Abstract:
A flat display device comprises a vacuum envelope constituted by a back base plate consisting of an elastic metal plate and a display panel and accommodating a thermionic cathode structure and a plurality of electrode structures for controlling the electron beams emitted from the thermionic cathode structure. The thermionic cathode structure is divided into a plurality of sections each including a plurality of coiled thermionic cathode heaters connected in parallel and arranged such that each corresponds to each of picture element regions provided on the back side of the display panel. Voltage supply terminals for supplying power to the parallel coiled heaters in each section are led out through the back base plate via insulating members.

Abstract:
An envelope for hermetically containing various functional elements of an indicator tube is disclosed. The envelope includes a base plate and a transparent cover mounted on a front surface of the base plate to form a chamber with the base plate which contains a plurality of the indicator elements. The cover comprises a channel plate having a transparent upper viewing window and side ridges or walls and a pair of strips to be bonded to the open side ends of the channel plate.
Abstract:
A multi-indicia display device includes a rigid base plate made up of a plurality of sheets of an electrical insulating material laminated together. Electrodes are mounted on the base plate. One of the electrodes is a metal layer coated on the base plate forming a plurality of separate but identical indicia, each indicia comprising a plurality of sections. Metal layer termination pads are coated on the front and back surfaces of the base plate along one edge thereof. Metal film electrical circuitry is coated on the surfaces of the sheets of the base plate and extend through holes in the sheets to electrically connect the electrodes to the termination pads. A transparent cover is mounted on the base plate and extends over the electrodes.

Provided is a linearly polarized ultra-short terahertz wave generating device which has a parabolic barrel mirror installed at one side of a multiple thin film, to generate an ultra-short terahertz wave having single linear-polarized light and uniformly formed output distribution.
Abstract:
This specification relates to a terahertz pulse generator capable of generating ultra-short terahertz pulses by use of electron beams transported through a plurality of foils. The plurality of foils in a shape of disc are arranged in an overlapped state and form a conical shape that diameters of the disc-shaped foils sequentially decrease along a direction that the electron beam is transported. Coherent radiation, which is generated as the ultra-short electron beam is transported through the foils in respective spaced gaps of the foils, is propagated toward the outside of the disc-shaped foils and gathered with forming a conical wave surface at edges of the disc-shaped foils. This may result in enhancement of generation efficiency of the terahertz waves.
Abstract:
A mesh electrode adhesion structure includes: a substrate, and an opening defined in the substrate; a mesh electrode on the substrate, and a first combination groove defined in the mesh electrode; and an adhesion layer between the substrate and the mesh electrode. The mesh electrode includes: a mesh region corresponding to the opening defined in the substrate, and an adhesion region in which the first combination groove exposes the adhesion layer.
Abstract:
The present invention relates to a method for manufacturing a plurality of nanostructures comprising the steps of providing a plurality of protruding base structures (104) arranged on a surface of a first substrate (102), providing a seed layer mixture, comprising a solvent/dispersant and a seed material, in contact with the protruding base structures, providing a second substrate arranged in parallel with the first substrate adjacent to the protruding base structures, thereby enclosing a majority of the seed layer mixture between the first and second substrates, evaporating the solvent, thereby forming a seed layer (110) comprising the seed material on the protruding base structures, removing the second substrate, providing a growth mixture, comprising a growth agent, in contact with the seed layer, and controlling the temperature of the growth mixture so that nanostructures (114) are formed on the seed layer via chemical reaction in presence of the growth agent.
