Abstract: A method for treating exhaust gas includes: adsorbing target components in the exhaust gas with an adsorbent (5); introducing a nitrogen gas with an oxygen concentration of 10 vol % or less and a purity of 90 vol % or more into the adsorbent (5); and applying (6, 7, 8) nonthermal plasma to the adsorbent (5). After the adsorbent (5) adsorbs the target components in the exhaust gas, the nitrogen gas is introduced into the adsorbent (5), and then an electric discharge is generated so that the nonthermal plasma of the nitrogen gas is applied to the adsorbent (5) and causes desorption of the target components and regeneration of the adsorbent (5). This method can remove the target components effectively from oxygen-containing exhaust gas by using nitrogen gas plasma with high activity as a result of ionization of a nitrogen gas and combining adsorption, desorption by the nitrogen gas plasma, and nitrogen plasma treatment.

Abstract: An editing apparatus, and a bit rate control method and program are capable of converting a material bit rate of video material to a desired output bit rate without picture quality deterioration in a short time and simply. According to this invention, a bit rate determination unit 2 compares a material bit rate of entered video material S1 to be edited with an output bit rate. In a case where the output bit rate is larger than the material bit rate, the null data insertion unit 5 adds meaningless data to the material data of the video material to convert the material bit rate to the output bit rate. As a result, the material data of the video material S1 can be output without picture quality deterioration with the material bit rate converted to the output bit rate.

Abstract: An electromagnetic control valve has a passage for conducting fluid. An electromagnetic actuator generates an electromagnetic force. A main valve body opens and closes the passage in accordance with the electromagnetic force generated by the electromagnetic actuator. A bypass is formed in the main valve body. A sub valve body opens and closes the bypass in accordance with the electromagnetic force generated by the electromagnetic actuator. The electromagnetic force generated by the electromagnetic actuator is adjusted such that the sub valve body is opened and closed while the main valve body closes the passage.

Abstract: An apparatus electrochemically removes fine metal particles from an oil in water emulsion. The apparatus has a container for accommodating the emulsion. A supply port supplies the emulsion to the container. A plurality of cathode plates and anode plates are located in the container to face each other. The water in the emulsion is electrolyzed when a predetermined direct voltage is applied between the plates. The fine metal particles float with hydrogen generated by the electrolysis. Al(OH)3 attaches to H2 bubbles. A discharge port is located in a lower part of the container for discharging the emulsion from which the fine metal particles, sludge, oil and greese have been removed.

Abstract: A heat exchanger of the multi-flow type is provided with baffle members which are adapted to impart a zigzagging flow to the heat-exchange fluid in motion inside a flat tube and define, in conjunction with the inner wall of the flat tube, a flow path of a cross-sectional area having an equivalent diameter in the range of 0.4 to 1.5 mm. This heat exchanger excels in heat exchange ability and in facility of manufacture and assemblage.

Abstract: The present invention provides methods and apparatus for decomposing toxic compounds so that reaction by-products produced thereby are selectively reduced. A method generally comprises: introducing a carrier gas, having a toxic compound entrained therein, into a packed-bed of ferroelectric pellets; and polarizing the pellets to produce a plasma which decomposes the toxic compound. The pellets are coated with a catalyst selected to react with by-products of the decomposition of the toxic compound and thereby produce non-toxic compounds.
