Patent DE-3209931-A1 (DE)
Title: Method for determining an envelope curve of a projection area which is covered by a vehicle when it moves through a curve, and template for an envelope curve
Inventor: HAMMER REINHOLD
IPC: G01B21/20
Filed: 1982-03-18
Abstract: The invention proposes a method for determining an envelope curve (17) of a projection area which is covered by a steerable vehicle (20) when it moves through a curve, in such a manner that the outside limit (21) of the vehicle is conducted at a particular predetermined curve line (12) and the trailing curve (19) of the envelope curve (17), which points towards the inside of the curve, is measured. For this purpose, reflectors (23, 24) are mounted on the side (22) of the vehicle (20) pointing towards the inside of the curve, the position of which reflectors is recorded at certain intervals along the distance travelled. The measurement data obtained are drawn to scale and the outside dimensions of the vehicle (20) are also drawn to scale in accordance with the position of the reflectors (23, 24). This results in successive pictures of the vehicle in accordance with its position when it moves through the predetermined curve (12). The trailing curve can be drawn by simply applying an envelope curve to the overlapping images of the outside vehicle dimensions pointing towards the inside of the curve. A further subject-matter of the invention is a template (26) which can be produced with the aid of the method described and which can be used when planning traffic systems for determining the area required for certain vehicles to travel in a curve. <IMAGE>

Patent DE-3303498-A1 (DE)
Title: Process for producing a semiconductor component
Inventor: ICHIKAWA NORIO
IPC: H01L29/84
Filed: 1983-02-02
Abstract: In a process for producing a semiconductor component, a layer containing a high concentration of phosphorus is formed on a silicon substrate by high-temperature deposition or chemical low-temperature vapour deposition, phosphorus contained in the layer is diffused into the substrate by a high-temperature heat treatment, and the phosphorus-containing layer is converted into a phosphorus silicate glass layer (PSG layer) which is suitable for passivation purposes. The PSG layer has a phosphorus concentration of approximately 10-20 mol-%, taking P2O5 as a base. The diffusion process and the passivation are carried out simultaneously, thereby reducing the number of manufacturing steps. It is not necessary to form an oxide film on the PSG layer, with the result that electrodes can be formed by simple etching and the reliability of the component is improved.
