Abstract: In order to provide a piston and a syringe with good sliding performance and pressure resistance performance, the piston contained in the syringe that pressurizes or decompresses an internal medium is configured such that a soft portion made of a soft material and a rigid portion made of a material having rigidity higher than rigidity of the soft portion, are connected in series, and arranged such that the soft portion is in contact with the medium and the rigid portion is not in contact with the medium. The soft portion includes a hollow on a surface in contact with the medium. The rigid portion has an end surface facing the soft portion, the end surface including at least an outer peripheral portion in contact with the soft portion. The outer diameter of the soft portion is larger than the outer diameter of the rigid portion, and the outer diameter of the rigid portion is slightly smaller than the inner diameter of an outer cylinder of the syringe.

Abstract: A laser beam 6 irradiated from a side face of a microchip 1 in which plural channels 2 fill ed with a member of a refractive index n2 in an inner portion of a member of a refractive index n1 (n2 lower base, and is deviated swiftly from a channel array. Hence, the laser beam 6 is made to be deviated gradually from the channel array by irradiating the laser beam 6 from the side face of the microchip 1 by being inclined relative to the same plane in a direction of being directed from the lower base to the upper base. As a result, a larger number of the channels 2 can efficiently be subjected to laser beam irradiation.

Abstract: The objective of the present invention is to simply perform image observation through transmitted charged particles. A sample irradiated by a charged particle beam is disposed directly or via a predetermined member on a light-emitting element (23) whereinto charged particles that have traversed or scattered inside the sample enter, causing a light to be emitted therefrom, which is collected and detected efficiently using a light transmission means (203) to generate a transmission charged particle image of the sample.
