  • Patent number: 11109492
    Abstract: Provided is a structure that has highly reliable electroconductive pattern regions, that offers an extremely simple manufacturing process, and that has excellent electrical insulation between the electroconductive pattern regions. This structure (10) having electroconductive pattern regions is provided with a support (11), and, on a surface configured by the support, a layer (14) in which insulation regions (12) containing a copper oxide- and phosphorus-containing organic substance and electroconductive pattern regions (13) containing copper are disposed next to one another. This stack is provided with: a support, a coating layer containing copper oxide and phosphorus and disposed on a surface configured by the support; and a resin layer disposed so as to cover the coating layer.

  • Patent number: 9372155
    Abstract: Roe W is loaded on a loading tray 6, the roe W is irradiated with light from light irradiation means 11, and an image of at least a part of the roe W irradiated with light from the light irradiation means 11 is taken by image pickup means 12. Image processing of the image Pa taken by the image pickup means 12 is performed to measure a light transmissive value of the light passing through the roe W; and maturity of the roe W is determined based on the measured light transmissive value. This enables a roe maturity determination device and a roe maturity determination method capable of determining precisely roe maturity.
