摘要:
The present invention provides an antiwrinkle agent and skin cosmetic composition having excellent alleviating effects on wrinkles appearing due to aging, and especially at exposed locations of skin, and a high degree of safety. The present invention relates to an antiwrinkle agent and skin cosmetic composition comprising a sclareol derivative represented by the following structural formula (1).

The invention provides a surfactant comprising at least one trehalose-6-fatty acid ester selected from those represented by the following formula: wherein R represents a saturated or unsaturated acyl group having 8-22 carbon atoms, and may have a hydroxyl group or other substituents, and an emulsion-type cosmetic composition comprising said surfactant and a water-soluble polymer. The surfactant of the invention has excellent surface activity and safety. Also, the emulsion-type cosmetic composition has excellent long-term storage stability and sensory properties, has no irritation to skin, and gives beautiful appearance with fine surface texture. Further, the invention is a liposome having a membrane wall composed of trehalose fatty acid ester. Said liposome has excellent chemical and physical stabilities such as long-term storage stability.
摘要:
A position sensor is provided with a displacement signal output circuit 1 that amplifies an electromagnetically induced and detected current signal from a slider and converts the result to a rectangular wave signal; a phase difference detection circuit that compares the output signal from the displacement signal output circuit with a clock signal employed for producing the alternating current component from the scaler and detects the phase difference; and an interpolation pulse counter that determines digital displacement data from the phase difference detected at phase difference detection circuit using interpolation pulses. Further, an averaging circuit is provided at the output stage of this interpolation pulse counter which calculates and outputs an average value of a plurality of instances of digital displacement data successively calculated by the interpolation pulse counter.
摘要:
In an induction sensor, a plurality of positioning holes are formed through each of a scaler and a slider. The positioning holes of the scaler and slider are spaced the same distance from respective coils and are of the same size and arranged at the same interval. The gap length and azimuth angle between the scaler and the slider are maintained with accuracy.
