摘要： An excavation technique for a stratum capable of excavating a submerged stratum such as a layer containing an underground resource by using laser irradiation in liquid is provided. In this technique, a laser beam transmitted through laser transmission means 20 is irradiated in liquid 90 in form of a laser beam having a wavelength with high absorptance of the liquid 90 by laser-induced bubble generation means 35, generating a bubble flow 36, thus excavation of a submerged stratum may be carried out by using a laser-induced destruction effect. Moreover, a laser beam 41 having low absorptance of the liquid 90 is irradiated by laser irradiation means 39 and passed through the bubble flow 36, thereby applying a thermal effect to a stratum to destroy rock and excavate the stratum. The destruction effect and the thermal effect also may be cooperatively worked.

摘要： A method for manufacturing a heat exchanger is provided. The heat exchanger includes a plurality of plate-like fins that are stacked with a predetermined fin pitch, and a plurality of flat heat exchanger tubes that are disposed with a predetermined spacing from one another along the longitudinal direction of the plate-like fins and extend through the plate-like fins along the stacking direction. The plate-like fins each have a plurality of notches provided in an end portion along the long side. The plate-like fins have a shape corresponding to the cross-sectional shape of the flat heat exchanger tubes, and the flat heat exchanger tubes are inserted into the notches. The manufacturing method includes disposing the flat heat exchanger tubes with a predetermined spacing from one another, and attaching the plate-like fins to the flat heat exchanger tubes one by one by inserting the flat heat exchanger tubes into the notches of each of the plate-like fins.
