摘要:
A manufacturing apparatus prevents small defects from being formed in a surface of a glass film ribbon to the extent possible when the glass film ribbon is transported toward a downstream side while curved. The apparatus includes a direction converting device for converting a traveling direction of the glass film ribbon, which is drawn downward vertically from a forming device, from a vertical direction to a horizontal direction by transporting the glass film ribbon toward a downstream side while curved in a longitudinal direction of the glass film ribbon. The direction converting device includes a curve-supporting unit for supporting the glass film ribbon curved in the longitudinal direction. The curve-supporting unit includes two lines of end portion supporting parts for supporting widthwise end regions of the glass film ribbon without supporting a widthwise central region of the glass film ribbon.

Novel penicillins of the formula ##STR1## wherein R is a branched chain alkyl group of from 3 to 14 carbon atoms, and their pharmaceutically acceptable salts, are easily absorbed in the blood and tissues through oral administration and show excellent antimicrobial activity against Gram-positive and Gram-negative bacteria, particularly against microorganisms of the genus Pseudomonas, such as Pseudomonas aeruginosa.
摘要:
The manufacturing method for a glass film includes, in this order: a cleaving step of dividing a glass film (G) having a band shape into a product glass portion (Ga) and an unnecessary glass portion (Gb); and a collecting step of sequentially shattering the unnecessary glass portion (Gb), and collecting the shattered unnecessary glass portion. The cleaving step is followed by vibration regulating processing of regulating vibrations of the unnecessary glass portion (Gb) in a thickness direction thereof, the vibration regulating processing being executed in at least one location in the longitudinal direction of the unnecessary glass portion (Gb) together with the collecting step executed on a downstream side of the at least one location of the vibration regulating processing.
