| 20090011347 | ELECTROPHOTOGRAPHIC TONER, ELECTROPHOTOGRAPHIC DEVELOPER, TONER CARTRIDGE, AND IMAGE FORMING METHOD - The invention provides an electrophotographic toner having a crystalline polyester resin; a non-crystalline polyester resin; a colorant; and a releasing agent. A resin (i), that is included in a toluene-soluble component of the toner and having a molecular weight of 30,000 to 100,000 as measured by gel permeation chromatography relative to polystyrene standards, has an acid value A. A resin (ii), that is included in a toluene-soluble component of the toner and having a molecular weight of 8,000 to 12,000 as measured by gel permeation chromatography relative to polystyrene standards, has an acid value B. A resin (iii), that is included in a toluene-insoluble component of the toner, has an acid value C. The acid values A, B, and C satisfy the inequation of B>A>C. The invention further provides an electrophotographic developer using the toner, a toner cartridge storing the toner, and an image forming method using the developer. | 01-08-2009 |

| 20090047655 | Method Of Screening Candidate Drug - It is intended to provide a method of screening a candidate drug mainly metabolized by a drug metabolizing enzyme, CYP2D6, CYP2C9 or CYP2C19 with the use of a chimeric mouse carrying human hepatocytes transplanted thereinto, whereby it is determined whether or not the candidate drug is metabolized in a subject deficient in CYP2D6, CYP2C9 or CYP2C19. It is also intended to provide a method of determining whether or not a candidate drug induces or inhibits the activity of any of drug metabolizing enzymes, CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 with the use of a chimeric mouse carrying human hepatocytes transplanted thereinto. | 02-19-2009 |
| 20090112013 | PREPARATION OF SI-SI BOND-BEARING COMPOUNDS - Si—Si bond-bearing compounds are effectively prepared by irradiating with radiation or heating Si—H group-bearing silicon compounds in organic solvents in the presence of iron complex catalysts. The Si—Si bond-bearing compounds are useful as a base material in photoresist compositions, ceramic precursor compositions, and conductive compositions. | 04-30-2009 |
| 20100030829 | Method of generating random numbers - A method of obtaining uniform and independent random numbers is given (a) comprising two distinct odd primes p | 02-04-2010 |
