Abstract: A shoe sole that is less likely to feel push-up on the sole at the time of landing and suppresses pronation to enable quick weight movement in running or jogging, while being widely available in sports requiring weight movement such as golf, tennis, basketball, soccer, and skateboarding, as well as that is lightweight, has good wearing comfort and provides stable walking even in using on the street or walking. The shoe sole includes a shoe sole main body made of a flexible material, and a plate made of a material having a flexural modulus higher than a flexural modulus of the flexible material constituting the shoe sole main body, in which at least two of the plates are included in the shoe sole main body.

Abstract: An unmanned aerial vehicle according to the present disclosure is an unmanned aerial vehicle that can fly in midair and includes a propulsion unit configured to generate a propulsion force for fly in midair, a laser light source configured to illuminate laser light, an imaging unit configured to generate a captured image by capturing vertically below the unmanned aerial vehicle during flight in midair, and a controller configured to control an operation of the propulsion unit. The controller analyzes a captured image, extracts a light spot formed by laser light, measures a positional relationship with another unmanned aerial vehicle based on the extracted light spot, and executes a collision avoidance operation with respect to another unmanned aerial vehicle based on the measured positional relationship.

Abstract: A self-propelled robotic hand includes: a base capable of self-propulsion; an arm attached to the base; a hand attached to the arm for grasping an object; and a base securing unit attached to the base and configured to secure the base in place by electrostatic adhesion to a surface of a structure external to the self-propelled robotic hand.

Abstract: A robotic system includes: a detection unit that detects at least one of a voice, light and an image of a content outputted by a content output device; a decision unit that assesses information detected by the detection unit on the basis of reference data so as to assess the content outputted by the content output device; and a control unit that controls a behavior or a state of the robotic system on the basis of the assessment made by the decision unit.

Abstract: A user-friendly article identifying device capable of retaining voice data associated with a tag. The device contains a tag reading section; a voice data input section; a storage section; a determining section; a voice data replay section; and a controller for governing all the sections above. First, the tag reading section reads a tag having a specific identifier, and then the voice data input section accepts voice data. Storage section, which contains a voice data table, a tag/address table, and a memo data table, stores voice data from the input section so as to associate with the specific identifier of a tag. The determining section judges whether the tag identifier read by tag reading section is retained in the storage section. Voice data replay section replays the voice data associated with the identifier according to the judgment by the determining section.

Abstract: The present invention provides an ink reservoir which gives little reduction of print quality even after a prolonged use and is rigid and flexible enough to te packed into the ink cartridge with ease and maintains a good capacity of reserving an ink over an extended period of time because of an effective networking treatment achieved without heat compression. A novel ink reservoir made of polyurethane for use in printers is provided, prepared from as formulation at least one polyether polyol having an average hydroxyl value of from 30 to 200 mgKOH/g and a foam stabilizer having a surface tension of from 25 to 45 dyne/cm in the form of 1% aqueous solution.

Abstract: A beam spot controlling method for controlling the beam-converging position by a light beam from an objective lens on a recording track of a recording medium comprising the steps of (a) rotating a tapered prism having an inclination-imparting portion capable of imparting an inclination to a light beam which enters the tapered prism for changing the inclination of the light beam incident on said objective lens for controlling the beam-converging position by the light beam; (b) causing a light beam to enter the tapered prisms; and (c) causing the light beam exiting from the tapered prism to enter the objective lens, and directing the exiting light beam onto the recording track of said recording medium, and an apparatus for performing the above beam spot controlling method.
