Patent EP-0413282-A2 (EP)
Inventor: OGLE JOHN SELDON
IPC: H01J37/32
Filed: 1990-08-11
Abstract: An apparatus for producing a planar plasma in a low pressure process gas includes a chamber (12) and an external planar coil (20). Radiofrequency resonant current is induced in the planar coil which in turn produces a planar magnetic field within the enclosure. The magnetic field causes circulating flux of electrons which in turn produces a planar region of ionic and radical species. The system may be used for plasma treatment of a variety of planar articles, typically semiconductor wafers which are oriented parallel to the plasma within the enclosure.

Abstract: Optimised high-alkaline proteases which are suitable for use in detergent formulations are described. They are prepared by employing mutated DNA sequences of transformed microorganisms. These DNA sequences are obtained by starting from DNA sequences which code for the high-alkaline protease which is normally produced by Bacillus species, modifying these DNA sequences in defined positions by directed mutagenesis (point mutation) in such a way that the codon in which the point mutation is located now codes for an amino acid which is more strongly basic than the original amino acid. The original amino acids have been replaced in the resulting high-alkaline proteases by more strongly basic amino acids, preferably by the amino acids lysine or arginine. Synthetic oligonucleotides, DNA sequences, vectors and transformed microorganisms used to generate and obtain the optimised high-alkaline protease are likewise described.

Abstract: An apparatus in which shutters used to occlude the region of the platen not supporting the original document being reproduced are calibrated. After the fully open position (112 or 114) of the shutters is determined, the size (L×W) of each original document being reproduced may be determined. In calibrating the shutters, an original document having a predetermined size is positioned on the platen with one set of perpendicular edges thereof being located at a registration position. The shutters are moved from the fully open position to another set of perpendicular edges of the document. The distance (L′ or W′)that the shutters move between the open position and the edges of the document is measured. With this information, the distance (R or Q) between the open position and the registration position may be determined as a function (L + L′ or W + W′)of the size of the original document and the distance that the shutters move. After the location of the open position of the shutters has been calibrated, the size of other original documents may be determined. The original document of unknown size is positioned with one set of perpendicular edges thereof located at the registration position on the platen. The shutter is moved from the open position to the other set of perpendicular edges of the original document. The distance that the shutter moves from the open position (L′ or W′) to the edges of the document is measured and the size of the document (L or W) calculated as a function (R-L′ or Q-W′) of the shutter distance moved and the calibrated distance between the open position and the registration position.

Abstract: An elevator system employing a micro­processor-based group controller communicating with the cars ( 3 ,  4 ) using car position and velocity information provided by a "smart" primary position trans­ducer (SPPT) system to control the motion of the cars and assign them to handle passenger demands. The SPPT includes an input shaft coupled to a primary encoder disk. Coupled to the shaft through gearing are one or more encoder disks performing the function of turns counting, as well as additional functions. Each disk contains multiple tracks, and each of these tracks is sensed by a sensor, or, alternatively, the SPPT may use two independent sensors per track. It is important to have two essentially independent means of performing the key sensing functions. The read heads of the SPPT are divided into primary and secondary sets with each set used to feed an independent processor. Within each set of sensor signals, cross checks are performed to insure the integrity of the system, which would detect a cracked or broken glass disk. In the electronics of the SPPT system primary and secondary position signals are each found by two methods and compared to maximize the likelihood of correct position determination, with one method given priority over the other, depending on the circumstances. Two independent channels for position and velocity information are main­tained, using independent parts, except for the input shafts and encoder disks. Exemplary formulae for determin­ing and generating the desired primary and secondary position and velocity information are provided.

Dysfunction of the central 5-HT 1A receptors can be diagnosed by an azaspirodecanedione-induced prolactin response which is distinguishable from that observed in a subject with peptic ulcer disease and/or inflammatory bowel disease. A suitable azaspirodecanedione for inducing the prolactin response is buspirone.

Abstract: An electronic ballast for low-pressure discharge lamps supplied from DC or AC voltage networks, having an invertor (1) which supplies at least one lamp (8) via a capacitive reactance (6) connected in parallel with it and an inductive reactance (2) connected in series with it, an electronic harmonic filter (4) with a step-up inductor (L3) and a digital control circuit (2) for the invertor, which control circuit is connected to a DC voltage supply circuit (3). The DC voltage supply circuit is connected to the harmonic filter and has a capacitor (C3) which can be charged to the supply voltage of the control circuit via a first transistor (T4). The first transistor switches on immediately after the supply voltage of the electronic ballast has switched on. A blocking circuit (R6, R7, C4, T5) switches the first transistor off once the capacitor is charged and the latter is continuously recharged via an additional auxiliary winding (N1) of the step-up inductor and a rectifier circuit (D1-D4) connected thereto. In consequence, the voltage required to supply the control circuit is made available immediately after the start, in the case of both DC and AC voltage operation. <IMAGE>
