Filed: 1988-08-10
Abstract: PURPOSE:To improve a current amplification factor at a low collector current region by a method wherein an emitter-base junction interface is formed into a structure wherein the interface is moved nearer the side of a base from a heterojunction interface. CONSTITUTION:An n<+> collector contact 12, an n<-> collector 13, a p<+> base 14 and an insulating film 16 are formed on a substrate 11 by a normal method and thereafter, an emitter electrode window is opened on the film 16 and a phosphorosilicate glass film (a PSG film) 20 is grown. Then, a heat treatment is performed to diffuse an impurity and after an n-type emitter 10 is formed, the film 20 is removed. Subsequently, an N-type hydrogenerated microcrystal Si film is grown to form an n-type muc-Si:H emitter 15 and after that, electrodes 17, 18 and 19 are formed to obtain a heterojunction bipolar transistor. According to such a way, the crystallizability of an emitter-base junction interface is improved, and therefore the recombination current of carriers is reduced to increase the current amplification factor.

Title: Spot position detection type holographic storage device
Inventor: YAGI IKUTAKE
IPC: G03H1/26
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to use a recording medium as a high speed and large capacity memory by focusing a reference beam through the use of a lens and adopting a system to shift the recording medium. SOLUTION: A beam of transmitting light without change in the direction is used as a reference beam 9, and a component of the beam changed in the direction is used as an object beam 10. A plane wave changed in the direction and a plane wave unchanged in the direction are focused through a lens 5. The object beam 10 and the reference beam 9 interfere with each other in a recording medium 4 and are able to form an interactive region 11, in which interference fringes formed by the object beam 10 and the reference beam 9 can be recorded. When a part, where the interference fringes are recorded, is irradiated with the reference beam 9, diffracted light is obtained when a relative position of the reference beam 9 to the recording medium 4 is the same at a time of recording.  Thus, a single time emission of the reference beam 9 permits readout of position information, namely, multiple bit information by arranging an optical position detecting device(PSD) 6 and detecting a position where the diffracted light is focused.

Abstract: PURPOSE:To obtain a high-quality image with high density which is excellent in the reproducibility of thin line by positioning the center of the developing main pole of a magnet in a developing roller on an upstream side on an upper-stream side than a line which passes the center of the developing roller on the upstream side and the center of an electrostatic latent image carrier. CONSTITUTION:The lines I and II which pass the centers O1 and O2 of developing sleeves 10 and the center OP of a photosensitive drum P are respectively set as references and angles made by the lines III and IV which pass the centers O1 and O2 and the center of the developing main pole to the lines I and II are taken as theta1 and theta2. The developing main pole is arranged, for example, so that theta1 may be a positive value and theta2 may be the value of about + or -0 deg.. Even if individual variance occurs in the conveyance quantity of developer because of the error caused in production, development is always stably performed without receiving the drastic effect of the variance. Since developing units 1 and 2 do not have adverse effect on each other, the separation of function is accomplished by securing the reproducibility of image density in the developing unit 1 on the upstream side and that of thin line in the developing unit 2 on downstream side. Thus, the reproducibility of image density and the reproducibility of thin line can be made compatible.
