A liquid layer, an air layer, and a solvent layer are formed in the nozzle in this order from the side of the supply passage, to prevent drying of the liquid in the nozzle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cleaning and drying-preventing method, and cleaning and drying-preventing apparatus","description":"A cleaning and drying-preventing method including: positioning a nozzle in a container such that a funnel-like inner circumferential surface of the container is located around a periphery of a distal ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8512478","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.
