Abstract: A composite resin molded product of the invention is a composite resin molded product, including: a main agent resin; and a plurality of natural fibers dispersed in the main agent resin. The plurality of natural fibers each contain a microorganism or an enzyme. When the composite resin molded product is 100% by mass, a content rate of the plurality of natural fibers each containing the microorganism or the enzyme in the composite resin molded product is 10% by mass or more and 99% by mass or less. At least one of the plurality of natural fibers is exposed on a surface of the composite resin molded product. At least a part of a surface of the at least one of the plurality of natural fibers is coated with a hydrolyzable coating resin.

Abstract: 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.

Abstract: A pH sensor includes a glass electrode unit to respond to pH; a comparative electrode unit to be measured for its potential relative to the glass electrode unit; a main pipe to convey test liquid; and a fluid inlet connected to the glass electrode unit and the main pipe. The glass electrode unit includes: a first storage unit filled with electrolyte solution; a first electrode to electrically connect the inside and outside of the first storage unit; a glass film disposed between the first storage unit and the main pipe; and a first pressure transmission unit connected to the fluid inlet. The first pressure transmission unit regulates the internal pressure of the first storage unit to control the pressure difference between the first storage unit and the main pipe separated by the glass film. The comparative electrode unit includes: a second storage unit filled with buffer solution; a second electrode to electrically connect the inside and outside of the second storage unit; a liquid junction unit disposed between the second storage unit and the main pipe; and a second pressure transmission unit connected to the fluid inlet. The second pressure transmission unit regulates the internal pressure of the second storage unit to control the pressure difference between the second storage unit and the main pipe separated by the liquid junction unit.
