The metal plate has two rising members bended to the case side at both ends in the direction between the bearings. Two walls of the outer hull of an opening of the case at both ends in the direction between the bearings and the two rising members of the metal plate are alternately opposed, and the opposed walls of the case and the rising members of the metal plate are fixed using adhesives."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical pickup and disc drive using optical pickup","description":"An optical pickup having a case made of a resin material reinforced with glass fiber, inorganic filler or the like with polyphenylene sulfide as a base material, and a metal plate formed of a material","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8516511","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.
