Title: Color picture tube
Inventor: KIDA KINJI
IPC: H01J29/07
Filed: 1986-02-13
Abstract: PURPOSE:To hold down mislanding all over the effective faceplate, by forming an electron absorbing layer on the main surface of the electron gun side of the shadow mask of a color picture tube. CONSTITUTION:An electron absorbing layer 31 is formed on the center side wall surface 17a of a transmitting hole 27 of a shadow mask 17, and a part of the layer is located on the main surface 17b of the side of the shadow mask where electron beams collide. Thereby, when electron beams are deflection- scanned, the layer is negatively charged corresponding to the density of the electron beams. The negative electric charge on the center side wall surface of the transmitting hole 27 deflects an electron beam 15C as shown by the solid line 15a. Therefore, the landing spot 42a of an electron beam which is apt to move in a pipe axis 47 direction more than a prescribed landing spot 42 owing to a doming phenomenon is counterbalancely operated to return to the landing spot 42 again. Thus, even if the doming phenomenon is brought about, the mislanding of electron beams can be held down and reduced.

IPC: H01L29/78
Filed: 1989-02-06
Abstract: PURPOSE:To eliminate a need for treatment used to leave an electrode part and a source drain part and to reduce a sheet resistance in a source region and a drain region by a method wherein the source electrode part and the drain electrode part are once removed completely in a formation process of a gate electrode and, after that, the source electrode part and the drain electrode part are formed again by a polycrystalline semiconductor thin film. CONSTITUTION:A polycide structure is formed of polysilicon 5 and tungsten silicide 6; after that, a gate region is formed by an ordinary photoresist process and an ECR dry etching process; a silicon nitride film 7 for side wall use is deposited on the whole surface by a CVD operation. Then, a silicon oxide film 2 is removed down to a depth of about 200nm; after that, titanium silicide 8 for source and drain use is deposited on the whole surface; the whole surface of a substrate is etched back and flattened; a gate electrode part is isolated from a source electrode part and a drain electrode part. Thereby, a dry etching operation to uniformly leave the source electrode part and the drain electrode part is not required; a film thickness of the source part and the drain part is increased; in addition, since a low-resistance material is used, sheet resistance value is reduced.

Filed: 1989-02-07
Abstract: PURPOSE:To completely achieve a side erasing and interimage erasing function and an original size detecting function by making a diffraction grating surface formed on the surface of a metal plate whose reflectance is high an original cover surface. CONSTITUTION:The tooth-shaped diffraction grating surface 50 is provided on the original cover surface side corresponding to the lower surface of the original cover plate 5.

Title: Semiconductor device
Inventor: KADOWAKI MASAHIKO
IPC: H01L27/14
Filed: 1984-02-20
Abstract: PURPOSE:To eliminate poor appearance due to the squeeze-out of a sealant at the container-cap sealing part, and to improve the reliability by increase in sealing strength by a method wherein the sealing surface of the cap is chamfered. CONSTITUTION:A glass cap 3' provided with the chamfered part 3e in the sealing surface of a ceramic frame 3c is used. The chamfering dimension is determined according to the amount of used solder and the size of load. Thereby, the container and the cap 3' come into welding at the parallel plane sections of the sealing surfaces with each other; however, the squeezed solder is trapped in the space formed by the chamfered part 3e of the cap 3 and the sealing surface of the container. In other words, the amount of solder can be restricted by the amount of formed space; therefore, the load at the time of sealing and the margin of the amount of solder and the like increase, thus enabling solder sealing with good yield. Further, since the sealing surface substantially increases by applying a metallized layer 3d to the chamfered surface, the sealing strength is enhanced and the reliability improves.

Title: Color picture tube device
Inventor: KOSHIGOE SHINPEI
IPC: H01J29/48
Filed: 1986-02-14
Abstract: PURPOSE:To obtain a clear and sharp picture while deflecting an electron beam in the horizontal scanning direction by applying different kinds of voltage between two specifically-shaped electrodes of a color picture tube. CONSTITUTION:The negative electrodes KR, KG, KB and the first-sixth grids 10, 20, 30, 40, 50, 60 are arranged in the electron beam emitting direction in this order with intervals. In the grid 40, electrode members 41 and 42, in which a plate-shaped electrode is provided with a cylindrical projection 43, are opposedly arranged. The surface formed by the tip of said cylindrical projection 43 is non-parallel to the vertical plane to a tube axis while being the inclined surface practically parallel to the horizontal scanning direction. When higher voltage is impressed on the electrode member 41 than on the electrode member 42, an electron beam is deflected to the direction B. Further, when higher voltage is impressed on the electrode member 42 than on the electrode member 41, the electron beam B is deflected to the direction A. The direction and angle of deflection are all the same as to the central beam and both side beams. Thereby, halo of the side beams can be remarkably reduced so as to obtain a clear and sharp picture.

Abstract: PURPOSE:To obtain an X-ray generation device having no air leak part while having little local and timing change of temperature by getting rid of a vacuum sealed part surrounding an axis of rotation while spraying a cooling medium on a target to be cooled. CONSTITUTION:An electron gun 2 radiating electron rays is fixed to a vacuum wall 1 rotating by an external driving force. Thereby a vacuum sealed part causing air leak into a vacuum is removed. Electrons radiated from the electron gun 2 are downwardly deflected as shown by the arrows (a) and (b) due to a magnetic field vertically applied in the direction of electron radiation to be incident to a target 5. X-rays emitted from the target 5 are taken out outside an X-ray generator through a ring-shaped window 6 mounted on the vacuum wall 1. The target 5 to be heated by the electron radiation gets rid of heat by a cooling medium jetted from a nozzle 10. Thereby, a rate of temperature rise due to the electron ray radiation can be made smaller.

Abstract: PROBLEM TO BE SOLVED: To change the frequency of a clock signal and to improve the total processing speed of a microprocessor by using a clock control circuit which changes the frequency of a clock to be supplied to each pipeline stage based on the time information held by each pipeline holding means. SOLUTION: A clock control circuit 353 changes the frequency of a clock signal 354 based on the time information held in the time information fields 321a, 331a and 341a of stages E, M and W respectively.
