Abstract: Disclosed are a wireless transmitter and a reference signal transmission method that improve channel estimation accuracy. In a terminal, which transmits a reference signal using n (n is a non-negative integer 2 or greater) band blocks (which correspond to clusters here), which are disposed with spaces therebetween in a frequency direction, a reference signal controller switches the reference signal formation method of a reference signal generator between a first formation method and a second formation method based on the number (n) of band blocks. In addition, a threshold value setting unit adjusts a switching threshold value based on the frequency spacing between band blocks. Thus, the reference signal formation method can be selected with good accuracy and, as a result, channel estimation accuracy is further improved.

Abstract: A barium sulfate-based powder is produced by bringing barium ions (A) into contact with sulfate ions (B) in the presence of one or more metallic ion species (C) selected from the group consisting of lithium ions, sodium ions, potassium ions, magnesium ions, calcium ions, zinc ions, and aluminum ions. Thus, barium sulfate-based powders having various characteristics and thus satisfying functional requirements for cosmetics can be obtained.

Abstract: A composite powder containing a powdery base and aluminum hydroxide adhered to at least a portion of the surface of the base, wherein said adhered aluminum hydroxide in the form of a spherical and net structure is comprised preferably in a large amount. In case of using in powdery cosmetics, this composite powder hides wrinkles, pore openings and hard texture of the skin, and thus maintains the correcting effect of the troubled morphology of the skin. Thus, it exerts excellent effects of imparting natural gloss and color tone to the makeup coating without darkness, being superior in a feeling of “elasticity” and transparency, and the like, compared to the conventional products. The effect of the above object can be more enhanced by the surface treatment such as a further surface treatment by silicon on the surface of said composite powder.
