A first polarizing plate having a polarizing axis in a first direction is attached to an open window of the cover part, and a second polarizing plate having a polarizing axis in a second direction orthogonal to the first direction is attached to the open window so as to open and close. In a state where the second polarizing plate is closed, the second polarizing plate overlaps the first polarizing plate. In a state where the second polarizing plate is open, the first polarizing plate and the second polarizing plate are present on a straight line connecting the outside light source and the fuel cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inspection device, inspection facility and inspection device failure confirmation method","description":"An inspection device is adapted for inspecting whether or not there is a foreign matter or dirt adhered to a surface of a workpiece or whether or not there is a scratch on the surface of the workpiece","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10481103","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
