Abstract: A sheet processing method including irradiating a transparent conductive layer covered with a transparent sheet with a pulsed laser beam such that the pulsed laser beam is applied to a portion of the transparent conductive layer through the transparent sheet, and that the portion irradiated has an insulating property. The pulsed laser beam has a top-hat intensity distribution and has a transmittance through the transparent sheet being higher than a transmittance through the transparent conductive layer.

Abstract: A light control sheet includes: a laminate having a light control layer containing a liquid crystal compound and a dichroic dye; and a first protective layer and a second protective layer that are disposed to the laminate and absorb light in an absorption wavelength range including an ultraviolet region. The laminate in an opaque state has a chromaticity a* of −15 to 15 and a chromaticity b* of −16 to 15 in a CIE1976 (L*a*b*) color system in accordance with JIS-Z-8781-4. The smallest value of the absorption wavelength range is 360 nm or less, and the upper limit of the absorption wavelength range is 410 nm to 430 nm within the visible region. The protective layers have a chromaticity a* of −10 to 0 and a chromaticity b* of 0 to 15 in a CIE1976 (L*a*b*) color system in accordance with JIS-Z-8781-4.

Abstract: A circuit board having excellent reliability of connection between layers while being capable of achieving a compact and low-profile electronic device. In the circuit board has an LC circuit built therein with the use of a glass core having a through hole, a conductor layer formed in the through hole is connected to a wiring pattern formed on one surface of the glass core, and connected to a wiring pattern formed on the other surface of the glass core, with the conduction layer projected from the surface of the glass core. Thus, the area of contact between the conduction layer and the through hole is increased, thus making it possible to prevent the reliability of connection between layers in the through hole from being decreased, even when the glass core is reduced in thickness for achieving a low-profile device.
