    摘要： A method of compliance control of an industrial manipulator having a high position rigidity is achieved by integrating the motion equation to obtain a position displaced by a detected external force, calculating the trajectory of a position in a joint coordinate system with inverse kinematics, differentiating the calculated trajectory to obtain the trajectories of velocity and acceleration, and performing position control using these latter trajectories. The result is allowance of the compliance to be specified in any desired Cartesian coordinate system in the form of second-order perturbations including stiffness and damping. Moreover, the specified compliance can be realized with separation of the compliance specifications from the system feedback gain.

    摘要： A plurality of rectangular piezo-electric ultrasonic sector transducers are aligned to form an array, and each transducer has first and second electrodes on its radiating surface. The first electrode is located on a center line of the sector transducer's length, and has a first length in the longitudinal direction and a first width along the center line. Two of the second electrodes are arranged outside the first electrode, symmetrical to the center line. The two second electrodes have a second length in the longitudinal direction longer than the first length, and have a second width which is almost the same as the first width, along a line near the center line. Thus, diamond-shaped electrodes excellent for providing a beam narrow in the longitudinal direction can be employed as the first electrode, and the combination of the first and second electrodes can be connected to each other. The first electrode is designed to provide an ultrasonic beam narrow at a distance shorter than a focal length of an acoustic lens provided on the transducers, and the combination of the first and second electrodes is used to provide an ultrasonic beam narrow in another distance substantially longer than the focal length, so that a sharp beam can be delivered for both the short distance and the long distance.

    摘要： An optical reading device which is capable of being assembled readily and assures stabilization of the distance between a sensor of the reflecting type and a surface of a medium to be read by the sensor. The sensor is carried on a holding member, and an engaging member is pivotally supported on the holding member at a location spaced from the sensor. A screw shaft and a guide shaft extend in parallel to each other and to an axis of pivotal motion of the engaging member. The screw shaft has a spiral groove formed thereon for meshing engagement with a toothed portion formed on the engaging member or the holding member and is rotated to move the holding and engaging members therealong. A record medium to be read by the sensor is fed in a direction perpendicular to the screw shaft. A contact element is provided on the holding member for assuring a minimum distance between the sensor and a surface of the record medium to be read by the sensor. A resilient member is disposed between the holding and engaging members for urging them such that the contact element may be resiliently contacted with a sliding face and the toothed portion may be resiliently engaged with the spiral groove of the screw shaft.

    摘要： A compressor includes a plurality of pistons, a shaft and a wobble plate rotatably and swingably connected with said shaft so that the pistons are reciprocated in accordance with the wobbling movement of the wobble plate. The capacity of the compressor is varied in accordance with the inclining angle of the wobble plate. The actual capacity of the compressor is detected by the magnetic sensor. The compressor has a through member at the lower most portion of the pressure chamber provided in the housing and the slider is slidably connected with the through member. The slider also rotatably connected with the wobble plate so that the wobbling movement of the wobble plate makes the slider reciprocate along with the through member. Such movement of the slider is detected by the magnetic sensor.

    摘要： A semiconductor light-emitting device fabricated as a double hetero-structure InGaAsP/InP-type laser. The laser includes a buffer layer made of a semiconductor. The buffer layer is located at the upper edge of the flow region of electrons as seen from the active layer. The conductivity type of the buffer layer is opposite to that of a clad layer located at the upper edge of the flow region of electrons seen from the buffer layer. A, the band gap of the buffer layer is wider than that of the active layer but narrower than that of a clad layer adjacent to the buffer layer. The thickness of the buffer layer does not exceed the diffusion length of the electrons injected into the buffer layer.
