Title: Spiral nonaqueous battery
Inventor: KURIBAYASHI ISAO
IPC: H01M10/0587
Filed: 1991-09-09
Abstract: PURPOSE:To enhance the adhesion between active material particles and metallic foil and their production efficiency so as to enable a spiral nonaqueous battery to withstand heavy loads by setting the surface roughness of the metallic foil serving as a current collector within the range of 0.1 to 0.9mum. CONSTITUTION:Metallic foil serving as a current collector is subjected to etching, laser treatment, electroless plating, electrolytic plating or sandblasting, etc., so that the surface roughness of the foil is controlled to 0.1 to 0.9mum, desirably 0.2 to 0.8mum, or more desirably 0.6 to 0.8mum. When the surface roughness is less than 0.1mum the adhesive property of the metallic foil is scarcely enhanced, while when the roughness is more than 1mum cutting of the metallic foil may occur during application.

Title: Package structure for mounting quartz waveguide
Inventor: MOROSAWA KENICHI
IPC: G02B6/122
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To suppress deviation of the center wavelength characteristics in an array waveguide diffraction grating formed by a quartz waveguide, by connecting a first package with an attaching part through a stress absorbing means and thereby preventing the stress from being propagated to the fixed quartz waveguide. SOLUTION: The attaching part 8 is connected to the first package 4 through the stress absorbing means 10 constituted of a corrugated plate material. Because of this connection, when a mechanical stress is generated in the attaching part 8 due to a minute dimensional errors, warpage or the like of each package, the stress is relaxed and absorbed by the deformation of the corrugated stress absorbing means 10, in screw-fixing the first package 4 to a second package 6. As a result, the stress can be reduced which is propagated to the first package 4 and the array waveguide diffraction grating 2 of the quartz waveguide 3 fixed on the first package 4.
