Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a mass storage device proportional to the time constant and to execute linear acceleration/deceleration control at a long time constant even in a small control system by outputting command speed obtained in a series of specified processes when there is a difference between feed speed outputted this time and command speed outputted at previous time. SOLUTION: A value obtained by subtracting present DRP from DRP which is to be given when a deviation between an inputted feed distance and the outputted command distance is acceleration/deceleration-processed with the conditions of a droop DRP, feed speed F and the time constant Tc and when it becomes constant speed is set to be a droop value coDRP. When inputted feed speed F is the same value as command speed FDT which is outputted at previous time, it is outputted as it is (S17). When they are not same, (during acceleration or deceleration), coDRP is calculated (S13). Then, the number X of processing times is calculated and the lacked value coFDT of command speed FDT is calculated for inputted feed speed F. Then, command speed FDT and DRP are calculated based on coFDT (S16).

Abstract: PURPOSE:To sample a proper amount of sample on the optimum condition from a container of a fluid contents other than a reaction processing tank by communicating a capsule with a vacuum source with the advance of a piston internally contacting a cylinder while with the container with the retraction thereof. CONSTITUTION:The mouth section of a capsule 4 is inserted into a sample withdrawing port 5 and retained airtight combined together and then, a piston 8 is advanced to have the sample withdrawing port 5 communicating with a connection port 6 through an vent path 10 when a communicating port 3 with a container 1 is closed with the tip thereof. As a result, the capsule 4 can communicate with a vacuum source and is reduced negative in the pressure to eliminate the infiltration of outside air through elastic rings 7 and 9. As the piston 8 is retracted to open the communicating port 3 between the container 1 and a cylinder 2, with the traction of the vent path 10, the communication between the sample withdrawal port 5 and the connection port 6 is cut off while the sample withdrawal port 5 communicates with the container 1 through the communicating port 3. Therefore, depending on the negative pressure in the capsule 4, the fluid contents in the container 1 are sucked and stored into the capsule 4 as sample.
