Patent EP-0778681-A2 (EP)
Inventor: WEGENER REINHARD
IPC: H04B10/588
Filed: 1996-09-11
Abstract: The circuit (16) serves a modulator (5) constituted by e.g. a Mach-Zehnder interferometer. The electrical signal (UIN) is applied to a 180 degree hybrid, or antiphase power splitter (2a) whose outputs are applied through the distortion elements (1) and amplifiers (2b) to the modulator. Each distortion element, which may be a Mach-Zehnder modulator, achieves a partial serial development of the inverse of the transfer function. A variant embodiment has in each channel, phase and antiphase, a power splitter with one output delayed and the other cross-coupled, via a Mach-Zehnder modulator, to a combiner in the other channel.

Abstract: In forming a plano-convex lens from a column-like lens blank by heating the blank to a temperature higher than the transition temperature thereof and by pressurizing an upper die with a closed space formed between the blank and the upper die, there are alternately repeated operations of pressurizing the upper die and stopping the application of pressure thereto. Through the control of the amount of displacement of the upper die, the maximum pressure of gas in the closed space at each pressurizing step is so controlled: as to be low according to the surface viscosity of the blank to the extent that no local concave deformation in the surface of the blank is produced; and as to be high to the extent that gas caught in the closed space is discharged at each step of stopping the application of pressure.

Abstract: A communal electricity metering system supplies electricity to consumer sites via metering sites which each comprise a number of separate metering and measurement devices, and a common control unit. The control unit stores credit data for each consumer site, and monitors the consumption of electricity at each site, interrupting the supply when the respective credit is exhausted. Display units at the consumer sites communicate with the control unit, which transmits status data to each display unit. In addition, a consumer can use the display unit to communicate with a central control station via the control circuit at the metering site, via a combination of mains-borne and radio communication, to purchase additional credits and to receive confirmation of the entering of such credits at the metering site.

Abstract: Eine Galvanikanlage weist einen Galvanisierbehälter und einen Versorgungsbehälter auf, zwischen denen der Elektrolyt zirkuliert. Im Versorgungsbehälter erfolgt dabei die Ergänzung des Metallgehaltes des Elektrolyten durch eine lösliche Anode, der eine Hilfskathode zugeordnet ist, die sich in einem Hilfskatholyten befindet, der vom Elektrolyten über ein metallionen-undurchlässiges Diaphragma abgetrennt ist. Die unlöslichen Anoden des Galvanisierbehälters befinden sich in einem Hilfsanolyten, der vom Elektrolyten über anionen-undurchlässige Diaphragmen abgetrennt ist. Der wesentliche Vorteil dieser Lösung besteht darin, daß unlösliche Anoden eingesetzt werden können, daß aber auch die für präzise Beschichtungen beispielsweise im Leiterplattenbereich unerlässliche Prozeßorganik eingesetzt werden kann. Eine besonders vorteilhafte Weiterbildung sieht vor, daß der Hilfskatholyt und der Hilfsanolyt in einem gemeinsamen Kreislauf geführt sind, wodurch sich gegenläufige Verschiebungen des pH-Wertes von Hilfskatholyt und Hilfsanolyt durch deren kontinuierliche Vermischung weitgehend kompensieren.

Abstract: Highly concentrated waste water is subjected to a partially aerobic method in the reaction chamber of a vertical reactor (1). Aeration of the waste water is performed by regulating the redox potential. To this end, means (14) for measuring the pH value, on the one hand, and means (15) for measuring the redox potential value of the treated waste water, on the other hand, are arranged in a bypass line. The process computer acts via a regulator (31) on a regulating member (19) which regulates the supplied amount of air, and regulates the redox potential value according to the measured pH values in accordance with a predetermined relationship stored in a memory device (33). By means of regulating the redox potential by guiding the pH value, an essentially constant high rate of decomposition of 90% COD is achieved.

Abstract: The present invention is an apparatus for distributing
reactant gases across the substrate mounted in a reaction
chamber. The apparatus is capable of being utilized in
both vapor deposition and etching processes. The apparatus
substantially compensates for the problem of non-uniformity
of vapor deposition and etching at the edges of the wafers
caused by gas depletion. A gas distribution plate having
a plurality of apertures extending therethrough is attached
to an interior surface of the reaction chamber. At least
one vacuum sealed partition is disposed between a surface
of the gas distribution plate and the interior surface of
the chamber. The partition separates the space between the
plate and reaction chamber into gas distribution zones. A
gas inlet is connected to each gas distribution zone. Each
gas inlet line has at least one mass flow controller which
regulates the flow of gas to each gas distribution zone.
The mass flow controllers are utilized to ensure a uniform
rate of chemical vapor deposition or etching across the
surface of the substrate.

Abstract: A rear axle (10) which supports rear wheels (11) is attached to
the body of a vehicle in such a way as to be swingable up and
down around a center pin (10a). A controller (29) detects the running
state from detection values  and V of a sensor (21) for detecting
the tire angle of the rear wheels and a sensor (22) for detecting
a vehicle speed, and detects the load state from detection
values H and w of a height sensor (27) and a pressure sensor (28). When
a determination value derived from the detection values  and
V becomes equal to or greater than a set value which is
determined in accordance with the detection values H and w, an
electromagnetic changeover valve (14) of a dumper (13) is switched to
carry out control to lock the rear axle. When a sensor is
diagnoses as failing, maximum values max and Vmax or the like
are selected as most severe detection values. Even one of a
set of sensors fails, therefore, the rear axle will not be
locked as long as the vehicle runs in such a way that the
detection value of the other sensor allows the determination
value to be smaller than the set value.
