Abstract: The invention relates to a welded part (1) made from plastic between the flexible walls of a container, in particular of a bag, with a stub (3) which is formed integrally on the welded part at the top and forms a pouring channel which connects the upper pouring opening of the stub to the lower pouring channel region (3a) of the lower welded region (2), wherein a barrier layer (6) is arranged in the pouring channel, which barrier layer (6) is opened by a projection (8) of a closure cap (7) which can be screwed onto the stub (3), wherein the projection (8) of the closure cap (7), which projection (8) reaches into the pouring channel (4), is fastened to the barrier layer (6), as a result of which the barrier layer (6) is removed completely or partially when the closure cap (7) is screwed open.

Abstract: The invention relates to an apparatus for applying for liquid agents, such as hair cosmetics and/or dyeing and/or bleaching liquids, to hair on the head by means of wicks which are arranged in parallel rows and, on account of their capillary action, obtain the liquid agent from a reservoir chamber, with the wicks forming the tines of a comb.

Abstract: A supply holding hair-treatment liquid has an elongated dispenser spout and is used with an applicator having a body fittable to the supply with the spout projecting a predetermined distance beyond the body. A plurality of hard support core pins are fixed on the body extend adjacent the spouts and respective soft cover sheaths fitted over the support pins form therewith teeth projecting from the body beyond an outer end of the spout when the body is fitted to the supply.

Abstract: In a circuit arrangement, in particular for a capacitive acceleration sensor having a first capacitor and a second capacitor, the two capacitors have a common middle electrode, which is movably supported in dependence upon an acting acceleration. A position-control circuit applies a voltage to the outer electrodes of the capacitors so as to keep the capacitors equal in size. An a.c. voltage is applied to the middle electrode and the a.c. current adjusting itself at the capacitors is evaluated for purposes of position control.

Abstract: A receiving comparator for a data-transmission system comprising at least one control unit and data-transmission lines, in particular for at least one Controller Area Network (CAN) controller and one CAN bus system having a CAN bus (CB) is proposed, which is distinguished by the feature that the individual circuit elements are monolithically integrated. By generating a switching threshold which is independent of the operating voltage and temperature with the aid of a current source (I.sub.S), one prevents the CAN bus potentials from being asymmetrically influenced. The arrangement guarantees a processing of digital signals with a high data rate, whereby the input common-mode range extends up to above the supply voltage and to below ground.

Abstract: A transmitter end stage for a data transmission system comprising at least one control unit and data transmission lines, especially for a CAN bus system having at least one CAN controller and one CAN bus (CB) is proposed, characterized by the fact that the individual circuit elements of transmitter end stage 18 are integrated monolithically. As a result of the special layout and its circuit-design arrangement of the individual elements (3, 5; R1, D1, T1; R2, D2, T2; D10, D20) of the transmitter end stage, the effects of malfunctions, for example of short circuits of the data lines to ground or to the supply voltages, are reduced to a minimum. As a result of the special choice of pre-drivers (3, 5), minimum delay times are achieved, so that signals can be transmitted at a higher data rate.

Abstract: A monolithically integrated circuit in the packed state has at least one characteristic value and/or at least one function which is able to be varied by applying at least one striking potential to at least two of the standard terminal connections leading to the outside of the integrated circuit.

Abstract: An integrated circuit having an adjusting component and an adjustable thyristor allows an especially small chip surface to be used. The integrated circuit has a control unit, by means of which the adjusting component is irreversibly switched. The thyristor is designed as a planar component.
