Abstract: An electroluminescent device includes a semiconductor layer (4) in the form of a thin dense polymer film comprising at least one conjugated polymer, a first contact layer (5) in contact with a first surface of the semiconductor layer, and a second contact layer (3) in contact with a second surface of the semiconductor layer. The polymer film (4) of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer so as to render the second contact layer positive relative to the first contact layer charge carriers are injected into the semiconductor layer and radiation is emitted from the semiconductor layer. The polymer film can be poly (p-phenyenevinylene) [PPV] of formula (I) wherein the phenylene ring may optionally carry one or more substituents each independently selected from alkyl (preferably methyl), alkoxy (preferably methoxy or ethoxy), halogen (preferably chlorine or bromine) or nitro. A method of manufacture of an electroluminescent device includes steps of depositing a thin layer of a precursor polymer onto a substrate and then heating the precursor polymer to a high temperature to form the conjugated polymer.

Abstract: The invention relates to a method and a device for the generation of a synchronous pulse pattern with fractional pulse numbers (p) for controlling an invertor of an intermediate circuit converter. According to the invention, a fractional pulse number (p) is determined as a function of the maximum permissible pulse frequency (fpmax) and of the basic frequency nominal value (f1), for which a next-lower and a next-higher pulse number (pu, po) are selected, an interval number (i) of the cycle duration (dz), a number of the intervals (iu) having the next-lower pulse number (pu) and a number of the intervals (io) having the next-higher pulse number (po) are determined as a function of these pulse numbers (p, po, pu), and the intervals (iu) of the next-lower pulse number (pu) are combined with the intervals (io) of the next-higher pulse number (po) within one cycle duration (dz). In consequence, a method and a device are obtained by means of which the utilisation of the maximum permissible pulse frequency (fpmax) is possible even in synchronous pulse operation. <IMAGE>

Abstract: A system is disclosed for recording and reproducing a luminance signal (Y) on and from a medium (40). The system includes an adaptive deemphasis circuit (10) for adaptively reducing the level of a high frequency portion of the luminance signal (Y). A record circuit records the reduced level luminance signal on the medium (40). A playback circuit reproduces the reduced level luminance signal from the medium (40). A reemphasis circuit (70) non-adaptively boosts the level of the high frequency portion of the reduced level luminance signal to produce the luminance signal (Y). To this end, a circuit (73) cores a high frequency portion of the reduced level luminance signal, and the level of the cored high frequency portion is then boosted by a predetermined amount to produce the luminance signal (Y). <MATH>

Abstract: The box-like package made of a thermoformable plastics sheet being of a one-piece, punched blank provided with folding scores. Supporting profiles are molded out inwardly or outwardly from individual regions of the blank by means of thermoforming. These supporting profiles resiliently support the packed product which is susceptible to shock; they are therefore preferably adapted to the contours of the product. The entire pack, including the supporting profiles, forms a single part, so that additional supporting inserts are superfluous. The most important advantages: saving in packaging material, dispensing with troublesome to handle additional inserts, good stackability of the sheets before assembly, readily recyclable monomaterial package.

Abstract: There is disclosed an inbound/outbound call handling system and method in which outbound calls are automatically paced so that as attendants become available a valid call is completed to be handled by the available attendant. As an inbound call is received, the system responds by halting attempts to place an outbound call and queueing the inbound call for handling by the next available attendant. The system takes advantage of an algorithm which statistically monitors average call completion time, average attendant in-use time, average time to answer and probability of a valid answer. Call placing and receiving overlap is controllable in conjunction with the monitored statistical parameters to achieve operation around any desired system operating parameter. The system is controlled by a plurality of precisely defined operational tasks operating in a hierarchical manner. <IMAGE>

Abstract: A cephalosporinase testing agent comprising a cephalosporin antibiotic such as cephaloridin, a penicillinase inhibitor in an amount of 20 wt% or less based on the antibiotic, and a pH indicator such as bromocresol purple. A cephalosporinase producing bacterium can be judged by smearing a sample containing a test bacterium on the testing agent and observing the color tone change. According to this agent, a cephalosporinase-active penicillinase producing bacterium is judged cephalosporinase-negative by the action of a penicillinase inhibitor such as clavulanic acid. Therefore only a cephalosporinase producing bacterium is judged cephalosporinase-positive. Thus this agent is useful since it is free from misjudgment.
