摘要： An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The controller is adapted to receive an indication of an increase in torque experienced at the atherectomy burr and is further adapted to, in response, regulate operation of the drive mechanism such that the increase in torque results in a noticeable reduction in speed of the drive mechanism such that a user of the atherectomy system notices the reduction in speed and is alerted to the increase in torque.

摘要： Driving of a pulse motor is controlled in such a manner that a rotating body driven by the pulse motor rotates at a uniform angular velocity. Angular displacement of the rotating body is detected, a difference between a detection value of the angular displacement and a target value of angular displacement set in advance is calculated, and a drive pulse frequency of a drive pulse signal to be used for driving the pulse motor is calculated based on the difference and a reference drive pulse frequency. Whether the difference is added to the reference drive pulse can be selected.

摘要： A control method for controlling the output of a controlled system in response to a control value including the steps ofmonitoring a controlled variable which is controlled by the controlled system, to find a monitor value which represents the controlled variable, andfinding a differential value representing the difference between the control value and the monitor value andwhen the differential value exceeds a specified upper limit value, replacing the differential value with the upper limit value, and when the differential value drops below a specified lower limit value, replacing the differential value with the lower limit value, thus finding a clipped value which is the differential value clipped by the upper limit value and the lower limit value, andsynthesizing the control value and the clipped value in such a way that the monitor value becomes negative feedback to the control value.

摘要： In a control device which includes an integrating positioning drive comprising a motor and transmission with backlash and lag, the backlash being the hysteresis of the transmission of mechanical quantities which occurs when the direction of rotation changes and which is caused, for example, by gear tolerances in the transmission due to manufacturng constrains, in addition to a first feedback path which supplies a signal proportional to the position of a control member, there is also provided a second feedback path developing a signal dependent on the positioning rate and the magnitude of the lag in the motor and, the mechanical members of the positioning drive are designed in such a manner that the transmission lag which occurs is greater than the sum of the position changes of the control member during starting of the positioning member over the period from stand-still to reaching its nominal speed and the position change occuring during the lag after the positioning motor is deenergized, providing a control device which can be used in applications which require high positioning rate as well as extremely small positioning steps.

摘要： In a nuclear reactor protection system, the control device initiates reactor shutdown when the amplitude of a voltage signal delivered by a detector oversteps a range limited by two adjustable values. The device comprises a stabilized supply, a detector supplied by a rectifier for delivering a d.c. voltage having an amplitude Ve which is proportional to the value of the signal to be measured, two generators for producing d.c. voltages of opposite sign having amplitudes Vd and Vref, and an adjustable voltage divider which delivers a periodic rectangular-wave voltage having an amplitude Vs. The detector output voltage is compared with the algebraic sum of the values Vd, Vref and Vs by means which produce a voltage level of 0 if the amplitude Ve is outside the range (Vd + Vref, Vd + Vref + Vs) and a voltage level of +1 if the amplitude Ve is within said range.

摘要： In apparatus and circuits especially suitable in instrumentation for indication and control of nuclear power plant coolant systems, a bridge contains in a sensing arm a resistance thermometer or a differential transformer. The output of the bridge is supplied to a servo amplifier which feeds a servo motor which is operatively connected to a bridge arm to utilize an error signal to rebalance the bridge and reduce the error signal to zero, and at the same time supply an input to a counting or indicating device. Unique circuits provide control set points, isolation being provided between the indication and control functions. New and improved phase sensitive monostable multivibrator transistor circuits are employed.

摘要： The control characteristics of potentiometers driven by the input and output shafts are compared and imbalance therebetween utilized to drive the output shaft motor in a direction to restore the balance. To avoid ambiguity in operation the potentiometers have an effective control characteristic range extending beyond 360* of shaft rotation to provide an overlap between the beginning and end of their ranges, which overlap is at least as great as the operational angular lag between the shafts. Means are provided for switching both potentiometers simultaneously from near the end of their ranges back to near the beginning of their ranges with such switchover occurring in the area of the overlap.
