Abstract: A run-flat tire capable of reducing weight and enhancing its uniformity. The run-flat tire 1 provides a troidal carcass 6 extending from a tread portion 2 to the bead core of each bead portion 4 through each of sidewall portions 3 and a pair of side reinforcing rubbers 9 arranged inside the carcass 6 and extending along the sidewall portions 3 in the tire radial direction inwardly and outwardly. In the outer surface of the tread portion 2, pattern elements are arranged, thereby forming a pitch pattern. Each of the side reinforcing rubber 9 provides with recesses 11 circumferentially spaced on the inner surface of side reinforcing rubber facing the tire cavity.

Abstract: The present invention is to provide a printing apparatus capable of correctly detecting an origin of a conveying roller for conveying a print medium at the time of its rotation with a simple configuration that does not accompany an increase of cost. For this purpose, the printing apparatus is equipped with a lock mechanism (a lock link lever) for stopping rotation of the conveying roller at a predetermined rotational position and saves a count value of a rotation amount of the conveying roller when the conveying roller is locked by the lock mechanism concerned as origin information. After this, driving of the conveying roller is controlled based on the saved origin information and a phase of rotation of the conveying roller obtained from the count value of the conveying roller.

The content transmitting unit (111) and the encapsulating unit (112) transmit plural content items by IP multicast. The content transmitting unit (111) adds, to a header of the content to be IP packetized, information concerning a condition of a receiving side node of the content.

Abstract: A recording apparatus includes guide rails that each control the posture of a carriage at an arbitrary recording position by being in contact with the carriage. The guide rails are disposed on respective sides of a guide shaft in a direction in which a recording medium is conveyed. The length of a gap between the recording medium and the carriage is selectable between a case where the carriage is in contact with one of the guide rails and a case where the carriage is in contact with the other guide rail. Such a configuration provides a compact and low-cost recording apparatus capable of performing recording on recording media having various thicknesses by appropriately adjusting the gap between the carriage and any of the recording medium while maintaining the parallelism therebetween.
