  • Publication number: 20240348947
    Abstract: [Problem] An imaging device that can increase the dynamic range of pixel signals is provided. [Means of Solution] An imaging device according to an embodiment of the present disclosure includes: a plurality of pixels that are exposed during a same period; and an AD converter that digitizes an analog pixel signal output from each of the plurality of pixels. Further, each of the plurality of pixels includes a photoelectric conversion circuit that photoelectrically converts incident light, a first source follower circuit that amplifies an output signal of the photoelectric conversion circuit, a signal holding circuit that holds an output signal of the first source follower circuit, and a second source follower circuit that amplifies a signal read out from the signal holding circuit and outputs the signal as the pixel signal. Furthermore, a ramp signal including a slope portion in which a voltage level changes like a ramp is supplied to the signal holding circuit.

  • Patent number: 7368497
    Abstract: A resin composition which can be used to form a prepreg having sufficient flexibility to prevent cracking from occurring therein is provided. Further, a prepreg having sufficient flexibility to prevent cracking from occurring, a prepreg having excellent workability even in the case where the resin composition in the prepreg is in an uncured state, and a laminate provided with such a prepreg are also provided. The resin composition is used to form a sheet-shaped prepreg by impregnating a base material with the resin composition, and the composition comprises a first thermosetting resin, a second thermosetting resin having a lower weight average molecular weight than that of the first thermosetting resin, a curing agent, and a filler. The prepreg is formed by impregnating a base sheet material with the resin composition described above. The laminate is formed by laminating a metallic foil on the prepreg and then molding them by heating under pressure.
