A stratum corneum sheet is contacted with a solution of a water-soluble dye, and the staining intensity or fluorescence intensity is measured to allow convenient evaluation of the stratum corneum condition. There is further provided a method for evaluating the ameliorating effect of a cosmetic or cosmetic treatment on the stratum corneum, by implementing the method for evaluating stratum corneum condition using a water-soluble dye according to the invention.

Abstract: It is an object of the invention to provide a method for evaluating cosmetics that allows development of cosmetics that can contribute to beautiful healthy skin. The object is achieved by a method of evaluating improvement in skin by an applied cosmetic, using as the index the change in stratum corneum thickness during the process of moistening and drying.

Abstract: An image analysis apparatus that analyzes a skin condition from a video of the face of a subject captured with an imaging part includes a tracking part configured to track the amount of changes of multiple tracking points arranged in advance in an analysis region of the face based on a change in the expression of the face included in the video, and obtain the compression ratio of the skin in the analysis region based on the amount of changes, and a skin condition analysis part configured to analyze the skin condition of the subject based on the compression ratio obtained by the tracking part.

Abstract: The purpose of the present invention is to provide a rapid and widely practicable cosmetic-evaluating method for evaluating the performance of candidate cosmetics in improving wrinkles in the horny cell layer. Provided is a method for evaluating the effectiveness in wrinkle improvement of a candidate cosmetic by immersing a horny-cell-layer sheet having creases and wrinkles in the candidate cosmetic, and verifying the disappearance of the creases and wrinkles after drying, whereby the purpose is achieved.

Abstract: In supplying flux to a brazing heat exchanger member, a given amount of the flux is stably adhered to brazing portions without interposing any substance which becomes unnecessary for the brazing such as binder. In manufacturing a heat exchanger member, particles containing flux are injected to a surface of a substrate made of aluminum or its alloy at a temperature lower than a melting point of the flux by 30° C. or more to collide against the surface at an average speed of 100 m/sec or higher to thereby mechanically adhere the particles thereto.

Abstract: The present invention provides a method for evaluating the transparency and/or water holding capacity of a stratum corneum by using oxidized protein in the stratum corneum as an indicator.

Abstract: A production method of a heat exchanger member to be brazed includes spraying particulate powder of metal less noble in corrosion potential than Al, an alloy of the metal, or a composition of the metal, at 150° C. or less at high speed onto a surface of a substrate of aluminum or its alloy to thereby make the particulate powder adhere to the surface. The metal is diffused in the surface layer portion of the substrate by the brazing heating to form a sacrificial corrosive layer.

Abstract: A clad member low in thermal expansion coefficient and excellent in workability is provided. The clad member 1 comprises a core member 11 and skin members 12 cladded on both sides of the core member. The core member 11 is constituted by an aluminum alloy consisting of Si: 5 to 30 mass %, and the balance being aluminum alloy and impurities. The skin member 12 is constituted by aluminum or an aluminum alloy consisting of Al: 98 mass % or above, and the balance being impurities.

Abstract: The invention relates to heat sinks made of finned aluminum extrudates and useful for electronic devices and information devices having an electronic device incorporated therein. The heat sink of the invention made of a finned aluminum extrudate comprises a base plate, and fins arranged in parallel and provided on one surface thereof. The base plate is 25 to 400 mm in width, 25 to 400 mm in length and 2 to 5 mm in thickness, and the fins are 1 to 30 mm in height, 1 to 1.9 mm in interval and 0.1 to 0.8 mm in thickness. The thickness of the fins is reduced within a predetermined range according to the invention to thereby ensure diminished resistance to the flow of air and improved radiation performance. This also renders the heat sink lightweight, serving to reduce the size and weight of electronic devices and information devices.

Abstract: In a friction agitation joining method for joining metallic joining members, a joining device having a column-shaped rotor of a larger diameter and a pin-shaped probe of a smaller diameter integrally formed on an end of the rotor and protruded along an axis of the rotor is used for joining the metallic joining members. The probe is rotated and inserted into or around a butted portion of the joining members to soften a contact portion contacted by the probe by friction heat and to agitate the contact portion so that the joining members are butt joined. Each joining member has a thick portion at a butting side thereof The rotating rotor is contacted to the thick portions under pressure to soften the thick portions by friction heat so that a gap formed at the butted portion is filled with the materials of the softened thick portions.
