Abstract: A motor driving control device according to the present invention is one for controlling, for example, a motor (1) for driving an optical system (10) in a copying machine. An encoder (2) is connected to the axis of rotation of the motor (1), and a signal of the encoder (2) is applied to a control circuit (3). The control circuit (3) includes a microcomputer (4), a memory (5) and a driver (6). The microcomputer (4) calculates a rotational speed N and a rotational position ϑ of the motor (1) on the basis of pulses applied from the encoder (2). An acceleration A is stored in the memory (5). The microcomputer (4) calculates a command speed V = √ 2Aϑ ¯ on the basis of the acceleration A and the calculated rotational position ϑ, and applies the same to a driver (6). The driver (6) outputs a driving signal proportional to the difference between the rotational speed N of the motor and the command speed V. According to the present invention, when the motor (1) is decelerated or accelerated, the speed can be varied in a short time and smoothly.

Abstract: A control system especially but not exclusively for use downhole in a well bore during drill stem testing, includes first means (38) for producing a first response to a changing stimulus (eg. well bore pressure changing at a varying rate); second means (58) for producing a second response to the stimulus, which response is initially masked by the first response; and signal producing means (6) arranged to produce a signal when the second response exceeds the first response. In one embodiment, two components (38,58) are moved in different directions, but in a net first direction, until the rate of change of the pressure is sufficiently low (e.g. near steady state), at which time the rates of movement of the two components produce net movement in a second direction which initiates a control valve (6) to produce a signal.

Abstract: A foot pedal arrangement wherein a support structure is mounted to the front wall of a diesel powered truck cab. A spring biased spool (40) is mounted to the support structure and is interconnected to a potentiometer (60). A foot pedal (80) includes a projecting arm (72) that is pivoted to the support structure. A flexible link connection (90) between the foot pedal arm and the spool forces rotation of the spool with pivoting of the pedal. The connection is designed to translate the traditional pedal movement to the required spool rotation as needed for monitoring by the potentiometer.

Abstract: A continuously variable transmission on a motor vehicle is controlled by establishing a target acceleration Go to be reached according to an indication of the driver's intention for acceleration or deceleration, such as the amount of depression of the accelerator pedal, and also to an indication of the speed of the motor vehicle. A present calculative acceleration G CAL is calculated on the basis of a reserved power Pa of the engine which drives the continuously variable transmission. A target acceleration Gon required at the present time to vary the present acceleration up to the target acceleration Go to be reached along a desired characteristic curve is established according to the difference ΔG (= Go - G CAL ) between the target acceleration Go to be reached and the calculative acceleration G CAL . Then, the throttle valve of the engine on the motor vehicle and the continuously variable transmission are controlled so that the target acceleration Gon will be reached.
