1. A method for the production of resin particles, the method comprising the steps of
melting and mixing a thermoplastic resin or elastomer having one or more carboxyl groups or carboxylic anhydride groups with filler particles and a water-soluble material to form a resin composition, the resin composition including a matrix and resin fine particles dispersed in the matrix, the resin fine particles formed from the thermoplastic resin or elastomer and the filler particles, and the matrix formed from the water-soluble material; and
removing the matrix component from the resin composition to give the resin particles, wherein the amount of carboxyl groups and carboxylic anhydride groups in the thermoplastic resin or elastomer before mixing and kneading step is 5 mmolkg or more based on the total amount of the thermoplastic resin or elastomer, and the resulting resin particles each include the filler particles immobilized on the surface of the resin particle to produce a core-shell structure wherein the core comprises the resin particle and the shell comprises the filler particles;
wherein the water-soluble material is selected from the group consisting of monosaccharides, oligosaccharides, sugar alcohols, polydextroses, maltodextrins, inulins; hydrates and hydrolysates thereof;
the removing step comprising: dissolving the pellets of resin composition in water, water- soluble organic solvents, or mixtures thereof; filtrating the resulting solution of resin composition under reduced pressure; repeating the washing process including dissolving and filtrating to remove the water-soluble material and to give a wet cake; and drying the wet cake under reduced pressure to give resin particles,
wherein the thermoplastic resin or elastomer having one or more carboxyl groups or carboxylic anhydride groups is selected from polyamide resins and polyamide elastomers.
2. The method for the production of resin particles, according to claim 1, wherein the filler particles have a particle size of from 0.001 to 100 \u03bcm, and wherein the resulting resin particles have a particle size of from 0.5 to 80 \u03bcm.
3. The method for the production of resin particles, according to claim 1, wherein the filler particles have been treated with a surface treating agent containing a basic group.
4. The method for the production of resin particles according to claim 1, wherein the filler particles are inorganic fillers selected from the group consisting of calcium carbonate, magnesium carbonate, clay, kaolin, calcium phosphate, hydroxyapatite, mica, talc, silica, quartz powder, glass powder, diatomaceous earth, nepheline syenite, cristobalite, wollastonite, aluminum hydroxide, iron oxide, zinc oxide, titanium oxide, aluminum oxide, calcium sulfate, barium sulfate, dolomite, silicon carbide, silicon nitride, boron nitride, metallic powders, graphite, and carbon black.
5. The method for the production of resin particles according to claim 3, wherein the surface treating agent is a silane coupling agent.
6. The method for the production of resin particles according to claim 1, wherein the water-soluble material has a viscosity as low as possible when dissolved in a disperse medium.
7. The method for the production of resin particles according to claim 6, wherein the disperse medium is water.
8. Resin particles produced by the method of any one of claims 1, 2, 3, 4, or 5.
9. A cosmetic comprising the resin particles of claim 8.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A computer-implemented method, the method comprising:
receiving a search query from a user accessing a client device;
identifying a context file;
selecting one or more document collections specified in the context file;
obtaining, from the one or more selected document collections, one or more context processed search results that are responsive to the search query;
ranking the context processed search results based on, at least, one or more ranking parameters specified in the context file, wherein the ranking parameters include one or more weights for adjusting respective scores of the context processed search results;
providing the ranked context processed search results to the client device; and
wherein identifying, selecting, obtaining, ranking, and providing are performed by data processing apparatus.
2. The method of claim 1, wherein the context file is identified based on the search query, the client device, the user accessing the client device, or user site behavior of the user accessing the client device.
3. The method of claim 1, wherein the context file is provided by the client device, a third-party content provider, or a search engine system.
4. The method of claim 1, wherein the one or more weights for adjusting scores associated with the context processed search results are based on a search result document length.
5. The method of claim 1, wherein the one or more weights for adjusting scores associated with the context processed search results are based on a search result document publication date.
6. The method of claim 1, wherein the one or more weights for adjusting scores associated with the context processed search results are based on a search result document format.
7. The method of claim 1, wherein the one or more weights for adjusting scores associated with the context processed search results are based on the one or more selected document collections.
8. The method of claim 1, wherein the one or more weights for adjusting scores associated with the context processed search results are based on respective quality measures specified for documents referenced by the context processed search results.
