A displacement sensor includes a first emission particles layer provided to be contactable with a measurement object, and in which first emission particles that emit light at a first wavelength by excitation energy are distributed over at least a one-dimensional extent, a second emission particles layer in which second emission particles that emit light at a second wavelength different from the first wavelength by the excitation energy are distributed over the above one-dimensional extent, and a spacer layer that separates the first emission particles layer and the second emission particles layer in a direction intersecting the above one-dimensional extent, and which includes an excitation energy absorbent that absorbs the excitation energy.

A foam molded article includes a main agent resin, a filler of greater than or equal to 15% by mass and less than or equal to 80% by mass, and a foaming agent of greater than or equal to 0.01% by mass and less than or equal to 10% by mass, and a foaming ratio caused by the foaming agent is greater than or equal to 1.1 times.

Foam molded article

Provided is a displacement measurement system including: a sensor that is contactable with a measurement target object and includes a first spacer that has at least a one-dimensional spread, and two or more types of light emitting particles that are distributed over the spread of the first spacer and emit light at different wavelengths by an excitation energy; an excitation energy source that causes the two or more types of light emitting particles included in the sensor to emit light; and a light receiver that receives light emitted from the sensor.

An ultrafine fiber production device has a first heating unit, a nozzle unit, a hot air heating unit, a hot air blowing unit, a second heating unit, and a fiber collecting unit. The first heating unit melts a thermoplastic resin. The nozzle unit discharges the thermoplastic resin melted by the first heating unit. The hot air blowing unit performs fiber forming by blowing high-temperature gas produced by the hot air heating unit to the melted thermoplastic resin discharged by the nozzle unit and by extending the thermoplastic resin. The second heating unit further heats, extends, and fines produced fibers. The fiber collecting unit collects the thermoplastic resin in a fibrous form which is fined by the second heating unit.

Ultrafine fiber production method and production device

An ink jet device includes a plurality of ink jet heads each including an ink housing unit that houses therein ink, a pressure application unit that ejects a droplet of the ink by applying pressure to the ink, and a nozzle through which the droplet of the ink is ejected, wherein with respect to at least one of the plurality of ink jet heads, a preliminary drive operation and a main drive operation are performed, the preliminary drive operation is an operation of pushing the ink toward an outer edge of the nozzle to the extent that the droplet of the ink is not ejected through the nozzle, and the main drive operation is an operation of ejecting the droplet of the ink through the nozzle after performance of the preliminary drive operation.
