  • Patent number: 11917312
    Abstract: Solid-state imaging apparatuses are disclosed. In one example, an apparatus includes a first substrate and a second substrate. The first substrate includes a pixel array that is arrayed in columns and rows. The second substrate is stacked on the first substrate, and includes first and second analog circuits that overlap with the pixel array in a third direction intersecting the column and row directions. A pixel divider section divides pixels in the array into a first area and a second area. The first and second analog circuits respectively connect to pixels in the first and second areas, and are adjacent to each other with a circuit divider section interposed therebetween, the circuit divider section being located with an overlap with the pixel divider section in the third direction.

  • Patent number: 11905404
    Abstract: Provided is a resin composition that is capable of producing a cured product having excellent environmental suitability, high strength, and excellent flame retardancy, and that is suitably usable as a matrix resin for fiber-reinforced plastics. A resin composition contains (A) an epoxy resin, (B) a cyanate resin, (C) an aromatic amine curing agent that is liquid at 25° C., and (D) a phosphorus-containing compound represented by formula (1). Preferably, in formula (1), R1 and R2 each independently represent an alkyl group or an aryl group, and X and Y are an oxygen atom.
