Patent EP-0299686-A2 (EP)
Inventor: LEVI ANTHONY FREDERIC JOHN
IPC: H01L29/205
Filed: 1988-07-07
Abstract: An improved compound semiconductor hot electron transistor (HET) having room temperature current gain β 10 is disclosed. Disclosed are also means by which improved HET performance can be obtained. Among these means is choice of the base layer (12) material such that the hot electrons injected into the base have k i,2 /k i,1  0.2, where k i,1  and k i,2  are the components of the electron wave vector respectively normal and parallel to the interface, between the emitter (ii) and the base. A further means is choice of collector (13) material such that the hot electron velocity component normal to the base/collector interface remains relatively unchanged upon passage of the hot electron through the base/collector interface. For instance, an appropriate superlattice in the collector region may be used to achieve such matching. Causing quantization of the ambient charge carrier states in the base can reduce hot electron scattering in the base. In bipolar HETs such scattering can also be reduced if the effective heavy hole mass in the base is much larger (e.g., x10) than the effective electron mass in the forward direction. A strained base layer may be used to achieve this.

Abstract: An electric lamp having a coiled filament and at least one intermediate filament support which effectively restrains the filament from excessive swaying or sagging whereby premature lamp failure because of electrical shorting of the filament or thermal shocking of the glass envelope is substantially reduced. The intermediate filament support includes at least one flat segment interposed between two adjacent turns of the outermost coil of the filament. The maximum thickness of the flat segment is less than the winding separation of adjacent turns of the outermost coil. In preferred embodiments of the invention, the intermediate support encloses but does not grasp the filament so that no coil of the filament, inner or outer, is distended in the process of closing the support about the filament. A support in accordance with the invention effectively restrains filament movement in directions along and normal to the filamentary axis. The invention may be employed, singly or in multiples, in any incandescent lamp or any lamp employing an incandescent filament and is particularly appropriate for filaments designed to operate at relatively high voltages as is the situation in many European applications.

Abstract: A method and a device for clamping plane instable parts for subsequent machining are proposed. Here, the workpiece to be machined is secured radially and axially against the bearing surface of the clamping device and, after its radial centring on the surface remote from the surface to be machined, is supported at a multiplicity of locations over a minimum area or in a point-like manner. In this axially supported position of the workpiece, a tensile force is applied in the direction of the clamping device in order to fix the workpiece at at least one surface section of small area. The clamping device has axially movable bolts and devices acting over a small area for applying tensile force to the surface remote from the workpiece surface to be machined. During the machining of the workpiece, the bolts, each covered by the workpiece, are placed against the surface for the purpose of support and are fixed in this positive-locking position, while a tension means for axially fixing the workpiece is in engagement with the latter. <IMAGE>

Abstract: A permanent non-erasable memory (16) stores formatting data and command bit patterns for a plurality of devices of different categories manufactured by different manufacturers to be controlled by the remote control transmitter incorporating the memory. To select the correct format, the user activates an enter initiate key, thereafter a key to indicate the category of the selected device, and thereafter two digits which together signify the manufacturer and model number. The keyboard output signals resulting from activation of tne keys are stored in RAM (44) in the microprocessor (10) controlling the remote control transmitter's operation. The stored values in RAM constitute an address for the memory. Under microprocessor control, the data read out from memory is then applied to the transmitter driver circuit (29) to cause the properly formatted device control signal to be transmitted.

Abstract: An aqueous wash solution is buffered to a pH of from 5 to 9 and contains at least 1.5 weight percent of a compound comprising a lower alcohol sulfate anion having from 6 to 10 carbon atoms and an alkali metal or ammonium cation, such as sodium decyl sulfate. This wash solution is useful in a method for the determination of an immunological ligand, and is not prone to crystallization at lower temperatures. Particularly, it is useful for washing the immunological complex formed between the ligand and a receptor molecule therefor. Unreacted materials can be readily separated from the complex by the washing, particularly if the separation is carried out using a filtration membrane in a test device. A test kit for ligand determination com­prises the wash solution as well as one or more receptors for the ligand, at least one of which is labeled for detection. This kit is particularly useful for measuring human chorionic gonadotropin (hCG) as an early indicator of pregnancy.

Abstract: An assay device (10) and method for determining the concentration of an analyte in a fluid sample. The device includes at least two reaction zones (18, 20) which receive a fluid sample, and each reaction zone includes the same signal-generating components for converting an intermediate reaction product to a detectable reaction product. Where the intermediate product is H₂O₂, the signal-generating components may further include a trapping compound which competes with the substrate of the detectable signal product, to produce a silent reaction product, proportionately reducing the amount of detectable reaction product produced. In an embodiment of the device containing two reaction zones, the signal generated in the second zone is used to construct a standard curve which corrects for reduced-signal effects related to loss of reagent activity and linear inhibition effects. In an embodiment containing three reaction zones, the signal products generated in the second and third zones are used to construct a two-point standard curve which corrects for reduced-signal effects related loss of reagent activity and non-linear inhibition effects. The signal value from the first zone in each embodiment is plotted on the standard curve, to determine a corrected analyte concentration value.
