  • Publication number: 20190185656
    Abstract: A curable composition contains a resin containing a curable group, a colorant, a polymerization inhibitor, and a polymerization initiator. A manufacturing method of the curable composition includes a colorant dispersing step of mixing together the resin containing a curable group, the colorant, and the polymerization inhibitor and a mixing step of mixing together the colorant dispersion and the polymerization initiator so as to obtain the curable composition. A cured film is obtained by curing the curable composition. A color filter, a solid-state imaging element, and an infrared sensor have the cured film. A manufacturing method of the cured film includes a curable composition layer-forming step, an exposure step, and a development step.

  • Publication number: 20190187601
    Abstract: An abnormality determination apparatus includes: an audio data acquisitor that acquires audio data of an apparatus to be judged for determining presence or absence of abnormality; an abnormal sound detector that detects an abnormal sound based on the audio data acquired by the audio data acquisitor; and a hardware processor that determines whether the abnormal sound is such a sound that an operation of the apparatus to be judged should be restricted based on a subsequent secular change of the abnormal sound when the abnormal sound is detected by the abnormal sound detector, and restricts the operation of the apparatus to be judged when the hardware processor determines that the abnormal sound is such a sound that the operation of the apparatus to be judged should be restricted.
