Inventor: NAKAMURA KOJI
IPC: H01J29/02
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce luminescence variations, even if a shadow grill resonates when an impact is impressed. SOLUTION: Each pair of pins 21a, 21b and 23a, 23b are installed side by side on each side inside a glass panel 1 corresponding to the respective upper and lower edges of a rectangular phosphor screen by separating them from each other by a predetermined distance generally at its central position, in order to suspend and support a shadow mask 7 embedded in the glass panel 1 used in a color picture tube. The shadow mask 7 is fixed firmly in the panel 1 and can thereby shift its resonant frequency to the higher side with respect to the vibrations transmitted from the outside.

Title: Manufacture of semiconductor element
Inventor: HAYASHI SAIKI
IPC: H01L21/28
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To improve the topology of a semiconductor device so as to improve the yield of the manufacturing process of the device and the reliability of the element by crystallizing amorphous structures in lower and upper tungsten silicide films and, at the same time, forming oxides films on the surfaces of crystal grain boundaries in the upper tungsten silicide film. SOLUTION: A lower amorphous tungsten silicide film 14 is formed on a polycrystalline silicon film 13 and an upper amorphous tungsten silicide film 15 containing small fragments is formed on the film 14. Then the films 14 and 15 are crystallized by heat-treating the films 14 and 15 in an oxygen atmosphere. During the crystallizing process, oxygen permeates gaps between the fragments in the film 15 and thinly oxidizes the surfaces of crystallized crystal grains, resulting in thin oxide films 16 formed on the surfaces of the crystal grains.

Filed: 1983-09-17
Abstract: PURPOSE:To manufacture an alumina substrate having single crystal surface layer and uniform quality, at a low cost, by forming an amorphous or polycrystalline thin film on the surface of an alumina substrate having a duplex structure composed of plural islands. CONSTITUTION:A formed alumina article made of powdery raw material and giving a duplex structure by the main baking process, is heated preliminarily at a temperature lower than that of the main baking by 200-400 deg.C.

Title: Microwave amplifier
Inventor: HORI SHIGEKAZU
IPC: H01P5/02
Filed: 1981-10-27
Abstract: PURPOSE:To permit reduction in area of a matching circuit pattern thereby to allow a microwave amplifier to be more compact, by a method wherein an electrode is provided on the  lower surface of a non-conductive substrate, and a conductive film is partially provided on the  upper surface thereof so as to connect with the electrode, and moreover, a dielectric film and  a microstrip line are piled on the conductive film. CONSTITUTION:An electrode 52 is formed on the lower surface of a dielectric substrate 51, and  strip-like metal films 54 are formed on some parts of the upper surface thereof, each of which  films 54 is connected at both ends thereof to the electrode 52 through metal films 53 on side  surfaces of the substrate, and are covered with a dielectric film 55, on which a microstrip line  56 is formed. If the thickness HD of the film 55 is made sufficiently smaller than the thickness  H of the substrate 51, the characteristic impedance ZL of the low impedance part is determined by WL/HD, where WL is the line width of the film 56, since the films 54 and the electrode 52 have the same potential. Because HD is small, if WL is made small, ZL can be made  sufficiently small, so that it is possible to reduce the line length lL while obtaining a necessary capacity C. In other words, if strip-like metal films 61 are provided on a substrate 13 as predetermined, then, it is possible to reduce the pattern area of the low impedance part. Accordingly, the matching circuit substrates 13, 14 reduce in size to allow the microwave amplifier to be more compact.

Filed: 1988-07-12
Abstract: PURPOSE:To perform vector operation processing at a high speed without enlarging the logical scale even in the case of a large vector stride value by providing a buffer storage where only vector elements for vector operation processing are registered. CONSTITUTION:A vector operation control part is provided with vector buffers 24 and 26 operated independently of the buffer storage device used by an execution control part, and vector elements are registered in these vector buffers 24 and 26 through data registers 23 and 25.

These vector elements are read out in the stage of operation processing to execute the vector operation processing, and next vector elements are read out of the main storage device in parallel with this processing and are registered in buffers 24 and 26. Thus, the operation processing of vector elements is performed at a high speed without enlarging the logical scale even in the case of a large vector stride value.

Title: Sheet transfer device
Inventor: IWASAKI SHINICHI
IPC: B65H5/22
Filed: 1985-08-05
Abstract: PURPOSE:To prevent a picture forming member from leading end folding and jam due to the defective advance into a fixing roller section by reducing the opening area of each air intake port successively as it recedes from the position regulating side. CONSTITUTION:When transferable materials having the largest size covering the full width of a belt-like transfer device are transferred, they act effectively on all air intake ports 37, 39, 40 through holes 30 provided in the belt so that they are held by transfer bodies 31, 32, 33 with satisfactory close adhesion. Also, in the case of transferable materials having the size smaller than said ones, since the position of the side faces of the transferable material are regulated, the transferable materials are not mounted on the upper side belt 32 or 33. However, since the opening area of the air intake port beneath the belt 32 or 33 is smaller, air intake amount is small so that the whole attraction is not so much affected and the transferable materials are transferred as they are closely attached to the belt 32 or 32.
