Abstract: To provide an electrode for an electricity storage device, which electrode employs a porous conductor having conductive nanostructures formed on its surface and makes it possible to provide a less expensive electricity storage device having a high discharge capacity and high charge/discharge cycle resistance. A porous conductor which is used as an electrode for an electricity storage device has a plurality of conductive nanostructures on a surface of the porous conductor.

Abstract: Provided is a mechanism allowing improvement of the degree of freedom in production when multiple users collaboratively produce a music track via a network. An information processing apparatus includes a control unit configured to receive multitrack data containing multiple pieces of track data generated by different users, edit the multitrack data, and transmit the edited multitrack data.

Abstract: A laser therapeutic device for a laser endoscope capable of relatively reducing the diameter of the endoscope while being capable of emitting a laser beam of a uniform intensity over a wide area is provided. An optical guide element (a square-shaped rod lens 15, a guide tube 2b) having a quadrangular cross section and guiding a therapeutic laser beam emitted from the tip of an optical fiber toward the tip side of a probe is used. On the tip side of a probe tube 2 being a barrel, using clearances C1 to C4 formed between the optical guide element and the inner circumferential surface of the probe tube, a camera unit 11 as imaging means and white-color LED units 12 and an ultraviolet LED unit 13 as illumination means are arranged.

Abstract: An apparatus includes a controller configured to generate a plurality of groups of content, control a display to display at least one content from each of at least two of the plurality of groups of content, and control the display to change display of the at least two of the plurality of groups of content based on a user command. Each group includes a plurality of content stored on a storage unit. The controller generates the plurality of groups based on information describing a selected content and information describing other content.

Abstract: Suction unit for an engine of horizontal single-cylinder direct injection type intended for producing a swirl in a suction air stream by means of a helical intake port, wherein, firstly, the intake port is formed to be "S"-shaped with its mid-section linear and prolonged for increasing the inertia force imparted to the suction air stream without increasing the width of the cylinder head and, secondly, the linear mid-section of the "S"-shaped intake port is formed to continue smoothly into an helical section so that the suction air stream enters unattenuated and guided by the helical passage to swirl up to approx. 180.degree. under acceleration before it enters a combustion chamber and the powerful swirl thus produced is further developed as it advances toward the center of the combustion chamber.
