Abstract: Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.

Abstract: Provided are a solvent separation method, a solvent separation apparatus, and a solvent separation system that make it possible to easily collect a solvent removed from an exhaust atmosphere and that make it possible to easily carry out maintenance of exhaust gas pathways. An impeller placed in a storage space of a casing is rotated to introduce a gas including a volatilized solvent from an inlet of the casing into the storage space, and the volatilized solvent is cooled and devolatilized by a collection face that has been cooled so as to have a surface temperature lower than the temperature of the gas, to thereby separate the solvent from the gas.

Abstract: An endoscope having an insertion portion to be inserted into an object to be observed, includes: a substantially tubular holder member mounted to the insertion portion and having an open front end portion including a shoulder surface surrounded by an axial wall; a lens barrel holding an objective lens system and received in the holder member; and a light-transmissive closure member fitted into a front opening defined by the axial wall, and fixed to the front opening by a bonding agent interposed between an outer circumferential surface of the closure member and an opposing inner circumferential surface of the open front end portion of the holder member, wherein a space axially adjoining the shoulder surface is defined between an outer circumferential surface of a front end portion of the lens barrel and an opposing inner circumferential surface of the holder member.
