    摘要： A decision feedback equalizer capable of coping with a high transmission rate and operable at a rate which is not effected by the number of taps. A first and a second shift register are respectively connected between a first and a second adder and between the second and a third adder. The output of a decision unit associated with the last tap is delayed one bit by a third shift register and then applied to multipliers at the same time. The multipliers, each being associated with respective tap, multiply their inputs by a first to a third tap coefficient, respectively. The resulting outputs of the multipliers are applied to the associated adders. The adders each has only to perform a single addition within a period of time corresponding to one bit.

    摘要： A sensing unit is constructed of a heater element and a temperature sensing element. The sensing unit is arranged in a region, in which measurement air, which flows into the inflow passage through the bypass inlet, bends at the substantially right-angle and contracts in flow. Alternatively, the sensing unit is arranged in a region immediately after an area, in which the measurement air flowing through the bypass inlet bends at the substantially right-angle. The lengthwise directions of the heater element and the temperature sensing element are respectively arranged to be in parallel with both thickness-wise side faces of the measurement body. Thereby, even when a flow rate of measurement air changes, an influence due to the change can be restricted from being exerted. Therefore, the maximum flow rate can be measured within the lengthwise range of the heater element from a low flow rate to a high flow rate.

    摘要： An airflow meter has a bypass passage disposed in an air passage and a sensing portion disposed in the bypass passage to detect an airflow amount. The bypass passage is provided with a restriction portion to gradually decrease a passage width of the bypass passage in an airflow direction in the bypass passage. The restriction portion includes a first restriction portion and the second restriction portion disposed at an immediately downstream side of a narrowest portion of the first restriction portion. The first restriction portion gradually decreases the passage width in the airflow direction. The second restriction portion increases the passage width than the passage width at the narrowest portion in a stepped manner. The sensing portion is located in a bound in which the restriction portion is disposed.

    摘要： An object of the present invention is to provide a novel stator structure in an electrical rotating machine which has a stator to one end of which an end plate provided with a bearing is fixedly mounted and a rotor rotatably supported by the bearing, in which unwanted metal particles produced during welding of the end plate to the stator are prevented from entering between the stator and the rotor. Positioning protrusions 61 are formed extending axially from the one end of the stator and positioning apertures 71 are provided in the end plate 65 for corresponding to and engaging with the positioning protrusions 61. Also, welding projections to be melted by resistance welding are arranged as located substantially on straight lines respectively extending from the rotation shaft 67 across the positioning protrusions 61 and on the outer side of the positioning protrusions 61. The end plate 65 is joined to the one end of the stator by welding at welding points 14. Unwanted metal particles produced during the resistance welding are blocked by the positioning protrusions 61 and will hardly flow towards the rotor 63.

    摘要： A lubricant (L) is stored in a lubricant reservoir (2c) of a casing (2). One end of a lubricant takeout pipe (15) is in communication with the lubricant reservoir (2c) and the other end thereof is in communication with a suction chamber (14) of a scroll mechanism (3). An inlet end of the lubricant takeout pipe (15) opens at the same level as an oil-level high-limit point of the lubricant reservoir (2c) in the vicinity of a lower end of a rotor (9b). When the level of the lubricant (L) moves up to the high-limit point, an excess lubricant is introduced from the lubricant reservoir (2c) into the scroll mechanism (3), since there is produced a difference in pressure between a lower space (2b) of the casing (2) and the suction chamber (14). As a result, the level of the lubricant (L) drops.

    摘要： 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 trasversal 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 trasversal 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 otehr 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.
