Abstract: A terahertz wave generator 1 includes a nonlinear crystal 4, which is capable of generating a terahertz wave TH, a pumping beam emitter 2, which emits a pumping beam L1, a seed beam emitter 3, which is disposed so as to be parallel to a nonlinear crystal 4 and emits a seed beam L2, a first total reflection mirror 17 and a second total reflection mirror 18, which successively reflect the seed beam L2 emitted from the seed beam emitter 3 to cause the seed beam L2 to be incident on the nonlinear crystal 4, and a convex lens 6, which collects the seed beam L2.

Abstract: A liquid containing exosomes is filtered through a first filter that has a hole diameter that passes the exosomes and blocks cells, and is then stored in a first storage unit (rough filtration step). Next, pressure is applied to the inside of the first storage unit to pump the liquid to a pre-filtration chamber in a second filter that blocks the exosomes so that water in the liquid is filtered out into a post-filtration chamber. The exosome-containing liquid that was not filtered out is returned to the first storage unit, thereby increasing the exosome concentration in the liquid for extraction (concentration step). The exosome-containing concentrate in the first storage unit is then filtered through a third filter having a hole diameter that passes the exosomes and blocks bacteria, and is sent to a recovery unit (sterilization filtration step).

Abstract: A pumping beam L1 enters from a pumping beam projector 3 into one end surface 2a of a nonlinear crystal 2, the pumping beam L1 and idler wave L2 are generated from another end surface 2b of the nonlinear crystal 2. The pumping beam L1 emitted from the other end surface 2b of the nonlinear crystal 2 is reflected and re-enters as a pumping beam L′ into the other end surface 2b and the idler wave L2 generated from the other end surface 2b of the nonlinear crystal is reflected by the reflection optical system 6 and re-enters as a seed beam L2′ into the other end surface 2b. The idler wave L2 enters as the seed beam L2′ together with the pumping beam L1′ into the nonlinear crystal and thus a terahertz wave with a large output and including a plurality of wavelengths can be generated.

Abstract: A surface treatment method and a surface treatment device 2 for a resin vessel 1 forms a coating or performs surface modification on the surface of the resin vessel 1. In a sterilized environment as well as an environment with a pressure equal to or higher than the atmospheric pressure, a material for the coating or the surface modification is attached to at least one of an inner surface and an outer surface of the resin vessel 1, and the resin vessel 1, to which the material is attached, is irradiated with an electron beam to perform the coating or the surface modification. It is possible to form the coating or perform the surface modification on the resin vessel at a high speed.

Abstract: Weighing and filling apparatus for controlling filling device based on a container weight. A linear actuator for driving a drive shaft coupled to container support unit is included, a weight measuring unit determines the container weight from a detected height of the drive shaft detected by a height detecting unit and a drive signal of the linear actuator at the detected height. A first acceleration signal is calculated from a specified height of the container support unit set in advance and the height detected by the height detecting unit, a second acceleration signal is calculated from the container weight and an expected weight expected to be applied to the container support unit. The container support unit is kept at the specified height by a drive signal calculated from the first and second acceleration signals.

Abstract: A pumping beam L1 is caused to be incident on an end surface 4A of a nonlinear crystal 4, and a seed beam L2, the diameter of which is increased by a concave lens 6, is collected and adjusted into a collimated beam by a convex lens 7 and caused to be incident on the end surface 4A described above. The pumping beam L1 and the seed beam L2 are caused to be incident on the end surface 4A with the pumping beam L1 and the seed beam L2 superimposed on each other, whereby the nonlinear crystal 4 generates a terahertz wave TH.
