Title: Liq. crystal display with capacitive-resistive coupling element - uses electrode of tantalum and dielectric of tantalum-pent-oxide between indium-tin oxide electrode contacting liq. crystal
Inventor: HOCHHOLZER VOLKER DIPL ING
IPC: H01L45/00
Filed: 1989-09-08
Abstract: The switching elements, used for active control of image elements in liq-crystal displays, consist of a base electrode, dielectric and counter electrode. The mfg process consists of the following steps: forming a pattern in a Ta-layer (12) deposited on a transparent substrate (10) by etching, pref forming a tapering edge, anodic oxidn of the Ta-layer to form the dielectric layer Ta-pentoxide, first annealing in vacuum, pref for 1 hr at a temp of at least 150 deg C, sputtering of the counter electrode (18), pref In-Sn-oxide, second anneal in oxygen ambient, pref in air for about 1 hr at 250-380 deg C, forming the overlap of the 2 electrodes by defining a photo resist pattern using irradiation of the resist layer, pref udner a sharp angle, through the transparent substrate, etching the counter electrode pattern. Also claimed is the use of a second dielectric layer, pref transparent, pref of Si-oxide, -nitride or -oxynitride, deposited after the first anneal. USE/ADVANTAGE - The process results in a capacitive layer with a defined voltage-current characteristic which can be adjusted by modification of the second anneal. This characteristic is symmetrical wrt polarity and  contains a low conductivity region with a width dependent on the second anneal temp. The steepness of the current characteristic above this voltage depend son the dielectric thickness. The process allows these parameters to be adjusted independently and can be easily integrated with the liquid crystal mfg process.

Inventor: RAIMER JUERGEN DIPL ING
IPC: B61L21/04
Filed: 1990-03-29
Abstract: If certain key-operated relays (for example E1 or G1) of a controlling unit must be locked against operation from the operating stations (BP1) or against operation via an automatic mechanism (ZL), corresponding locking markers are stored in the memories of two microcomputers (MC1, MC2) which convert the process control orders of the operating stations and of the automatic system into commands for switching on key-operated relays. During each operating action, the microcomputers check whether a locking marker has been stored for the associated key-operated relay. If this is so, they deny their permission for execution of the command and in the other case they grant relevant permission. <IMAGE>

Title: Yarn quality measurement - uses adjustment parameters for yarn faults to give cleaning profile and anticipated number of cleaning operations
Inventor: AEMMER PETER F DR
IPC: G01N33/36
Filed: 1990-06-22
Abstract: Quality of a yarn in terms of the type and number of yarn faults is determined, to establish the boundaries for the yarn cleaning system. The adjustment parameters for the reference length (x), sensitivity (y) are set according to the number (z) of cleaning actions to give the cleaning profile (RP), which shows the fucntional correlation between the number of all theoretical possible combinations of the adjustment parameters and the cleaning operations. The number of cleaning operations to be anticipated can be derived. The three parameters (x,y,z) are carried each on an axis of a three-dimensional and pref. Cartesian coordinate system. The cleaning profile (RP) is formed by a surface adjacent to one of the positive coordinate half-axes. Separate support values are produced by measurement to give the cleaning profile (RP) and the intermediate values are calculated by interpolation. The support value measurement is by a simultaneous virtual cleaning of all the support values of a given pair of adjustment parameters.  The yarn signals are compared with a number of classification boundaries, where each breach of a classification boundary registers a virtual cleaning operation and each classification boundary corresponds with a support value. The presentation of the cleaning profile (RP) is by three-dimensional graphics, a coded normal projection, a table with the support values in the separate fields, or curves each with the same itnersection frequency. ADVANTAGE - The method supports the virtual cleaning of yarns to remove faults in a productive, flexible and trouble-free system.
