Granted: 2023-07-10
Abstract: The present invention discloses a stabilizer circuit with a frequency compensation circuit adapting to load changes, comprising: a first-stage amplification circuit, a second-stage amplification circuit, an output-stage circuit, and a frequency compensation circuit adapting to load changes, a frequency compensation circuit adapting to load changes, comprises a compensation capacitor C1, a sixth MOS tube M6, a seventh MOS tube M7, an eighth MOS tube M8, and a ninth MOS tube M9, wherein an output terminal of the first-stage amplification circuit is connected to an input terminal of a second-stage circuit, an output terminal of the second-stage circuit is connected to the output-stage circuit, and the frequency compensation circuit adapting to load changes is connected between a second-stage input terminal and a second-stage output terminal. Advantages: Compared with a circuit in which a fixed resistance is used as pole-zero point compensation, the circuit in the present invention uses a MOS tube as an adjustable resistance, and a proper adjustment relationship is created between the circuit and the load current, so that the circuit can automatically adjust the pole-zero point frequency when the load current changes. Therefore, the system can operate stably in different load current conditions, and the premise for a larger current is provided.

Abstract: The invention relates to a method for determining characteristics of the flow of a medium in a channel by measuring the transit time of sound waves which are transmitted between one or more transducers, and determining the characteristics from the measured transit times. In one embodiment of the method according to the invention, at least two sound waves whose transit time depends on swirl are transmitted along acoustic paths with a different sensitivity to swirl, and a measure of the swirl is determined from the measured transit times. In another embodiment, at least two sound waves whose transit time depends on the symmetry of the flow profile are transmitted along acoustic paths with a different sensitivity to symmetry, and a measure of the symmetry is determined from the measured transit times. These embodiments are preferably combined. If weighting factors are allocated to the values obtained, the individual velocities of the sound waves can be used to calculate the average flow velocity and/or the throughput of the medium. Since allowance is made for possible disturbances of the velocity profile, the accuracy of the calculated variables is good. The invention also provides for a device, by means of which the method according to the invention can be carried out. <IMAGE>

Abstract: An on-machine-seamable papermakers' fabric includes a first and a second base fabric, each of which is joined into endless form with a seam. The first and second base fabrics are attached to one another by at least one layer of staple fiber batt entangled therethrough such that they are offset with respect to one another in a lengthwise direction when so joined. As a consequence, seaming loops at one widthwise edge of the first base fabric coincide with a non-seam region of the second base fabric, and seaming loops at one widthwise edge of the second base fabric coincide with a non-seam region of the first base fabric. These coincident non-seam regions have additional flow-resistant material included so that when the on-machine-seamable papermakers' fabric is joined into endless form by closing both seams, it may, in the vicinities of the seams, have permeabilities to air and water substantially identical to the remainder of the fabric body thereof. Alternatively, the on-machine-seamable papermakers' fabric includes a multi-layered integrally woven base fabric having two systems of machine-direction yarns forming seaming loops in two distinct rows separated from one another in a thicknesswise direction of the fabric along each of its two widthwise edges. The two distinct rows are offset with respect to one another in a lengthwise direction of the base fabric. As a consequence, the seaming loops in one row coincide with a non-seam region of the base fabric at each widthwise edge thereof. The coincident non-seam regions, as above, have additional flow-resistant material. <IMAGE>
