摘要:
A method for controlling an air servo cylinder apparatus includes an advancing process of advancing a piston up to a target position by controlling, by a controller, servo valves individually connected to a pressure chamber on the head side and that on the rod side of the cylinder, and a pressurizing process of subsequently applying a required pressurizing force to the piston. In the advancing process, the piston starts to be driven with the servo valve on the head side opened to the air intake side and the servo valve on the rod side opened to the exhaust side. Thereafter, the opening degree of the servo valve on the rod side is varied into an opening degree in accordance with a deviation of the current position from the target position, and thereby the piston is smoothly decelerated as it approaches the target position.

In an air servo cylinder formed by integrally combining an air cylinder, servo valves, and a controller via a manifold block, there are provided, in the manifold block, air discharge flow paths for releasing, to the outside, compressed air discharged associated with operations of the servo valves. In each of the air discharge flow paths, a silencer for reducing exhaust noise is incorporated so as not to protrude from the manifold block to the outside.

A reconfigurable operation apparatus includes a reconfigurable circuit, a storage unit and a control unit. The reconfigurable circuit has a plurality of small circuits and reconfigures a circuit using the small circuit selected from the plurality of small circuits based on recorded circuit information. The storage unit stores first and second circuit information which corresponds to first and second compression circuits, respectively. The control unit reconfigures the reconfigurable circuit into the first or second compression circuit by recording the first or second circuit information in the reconfigurable circuit in accordance with an input data string.

An analysis apparatus is an apparatus that performs electrophoresis using a microchip provided with a channel. The analysis apparatus includes a cooling unit (an electron cooling element and a driving circuit) that cools the microchip, a voltage application unit (electrodes and a power supply circuit) that applies voltage to a buffer solution filled in the channel of the microchip, an optical analysis unit (a light source, a light receiving element, and an analysis unit) that conducts, through the microchip, optical analysis of a sample introduced in the channel, and a control unit that controls the cooling unit, the voltage application unit, and the optical analysis unit. The control unit causes the cooling unit to start cooling the microchip, and after the microchip has been cooled, causes the voltage application unit and the optical analysis unit to operate.
