Title: Manufacture of sealed container
Inventor: AKAZAWA KIYOHIDE
IPC: B65D77/20
Filed: 1989-03-03
Abstract: PURPOSE:To provide the combined features of sealing integrity and opening easiness by applying heat sealing to a lid from above using a sealing plate having a sloping surface set at a specific angle to the surface of the flange under a specific condition. CONSTITUTION:A lid 2 is sealed to the flange 3 of a container 1 having a laminating strength of 300-2000g/mm between the sealed layer 6 and its adjoining layer 8 and a thickness of the sealed layer 6 of 10-70mum. At this time, the lid 2 is placed on the flange 3 with an angle theta set at 3-15 deg. between the sloping surface 4 of a sealing plate 5 and the flange surface from the inner to outer peripheral edge of the container. With respect to the sealing operation, the sealing plate 5 is set on the flange 3 with its inner peripheral edge E positioned thereon and the heat sealing is applied to the lid 2 from above under such heat pressing conditions as to make the resulting sealing strength larger than the laminating strength and cause the resinous swellings 9, 10 and 11 to be extended from the resins formed by the sealing layer 6 and the adjoining layer 8 on a boundary between the sealed part and the unsealed part on the container side. This ensures the combined features of sealing integrity and opening easiness.

Title: Method and apparatus for measuring gas concentration
IPC: G01N21/39
Filed: 1992-03-11
Abstract: PURPOSE:To obtain the method and apparatus for measuring the concentration of gas, which correct pressure without using a highly stable amplifier having high gain. CONSTITUTION:The modulated laser light is split with a splitter 6. One split light is transmitted through methane gas in a cell 7 for gas to be measured (a) whose concentration is unknown. The cell 7 is kept at a constant temperature. The secondary differentiation signal T02 is obtained by performing phase- sensitive detection of the split light with lock-in amplifiers 15 and 16 through a photodetector 9. The value of the signal T02 is divided by the value of the primary differentiation signal T01 with a divider 17. Thus, the concentration of the gas is computed. The light is transmitted through a reference gas cell 8 containing methane gas having a constant temperature, a constant pressure and a known concentration. The light undergoes phase-sensitive detection with a lock-in amplifier 19. The gas concentration is corrected based on the obtained secondary differentiation signal.
