Title: Method for regenerating catalyst for wet oxidation treatment
Inventor: MAEDA SHINJI
IPC: B01J23/70
Filed: 1995-06-28
Abstract: PURPOSE: To efficiently regenerate a solid catalyst contg. a metal such as Ti deteriorated by use in wet oxidation treatment of waste water by bringing the catalyst having reduced activity into contact with a regenerating soln. contg. an ammonium salt and ammonia under specified reaction conditions. CONSTITUTION: When a solid catalyst contg. at least one kind of element selected from among Ti, Si, Al, etc., is used in wet oxidation treatment of waste water in a wet oxidizing apparatus, the activity of the catalyst is reduced by poisoning by alkaline earth metals or oxidation with excess oxygen. This deteriorated catalyst is brought into contact with a regenerating soln. of pH 3-10 contg. at least one kind of ammonium salt selected from among ammonium sulfate, ammonium chloride and ammonium carbonate or the ammonium salt and ammonia at 50-370 deg.C under such a pressure as to keep the liq. phase of the regenerating soln. without feeding oxygen. This regeneration treatment is carried out in the wet oxidizing apparatus by suspending the feed of air and sodium carbonate and feeding the regenerating soln.

Abstract: PURPOSE:To prevent generation of a pattern specific to binarization and to avoid deterioration in the resolution for a line drawing and a character by adaptively changing a comparator threshold level in the case of quantizing an output picture data in which a quantized error around an area of a noted picture data is fed back to a multi-gradation digital picture data noted. CONSTITUTION:An intermediate tone original of multigradation is read by a read section 1, an analog picture data outputted from the read section 1 is read and corrected by a picture signal correction section 2 based on a value referenced from a gamma correction table 3 in response to the characteristic of a reader and recorder and converted into a 6-bit multi-gradation digital picture data by an A/D converter section 4. The multi-gradation digital picture is binarized by a pseudo intermediate binarizing section 5 and a binarized data is sent to a coding section 7. Then the threshold level decided adaptively when the signal is binarized by the pseudo intermediate binarizing section 5 is inputted from a threshold level decision section 6 to the pseudo intermediate binarizing section 5. Thus, in the case of binarizing coding, the production of the specific pattern is avoided and sufficient resolution is obtained when a line drawing or a character is binarized.

Abstract: PURPOSE:To obtain a more distinct sound from an audio appliance by shaping a sine wave inputted from an AC power source, to an arbitrary trapezoidal wave by a waveform shaping circuit, and also, correcting a crest value of the trapezoidal wave by a crest value correcting circuit in accordance with its shaping degree, thereafter, inputting it to a load body through an amplifier. CONSTITUTION:A sine wave inputted from an AC power source 4 is shaped to an arbitrary trapezoidal wave by a waveform shaping circuit 1, and also, the crest value of the trapezoidal wave is corrected by a crest value correcting circuit 2 in accordance with its shaping degree, thereafter, it is inputted to a loading body through an amplifier 3. For instance, when its shaping degree is comparatively small, the shaped trapezoidal wave holds a somewhat larger electric energy than the original sine wave compared with an original sine wave, a crest value correcting circuit 3 makes the crest value of the trapezoidal wave a little smaller. Usually, this device displays a function for returning the electric energy held by the trapezoidal wave whose crest value has been corrected, to the same level as the electric energy held by the original sine wave. In such a way, a distinct sound is obtained from the audio appliance.
