Abstract: Provided is a separation and recovery apparatus for continuously separating and recovering, from a resin mixture containing a resin containing a hydrolyzable polymer and a resin containing a nonhydrolyzable polymer, a hydrolytic component a of the hydrolyzable polymer A and the nonhydrolyzable polymer B, the apparatus including: a crushing unit that crushes the resin mixture a melting/discharging unit that melts a crushed product obtained by the crushing unit to form a fluid and discharges the fluid at a high pressure; and a hydrothermal reaction treatment unit that continuously subjects the fluid discharged from the melting/discharging unit to a hydrothermal reaction treatment, wherein, in the melting/discharging unit, the hydrolyzable polymer A is hydrolyzed, and the hydrolytic component a thereof is dissolved and transferred into water permeating a sintered alloy diaphragm, thereby separating the nonhydrolyzable polymer B.

Abstract: According to one embodiments, a wearing detection apparatus includes a restraint device, an imaging device, a control unit, and an output device. The restraint device is to restrain a passenger seated in a seat, and includes a strap an exposed area of which changes when the strap is being worn and not worn. The imaging device captures an image of the restraint device including the strap. The control unit detects from the image captured by the imaging device, a recognition image corresponding to a recognition member provided in an area that is exposed when the strap is worn. The output device outputs a result of detection of the recognition image.
