Grooving is performed on a lower surface and an upper surface of the peripheral portion of the upper chamber window, to thereby form a plurality of grooves thereon. Flash light traveling into the peripheral portion of the upper chamber window during irradiation with flash light is reflected by the plurality of grooves and is prevented from traveling toward the O ring. This significantly reduces an amount of flash light reaching the O ring, and thus degradation of the O ring due to the irradiation with the flash light can be prevented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light irradiation type heat treatment apparatus and method for manufacturing heat treatment apparatus","description":"A sealing structure is achieved by sandwiching an O ring between an upper chamber window and a chamber side portion and pressing a clamping ring against a top of a peripheral portion of the upper cham","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10475674","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.
