To provide a capacitive touch switch capable of improving ununiformity of design and improving appearance relating to design or decorativeness. A capacitive touch switchincludes a glass substrate, a sensor portion formed at a side of an opposite surface opposite to a touch surface of the glass substrate. The sensor portion includes a center portion A of a wire attached portionto a flexible printed circuit, and a connection portion C connected to the wire network B. In the connection portion C, an opening rate in a capacitive touch switch panel is increased by setting an electrode pattern width to be thinner from the wire attached portion A toward the wire network B.

Capacitive touch switch

Provided is a capacitive touch switch panel on which it is possible to form a transparent sensor electrode having high quality design shape and reduced reflection of visible light, and which moreover has excellent appearance and ample environmental resistance. This capacitive touch switch panelis provided with a glass substrate, and with a sensor partformed on this glass substrate. The sensor parthas a sensor electrode, this sensor electrodecomprising an Al thin film formed by sputtering or vacuum deposition into a switch configuration on the glass substrateat the opposite surface sidefrom a touch surface, the sensor parthaving an intermediate layer between the glass substrateand at least a portion of the Al thin film. This intermediate layer comprises a thin film that includes at least one metal selected from Cr, Mo, and W.

Capacitive touch switch panel

A vacuum tube includes a filament and two pairs of a grid and an anode. The filament is tensioned linearly and emits thermoelectrons. Both of the anodes are formed on a same face on a planar substrate. The filament is arranged parallel to the planar substrate at a position facing both of the anodes. Each of the grids is arranged, such that the grid faces the anode of a same pair at a first predetermined distance from the anode and has a second predetermined distance from the filament, between the anode and the filament. The vacuum tube further includes an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs.

Vacuum tube

An object of the present invention is to provide a vacuum tube with a structure close to that of an inexpensive and easily available vacuum fluorescent display which easily operates as an analog amplifier. A vacuum tube subject to the present invention comprises: a filament which is tensioned linearly and emits thermoelectrons, an anode arranged parallel to the filament, and a grid arranged between the filament and the anode such that the grid faces the anode. The present invention is characterized in that a distance between the filament and the grid is between 0.2 mm and 0.6 mm, including 0.2 mm and 0.6 mm.
