Production of glass tube for encapsulating electronic components comprises coaxially inserting starting glass tubes into each other, heating tubes together in heating zone to deform them and joining tubes together

摘要

Production of a glass tube (12) comprises coaxially inserting starting glass tubes into each other, heating the tubes together in a heating zone (8) to deform them and joining the tubes together to form the glass tube. Independent claims are also included for the following: (1) a device for the production of the glass tube; and (2) a glass tube produced in the above process.
