Title: Machine having a welding bar serving to form welded seams in a thermoplastic film
Inventor: BOCHTLER FRANZ
IPC: B29C65/00
Filed: 1984-12-01
Abstract: In order to ensure that in a device of this type the welding bar (4) is in contact over its entire length with the film web (1) to be welded, via its welding edge under uniform contact pressure, the welding bar (4) is designed so that it can be deflected in the plane of action of this contact pressure force and is arranged such that during the welding operation it is pressed onto the film web (1) by the force of a pre-tensioning device (45). The result is that the welding bar (4) can, under varying operating conditions, for example at varying welding temperatures, automatically adapt to the profile, which may be distorted, of a counter-edge which supports the film web (1), so that even under varying operating conditions a contact pressure force results, between the welding bar (4) and film web (1), which is uniform over the entire length. <IMAGE>

Title: Nozzle arrangement for the casting of thin strips
Inventor: HOCK STEFAN DIPL ING
IPC: B22D11/06
Filed: 1985-11-26
Abstract: To avoid non-uniform strip geometry during prolonged casting of thin strips by the deposition of a molten alloy on a moving cooling surface (3) using a nozzle (1) with a slot-shaped opening (2), the slot-shaped opening is chosen so that the direction of its edges from the central area towards the ends (8, 9) changes in such a way that there is both a directional component perpendicular to the movement of the cooling surface (3) and a component in the direction of the movement of the latter. It is thus possible, by pivoting the nozzle (1), to vary the distance between the slot-shaped opening (2) and the cooling surface (3) across the width of the strip. <IMAGE>

Patent DE-3543448-A1 (DE)
Title: Photodetector
Inventor: THOMPSON GEORGE HORACE BROOKE
IPC: H01L31/112
Filed: 1985-12-09
Abstract: A photodetector in the form of an optical field effect transistor consists of a semi-insulating InP substrate (1), a p<+> InP gate region (2), an n<-> InGaAs channel layer (3) and of source and drain contacts (5, 6). The light to be detected comes in through the underside of the semi-insulating InP substrate (1). The n<-> InGaAs channel layer (3) is thicker than the channel layer of a normal junction field effect transistor, but is not doped as highly, in order to achieve efficient light absorption and a low capacity between the gate and the source. In order to increase the absorption range, the source and drain contacts (5, 6) consist of a finger-shaped, interlocking comb structure. Alternatively, the channel region is composed of two layers. A lightly doped layer is designed to pass charge carriers generated by light to a second, more heavily doped layer, the active channel layer. The second, more heavily doped layer is smaller in size, and arranged thereon are strip-shaped source and drain contacts. The structure of the optical field effect transistor provides easy integration with other components. <IMAGE>
