    摘要： A method for sealing porous metals, which comprises applying powder of a eutectic alloy containing an element having a good diffusibility in a porous metal or powder of a mixture of metals capable of forming the eutectic alloy, to the surface of a porous metal member and heating the surface applied with the powder at a temperature higher than the eutectic temperature of the eutectic alloy to thereby cause the molten eutectic alloy to intrude into pores from the surface of the porous metal member, whereby the melting point of the molten alloy in the pores is promptly increased by diffusion of the element in the porous metal member to solidify the molten metal in the pores, sealing only pores present in the vicinity of the surface of the porous metal member.

    摘要： An optical modulation apparatus that performs optimum bias voltage control for optical modulation without using a pilot tone. A drive unit generates a drive signal by adding a bias voltage to an input data signal. A light modulation unit modulates input light output from a light source unit, in accordance with the drive signal, and outputs the results as optical signals. A forward monitoring unit monitors a forward signal of the light modulation unit and outputs the forward signal. A reverse monitoring unit monitors a reverse signal of the light modulation unit and outputs a reverse signal. A bias control unit controls the bias voltage so that a measured monitor ratio matches a target value of the ratio between the forward signal and the reverse signal, obtained when the operating point of the light modulation unit is in a predetermined position on its operation characteristic curve.
