    摘要: A first inverter logic element, a second inverter logic element, and a third inverter logic element constitute a loop circuit, and a first transistor, a second transistor, and a third transistor are connected between an output of the third inverter logic element and an input of the first inverter logic element. An output signal is taken out from an output of the second inverter logic element, and an oscillation frequency is regulated by the first transistor, the second transistor and the third transistor. Consequently, in a voltage controlled oscillator of the present invention, the number of loop circuits and transistors for regulating the oscillation frequency can be decreased, so that a simulation process can be simplified and required characteristics of the oscillation frequency can be easily obtained.

    摘要: A printed circuit board includes a base insulating layer formed of a porous film. Conductor traces are formed on the base insulating layer formed of the porous film. A cover insulating layer is formed on the base insulating layer to cover the conductor traces. The porous film used as the base insulating layer has a reflectivity of not less than 50% for light of at least a part of wavelengths in a wavelength region from 400 nm to 800 nm.

    摘要: There is provided a pressure-sensitive adhesive composition for optical films. The composition can form a pressure-sensitive adhesive layer that can prevent light leakage caused by stress associated with dimensional change of a component such as an optical film, which include the pressure-sensitive adhesive layer that has reworkability such that it can be easily peeled from a component, and that has satisfactory processability such that it can be processed without pressure-sensitive adhesive stain or dropout, after it is formed on an optical film. A pressure-sensitive adhesive optical film produced using the composition is also provided. The pressure-sensitive adhesive composition includes a (meth)acrylic polymer including (a) 34 to 94% by weight of an alkyl (meth)acrylate monomer unit, (b) 5 to 35% by weight of an aromatic ring-containing (meth)acrylate monomer unit, and (c) 0.01 to 0.5% by weight of an amino group-containing (meth)acrylate monomer unit and further including (d) 0.05 to 3% by weight of a carboxyl group-containing (meth)acrylate monomer unit and/or (e) 0.05 to 2% by weight of a hydroxyl group-containing (meth)acrylate monomer unit and having a weight average molecular weight of 1,600,000 to 3,000,000 as determined by gel permeation chromatography; crosslinking agents including 0.01 to 5 parts by weight of an isocyanate crosslinking agent and 0.01 to 2 parts by weight of a silane coupling agent based on 100 parts by weight of the (meth)acrylic polymer.
