Abstract: A method of and system for auctioning off commercial (CM) frame for on-air content and a method of and system for automatically sending on-air content. A broadcast station presents as an auctioneer a CM frame for sale and a lowest sale price to tenderers via a communication network. On the basis of the supplied information, each tenderer sends an auction application price for the CM frame to the auctioneer via the communication network. The auctioneer determines a successful tenderer for the CM frame on the basis of the highest auction application prices presented by the tenderers. The CM frame successfully tendered by this network auction is automatically registered in a broadcast sales information system along with CM content information to be incorporated in the CM frame. A content sending system takes the registered CM content from a CM bank at a predetermined broadcast time for automatic transmission and broadcasting.

Abstract: The present invention is intended to provide network delivery data transmitting methods and receiving methods which allow the selection of content data as desired by user. In a data transmitting system, a specification information packet for specifying a content source used, plural packet sequences each attached with identification information, and a correspondence information packet for relating the content sources with the identification information are multiplexed with on on-air stream, which is transmitted to each receiving system via a network. On the basis of the received specification information packet and correspondence information packet, each receiving system selects desired content data from plural pieces of content to view the selected content data at the same time or in a switched manner.

Abstract: A semiconductor laser light source device and light source unit according to the present invention include a first plate-like member made of metal, to which a semiconductor laser array is joined along the end portion, a second plate-like member made of metal, in which an inlet opening portion, which introduces cooling fluid, and a cooling fluid draining channel, and a third plate-like member made of metal, which is formed along the area corresponding to the end portion and to which at least one cooling channel is provided through which cooling fluid flows in the longitudinal direction of the semiconductor laser array by communicating the cooling fluid introducing channel and the cooling fluid draining channel. Thus, the sectional area of the channel can be larger than that in the construction of the related art and the processing cost is reduced by comparison with the construction of the related art.

Abstract: An ozone producing apparatus including: an oxygen atom producing portion (6) for dissociating a supplied oxygen gas at a low pressure not more than atmospheric pressure so as to produce a first gas containing oxygen atoms; an ozone producing portion (a throat 3 and a diffuser 4) for mixing the first gas containing oxygen atoms supplied from the oxygen atom producing portion with a second gas containing oxygen, and allowing the first and second gases to react with each other for producing ozone; and a low pressure feeding (2, 9) means for reducing a pressure in the oxygen atom producing portion (6) at a specified low value not more than atmospheric pressure, and feeding the first gas to the ozone producing portion in a pressure reduction state.
