摘要： A heavy duty pneumatic radial tire comprises a radial carcass, a main cross belt and a tread portion, in which the main cross belt is formed by laminating at least three rubberized cord layers so that the cords in each layer are parallel to each other but the cords between the adjoining layers are crossed with each other and extend in opposite directions with respect to an equatorial line of the tire. In such a tire, a pair of cushion rubbers are arranged between the adjoining rubberized cord layers constituting the main cross belt at their both end portions by setting a position relation between mutual cushion rubbers at both belt ends to an optimum value to thereby prevent or control the occurrence of the belt end separation failure.

摘要： A method and system for preventing excessive fuel supply during engine startup, including supplying supplementary fuel during cranking of a cold engine and preventing supply of the supplementary fuel if the engine fails to start running. A solenoid valve in a supplementary fuel supply passage permits the supply of supplementary fuel. A switching device controls the solenoid valve and is grounded by a thermistor that is placed adjacent to a heater element. During cranking, electric current is supplied to the heater element, which progressively increases in temperature to cause the electric resistance of the adjacent thermistor to decrease over a predetermined time, thereby causing the transistor to turn off and deactivate the solenoid valve. Thus, if the engine fails to start within the predetermined time, the supplementary fuel supply is cut off by the solenoid valve, thereby reducing the possibility of excessive fuel enrichment and engine flooding.

摘要： An inexpensive, compact digital radio receiver corrects IQ imbalance, non-orthogonal I and Q phases, and DC offset by a DSP. The digital radio receiver is equipped with an antenna, an RF/IF converter for converting a radio frequency into an intermediate frequency, an IQ separator for separating I and Q, a filter for eliminating a noise such as a radio frequency, a multiplying sampler for sampling the output of the filter, and a digital signal processing unit mainly comprised of the DSP which implements an algorithm for estimating and correcting an IQ distortion and also performs quadrature phase demodulation. The IQ distortion can be removed inexpensively by making use of a part of a standard radio operation, hardly requiring the use of hardware for adjustment.
