摘要： Disclosed is a pneumatic tire effectively controlling uneven wear occurring in the vicinity of a main groove even if a groove width of the main groove is narrowed due to change in tread radius during inflation. In the pneumatic tire, with regard to the main groove having its groove width narrowed during inflation among a plurality of main grooves provided on a tread surface, both groove walls are inclined so that the groove width becomes wider toward the groove bottom, and a protrusion dividing the groove space in the tire width direction is provided at the groove bottom.

摘要： An evaluation method for pneumatic tires and a system thereof, is provided, capable of appropriately evaluating an adverse effect, such as deterioration, of tire temperature by expressing severity of a temperature imposed on a member of tire made of rubber or the like in quantitative and convenient manners. Detection counts are calculated for each detected temperature according to a detection counts calculating unit 102 based on information of temperatures of pneumatic tires detected by a temperature sensor of a temperature detector 101. Temperature severity numbers of the pneumatic tires are calculated from a computing equation by a severity calculating unit 104 based on the detection counts and contribution coefficients of deterioration of tire rubber with temperatures stored in a contribution coefficient storage 103 as parameters. Using the calculated temperature severity number, a determination unit 105 determines thermal deterioration of the tire.

摘要： A pneumatic tire has a plurality of circumferential main grooves extending in a tire circumferential direction and a plurality of ribs partitioned by the circumferential main grooves in a tread portion. When viewing a cross-section from a tire meridian direction a contact patch of the center ribs is formed from a smooth curved line forming a convex on an outer side in a tire radial direction and a contact patch of the shoulder rib is formed from a smooth curved line forming a convex on an inner side in the tire radial direction. The curved line of the center ribs and the curved line of the shoulder rib have a point of intersection. A distance between an extended line of the curved line of the center ribs and the curved line of the shoulder rib increases from the point of intersection towards an outer side in a tire width direction.

摘要： A video signal reproduction apparatus reproduces a chrominance signal which has been converted to a low frequency band and recorded on a magnetic tape. The low frequency chrominance signal read out from the magnetic tape is first subjected to phase recovery processing. Then, frequency conversion is carried out for the phase recovered chrominance signal to generate a reproduced chrominance signal. Thus, phase recovery is carried out prior to frequency conversion, and an oscillation signal can be directly supplied to the frequency converter from a voltage controlled oscillator in a phase controller, thereby achieving an accurate frequency conversion. This structure allows an extra frequency converter or a complicated band pass filter to be omitted.

摘要： A parallel processing device consists of plural processing pipelines arranged in parallel, decoders which decode processing instructions and outputs them to respective processing pipelines, and a general register in which the processing instruction to be outputted to each of decoders is written in one of its registering sections, or a multiple-port register. The processing instructions are written in the general register or the multiple-port register, wherein the respective registering sections storing the processing instructions are simultaneously specified either by a parallel instruction device, a one-dimensional expanded instruction register, or a two-dimensional expanded instruction register so that their contents are simultaneously outputted to make each of the processing pipelines perform simultaneously. Thus, the simultaneous concentration of a large amount of information can be avoided during the parallel processing operation, eliminating the need for a bus with a large bit number.
