Title: Linear accelerator
Inventor: KIMURA KATSUICHI
IPC: H05H9/00
Filed: 1988-02-23
Abstract: PURPOSE:To obtain a charged particle beam with a narrow energy interval by a miniaturized linear accelerator by cascade-connecting standing-wave accelerating means and progressive-wave accelerating means mixedly. CONSTITUTION:Charged particles emitted from an electron gun 1 are fed into a standing-wave accelerating tube 61, and bunching-accelerated therein by a high frequency electric field supplied from a microwave source 91 via a circulator 81 and a transmission circuit 71. The bubching-acceleration in the standing- wave accelerating tube 61 is effected by a high strength electric field, so that a charged particle beam bunched into a narrow phase interval and having a narrow energy interval is obtained. This beam with the narrow phase interval and the narrow energy interval is fed into a progressive-wave accelerating tube 21 of the next stage and accelerated therein without undergoing a large influence of radial electric field. The charged particles are thus accelerated by multiple stages of standing-wave accelerating tubes 61-6k and progressive- accelerating tubes 21-2n arranged alternately, for producing a high energy output. The accelerator can be miniaturized and the charged particle beam with a narrow energy interval can be obtained accordingly.

Abstract: PURPOSE:To block or drastically decrease the DC component to deteriorate a liquid crystal by flowing into a liquid crystal cell and to prevent the degradation of display image quality by coating the surfaces of signal lines and drain wirings consisting of Al with an insulating alumina film. CONSTITUTION:The thin conductive films 22 and signal lines 12 for connecting picture element electrodes 14 and the drains of insulated gate type transistors (TRs) on an active substrate 2 of an active type liquid crystal panel disposed with the insulated gate TRs as switching elements to each of the picture elements are formed of the same material Al. An anodic oxidation stage for selectively insulating only the signal lines 12 and the drain wirings 22 is introduced to this active substrate 2 to selectively form Al2O3 (alumina) films on the signal lines 12 and the drain wirings 22. Connecting lines 23 are cut if the active substrate 2 is cut along cutting lines 33 after the end of the anodic oxidation. The active substrate 2 is thus completed. The DC component flowing into the liquid crystal cell is blocked or drastically decreased by this active substrate 2.

Abstract: PURPOSE:To improve fault analytical capacity by detecting a signal accompanied by a light absorbing current generating in a sample device through the irradiation of a laser beam indicating a light absorbing current image based on a signal accompanied by the detected light absorbing current. CONSTITUTION:A light absorbing current image is observed on an oscilloscope 36 under varying action conditions on a sample device 11 by changing input conditions against the sample device 11 in an input signal generation circuit 41.

A sound image is indicated on the oscilloscope 24 and therefore, it is possible to observe a sound image and at the same time, observe a light absorbing current image. Thus the physical defect of the sample device 11 can be detected as well as the malfunction or fault of electrical characteristics.
