Patent number: 10322635Abstract: A charging apparatus (1) for a vehicle that can be driven electrically has a charging cradle (4) with an access opening (8) and an electrical charging socket (5) is arranged in the charging cradle (4). A closure cover (7) is mounted pivotably in the charging cradle (4) and, in a closed position, covers the access opening (8) in the charging cradle (4) and, in an open position, opens said access opening. A sealing ring (12) which extends around the charging socket (5), and the closure cover (7) has a ring attachment (13) that makes contact with the sealing ring (12) along a ring contour of the sealing ring when the closure cover (7) is closed. Thus, the charging socket is sealed off reliably to the outside.Type: GrantFiled: October 14, 2015Date of Patent: June 18, 2019Assignee: Dr. Ing. h.c. F.

Patent number: 9941197Abstract: A strip-shaped substrate made from a film includes a plurality of units for producing chip carriers. Each unit has a chip island for fixing a semiconductor chip, electrodes for electrical connection of the semiconductor chip, and through-openings for structuring the unit. At least one through-opening forms an anchoring edge for a casting compound for encapsulating the semiconductor chip. A surface section of the film abutting the through-opening is chamfered to form the anchoring edge. The anchoring edge protrudes past the side of the film on which the chip island is arranged.Type: GrantFiled: June 15, 2015Date of Patent: April 10, 2018Assignee: HERAEUS DEUTSCHLAND GMBH & CO.

Patent number: 4489580Abstract: A flat workpiece such as a sheet metal workpiece is deformed by impacting e surface of the workpiece with one or several impacting tools while supporting at least a portion of the workpiece surface opposite the impacted surface. In order to control the deforming impact effect for achieving the intended shape of the workpiece, the impact strength of uniform drive impulses is modified in accordance with the desired shape. For this purpose the impacts are damped in accordance with a predetermined surface pattern of impact strengths corresponding to the desired shape. Such damping is accomplished by coating the workpiece surface prior to the impacting with a damping layer or layers having a different damping effect in different places on the surface of the workpiece in accordance with the mentioned pattern, whereby the uniform impact strength is modified in its effect in accordance with the pattern over the surface of the workpiece.Type: GrantFiled: August 15, 1983Date of Patent: December 25, 1984Assignee: Messerschmitt-Boelkow-Blohm Gesellschaft mit beschraenkter HaftungInventor: Siegfried Walter
