    摘要: A dielectric ceramic substrate or block contains, at least, two kinds of metal ions, and a dielectric constant in the substrate or block changes continuously or step by step as a function of position. The metal ions contained in the dielectric ceramic material are, at least, two kinds which are selected from the group consisting of Mg, Ca, Sr, Ba, Zn, Pb, Bi, Y, La, Ce, Nd, Sm, Gd, Er, Ti, Zr, Sn, Si and Mn, and the dielectric constant .di-elect cons. changes in the range of 7.ltoreq..di-elect cons..ltoreq.90. This dielectric ceramic material is used in a dielectric substrate for a stripline device, a dielectric substrate for a monolithic IC and a dielectric block for a polarizer. For example, the dielectric substrate for a stripline device, it is so formed that a dielectric constant at its center portion is constant, and becomes smaller step by step or continuously toward its ends. For forming a stripline on the dielectric substrate, when the characteristic impedance is to be constant, a line width at a center portion of the dielectric substrate is narrow and it becomes wider toward the ends.

    摘要: Timer action is done from the time point t.sub.1, where the detected vehicle speed determined by the vehicle speed signal S.sub.2 is 0, until the time point t.sub.6, where the detected vehicle speed exceeds 0, thereby determining the timer time T. The value of the axle load signal S.sub.1 is transiently held, beginning at the time point t.sub.2 where the period of time X has passed since t.sub.1. When the timer time T is longer than the set timer time T.sub.0, the value of the axle load signal S.sub.1 at the time point t.sub.5, the point chronologically backward by the period of time Y from t.sub.6, is read. Based on this read value, the opening of the control valve is adjusted to vary the assist force. Thus, even when a vibration occurs in the vehicle body during driving, the assist force by the power steering system is made constant, whereby a feeling during steering can be improved.
