Abstract: PURPOSE:To remarkably shorten the time required for filling, and to improve the workability by allowing inert gas which does not react to a core chip base material, to flow under a gap and setting the inside of the gap to a negative pressure state, and sucking and filling molten glass into the gap. CONSTITUTION:As for a first and second core chip base materials 6, 7, the respective inside surfaces are aligned and butted by forming a prescribed interval, usually, a gap G of about 10mum, and a glass rod 8 is placed in the upper part of the gap G. Thereafter, at the time of heating and melting the glass rod 8, gas which does not react to the core chip base material 6, 7 is allowed to flow, for instance, in the direction orthogonal to the longitudinal direction of the gap G, along the lower part of the gap G, namely, the lower face of the first and second core chip base materials 6, 7. By following it up, air in the gap G flows out to the outside. The inside of the gap G becomes a negative pressure state, and a suction force works on the glass 8 in the direction of the lower part of the gap G. By said suction force, a flow speed of molten glass 8' becomes high and the time required for filling is shortened remarkably.

Abstract: PROBLEM TO BE SOLVED: To prevent contamination of a paper feeding roll and to obtain stable printing quality for a long time by providing a device with a paper feeding roll having a surface layer comprising a conductive material having specified volume resistance, and with a cleaning member for the paper feeding roll in such a manner that the cleaning member consists of a material which is electrified into the opposite polarity to the polarity of the toner particles depositing on the paper feeding roll. SOLUTION: A toner 6 before fixed is electrified into about +30 μC/g charges by an electrifying device 14, and thereby, deposition of the toner on the paper feeding roll 11 is suppressed to a certain degree. Most of the toner 15 depositing on the paper feeding roll 11 has positive polarity. Therefore, rayon which is easily charged into negative by triboelectrification is used for the cleaning brush 12 as a cleaning member for the paper feeding roll. Even when the surface of the paper feeding roll 11 is coated with a material essentially comprising PVDF(polyvinylidene fluoride) or nylon having the volume resistance controlled to 10<7> to 10<11> Ω.cm a rayon cleaning brush 12 is effective.

Abstract: PURPOSE:To improve durability by improving emission of exhaust gas through promotion of activation of a catalyst and suppression of the increase of the temp of the catalyst and the occurrent of deterioration thereof. CONSTITUTION:Catalysts 16a and 16b are independently arranged at each of single banks LB and RB in a state to approach the exhaust gas port 2b of each bank. When the temperatures of the catalysts 16a and 16b are low, bypass passages 17 and 18 are closed by means of switching valves 19a and 19b. By guiding exhaust gas to the catalysts 6a and 16b right on the downstream side, activation of the catalysts 16a and 16b is promoted by means of an exhaust gas heat and emission of exhaust gas is improved. Meanwhile, when the temperatures of the catalysts 16a and 16b are high, the bypass passages 17 and 18 are opened by means of the switching valves 19a and 19b and exhaust gas is guided through the exhaust gas ports 2b of banks LB and RB to the catalysts 16b and 16a on the other banks RB and LB through the bypass passages 17 and 18. Since exhaust gas is cooled during the flow of it through the bypass passages 17 and 18, the increase of the temperatures of the catalysts 16a and 16b and deterioration and the damage thereof are suppressed and durability is improved.
