Title: Shadow mask and manufacture thereof
Inventor: SAKURAI KOICHI
IPC: H01J29/07
Filed: 1986-12-11
Abstract: PURPOSE:To obtain a screen which is flat and easy to see and unify the brightness on the screen by making the center lines of through apertures of a shadow mask material equal to the incident directions of the image electron beams entering the through apertures. CONSTITUTION:Energy beams such as electron beams or laser beams are radiated to bore through apertures 6 on a shadow mask material 1 so that they enter in the same direction as the incident directions of image electron beams, then the incident direction of the image electron beams 7 becomes the same as the center lines of the through apertures 6. Therefore, electrons entering the fluorescent screen 11 of a cathode-ray tube are increased, thus the screen can be made brighter. In addition, cross section areas of electron beams passing the through apertures at the end section of the screen are made larger than those in the past. Accordingly, high resolution and uniform brightness can be obtained on the flat screen.

IPC: H02M7/48
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To stabilize the feedback control of a converter control means by changing the gain in feedback control of the converter control means, based on the DC output voltage or command voltage. SOLUTION: The gain i in a current control loop is changed in inverse proportion to actually detected DC output voltage by a gain changing means 30. Then, in the case of raising or lowering the DC output voltage outputted from a PWM converter device, the gain is changed to a proper value, corresponding to this. Hereby, even in the case of controlling the DC output voltage Vdc, the feedback control of a converter control circuit becomes fully stable one.

Abstract: PURPOSE:To prevent positional displacement approximately extending over the whole region of a wafer, and to transfer a pattern with excellent uniformity by passing only one part of X-rays emitted and radiated from an X-ray source, determining the direction thereof and exposing a mask and the wafer by using the X-rays. CONSTITUTION:When a wafer is exposed through a mask by X-rays, an aperture 8 through which only one part of X-rays emitted and radiated from an X-ray source such as an electron-beam excitation type X-ray source is passed is formed, and arranged at that time so that a passing hole 8a through which X-rays pass is positioned on the center line of the X-ray source 1. One part of X-rays emanated and radiated from the X-ray source 1 passes through the passing hole 8a for the aperture 8. The passing X-rays are not formed in an emitting shape but in the fixed direction. The regions of the mask and the wafer left as they are mutually held in a parallel with the passing X-rays relatively move. Accordingly, the whole region of the wafer can be exposed with excellent uniformity, and a pattern can be transferred without approximately generating positional displacement extending over the whole region of the wafer.
