Abstract: A content delivery system includes a content management element for managing one or more of contents, a multicast delivery element for delivering a multicast stream of the content or contents, a unicast delivery element for delivering a unicast stream of the content or contents, and a terminal. In response to a delivery request, the content management element transmits to the terminal, first information identifying the multicast delivery element and second information identifying the unicast delivery element. The terminal receives and reproduces a multicast stream corresponding to desired content according to the first information. When special reproduction is requested, the terminal requests the unicast delivery element to perform the special reproduction according to the second information. In response to the request for special reproduction, the unicast delivery element delivers the unicast stream for the special reproduction to the terminal.

Abstract: An information input device which has portability for the sake of improved operation flexibility, and has high operational resolution as well. The information input device comprises: two plate-like input members capable of being slid against each other, being held between fingertips or part of two fingers of one hand; a holding part to be held with other fingers of the one hand; connecting parts for connecting the two plate-like input members to the holding part; and an information creating part for creating input information in accordance with a relative position or relative movement between the plate-like input members.

Abstract: The present invention forms a mixture basically consisting of threonine, proline, glycine, valine, isoleucine, leucine, tyrosine, phenylalanine, lysine, aspartic acid, serine, glutamic acid, alanine, methionine, histidine and arginine as a unit, by which a body temperature raising effect was observed. The similar body temperature raising effect was observed when carnitine and/or tryptophan is added to the unit. These groups were found to be amino acid mixture-containing agents capable of raising body temperature for food or drink use or medical use. The agents have excellent body temperature raising effect, thereby having the functions of reduction of accumulated body fat, alleviation of excess sensitivity to cold, warming of a cold body, and the like.
