Abstract: An exercise bicycle for exercising the arms and the legs or for exercising the arms independently of the legs is provided wherein a pedal shaft supporting pedal cranks for transmitting motion of the legs is transmitted to an intermediate shaft through a one-way clutch. The intermediate shaft, handle bars and a flywheel are connected to one another. Further, a load applying device is provided as a braking structure which makes use of eddy currents of magnets so as to minimize an initial resistance at the start of exercise and to increase the braking load as the rotational speed of the wheel increases.

Abstract: A process for continuously casting thin slabs, which comprises the steps of pouring a molten metal from a large-sized tundish through a sliding nozzle into a small-sized tundish, over-flowing the molten metal from the small-sized tundish to pour the molten metal into a continuous casting machine of the twin-belt type is disclosed. According to the process, a pouring rate into the small-sized tundish is calculated prior to overflow on the basis of a change in weight of the small-sized tundish and the degree of opening of the sliding nozzle is adjusted so as to make the calculated pouring rate come close to the target pouring rate into the small-sized tundish or into the casting machine.
