Title: Plane display screen with large electrode interval
Inventor: JIYANNMARUKU SORU
IPC: H01J31/12
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a planar display screen, wherein space between electrodes is wide and inner surfaces of a substrate does not become dirty by supporting a first electrode with a thin substrate and a thick reinforcing plate, and by demarcating an interior space by a peripheral frame disposed between electrodes on the outside of the effective surface of each of the electrodes.

The space 12 can be fixed by a simple peripheral rigid frame 22, by enhancing rigidity of a structure by using the plates 20, 21 fixed to an outer surface of a screen. Further, the space 12 between the electrodes of the screen can be widened by thickening the thickness of the frame 22, while deformation of the screen caused by a pressure difference between the interior and the exterior of the screen can be prevented by giving sufficient rigidity to the screen by the plates 20, 21.  Accordingly, a spacer can be dispensed with, while the pollution of the substrate 10 inner surfaces caused by adhesion, soldering, and the like can be prevented.

IPC: C03C13/04
Filed: 1984-04-27
Abstract: PURPOSE:To enable exact conversion and detection of the quantity of the UV rays in the light propagated into an optical fiber in the form of quantity of fluorescence by incorporating a fluorescent material which emits fluoresence by sensing the light of a prescribed wavelength region into at least one layer of the multi-layered structure of the optical fiber. CONSTITUTION:The optical fiber 10 consists of a core 1 made of quartz and a clad layer 2 made of a polymer. About 1,000ppm fluorescent material is incorporated into the layer 2. The top ene and intermediate part are looped plural times and the other end face is connected to a photodetector 11. If the looped part is placed to face a flame F, the light of the flame F is made incident on the inside of the fiber 10 from one end face or the peripheral surface in the intermediate part of the fiber 10 and since part thereof passes the inside of the layer 2, the UV rays included therein are absorbed into the fluorescent material 4 and fluorescence is emitted from the material 4. The fluorescence enters not only the clad layer 2 but also the inside of the core 1, propagates in the core and is captured by a photodetector 11, by which the energy thereof is detected and the flame is thus detected.

Title: Electrophotographic toner
Inventor: NAKAYAMA KOJI
IPC: G03G9/08
Filed: 1993-03-24
Abstract: PURPOSE:To suppress the blocking phenomenon and sticking of the spent toner on the carrier from occurring and to prevent reduction of the image dehsity and the fogging in the non-image area from being generated by allowing a fine-powdery carbon fluoride to adhere to the surfaces of the toner mother particles. CONSTITUTION:The fine-powdery carbon fluoride having a structure represented by the formula CFx, wherein x is the degree of fluorination, and <=0.8mum, particularly <=0.5mum particle size can be used. When the particle size of the fine- powdery carbon fluoride is greater, its adhesion to the toner is reduced and the electrification characteristics of the toner is adversely affected and also the change of the image density is increased and further the preservation stability is reduced due to reduction of the fluidity of the toner. The toner mother particles are obtained by mixing a binding resin, a colorant and a charge controlling agent with each other, melting the mixture, thereafter cooling and solidifying the molten mixture and then pulverizing and classifying the resulting material. In order to allow the fine-powdery carbon fluoride to adhere to the surface of the toner mother particles, the toner mother particles and the fine powdery carbon fluoride are mixed with each other by using a Henschel mixer, etc.
