Abstract:
Provided herein is a non-destructive testing method capable of diagnosing a condition of an object to be tested using a single-pulse ultrasonic wave signal. An attenuation waveform of the single-pulse ultrasonic wave signal received by a receiving section 3 is wavelet transformed by a wavelet transform section 6 to obtain an envelope line A(t) and a phase φ(t) of the attenuation waveform. A temporal change computing section 7 approximates the attenuation waveform by an approximation equation available for computation, using the envelope line A(t) and the phase φ(t) of the attenuation waveform inputted from the wavelet transform section 6, and obtains the temporal change of instantaneous frequency of the attenuation waveform. A diagnosing section 8 diagnoses a condition of the object to be tested, based on the temporal change of the instantaneous frequency computed by the temporal change computing section 7.

Abstract:
Electric power supplying equipment and an electric power receiving device include a primary self resonant coil and a secondary self resonant coil, respectively, resonating through an electromagnetic field to allow the electric power supplying equipment to supply the electric power receiving device with electric power in a non-contact manner. A control device controls a high frequency electric power supply device to control supplying electric power from the primary self resonant coil to the secondary self resonant coil. The control device estimates a distance between the primary self resonant coil and the secondary self resonant coil from an S-parameter S11 varying with the distance between the primary self resonant coil and the secondary self resonant coil, and controls supplying electric power, based on that estimated distance.

Abstract:
In a pneumatic tire of the present invention, a tread reinforcing rubber layer composed of a rubber having larger tensile modulus of elasticity than that of a rubber composing the tread rubber layer and is less stretchable is provided in a thickness direction central area of a tread rubber layer. Because the tread reinforcing rubber layer diminishes the amount of lateral expansion and the amount of vertical compressive deformation when the tread rubber layer contacts the ground, generation of heat in the tread rubber layer can be suppressed. Therefore, in the present invention, the unique tread structure reliably suppresses heat-generation and the rubber of the tread rubber layer exhibits excellent tire wear resistance. As a result, suppression of heat-generation and high tire resistance can readily be achieved simultaneously.

Abstract:
Provided is a pneumatic tire which is provided with a turbulent flow generation projection for generating a turbulent flow at least in a portion of a surface of the tire and has an outer diameter of not less than 2 m The turbulent flow generation projection extends linearly or curvilinearly along a tire radial direction. A relationship of h=√{1/(V/R)}×coefficient κ is satisfied where “h” is a projection height (mm) from the surface of the tire to a most protruded position of the turbulent flow generation projection, “V” is a speed of a vehicle (km/h), “R” is a tire outer diameter (m), provided that coefficient κ=27.0 to 29.5.
Abstract:
An object of the present invention is to provide a tire for a construction vehicle which suppresses a trouble of the tire by enhancing a heat-radiation characteristic of a tire center portion.A tire for a construction vehicle according to the present invention is provided with a plurality of lug grooves 22 in tread shoulder regions located at the both sides in the width direction of the tire. A plurality of widthwise-extending narrow grooves 24 extending generally along the width direction of the tire and having an end in the width direction of the tire terminated in the tread are disposed in a tire center portion C. This may improve the wear resistance characteristic and to enhance the heat-radiation characteristic by suppressing the decrease of the rigidity of the land portion. In addition, an equatorial shallow groove 26 extending in the circumferential direction of the tire is disposed on the tire equator CL. This allows the compressive stress acting on the tire center portion to be relaxed and the area for hear-radiation to be increased.
