A plurality of vias is disposed side by side on a multilayer board. A first via which is one of the vias disposed at one outer portion is electrically connected to a first outgoing line provided on the multilayer board. A second via at the other outer portion is electrically connected to a second outgoing line provided on the multilayer board. A plurality of the vias is connected to a first fixed potential layer (a ground layer, for example) of the multilayer board. At least one second fixed potential layer is provided, with a plurality of the vias through a clearance and having the same potential as that of the first fixed potential layer, as an inner layer of the multilayer board between the first and second outgoing lines and the fixed potential layer. Therefore, a BPF whose rate of occupied area is low is formed on the multilayer board without additional production processes.

There are provided a turbine rotor having suitable strength and toughness without causing soaring manufacturing costs and prolonged manufacturing time, and a manufacturing method of the turbine rotor. In a turbine rotor constructed by welding a rotor member for high temperature made of high Cr steel, and a rotor member for low temperature made of low Cr steel, the high temperature rotor member is formed from high Cr steel of which the nitrogen content is 0.02% or higher by mass %, and a filler material which welds the high temperature rotor member and the low temperature rotor member together is a 9% Cr-based filler material of which the nitrogen content is 0.025% or lower by mass %.
摘要:
According to the present invention, whether recoding pits are larger or smaller than diffraction limit is determined. Then, a signal process suitable for processing of the recording pits larger than the diffraction limit and a signal process suitable for processing of the recording pits smaller than diffraction limit are divided to divisionally perform equalizer processing. The respective signals subjected to the divisional processing are synthesized to obtain a processed output signal. A reproduction signal with reduced impact of intersymbol interference is thus obtained.
