摘要:
A flaky, fine powder comprising a flaky substance as the base and silica particles covering the surface of the base, aimed at reducing the glossiness of the base caused by the irregular reflection of light on its surface and improving the slipperiness. In particular, the powder comprises a flaky base substance such as natural mica and silica particles deposited on the base surface, wherein the silica particles may be optionally further immobilized by the hydrolysate of alkoxysilane or silica gel. The flaky fine powder is produced either by the adding alkoxysilane to a dispersion containing a flaky substance and silica particles and hydrolyzing it, by adding a silicic acid solution to the dispersion and gelling it, or by adding a combination of alkoxysilane and silicic acid solution. The powder can be compounded with various ingredients and is particularly useful with cosmetics.

A communication node which can reliably transfer a packet with a payload including data having error resistance in radio environments is disclosed. A packet to be transmitted is divided into segments to form a plurality of packet segments. From among a plurality of error correction schemes that have been prepared in advance, the scheme to be employed is selected for each of the packet segments in accordance with predetermined criteria, and the selected error correction scheme is applied to each packet segment. Subsequently, the processed packet segment is transmitted to the network. Packet segments are received from the network. From among a plurality of error correction schemes prepared in advance, the scheme to be employed is selected for each of the received packet segments based on predetermined information contained in each received packet segment, and the selected error correction scheme is applied to the received packet segment. An original packet is formed from the plurality of processed packet segments.
摘要:
A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units, determines a multiplex code on the basis of respective information amounts, derives a parity of the first determined multiplex code to form a second multiplex code, adds a CRC to each of the multiplex codes to generate two headers H1 and H2, takes out information data of respective media according to the multiplex codes, incorporates the information data into a packet together with the two headers H1 and H2, and outputs the packet. If error correction of H1 is impossible on the receiving side, error correction decoding is conducted by using the header H2. If error correction of H2 is also impossible, error correction decoding is conducted collectively for H1 and H2.
