The invention relates to a rolling device for rolling and unrolling a leash, especially for leading an animal. The rolling device includes a leash roller mounted rotatably on a carrier and reset, by aresetting device, into a rolled-up position in which the leash is wound around the leash roller; a blocking mechanism that blocks the unrolling of the leash from the leash roller; and a transmissiondevice coupled to the leash roller and causing the blocking of the blocking mechanism when a predetermined leash length is unrolled from the leash roller. A simple configuration with high operating reliability and low wear is provided with the transmission device having a first transmission element arranged rotatably on the carrier and a second transmission element arranged nonrotatably on the carrier. The first transmission element and the second transmission element have an outer circumference and an inner circumference associated with one another, which mesh with one another at least in anactive state.

The invention discloses an intermediate fixture and a method thereof for preparing semiconductor laser failure analysis samples. The intermediate fixture includes a first clamping part and a second clamping part; the first clamping part is used to clamp a TO laser, and holds a TO The first clamping part of the laser can obtain the cold mounting sample after injection molding, and the second clamping part is used to fix the cold mounting sample and control its grinding thickness; the first clamping part includes the first shell and the cylindrical block; the second The clamping part includes a second shell, an adjusting part and a pad; the pad can move up and down under the action of the adjusting part, and at the same time adjust the size of the part of the cold mounting sample exposed to the sample groove. The preparation process of the present invention has no high-temperature operation and effectively protects the chip; at the same time, no expensive micro-nano processing equipment is required, and the sample preparation process is simple and easy to operate; the prepared samples can be directly used for electroluminescence, photoluminescence and electron beam induced current failure analysis and defect detection.

The invention relates to a device for permanently joining at least two components, comprising at least one power source for providing energy to bring about the joint.

A method for producing an electronic assembly (5), in particular an electronic assembly (5) for a gearbox control module, is specified, the method comprising the steps of: providing a printed circuit board (10) having a first A side (12) and a second side (14) facing away from the first side (12) and having at least one first electronic component (70) arranged on the first side (12) of the printed circuit board (10) ; the printed circuit board ( 10 ) is at least partially arranged on the reference surface ( 40 ) with the second side ( 14 ); applying a sealing material ( 50 ) which is substantially non-flowable before age hardening to the first side ( 12), wherein the sealing material (50) is coated such that the sealing material (50) surrounds a partial area (20) of the first side (12) of the printed circuit board (10); the second device (80 ) is at least partially arranged on the reference surface (40), so that the second device (80) is partially pressed into the sealing material (50); the second device (80) is electrically connected to the printed circuit board (10); applying a covering material (60), in particular a covering material (60) that is flowable before age hardening, to the first side (12) of the printed circuit board (10) The partial area (20) surrounded by the sealing material (50) is applied to the first component (70); the sealing material (50) is age-hardened; and the covering material (60) is age-hardened.
