Title: Sanitary type degassing apparatus
Inventor: MORI JUNICHIRO
IPC: C02F1/20
Filed: 1986-06-11
Abstract: PURPOSE:To enhance not only deoxidation capacity but also sanitariness, by primarily degassing water to be treated heated to b.p. or less in a vacuum tank and guiding the degassed water to a flash tank while injecting CO2 therein under pressure to rapidly reduce pressure to perform secondary degassing. CONSTITUTION:Water to be treated used in raw water of beer or a soft drink is heated to predetermined temp. equal to or less than b.p. by a heater 2 to be guided to a vacuum tank 4. Primary degassing is performed in the vacuum tank 4 held to a predetermined vacuum degree to remove 90% or more of dissolved oxygen in water to be treated. Next, this water to be treated is pressurized to be guided to a premix tank 9 where CO2 at the time of degassing is blown in said water and, further, CO2 is blown in the water on the outlet side of said tan 9 to be mixed therewith under stirring to guide said water to be treated to a flash tank 18. Since the flash tank is held to almost atmospheric pressure, the pressurized water to be treated is rapidly reduced in pressure and O2 and CO2 not completely dissolved are discharged to perform secondary degassing.

Title: Method of adjusting photosensitivity of photosensor
Inventor: KAJIWARA YUJI
IPC: H01L21/66
Filed: 1988-06-01
Abstract: PURPOSE:To eliminate the unevenness of a sensitivity without providing an external corrective circuit by a method wherein a minute diameter light beam is applied successively to a plurality of sensor devices provided on an insulating substrate and make the light output characteristics of the sensor devices uniform. CONSTITUTION:An amorphous silicon photoconductive film 2 is built up on a transparent glass substrate 1 and a chrome electrode film is formed and patterned into facing electrodes 3 to form the basic structure of a sensor device. Then a laser beam 4 having a laser region 5 is applied to the sensor device through the rear of the glass substrate 1. At that time, the large luminous power is applied to the high sensitivity device and the small luminous power is applied to the low sensitivity device. Therefore, if the intensive light beam is applied to the photoconductive film such as the amorphous silicon film 2, its conductivity is declined and a photoconductive film with an increased resistance is obtained. With this constitution, the unevenness of the sensitivity can be eliminated without providing an external corrective circuit and the like.

IPC: H01L21/822
Filed: 1983-07-26
Abstract: PURPOSE:To improve the controllability of thickness of a Ta2O5 as well as to obtain the capacitor of high capacity density and low leak current by a method wherein an Si3N4 ultrathin film is formed on an Si substrate, and then a low N-impurity density and a high N-impurity density Ta2O5 are coated successively. CONSTITUTION:A heat treatment is performed on the N type Si substrate 1 at 1,200 deg.C for 1hr in 100% NH3, and an Si3N4 superthin film 2 of approximately 30Angstrom  is formed thereon. Subsequently, at first a Ta2O5 film 3 of 300Angstrom  containing N2 is coated in Ar+ O2 by performing an RF sputtering method using Ta2O5 as a target electrode, and while maintaining the above sputtering condition, a Ta2O5 film 4 of 200Angstrom  containing high density of N2 is superposed by introducing N2 in Ar+O2. As a result, the density of N2 is high in the vicinity of surface 6 and it is gradually lowered in the direction of the interface of the films 2 and 5. Also, the Ta2O5 film 3 having high N-density is highly densed in structure, the contamination coming from outside can be prevented, and the leak current of the Ta2O5 film can also be reduced. An Al electrode 8 is attached, a heat treatment is performed at 400 deg.C for approximately 10min and the device is completed. As an ultrathin film 3 is used, the capacity is changed even when a heat treatment period is made longer, no Ta silicide is generated, and the capacitor having low leakage can be obtained.

Title: Method for removing nox and equipment therefor
Inventor: IKEDA TETSUYA
IPC: B01D53/56
Filed: 1991-06-07
Abstract: PURPOSE:To make NOX undergo decomposition removal reaction at room temp. by making NOX-containing gas come into contact with an adsorbent to adsorb NOX and irradiating microwave on the adsorbent. CONSTITUTION:NOX-containing combustion flue gas is set at an arbitrary flow by a gas flow controller 1 and uniformly mixed with N2, O2, CO2, CO, ete., in a gas mixer 2 and enters cylindrical metal column 3. A testing gas leaving the column 3 is introduced into a NOX analyzer 4 for reactional products analysis. Microwave is generated from an oscillator 5 and irradiated on zeolite 8 in the column 3 from an opening 7 of the column 3 through a transmittal waveguide 6. At this time, microwave energy is absorbed by water molecules and NOX molecules in the micropore of the zeolite to excite the movement of the adsorbed molecules. Thereby the activation energy of NOX-thermal decomposition reaction in the micropore can be lowered, causing the reaction to occur without putting at high temperature.
