摘要:
A semiconductor target for use in a pickup tube includes a semiconductor substrate, on one side of which is formed arrays of a plurality of depressions and which has a corresponding number of PN junctions formed along the depressions.
摘要:
A photoconductive structure includes first layers of a photoconductive material having one spectral response region and second layers of a different photoconductive material having a different spectral response region laminated one on another either alternately or in a predetermined order at least two times, the thickness of each layer being such that light penetrates therethrough, i.e., less than 2 Mu . Low-resistivity photoconductive materials can be used to provide multilayer structures having a high sensitivity to a predetermined range of wavelengths of light, for example, to the red-light region and a wide spectral region.
摘要:
A method of preparing a vapor-deposited layer having photoconductivity on a substrate, in which lead oxide and at least one of the compounds selected from the group consisting of chalcogenides of Cu, Ag, Zn, Cd, Hg, Ga, In, Tl, Ge, Sn, Sb and Bi are evaporated simultaneously from separate sources, and are vapor-deposited on the substrate. This vapor deposition is carried out in an oxygen or oxygen-containing atmosphere.
摘要:
A METHOD OF MANUFACTURING A PHOTOSENSITIVE DEVICE WHICH COMPRISES THE STEP OF BOMBARDING UNDER VACUUM ELECTRON BEAMS OF 10 TO 1,000 EV. ONTO THE SURFACE OF A LEAD MONOXIDE LAYER WHICH HAS BEEN SUBJECTED TO AFTERTREATMENT BY CARRYING OUT AN ELECTRICAL DISCHARGE THROUGH AN OXYGEN-CONTAINING ATMOSPHERE THEREBY TO REMOVE EXCESS OXYGEN ATOMS DEPOSITED ON THE SURFACE OF THE LEAD MONOXIDE LAYER.
摘要:
An image intensifier vidicon which is divided by a semiconductor target into an image section, the inner surface of the face plate of which is coated with an electron-emissive layer and a scanning section, wherein said semi-conductor target includes a semiconductor substrate, a plurality of PN junctions formed therein, an accelerating layer formed on the electron incident side of said target, and a scanning surface which is protected from contamination by alkali metals constituting the electronemissive layer by means of insulation rings provided in the scanning section. One of the insulation rings also set the critical spacing between the target and a mesh electrode.
摘要:
In a color television image pick-up device the light received through an objective lens is divided to follow two discrete paths, a part of the light being supplied to a brilliance image pick-up and the other part of the light being supplied through a Magenta filter to a chromaticity image pick-up tube including a stripe filter formed on the inner surface of a face plate and consisting of alternate monochromatic portions of red or blue color and transparent portions, thus obtaining color television signals from the output from two image pick-up tubes.
摘要:
A photoelectric converting device comprising a semiconductor substrate in one surface of which there are provided a plurality of junctions in a mosaic arrangement. In the portions of the opposite surface of said substrate which are in registration with and face said junctions is provided means to decrease effectively the surface recombination of minority carriers created due to the introduction of a light.
摘要:
A semiconductor photoelectric converting device comprising a semiconductor substrate having a plurality of PN-junctions separately formed therein in three groups according to their different depths so as to allow the red, green and blue components of a light from a foreground object to be separated by said groups respectively.
