Abstract: 2. The electrical cigar lighter known from the prior art is still capable of improvement from the point of view of product design which is easy to fit since, when it is installed in the dashboards of motor vehicles, it does not permit a linear joint movement of a fitting robot. 
<??>3. Therefore, according to the invention it is essentially proposed to provide a cup-shaped clamping sleeve (1) which encloses the socket (2), which can be premounted in it, and has an arrangement of the lamp (9) and of the contact parts (5,6,7) near to the central axis. 
<??>4. As a result, a largely rotationally symmetrically constructed, illuminated electrical cigar lighter is provided which can be automatically fitted by means of a single linear joint movement.

Abstract: A reactance control circuit comprising a variable reactance circuit (14) whose reactance is determined by the currents flowing to first and second differential transistors (141, 142), a differential amplifier (12) for producing first and second currents (I1, I2) in accordance with an input voltage (Vin), and a DC ampli­fier circuit (20) for amplifying the first and second currents (I1, I2) and supplying the amplified currents to the variable reactance circuit (14) in order to control the currents flowing to the first and second differential transistor circuits (141, 142). The DC amplifier circuit (20) includes first and second transistors (Q1, Q2) for supplying output currents to the variable reactance circuit (14), and a base poten­tial control circuit (21) for, when the first and second currents (I1, I2) are equal to each other, sup­plying a predetermined low potential to the bases of the first and second transistors (Q1, Q2) so that the cur­rents flowing to the first and second transistors (Q1, Q2) are both reduced.

Abstract: The present invention is directed to an electrode construction of a battery (1) in an electrical equipment. According to the present invention, at least two contacts (8a, 8b; 5a, 5b) in an electrode (4, 7) have a different shape from each other, so that the characteristic frequencies of these contacts are dif­ferent from each other. As a result, when a contact is reso­nating by the frequency of an oscillation applied to the elec­trical equipment, the other contact keeps in contact with the battery (1) without resonating.

Abstract: In a satellite communications system, a unique word is transmitted from a central station at frame intervals to the satellite and broadcast to terminal stations. Blocks of data from the central station are composed into packets which are exclusively encrypted, and asynchronously transmitted to the satellite by giving priority to the unique word by interrupting the transmission of packets. A copy of data signals from the central-station data terminals is stored and retransmitted to a terminal station in response to a repeat request signal received therefrom. In each terminal station, the unique word is detected to generate a timing signal in response to which the encrypted packet is deciphered. The deciphered packets are decomposed into blocks of data, and sent to a destination data terminal. If there is an error in the decomposed packets, a repeat request signal is transmitted from the terminal station through a terrestrial link to the central station to cause retransmission of a copy of the stored version of the disrupted packet.

Abstract: A method of fabricating high speed, low leakage, radiation hardened integrated circuit semiconductor devices. In accordance with the method a SIMOX (separation by ion implantation of oxygen) wafer is masked with a separation mask to form silicon islands. The separation mask forms groups of N-channel and P-channel devices that are isolated from each other. The N- and P-channel device separation assists in preventing device latch-up. N- and N-channel devices are isolated by controlling the process due to high field inversion thresholds and radiation hardened field oxide to eliminate any channel-to-channel leakage current after high dosage irradiation. A relatively thin gate oxide layer is formed over the islands, and the island edges are covered with phosphoroborosilicate glass deposited at a relatively low temperature (850°C) to eliminate sharp island edges and hence edge leakage. The use of SIMOX substrate materials, phosphoroborosilicate glass and thin oxide provides the benefits of improved speed and reduced leakage due to intrinsic oxide isolation, shallow wells and source and drain junctions. The use of a thin thermal oxide layer and phosphoroborosilicate glass eliminates the edge leakage and channel-to-channel leakage upon high dosage irradiation, thus providing improved radiation hardness. The method of the present invention provides for devices having stable field behavior after irradiation. The method produces radiation hardened devices that exhibit high speed and reliability and which are stable when irradiated with up to a 10 MRad dosage level.

Abstract: An optical fiber (10) is proof tested by bending it relative to the fiber axis by a preselected amount, in all directions and at all locations along the length of the fiber. In one approach, the optical fiber is wrapped around a cylindrical mandrel (52) in a helical pattern and drawn over the mandrel through its entire length. With the preferred helical angle of about 45 degrees, two wraps of the optical fiber around the mandrel ensure that all of the fiber will be bent in all directions. If a flaw exists in the optical fiber that would cause failure at any amount of bending below that of the preselected amount, this proof test will cause the fiber to fail so that the weak point may be eliminated.

Abstract: There are described plasmids for the production of transgenic plants, and these plants which are altered by the transfer and the expression of genes which are located on these plasmids and which engage in the sugar metabolism or sugar partitioning within a plant. The transferred genes cause an altered distribution of photoassimilates in the transgenic plants, which results in substantial modifications in the appearance such as size, leaf shape, distance between the internodes and root production, and in modifications of the yield. There are furthermore described plasmids which allow foreign proteins to be directed in the vacuoles of transgenic plants.
