Abstract: A method for manufacturing electron emitting devices each having electrodes formed on a substrate and an electroconductive thin film connected between a pair of electrodes and having an electron emitting region is provided which can manufacture electron emitting devices having an excellent uniformity of electron emitting characteristics by improving the formation of liquid droplets to be dispensed to the substrate. In the manufacturing method, the substrate formed with the electrodes is subjected to a hydrophobic process using a silane coupling agent which contains two or more acetoxy groups in a molecule, and thereafter liquid droplets containing material for forming the electroconductive thin film are dispensed to the substrate. An image of excellent uniformity can be displayed by adopting electron emitting devices manufactured in the above manner to an image display apparatus.

Abstract: An electron-emitting device comprises a pair of opposing electrodes formed on a substrate, an electroconductive film having a fissure arranged between the pair of electrodes, and at least a film having a gap and containing carbon as a main ingredient, arranged at an end portion of the electroconductive film facing the fissure. The fissure is a region of 95% or more of a length in the fissure direction, has a width of from 60 nm or more to 800 nm or less, and has a difference of 300 nm or less between a maximum value and a minimum value of the width, thereby providing high withstanding voltage without forming branched fissure.

Abstract: Lipid is determined quantitatively by treating a sample with a surfactant in an aqueous medium to obtain a liquid sample dispersion, then reacting the dispersion with a reagent containing cupric ion and bicinchoninic acid, and measuring a colored state developed by complex formation of bicinchoninic acid with cuprous ion formed from cupric ion in the presence of lipid. This method can be effectively applied to determination of amphiphilic lipid having a tendency of gathering in an aqueous medium. Further, two different species interfering with each other in quantitative determination thereof are determined respectively by conducting two different determination methods on the same sample followed by calculation using the values obtained.
