A method for measuring the viscosity of a green compact includes the steps of finding a corrected value V′ of the sample volume of the green compact, where the corrected value V′ of the sample volume is a volume occupied by the inorganic powder in the green compact; finding a corrected value (dh/dt)′ of the sample deformation rate of the green compact, where the corrected value (dh/dt)′ of the sample deformation rate is the difference between the apparent sample deformation rate and the sample deformation rate due to sintering shrinkage; separating a temperature range X in which sintering shrinkage dominates and a temperature range Y in which plastic deformation dominates with respect to the displacement of the green compact; substituting the corrected value V′ of the sample volume for the sample volume V and substituting the corrected value (dh/dt)′ of the sample deformation rate for the sample deformation rate dh/dt in the Gent equation with respect to the temperature range X; and substituting the corrected value V′ of the sample volume for the sample volume V in the Gent equation with respect to the temperature range Y.

A thin glaze layer (2) is formed on a relief surface (1R) to a thickness which leaves recess on the relief surface (1R). A glaze-repellent layer (4) capable of repelling the glaze slurry is then formed on the surface of the thin glaze layer (2) to form a coated substrate. The glaze slurry is affixed to the coated substrate for forming a glaze slurry layer (5) for completing the glazing.

A solid-electrolyte fuel cell stack comprises three-layered films and separators alternately stacked with each other. Each of the three-layered films comprises a solid-electrolyte film, a fuel electrode and an air electrode with the solid-electrolyte film interposed between the fuel electrode and the air electrode. The three-layered film and the separator are bonded together with a glass bonding agent and a ceramic bonding agent separately interposed therebetween.

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.
