Abstract: PROBLEM TO BE SOLVED: To stabilize the carrying of a paper sheet, for preventing an offset, to stably provide high image quality and to prolong a service life by providing a contact part between an extending roller and a roller having elasticity and obtaining an obtuse angle, as an angle formed by a line that links the axial centers of the extending roller and the roller having the elasticity and the surface of a belt extended between belt rotation supporting rollers on the upstream and downstream sides in a carrying direction. SOLUTION: The paper sheet on which an unfixed toner image is formed is carried along an intrusion guide 77 and intruded into a nip. At this time, an angle θa formed by the line that likes the axial centers of a driving roller 83 and a pressure roller 84 and the axial centers of a heating roller 82 and the driving roller 83 on which the fixing belt 81 is extended is the obtuse angle. Therefore an angle θ formed by the line that links the axial centers of the driving roller 83 and the pressure roller 84 and the fixing belt 81 on the upstream side in the carrying direction of the driving roller is the obtuse angle. Thus, the gap between the carried surface of the paper sheet and the fixing belt 81 is made larger, to prevent contact with the fixing belt 81, even if the paper is held in the nip.

Abstract: PURPOSE:To produce silicon carbide-based refractories very suitable for use as lining refractories especially for a blast furnace. CONSTITUTION:Stock consisting of, by weight, 60-80% SiC aggregate, 10-30% beta-Si3N4, 2-10% refractory clay, 1-10% metal Al and 3-6% metallic Si is embedded in breeze and fired at 1,500-1,650 deg.C in a nonoxidizing atmosphere in a tunnel kiln to produce the objective silicon carbide-based refractories much more excellent in alkali resistance than conventional silicon carbide-based refractories. Since firing is carried out at such a low temp. as 1,500-1,650 deg.C in the tunnel kiln, the objective refractories can be produced at a low cost corresponding to about 1/2 of the cost by the conventional nitriding reaction. Since the tunnel kiln is used, continuous firing is enabled and excellent mass productivity is ensured.

Abstract: PURPOSE:To large extend the measuring range to an oxygen partial pressure side by measuring the oxygen partial pressure by utilizing an electronic conduction. CONSTITUTION:For instance, a sensor element 1 of a probe 20 is provided in a pipe 21 through which gas to be measured of a high temperature of >=about 700 deg.C flows, and by operating a potentiostat 22, a prescribed voltage is applied so that a measuring pole 5 and a reference pole 6 go to a positive pole and a negative pole, respectively. In the first stage of applying the voltage, an ion current flows by oxygen which is contained in the reference pole 6 and a solid electrolyte 4 in the beginning, but since the reference electrode 6 is sealed from the external world, an electrode reaction of oxygen is not generated in the reference pole 6. Therefore, after this transient period has a elapsed, oxygen does not move, and a prescribed electronic current flows. A current value by an electronic conduction after this current value kept constant is read by an ammeter 23. Simultaneously, a temperature of the sensor element 1 is measured by a thermometer 24. By the current value by said electronic conduction and the measured value of a temperature, oxygen partial pressure is derived.
