The present invention reduces the burden of installing a detection sensor for monitoring a liquid such as a liquid resin. A detection sensor according to the present invention comprises: an optical transmission body group that includes a plurality of optical transmission bodies which each transmit light supplied from a light source; and a thin band-shaped holder that supports the optical transmission body group. The holder is provided with a first holder element that supports one or more optical transmission body groups, on a support surface that expands in a first direction and in a second direction orthogonal to the first direction. The plurality of optical transmission bodies are arranged in the second direction.

It is intended to improve NOx removal efficiency. A NOx removal device (10) includes: an ammonia injection unit (11) provided inside a duct (3) inside which an exhaust gas flows through and configured to inject ammonia to the exhaust gas flowing through inside the duct (3); a NOx removal catalyst (13) provided inside the duct (3) and downstream of the ammonia injection unit (11); and a rectifying unit (20) provided inside the duct (3) and upstream of the ammonia injection unit (11) so as to be spaced apart from the ammonia injection unit (11) by a predetermined distance and configured to rectify an exhaust gas flowing through inside the duct (3).

To provide a molded product manufacturing method which makes it possible to suppress variations in the forming quality of members being processed. This manufacturing method comprises a disposition step for disposing a member being processed (20) on a forming die (10), a supply step for supplying a bladder with a fluid above the member being processed, and a lowering step for lowering a bladder (30). The member being processed is sheet-shaped and has a greater area than an upper face of the forming die. The bladder is such that an opening of a rigid box is covered by a stretchable sheet-like member. In the supply step and the lowering step, a regulating member is used which, as the bladder lowers, prevents a region in which the bladder expands from protruding from a region in which the bladder makes contact with the member being processed.

The present invention improves the efficiency of liquefying a material gas. This liquefaction device comprises: a material pipe through which a material gas flows; a magnetic body which is connected to the material pipe and is capable of adsorbing the material gas supplied from the material pipe, the temperature of the magnetic body decreasing when application of a magnetic field is stopped; and a magnet which applies the magnetic field to the magnetic body. The magnet stops applying the magnetic field to the magnetic body in a state in which the magnetic body has adsorbed the material gas, whereby the magnetic body cools the adsorbed material gas.

The present invention improves the efficiency of liquefaction of a feed gas. This liquefaction device includes: a feed pipeline through which a feed gas flows; a feed-cooling part by which the feed gas being flowing in the feed pipeline is cooled with a refrigerant; a magnetic refrigeration part which is disposed downstream from the feed-cooling part along the feed-gas flow inside the feed pipeline and by which the cooled feed gas is cooled with a magnetic body to liquefy the feed gas; and a magnetic-body-cooling part in which the magnetic body that has cooled the feed gas is cooled with a refrigerant.
