The chuck includes a base body, a drive ring, and gripping members for contacting the article at its edge. The gripping members are eccentrically movable with respect to the center of the article and driven by a drive ring rotatably mounted to the base body, so that the drive ring is rotatable against the base body around the axis. The relative rotational movement of the drive ring against the base body is carried out by either holding the base body and rotating the drive ring or by holding the drive ring and rotating the base body, whereby the to-be-held-part (drive ring or base body) is held without touching the respective to-be-held-part by magnetic force."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for treating disc-like articles","description":"A device for treating a disc-like article with a fluid, includes elements for dispensing a fluid onto the article and a chuck for holding and rotating the article around an axis perpendicular thereto.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8490634","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.
