Title: Carbon material for reducing nitrogen oxide and reducing method
Inventor: KOMATSUBARA KATSUNOBU
IPC: B01D53/94
Filed: 1984-04-13
Abstract: PURPOSE:To simplify an NOx removal process to a large extent by performing denitration without using a gaseous reducing agent, in an exhaust gas denitration method, by using an NOx reducing carbon material obtained by modifying a carbon material containing a nitrogen component with sulfuric acid. CONSTITUTION:As the stock material of an NOx reducing carbon material, a carbon material containing a nitrogen component such as a PAN type activated carbon fiber is used. An aqueous sulfuric acid solution is prepared so as to bring the quantity of sulfuric acid to the stock carbon material to 20pts.wt. or more and the activated carbon material is immersed in said aqueous solution under stirring and, after moisture is removed by a rotary evaporator, the impregnated one is dried and receives heat treatment at 350-500 deg.C under an N2-stream. Activated carbon material thus prepared has an extremely high NOx reducing activity and lowers NOx reducing temp. to 100-300 deg.C.

Title: Optical sensing system
Inventor: KOSEKI TAKESHI
IPC: G01D5/26
Filed: 1981-05-20
Abstract: PURPOSE:To measure a change in resonance wavelength due to pressure through erasion of a zero point drift effect owing to temperature, by a method wherein polarized lights, crossing each other at right angles, are led to a photo resonator installed to a measuring point to measure a difference between resonance wavelengths produced due to polarization of the photo resonator. CONSTITUTION:A pressure P to be measured is applied through a process connection 17 to a pressure transducer 14 which employs a photo resonator 3 consisting of an optically isotropic medium, laser light from a wavelength sweep laser 12 is transmitted through an optical fiber 11, and is separated by a polarized light separator 13 into a photo wave, having an electric field component of the same direction 6 as that of a pressure P applied to the photo resonator 3, and a photo wave, having an electric field component of a direction 7 being perpendicular to the direction 6, to enter the pressure transducer 14. When attaining resonance wavelengths of their respective directions, a photo wave escapes from the resonator 3 through a polarized light separator 15, and a difference between the resonating wavelengths is counted by a counter 16. This erases the influence of temperature, which results in performing a measurement of pressure prevented from the occurrence of a zero point drift.

Title: Supply of constant amount of negative mixture powder
Inventor: IMAZAWA KAZUHIRO
IPC: H01M4/06
Filed: 1981-05-18
Abstract: PURPOSE:To supply a negative mixture powder into a negative case with high accuracy and reduced variation by preventing the electrostatic adhesion of the said mixture powder by carrying out arc discharge across an external discharge device, and a guide or a weighing equipment used for supplying the said negative mixture into a case. CONSTITUTION:In weighing and supplying a negative mixture 1, which is prepared by mixing an amalgamated zinc powder and a gelling-agent powder, into a negative case 3 of a battery, a discharge device 5 is installed outside the metallic weighing equipment of a supplying device. Then, arc is discharged from the device 5 toward a discharge electrode part 4 provided on a conical guide 2 or the like by using the device 5 as one electrode and using either both or part of the weighing equipment and the guide 2 as a counter electrode. By the means mentioned above, the electrostatic adhesion of the negative mixture 1 is prevented by discharging and removing static electricity, which is developed due to friction during the supply of the mixture powder 1. Consequently, the negative mixture powder 1 can be supplied with high accuracy, and a stable  battery with a reduced variation can be manufactured.

Abstract: PURPOSE: To produce a thin strip continuously and easily by conducting molten alloy to the surface of a rotary cooling body by means of electromagnetic force and quickly cooling the same.  
     CONSTITUTION: A raw material which is a base alloy is loaded into a melting furnace 1 and is melted, whereby molten alloy 4 is made. Thereupon, while a roll 5 is being cooled, it is rotated, while an electromagnetic pump 3 is operated. Then, thrust is given to the molten alloy 4 by the pump 3, and the molten alloy ascends along the slope of an ingate 6. In the top 7 of the ingate 6, it contacts with the surface of the roll 5 and is quickly cooled and solidified, thereby forming a wire or tape shape. The wire or tape separates from the roll 5. In this case, the quickly cooled and solidified material of desired thickness is obtained by suitably selecting the area where the molten metal 4 contacts with the roll 5, the velocity of flow of the molten metal, and the peripheral speed of the roll.

Abstract: PURPOSE:To unnecessitate the preparation of a fault diagnostic program due to a user himself, to easily apply the device even to an existent programmable system and to efficiently diagnose a fault without expanding the capacity of a memory for storing input/output patterns. CONSTITUTION:A fault diagnostic unit is connected to a system bus 1 of a PC. In the case of a teaching mode, based on setting due to an operation part 45, the fault diagnostic unit monitors the output pattern on the system bus 1 and stores the passage of time from a preceding change point of time to a change and the input/output pattern after the change in a storage part 42 each time the output pattern is changed. In the case of a diagnostic mode, the output pattern is similarly monitored, and it is judged whether that stored output pattern arrives within monitor time based on the passage of time of the output pattern or not. When that output pattern does not arrive, an unmatching part between the input/output pattern at that point of time and the input/output pattern stored in the teaching mode is displayed on a display part 44.
