IPC: B01D53/86
Filed: 1979-01-12
Abstract: PURPOSE: To permit the removal of NO x  by a dry type denitrification method involving a low temperature reaction by the procedure in which NH 3  is added to NO x - containing waste gas and then the waste gas is passed through a catalyst layer in  order to decompose part of NO x  and also to collect the other part in the form of  salts on the catalyst layer which is, in turn, regenerated by reductive gas.  
     CONSTITUTION: A NO x -containing waste gas 1 is adjusted its temperature to room temperature to 150°C, then mixed with NH 3  gas, and then passed through the catalyst layers 7 and 8 where part of NO x  are decomposed into N 2  and the other part is collected on the catalyst in the form of NH 4 NO 3  and NH 4 NO 2 . The deactivated catalyst due to the adhesion of the NH 4  salts in increasing amounts is then regenerated by passing a 250 to 450°C N 2  gas containing a reducing agent, e.g., methanol, NH 3 , etc., through the catalyst and at the same time the nitrogenous compounds are decomposed into N 2 . As catalyst, activated carbon or alumina on which the oxides of Fe, V, Mn, Cu, Ni, etc., are supported is used. In the case of fixed bed method, using a plural number of the reactors 5 and 6, an alternate operation of the NO x  removal process and the catalyst regeneration process is advisable.

Title: Electrophotographic photoreceptor
Inventor: SHIRAI SHINJI
IPC: G03G5/04
Filed: 1995-01-10
Abstract: PURPOSE: To attain stabilization against ozone and UV and to stabilize characteristics over a long period of time by incorporating a specified quinalkaloid as an additive into a photosensitive layer. CONSTITUTION: In this electrophotographic photoreceptor with a photo-sensitive layer on the electrically conductive substrate, a quinalkaloid represented by formula I, II, III or IV is contained as an additive in the photosensitive layer. The quinalkaloids represented by the formulae I-IV are cinchonine, cinchonidine, quinine and quinidine, respectively. Even when this photoreceptor is allowed to stand in an ozone atmosphere or stress is applied by irradiation with intense light or other method, this photoreceptor undergoes no change in the potential characteristics and sensitivity characteristics with the lapse of time.  The reason for no change is that an org. substance forming the photosensitive layer is not deteriorated by oxidation with ozone generated in an electrifying process and it is not deteriorated by a photoreaction even in the case of exposure to intense external light at the time of maintenance.

Title: Method and apparatus for forming thin film by cvd
Inventor: KATSURAI KUMIKO
IPC: H01L21/205
Filed: 1988-01-07
Abstract: PURPOSE:To prevent the mixing of impurities into a grown thin film by a method wherein reaction gas in a solid phase or a liquid phase is absorbed into a substrate in the first vacuum chamber, and energy rays are made to irradiate on the gas absorbed into the substrate. CONSTITUTION:The substrate holder 4, on which a substrate S is installed, is placed on the supporting stand 3 located in the first vacuum chamber 1A. The temperature of the substrate S is brought to the liquefying temperature or the solidifying temperature or below of reaction gas by the temperature adjusting means 10 located in the supporting stand 3. As a result, the reaction gas introduced into the vacuum chamber 1A is absorbed to the substrate S in a liquid phase or in a solid phase. Then, the substrate S passes through an aperture part 12 together with the holder 4, it is shifted to the second vacuum chamber 1B and placed on the supporting stand 3. The energy rays such as the ultraviolet rays and the like sent from a light source 5 are projected on the reaction gas absorbed to the substrate S through an optical system 6 and a window 7. A photochemical reaction is generated and a thin film is formed on the substrate S. As reactive gas is not diffused in the vacuum chamber 1B, no reaction product is adhered to the inner wall of the vacuum chamber 1B, and the cause of mixing impurities into a film can be removed.

Abstract: PROBLEM TO BE SOLVED: To simultaneously finish up both the outer surface and the inside of frozen food by equipping a temperature controller and a near/far-infrared heater with a specific wavelength at the upper portion of a toasting net, and energizing the near-infrared heater continuously and the far-infrared heater intermittently in conduction. SOLUTION: When an object 10 to be cooked of frozen food is placed on a toasting net 7 and a switch 13 is switched for energizing a near-infrared upper heater 4, a far-infrared upper heater 5, and a far-infrared lower heater 6, the near-infrared heater 4 with a radiation peak at a band with a wavelength of 1.5 μm or less is continuously energized. Radiation heat to be discharged reaches the inside of the object 10 to be cooked and increases its internal temperature. Radiation heat being discharged from the far-infrared heaters 5 and 6 with a wavelength of 1.5 μm or more reaches the outer surface of the object 10 to be cooked such as bread that is energized and frozen intermittently via a temperature controller 11 and a timer and burns the outer surface.  The best timing for eating can be determined when the outer surface of the object 10 to be cooked is burned appropriately when viewed from an observation window 8 since the inside of the object 10 to be cooked is heated appropriately.
