Abstract: An electronic control device for providing control signals having direction and magnitude represented by electrical output signals operates by sensing relative changes in capacitance. The device utilises circuitry requiring only a few volts excitation at a suitable frequency. In operation of the device, a finger touch unbalances the equilibrium between a pair of capacitance electrodes C₁, C₂ which by means of the circuitry selectively produces signals representative of magnitude and direction, and whose value is proportional to the degree of imbalance, and which signals are used for vector control purposes. The electrodes C₁, C₂ are positioned in recessed slots 20, 22 in a casing 12, which slots are accessible by fingers. The capacitance electrodes C₁, C₂ are protected by a dielectric layer 24.

Abstract: An electrodynamic transducer (1) for use in a loudspeaker system for converting an n-bit digitized electric signal (11) into an acoustic signal comprises  n  voice-coil devices (4.1, 4.2, ... 4.n) which cooperate with a magnet system (3). The voice-coil devices each comprise a conductor whose length is the same for all the voice-coil devices. The areas of the perpendicular cross-sections of the conductors increase each time by a factor of two starting from the voice-coil device (4.n) corresponding to the least significant bit and going to voice-coil devices corresponding to consecutive more sig­nificant bits. In accordance with the invention steps are proposed which enable such a transducer to be con­structed in a simple manner if the transducer is a ribbon-type loudspeaker.

Abstract: A mechanical quantity sensor element making use of a stress-magneto effect of noncrystalline magnetic alloy. This mechanical quantity sensor element is manufactured by coupling a piece of noncrystalline magnetic alloy having positive magnetostriction with another material such as, for example. thermo-setting resin at a temperature exceeding an operating temperature range of the mechanical quantity sensor element. and then cooling them to the operating temperature range. Due to a difference in a coefficient of thermal expansion between the piece and the material, compression strain is preliminarily given to the noncrystalline magnetic alloy piece, and the mechanical quantity sensor element has an excellent linearity and a wide detectable range for mechanical quantities.

Abstract: A purified thermostable enzyme is obtained that has unique characteristics. Preferably the enzyme is isolated from the  Thermus   aquaticus  species and has a molecular weight of about 86,000-90,000 daltons. The thermostable enzyme may be native or recombinant and may be used in a temperature-cycling chain reaction wherein at least one nucleic acid sequence is amplified in quantity from an existing sequence with the aid of selected primers and nucleotide triphosphates. The amplification process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers, extending the primers with a thermostable enzyme to form complementary primer extension products which act as templates for synthesizing the desired nucleic acid sequence, and detecting the sequence so amplified. The steps of the reaction can be repeated as often as desired and involve temperature cycling to effect hybridization, promotion of activity of the enzyme, and denaturation of the hybrids formed. The enzyme is preferably stored in a buffer of non-ionic detergents that lends stability to the enzyme.

IPC: H04B10/00

Abstract: The present invention relates to a multiple-user communciation system wherein one carrier source (10) is shared by a cascade of users of the system. More particularly, the present communciation system uses a single carrier propagating along the system's transmission medium (11) onto which each user directly impresses the associated data or communciation signal destined for another user preferably using either subcarrier angle modulation (phase or frequency) or TDM techniques for intensity or angle modulation. In the present system using subcarrier angle modulation, each user can either transmit or receive at a fixedly assigned or selectively assigned subcarrier channel, which is different from the subcarrier channel assigned to each of the other users. Where TDM techniques are used, the communication signal from a user can be directly impressed on the single carrier using intensity or phase modulation. With such communication system, amplifiers (18) can be liberally used along the transmission medium with no inter-modulation distortion since the amplifiers see a constant envelope signal. The use of amplifiers solves the problem of excessive signal loss incurred when multiple users tap into or out of, for example, an optical fiber bus.

Abstract: The invention describes a method and a device for body protection against mosquitoes, in which, depending upon the fluid used, the insects deterred by that fluid are driven off. This is achieved by a method whereby a container (1), which is worn on the body, for example as an amulet or the like, is filled with a specific fluid for the insect which it is desired to repel, and is released to the environment as a protective vapour via slots (2) and holes provided in the container. The distribution of the vapour which deters the insect is then further reinforced by the wearer's body temperature. <IMAGE>
