The angle sensor includes a detected unit provided inside of a top end section of the motor output shaft and a detecting unit provided on the cover member so as to be opposed to the detected unit through a minute clearance. A metal disk-shaped reinforcing plate is molded and fixed inside of a cover main body of the cover member mainly formed of a synthetic resin material, thus enhancing the entire rigidity of the cover main body."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable valve device for internal combustion engines and valve timing control device","description":"A variable valve device for an internal combustion engine for varying operating characteristics of engine valves by changing a relative rotational phase of a camshaft to a timing sprocket has an elect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9752467","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.
