摘要： This catalyst support aims to improve heat resistant and durability by highly dispersing an NO.sub.x storage component. This catalyst support is produced by mixing a solution of a chemical compound including at least one element of alkali metals, alkaline-earth metals, and rare-earth elements with a solution of oxide sol of at least one metal of group IIIb, group IVa, and group IVb in the periodic table to prepare a mixed sol solution, forming the mixed sol solution into gel, and drying and calcining the gel. The obtained catalyst support is amorphous and attains a high specific surface area even when calcined at elevated temperatures, so that the catalyst support is superior in heat resistance.

摘要： An optical fiber is held in a ferrule, and then the ferrule is located in a positioning groove formed in a substrate, thereby aligning the optical fiber with an optical device bonded to a surface of the substrate. Then, a lid is placed on the substrate in such a manner that the ferrule is located in a positioning groove formed in the lid and that the optical device is received in a cavity formed in the lid. The ferrule is thus held between the two grooves, and in this condition a resin is filled in the two grooves, thereby retaining the ferrule. Then, the lid is sealingly secured to the substrate. After these parts are thus assembled together, this assembly is put in dies, and then a package is molded.

摘要： The present invention relates to a semiconductor laser which oscillates in a single longitudinal mode and with a low threshold current and which exhibits a good mode stability against reflected light, and provides a structure of a distributed feedback semiconductor laser with modulation for a gain. The structure is such that gain producing regions are periodically arranged and that a substance transparent to laser radiation is buried between the regions. A layer including the gain regions is formed of a superlattice layer, and an impurity is diffused or implanted into periodic positions of the layer, whereby the transparent regions and the gain regions with little lattice damages can be readily formed.

摘要： A buried-heterostructure semiconductor laser including a mesa-shaped optical confinement region having an active layer and a clad layer and disposed on a semiconductor substrate; a burying layer burying both side surfaces of the region; and at least one p-n junction so formed inside the burying layer in parallel to the active layer as to be brought under the reversely biased state during the operation of the laser; wherein surface protection semiconductor layers are formed on the mesa-shaped optical confinement region and on the burying layer, respectively, for protecting the semiconductor assembly in the arrangement such that these surface protection semiconductor layers do not come into direct contact with each other. Even if the forbidden band gas of these surface protection semiconductor layers are relatively small, it is possible to realize a semiconductor laser having an extremely small leakage current and reduced variance of threshold current values, while protecting the surface of the multi-layer semiconductor layers.

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.

摘要： A server system has servers that can be operated through switching as a primary system and a standby system, and a shared disk unit for storing data accessed by the servers. Each of the servers has a driver that acquires information on a configuration inside the shared disk unit after starting of the system. The driver sets the shared disk unit in an active state in which an access request can be sent to the shared disk unit. Access control determines whether the access request issued by an application should be sent on the basis of a management table indicating inhibited types of access requests for each access destination. The access control sends the access request to the driver when the access request is not inhibited for an access destination of the access request. By this arrangement, hot standby switching processing can be performed at high speed.
