摘要： After cyclic original signals generated from a sensing element of an encoder are converted into digital signals, positions P(0) to P(n) in one period are obtained for each given period by means of a digital interpolator. If position data obtained immediately after a zero cross point is detected are P(0) and P(n) and if speed is fixed, an object should move on a straight line from a position P(0) to a position P(n). An actual detected position data P(m) is deviated from this straight line by D(m). This detection error D(m) and the detected position data P(m) are combined and stored in advance as reference data, and correction is carried out using the reference data every time position data is detected by the digital interpolator.

摘要： A capacitance-type encoder comprising a stator, a movable element, an excitation device and a signal processing device to obtain position data with low power-consumption. The stator has excitation-electrode sets electrically independent and displaced to have phase differences from each other to form a predetermined number of excitation-electrode groups. The movable element has connection electrodes having the same number as the excitation-electrode groups. The excitation device simultaneously applies a first pair of positive and negative pulse voltages respectively to two of the excitation-electrode sets having a phase difference of 180 degrees, and then simultaneously applies a second set of positive and negative pulse voltages respectively to the rest of the excitation-electrode sets. The signal processing device determines which one of four divided regions the movable element is positioned in based on a combination of detection signals when the first and second pairs of pulse voltages are applied respectively.

摘要： A driving control apparatus that can judge whether there is any abnormality in the operation of an acceleration sensor as well as in the mounting direction thereof. The driving control apparatus which controls the operation of a driven part via a driving device is constructed to include an abnormality judging circuit which, based on acceleration information from the acceleration sensor, judges the presence or absence of an abnormality in the operation of the acceleration sensor, or the mounting thereof with respect to the driven part, in addition to a position sensor or velocity sensor which detects the position or velocity of the driven part and the acceleration sensor which detects the acceleration of the driven part separately from the position sensor or velocity sensor. When judging information supplied from the abnormality judging circuit indicates the presence of an abnormality, the operation of the driven part is controlled, without using the acceleration information from the acceleration sensor, based on the position or velocity detected by the position sensor or velocity sensor.

摘要： An optical encoder includes a moving scale (1), a light source (2) which is always kept lighted, a fixed slit (3) and a light receiving array (4) having a plurality of light receiving units (41, 42). The light from the light source (2) is radiated toward the moving scale (1), thereby to generate signal light for a plurality of channels. The signal light for each channel passes through the opening (31; 32) of the fixed slit (3). The light passed through the opening (31) enters the light receiving unit (41), while the light passed through the opening (32) enters the light receiving unit (42). A plate-shaped light shield member (5) is interposed between the fixed slit (3) and the light receiving array (4) to optically separate the light passed through the opening (31) toward the light receiving unit (42) from the light passed through the opening (32) toward the light receiving unit (42) and thereby to prevent crosstalk between the channels.

摘要： An optical encoder with a high utilization efficiency of light and easy to manufacture. The optical encoder comprises a conversion device formed in such a manner that lens elements are arranged periodically with a reference pitch IP for converting a beam L emitted from a light source into a plurality of shifting beams MF. The beam L is contracted to a half of the reference pitch IP by the conversion device and goes out as a parallel beam, to impinge on a light receiving section. On a board of the light receiving section there are arranged light receiving elements with a pitch of IP/2. When an object connected to the conversion device is rotated or translated, the position of each lens element changes synchronously and the shifting beam MF scans an arrangement of the light receiving elements. As a result, a ratio of a light amount reaching the light receiving element changes periodically. The resultant electrical signal is processed by a well-known processing circuit.
