Disclosed is an observable centrifugal apparatus capable of checking in real time a state of a sample during reaction of separation or synthesization in the form of a stable and high-quality image at a high frame rate. An observable centrifugal apparatus A has a rotary disc 4 rotating about a rotary shaft 2, a reactor 6 disposed on the rotary disc and rotating together with the rotary disc while accommodating a sample, and a microscope 8 for observing a state of the sample within the reactor, in which predetermined substances of the sample are separated or synthesized by applying a centrifugal force to the sample within the reactor. The microscope is fixed in a predetermined position on the rotary disc so as to enable the state of the sample within the reactor to be observed, and the rotary disc is fitted with an imaging device 19 for photographing the state of the sample, caught by the microscope, within the reactor and a microscope image, and with an image wireless transmission device 12 for wirelessly transmitting in real time the photographed image of the microscope image photographed by the imaging device as a dynamic image.
摘要:
A heating and pressurizing apparatus (101), to which a circuit board (70) with electronic components (8) pre-bonded thereto via bonding elements (9) is carried in, is provided. The heating and pressurizing apparatus post-bonds the electronic component to the circuit board by heating and pressurizing the electronic component by a contact member (1211) having a heating device (122). By executing the pre-bonding and the post-bonding of the electronic components to the circuit board independently of each other, the time required for the post-bonding can be reduced, compared with the conventional case, and the productivity of the whole mounting line can be improved.

When a control section (39) turns on a switch (31, 33, 35), a capacitor (37) is connected to a secondary battery (B1) in parallel. Accordingly, voltage between both ends of each capacitor (37, 38) reaches voltage between both polarities of each secondary battery (B1, B2). Thereafter, when the control section (39) turns off the switch (31, 33, 35) and turns on a switch (32, 34, 36), each capacitor (37, 38) is connected to the secondary battery (B2, B3) in parallel. The capacitor (37, 38) is charged/discharged to balance voltage between both polarities of the secondary battery (B1 to B3).
