摘要

In a method for manufacturing a glass plate that includes chamfering processing for chamfering an edge surface of a glass plate, the chamfering 5 processing includes a step of forming a chamfered surface by irradiating the edge surface of the glass plate with a laser beam, and a step of heating the glass plate before the chamfered surface is formed. When a temperature of the glass blank at which the glass blank is heated is Tp ['C], a glass transition point of the glass blank is Tg ['C], and an average coefficient of linear thermal expansion 10 of the glassblankiso [U"C], (Tg-Tp)S -5.67 x 107. o+840issatisfied.

About LaoBiz | Data Sources, Services & Compliance

数据来源 Data Sources

LaoBiz.com 是面向全球企业的老挝商业信息与市场研究平台，帮助企业更高效地了解老挝市场、发现商业机会并寻找潜在合作伙伴。平台商业信息主要来源于老挝政府主管机关维护的官方公开登记系统，包括工贸部 NED（企业注册）、BNED（经营许可）、eBRS（工商登记）与财政部 TaxRIS（税务登记），以及知识产权等相关官方公开渠道。LaoBiz 不创造或修改企业登记事实，而是在上述官方公开信息基础上，通过数据整理、标准化处理、多语言转换、行业分类和智能检索技术，让分散的信息更加易于查询、理解和应用。平台持续关注官方公开数据变化，并通过数据同步机制帮助用户获取企业最新公开状态。

LaoBiz.com is a Laos business-information and market-research platform for global companies—helping users understand the Lao market, discover opportunities and find potential partners more efficiently. Commercial records are drawn mainly from official public registry systems maintained by Lao competent authorities—including MoIC’s NED (enterprise registration), BNED (business licences) and eBRS (business registration), MoF’s TaxRIS (tax registration), and related official public channels such as intellectual-property filings. LaoBiz does not create or alter registry facts; on top of those official public records we organise, standardise, translate, classify by industry and index for search so fragmented filings are easier to find, understand and use. We continuously watch official public-data changes and offer sync tools so users can check an enterprise’s latest public status.

数据核验与更新 Verification & Updates

LaoBiz.com 企业详情页提供「同步最新数据」功能。用户可针对指定企业记录主动发起数据核验，平台将根据公开系统返回的信息更新页面展示内容。由于企业登记、税务状态及相关公开信息由不同主管机构维护，数据更新时间可能存在差异。对于商业决策、法律文件、政府审批等正式用途，请以主管机关最新发布的信息及正式文件为准。

Each LaoBiz.com company profile offers “Sync latest data”. Users can actively request verification for a specific enterprise; the page is then refreshed from what the public systems return. Because company registration, tax status and related public filings are maintained by different authorities, update timing may vary. For business decisions, legal documents, government approvals and other formal uses, please rely on the latest information and official documents issued by the competent authority.
