And it is connected via an interface unit (not shown) as required. Further, the CPU 91 has a similar configuration and a rotation sensor 96 that detects at least one of the rotational speeds of the revolution body 20 and the rotation body 30 and a display unit 97 that displays the state of the centrifuge 1 and the like for the user. And are connected.

  The CPU 91 issues an instruction to the drive control unit 92 based on the operating conditions of the centrifuge 1 input from the user via the operation unit 95, information from the detection unit 94, the rotation sensor 96, and the like, and centrifuges for the user. Information indicating the state of the machine 1 is displayed on the display unit 97. The CPU 91 may include a storage unit (not shown) and store temperature information of the material M to be processed by the detection unit 94, preset operating conditions of the centrifuge 1, and the like.

  The drive control unit 92 controls the operation of the drive unit 50 based on an instruction from the CPU 91. For example, when an induction motor is adopted as the motor 51, the drive control unit 92 supplies the motor 51 with AC power whose frequency is determined so that the rotation speed of the revolution body 20 instructed by the CPU 91 can be realized.

  As shown in FIG. 1, the detection unit 94 is attached to the inner bottom of the hollow portion of the rotation body 30 of the rotation body 30, and at least the temperature of the storage container 40 and the material M to be processed stored in the storage container 40.

Alternatively, as the material to be processed M, it is possible to apply a fluid to be subjected to an emulsification process.

(3) Transmission / reception by the first transmission / reception unit 70 and the second transmission / reception unit 80 Transmission / reception is performed between the first transmission / reception unit 70 and the second transmission / reception unit 80. Below, the mechanism of this transmission / reception is demonstrated.

  As shown in FIG. 4, a detection unit 94 is connected to the first transmission / reception unit 70. In addition, as shown in FIG. 4, the second transmitting / receiving unit 80 is connected to a power supply unit 82 provided outside the revolution body 20 and arranged inside the centrifuge 1 or outside the centrifuge 1. The power supply unit 82 is configured to generate AC power and supply it to the second transmitting / receiving unit 80.

  Here, the 1st transmission / reception part 70 is comprised by the coil body provided so that the autorotation body main body 32 of the autorotation body 30 might be externally fitted as demonstrated above. On the other hand, the second transmission / reception unit 80 is fixed to the partition body 60 and arranged so that the separation distance α from the first transmission / reception unit 70 is kept constant regardless of the rotational positions of the revolution body 20 and the rotation body 30. It is comprised by the made coil body.

  For this reason, the AC power is supplied from the power supply unit 82 to the second transmission / reception unit 80, so that the first transmission / reception unit 70 is electromagnetically induced regardless of whether the revolution body 20 and the rotation body 30 are rotating. Electric power is generated. That is, transmission / reception is performed between the first transmission / reception unit 70 and the second transmission / reception unit 80.

  The power generated in the first transmission / reception unit 70 is supplied to the detection unit 94 connected to the first transmission / reception unit 70. Thereby, the detection unit 94 becomes operable.

  In order to perform transmission / reception between the first transmission / reception unit 70 and the second transmission / reception unit 80, the distance α between them must be a predetermined value. If the separation distance α is wide, transmission / reception becomes difficult. On the other hand, if the separation distance α is narrow, the first transmission / reception unit 70 and the second transmission / reception unit 80 may come into contact with each other while the revolution body 20 and the rotation body 30 are rotating. Produce.

  Based on the above, the separation distance α between the first transmission / reception unit 70 and the second transmission / reception unit 80 is determined on condition that necessary transmission / reception can be performed between them and that no contact occurs between them. do it. Note that the specific separation distance α can be obtained by simulation or experiment.

First, in the centrifuge 1, the storage container 40 in which the material to be processed M is stored is attached to the rotation body main body 32 of the rotation body 30 by the user.

  Subsequently, in the centrifuge 1, the operation of the centrifuge 1 is started based on an operation condition set by a user input via the operation unit 95 or temperature information detected by the detection unit 94. That is, the CPU 91 gives an instruction to the drive control unit 92 based on the operation condition.

  The drive control unit 92 controls the motor 51 of the drive unit 50 in order to realize the rotational speed of the revolution body 20 instructed by the CPU 91. Thereby, since the storage container 40 revolves around the rotation axis L2 while revolving around the revolution axis L1, the material M is processed.

Subsequently, in the centrifuge 1, after a predetermined time has elapsed, the CPU 91 instructs the drive control unit 92 to stop the drive unit 50.
Thus, the processing of the material to be processed M by the centrifuge 1 is completed.

Can supply power.

  In the centrifuge 1, the separation distance α is constant regardless of the rotational positions of the revolution body 20 and the rotation body 30. Thereby, in the centrifuge 1, transmission / reception between the first transmission / reception unit 70 and the second transmission / reception unit 80 which is always stable can be realized. As a result, power supply from the power supply unit 82 to the detection unit 94 is stabilized. it can.

  Moreover, in the centrifuge 1, the 1st transmission / reception part 70 and the 2nd transmission / reception part 80 are comprised by the coil body, and transmission / reception between them is performed using electromagnetic induction.

For example, in the centrifuge 1, the second transmitting / receiving unit 80 may be a light emitting element (for example, a light emitting diode), and the first transmitting / receiving unit 70 may be a light receiving element (for example, a solar cell). In this case, in the centrifuge 1, the second device 130 supplies power to the second transmission / reception unit 80 to emit light, the first transmission / reception unit 70 receives light to generate power, and supplies power to the first device 120.

Therefore, this centrifuge enables transmission / reception between the outside of the revolution body and the rotation body regardless of whether the revolution body and the rotation body are rotating.
In the present application, the “distance between the first transmission / reception unit and the second transmission / reception unit” means a distance between points that are closest to each other. In addition, the concept of “constant separation distance” is not only strictly constant, but also when fluctuation occurs in a range that does not cause substantial influence, that is, “separation distance is substantially constant”. This includes cases where
