Patent DE-3366507-D1 (DE)
Title: Method of forming electroconductive domains in integrated monolithic semiconductor devices, and high package density semiconductor device manufactured by said method
Inventor: PERCIVAL RICHARD
IPC: H01L23/52
Filed: 1983-02-09
Granted: 1986-11-06
Abstract: In the manufacture of semi-custom integrated circuits silicon wafers with P and N or N and P structures are used, and interconnections to establish a specific application must be created. Unlike currently known technologies, electrically conductive film with standardized openings made according to a pre-arranged raster must be deposited on the silicon wafer. Subsequently the conductive film, will be removed from between the openings directly or indirectly by means of electromagnetic radiation in order to produce the required circuit configuration. A laser beam is particularly appropriate for this since it can be positioned and controlled, and can be used directly for the exposure of a photosensitive film. The creation of insular conductive film is then achieved through a photo- etch technique. By use of this process, an expensive customer specific photo mask can be avoided. A semiconductor device manufactured according to this process exhibits in its conductive film a regular arrangement of openings which are able to form the ends, sides or corners of insular conductive film.

Title: Method for manufacturing synthetic material objects
Inventor: ABRAMOV VSEVOLOD
IPC: B29C45/00
Filed: 1984-09-28
Granted: 1988-05-19
Abstract: The objects to be manufactured, particularly from partially crystallized plastic material are obtained by injecting liquid plastic material into a mould cavity through a feedhead; the plastic material is then allowed to cool and is removed from the mould. In order to obtain objects having a highly orientated crystalline structure without the need to apply extreme pressures, the temperature of the flowing plastic material during the injection operation is maintained at the most 50<o>C above the melting point of the material or above the temperature at the start of the melting and a pressure is used at the beginning of the injection which is comprised between 1400 and 2000 bars, which pressure is maintained until the pressure inside the mould cavity falls down to a very small value following the solidification of the synthetic material. The feedhead is kept permeable and the pressure in the cavity is measured, preferably after the feedhead.

Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (10) having a plurality of spaced glass cores (12,13) extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The preform is heated and stretched to form a glass rod (20) which is then severed into a plurality of units (21). Heat is applied to the central region (23) of each unit while the ends of the unit are pulled apart to elongate the taper inwardly the heated central region. The unit is then provided with a plurality of optical fibers (69, 70, 75, 76°, 82, 83; 89), one of which extends from each of the cores at the endfaces of the unit. A preferred method of providing the optical fibers involves forming the coupler preform of a matrix glass (46) that is easily dissolves in a solvent. Each of the fiber cores within the matrix is surrounded by a layer of cladding glass (54) that is relatively resistant to disolving by the solvent.

Abstract: Folding tables on passenger seats are usually hinged to the underframe of the passenger seat with two lateral struts. As a result, when the table plate is folded down not only is the leg-room of the passengers restricted but also there is a very large risk of injury in the event of an accident. In order to remedy this, it is proposed to attach the table plate to the underframe of the passenger seat solely by means of a single central strut. <IMAGE>
