  • Publication number: 20060064892
    Abstract: In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.

  • Publication number: 20050202189
    Abstract: A mat-shaped thermal insulator made of inorganic fiber, wherein at least a part of inorganic fibers is built-up in a direction parallel to lateral surfaces of the insulator, and said insulator is formed by cutting a fibrous built-up article formed by building-up inorganic fibers, to form cut built-up articles, rotating at least one of the cut articles by an angle of 90 degrees in a direction perpendicular to a longitudinal direction, to form a rotated built-up article in which the inorganic fibers are built-up in a direction parallel to lateral sides of the cut article, and integrating the cut articles and/or the rotated article transversally in a direction perpendicular to cutting direction. Preferably, the lateral surfaces of the insulator are inclined. Still preferably, longitudinal cuts are formed on the lateral surfaces of the insulator so as to make the insulator partially compressible.

  • Publication number: 20050136554
    Abstract: An Al2O3 film for covering a ferroelectric capacitor is formed by a sputtering process. The thickness of the Al2O3 film is preferably optimized according to amount of remanent polarization and fatigue tolerance required for the ferroelectric capacitor, for example, 10 nm to 100 nm. Next, oxygen is supplied to a PZT film via the Al203 film by executing a heat treatment in an oxygen atmosphere. As a result, an oxygen deficit in the PZT film is made up for. At this time, evaporation of Pb in the PZT film is suppressed because of the Al2O3 film, and deterioration of the fatigue tolerance responsive to decrease of Pb amount is suppressed. Subsequently, another Al2O3 film is formed as a second protective film by the sputtering process for opposing the deterioration factor in later process. The thickness of the Al2O3 film is preferably the thickness which sufficiently protects the ferroelectric capacitor from the deterioration factor in later wiring process.

  • Patent number: 6597288
    Abstract: An improved fire alarm system capable of reliably detecting the presence of fire caused by different sources. The fire alarm system detects a smoke density (S) as well as a temperature difference (&Dgr;T) within a predetermined time interval, and has primary criteria of (i) whether the smoke density (S) exceeds a smoke threshold [e.g., S>5%/m]; (ii) whether the temperature difference (&Dgr;T) exceeds a temperature difference threshold [e.g., &Dgr;T≧18 C]; and (iii) whether a combination of S and &Dgr;T satisfies an inequality [e.g. 2S+&Dgr;T≧12] which is based upon a decreasing function of &Dgr;T with an increase of S. The detected smoke density and the temperature difference are examined with reference to the primary criteria so as to provide a fire warning signal indicating a possible fire presence when anyone of the above primary criteria is satisfied.
