Title: Amplifier
Inventor: DANIERU MAAKU DORETSUPUSU
IPC: H04B10/291
Filed: 1991-03-07
Abstract: PURPOSE: To provide a multistage amplifier which operates at a high speed and only requires a low power supply voltage. CONSTITUTION: An amplifier circuit has cascade-connected first and second gain cells. Each gain cell incorporates first and second common-emitter differential transistors, a current source connected to the emitters of the transistors, a plurality of first forward bias serial diodes connected between a power terminal and the base of the first transistor, and a plurality of second forward bias serial diodes connected between the power terminal and the base of the second transistor. The collector of the first transistor of the first gain cell is connected to the base of the first transistor of the second gain cell and the collector of the second transistor of the first gain cell is connected to the base of the second transistor of the second gain cell.  Since the specific resistances of the bias diodes are low, the operating speed of the amplifier becomes faster and the circuit can largely amplify the current within the limit of the power supply voltage.

IPC: H04N1/06
Filed: 1981-04-30
Abstract: PURPOSE:To scan both sides of an original picture sheet by rotating a transparent member, which has a semicylindrical part, around a center shaft, and then scanning both the surfaces of the original picture sheet, equipped on the semicylindrical part, by a light-emitting and photodetecting element on an optical base which moves in parallel to the center shaft. CONSTITUTION:While a semicylinder 5 made of a transparent material is rotated around a center shaft, an optical base 1' is moved in parallel to the center shaft. Then, both the surfaces of an original picture sheet equipped around the semicylinder 5 are irradiated with light from a light source lamp 3' and its reflected light is photodetected by a photoelectric tube 2' and transduced into an electric signal which utilizes the variation in the magnification of a current. Thus, both the surfaces of the original picture sheet are scanned.

Abstract: PURPOSE: To achieve the higher speed of computation by arranging a microlens arrays(MLA) and 4 quadrant detectors in a lattice and an analog computing circuit separately to determine the inclination of a wave front from the output value of the 4 quadrant detector. CONSTITUTION: An analog computing circuit 11 calculates values Ix and Iy proportional to the inclination of a wave front from output values of 4 quadrant detectors 10 which detect a focus image of MLAs arrayed longitudinally and laterally in a two-dimensional lattice at equal internals. The output value Ix of the computing circuit 11 on the same line or the output value Iy of the computing circuit 11 on the same column is inputted into multiplexers (MPX) 12 on the same line or on the same column.

Abstract: PURPOSE:To improve luminous efficiency by composing an output of at least the following parts: a light transmission member which composes a back part of a vacuum envelope and is made of a high refractive index material whose refractive index is more than one, and a thin film output fluorescent screen which is disposed on an inner surface of this light transmission member, and by connecting an image sensor with the light transmission member when this tube is used. CONSTITUTION:An output surface is composed of the following parts: a light transmission member, e.g., a fiber plate 7 which composes a back part of a vacuum envelope 1 and is made of a high refractive index material whose refractive index is more than one, and a thin film output fluorescent screen 8 which is disposed on an inner surface of this fiber plate 7. This thin film output fluorescent screen 8 is a bulk phosphor layer or a flat phosphor layer which is formed by evaporation. A metal back thin film 9 is formed, for example, by Al evaporation on the inner surface (electron rush side) of the thin film output phosphor layer 8 in order to reflect luminous beams and utilize them effectively. When such a X-ray fluorescent multiplier is used, an image sensor e.g., an image pickup tube 11 having a photoconductive screen 10 is connected with the fiber plate 7, which serves as the light transmission member. Hence, the luminous beams can be guided effectively to the image sensor.
