Pneumatic tire tread
A pneumatic tire tread capable of mitigating air column resonance and maintaining drainage performance while ensuring that the flexible fences are abraded to a similar extent to the tread portion is formed from a rubber composition, and has a tread portion in which a primary groove is formed and multiple flexible fences is formed in the primary groove; the flexible fences are formed from at least a rubber composition for fences that is different from the rubber composition for the tread portion; the rubber composition for fences of the flexible fences has an abrasion index that is more than or equal to twice the abrasion index of the rubber composition of the tread portion; and the rubber composition for fences comprises a filler composition that is based on (a) a diene elastomer, (b) a reinforcing filler selected from the group consisting of carbon black, inorganic fillers, organic fillers, and mixtures of said fillers, which has a bet specific surface area of less than 100 m2/g and is in an amount of between 20 phr and 120 phr, preferably between 30 phr and 100 phr; (c) a plasticizing system selected from the group consisting of liquid plasticizer, hydrocarbon resins and mixtures thereof; and (d) a vulcanizing agent.. .

Pneumatic tire
A pneumatic tire according to the present invention includes, one or more main grooves extending in the tire circumferential direction, and a plurality of lateral grooves extending in the tire width direction, the main grooves and the lateral grooves defining a block row formed by a plurality of blocks, at least one sipe being disposed in each block. Each block has a first cutaway groove with one end opening into a lateral groove located on one side of the block and the other end terminating within the block, a second cutaway groove with one end opening into a lateral groove located on the other side of the block and the other end terminating within the block, and a connecting narrow groove having a groove width narrower than that of the first and the second cutaway groove and connecting the first and the second cutaway groove..

Maneuvering system having inner force sense presenting function
When automatic operation of a slave manipulator 105 that follows manual operation of a master manipulator 101 is bilaterally controlled by means of communication, the force acting on the slave manipulator is fed back to the master manipulator by operating the master manipulator primarily under electrically-driven speed control and the slave manipulator primarily under pneumatically-driven force control. Therefore, in the master manipulator, it is not necessary to compensate for the dynamics and the self-weight of the master manipulator in the motion range of a user, allowing highly accurate, broadband positional control, which is specific to an electrically-driven system, and in the slave manipulator, nonlinearity characteristics specific to a pneumatically-driven system presents passive softness, provides a high mass-to-output ratio, and produces a large force..
