A nanocrystal production method includes a light irradiation step of applying light to a surface of a metal material immersed in water to form nanocrystals on the surface. In this nanocrystal production method, the metal material contains iron, the nanocrystal contains at least one of iron oxide and iron hydroxide, and in the spectrum of the light, a wavelength at which the intensity is maximum is not less than 360 nm and less than 620 nm.

Nanocrystal production method, and steel production method

The present invention aims to provide a network projector which has a simple security function via a network. The network projector comprises a power source unit which supplies power to the network projector and a display signal control unit which, when confirming that a connection confirmation signal which is transmitted at a fixed period from a host computer via a network is not inputted for more than a predetermined time, outputs a supply stop signal to the power source unit indicating that the supply of power should be stopped.
