    Abstract: An optical recording medium includes in sequence a transparent substrate, a light-reflecting layer, a transparent intermediate layer and a light-absorbing layer. The light-reflecting layer and the light-absorbing layer are respectively formed as a layer of an organic coloring matter. The light-absorbing layer can cause deformation for recording information accompanied with a local charge in thickness of the transparent intermediate layer in response to a recording beam indicated to the light-absorbing layer through the transparent substrate. The transparent substrate, the light-reflecting layer, the transparent intermediate layer and the light-absorbing layer in combination constitutes a multilayer optical element with respect to a reproducing beam having a prescribed wavelength and incident to the light-absorbing layer through the transparent substrate, the multi-layer optical element showing a minimum reflectance and a maximum reflectance of the reproducing beam at an incident surface of the optical recording medium at different thicknesses of the transparent intermediate layer. The transparent intermediate layer is formed in a thickness providing a mediate reflectance between the maximum and minimum transmittances. At the record pit, the multi-layer optical element is converted into a fresh element providing a successive reflectance change including a higher and a lower reflectance with respect to the reference reflectance at non-record parts, due to the change in thickness of the transparent intermediate layer.

    Abstract: PROBLEM TO BE SOLVED: To suppress reduction in the emitted electron amount with lapse of time and unstability. SOLUTION: When an electron emitting element is manufactured or adjusted, or prior to normal drive, a voltage V1 having following relationship with the maximum value V2 of a normal driving voltage is applied between electrodes. Where a current I that is carried in accordance with applying a voltage V is I=f(V), and f'(V) is a differential coefficient in the voltage V, an expression I satisfies f (V1)/ V1.f'(V1-2f(V1)}>F(V2)/ V2.f'(V2-2f(V2)}. Where applying the voltage V1 is completed and then the voltage V2 is consecutively applied twice in a form of a pulse, the first time value in the right side of the expression I is Xn-1 and the second time value is Xn, an expression II satisfies (Xn-1-Xn)/Xn-1

    Abstract: PROBLEM TO BE SOLVED: To further stabilize an electron emitting characteristic of an electron emitting element. SOLUTION: Before normally driving a cold cathode electron emitting element driven by voltage of ordinary driving voltage not more than Vi, pulse voltage having a wave height value being voltage Vs not more than Vf is applied in the first place, and afterwards, there is applied a pulse voltage having a wave height value that changes until the wave height value becomes voltage Vmax not less than Vi, and after applying pulse voltage having a wave height value of Vmax by one time or more, ordinary driving is performed.

    Abstract: PROBLEM TO BE SOLVED: To provide stable electron emitting characteristics of high efficiency by providing first and second carbon films on a substrate, providing first and second electrodes for electrically connecting to respective carbon films, applying voltage on the second electrode higher than that applied on the first electrode and containing a nitrogen in the carbon films to be connected. SOLUTION: This electron emitting part 5 consists of a second interval 6 formed on a part of a conductive film 4 and a carbon containing film (carbon film) 10 covering a substrate 1 in the second interval 6 and the conductive film 4 near the second interval 6. A voltage is applied on an element electrode 2 higher than that applied on an element electrode 3. By further applying a high voltage on an anode electrode, electrons are emitted from the electron emitting part 5 to the anode electrode. A nitrogen is contained in the carbon film 10 connected to the element electrode 2. By controlling the ratio of the number of nitrogen atoms to the number of carbon atoms (the number of nitrogen atoms/the number of carbon atoms) at 2/100 or more to 15/100 or under, driving stability with high efficiency is enhanced.
