Abstract: An exemplary embodiment of the present disclosure provides an avalanche photodiode (APD), comprising: a p-doped substrate; a first n-doped region; an n-doped epitaxial region; a plurality of n-doped wells; and a first p-doped region. The first n-doped region can be positioned above at least a portion of the p-doped substrate. The n-doped epitaxial region can be positioned above at least a portion of the first n-doped region. The plurality of n-doped wells can be positioned within the first n-doped epitaxial region. The first p-doped region can be positioned above the n-doped epitaxial region and the plurality of n-doped wells.

Abstract: Connecting ends on a hose piece comprising several metal layers, in particular a strip wound metal hose piece, are produced by fixing the overlapping metal layers of a hose of larger length or of an endless hose in the region of the point of separation through welding and subsequently cutting off the hose piece from the longer hose or the endless hose. For simple and inexpensive fixing of the metal layers in the region of the point of separation, a welding seam is generated which extends through at least part of the periphery of the hose or about its entire periphery, using roller seam welding. The hose piece can subsequently be separated along the welding seam obtained in this manner, e.g. along its central line, thereby ensuring permanent and reliable fixing of the metal layers in the region of the connecting end.

Abstract: Connecting ends on a tube piece comprising several metal layers, in particular a wound metal tube piece, are produced by fixing the overlapping metal layers of a tube of larger length or of an endless tube in the region of the point of separation through welding and subsequently cutting off the tube piece from the longer tube or the endless tube. For simple and inexpensive fixing of the metal layers in the region of the point of separation, the invention proposes effecting a welding seam which extends through at least part of the periphery of the tube or about its entire periphery, using seam welding. The tube piece can subsequently be separated along the welding seam obtained in this manner, e.g. along its central line, thereby ensuring permanent and reliable fixing of the metal layers in the region of the connecting end. The invention also concerns a tube piece having a connecting end produced in this manner.
