface of the intaglio pattern. Immediately thereafter, since the ink is doctored by the blade 4 mounted at the same bar, printing can be executed without stopping time of the printer. At this time, since the doctoring is conducted immediately after the ink is supplied, no ink is dried, and the ink is charged in a homogeneous state. As a result, printing can be conducted without defect over the whole of pattern.
