Abstract: A congestion degree determination apparatus (2000) acquires a captured image (50) generated by an in-vehicle camera that captures an inside of a target vehicle. The congestion degree determination apparatus (2000) determines, for each of persons (30) present in the target vehicle, an area (20) in which the person (30) is positioned out of a plurality of areas (20) in the target vehicle using the captured image (50). The congestion degree determination apparatus (2000) determines the congestion degree of the target vehicle using the number of the persons (30) positioned in each of two or more of the areas (20).

Abstract: To provide a method for producing an aqueous polytetrafluoroethylene dispersion, whereby the formation of fluorinated oligomers as byproducts is minimized, CFT of the formed coating film is large, and a highly concentrated aqueous polytetrafluoroethylene dispersion is easily obtainable.

Abstract: The glove box includes a partition plate and a side wall. The partition plate is removable in a state in which the glove box is opened, and partitions the storage space of the glove box so as to divide the storage space into two parts in the vehicle front-rear direction. The side wall is provided on both sides in the vehicle width direction, and a locking portion for locking the partition plate is provided inside.

Abstract: Provided is a fluorine-containing copolymer composition capable of forming a uniform coating. The composition comprises a fluorine-containing copolymer having units derived from tetrafluoroethylene, units derived from ethylene, and 0.4 to 1.0 mol % of at least one functional group selected from the group consisting of a carbonyl group-containing group, an acid anhydride group, a carboxy group, a hydroxy group, an epoxy group, an amide group, an amino group, and an isocyanate group, and an aliphatic compound having 6 to 10 carbon atoms having one carbonyl group.

Abstract: A bacteria detection device moves a stage on which a detection chip is placed with a membrane filter fixed thereon by a first driving mechanism and a second driving mechanism in front-rear direction and in left-right direction so that an image of an upper surface of the membrane filter to which excitation light from a light emitter aligned with a imaging range by an imaging unit is taken. If bacteria to which a fluorescent label has been bound is captured on the upper surface of the membrane filter, the imaging unit can take an image of the bacteria as luminous points. A controller counts the luminous points in the image taken by the imaging unit so that the bacteria captured on the upper surface of the membrane filter can be detected.

Abstract: To provide a process by which from a mixture containing a fluorinated copolymer, an unreacted monomer and a polymerization medium, the unreacted monomer and the polymerization medium can efficiently be recovered, and a lower polymer contained in the obtainable fluorinated copolymer can readily be reduced.

Abstract: A process for producing a fluorinated copolymer includes polymerizing a fluorinated monomer having a carboxylic acid functional group or a sulfonic acid functional group and tetrafluoroethylene by a solution polymerization method in a polymerization medium in the presence of a polymerization initiator to obtain a mixture. The mixture contains a fluorinated copolymer, an unreacted fluorinated monomer having the carboxylic acid functional group or the sulfonic acid functional group, and the polymerization medium. The mixture is continuously or intermittently transferred to an evaporation container equipped with a stirring machine and heated in the evaporation container with stirring to evaporate and recover a mixed liquid. The mixed liquid contains the unreacted fluorinated monomer and the polymerization medium with which the polymerization initiator is mixed. The recovered mixed liquid is heated to decompose the polymerization initiator.
