  • Manufacturing method for gas cell, manufacturing method for magnetic field measurement apparatus, and gas cell
    Patent number: 10393825
    Abstract: A manufacturing method for a gas cell includes disposing a holding member including a coating material in a reservoir of a cell having a main chamber, the reservoir communicating with the main chamber, and an opening provided in the reservoir, sealing the cell, heating the holding member so as to generate a vapor of the coating material in the cell, and cooling the cell so as to form a film of the coating material on an inner wall of the cell.
    Type: Grant
    Filed: June 7, 2017
    Date of Patent: August 27, 2019
    Assignee: SEIKO EPSON CORPORATION
    Inventor: Tatsunori Miyazawa
