  • Publication number: 20110304858
    Abstract: A movable body system includes a movable body to which an image pickup apparatus is attached; an image analyzer that performs image matching between the image captured by the image pickup apparatus and an image, which is previously captured on the travel path of the movable body; a wall-surface detector that detects directions of the movable body with respect to wall surfaces, which are arranged along the travel path, and distances between the wall surfaces and the movable body; and a traveling-direction calculator that detects a shift of the movable body with respect to the travel path from an output of the image analyzer or the wall-surface detector, and calculates a traveling direction to cause the movable body to travel on the travel path.

  • Patent number: 6822415
    Abstract: A electric motor control device is provided for controlling an electric motor which actuates a movable member of a machine through a transmitting mechanism. When a torque command is given as motion command signal (9) to servo device (3), servo device (3) sends input torque signal (12) corresponding to motion command signal (9) to electric motor (5), which is energized. Movable member (7) is thus moved, producing vibrations. Servo device (3) outputs input torque signal (11) equivalent to input torque signal (12), and input torque signal (11) and rotational speed signal (10) are stored in memory device (2). Analyzing device (1) analyzes the frequencies of input torque signal (11) and rotational speed signal (10) according to an FFT, and outputs analytical result (14).

  • Patent number: 5394248
    Abstract: A magnetic recording/reproducing apparatus for recording and reproducing a plurality of discrimination information corresponding to signal modes on a magnetic recording medium by utilizing a control signal. The plurality of discrimination information are indicated by discrimination information words which are determined by removing words, each of which is undistinguishable from the other words when being continuously arranged, from 2.sup.(2N-2) words each of which comprises 2N bits (N is a natural number equal to or more than 2) whose first bit is fixed to "L" or "S" and last bit is fixed to "S" or "L" and further by removing words which have an intermediate odd bit and the following even bit identical to the last bit and the first bit, respectively, from said 2.sup.(2N-2) words. This arrangement can record and reproduce both the discrimination information and VISS.multidot.VASS information and, in addition, can substantially record the back track prevention information.

  • Patent number: 4212471
    Abstract: A device for cutting sound grooves in a disc recording medium has a cutting stylus for recording sound by cutting on the disc recording medium. The cutting stylus comprises a cutting stylus structure of diamond having a cutting part for cutting the disc recording medium while producing a cut chip therefrom. A surface of the cutting stylus structure contacts the chip having been rendered electroconductive to a specific depth by an ion-implantation process.
