Title: Display electron tube device
Inventor: TOBARI TSUTOMU
IPC: H01J29/46
Filed: 1986-11-14
Abstract: PURPOSE:To perform control of an electron beam quantity by a light for removing an influence on the other electrode of an electric signal for the control. CONSTITUTION:An electron tube 1 has a light-electron conversion means 3 in place of a negative electrode in a vacuum outer wall 2 made of glass. The light-electron conversion means 3 consists of a photo-electric surface 4 generating electrons in response to light, that is a photo-negative electrode and an electron multiplification part 5. Since this light-electron conversion means has the photo-negative electrode 4 in place of a thermal negative electrode of a general CRT for controlling the photo-negative electrode 4, it is possible to control an electron beam 6 by light without resorting to electric control by a grid. Thereby, a bad influence on the other electrode of a signal for controlling the electron beam 6 to be projected on a screen can be prevented.

IPC: G09F9/30
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent a breakage by static electricity at the time of production and to surely detect the disconnection and short-circuit of bus lines, by providing the panel with a protective wiring connected to capacitor electrodes and a high-resistance wiring connecting driving terminals and the protective wiring. SOLUTION: The capacitor electrodes 15 are formed above or below the driving terminals 24 and capacitors are formed between the capacitor electrodes 15 and the driving terminals 24. As a result, the failure of the bus lines by the static electricity may be averted in a production stage for the liquid crystal display panels. The capacitor electrodes 15 are connected to the protective wiring 13 and the respective bus lines 21 are connected to each other via the high-resistance wiring 33. If, therefore, the resistance value between adjacent terminals 25 for inspection is measured, the value adding the resistance value of the bus lines 21 and the resistance value of the high-resistance wiring 33 is attained.  If, on the other hand, the short-circuit arises between the adjacent bus lines 21, the resistance value between the adjacent terminals 25 for inspection diminishes by as much as at least the respective value-component of the high-resistance wiring 33 and the generation of the short-circuit is surely detected.

Abstract: PURPOSE:To decrease a current flowing from input output electrodes to a power supply electrode even when the electric potential of the power supply electrode at the time of operation is decreased down to ground level, by using an MOS transistor wherein a gate is formed on a selection oxide film, as a protecting circuit. CONSTITUTION:A polycrystalline silicon layer 4 is formed on a selection oxide film 3 for a protecting circuit on a semiconductor substrate 1 and a thin oxide film 2 adjacent to the film 3.

Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To improve the toughness of a connecting part by forming one notched part so that it is symmetrical to the other notched part when the end tab is rotated at a specific angle so as to be upside down and thereby efficiently welding a beam to a column. SOLUTION: A defect caused in the starting and ending points of a weld bead 36 is located outside in the width direction of a flange 3204; the weld bead formed in the notched part 6 spreads in a sector form on both sides of the bead in the longitudinal direction, encouraging toughness of a weld zone. The shape of the notched part 6 is formed symmetrically when the end tab 2 is reversed at an angle of 180 deg. so as to be upside down; therefore, the two end tabs 2 of the same shape can be used on the left and right of the flange 3204. In addition, since the end tab 2 is made of ceramic, it may be removed after welding and reused for other welding part, which is advantageous from point of cost reduction.  Further, in using the end tab 2, the striking direction to the column 30 is indicated, and whether it comes right or left of the beam 32 is displayed; hence, the arrangement operation is simplified.

Abstract: PROBLEM TO BE SOLVED: To prevent the plasma discharge of disks installed in a dummy region by maintaining the disk boards near their both ends at the grounding potential at the time of alternately arranging the plural positive and negative disk boards connected to a high-frequency power source in a reduced pressure atmosphere in a parallel state. SOLUTION: The disk boards 1, 2 which are flat planar and consist essentially of carbon are alternately arranged in parallel. Semiconductor wafers 3 are fixed to the pawls mounted at these boards in the direction perpendicular thereto and are installed in a reaction tube connected to a vacuum apparatus. The gases necessary for CVD reaction are passed to this tube. The high-frequency power source 5 is connected to the disk boards 1, 2 via the reaction tube and the prescribed high-frequency power is impressed thereon to function the boards as cathodes C and anodes A, thereby generating plasma and depositing CVD films on the semiconductor wafers 3. At this time, the disk boards near the ends of the disk boards 1, 2 are maintained at the grounding potential G to prevent the occurrence of the plasma reaction by glow discharge.  As a result, the deposition of the excess deposited films is prevented by the grounding potential G and the peeling of the deposits is suppressed.
