  • Publication number: 20120037287
    Abstract: A heavy duty pneumatic tire comprises a tread portion provided with a circumferentially continuously extending longitudinal groove disposed on each side of the tire equator, and oblique grooves extending axially inwardly from the longitudinal groove at an inclination angle of 20 to 40 degrees with respect to the tire axial direction. The longitudinal groove is provided with a sound insulation wall disposed therein so as to rise from the groove bottom. The sound insulation wall extends continuously in the circumferential direction in a zigzag manner so as to have axially inner points and axially outer points at turning points of the zigzag. The distance between the sound insulation wall and the axially inner edge of the longitudinal groove is varied periodically in the tire circumferential direction so that the distance becomes minimal at the junctions of the longitudinal groove with the axially inner oblique grooves.

  • Patent number: 7579907
    Abstract: A switching amplifier of the invention boasts of an enhanced SN ratio in its output and an increased amplitude limit value in its input signal. The switching amplifier has a quantized signal generating section that converts an input signal to generate a quantized signal in the form of a PDM or PWM signal and a constant-current-outputting current amplification section that current-amplifies the quantized signal outputted from the quantized signal generating section. The quantized signal generating section and the current amplification section are formed by the same process. Another switching amplifier of the invention is inexpensive and is not affected by voltage fluctuations in the supply voltage.
