The rotary encoder comprises a substrate having a surface disposed opposite to the rotary body and at least one magnetoresistive element formed on the surface of the substrate. The magnetoresistive element is formed on the substrate surface as an integral pattern including at least two portions extending substantially in the radial direction of the rotary body in a relation opposite to the magnetic information recorded portion of the rotary body, two lead connection terminal portions formed at the outer ends of the radially extending portions respectively, and a circumferentially extending portion interconnecting the radially extending portions at their ends, so as to form a single electrical signal path which passes both of the radially extending portions and terminates in the two lead connection terminal portions. These lead connection terminal portions are disposed outside of the outer peripheral edge of the rotary body.

摘要： An endless counting apparatus comprises a first memory for storing a code of a first predetermined number of bits sufficient to represent the maximum value of each coded input expressed according to the binary notation, a second memory for storing an endless-making code of a second predetermined number of bits of higher order than and contiguous to the less and least significant bits stored in the first memory, and a control circuit for adding or subtracting the value of the coded input to or from the contents of the first and second memories depending on the input value to be counted and applying the result of addition or subtraction to the first and second memories. A method for endless counting by such an apparatus comprises clearing the most significant bit of the endless making code stored in the second memory when the code stored in the second memory has attained a value which causes an overflow due to a carry from the contents of the first memory if the carry occurs, and setting the most significant bit of the endless-making code stored in the second memory when the code stored in the second memory has attained a value which causes an underflow due to a borrow from the contents of the first memory if the borrow occurs.

摘要： The invention discloses a movement detecting device for detecting the movement state of a moving body such as a rotating body, in which a magnetic recording medium on which N and S magnetic poles are alternately recorded at a constant interval is fixed symmetrically with respect to a rotary shaft of a rotating body whose rotation state is to be detected, and an MR element comprising magnet-resistive elements is mounted at a fixed position relative to the magnetic recording medium so that the rotation state of the rotating body can be detected from variation of the values of resistance of the magnet-resistive elements caused by the rotation of the body. N and S poles are recorded on the magnetic recording medium with a small pole pitch P. The magnet-resistive elements are formed to have a width sufficiently smaller than the pole pitch. The magnet-resistive elements constitute a first group and a second group, the magnet-resistive elements of each group being disposed with an interval equal to the pole pitch or half the pole pitch. The magnet-resistive elements are disposed in such a manner that the interval between the groups is deviated from the pole pitch, whereby a circuit comprising these magnet-resistive elements can detect the rotation of the rotating body.

摘要： An encoder with a position detecting device is disclosed which is applicable to a brushless motor or the like, and includes a rotating body provided on a surface thereof with a magnetic material and magnetoresistive elements disposed opposite to and in close proximity to said magnetic material. The rotating body is provided with an encoding track in which a magnetic signal has been recorded in a predetermined direction of magnetization, and a position detecting track in which a magnetic signal has been recorded in a direction of magnetization intersecting with the predetermined direction of magnetization. The magnetoresistive elements are formed on an insulating substrate and face the tracks. Further, the magnetoresistive elements are arranged side by side in a radial direction of the rotating body and each of the magnetoresistive elements is placed so that the magnetoresistive element intersects the direction of magnetization in a track facing the magnetoresistive element, to make small the magnetoresistive element supporting substrate, thereby making the whole of the encoder small in size, and to prevent magnetic interference between the encoding track and position detecting track, thereby enhancing the performance of the encoder with the position detecting device.

摘要： A motor speed control method and system allow the motor to be accelerated to the steady state in the minimum time even under conditions of varying load torque, varying load inertia and varying power voltage. The motor is controlled by a voltage including a component of proportional term which is a function of a difference between a command speed and a detected speed, and a component of integral term which is summed during an acceleration phase. The acceleration of the motor during the starting process is measured and the integral term is modified basing on the result. The integral term may be memorized so that it is used as the integral term when the subsequent starting phase is completed. The integral term may be obtained from the acceleration and deceleration in the starting process.

摘要： A control process and apparatus for positioning an electric motor provided with a rotation angle detector at a designated position positively at a high speed without being accompanied with hunting notwithstanding variation in the motor current and inertia of a load. The control process activated upon starting of the motor and ending at the stoppage of the motor at the designated position includes a first control region in which acceleration of the motor having been started is detected and subsequently a constant speed operation of the motor is effected at a maximum speed. A deceleration initiating time point is determined in dependence on the acceleration. A second control region is provided in which the motor is decelerated in accordance with a deceleration pattern determined in dependence on a rotation angle extending between a position corresponding to the deceleration initiating time point and the commanded stop position, and motor torque and inertia of load is detected at the deceleration initiating time point. During a third control region the motor is progressively decelerated by reducing correspondingly the gain of voltage (current) applied to the motor when the motor position approaches to the commanded stop position. The control process also includes a fourth control region in which, when the motor stops short of or beyond the commanded position, the duty ratio of voltage applied to the motor is progressively increased to thereby re-start the motor toward the commanded position, and a fifth control region in which the motor is held at the commanded stop position.
