  • Patent number: 10108200
    Abstract: In an autonomous traveling apparatus, a normal traveling area and a deceleration area are set for a monitoring area in an area setting unit. A speed control unit limits a traveling speed of an apparatus main body on the basis of the monitoring area set in the area setting unit and a distance from the apparatus main body to an obstacle within the monitoring area if the obstacle present within the monitoring area is detected. If the obstacle is a movable body, an area change unit changes the deceleration area within the monitoring area that is set in the area setting unit to a deceleration area for movable body. This configuration makes it possible to support even a case where an obstacle is a movable body, in limiting the traveling speed in response to obstacle detection.

  • Patent number: 8599669
    Abstract: Recording mark forming method utilizing a device including a laser and a laser drive carried by a pickup having a movement drive wherein a control controls the drives to irradiate a recording medium with laser pulse sequences to form recording marks having recording mark lengths between a predetermined and maximum lengths, a top section, a last section including a cooling period, and an intermediate period. Heat of mark front edges is controlled by top section recording parameters classified according to recording mark lengths and recording parameters of first through maximum recording mark lengths are classified into a same group. Heat of mark rear edges is controlled by cooling start positions for cooling periods classified according to recording mark lengths. Cooling start positions for a second predetermined mark length through the maximum mark length are classified into a same group. The second mark length is longer than the first mark length.

  • Patent number: 8503278
    Abstract: A recording parameter setting device setting parameters of pulse sequences forming recording marks on recording media. The device includes a storage section storing first and second look-up tables, and a recording parameter setting section for obtaining from the tables and setting parameters corresponding to recording information. The pulse sequences form at least marks equal to or longer than a first predetermined length but not longer than a maximum mark length, and include top and last sections. Also, the first lookup table stores parameters for top sections that control heat of front edges of marks classified into a same group. The second lookup table stores parameters for last sections for controlling heat of rear edges that are equal to or longer than a second predetermined recording mark length, that is longer than the first predetermined recording mark length, through the maximum recording mark length and classified into a same group.

  • Patent number: 8189442
    Abstract: A recording parameter setting device includes a trial recording parameter setting section and a reproduced signal quality judging section. The trial recording parameter setting section sets a trial recording parameter capable of controlling a heat level at least rear edges of recording marks, classified in accordance with recording mark lengths, and grouping a predetermined recording mark length or longer into a same group. The reproduced signal quality judging section judges whether a trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If the signal quality is unsatisfactory, the trial recording parameters of the predetermined recording mark length or longer are regrouped and trial recording is carried out again until the reproduced signal satisfies the predetermined signal quality. Then, the reproduced signal quality judging section sets the trial recording parameter as the recording parameter.
