  • Patent number: 9713426
    Abstract: The position of blood vessels can be more appropriately specified by means of appropriately selecting, on the basis of the conditions and components utilized, and angle between a light emitting unit optical axis of a near-infrared light emitting unit and a normal light of an irradiated surface, and angle between an optical axis of a light receiving side lens and the normal line of the irradiated surface, and an angle between a light receiving surface of a photo diode array and the light receiving unit optical axis. Thus, the subcutaneous blood vessel depth in the direction of the normal line from the irradiated surface can be specified based on changes in illumination intensity in a photodiode array. Consequently, the position of subcutaneous blood vessels can be easily specified.

  • Publication number: 20170190049
    Abstract: A control device of a robot for controlling the angle of a joint of the robot that is driven by a motor. The control device is equipped with: a joint angle command-calculating unit for calculating a joint angle command value; an axial force torque-calculating unit for calculating the axial force torque generated in the joint axis; an elastic deformation-compensating unit for calculating a motor command angle by adding a joint deflection, which is calculated from the axial force torque and a joint spring constant, to the joint angle command value; a stopping position-detecting unit for detecting the angle of the motor when the robot contacts an external structure; and a command angle-switching unit for outputting the motor angle detected by the stopping position-detecting unit instead of the joint angle command value when the stopping position-detecting unit outputs the angle of the motor.

  • Patent number: 9505074
    Abstract: A weaving control device of a multi-joint robot, which achieves high-precision weaving, and suppresses occurrence of weaving movement error stemming from the movement of another joint axis and the dynamic characteristics of the motor driving the joint axis. The weaving control device contains: a signal computation unit that computes the target position signal for each axis; a filter computation unit that computes a target command signal resulting from low-pass filter processing of the target position signal; and a motor control unit that drives each axis with the target command signal as an input. The frequency characteristics of the gain of the motor control unit are configured in an approximately flat manner, and the dynamic characteristics from the target position to the motor output angle are similar to the filter. A weaving signal correction unit computes a target position signal having a corrected gain on the basis of filter characteristics.

  • Patent number: 9272894
    Abstract: Easily serviced and hygienically maintained liquid supply system. A liquid storage vessel switching device switches between vessels to supply liquid uninterruptedly. Provided in a first connection tube is a liquid cutoff device, including a loop section, for switching the system between allowing/cutting-off supplying of liquid to a dispenser through the first connection tube. Utilizing the liquid cutoff device eliminates, along the first connection tube, intervening conventional valves having structural components that come in direct contact with the supplied liquid, and on which sponges or other cleaning elements might get caught. The inner wall of the first connection tube may thus be cleaned readily with a sponge or the like. Beverages such as beer thus can easily be kept hygienically and served.

  • Patent number: 9103451
    Abstract: A device for stopping a flow of fluid in a fixed length of tube with an actuator simple in construction is provided. The stopping device is free of direct touch with the fluid inside the tube, expected not to obstruct the flow in the tube as permitted as possible at normal condition, expected to perform both detection and control with a single device, and further invulnerable to kinds of fluids. The device for stopping a flow of fluid includes a tube holder to keep a tube in looped configuration, a movable part pressing the looped configuration of the tube. Pressing of the looped configuration of the tube make a snapped bent to stop the flow of fluid passed through the tube. Putting the movable part back into place results in the tube's returning from the configuration having the bent, allowing the fluid flowing again through the tube.

  • Patent number: 8955253
    Abstract: A detecting unit (14) forms a plurality of detection spots arranged two-dimensionally on a floor surface near a door panel (12). Each detection spot is capable of detecting a human or an object by infrared light independently from other detection spots. Region distinguishing means (30) distinguishes a region formed by plural ones of the said detection spots that have detected the human or object. Person's movement judging means (44) judges the direction in which the distinguished region moves. A signal which causes a door panel (12) to be opened is supplied to a door controller (34) only when the direction of movement of the distinguished region is the direction toward the door panel.
