摘要:
An oil-in-water type emulsion composition comprising: an amphiphile and a surfactant selected from the substances which can form a gel in an amphiphatic substance-surfactant-water system at a temperature of not lower than ordinary temperatures; oil and water, wherein substantially the total amount of amphiphile and surfactant exist on the boundary surfaces of emulsion particles. The emulsion composition has both the physical properties close to those of an aqueous solution and a creamy feel at the time of use.

摘要:
To provide a scanning probe microscope wherein the scanning means is not damaged by fluids, the scanning probe microscope 30 comprises a cantilever support part 2 for supporting a cantilever 1; displacement measurement parts 3, 4, 5 and 6 for measuring the displacement of the cantilever 1; a specimen container 11 comprising sidewalls 19 and bottom surface 18 and containing a fluid 10 and a specimen S; a carrying stage 40 on which the specimen container 11 is placed; and a scanning means 7 for moving and scanning the carrying stage 40. While the cantilever 1 is immersed in the fluid 10 that is contained in the specimen container 11, the carrying stage 40 is moved, and the displacement of the cantilever 1 is measured. The scanning probe microscope 30 further comprises a ring-shaped protective mat 50 that is capable of absorbing the fluid 10. A mounting mechanism 43 is formed on the outer peripheral surface of the carrying stage 40 for removably attaching the protective mat 50 by its inner peripheral area.
摘要:
Artificial skin having a thickness of 100 to 1,000 μm, and prepared from a polymer which, when formed into a thin film having a thickness of 100–1,000 μm, exhibits a percent transmission of light having a wavelength of 450–280 nm of at least 10%. In the artificial skin of the present invention, grooves which imitate furrows are provided on one surface. Also disclosed is a method for evaluating UV screening agents making use of the artificial skin of the present invention, on the basis of the relation between UV shielding power of a UV screening agent and UV transmission through the artificial skin.

An emulsion for hair treatment is provided which is characterized by the following: the formulation (I) is composed of a W/O type emulsion, which allows the main agent to be stable, and contains preferably an oil soluble polymer compound for the emulsifier; the formulation (I), upon being mixed with formulation (II), can easily undergo demulsification and a phase inversion into an O/W type emulsion; and the emulsion has adequate viscosity to prevent dripping from the hair and a superior dyeing capability. Also, 2-formulation type oxidation hair dye with an excellent hair dyeing effect is provided by adding isostearyl alcohol.

An optical information processing apparatus includes an optical head for irradiating a light beam onto an optical recording medium, an objective lens, mounted on the optical head, for condensing the light beam onto the recording medium, a photodetector for receiving a light beam from the recording medium and for generating a tracking error signal indicative of a positional deviation between a light beam irradiated position and a track, a tracking actuator for moving the objective lens in a direction intersecting tracks of the recording medium, a tracking controller for driving the tracking actuator in accordance with the tracking error signal so as to correct the positional deviation, a position detector for detecting a relative position of the objective lens with respect to the optical head in the direction intersecting the tracks, a measuring device for measuring a relationship between an offset of the tracking error signal and a position of the objective lens from the tracking error signal and an output of the position detector, a memory for storing the relationship measured by the measuring device and a correction device for correcting the offset of the tracking error signal in accordance with the stored relationship, in response to the position detector output signal.
摘要:
In an array of coke ovens each including a plurality of combustion chambers having a plurality of flue nozzles, a measuring car equipped with a temperature measuring member runs above the array in a direction of the array or in a longitudinal direction of the combustion chambers so as to detect thermal radiations passing through the flue nozzles to measure combustion chamber temperature. The measured temperature is sent to a remote control room through antennae. Where a coal charging car of a Rahmen construction is used an antenna is also provided for the coal charging car so that even when the measuring car runs beneath the coal charging car, radio communication can be assured. The temperature of the combustion chambers can be readily and accurately measured by linearly running the measuring car whether combustion is effected in one or the other side of the combustion chambers.
摘要:
The present invention is an oil-in-water emulsion composition containing a hydrophilic non-ionic surfactant or hydrophilic anionic surfactant, a higher aliphatic alcohol, water, and an oil ingredient which meets specific conditions. This is an oil-in-water emulsion composition with good high temperature stability and usability, and can be used as a cream-like endermic liniment such as a cosmetic.

A process for producing a metal body comprises (1) a step of maintaining under reduced pressure a metal material within a temperature range of room temperature to a temperature lower than a melting point of the metal in a sealed vessel to thereby degas the metal material, (2) a step of melting the metal material under pressurization by introducing a gas into the sealed container to thereby dissolve the gas into the molten metal, and (3) a step of cooling and solidifying the molten metal while controlling a gas pressure and a molten metal temperature in the sealed vessel to thereby form a porous metal body.
