  • Publication number: 20190358529
    Abstract: An example game controller includes a spherical housing, a joystick, an operation section, and a transmitter. The joystick protrudes from a surface of the spherical housing. The operation section includes an operation surface. The operation surface is capable of being depressed and is integral with the surface of the spherical housing. The transmitter transmits, to outside, information regarding an operation on the joystick and information regarding an operation on the operation section. Thus, it is possible to provide a game controller that allows for various types of operations.

  • Publication number: 20190358530
    Abstract: An example game controller includes a housing, an operation section, a light-emitter, and a lightguide. The housing has an opening. At least a portion of the operation section is exposed through the opening. The light-emitter is inside the housing and configured to emit light. The lightguide includes a light-receiving surface configured to receive light generated from the light-emitter and a light-exiting surface configured to output light received via the light-receiving surface to outside the housing. The lightguide includes a surrounding portion and an extended portion. The surrounding portion has the light-exiting surface and surrounds a circumference of the operation section. The extended portion is extended from the surrounding portion and has the light-receiving surface at a tip portion thereof.

  • Publication number: 20180361231
    Abstract: A non-limiting example portable apparatus comprises a housing, and the housing includes an accommodation member and a lid. A coupling member is provided with a main body and two protruding portions formed on a side surface of the main body, and is rotatably secured to the housing within a plane parallel to a rear surface of the housing (lid). Moreover, a ring-like member is formed of material capable of deforming more easily elastically than the housing and the coupling member, and has a shape that a part of a ring-like frame is cut out. Engaging portions are provided in end portions of the ring-like member, and the engaging portions are engaged with the protruding portions of the coupling member. Therefore, the ring-like member is joined to the coupling member rotatably in a direction that the ring-like member is tilted (opened) to the rear surface of the housing. A user holds or wears the portable apparatus by passing a finger through the ring-like member to use it.

  • Publication number: 20180275769
    Abstract: A non-limiting example cover includes a first cover portion that is provided with a plurality of operation buttons. Each of key tops of the plurality of operation buttons is constituted by a key top portion, an actuator and a conductive member. A connection portion of a conductive sheet is provided between the key top portion and the actuator, and the connection portion is connected, via a coupling portion, to a body portion that is provided on an outside of an area arranged with the key tops. The connection portion is connected to a protrusion provided on a lower side of the key top. Resin plating is applied to the protrusion, and when the key top is depressed and thus a portion of the key top portion where the protrusion is provided is brought into contact to the conductive member, the conductive member and the conductive sheet are electrically connected to each other via the resin plating.

  • Patent number: 9737423
    Abstract: A stent able to minimize occurrences of strain and stress concentration in a drug coat layer upon expansive deformation of the stent in a radial direction to avoid the possibility of the drug separating from the stent, includes a stent body and a drug coating layer coated on the outside surface of the stent body so that the thickness of the drug coating layer gradually decreases toward a bent portion of the stent.

  • Publication number: 20160235565
    Abstract: A manufacturing method of a stent is disclosed which prevents a drug from being peeled off or separated due to stress concentration or distortion resulting from the expanding deformation of the stent so that the drug is further uniformly effective and further improved yields are expected when the stent is manufactured, and a coating device. The method has a non-coating portion forming process of preventing a bending portion from being coated with the drug by causing a nozzle to go past the bending portion when the nozzle reaches the bending portion and to move toward main strut portions. In the non-coating portion forming process, an adhesion amount of a coating solution is reduced while the nozzle is going past the bending portion.

  • Publication number: 20160206451
    Abstract: A stent and a manufacturing method of a stent are disclosed in which a drug is satisfactorily and uniformly effective by preventing the drug from being peeled off or separated due to the stress concentration and/or the distortion resulting from the expanding deformation of the stent. The stent has an annular body configured to include a waved strut having a bending portion and multiple main strut portions. Then, only an outer surface of the main strut portions and a side surface of an end portion of the main strut portions adjacent to the bending portion are coated with the drug except the bending portion.

  • Patent number: 8523938
    Abstract: A stent includes a stent body in which struts are joined mutually while intersecting and which is formed tubularly as a whole, and a drug coat layer on the outer surface of the struts. The strut has a bend which is deformed as the stent body expands/contracts in the radial direction, and the drug coat layer with which the bend is coated is formed in such a manner that the drug coat layer is mountain-shaped in a cross-section perpendicular to the axis of the strut and the ridgeline of the mountain shape extends in a wavy shape along the longitudinal direction of the strut. The drug coat layer deforms relatively easily without using plasticizer as the stent deforms and is not so susceptible to causing problems such as peeling, destruction, damage or falling off of the drug coat later.
