Abstract: A tire equipped with a sensor patch includes a sensor module and a sensor patch. The sensor patch is formed integrally with the inner liner of the tire by being vulcanized into the inner circumferential surface, and an accommodation space is formed in a region so that the sensor module can be fixed therein. A sensor patch is integrated with the inner liner without damaging the inner liner, and thus the sensor patch can be strongly bound to the tire. Furthermore, since the sensor patch is formed to have a thickness smaller than the thickness of the inner liner, when the sensor patch is vulcanized into the inner liner, the pressure of the bladder being exerted locally non-uniformly on the inner liner can be prevented.

Abstract: Layers of build and support material on an intermediate transfer surface are exposed to a solvent using a solvent application station to make the build material tacky, without affecting the support material. Then, the intermediate transfer surface moves past a transfuse station (the transfuse station is positioned to receive the layers after exposure to the solvent) and a platen moves relative to the intermediate transfer surface to contact the platen to one of the layers on the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build material and the support material to the platen each time the platen contacts the layers on the intermediate transfer surface at the transfuse station to successively form a freestanding stack of the layers of build and support material on the platen.

Abstract: A warm-air blowing circuit and another warm-air blowing circuit are disposed so as to heat a film from both sides of a projection side and a recess side of a die, warm air reaches and heats the film from the time of supplying of the film, warm air continues to enter a space in which a resin is to be ejected even after the die is closed, and thereby the film is likely to extend. Therefore, the film is unlikely to be torn at the time of molding when the film is likely to be shaped after a shape of the die and it is possible to prevent broken pieces of the film or broken pieces of a decoration film from being mixed and being stuck to the surface of the die such that it is possible to improve quality of the external appearance of a molded product.
