Title: Semiconductor component surface contacting system - uses thin aluminium wire and spark discharge cover precisely adjustable spark gap and stable protection gas flow during melting
Inventor: WEISS STEFAN
IPC: H01L21/607
Filed: 1980-10-06
Abstract: The contacting system is for prodn. of microswitching circuits, or integrated circuits, using gold or aluminium wires. For the first contact a ball is formed by melting of the wire by a spark discharge in a productive atmosphere. A protective gas nozzle with an electrode is approached towards the wire end. The formed ball is then welded under pressure to the contact surface. The wire is then brought to a second contact surface, where it is welded also under pressure. The electric spark discharge takes place over a constant, precisely adjustable spark gap. During the formation of the ball a stable, vibration-free, protective flow of the gas is guided round the ball. The approach of the protective gas nozzle with the electrode to the wire end has a sine-shaped path-time relation. During the approach the feed velocity is reduced proportionally to the reducing distance, the spark taking place at the smallest distance.

Title: Hydraulic shock absorber for a motor vehicle
Inventor: DIETRICH CHRISTIAN ING GRAD
IPC: F16F9/52
Filed: 1981-02-24
Abstract: Hydraulic telescopic shock absorber for a passenger vehicle, the piston rod and/or the area of the bottom valve of which contains a liquid (for example acetone), variable in its volume as a function of the temperature, either directly or in a sylphon bellows. At the same time a pin, the free, conically formed end section of which acts against a flow aperture passing axially through the piston or the bottom valve of the telescopic shock absorber, projects axially from the sylphon bellows or from a separating piston. When the hydraulic oil is relatively cold and hence viscous the liquid contracts, producing an annular gap between the free end of the pin and the flow aperture. Through this some of the hydraulic oil can escape by way of the flow aperture so that the damping force is reduced. As the hydraulic oil heats up, the liquid, in contrast, expands so that the flow aperture is fully or partially closed. Since the hydraulic oil, made less viscous due to heating, now flows only through the restricted apertures provided in the piston or the bottom valve, the damping force remains largely the same as when the hydraulic oil is colder.

Title: Device for dyeing sections or strands of hair
Inventor: MERGES HEINZ
IPC: A45D19/00
Filed: 1981-09-26
Abstract: A device for dyeing sections or strands of hair with the aid of a film which is impermeable to liquid is distinguished by the fact that the film (60) has on one side an adhesive coating (61, 64, 65) in the form of at least one uninterrupted strip which runs on at least one inner edge (62, 63) and/or outer edge (67) of the film (60) parallel to said edge. It is achieved in this manner that the film (60) rests firmly against the scalp and the divided hair on the film (60) is separated from the other hair so that dyeing of the entire length of the hair up to the scalp is possible without loss and without the dye running onto the surrounding area of the divided hair. Dyeing mistakes are avoided. For dyeing sections of hair, the edge (67) is used while the dyeing of strands of hair takes place by placing each strand of hair in a slit (62, 63) and by overlapping closure of the slit (62, 63). In both cases, the hair soaked in dye is packed into the remainder of the film (60) adhering to the scalp in order to accelerate the chemical reaction. <IMAGE>
