Abstract: A pore forming method in which a pore is formed in such a way that a first voltage is applied between electrodes that are disposed with a film in an electrolytic solution therebetween; a second voltage, which is lower than the first voltage, is applied between the electrodes; a current that flows between the electrodes owing to the application of the second voltage is measured; it is judged whether a value of a current is equal to or larger than a predefined threshold; and if the value of the current is smaller than the threshold, the above sequence is repeated until a pore is formed. In this case, the second voltage is a voltage that makes the value (IPF) of the current flowing through the film practically 0. With the use of the above method, a nanopore is formed in the film simply, easily, and accurately.

Abstract: A welding gun includes a driving-force transmission mechanism which converts linear displacement of an output unit of a driving unit into rotational displacement of a clamping arm. The driving-force transmission mechanism includes: an inclined part which is integrally displaced with the linear displacement of the output unit, and which is inclined with respect to the displacement direction of the output unit; and a part to be pressed which is pressed by the inclined part. The clamping arm rotates in accordance with movement of the part to be pressed which is pressed by the displaced inclined part, and generates clamping force.

Abstract: A first modulation voltage is applied to a thin film. An amount of a change in the phase of a current carried through the thin film with respect to the phase of the first modulation voltage is compared with a threshold. Upon detecting that the amount of the change in the phase exceeds the threshold is detected, the application of the first modulation voltage is stopped. Thus, a nanopore is formed on the thin film at high speed.
