Abstract: The present invention provides an X-ray generating tube including a transmission target having a minute focal spot. The X-ray generating tube includes a transmission target having a first surface and a second surface opposite to the first surface, the first surface being irradiated with an electron beam, and the target radiating X-rays from the second surface; an electron emitting source emitting the electron beam in such a manner that the electron beam obliquely enters the first surface; and a tubular forward shield member located at the second surface side of the target to define an extraction angle of an extracted X-ray beam. The forward shield member is disposed such that a central axis of the electron beam and a central axis of the X-ray beam whose extraction angle is defined are located at the same side with respect to a virtual normal plane perpendicular to the first surface and a projection central axis that is a projection of the central axis of the electron beam to the first surface.

Abstract: A chiral smectic liquid crystal device with a good planar homogeneity in a layer normal direction can be constituted by disposing a chiral smectic liquid crystal having no cholesteric phase between a pair of substrates having mutually different characters, particularly in terms of Iso - SmA phase transition temperature. The liquid crystal may preferably have a layer spacing-changing characteristic such that it provides a layer spacing dA at a first transition point where the layer spacing of the liquid crystal begins to decrease on temperature decrease in the vicinity of a transition temperature from SmA phase to SmC* phase and a layer spacing dmin at a second transition point where the layer spacing of the liquid crystal begins to increase on further temperature decrease from the first transition point, satisfying 0.96
