According to "Nihon Keizai Shimbun" reported on June 8, Takara Tomy, a large Japanese toy manufacturer, announced on June 4 that it has jointly developed a small robot "OHaNAS" with Japanese mobile communication operator NTT DOCOMO. The robot can communicate naturally with people. For example, you can chat casually according to the latest topics on the Internet, or you can answer questions such as recipes that the user asks after querying. The price does not include tax of 19,800 yen (about 990 yuan) and will be available in October. In the situation of Japan's growing childpower, the company has used dialogue robots that adults will like as a breakthrough in expanding the customer base. Takara Tomy, a large Japanese toy maker, announced on June 4 that it has jointly developed a small robot "OHaNAS" with Japanese mobile communication operator NTT DOCOMO. After downloading the application software provided by Dome through the smartphone and tablet terminal, the user connects it to DOCOMO's cloud technology language processing system. The OHaNAS can be connected to a smart phone or the like via a short-range wireless network. At present, OHANAS's sales target is 100,000 units a year, but Harold George Meij, vice president and chief operating officer of Dome, said, "If you can support foreign languages, the demand will be infinite." It is planned to launch an English-speaking OHANAS within one year. Softbank will also be available in the summer to talk to the humanoid robot "Pepper", the price is not included in the tax of 198,000 yen (unit price). Although OHaNAS can't use gestures like Pepper, and it can speculate on the emotions after reading the expression through image recognition function, but the price is close to the people, and can be placed on the desktop at will, which is "easy to use".
Dye is an organic substance that enables the coloring of fibers and other materials. Dye a wide range, according to the source can be divided into natural dyes (such as plant dyes, animal dyes and mineral dyes, etc.) and synthetic dyes (or artificial dyes). According to the molecular structure can be divided into azo dyes, anthraquinone dyes, phthalocyanine dyes, aromatic methane dyes, nitro dyes and so on. According to the application method is divided into acid dyes, alkaline dyes, sulfur dyes, reactive dyes, disperse dyes, direct dyes and so on. Dye has a color, but the color of the material is not necessarily a dye. Dyes must have chromophores and help chromophores. The dye in the ink should also have a water-soluble group such as a sulfonic acid group.
Natural dyes are dyes obtained from animals, plants and minerals. According to the source can be divided into: â‘ plant dyes, from some plants roots, stems, leaves and fruits extracted from the dye, such as extracted from indigo indigo (blue), extracted from turmeric curcumin (yellow (Dinar), etc.); (d) dyes, extracts from the animal's body, such as carmine extracted from the cochineal, etc .; (d) mineral dyes, dyes extracted from the colored non-ferrous minerals of minerals , Such as chrome yellow, ultramarine, manganese brown and so on. Because of the natural dyes and artificial dyes compared to the existence of many shortcomings, such as incomplete chromatography, application inconvenience, poor fastness, in addition to a few still use, the majority was eliminated.
Synthetic dyes, also known as "artificial dyes". Mainly by the coal tar (or oil processing) fractionation products (such as benzene, naphthalene, anthracene, carbazole, etc.) by chemical processing, sometimes called coal tar dyes. As the first few kinds of synthetic dyes made of aniline as raw materials, it is also known as "aniline dye." Compared with natural dyes, synthetic dyes and more types, chromatography complete, most colorful, washable and durable, and can be mass production. So the current so-called dye almost all refers to synthetic dyes. The dyeing products are one of the common forensic materials.
Pigment is a colored, black, white or fluorescent particulate organic or inorganic solid. In water, oil or other application medium does not dissolve, but can be evenly dispersed, and in the entire dispersion process from the physical and chemical effects of the media, still retain its unique crystal or particle structure. According to the chemical composition of inorganic pigments and organic pigments; according to the color is divided into white, red, yellow, black and other pigments; according to the source is divided into natural and synthetic pigments, natural pigments are mineral (inorganic) such as He Shi, cinnabar, , Realgar, etc., there are animal and plant (organic) such as rattan, cochineal red, synthetic pigments are also inorganic and organic two categories; according to the use of coloring pigments, physical pigments and functional pigments. Coloring pigments are inorganic and organic pigments that impart various colors to the application medium. The pigment is a pigment that does not have a hue force and no hiding power. It is mainly used to reduce product cost and improve the performance of paint, plastic, rubber and other products. Called the filler. Now has been processed into ultra-fine grain of natural products and synthetic products, due to the synthesis of impurities in the small, fine particles and according to the need for artificial synthesis and a variety of surface modification, it can be used to reduce the hiding power of the pigment (Such as titanium dioxide) and improve product performance, and now it is called physical (incremental) pigments more appropriate, most of the main varieties of natural pigments are processed natural minerals such as natural calcium carbonate, barite powder, talc Such as precipitated calcium carbonate, precipitated barium sulfate, synthetic silica, etc .; functional pigments are pigments that give products specific functions, And change the color of the temperature paint, with poisonous biological function of the antifouling pigments, in the dark glowing luminous pigments, to prevent corrosion of rust-proof paint, pearl luster pearlescent pigments and so on.
Paint in paint, printing, rubber, plastics, paper, fiber, ceramics and other industries widely used, the product can be decorative, opaque, durable or special features.

OHaNAS analyzes the speaker's intentions and logic and conducts dialogue. For example, when the other party says "washing clothes," OHANAS will search for information on the Internet, and then answer answers such as "It's raining tomorrow, it's best not to wash."
