Abstract: Provided are a tire vulcanization device and a tire vulcanization method. A container ring is disposed on an outer circumferential side of segments mounted on outer circumferential surfaces of sector molds. A bolster plate is disposed above an upper plate mounted on an upper surface of an upper side mold. A green tire is placed in a sideways state on a lower side mold mounted on an upper surface of a lower plate. In a state where the bolster plate is moved downward by a pressurizing mechanism and maintained in a mold closed position, a container ring held slidably in a vertical direction with respect to the bolster plate by a connecting body is moved downward by pressurizing fluid supplied, and the sector molds are assembled in an annular shape to be closed with the upper side mold pressed against upper surfaces of the sector molds.

Abstract: Provided are a method for producing a tire vulcanization mold and a maintenance method. A positioning member protrudes at a position corresponding to a position on a master mold surface. A positioning hole is formed by a tip end of the positioning member in a rubber mold to which the surface of the master mold is transferred. The tip end is embedded in the positioning hole so that a rear end protrudes from the surface of the rubber mold. The rear end is embedded in a plaster mold to which the surface of the rubber mold is transferred. A case is detachably fixed to the tip end protruding from the surface of the plaster mold. The case is cast into a mold to which the surface of the plaster mold is transferred and fixed. A valve body is inserted into the case from which the positioning member is removed.

Abstract: Provided are a method and a device for attaching a sound absorbing member to an inner face of a tire. In a state that an adhesive is interposed between a first face of a sound absorbing member and an inner face of the tire, the sound absorbing member is placed, and an expandable and contractible bag placed inside the tire is expanded, and the expanded bag presses a second face of the sound absorbing member to bond the first face to the inner face of the tire with the adhesive therebetween.

Abstract: In a tire vulcanization device and method, when a mold is closed, dividing walls disposed on an outer circumferential side of a container ring form a space with a container and hermetically block communication between the inside and outside of the container, and a center vent path communicating vertically through a center mechanism, a plurality of mold interior vent paths formed in the mold at intervals in the circumferential direction in a plan view, a container interior vent path formed in the container components and communicating between an opposing surface and a space, and the space are made to be in communication, and by an air suction machine disposed outside the container and connected to a lower end portion of the center vent path, unnecessary air present inside the mold is suctioned through the mold interior vent path and the container vent path that are in communication.

Abstract: Provided is an attaching device and a method for attaching a band-like member to a tire inner surface. A holder that holds the band-like member in a wound state and a paddle are disposed in an inner portion of a tire, and a dispensed portion is pressure-bonded to the inner surface by repeatedly performing: a bonding operation in which a predetermined length dispensed from the band-like member in a wound state toward the inner surface is pressed, by moving the paddle close to the inner surface with no relative rotation of the tire in the circumferential direction with respect to the holder, and is pressure-bonded to the inner surface and a dispensing operation in which, after the bonding operation, the paddle is moved away from the inner surface, and together with relatively rotating the tire in the circumferential direction, a new dispensed portion is formed.

Abstract: In a mold of a tire vulcanization device, a sensor is installed in a state exposed on a tire molding surface, a connector is installed in a state exposed on an attachment surface, the sensor and the connector are connected by a lead wire extending through an interior of the mold. In container components, an inner connector is installed in a state exposed on an opposing surface, and a lead wire connected to the inner connector is extended through an interior of the container components toward an exterior of the container components.

Abstract: In a tire vulcanization device, a vertical position of a container ring is locked at a closed position by a lock mechanism. A pressurizing mechanism is operated so as to decrease a vertical gap between an upper plate and a lower plate. The lower plate is moved upward so that a segment is moved toward a center mechanism by a container ring and sector molds are assembled in an annular shape. A state where a predetermined vertical gap is formed between the container ring and a bolster plate by a vertical connection mechanism is created. An upper side mold disposed on a lower surface of the upper plate is closed by being pressed against an upper surface of each of the sector molds while maintaining a state where the sector molds are assembled in an annular shape.

Abstract: In a rubber temperature measuring device, a temperature sensor and a biasing member are disposed in an installation hole formed in a molding surface of a mold. The temperature sensor is biased by the biasing member and a temperature detecting unit at a tip end projects from the molding surface and is not in contact with the mold. The mold is closed and vulcanized in a state in which a green tire making contact with the temperature detecting unit presses the temperature sensor against biasing force of the biasing member and an opening portion of the installation hole is blocked by the temperature detecting unit. Temperature data detected by the temperature detecting unit is input to a control unit disposed outside the mold through a communication line extending in a communicating hole communicating with the installation hole.

Abstract: A tightening apparatus for a dental implant includes a torque wrench and a slip detection device. The torque wrench includes a tightening part engageable with an abutment of the implant and a tightening torque detector for detecting tightening torques generated when the abutment is screwed to the fixture. The slip detection device includes a slip determiner and an indicator. The slip determiner samples an amount or rate of change of the torques detected by the torque detector in every predetermined period, to sequentially compare the amount or rate of change of the torques in a prior predetermined period with that in a subsequent predetermined period, and to determine whether or not the latter amount or rate is smaller than the former amount or rate. The indicator activates when the slip determiner determines that the latter amount or rate of change is smaller than the former amount or rate of change.
