Abstract: A recycle information management system includes a communication device and a management device. The communication device transmits recycle information acquired from a recycle system via a network. The recycle system includes at least a recycling device that removes at least oil from the collected refrigerant to recycle the refrigerant. The management device includes a storage unit that stores the recycle information in association with a recycle system ID usable to identify the recycle system.

Abstract: A suction method is provided as a method of performing, by using a suction collet, suction of a Fabry-Perot interference filter including a substrate and a laminated structure that is provided on the substrate and that includes a main surface facing the side opposite to the substrate, the method including a first step of arranging the suction collet so as to face the main surface, a second step of bringing the suction collet into contact with the Fabry-Perot interference filter after the first step, and a third step of suctioning the Fabry-Perot interference filter by using the suction collet after the second step.
