Abstract

DC60 (18/08/40) Phosphor class These are the first and second indications. The phosphor is created on the inner surface of the face plate. The back plate will be provided with a receiver unit. First and second light For the detection of light signals From the phosphor layer as an indication The first and second respectively, each receiving the first optical signal. There will be a part that is the first light accumulating sheet. Which will emit light rays absorbed Which has the peak wavelength in radiating light That is equal to or shorter than Long wave to shine Of each phosphor layer, one truly indicator signal, each receiving a second optical signal. There will be a second light accumulating sheet. Which emits absorbed light radiation which has the peak wavelength to emit light That is equal to or shorter The optical wavelengths of each phosphor layer are literally the second indication, what is arranged between each. Second collector sheet And the back plate is a filter Which transmits light signals from the phosphor layer Which is the second indication And to block the light of the indication From the phosphor layer that is the first indication of the phosphor layer These are the first and second indications. The phosphor is created on the inner surface of the face plate. The back plate will be provided with a receiver unit. First and second light For detecting signal light From the phosphor layer as an indication The first and second respectively, each receiving the first optical signal. There will be a part that is the first light accumulating sheet. Which will emit light rays absorbed Which has the peak wavelength in radiating light That is equal to or shorter than Long wave to shine Of each phosphor layer, one truly indicator signal, each receiving a second optical signal. There will be a second light accumulating sheet. Which emits absorbed light radiation which has the peak wavelength to emit light That is equal to or shorter The optical wavelengths of each phosphor layer are literally the second indication, what is arranged between each. Second collector sheet And the back plate is a filter Which transmits light signals from the phosphor layer Which is the second indication And to block the light of the indication From the first indicator of the phosphor layer
