Title: Contact prodn. in semiconductor device with multiple wiring layers - using reactive metal film in contact hole between two aluminium layers to prevent faults
Inventor: INAYOSHI KATSUYUKI DIPL ING
IPC: H01L23/532
Filed: 1978-05-31
Abstract: In the prodn. of a semiconductor device with a first wiring layer, mainly of Al, on a first insulating film, a second insulating film is formed on the wiring layer, contact hole(s) are formed on this and a metal film, which reacts with Al, is formed on the first wiring layer in the contact hole(s). A second wiring layer, mainly of Al, is formed, at least in the contact hole(s), to cover this metal film and the first wiring layer and the metal film are reacted by heating the substrate. Devices with multiple wiring layers can be produced without great expense and without faulty connections between the upper and lower layers. The technique is useful in the prodn. of highly integrated circuits.

Title: Plastics roofing strip with turned over edges - has resulting beading with differentiated spacing to obtain end sleeve effect
Inventor: WEINHOLD JOACHIM DIPL ING
IPC: E04D3/38
Filed: 1978-06-14
Abstract: Plastics strip used in roofing work, esp. as gutter or 'valley' strip has beaded (i.e. turned-over) edges so that the turned-over margin is at a certain spacing above the rest of the strip. A 1st section of beading extending over part of the length of the strip is spaced more distant than a 2nd section above the central section of the strip. As a result, the thus-shaped strip has a sleeve-like end. The difference between the spacings amounts to at least the thickness of the unbeaded strip. The spacing different is maintained over at least a 200 mm long section of the strip. The prod. has a cross-section of Shape.

Title: Non-slip surface for sea going transport - produced by stripping off incompatible fabric moulded with synthetic resin surfaced component
Inventor: ZIMPFER MARKUS
IPC: B29C59/02
Filed: 1978-10-05
Abstract: A woven fabric or a gauze of e.g. polyamide is used to produce a non-slip surface on moulded components, esp. for use at sea. The fabric used is of a material which is unrelated to an cannot form a mechanical or chemical bond with the material which is to constitute the non-slip surface or be dissolved by it. The fabric or the gauze may be applied to the component the surface of which has a fluid coating material such as a polyester resin, or the fabric may be soaked with the polyester before application to the surface or before positioning in a mould. When the polyester resin has fully hardened off, the fabric or the gauze is stripped of the surface and leaves behind a finely structured non-slip surface. This is equally effective when wet or dry, it can be walked on in bare feet and cannot cause an injury in the case of a fall.
