Patent DE-4030108-A1 (DE)
Inventor: BRANDES BERND
IPC: G01N27/00
Filed: 1990-09-22
Abstract: A process is disclosed for assessing the quality of an object or state. In praxis, when the quality (G) of an object or state is compared with a comparison value (GV), there can be evaluation latitudes or discrepancies over the level of the acceptable comparison value (GV). The object of the invention is to develop a quality assessment process that largely avoids such evaluation latitudes and discrepancies and that makes it possible to better adapt the quality assessment to practical conditions. For this purpose, the comparison value (GV) is set at the beginning of the assessment slightly below the actual initial quality (GA) and remains constant during the assessment or automatically follows the value of the actual quality (G) in the direction of quality improvement but not in the direction of quality deterioration. Should the actual quality deteriorate, the comparison value can be set anew. The process is particularly useful for checking the humidity of the insulation of ducts in cable shafts and the like.

Patent DE-4108952-A1 (DE)
Inventor: HEIMERL ALBERT DR
IPC: A61B90/00
Filed: 1991-03-19
Abstract: The invention relates to a surgical fastener apparatus comprising two releasably connected apparatus parts (1, 2). A first apparatus part (1) designed as a disposable unit receives the magazine with the fasteners and tools for shaping and implanting the fasteners, whereas handles (4,6) for operation of the apparatus are assigned to the other apparatus part (2). During the operating phase relatively high forces develop which may lead to separation of the two apparatus parts (1, 2). This is prevented, according to the invention, in that a second connection (14, 15, 18, 19) is provided between the two apparatus parts (1, 2) in addition to the abovementioned first connection, which second connection is only effective during the operating phase.

Inventor: PFEFFERLE WALTER DR
IPC: C12P13/00
Filed: 1991-09-17
Abstract: The invention relates to a process for the fermentative production of amino acids, in which a strain of the genera Brevibacterium or Corynebacterium producing one or more amino acids is cultured in a nutrient medium and, at the end of the fermentation, the amino acid(s) is/are isolated from the culture fluid, which process is characterised in that following the strong growth phase the bacterial culture has less assimilable carbon source available than it could metabolise on account of the strain construction and of the amount of the otherwise necessary supplements provided in the nutrient medium.

Title: Chromium@ mask with phase-shirt coating for integrated circuit manufacture - formed by depositing layer on top of chromium@ which can be oxidised, using obtd mask during chromium@ etching and oxidising
Inventor: KIM HONG SEUK
IPC: H01L21/027
Filed: 1992-01-13
Abstract: The mask with phase-shift layer is mfd. as follows: a Cr-film (30) is deposited on a quartz-plate (10) and covered with an oxidisable material (40), pref. polycrystalline or amorphous Si. The 2 top layers are etched successively into the required pattern using a photoresist and an electron beam. The layer above pref. acts as the mask for the etching of each of the layers (40, 30). The top layer (40) is oxidised, causing a volume increase which leads to overhanging edges. The phase-shift layer is pref. a metal-oxide layer. The resist layer used is pref. an electron beam resist. USE/ADVANTAGE - The process produces a Cr pattern without the trapezoid shape of currently available masks. The overhang of the phase shift mask is well controlled and can be specified by the selection of the oxidisable material for its volume change. The process is very reproducible. The masks are used in the mfr. of integrated circuits, esp. for sub-micron dimensions.

Patent DE-4209524-A1 (DE)
Inventor: DOEMENS GUENTER DR ING
IPC: H01L21/00
Filed: 1992-03-24
Abstract: In order to determine the position and/or to ckeck the separation of the leads (A) of components (B), a shadow of the area provided with leads at one side of the component is directly projected onto the photosensitive surface of a local resolution optoelectronic transducer (W4). By successively projecting shadows from two different directions, the coplanarity of the leads (A) may also be checked.
