Abstract: A touch panel is formed by laminating: a glass substrate having a touch surface; an X-axis sensor unit having parallel patterns, each of which having diamond-shaped X-axis lattices 10A and 10B aligned in an X-axis direction; an Y-axis sensor unit having parallel patterns each of which having Y-axis lattices 14A and 14B aligned in a Y-axis direction; and an insulation layer arranged between the X-axis sensor unit and the Y-axis sensor unit. The X-axis lattices and the Y-axis lattices are not overlapped when seen from a side of the touch surface. A gap 17 is formed between a frame line 10a of the X-axis lattice and a frame line 14a of the Y-axis lattice. A protrusion part 12 extended parallel to a lattice side of a fine lattice from the frame line 10a of the X-axis lattices 10A and 10B is arranged in the gap 17.

Abstract: An analog amplification vacuum tube of the present invention suppresses influences of filament vibration on amplification characteristics. The analog amplification vacuum tube of the present invention is provided with a filament, an anode, a grid and a vibration-proof part. The filament is tensioned linearly and emits thermal electrons. The anode is disposed parallel to the filament. The grid is disposed between the filament and the anode so as to face the anode. The vibration-proof part includes a thin film usable in a vacuum environment and the thin film comes into contact with part of the filament.
