Patent EP-0366083-A2 (EP)
Inventor: TANAKA MASAHIRO
IPC: H03K17/082
Filed: 1989-10-24
Abstract: An integrated circuit includes an output circuit (10), a conducting circuit (11), a trigger voltage generator (12) and a connecting circuit (13). The output circuit has an input terminal (I) and an output terminal (X) and sets the output terminal to a high potential (Vcc) corresponding to logic "1" when the potential applied to the input terminal corresponds to logic "0". On the other hand, when the potential applied to the input terminal corresponds to logic "1", the output circuit sets the output terminal to a low potential (GND) corresponding to logic "0". The conducting circuit conducts and passes a current from the output terminal when the potential of the output terminal becomes equal to a predetermined potential higher than the high potential. The trigger voltage generator generates a trigger voltage (V T ) proportional to the current passing through the conducting circuit when it conducts. The connecting circuit sets the potential of the input terminal of the output circuit to the low level corresponding to logic "0" when the trigger voltage is applied to the connecting circuit.

Abstract: An aerosol delivery article provides volatilized flavor or drug by heating a flavor or drug carrying substrate, but not burning any material. A heat source which includes a metal oxide (eg., calcium oxide), an anhydrous metal sulfate (eg., magnesium sulfate), an inorganic salt and a sugar, generates heat upon contact of water therewith. The heat produced by the heat source heats flavor or drug which is in a heat exchange relationship therewith. The flavor or drug is volatilized and is drawn into the mouth of the user of the article. Typical heat sources heat the flavor or drug to a temperature within 70°C to 200°C for 4 to 8 minutes.

Abstract: In a method for constructing a ballastless superstructure in which a continuous concrete slab is applied to the formation, the track panel (rails with sleepers) is supported on the concrete slab, the track panel is adjusted if appropriate, and concrete is cast into the gap between the sleepers, above the concrete slab and between laterally raised limitations, it is proposed that the concrete slab is made integral with laterally raised concrete edge-beams which can be travelled over after hardening. Thus, lateral shuttering is dispensed with; automatic concrete finishers can also be used for filling the gaps between the sleepers.

Abstract: In a parallel-mode adaptive transversal equalizer, P- and Q-channel data streams from A/D converters (1, 5) are respectively passed through the tapped-delay lines of transversal filters (2, 6), on the one hand, and are one-symbol delayed, on the other, by delay circuits (3, 7, 66, 67) to produce (N-1) successively delayed P- and Q-channel data streams, which are respectively passed through the tapped delay lines of transversal filters (4; 63, 8; 64). In each transversal filter, symbols appearing at successive taps of the tapped-delay line are sampled and held for a duration of N symbols to produce first and second groups of stored symbols, the stored symbols of the first group being multiplied by first tap weights and summed, producing N first equalized outputs for each channel. The stored symbols of the second are multiplied by second tap weights and summed, producing N second equalized outputs for each channel. The first equalized outputs of each channel are respectively combined by adders (10-14, 68, 69) with the second equalized outputs of the other channel and multiplexed (14, 15) into P- and Q-channel outputs. Correlations are detected by correlators (16-19, 70, 72) between data and error components of each of the P- and Q-­channel outputs to control the first variable tap weights of associated tapped-delay lines, and correlations are detected by correlators (20-23, 71, 73) between data components of one of the P- and Q-channel outputs and error components of the other channel output to control the second variable tap weights of associated tapped-delay lines.

Abstract: An apparatus and method for determining the location of a pipe leak detects the pipe leak sound at a first remote location and at a second remote location, and generates first and second signals indicative of the sound. A time lag between the first and second signals is calculated at each of a plurality of frequencies. Integer multiples of an associated period are added to each time lag to form a plurality of potential time delays at each of the plurality of frequencies. The plurality of potential time delays at all of the plurality of frequencies are stored in a memory. The time delay value which occurs most frequently is selected from the memory and is utilized to calculate the location of the sound source relative to the first and second locations. The invention can also be employed to determine the location of a sound source other than a pipe leak.
