Abstract: PROBLEM TO BE SOLVED: To provide a high-frequency acceleration cavity with its high performance and low cost by lining a copper plate itself disposed on an inner face of a cavity body fabricated of a high-strength metal material by thermally isometric pressurization of canless as a pressure boundary. SOLUTION: Without thermally isometric pressurization of a cavity body 1 and an end plate 2 separately, a beam port 3 and an input port 4 are sealed with a lining plate 5, an end plate 2, a cavity body 1, and a sealing weld part 8, the whole is assembled by an assembling welding part 10, and at the same time thermal isometric pressurization is applied, thereby making it possible to perform lining simultaneously with an inner face of the cavity body 1. Thus, in a process technically and timely facilitated more than conventionally, faults due to action of thermally isometric pressurization process are eliminated, and a high-frequency acceleration cavity having its inner face better characterized by re-crystallization or the like can be obtained. As a result, fabrication work is facilitated, and cost reduction is ensured.

Abstract: PROBLEM TO BE SOLVED: To provide a display constituted so that the fatigue of eyes is prevented by simple constitution by projecting a displayed picture as a virtual image and always changing the position of the projected virtual image. SOLUTION: The picture displayed on a liquid crystal panel 1 is projected as the virtual image by a lens 2. The panel 1 and a backlight 4 are provided on a direct moving guiding mechanism 5 and move back and forth in an optical axis direction by directly moving the mechanism 5. A rear position sensor 7 and a front position sensor 8 detect the panel 1 and inform a CPU 10 of the existence of the panel 1. The sensors 7 and 8 are moved while an observer observes the picture, and adjusted to a position taken just before the picture becomes blurred and is vanished.  Since the position of the picture to be observed is changed at speed to such an extent that the observer is not conscious of it, the observer is prevented from keeping observing one point even when the observation is kept for a long time, whereby the fatigue given to the eyes is reduced in comparison with the case that the position is not changed.
