Abstract: In a rotary connector where a moving body turning with the rotation and revolution of planetary gears and flat cables including inverted portions at middle portions thereof are received in a receiving space between outer and inner cylindrical bodies, a bottom plate of a stationary-side housing is provided with an annular protrusion that comes into contact with lower surfaces of the planetary gears and a hollow portion that is positioned outside the annular protrusion in a radial direction, and the hollow portion is positioned directly below in a vertical direction when the stationary-side housing is mounted on an installation portion of a vehicle. Accordingly, a foreign matter entering the receiving space falls down onto the bottom plate and is accumulated in the hollow portion. Therefore, the hindrance to the rotation of the planetary gears, when the planetary gears catch a foreign matter, can be prevented.

Abstract: This invention provides organic-inorganic hybrid particles containing as the essential components a block copolymer comprising an uncharged hydrophilic polymer chain segment and a polymer chain segment containing a repeated structural unit having a carboxylate ion group at its side chain; calcium ion (Ca2+), phosphate ion (PO43?) or carbonate ion (CO32?), or a mixture of these anions; and a contrast agent. The particles provide, in particular, carriers for stably delivering an MRI contrast agent to a target site.

Abstract: In a rotary connector in which a movable body rotating with rotation and revolution of a planetary gear and a flat cable having a reversed portion are housed within a housing space defined between outer and inner cylindrical bodies, restricting walls extending in the circumferential direction with an opening therebetween are erected on the movable body molded of resin, the reversed portion is passed through the opening, and the radial movement of the flat cable is restricted. A plurality of groove portions are formed in the inner peripheral surfaces of the restricting walls so as to be continuous with one another along the circumferential direction, and the depth d of the groove portions and the central angle ? corresponding to the length in the circumferential direction of the groove portions are set within ranges of 0.5 mm?d?2.0 mm and 5 degrees???30 degrees.

Abstract: There is provided a rib structure formed at a predetermined position inside a cabinet and at positions around a display panel housed in a cabinet, the rib structure including a first rib portion that is substantially linear and one end of which is opposed to a side face of the display panel and a second rib portion that is substantially U-shaped and connected to an other end of the first rib portion at a nearly bottom position of the U-shape and two ends of the U-shape being connected to a wall face of the cabinet.
