摘要:
A notched transmission belt has a plurality of notches whose bottom in a cross-section taken along a plane orthogonal to the width direction of the belt includes a linear portion at a center, and recessed curved portions continuously formed at both sides of the linear portion.

Provided are a fine silver particle dispersion which exhibits low temperature sinterability and in which fine silver particles are uniformly dispersed in a variety of solvents (and especially highly polar solvents); fine silver particles that exhibit low temperature sinterability and excellent dispersion stability in a variety of solvents (and especially highly polar solvents); a dispersion obtained using the fine silver particles; and a method for producing same. The fine silver particle dispersion is characterized by containing fine silver particles, a short chain amine having 5 or fewer carbon atoms, and a highly polar solvent and in that the partition coefficient (log P) of the short chain amine is −1.0 to 1.4.

A friction transmission belt includes a belt body looped over a pulley, and transmitting power. The belt body includes a rubber composition in which at least one of montmorillonite and magnesium carbonate is mixed. The friction transmission belt includes a fabric layer coating at least a surface, of the belt body, making contact with the pulley. The fabric layer has a portion making contact with at least one of the montmorillonite and the magnesium carbonate mixed into the rubber composition.

A method of manufacturing a power transmission belt includes: molding and vulcanizing an endless tension member layer in which a cord extending in a belt length direction is embedded; molding and vulcanizing a rubber member for a compressed rubber layer; and bonding together the tension member layer that has been vulcanized and the rubber member, that has been vulcanized, for the compressed rubber layer.

A friction transmission belt includes a belt body, formed of a rubber composition, looped over a pulley, and transmitting power. The friction transmission belt includes a reinforcing fabric wrapping at least a surface, of the belt body, in contact with the pulley. The reinforcing fabric is a knitted fabric, and on the surface of the belt body in contact with the pulley, a wale direction of the reinforcing fabric is a direction in which the friction transmission belt travels.

The tension of a belt is determined accurately at a low cost. A natural-frequency measurement device is configured to measure, in a belt transmission system including at least two pulleys between which a belt is stretched, the natural frequency of the belt based on a vibration generated by hitting a portion of the belt stretched between two adjacent ones of the at least two pulleys, and includes: an acceleration sensor attached to the portion of the belt to sense acceleration resulting from the vibration of the belt; and a measuring instrument configured to measure the natural frequency of the belt based on the acceleration sensed by the acceleration sensor. The measuring instrument transmits the natural frequency to a belt tension calculator which determines the tension of the belt based on the natural frequency.
摘要:
A capacitance-type sensor sheet used for measuring an amount of stretch deformation and strain and/or distribution of stretch deformation and strain may include a dielectric layer made of an elastomer, an obverse-side electrode layer laminated on the obverse surface of the dielectric layer, and a reverse-side electrode layer laminated on the reverse surface of the dielectric layer. The obverse-side electrode layer and the reverse-side electrode layer may each contain carbon nanotubes and the average thickness of the each of obverse-side electrode layer and the reverse-side electrode layer may be 0.1 μm or more and 10 μm or less. The obverse-side electrode layer and the reverse-side electrode layer may be formed by applying a coating solution containing carbon nanotubes. The obverse-side electrode layer and the reverse-side electrode layer may each include a plurality of band-shaped bodies.
摘要:
A power transmission belt has an uneven surface of rubber which when the power transmission belt is wound around a flat pulley, comes in contact with the flat pulley. The uneven surface has projected parts each having a flat top surface.
摘要:
A friction drive belt has a pulley contact portion of a belt body, and at least the pulley contact portion is made of a rubber composition. Numerous pores are formed in a surface of the pulley contact portion of the belt body, and numerous small protrusions having an average height of 4-40 μm are formed to protrude from the surface.
