Title: Device for wave soldering of printed circuit board assemblies
Inventor: THIELE JUERGEN DIPL ING
IPC: B23K3/06
Filed: 1988-03-23
Abstract: In the case of a device for wave soldering of printed circuit board assemblies, a soldering frame with central supports is normally used to avoid the printed circuit board assemblies bending, which soldering frame suspends said printed circuit board assemblies. In order to be able to carry out wave soldering of printed circuit board assemblies in a manner which is as simple as possible and without using soldering frames, at least one supporting element (7, 8, 9) is arranged in front of and behind the soldering bath (LB), in the course of a transportation device (TE), such that the printed circuit board assemblies (4) are supported. The supporting elements (7, 8, 9) are arranged such that they can be displaced transversely with respect to the movement direction of the printed circuit board assemblies (4). The device is also suitable for wave soldering of very broad printed circuit board assemblies. <IMAGE>
Patent DE-3810319-A1 (DE)
Title: Blister pack
Inventor: STREULI HEINRICH
IPC: B65D75/36
Filed: 1988-03-26
Abstract: The covering panel (1) consisting, for example, of cardboard is provided with notch lines (8-11) on the two surfaces (4, 7) facing away from one another, adjacent notch lines (8, 10 or 9, 11) of the two surfaces (4, 7) form an intended tearing point for manually pressing the covering panel (1) through. These adjacent notch lines (8, 10 or 9, 11) are offset relative to one another, transversely to their extent. The covering panel material serves as the intended tearing point between the mutually offset notch lines (8, 10 or 9, 11), that is to say specified by the size of the offset. This can be changed empirically depending on the covering panel material in order to achieve the pressing-through by hand. As a result, the difficult production of the depth of the notch lines (8-11) is avoided. Additionally, the size of the offset can be greater than the thickness of the covering panel. An effective barrier is achieved, for example when packaging products which are sensitive to moisture or have an intense odour. <IMAGE>

Title: High-performance semiconductor component
Inventor: MALIESKE GUENTER DIPL PHYS
IPC: H01L21/60
Filed: 1988-07-09
Abstract: In high-performance semiconductor components for blocking (cutoff) voltages of up to 100 volts, the semiconductor body is of very thin dimensions and particularly prone to breakage from the start of production. An arrangement according to the invention substantially improves the mechanical stability of such a semiconductor body and simultaneously also ensures optimum dissipation of heat loss. The semiconductor body, which has a sequence of layer-type zones and an intermediate pn junction, is permanently joined over the entire surface of one of its main faces to a carrier body made from semiconductor material which in the entire volume has a doping of at least the surface concentration at the main face of the semiconductor body which is to be joined. The arrangement is produced by arranging a starting wafer with zone sequence and a uniformly doped further starting wafer in a prescribed spatial and electrical assignment in the stack, and joining them permanently by bonding to form a component. The joint can be produced by alloying or soldering. The thickness of the carrier body is at least half that of the semiconductor body. Use in welding operation and battery charging.

Title: Method of controlling at least one leakage space of a valve device and device for carrying it out
Inventor: MIETH HANS OTTO DIPL ING
IPC: F16K37/00
Filed: 1988-01-20
Abstract: The invention relates to a method of controlling at least one leakage space of a valve device according to the pre-characterising clause of Claim 1. The proposed method, when applied to a multi-way change-over valve which is already novel per se in its design, provides a valve device which is novel in terms of the given switching functions and of its properties, especially the leakproofing of each individual seat region. Where the method is concerned, this is achieved, inter alia, in that, in the position of the valve device deviating from the basic position, there is provided for the particular changed-over valve seat a substitution of the closing member or closing part respectively shutting off the leakage space from the interior by the other respective closing member or closing part (Figure 7). <IMAGE>

Patent DE-3841911-A1 (DE)
Title: Sanitary fitting
Inventor: SCHMIEG GEORG
IPC: F24D17/00
Filed: 1988-12-13
Abstract: A tub-shower fitting known per se is converted, by a slight modification, to a sanitary fitting with automatic discharge valve. The outflow connection stub, which usually leads to the tub, is used, in this arrangement, as a drainage connection stub. The modification consists in that the double valve cone of the tub-shower changeover device is restricted in its movability such that it can no longer reach the valve seat which releases the path to the shower outflow connection stub. Rather, without flowing water, the double valve cone remains, with a comparatively small gap, in front of that valve seat which controls the path to the drainage outflow connection stub. With this modification, the otherwise known shower-tub changeover device functions as an automatic discharge valve.
