きるということにある。Among conventional centrifuges of this type, those which do not have the delayed operation function have the operation time subtracted from the predetermined operation end time in order to end the operation at the predetermined time. There was a problem that the operation had to be started manually at the time. Further, in the case of having the delay operation function, there is a problem that it is necessary to calculate the delay time so that the operation is started at a time when the operation time is subtracted from the desired operation stop time, which is a troublesome calculation. The object of the present invention is to set the operation time and the operation stop time (and the number of revolutions), and the centrifuge will automatically start the operation.
The end is that the troublesome calculation can be omitted and the driving operation can be simplified.

る。As another example, the flow chart shown in FIG.
I will explain according to G. First, the rotation speed N, the operating time T, and the operation stop time Tre are set. After setting, turn on the start switch. At the moment when the start switch is turned on, the current time Tr is counted, and it is determined whether the relation between the operation stop time Tre, the operation time T and the current time Tr is Tre-Tr ≧ T. Here, in the case of Yes, the process waits until the time of Tre-T, and at the time of Tre-T, the driving device 2 is accelerated and the centrifugal separation is performed at the rotation speed N. Then, the operation is stopped at the stop time Tre. In the case of No, it is not possible to finish the operation within the set operation stop time under the same operating conditions, so first find Ns from TN 2 = (Tre-Tr) Ns 2 , then allow Ns and the rotor. Rotation speed Nr is compared and Ns ≤ Nr
In the case of 1, the rotation speed is changed from N to Ns, the operation is started, the centrifugal separation is performed, and the operation is stopped at the set operation stop time Tre. If Ns> Nr, an alarm is issued and operation is disabled.
