A pressure-resistant glass sphere of the present invention is composed of a pair of glass-made hollow hemispherical bodies, wherein the glass-made hollow hemispherical bodies are joined with each other at ground joint surfaces located on an equatorial plane of the pressure-resistant glass sphere so that the ground joint surfaces serve as a joining surface, and characterized in that a thickness of a spherical shell of the glass-made hollow hemispherical bodies is thicker at an equatorial plane portion than the portion other than the equatorial plane portion having a predetermined width from the ground joint surfaces."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressure-resistant glass sphere","description":"In a pressure-resistant glass sphere used for exploration of deep sea, ocean floor or the like, it is an important issue to reduce weight and increase a floating force while keeping pressure resistanc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10486851","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.
