Abstract:
A tire/wheel assembly in which a run-flat support member 3 is inserted into a cavity of a pneumatic tire 2, where the run-flat support member 3 includes a circular shell 4 in which the outer circumferential side thereof is used as a support surface and the inner circumferential side thereof is opened to have two leg portions, and elastic rings 5 supporting the ends of the two leg portions on a rim. An air path 7 is provided in the elastic ring 5 so as to interconnect the inside and outside of the run-flat support member 3.
Abstract:
A chassis has plate supporting pillars, insertion holes with engagement pegs, and an aperture brim connected to a lens holding unit. A photographic element package is attached to a plate. Contact surfaces are formed in the aperture brim so that distances from a center axis of a lens holding unit to the two adjacent contact surfaces of the aperture brim are the same as the distances from adjacent standard surfaces of the photographic element package to the center of the photographic element. Plate springs are provided on the mounting member, so that the photographic element package standard surfaces press against the contact surfaces. Plate springs press the plate against the plate supporting pillars. Insertion plates with engagement holes are provided on the mounting member, so that the insertion plates are inserted into the insertion holes and the engagement pegs engage the engagement holes, thereby completing the mounting of the plate on the chassis.
Abstract:
There is provided a magnetic recording/reproducing apparatus which has an improved reliability for a reproduced signal by eliminating a deformation in a reproduced signal waveform due to a residual magnetization generated in a magnetic head. The magnetic recording/reproducing apparatus has a magnetic recording medium including a magnetic film to which information is magnetically recorded and a thin-film magnetic head including a magnetic pole and a coil provided around the magnetic pole. A current supplying circuit supplies a current to the coil so that a magnetic state of the magnetic pole is stabilized. The current is supplied to the coil after a recording operation has been completed by the thin-film magnetic head. The current may demagnetize the magnetic pole of the magnetic head, or stabilize the magnetic state of the magnetic pole.
Abstract:
A cylindrical body is formed by mounting a carcass to the outer periphery of a film formed of a thermoplastic resin or a thermoplastic resin elastomer composition. A molded body is formed by fitting bead rings on opposite width direction ends of the cylindrical body, and the molded body is sucked on a transfer mold's inner periphery. After a rigid inner mold is inserted into the molded body, suction stops and the molded body is transferred to the inner mold's outer periphery. Opposite carcass ends in a width direction are turned up on the inner mold, while other tire members are stacked on the molded body's outer periphery to mold a green tire. The tire and inner mold are placed in disposed inside a heated curing mold and the film is inflated to cure the tire and bond the film to the inner peripheral tire surface to form an inner layer.
Abstract:
A pneumatic tire including a cylindrical annular structure, a rubber layer that will become a tread portion provided along a circumferential direction of the annular structure, on an outer side of the annular structure, and a carcass portion including fibers covered by rubber, provided on both sides in a direction parallel to a center axis (Y-axis) of a cylindrical structure including the annular structure and the rubber layer. In a meridian cross-sectional view of the structure, an outer side of the rubber layer and the outer side of the annular structure have the same form.
Abstract:
A method for separating and removing a rigid core when building a tire. When the rigid core body is to be separated and removed from the inside of the tire, the method includes removing a core holding mechanism and upper and lower support plates; transferring the tire to a support table; raising a second core separation/removal mechanism; horizontally pulling a first type of segment groups until separated from the inner surface of the tire; lowering the first type of the segment groups below the support table; lowering a first core separation/removal mechanism to the center of the height position of the rigid core body; horizontally pulling the second type of the segment groups until they are separated from the inner surface of the tire; transferring a second type of the segment groups with a second core separation/removal mechanism, and conveying the tire to the subsequent process.
Abstract:
A pneumatic tire including: a cylindrical annular structure; a rubber layer, which will become a tread portion, provided along a circumferential direction of the annular structure on an outer side of the annular structure; a carcass portion provided on at least both sides in a width direction of the cylindrical structure including the annular structure and the rubber layer; and an extending portion that extends from both sides in the width direction of the annular structure farther outward in the width direction than a ground contact edge on the outer side in the width direction of the tread portion, and that is provided in plurality on both sides in the width direction along the circumferential direction of the annular structure.
Abstract:
A cylindrical-shaped body is formed by mounting a carcass to the outer peripheral side of a film formed of a thermoplastic resin or a thermoplastic resin elastomer composition, a primary molded body is formed by fitting bead rings on opposite width direction ends of the cylindrical-shaped body, and the primary molded body is sucked on the inner peripheral surface of a transfer and holding mold. After a rigid inner mold is inserted into the body, suction is stopped and the body is transferred to the outer peripheral surface of the inner mold. Then, another tire member is stacked on the outer peripheral surface to mold a green tire. The tire, from which the inner mold was removed, is mounted inside a curing mold which is heated. The film is inflated and heated to vulcanize the tire, and bonded to the inner peripheral tire surface to form an inner layer.
Abstract:
Provided is a bisplit mold for tire forming capable of avoiding the pinching of the unvulcanized tire at the mold clamping. Also provided is a process for manufacturing a tire by use of the bisplit mold. The bisplit mold includes: a plurality of segments provided to each of the paired containers, and formed by being divided in the tire circumferential direction and; opening-closing means provided to the respective containers, cause the superior and the inferior segments to come close to and separate away from each other, the segments being attached to the pair of containers with vertically bisplit center plates placed between the pair of containers; a superior side plate and an inferior side plate provided respectively to the pair of containers; and vertically bisplit mold pieces provided to the inner sides of the segments.
Abstract:
Provided is a compact casting apparatus capable of producing a high-quality casted product. While the internal pressures of a mold and a hopper are directly reduced by depressurizing means through a pipe and a branch pipe, the mold and the hopper are gradually tilted to fill the mold with a molten metal accommodated in the hopper. After the filling is completed, an open-close gate closes a runner. The molten metal is solidified with only the mold being directly pressured by pressurizing means through the pipe.
