Abstract:
This invention provides a process for improving the field emission of an electron field emitter comprised of an acicular emitting substance such as acicular carbon, an acicular semiconductor, an acicular metal or a mixture thereof, comprising applying a force to the surface of the electron field emitter wherein the force results in the removal of a portion of the electron field emitter thereby forming a new surface of the electron field emitter.
Abstract:
Disclosed is a light-emitting device comprising a light-emitting element (10) which emits lights having a main emission peak wavelength in a range from near ultraviolet region to visible region and phosphors (11). The light-emitting device comprises two or more kinds of phosphors (11) which either have luminescent centers of direct transition type or are directly excited by the light-emitting element (10).
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a cathode assembly including a process of forming an electron field emitter by printing paste, with the use of the screen printable paste configured of carbon nanotubes. SOLUTION: The method for manufacturing the cathode assembly including the electron field emitter is provided by forming an electron field emitter by using the paste which contains carbon nanotubes as a solid content and can perform screen printing, wherein the carbon nanotubes in the paste used for forming the electron field emitter is less than 9 wt.% to total weight of the solid content. Or, the method may include processes of: making the electron field emitter in contact with a material; removing a part of the electron field emitter by peeling off the material or realigning the electron field emitter; and forming a new surface of the electron field emitter.

Abstract:
PROBLEM TO BE SOLVED: To provide a lead for absorbing an iterative bending stress to be generated in a temperature cycle, and to provide its stress dealing method. SOLUTION: A pair of leads 1, a semiconductor element 2 mounted on each lead 1, a pair of leads 3, and a semiconductor element 4 mounted on each lead 3 are mounted on a printed circuit board 5. A semiconductor element connection terminal 1a of each lead 1 is extended from the semiconductor element 2 outward, and one end of an intermediate inclined part 1b of the lead 1 is bent inward so that a board connecting terminal 1c can be configured. Therefore, the overall length of the lead 1 is made long so that the stress can be distributed and absorbed, and that a tape carrier package can be made compact. COPYRIGHT: (C)2005,JPO&NCIPI
