    • In a continuous casting process for steel, a molten core inside a strand is stalled at a specific point Q in a pass line of the strand to form a cored portion including no molten steel in the strand downstream of the specific point Q, and the cored portion is rolled by a pair of rolls under pressing into a solid strand in the latter half of a strand drawing stroke. The resulting solid strand comprises a skin formed of a chill crystal and the interior formed of a columnar crystal by addition of proper casting temperature. A through continuous casting/rolling process in which the above improved continuous casting process is combined with a subsequent hot rolling process is also disclosed. A drastic increase in the casting efficiency, an improvement in quality, and an equipment capable of freely adjusting a casting thickness can be resulted so that direct coupling between continuous casting and rolling is achieved and near-net-shaping of various steel materials is promoted.
    • 在钢的连续铸造工艺中,股线内的熔融芯在线的通过线中的特定点Q处停止,以形成在特定点Q下游的线中不包含钢水的芯部, 在拉丝笔的后半部分中,通过一对辊压制成实心线。 得到的固体链包含由冷却晶体形成的皮肤,并且通过添加适当的浇铸温度由柱状晶体形成的内部。 还公开了将上述改进的连续铸造工艺与随后的热轧工艺组合的贯穿连续铸造/轧制方法。 可以实现铸造效率的大幅提高,质量的提高,能够自由调整铸造厚度的设备,从而实现连续铸造和轧制之间的直接耦合,促进各种钢材的近净成形。

    • Apparatus for fixing toner image on a toner image supporting member in electrophotographic copying machine is disclosed. The fixing apparatus includes three rotary rollers which are in contact with each other under the action of pressing means. One of the three rollers has a smaller diameter than the other two rollers. Two rollers with which the toner image supporting member comes into contact are disposed in such a manner that the axes of the two rollers intersect each other and the portion at which the two rollers contact each other or are closest to each other forms a straight line relative to the direction of roller axis. According to one embodiment of the invention, the remaining one roller with which the supporting member does not contact, is formed as a crown roller, that is, a roller which has its largest diameter at the middle portion of the roller.
    • 公开了一种用于将调色剂图像定影在电子照相复印机中的调色剂图像支持部件上的装置。 定影装置包括在压制装置的作用下彼此接触的三个旋转辊。 三个辊中的一个具有比其他两个辊更小的直径。 调色剂图像支撑部件接触的两个辊以这样的方式设置,使得两个辊的轴彼此相交,并且两个辊彼此接触或彼此最接近的部分形成直线相对 到辊轴方向。 根据本发明的一个实施例,支撑构件不与其接触的剩余的一个辊形成为冠辊,即在辊的中间部分具有最大直径的辊。
