The current-collecting lead for being welded to a collector welded to an upper portion of an electrode group and also to a sealing assembly of an cylindrical secondary battery includes: a flat surface part welded to the collector, and a top part formed to be curved and protrude approximately in the shape of a dome from the flat surface part and welded to the sealing assembly. A central opening is formed at a central portion of the top part. Around the central opening, a plurality of welding projections are formed to protrude toward the sealing assembly. The welding projections serve as welding spots to the sealing assembly. The top part is deformed by a pressing force from the sealing assembly to be brought into surface contact with a corner portion of a convex portion formed on a lower surface of the sealing assembly.

The invention is directed to provide a cylindrical nickel-hydrogen storage battery having high discharge power densities both at SOC 50% and at SOC 20%. In an alkaline storage battery according to an embodiment of the invention, a nickel positive electrode formed into a rectangular shape has a short side length of X and a long side length of Y, the ratio (Y/X) of the long side length to the short side length is 25 or more and 40 or less (25≦Y/X≦40), the short side length is 25 mm or more and 45 mm or less (25 mm≦X≦45 mm), and the battery capacity is 3 Ah or more and 7 Ah or less.
摘要:
Compounds having a 16-membered macrolide ring, and related to the milbemycins and avermectins, with substituents at positions 5, 13, 25 and optionally also 23, have acaricidal, insecticidal and anthelmintic properties. They are useful for treating various pests in plants and animals.

Derivatives of milbemycins D, A.sub.3 and A.sub.4 and of the corresponding sec-butyl compound have a halogen atom at the 13-position; at the 5-position, they have an oxygen (keto) atom, an oxime group or a substituted oxime group. They may be prepared from known compounds by any appropriate combination of halogenation, ketonization and oximation.
摘要:
The invention works in an environment where an optical disc, such as a CD, is inserted into an optical disc player. The disc typically has a label that is affixed to an upper surface of the disc. If the label is loose, for instance if a portion of the disc becomes raised toward the grill, the CD will become stuck since the raised label will not exit the opening in the grill. This obstructs the disc rollers and causes the motor to not be able to push the disc out of the player. The present invention senses this event and invokes an ejection routine to allow the raised label portion to be rotated to a position where it will not obstruct the slit in the grill or the roller.

8,9 and/or 14,15 epoxidized and 5-acylated milbemycins and avermectins are prepared from the parent milbemycins and avermectins by epoxidation and acylation (in either order). They have enhanced anthelmintic, acaricidal and insecticidal activities.
