摘要： The present invention is a method of solidifying sulfur component being the cause of “SOx poisoning” by use of a sulfur solidifier. The solidifier includes a metal element having a function of oxidizing the sulfur component and a basic metal element. And the solidifier solidifies sulfur component before exhaust gas flows into an NOx-occluding reduction-type exhaust purifying catalyst located on an exhaust path. Since the foregoing sulfur solidifier includes the above metal element and the basic metal element, it can effectively solidify the sulfur component which are the cause of the SOx poisoning, and ensure improvement in purification performance.

摘要： A noble metal composite colloid composed of a plurality of noble metals is constructed to be loaded on a porous oxide support. The noble metals are loaded in particles which are larger than the conventional grains in the atomic state. Thus, vapor pressure decreases and volatile components, such as PtO2, are suppressed from dislocation or diffusion. In addition, affinity of the noble metals with the support is improved, and are suppressed from moving on the support. Thus, nobel metal grain growth is suppressed, decreases in catalytic activity is minimized and durability is improved.

摘要： An optical assembly structure includes, a semiconductor element generating a large amount of heat and a high impedance optical element which are to be mounted, with low optical loss on the same semiconductor substrate which has an optical waveguide formed thereon.The element generating a large amount of heat is mounted on a terrace of the semiconductor substrate directly or through an insulating layer having a thickness of submicron order, while the high impedance element is mounted in a groove which is etched into the semiconductor substrate to such an extent that the optical axis of the high impedance element mates with the optical axis of the optical waveguide layer formed on a recess in the semiconductor substrate. The optical axes can be adjusted independently for the respective elements. Alternatively, with a potential on the semiconductor substrate set equal to a supply voltage or a ground potential, a crystal substrate for a forward biased heat generating element is given the polarity opposite to that of a crystal substrate for a reverse biased element which may imply a problem of stray capacitance.

摘要： An optical module including a transimpedance amplifier capable of realizing a high-speed and high-quality receiving operation is provided. A transimpedance amplifier includes: a pre-amplifier using a single-end current signal as an input and converting the single-end current signal to a single-end voltage signal; an automatic decision threshold control detecting a center electric potential of the single-end voltage signal serving as an output of the pre-amplifier; a post-amplifier differentiating and amplifying the single-end voltage signal of the output of the pre-amplifier; and a power circuit supplying power to the pre-amplifier. Particularly, in accordance with an input voltage signal or an output voltage signal of the pre-amplifier, the power circuit outputs a varied current that flows to a supply terminal of the pre-amplifier and a varied current having a phase opposite to that of the varied current. Thus, the power supply current change is cancelled out.

摘要： The present invention provides a highly reliable ridge-waveguide semiconductor laser diode and an optical module. The p-side electrode of the ridge-waveguide laser diode has a first conductor layer region and a second conductor layer region formed on the first conductor layer region. At least one of facets of the second conductor layer region is recessed inward from a reflection facet. Thus, the ridge-waveguide semiconductor laser diode has a structure in which strain which is caused by the electrode stress to be applied on the diode facet is reduced and the saturable absorption does not occur. The ridge-waveguide semiconductor laser diode thus obtained is highly reliable, and the optical module using the same is remarkably high in reliability.
