Abstract:
A cylindrical screw feeder main body, catalyst feeding portions for introducing a catalyst into the screw feeder main body, low hydrocarbon feeding portions for introducing a low hydrocarbon into the screw feeder main body as a raw material, a screw for conveying the catalyst and nanocarbon produced by pyrolysis of the low hydrocarbon in the feeder main body, a solid matter discharging portion for discharging the catalyst and the nanocarbon conveyed by the screw out of the screw feeder main body and a gas discharging portion for discharging the unreacted low hydrocarbon and hydrogen produced by the pyrolysis of the low hydrocarbon out of the screw feeder main body are provided. Nanocarbon grown with the catalyst as top with time is continuously discharged out of the screw feeder main body while unused catalyst is being fed thereto at the same amount as that of nanocarbon, allowing efficient continuous reaction.

A temperature measurement portion is capable of measuring a temperature of the air drawn by each piece of equipment. A detection portion is capable of measuring a flow speed of the air drawn by each piece of equipment. A control portion is configured to control the air-conditioning based on the measurement result of the temperature or the flow speed of the air drawn by each piece of equipment.
Abstract:
An image forming apparatus includes an image forming unit, a sheet feeding unit for feeding a sheet, a registration roller for transporting the sheet toward the image forming unit, a rotational member for transporting the sheet toward the registration roller, at least one detection member provided on an upstream side of the registration roller, and a sheet size detection unit configured to receive an output from the detection member. The rotational member is configured to continue rotation until transportation of the sheet is completed. The registration roller is configured to rotate when a predetermined waiting time period has elapsed since the detection member detects sheet arrival. The sheet size detection unit is configured to detect a size of the sheet using a time period from a time when the detection member detects the sheet arrival to a time when the detection member detects sheet passage.
Abstract:
In an automobile wheel, a surface-side flange is provided on an outer circumferential edge of a wheel disk. The surface-side flange includes: a surface-side annular circumferential portion on an aesthetic surface; and a back-side annular circumferential portion that is formed continuously with, and on the back side of, the surface-side annular circumferential portion and that is thinner than the surface-side annular circumferential portion. An inner circumferential end of the back-side annular circumferential portion of the surface-side flange and an opening end of a surface-side bead seat of a wheel rim are welded together all along their circumferences. The automobile wheel allows the back-side annular circumferential portion of the surface-side flange to bear a stress that acts on a weld area. This relaxes the stress concentration on the weld area.
Abstract:
In a reaction where a lower hydrocarbon is subjected to direct decomposition by using a catalyst to produce a functional nanocarbon and hydrogen, the lower hydrocarbon is subjected to the reaction in an coexistent gas comprising low concentration of oxidizing gas, reducing gas or a mixture thereof. The precursor of functional nanocarbon produced on the catalyst and amorphous carbon secondarily produced on the catalyst react with the coexistent gas so that being removed from the catalyst, making it possible to prevent the drop of conversion with time on stream due to the inhibition of the reaction by the precursor and by-product. In the case where the raw material of lower hydrocarbon is biogas, the coexistent gas can be easily contained in methane by lowering purification degree of methane. Further, hydrogen can be obtained as one of decomposition products of lower hydrocarbon thus can be contained in methane during the reaction.
Abstract:
A high-density magnetic recording medium uses a nonmetallic substrate, while still providing high in-plane magnetic anisotropy and remanent coercivity. Such a medium can be formed by depositing a seed layer on a textured surface of the nonmetallic substrate in a gas mixture containing oxygen or nitrogen and an inert gas, while controlling the oxygen concentration or nitrogen concentration, and subsequently exposing the surface of the seed layer to oxygen or nitrogen.
