Abstract: An arrangement for converting an electric signal into an acoustic signal (y/t) or vice versa, comprises an electroacoustic transducer (2) and means (3) for reducing distortion in the output signal of the arrangement, which distortion is caused by the electroacoustic or acoustoelectric conversion performed by the transducer.The means comprise a non-linear network (3', 3" or 3'" in FIGS. 3; 43', 43" or 43'" in FIG. 4). The non-linear network is arranged for reducing non-linear distortion by compensating for at least a second or higher order distortion component in the output signal of the arrangement. The network may comprise at least two parallel circuit branches (15a, 15b in FIG. 3; 47a, 47b in FIG. 4). At least one of the circuit branches (15b in FIG. 3; 47b in FIG. 4) compensates for non-linear distortion of the second or higher order.

Abstract: A display device comprising channels (30, 30′, 30″) containing an ionizable gas (33), and walls of the channels (30, 30′, 30″) being provided with row electrodes (31, 32) for selectively ionizing the ionizable gas (33) during operation. The display device is further provided with an electro-optical layer (35) and means for activating said electro-optical layer (35). The display device is characterized in that the ionizable gas (33) contains a carrier gas and an additional gas, said additional gas comprising deuterium or deuterium hydrogen, or hydrogen and a further gas having a higher molecular weight. Preferably, helium or nitrogen is used as the carrier gas, and the additional gas comprises deuterium or deuterium hydrogen, or hydrogen and nitrogen, or hydrogen and xenon.

Abstract: Reference current loop comprising a group of identical ICs (1, 2, 3), comprising each a first impedance (7) connected in series to the first impedance of another IC of the group. The combination of first impedances is connected to a reference current source (4). The voltage across the first impedance (7) is convened to a current (I0) by a voltage-to-current converter (8) and made available as a current (I1, I2) proportional to the reference current (Iref) of the reference current source (4) by a current mirror circuit (20, 23). The relation between the currents I1 and I2 and the reference current Iref is determined by the ratio of the impedance value of the first impedance (7) to that of the second impedance (19). This ratio is the same for all the ICs, so that the currents I1 and I2 in all the ICs are mutually equal.
