Abstract: A laser apparatus includes an output coupling mirror; a grating that constitutes an optical resonator together with the output coupling mirror; a laser chamber in an optical path of the optical resonator; at least one prism in an optical path between the laser chamber and the grating; a rotary stage including an actuator that rotates the prism to change an incident angle of a laser beam from the laser chamber on the grating; a wavelength measuring unit that measures a central wavelength of the laser beam from the laser chamber through the output coupling mirror; an angle sensor that detects a rotation angle of the prism; a first control unit that controls the actuator at a first operation frequency; and a second control unit that controls the actuator at a second operation frequency.

Abstract: Disclosed is a mask composition comprising: (1) a water insoluble substrate; and (2) an emulsified liquid composition comprising: (a) an oily component; (b) a hydrophilic surfactant; (c) a water-soluble thickening polymer which provides the liquid composition a viscosity of from about 500 mPa·s to about 60,000 mPa·s; and (d) an aqueous carrier.

Abstract: Treatment articles capable of conforming to an underlying shape and methods for their use are provided. The articles comprise a water insoluble substrate having at least one elongation zone where at least a portion of the elongation zone has been incrementally stretched. The article also includes a treatment composition which preferably delivers a skin care active. Preferred articles of the present invention comprise facial treatment masks.

Abstract: Disclosed are cosmetic treatment articles comprising: (1) a water-insoluble substrate; (2) a gel composition comprising: (a) a first gel forming composition comprising a water soluble polymeric gelling agent and (b) a second gel forming composition comprising a gel strengthening agent; and (3) preferably, a treatment composition comprising a rheology modifier. Further disclosed are cosmetic treatment articles comprising at least two different treatment compositions, each treatment composition being provided at one or more selected locations on the water insoluble substrate.

Abstract: A material capable of occluding/discharging a lithium ion or a lithium-ion-conducting material is made to adhere to a surface of a particle of a lithium transition metal composite nitride having a particle diameter of 0.01 to 30 ?m by a vapor phase method represented by a thin-film forming method selected from chemical vapor deposition, vapor deposition, ion plating and sputtering, thereby providing a composite electrode material with improved stability in the air as an electrode material capable of constituting an electrochemical element having a large capacity and improved cycle characteristics.
