  • Publication number: 20140230713
    Abstract: An underwater mobile inspection apparatus is capable of inspecting a subsea pipeline (inspection object) while cruising. The underwater mobile inspection apparatus includes: a cruising body configured to submerge under water and cruise along the inspection object in such a manner as not to come into contact with the subsea pipeline; a first movable arm provided on the cruising body; an inspection tool unit for use in inspecting the subsea pipeline, the inspection tool unit being provided on the first movable arm; and a controller configured to, when the cruising body cruises along the subsea pipeline in such a manner as not to come into contact with the subsea pipeline, operate the first movable arm to move the inspection tool unit, such that a positional relationship of the inspection tool unit with the subsea pipeline becomes a predetermined target positional relationship.

  • Publication number: 20130345866
    Abstract: A control system and teaching method for a seven-axis articulated robot are provided, which system and method are capable of easily grasping a motion trajectory of the whole robot and thereby performing proper teaching during teaching operation. The control system includes a setting device for setting a specified plane in a teaching mode for teaching a seven-axis articulated robot; a control unit for controlling the movement of the seven-axis articulated robot so as to restrict a motion trajectory of an elbow portion within the plane set by the setting device; and a computing unit for performing inverse transform operation to calculate the pivot angle of each pivot axis based on a change in a position of the hand end, setting the restriction of the movement of the elbow portion as a constraint condition, when the position for the hand end is taught.

  • Publication number: 20130310973
    Abstract: Provided is a method of controlling a seven-axis articulated robot including seven joints sequentially arranged from a proximal end of the robot to a distal end of the robot, the seven joints including rotational axes each causing a next joint to turn and rotational axes each causing a next joint to pivot, such that the rotational axes causing turning and the rotational axes causing pivoting are arranged alternately, the seven-axis articulated robot being configured such that rotational axes of three proximal end side joints of the robot do not intersect with each other at one point. The method includes performing inverse transformation using, as a constraint condition, such a joint angle of a middle joint among the three joints as to cause an assumed elbow angle to be constant in a case where a rotational axis of the middle joint is assumed as a shoulder.

  • Publication number: 20120258988
    Abstract: A therapeutic or prophylactic agent for diabetes includes a thiazolidine derivative as a PPAR-? agonist as an effective component which exhibits a reduced side effect of the PPAR-? agonist. The therapeutic or prophylactic agent for diabetes includes a particular IP agonist such as beraprost sodium (BPS), and a thiazolidine derivative such as pioglitazone or a pharmaceutically acceptable salt thereof. Since the therapeutic or prophylactic agent exhibits a sufficiently effective hypoglycemic action without being accompanied by side effects characteristic to PPAR-? agonists, the agent is useful as a highly safe and effective therapeutic or prophylactic agent for diabetes.

  • Patent number: 7925382
    Abstract: An input unit enters angular displacements by which drive shafts of a robot arm are to be turned as teaching data into a control unit. The control unit converts the input angular displacements into position-attitude data, namely, converted commands, indicating a position of the free end of the robot arm and an attitude of the robot in a rectangular coordinate system through forward conversion. The control unit corrects the position-attitude data on the basis of inherent errors in the robot to provide corrected position-attitude data. The control unit converts the corrected position-attitude data into corrected angular displacements through inverse conversion and gives the corrected angular displacements to an actuator included in the robot. The inherent errors in the robot include mechanismic errors resulting from machining errors and assembling errors, installation errors and errors in the origins of axes.

  • Patent number: 7235947
    Abstract: A desired q-axis current is determined based on a desired torque, and a desired d-axis current is determined based on the rotating speed of a synchronous motor when the terminal voltage of the synchronous motor coincides with a predetermined maximum permissible voltage to weaken a magnetic field created by the synchronous motor equivalently and to prevent the drop of the output torque of the synchronous motor. The desired d-axis current is determined based on the desired torque and the rotating speed. Therefore, the desired d-axis current can be reduced when a high torque is not necessary and undesired increase of the desired d-axis current can be prevented. Thus the synchronous motor operates efficiently, heat generation of the synchronous motor is prevented and power factor is improved.

  • Patent number: 6657156
    Abstract: A weld portion detector (20) and a laser beam projector (10) disposed a predetermined distance behind the weld portion detector (20) are moved together. The weld portion detector (20) detects a weld line and the laser beam projector (10) projects on the weld line detected by the weld portion detector (20) for laser welding. Pieces of data on weld positions sequentially detected by the weld portion detector (20) are stored sequentially in combination with times when the pieces of data on the weld positions are obtained and moving speeds of the weld portion detector (20) in a memory. A time when the weld portion detector (20) passed a point at which the laser beam projector (10) has just arrived is calculated on the basis of the times and the moving speeds stored in the memory. The laser beam projector (10) projects a laser beam on a weld position detected at the thus calculated time.
