Title: Circuit for a controlled power converter.
Inventor: KUFNER HERWIG DIPL-ING
IPC: H02M1/12
Filed: 1990-09-06
Abstract: The operation of power converters places shift and distortion reactive power on the main power system. The interference currents thus generated can be short-circuited by impedance circuits, but this measure is not always sufficient. It is therefore proposed according to the invention to connect a controlled feedback auxiliary converter (2) using fast-switching semiconductors in parallel to a converter (1) on the input side. The actual value of the current measured on the input side is fed in both converters (1, 2) to an adding device (7, 8) connected to a current regulator (9, 10) which is connected in turn to a control (11, 12) for the converters (1, 2). A reference current interfaced via a multiplier (14) with a reference sine wave (15) which is synchronised with the a.c. voltage applied to the converters (1, 2) is taken to the adding device (7) for converter (1). The difference between the actual and reference values at this converter (1) is taken to an inverter (16), the output signal of which is taken to the adding device (8) for the auxiliary converter (2) as a reference value. Unlike tuned impedance circuits, this arrangement not only impedes certain frequency components in the interference currents but also facilitates the compensation of any shape of curve through the high switching frequency of the auxiliary converter (2).

Abstract: A DRAM cell having enhanced capacitance attributable to the use of a textured polycrystalline silicon storage-node capacitor plate (65). The present invention is particularly applicable to DRAM cells which employ a stacked-capacitor design, as such designs generally a conductively-doped polycrystalline silicon layer as the storage-node, or lower, capacitor plate. A poly texturization process imparts a three-dimensional texturized character to the upper surface of a first polysilicon layer (57). Texturization of this layer is accomplished by subjecting it to a wet oxidation step. Since oxidation at the crystal grain boundaries on the surface of first poly layer (57) proceeds more rapidly than elsewhere, the surface becomes bumpy. When maximum texturization has been achieved, the overlying oxide (59) is removed from first poly layer (57) during a wet etch step. With texturization complete, first poly layer (57) is patterned to form a storage node plate (65). A thin (70-100 angstroms thick) silicon nitride layer (67) is deposited on top of storage node plate (65), followed by the deposition of a second poly layer (69), which, after patterning, functions as the capacitor field plate. Since the nitride layer (67) is thin in comparison to the bumps on the surface of the storage-node plate layer, capacitive area is substantially augmented. Cell capacitance can be increased approximately thirty percent using a storage-node plate so texturized.

Abstract: A sedimentation centrifuge includes a bowl (2) which is supplied with a feed mixture, i.e., a solid-liquid mixture, from a supply pipe (1). When the bowl rotates at high speed, heavy solids are displaced radially outwardly toward and sedimented on the inner wall surface of the bowl. The solid particles are then discharged through a discharge hole of the bowl and an outlet passage (5) by a screw conveyor in the bowl. During rotation of the bowl, fins (7) on the screw conveyor assist in separating the liquid into heavy and light liquid phases with increased separation efficiency. The separated heavy and light liquids are separately discharged from the bowl through respective outlet passages (9),(11).

Abstract: A moisture-sensitive metal-oxide layer (2) is present on one side of a plate-type substrate (3), preferably composed of glass. Electrodes (4a, 4b) are situated on the side of the substrate opposite the oxide layer and each is connected to a terminal wire (6). The metal-oxide layer (2) and the metal coatings of the electrodes (4a, 4b) are applied to the substrate (3) by a thermal transfer method. The capacitive moisture sensor can be produced very simply without photolithographic operations, it has a very fast response time and it does not have any metal electrode parts on the moisture-sensitive layer (2) side. The sensor is therefore suitable for measuring microclimates. It can also be advantageously used in explosive environments. <IMAGE>

Abstract: A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone ocnduction. The hearing is believed to use channels of communications to the brain that are not normally used for hearing. These alternative channels do not deteriorate significantly with age as does the normal hearing channels. The supersonic bone conduction frequencies are discerned as frequencies in the audiometric range of frequencies.

Abstract: A pneumatic tire has an integrated circuit transponder which, upon interrogation by an external RF signal, transmits tire identification and tire pressure data in digitally-coded form. The transponder has an antenna adjacent and thereby coupled by electric or magnetic fields to an annular tensile member comprising a bead of the tire. The antenna has lead wires that preferably are positioned between the innerliner of the tire and its continuous carcass ply. The transponder thus is on the axially inner side of the reinforced carcass ply. A pressure transducer is within the transponder and is responsive, preferably through the innerliner material, to pressure within the tire. If the antenna is a coil, the coil is substantially planar in shape and parallel with the reinforced carcass ply. The transponder and pressure transducer also can be attached to the axially inner side of the innerliner.

Abstract: For the purpose of storing sensible heat, a regenerator, for example in a wind heater or a heat accumulator in a solar installation, has an accumulator core (1) made from ceramic or metallic or natural material. The accumulator core (1) is subjected for charging purposes to a hot charging flow from the hot side, until a maximum permissible exit temperature is reached on the other, cold side. For discharging purposes, the accumulator core (1) is subjected from the cold side to a cold discharging flow until a minimum permissible exit temperature of the discharging flow is reached on the hot side. In order to improve the heat-absorbing capacity for sensible heat without increasing the volume, there is arranged on the hot side and/or the cold side of the accumulator core (1) a layer (3, 4) which serves as a temperature buffer and disproportionately delays the maximum permissible exit temperatures from being reached, or disproportionately increases the heat-absorbing capacity. <IMAGE>

Abstract: First, wheat germ lectin (WGA) is coated to the bottom of each well in a U-bottomed plate. Erythrocyte is coated to the well bottom in a single layer to prepare a plate for coating erythrocyte. Next, to each well of this plate, a drying solution containing saccharose of 20 wt%, bovine serum albumin of 0.2 wt%, and sodium dithionite of 0.05 wt% is dispensed in 100 µℓ portions. After the plate was allowed to stand for three minutes, the drying solution was discarded and water is then removed. The plate for fixing erythrocyte was then air-dried by a dry incubator at 30°C for thirty minutes, and dried again under reduced pressure by a vaccum dryer. The plate for fixing coated erythrocyte is thus obtained, which has erythrocyte coated in a single layer in its well bottoms and fixed by drying. According to this method, the coated cells can be fixed with activation of specific substance maintained.
