In a process for manufacturing a semiconductor integrated circuit device having a MISFET, in order that a shallow junction between the source/drain of the MISFET and a semiconductor substrate may be realized by reducing the number of heat treatment steps, all conductive films to be deposited on the semiconductor substrate are deposited at a temperature of 500° C. or lower at a step after the MISFET has been formed. Moreover, all insulating films to be deposited over the semiconductor substrate are deposited at a temperature of 500° C. or lower at a step after the MISFET has been formed.

Method of manufacturing a thin film magnetic head which can exhibit a high-performance head characteristic without complicating the manufacturing procedure. A coil connection is integrated into one body and constituted part of the thin film coil. A connection middle pattern is provided on the coil connection at the time of forming a pole tip so that the position of the upper surface of the connection middle pattern becomes higher than that of the top pole tip. After the whole portion is covered by an insulating film, the connection middle pattern also can be exposed by polishing the surface of the insulating film until the top pole tip is exposed. Therefore, unlike the case where no connection middle pattern is provided, it is not necessary to form an opening by partially removing part of the insulating film. As a result, the number of manufacturing steps can be reduced.

A sodium-based dechlorinating agent is added to a flue gas; hydrogen chloride contained in this flue gas is removed as residue of dechlorination; the thus removed residue of dechlorination is dissolved by adding water; water-insoluble constituents are separated from the resulting aqueous solution; and after adjusting pH of the aqueous solution remaining after separation of the water-insoluble constituents, mercury, dioxin, and the like are removed and discharged. The sodium-based dechlorinating agent is mixed with a hydrophilic anti-caking agent, with an angle of repose of 40° or more, a dispersibility of less than 50, and a floodability index value of less than 90. This permits inhibition of occurrence of a pressure drop and leakage in the filter cloth of the dust collector.

An adaptive control apparatus that adaptively controls directivity of an array antenna is disclosed. The adaptive control apparatus that can be used by a radio apparatus and a receiver includes a setting unit configured to set up parameters such as the distance between the radio apparatus and the receiver that receives a radio frequency signal transmitted by the radio apparatus, the relative moving speed, and the moving direction of the receiver in reference to the radio apparatus. The adaptive control apparatus further includes an evaluating unit configured to evaluate how much received power at the receiver or the radio apparatus changes after a predetermined period, and a weight control unit configured to adjust two or more weighting factors about two or more antenna elements that constitute the array antenna. The directivity of the array antenna is controlled such that the amount of change of the received power is kept within fixed limits independent of the distance between the receiver and the radio apparatus.

A passively modelocked fiber laser includes a laser diode generating laser energy, a wavelength splitter guiding the laser energy generated at the laser diode to a cavity part, and a gaining medium for amplifying the laser energy in the cavity part. The passively modelocked fiber laser further includes a reflecting means for reflecting the laser energy along an optical axis passing through the gaining medium, an output means for outputting the laser energy generated in the cavity part, and a fiber isolator provided between the laser diode and the wavelength splitter. In the passively modelocked fiber laser, the fiber isolator is composed of an optical fiber having a curved shape and including a core for propagating the laser energy, a clad for coating the core, and an optical absorption film for coating the clad.

A blood purifying apparatus having excellent purification performance (elimination of low molecular proteins, etc.) and being contaminated with little endotoxins flowing from the dialyzate side is described. Attention was paid to the solute permeability coefficient &agr; and water permeability performance Lp of blood purifying apparatus and the relation between &agr; and Lp has been examined. As a result, a blood purifying apparatus having excellent purification performance and substantially being free from invasion of endotoxins was obtained by regulating the value &agr;/Lp to 6×10−7 or above, or regulating &agr; within a range of 8×105 to 1.5×10−3, and the value &agr;×Lp to 2.4×10−2 or less. Also, a blood purifying apparatus having excellent purification performance and substantially being free from invasion of endotoxins was obtained by regulating the invasion ratio which is obtained by the polymer invasion test to 10% or less.

With a view to preventing the oxidation of a metal film at the time of light oxidation treatment after gate patterning and at the same time to making it possible to control the reproducibility of oxide film formation and homogeneity of oxide film thickness at gate side-wall end portions, in a gate processing step using a poly-metal, a gate electrode is formed by patterning a gate electrode material which has been deposited over a semiconductor wafer 1A having a gate oxide film formed thereon and has a poly-metal structure and then, the principal surface of the semiconductor wafer 1A heated to a predetermined temperature or vicinity thereof is supplied with a hydrogen gas which contains water at a low concentration, the water having been formed from hydrogen and oxygen by a catalytic action, to selectively oxidize the principal surface of the semiconductor wafer 1A, whereby the profile of the side-wall end portions of the gate electrode is improved.
