A combustion heater (110) provided with a heating plate (126); a placement plate (120) disposed opposite the heating plate; an outer wall (122) provided around the outer circumference of the heating plate and the placement plate; a partitioning plate (124) that is disposed opposite the heating plate and the placement plate inside a space enclosed by the heating plate, the placement plate, and the outer wall, that forms a lead-in portion (134) by a gap with the placement plate, and that forms a lead-out portion (138) by a gap with the heating plate; and a combustion chamber (136) that is arranged in the space enclosed by the heating plate, the placement plate and the outer wall, and at which the fuel gas that was introduced from the lead-in portion combusts, and that leads out exhaust gas produced by the combustion toward the lead-out portion; in which a concavo-convex portion (146) that has concavities and convexities in the thickness direction is provided in the partitioning plate.

A chimney has a lower portion substantially in the shape of a pyramid and an upper portion forming a cylindrical portion that extends with a predetermined dimension upwardly and is provided in a ceiling portion of a building of a coil yard that is used for temporary storage of the hot-rolled coil which is an intermediate iron and steel product acting as a high-temperature heat radiator that is manufactured using the hot-rolling equipment of an iron and steel mill. A power generating turbine is provided at a predetermined position in the cylindrical portion. An intake duct is provided on a lower end portion of the side walls of the building. Hot-rolled coils that are in a high-temperature condition after manufacture are successively imported into the coil yard and accumulated and stored until transfer to a subsequent processing step. An ascending airflow is generated by sequential heating of air introduced into the building from the intake duct using heat retained in the hot-rolled coils. The power generating turbines are rotated by the ascending airflow passing through the cylindrical portion of the chimney to thereby execute wind power generation. As a result, the heat retained in the high-temperature heat radiator manufactured by introduction of heat can be efficiently used.

A metal strip casting apparatus and method of casting metal strip include assembling a pair of counter-rotatable casting rolls positioned laterally forming a nip between for casting, and assembling a pair of brush rolls, each of the brush rolls associated with one of each of the casting rolls. Each brush roll includes at least one spaced apart brush line extending substantially along the axial length of the casting roll. The brush lines may form a spiral, zigzag, wave or crisscross array about the brush roll. The brush roll may include one or more staggered rings with regularly or irregularly spaced apart bristles which form the brush lines. The brush lines may be between 10 to 50 mm apart and separated by between 2 mm to 45 mm of open space. The brush lines may be one line per 10 mm to 90 mm of axial length of brush roll.

A cooling system for a vacuum processing apparatus is provided with an internal heat conduction path for transfer of heat entering the subject body through the vacuum processing apparatus, a heat radiation path for radiation of the heat to an outside of the vacuum processing apparatus and a heat conduction path for regulation of quantity of heat transfer between the internal heat conduction path and the heat radiation path. Preferably, a heat pipe is applied to the internal heat conduction path.

摘要:
The inside of the collision cell 20 placed in the analysis chamber 10 which is vacuum-evacuated is partitioned into an anterior chamber 23 and a posterior chamber 24 by the partition wall 21 with a communicating aperture 22. The former is used as a dissociation area A1 and the latter as a convergence area A2. Electrodes 27 and 28 for forming a radio-frequency electric field are placed in the chambers 23 and 24, respectively. When a CID gas is supplied into the anterior chamber 23, the CID gas is dispersed inside the anterior chamber 23 and flows into the analysis chamber 10 via the posterior chamber 24. Consequently, the gas pressure in the posterior chamber becomes higher than the gas pressure in the analysis chamber 10, and the gas pressure in the anterior chamber 23 becomes higher than the gas pressure in the posterior chamber 24. Hence, the optimum gas pressure for the precursor ion's dissociation and the ions' convergence by a cooling process can be realized in each of the dissociation area A1 and the convergence area A2. Therefore, it is possible to increase both the efficiency of dissociation and the efficiency of the ion convergence.
