  • Publication number: 20190301917
    Abstract: First to eighth laser measurement sections (30a) to (30h) of a laser measurement unit (30) measures a height of a surface of powder resins (15) in a coil insertion range CA for every angular degree in a circumferential direction of a stator core (2). A control unit (18) computes the number of points where the height of the surface is lower than a predetermined height among measurement results at multiple points measured by the first to eighth laser measurement sections (30a) to (30h), where the number of points is defined as an index value indicative of a dispersion of the measurement results. When it has been determined that the index value exceeds a first predetermined value, a notification is issued by outputting from a speaker (32) a sound indicative of the fact that the index value that has been computed exceeds the first predetermined value.

  • Publication number: 20180176524
    Abstract: The laser projection display device includes a scanning mirror reflecting and two-dimensionally scanning a laser beam emitted from a laser light source and sensors detecting rotation angles of the scanning mirror, and controls driving of the scanning mirror on the basis of sensor signals output from the sensors. At this time, a temperature compensation unit compensates for temperature dependency of a transfer characteristic of a signal transmission line for transmitting the sensor signals according to a temperature measured by a thermometer arranged in the vicinity of the scanning mirror. In order to correct amplitudes and phases of the rotation angles of the scanning mirror obtained from the sensor signal, the temperature compensation unit includes a look-up table storing correction amounts for each temperature.

  • Patent number: 7995429
    Abstract: There are provided an optical disk device and tilt correction processing method for performing recording/reproduction by rapidly acquiring an optimal tilt correction value for an optical disk having a plurality of recording/reproducing layers. In an optical disk device capable of recording or reproducing information by irradiating a laser beam to each of a plurality of recording/reproducing layers of an optical disk, the tilt value is stepwise set within a predetermined range at a predetermined radius position of the recording/reproducing layer located at the farthest distance from the laser beam irradiation side so that an optimal tilt correction value can be obtained from the quadratic function by the method of least squares of the jitter or the like obtained from the disk. By applying the optimal tilt value obtained to the other recording/reproducing layer, it is possible to start recording or reproduction in a short time.
