Patent EP-0055203-A2 (EP)
Inventor: MORIARTY ROBERT MICHAEL
IPC: H02M7/527
Filed: 1981-10-30
Abstract: A selective commutation technique used with an inverter eliminates one of the two commutation pulses at those points at which there is a particular relationship of inverter operating characteristics. If the power factor angle 0, the voltage phase angle 6, and the voltage pattern notch angle are sensed to determine this particular relationship. Because at the switching point there is no current flowing througt the conducting thyristor, the conducting thyristor can then be transitioned to the nonconducting state merely by the removal of its gate signal. A single makeup pulse is then rung through the system to initialize the commutation capacitors for the next switch point.

Abstract: A method for using a hot water central heating system which is provided with a flue gas heat exchanger (6) disposed outside the hot water boiler (1) in the flue gas outlet between the hot water boiler (1) heated by an oil or gas burner (2) and the chimney. To achieve a substantially higher energy saving, on the one hand the water exchange between the hot water boiler (1) and the heat exchanger (6) is suppressed during the individual heating up phases associated with each heating cycle by means of a temperature-dependent or time-dependent control (25) and, on the other hand, the burner (2) is shut down during the heat exchange following each heating phase. In addition, a flue gas outlet flap (15) is provided in the heat exchanger (6) and is only open during the heating phases. To control the water exchange, a three-way switching valve (20) is provided with which the return line (4) of the heating system and one connecting line (17) of the heat exchanger (6) can alternately be connected to the hot water boiler (1). To achieve a rapid exchange of water, a feed pump (5) is provided. The burner (2) is shut down at the end of a heating phase whenever a predetermined upper temperature limit value is reached in the heat exchanger and the water exchange is shut down when equal temperatures are reached in the hot water boiler (1) and in the heat exchanger (6). <IMAGE>

Abstract: The invention relates to a capacitor feed-through, filled with dielectric fluid (8), in an open air configuration for high-voltage electrical apparatuses, especially for transformers and inductor coils. By means of the invention, a capacitor feed-through is produced, which is filled with dielectric fluid and requires little servicing, whose freedom from icing is ensured even in severe weather conditions, for example at a high wind speed and temperatures below 0 DEG  Celsius, especially also close to power station cooling towers. This is achieved in that the dielectric-fluid filled internal space of the feed-through, is connected via inlet and outlet openings (13; 14) in the flange fitting (3) to a circulation system consisting of tubes (24), heating elements (9; 11), a bypass line (22) with a switch-off device (23), and a circulation pump (12). <IMAGE>

Abstract: A data memory circuit (6) is provided including a plurality of depletion type MOS transistors (M20 to M23) connected in series, each of which stores data including two bits in the form of a threshold voltage. One end of the memory circuit (6) is kept at a power source level (V cc ) and the second terminal (3) thereof is kept at a ground potential level (V ss ). 0 V is applied to the gate electrode of one selected MOS transistor while the power source voltage is applied to the gate electrodes of the remaining MOS transistors. As a result, a voltage equal to an absolute value of the threshold voltage of the selected MOS transistor is produced at the second terminal (3). A converter (8) converts the voltage (E1) produced at the second terminal into corresponding binary coded data.

Abstract: A ground antenna (24) is located at a desired stopping position of a vehicle (21) along a vehicle track and extending over a predetermined distance (L 1 ), and the ground antenna (24) radiates a radio wave in a direction perpendicular to the vehicle track. The vehicle (21) has a plurality of receiving antennas (25, 26) mounted thereon along the direction of vehicle movement with an interval (L 2 ) less than the predetermined distance (L 1 ). Since each of the receiving antennas (25, 26) can receive the radio wave only when each receiving antennas (25, 26) is positioned within the range of the predetermined distance (L 1 ), a stopping position of the vehicle (21) is determined by discliminating which of the receiving antennas (25, 26) received the radio wave.

Abstract: An asymmetric RAM cell is disclosed which will have a predictable initial storage state when pulsed drain voltage is turned on and yet after the initial turn-on interval, will operate in a symmetric fashion storing either binary ones or zeros. Thus, an initial prestored set of information can be permanently provided in a memory array made up of such cells (1 and 2), by orienting each individual cell at the time of manufacture so as to selectively represent either a binary one or zero. This is illustrated in the figure where the upper cell (1) has a first state by virtue of its orientation and the lower cell (2) has a second, opposite state by virtue of its relative opposite orientation. When the array is turned on, the upper cell will have the opposite binary state from the lower cell. Thereafter, each cell can be respectively switched for storing ones and zeros in a normal RAM operating mode.

Abstract: A method for forming a self-aligning resist mask (14) over a surface of an alumina ceramic substrate (10) having a molybdenum or other metal pattern (12) at said surface. First, the surface is blanket coated with a negative resist (14) sensitive to aluminum-emitted X-rays. A blanket dosing of the substrate with resist-insensitive X-rays induces X-ray emission by the aluminum penetrating said resist. The aluminum X-ray emission is screened by said molybdenum pattern at the surface and the resist adjacent the surface molybdenum pattern is penetrated by the aluminum X-ray emission. The resist is developed for removal thereof over the molybdenum pattern while retaining the resist doped by said aluminum X-ray emission. Further metallization can be accomplished by evaporation or sputtering to blanket coat the developed resist with a conductive metal followed by removal of the resist with the metal coating thereon such that the metal coating is retained on the molybdenum pattern.

Abstract: A negative photoresist is formed from a photosensitized ("PS") composition having as an essential component, a homopolymer or copolymer having a major molar amount of a ring-opened unsubstituted tetracyclic norbornene ("NB"), and/or a substituted tetracyctic NB having non-polar substituents, and a minor amount, if any, of another NB, optionally also similarly substituted with non-polar substitutents. The negative photoresist formed by exposure of a film about 1 micron thick of the PS composition to ultraviolet light in the range from about 220-450 nanometers forms, in the contact mode, a pattern of lines and spaces which are developed in a substantially aliphatic hydrocarbon solvent so as to provide a high resolution in the range from about 1 micron to about 2 microns in the pattern.
