摘要:
A mold (22) includes a bead ring (32). The bead ring (32) includes a side forming surface (34), a bottom forming surface (36), a support surface (38) for a bladder, and a guide surface (40) for a bladder. The support surface (38) is positioned on an inside in a radial direction of the bottom forming surface (36). The support surface (38) is extended in the radial direction. A distance (L2) of the support surface (38) is equal to or smaller than 5.0 mm in the radial direction. The guide surface (40) is positioned on an inside in the radial direction and an outside in an axial direction from the support surface (38). The guide surface (40) is inclined inward in the axial direction from the inside in the radial direction toward an outside in the radial direction. An angle θ of the guide surface (40) to the radial direction is equal to or greater than 15 degrees and is equal to or smaller than 75 degrees. In an expansion, a bladder (B) is erected by the guide surface (40). By a further expansion, the bladder (B) is supported by the support surface (38).
摘要:
A mold for a pneumatic tire with an inflatable bladder is disclosed with a pair of axially spaced bead portions each with a bead bottom surface extending from a bead toe toward the axially outside of the tire. The bladder is disposed inside the green tire in the mold and inflated to press the green tire against the inside of the mold. The mold comprises a pair of bead rings and each bead ring is provided with a bead bottom molding face for molding said bead bottom surface. Each bead ring is provided radially inside the bead bottom molding face with a protrusion protruding axially inwardly from the axially inner end of the bead bottom molding face so that the axial extent of the protrusion from the axially inner end of the bead bottom molding face is in the range of from 0.05 to 0.4 times the axial distance between the axially inner ends of the bead molding faces.

摘要:
A pneumatic tire comprises a toroidal carcass ply composed of cords arranged radially at the same angle to the tire equator and extending continuously between the bead portions through the tread portion and sidewall portion, and the carcass ply is increased in thickness partially in at least a tire shoulder portion. A method of making the tire comprises a step of heating a raw tire, wherein a raw carcass ply is composed of cords having at least two different heat-shrinkage-percentages.

A radiographic imaging system includes an imaging apparatus which takes a radiographic image of a subject and outputs image data of the radiographic image; an image processing apparatus which performs image processing of at least one of an exposure field recognition process and a trimming process on the image data of the radiographic image; an image processing information storage apparatus which stores the imaging conditions of the radiographic image and image processing information which indicates the image processing and its applicable range in an associated manner; and an image processing information search apparatus which searches for image processing information according to imaging conditions of current imaging, among the image processing information of past imaging stored. The imaging apparatus changes a range of radiation exposure irradiated from a radiation source in accordance with the applicable range of the image processing of the past imaging contained in the image processing information retrieved by the image processing information search apparatus.
摘要:
An image processing apparatus capable of clipping a diagnostic region while retaining the pixel information of the original radiographic image even when the subject is imaged aslant. The image processing apparatus applies trimming processing to a radiographic image acquired by an imaging apparatus for acquiring a radiographic image of a subject and includes an image rotation unit for rotating the radiographic image so that the subject is aligned with a given direction to produce a display image, a diagnostic region designation unit for designating a first diagnostic region clipped with a diagnostic region designation frame represented by a rectangle for the display image, and a trimming processing unit for calculating a second diagnostic region in the radiographic image from a rotation amount of the display image and diagnostic region information representing the first diagnostic region and applying trimming processing to the radiographic image to clip the second diagnostic region.
摘要:
A method of molding an elastomeric article comprises: putting an elastomeric article in a mold; softening the elastomeric article in the mold by heating the elastomeric article; pressing the elastomeric article against the mold by pressurizing an inside of the elastomeric article by letting a fluid therein; and changing the pressure of said fluid in a short cycle so as to beat the elastomeric article against the mold repeatedly.
