Title: Preparation of semiconductor device
Inventor: NAKASHIMA HISAO
IPC: H01L21/76
Filed: 1978-10-09
Abstract: PURPOSE: To improve the density of integration, by preventing the bulging out of an insulating separation region in the lateral direction.  
     CONSTITUTION: SiO 2 2 and Si 3 N 4 3 are stacked on a surface of a Si monocrystal 1, and a groove 6 is manufactured by etching the films 3, 2 and the crystal 1 by CF 4  gas by using a resist mask. In this case, the peaks of Si 3 N 4  are formed. A SiO 2  film 4 is made up to the groove 6 by means of wet oxidation, and Si with approximate 10KeV energy is shot on the whole surface. The film 3 is removed by hot phossphoric acid, and a poly Si layer 5 is manufactured by means of a known selection growth method using SiCl 4 , thus completing a separation layer. Since there is no oxidation in the lateral direction according to this method, the width of a separation region is extremely narrowed, and an IC circuit can be compacted. And since the separation region and a surface of an electrical, active region become the same plane and birdheads are not built up on the separation region, disconnection can be prevented.

Title: X-ray image detection film and detection device
Inventor: NAKAISHI HIROYUKI
IPC: G03C1/00
Filed: 1994-06-06
Abstract: PURPOSE:To provide an X-ray image detection film having a high resolution and an expanded dynamic range by arraying one layer of the same type of atoms on the surface thereof and forming an X-ray image via the release of atoms in an X-ray irradiated section. CONSTITUTION:When an X-ray is irradiated in the directions of arrows 3, fluorine atoms in a section (a) exposed to the X-ray are released in the directions of arrows 4, among fluorine atom layers laid on the surface of a film 101. Furthermore, oxygen atoms are adsorbed, when fluorine atoms are released. On the other hand, fluorine atoms in a section (b) not exposed to the X-ray are not released. Thus, the X-ray image of a material as a detection object is formed on the film 101. This X-ray image has a very high resolution, and is even capable of attaining an atomic level of development. Also, as the elementary process of X-ray image detection is for the release of atoms or for atomic level, a dynamic range capable of maintaining sensitivity linearity can be expanded.

Title: Linearizer for non-monotonous phase distortion compensation
Inventor: NAKANO YUTAKA
IPC: H03F1/32
Filed: 1995-05-23
Abstract: PURPOSE: To compensate a phase characteristic of an amplifier changing non- monotonously with respect to an RF input level by adding a distortion generating route connecting an amplifier and a phase change device after a variable attenuator to a conventional linearizer and revising a fixed resistor attenuator before a linear amplifier into a variable attenuator. CONSTITUTION: Since amplifiers 3, 7, 10 all operates in the linear region when an RF input level is sufficiently low, the gain vectors of routes α, β in the linear and nonlinear amplifier route show prescribed values with respect to a change in the RF input level. On the other hand, as the RF level increases, since only the amplifier 7 operates in the linear region, the route α is decreased as the RF input level increases and the phase of the resultant vector C' is changed. When the RF input level is further increased, since the amplifier 10 operates also in the nonlinear region, the gain vectors of the routes α, β are both decreased and the phase of the resultant vector C" is further changed. Thus, a linearizer with a non-monotonous phase characteristic with respect to the RF input level change is realized.

Filed: 1990-05-14
Abstract: PURPOSE:To allow a nonmagnetic one-component developer layer to fly toward an electrostatic latent image carrier which is held with a gap to perform development and to obtain a high-quality image by using specified square wave bias and developer. CONSTITUTION:The one-component nonmagnetic developer which is electrostatically charged to have the same polarity as an electrostatic latent image on a developer carrier 2 is made close to the electrostatic latent image carrier 1 and the square wave bias is impressed on the carrier 2. The square wave bias has 300-1,500Hz frequency and is constituted of a 1st voltage part which has the same polarity as the electrostatically charged polarity of the developer and has the absolute value <=100V or which has the reverse polarity to the electrostatically charged polarity of the developer and a 2nd voltage part which has the same polarity as the electrostatically charged polarity of the developer and has the absolute value >=700V. Then, the square wave bias whose duty ratio is >=3:2 and where the temporal mean value of potential is biased to the reverse polarity to the electrostatically charged polarity of the developer in comparison with the case that the duty ratio is 1:1 is used. The developer whose load amount per unit mass is 5-20muC/g is used. Thus, the nonmagnetic developer layer flies in response to the intensity of the electric field of the electrostatic latent image, so that the high-quality image is obtained.

Consequently, when a color display, for example, hunter chromaticities (a) and (b) are plotted in this section figure, the hue angle and the chroma saturation can be read simply and accurately by utilizing radial lines and concentric circles. When the hue and the chroma saturation are obtained, two colors are indicated with lightness, hue, and chromasaturation, and therefore, the color difference quantity is indicated by the length in stereoscopic coordinates, and three components of the color difference, namely, the lightness difference, the chroma saturation difference, and the hue difference are indicated with length.

Abstract: PURPOSE:To increase easily the luminous intensity on the surface of an original by setting a light transmitting tool having an irradiation surface including a large input surface area opposite to the light source and a small area to be irradiated respectively between the light source and the scan reading point of the original. CONSTITUTION:A light transmitting tool 10 made of methacrylic resin is set between a fluorescent lamp light source 1 and a scan reading point 3 of an original 2. A hollow light input surface 11 equivalent to the projection area of a light emitting surface is provided to the tool 10 at the side of a light source 1 and opposite to the light emitting surface of the source 1. At the same time, an irradiation surface 12 having an extremely small area compared with the surface 11 is formed at the side of the point 3. Therefore an area of the surface to be irradiated at a place near the point 3 of the original 2 to be irradiated by the illumination light 16 is also small like the surface 12. At the same time, the light 16 is reflected by a white outer circumferential surface 17 of the tool 10 and simultaneously intensified. As a result, the luminous intensity is considerably increased on the original surface to be irradiated.
