Abstract: The tuning, switching and operating information items transmitted by means of the radio data system in parallel with the broadcast program in some cases require a country-specific evaluation since the transmission characteristics and the operating ease of an RDS broadcast receiver can only be optimised by adaptation to the transmission and language situations of the respective country. To avoid having to produce a multiplicity of country-specific set variants for the export of the set, an RDS broadcast receiver, particularly an RDS car radio, is disclosed in which the country-specific evaluation or indication of the information items contained in the RDS data signal occurs automatically as a function of the country code received together with the PI code. <IMAGE>

Abstract: The method is to determine a leak (10,11) in a breast wall of a regenerative heat recuperator having a combustion chamber (2) and a heat storage chamber (3) containing a heat storage medium adjacent to the combustion chamber and separated therefrom by a breast wall (4). The combustion chamber has inlet means (6,7) for fuel and air and the heat storage chamber has outlet means (9) for the flue gases which pass into it from the combustion chamber. To achieve a simple and accurate determination, the method comprises the steps of
     (i) while passing gas through the recuperator, introducing to the inlet means (6,7) a marker gas which undergoes an irreversible change at a temperature prevailing in the recuperator, and   (ii) detecting the presence of the marker gas in the gases passing out of the outlet means (9).

Abstract: A wire dot printer has a thermistor that detects the temperature of a print head (1) and a counter (5) that starts counting when the detection temperature exceeds an alarm temperature. The printer can be controlled by switching over between normal-printing and reduced-character-printing in which a reduced number of print wires is used. 
     When the detection temperature exceeds the alarm temperature, the printer will first stop and then control the print head (1) in such a way as to reduce the temperature. Once the temperature drops back down below the alarm temperature, the printer will perform reduced-character-printing for a definite period of time based on the length of time from when the temperature exceeded the alarm temperature to when the temperature dropped back down below the alarm temperature. 
     By increasing the length of time in which reduced-character-printing is carried out, the amount of heat given off by the print head (1) decreases. Furthermore, by basing the time over which reduced-character-printing is performed on the length of time that the alarm temperature was exceeded, it is possible to set the reduced-character-printing time to an appropriate length such that the print head (1) does not overheat and throughout is not excessively impaired.

Abstract: Devices are described in which certain crosslinked silicone polymers are incorporated. These polymers have various functions such as encapsulating agents, surface protective agents or agents to index match optical components (e.g. optical fiber, optical waveguide, etc.) to other optical devices or articles. The polymer is a vinyl-terminated dimethyldiphenylsiloxane copolymer crosslinked with tri-or tetrafunctional silanes in the presence of a platinum catalyst. The phenyl group content of the crosslinked silicone copolymer is adjusted to change the index of refraction of the polymer to the optimum for the particular application contemplated. Polymer preparation procedures are described which yield good optical quality for the polymer as well as optimum physical and chemical properties.

Abstract: When forming a metallization layer(13) in integrated-circuit semiconductor device fabrication, metal such as tungsten, for example, adheres poorly to dielectrics(11) such as, e.g., silicon oxide, and tends to flake off from wafer areas not covered by a glue layer(12)-- such areas typically including the backside and the edge of the wafer, and clip marks on the face of the wafer. The invention prevents flaking by processing including: forming an adhesive or glue layer(12) on the dielectric(11), forming a metal layer(13), forming a protective layer(14) on metal(17) on the glue layer(12), and etching to remove metal(13) not covered by the protective layer(14).

Abstract: A cache tag memory device has a dual port memory array for containing cache tags. One port, accessed by a local processor, can read from and write to the array. The other port is accessed through a global system bus, and can only read the memory array. A storage bit associated with each entry in the array is used as a valid bit. A cache tag entry match can never be made when such valid bit indicates that the entry is invalid. Both ports operate asynchronously from each other. The local port operates much like as SRAM during write and read operations. The global port always monitors the system bus, or snoops, and compares internal RAM data to the external system address. If an entry matches a system address during a system write operation, the corresponding valid bit is set to a value which indicates that the entry is invalid.

Abstract: Operational amplifiers (6r, 6b) detect deviations from white in pictures picked up based on color-difference signals (R-Y, B-Y) and generate white balance control signals, respectively. The data that correspond to the generated white balance control signals are held at counters (9r, 9b). The data that should be held at the counters (9r, 9b) are updated successively according to a synchronization signal which is applied successively to the counters (9r, 9b). Gains of variable gain amplifiers (3r, 3b) that amplify red and blue color signals (R, B) are controlled, respectively, based on the date held at the counters (9r, 9b). A color temperature detection circuit (19) detects a difference between a level of white balance control signal and a level expressed by the data held at the counter and generates a color temperature variation detection signal when the difference exceeding a predetermined level exists. In the event the color temperature variation detection signal is generated, a synchronization signal whose cycle is shorter than a cycle of synchronization signal that has been applied until that time is applied to the counters (9r, 9b) for a predetermined amount of time to accelerate the speed of updating data that should be held at the counters (9r, 9b).

Abstract: Flexible cuvettes are known for testing for DNA by allowing polymerase chain reaction amplification to take place therein. However, with these cuvettes, there is a risk that amplified DNA may leak into the atmosphere and contaminate the unused cuvettes in the vicinity. A further risk is that temporary seals may leak flow prematurely to the rest of the cuvette. Described herein is a cuvette (110) and a method for sealing off a passageway (121) extending from, e.g., an access port (122) in the cuvette (110) with closure means (184, 200) to ensure a complete seal is achieved. The closure means (184, 200) is joined to the rest of the cuvette (110) along a hinge line (190) which passes through the passageway (121) so that application of the closure means (184, 200) by bending the cuvette (110) about the hinge line (190) pinches off the passageway (121).
