Abstract: A transmission system includes: an antenna; a control device including an RF circuit which transmits a first signal for controlling a radio wave to be outputted from the antenna and an external power supply which supplies direct current to the antenna; and a first transmission path which connects the antenna and the control device, and is used in transmission of the first signal and supplying of the direct current to the antenna.

Abstract: To provide a release film not to contaminate a mold or a molded article. The present invention provides a release film comprising, an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a first face of a base layer that is formed of a polyethylene terephthalate resin; a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer; and a surface layer formed of a fluororesin and laminated on a second face of the base layer, or an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a second face of the base layer, and a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer that is laminated on the second face.

Abstract: To provide a release film not to contaminate a mold or a molded article. The present invention provides a release film comprising a base layer formed of an easily moldable polyethylene terephthalate resin and surface layers laminated on two faces of the base layer and formed of a fluororesin. The present invention also provides a method of manufacturing a release film. The method comprises an applying step of applying a fluororesin composition onto two faces of a base layer formed of an easily moldable polyethylene terephthalate resin and, after the applying step, a curing step of curing the fluororesin composition. By molding with the release film, contamination of a mold or a molded article is prevented. The release film can be used in molding multiple times.
