Filed: 1991-04-11
Abstract: For providing an avalanche photodiode having a good guard ring effect and a high speed response, a semiconductor body is prepared, which includes a window layer (26) of n-type InP epitaxially grown on an avalanche multiplication layer (25) of n⁺-type InP. The window layer is selectively removed so as to expose the avalanche multiplication layer, thereby providing a recessed portion (36). After a p-type impurity is selectively introduced into the window layer (26) to form a guard ring (28) therein, a p-type impurity is selectively introduced into both the exposed avalanche multiplication layer (25) and the guard ring (28) to provide a PN junction (35) therein.

Abstract: The invention relates to a method of destroying foam by separating it into its liquid and gaseous components under the action of centrifugal forces, the foam (35) being drawn in axially and then being accelerated radially (36) outwards under the action of the centrifugal force field and the gaseous component being discharged through a gas outlet (34), before the liquid component is ejected, with restriction, through an outflow (33). An apparatus for foam destruction has a fan wheel (7) and a gas outlet (33), the fan wheel being constructed as a pump wheel to be driven in rotation, with an axially arranged inlet and an outflow arranged in the region of the pump wheel periphery and constructed with a restriction, and a gas outlet arranged radially (17,16,15) between the inlet and outflow.

Abstract: For the microanalysis, in particular, of whole blood, serum or the like, the housing (12) of a module (10) contains a narrow measurement channel (14) to which extends an electrode (16). The latter has a screw head (20) with a terminal (24) which is detachably connected to a connector wire (28) leading to a sensor surface (48) while being mechanically self-centred in a contact zone (30). A centring tube (68) has an inlet opening (58) for a central conductor (32), which is optionally tapered, of the terminal (24) which fits over the free connector wire end (36) in a conducting manner in a blind hole (34). The end has an annular bead (38) which is formed without cutting. The connector wire (28) thickened in this way and gripped in a ring holder (66) of the electrode base (18) is trapped in the blind hole (34), which is preferably lined with solder (60), of the central conductor (32) which may be expandable at the bottom. A supporting section (50) protects the sensor area (48) at the base (18), which is sealed at a collar (46) by means of O-rings (44, 62) from the head (20) and the housing (12) and is held reproducibly and precisely by a step-type stop (40, 42). Opposite the sensor surface (48) in the measurement channel (14) is a symmetrical dome (54) formed by a transversely fitted plug (56). <IMAGE>

Abstract: A signal processing circuit is provided, such as a PIN diode attenuator for use in cable television signal distribution. The circuit includes a variable impedance device (52) that is responsive to an input signal. The input signal is provided over a first range to vary the impedance in response to a control signal (Vs) having an absolute value below a predetermined threshold. The input signal is provided over a second range in response to the control signal having an absolute value above the threshold. 
     The first and second ranges are not contiguous. In a preferred embodiment, a zener diode (48) is used to increase the drive current to a bridged-T PIN diode attenuator when the attenuator control signal reaches the zener breakdown voltage.

IPC: H03G3/30

Abstract: An amplifying circuit with a small current consumption. The operating current of a differential amplifier (A1), which is the main component of the amplifying circuit, is controlled by a first current circuit (7), which is a fixed constant-current source, and a second current circuit (A4), which is a variable current source. The current of the second current circuit (A4) is controlled by an input audio signal with the voltage subjected to full-wave rectification. As a result, when the amplitude of the input signal is small, only a slight operating current is consumed by the first current circuit (7), thereby saving electricity. On the other hand, when the amplitude of an input audio signal is large, the current of the second current circuit (A4) also increases therewith, so that the amplifier flows a sufficiently large output current. Thus, it is possible to amplify the current in correspondence with the amplitude of an input signal, while reducing the operating current when the amplitude of an input signal is small, thereby reducing the current consumption.

Abstract: A process for the preparation of optically active amino acid amide whereby a mixture of the L-amino and D-amino acid amides in the presence of 0.5-4 equivalents of an aldehyde, relative to the quantity of amino acid amide, in the presence of a solvent and water, is converted in whole or in part by means of an optically active carboxylic acid into a salt of the amino acid amide and the carboxylic acid, and a portion mainly consisting of one of the diastereoisomers of that salt is separated from the reaction mixture obtained. Instead of a mixture of L-amino and D-amino acid amides it is also possible to use a mixture of the Schiff bases of an amino acid amide and an aldehyde, in which case it is not necessary to add extra aldehyde, and the required quantity of water amounts to at least 1 equivalent relative to the quantity of Schiff base. With this process a high yield of optically active amino acid or the corresponding amino acid is rapidly obtained.

Abstract: Detection of variable nucleotide(s) is based on primer extension and incorporation of detectable nucleoside triphosphates. By selecting the detection step primers from the region immediately adjacent to the variable nucleotide, this variation can be detected after incorporation of as few as one nucleoside triphosphate. Labelled nucleoside triphosphates matching the variable nucleotide are added and the incorporation of a label into the detection step primer is measured. The selection of the detection step primer is important to the method according to this invention and is dependent on the nucleotide sequence of interest. The detection step primers are preferably selected so to span the region immediately toward the 3' end from the variable nucleotide to be detected. The method is useful in identifying specific point mutations and genetic variations.
