    • A method of processing electron emitting devices for electron beam sources, wherein the electrons emitted from the electron beam source have an axial symmetric distribution of emitted electrons include determining a crystal axis direction of the crystal bar used as the material for the electron beam source, and cutting out chip material in such a manner that the longitudinal direction of the axis of the electron emitting device coincides with the crystal axis direction of the crystal bar. As a result, the emitted electrons becomes symmetrical to the axial direction, forming an axially symmetrical distribution, and a uniform electron irradiation on a specimen can be achieved in electron microscopes, electron beam inspection and measuring apparatus, electron lithography systems, and the like.

    • A head-up display includes a projector which projects an image light and a hologram lens which diffracts and reflects the projected image and form a virtual image located ahead of a windshield. The hologram lens has a vertical diffraction characteristic which is equivalent to a hyperbolic or parabolic-curve mirror along a line formed by the intersection of the hologram lens and a vertical plane which includes an axis of the image light and a horizontal diffraction characteristic which is equivalent to a parabolic or elliptic curve mirror along a line which is formed by the intersection of the hologram lens and a horizontal plane which includes the axis of the image light. When the hologram is directly attached on a curved windshield which has a focal length fs (in case it is a mirror), the focal length fo of the hologram and the former focal length fs has the following relationship; 1/fo=1/fh+1/fs, where fh is a focal point when the hologram is flat.
