Abstract:
The invention provides a tire condition information collection apparatus and a relay apparatus thereof, which corrects a predetermined physical quantity within tire by use of a predetermined physical quantity outside tire in a vicinity of tire to inform of the corrected physical quantity.An air pressure and temperature of tire are detected by a detection apparatus 10 provided in each wheel 2. The detection data is transmitted from the detection apparatus 10 to a relay apparatus 20 disposed in the vicinity of each wheel by electromagnetic wave of a first frequency. When receiving the transmitted data, the relay apparatus 20 detects an atmospheric pressure and temperature in the vicinity of the wheel 2, and transmits the data to a main apparatus 30 along with the detection data received from the detection apparatus 10. The main apparatus 30 corrects the detection data of the detection apparatus 10 by use of the detection data of the relay apparatus 20, and displays the information obtained by applying the correction on a display panel to inform the driver of the information.

Abstract:
Disclosed is a mounting structure of a tire monitoring device, in which communication failures due to a conductive support core member can be prevented. The tire monitoring device which transmits information of the inside of a tire by using radio waves is mounted on a conductive support core member which is placed within the cavity of a pneumatic tire and is formed in a hollow structure over a peripheral portion of a rim. At this time, the tire monitoring device is disposed on a sidewall of the support core member or in a channel on a load support surface of the support core member, and a transmission antenna of the tire monitoring device is disposed outside of the support core member.
Abstract:
A fertilized ovum is recovered from an upper portion of a magnum of an oviduct of a dead hen 60 to 80 minutes after oviposition. The fertilized ovum is placed in a container containing a thin albumen. A yolk of the ovum is covered with a sheet of gauze, and the ovum is cultured up to the blastoderm stage (stage X) in the container which is covered with a sheet of plastic film that is held by a rubber band.
Abstract:
Provided is a run-flat support for pneumatic tire, which support is improved in durability while still achieving a lightweight. A run-flat support 1 is constituted of an annular shell 2, and elastic rings 3. In a lateral cross section of the annular shell 2, the annular shell 2 has: an outer circumferential side formed in a plurality of convex support potions 2a each bulging outward, and a concave linking portion 2b linking the convex supporting portions 2a; and a pair of right and left leg portions 2c extending radially inward respectively from the supporting portions 2a on the corresponding sides in a bifurcating manner. The elastic rings are mounted respectively on ends of both leg portions of the annular shell 2. The body of the annular shell 2 is formed of metal or ceramics, and a fiber reinforced resin layer 4 is attached at least to an inner circumferential surface of the linking portion 2b, the fiber reinforced resin layer 4 including reinforcing long fibers which arranged to intersect with the circumferential direction.
Abstract:
A run-flat support body and a method assembling the same that improves reliability during running by eliminating mechanical joint components and realizes weight reduction and uniform mass-production are provided. The run-flat support body of the present invention comprises a pair of elastic rings fitted to a rim of a wheel and an annular shell bridging between these elastic rings. In the run-flat support body, the elastic rings and the annular shells are integrally joined, at least one discontinuous spot is provided in a circumference of the annular shell and the elastic rings, a connection structure is formed in which butted ends of the annular shell are joined together by welding, and joining between the annular shell and the elastic ring is partially released in the vicinity of a butted position of the annular shell. When the run-flat support body is inserted into a cavity portion of a pneumatic tire and the butted ends of the annular shell are joined together by welding, the welding work on a portion covered by the elastic ring is performed in a state where the elastic ring is retreated from the butted position of the annular shell.
Abstract:
A tire/wheel assembly comprising a wheel having a rim, a pneumatic tire mounted on the rim of the wheel and a noise reduction interior member disposed in the cavity of the pneumatic tire. The noise reduction interior member includes left and right elastic rings fitted to the rim and an annular body attached between the elastic rings. The annular body is configured such that an annular cavity portion surrounded by the noise reduction interior member and the pneumatic tire has a cross-sectional area that varies in a circumferential direction of the tire.
Abstract:
A process in which a self-sealing pneumatic tire consisting of a pneumatic tire after vulcanization molding furnished with a sealant layer being uniform without thickness irregularity and a cover sheet layer therefore is produced without the use of an organic solvent and expensive apparatus; and an apparatus therefore. The process is characterized by sequentially performing the operations of injecting a viscous sealant material onto the internal surface of a pneumatic tire (T) after vulcanization molding; diffusing the sealant material into a sheet form by centrifugal force while rotating the pneumatic tire (T) around the tire axis to thereby form a sealant layer (11); injecting a cover material of uncured rubber material or resin material onto the inside surface of the sealant layer (11); diffusing the cover material into a sheet form by centrifugal force while rotating the pneumatic tire (T) around the tire axis to thereby form a cover sheet layer (12); and irradiating the cover sheet layer (12) with electron beams, infrared rays, ultraviolet rays or ultrasonic waves to thereby harden the same.
