20150082776 | METHOD FOR IMPROVING DURABILITY OF EXHAUST PIPE, AND EXHAUST GAS PURIFICATION APPARATUS - In an exhaust gas purification apparatus or other apparatuses that are supplied with ammonia generated from a urea aqueous solution and causes selective reduction and purification of nitride oxides, a shot peening treatment is applied to a welded portion of its exhaust pipe which is made of a ferritic stainless steel plate and through which exhaust gas containing ammonia and hydrogen passes. By shot peening the welded portion of the exhaust pipe, a tensile residual stress in the welded portion of the exhaust pipe can be replaced with a compressive residual stress, and further the diameter of metal crystal grains in the welded portion can be reduced. In this way, the durability of the exhaust pipe can be improved. | 03-26-2015 |

20150045495 | PIGMENT COMPOSITION, METHOD FOR PRODUCING THE SAME AND AQUEOUS INKJET INK - There is provided a method for producing a pigment composition which contains a polymer-treated pigment (D) containing an azo lake pigment (A) and an aqueous polymer (C) precipitated with a polyvalent metal salt (B) and also contains a polymer (F) obtained by polymerizing a polymerizable unsaturated monomer (E) in the presence of the polymer-treated pigment (D). The method includes: synthesizing an azo dye by coupling a coupler component with a diazo component obtained by diazotizing an aromatic amine; and preparing the polymer-treated pigment (D). The method also includes producing the polymer (F) by polymerizing the polymerizable unsaturated monomer (E) in the presence of the polymer-treated pigment (D) to coat the polymer-treated pigment (D) with the polymer (F). | 02-12-2015 |

20150232758 | LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a liquid crystal display device that prevents a decrease in the voltage holding ratio (VHR) and an increase in the ion density (ID) in the liquid crystal layer, and resolves the problems of display defects, such as white streaks, variations in alignment, and image sticking. Since a liquid crystal display device according to the present invention has a feature of preventing a decrease in the voltage holding ratio (VHR) and an increase in the ion density (ID) in the liquid crystal layer, and suppressing the occurrence of display defects such as image sticking, the liquid crystal display device is particularly useful for active matrix driving liquid crystal display devices with an IPS mode or an FFS mode and can be applied to liquid crystal display devices such as liquid crystal televisions, monitors, cellular phones, and smart phones. | 08-20-2015 |
