Title: Removal of oxygen
Inventor: TAMAURA YUTAKA
IPC: B01D53/46
Filed: 1990-04-04
Abstract: PURPOSE:To decompose exhaust gas while magnetite is continuously activated by sending the exhaust gas containing oxygen, carbon monoxide and nitrogen oxide into a reaction chamber having magnetite of predetermined temp. received therein. CONSTITUTION:A reaction chamber 3 is connected to the passage of the exhaust gas containing oxygen, carbon monoxide and nitrogen oxide from a diesel engine. The reaction chamber 3 is packed with magnetite 2 of an appropriate form and heated by a heater 1 so that the internal temp. thereof becomes about 300 deg.C. When the exhaust gas is sent into the reaction chamber 3 having magnetite 2 heated to about 300-600 deg.C received therein, oxygen can be removed. That is, oxygen in the exhaust gas is continuously removed and nitrogen oxide is efficiently decomposed to nitrogen gas and carbon dioxide can be decomposed in a post process by activated magnetite.

Title: Nuclear magnetic resonance imaging system
IPC: G01R33/28
Filed: 1992-03-18
Abstract: PURPOSE:To eliminate the detect of an FIR system by adoption of an IIR system and to eliminate the defect of the nonlinearity of phase rotation as well by constituting a digital filter means which combines a digital filter of a digital signal processing system of an AD conversion section with a recurrence type filter so as not to generate the phase rotation of signals. CONSTITUTION:The signals are subjected to such processing that the absolute value of the frequency characteristics of the phases is the same value and the codes are inverted after the filter processing by the FIR system. This processing is executed twice and the data input of the second time is versed in time serial sequence from the first time. As a result, the rotation of the phase is obviated and an increase in computation quantity is suppressed, by which the decrease of the processing speed is prevented. The filter processing of the data is, therefore, executed at a high speed without disturbing the phase information of the important signals in the MR imaging.

Abstract: PURPOSE:To reduce the frequency of replacement by making a target material in a band form to wind it up in a desired direction, and by moving the material prependicular to the winding direction. CONSTITUTION:A band-shaped target 1 wound up on a reel 2 is continuously rewound on a reel 3 by the driving of a motor 5. When the target 1 passes between press plates 9 and 10, a laser beam 8 passing a slit 9a is radiated on the target 1 and a plasma is formed, generating an x-ray. When the target is rewound up on the reel 3, it is moved in a direction S by a moving means 7. The target 1 is rewound up from the reels 3 to 2 by the driving of a motor 4, and a plasma is formed by being irradiated with the light 8 and an x-ray is generated. This process is repeated until the width of the target 1 is used up. Since the device can be used for a long time while the target 1 is installed in an x-ray source, the number of replacement of target materials can be reduced.
