摘要:
In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. The exhaust purification catalyst (13) is comprised of a mixture of a first catalyst in which platinum (51) and a basic layer (52) are carried on alumina (50) and a second catalyst in which rhodium (56) is carried on zirconia (55). The concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to vibrate by within a predetermined range of amplitude of a 200 ppm or more and within a predetermined range of period of 5 second or less, whereby the NOx which is contained in exhaust gas is reduced at the exhaust purification catalyst (13).

A resin composition for an aqueous coating material that includes a propylene-butene resin component and/or propylene-ethylene-butene resin component (A), and a (meth)acrylic resin component (B), wherein the mass ratio between the propylene-butene resin component and/or propylene-ethylene-butene resin component (A) and the (meth)acrylic resin component (B) is within a range from 15:85 to 75:25. Also disclosed are a method for producing such a resin composition and an aqueous coating material. The present invention is able to provide a resin composition for an aqueous coating material that is useful as a binder within an aqueous coating material that uses no organic solvents or chlorine compounds, and yet exhibits excellent adhesion to polyolefin-based resins and is capable of forming a coating film that is resistant to discoloration and exhibits favorable resistance to the oils contained within gasoline, cosmetic products and foodstuffs and the like, and is also able to provide a method for producing the resin composition and an aqueous coating material that uses the resin composition.

Disclosed is an exhaust gas purifying catalyst in which grain growth of a noble metal particle supported on a support is suppressed. Also disclosed is a production process for producing an exhaust gas purifying catalyst. The exhaust gas purifying catalyst comprises a crystalline metal oxide support and a noble metal particle supported on the support, wherein the noble metal particle is epitaxially grown on the support, and wherein the noble metal particle is dispersed and supported on the outer and inner surfaces of the support. The process for producing an exhaust gas purifying catalyst comprises masking, in a solution, at least a part of the surface of a crystalline metal oxide support by a masking agent, introducing the support into a noble metal-containing solution containing a noble metal, and drying and firing the support and the noble metal-containing solution to support the noble metal on the support.

A communication method controlling system includes a control apparatus and a writing apparatus. The writing apparatus includes a function that employs plural communication methods. When a user selects content by manipulating an operation terminal, a control apparatus detects the content ID, and transmits corresponding content data and communication method information to the writing apparatus. Based on the received content data, the writing apparatus writes the contents data and displays a content image on electronic paper, and changes a communication method according to the received communication method information and uses an LED lamp, for example, to notify the user which communication method has been selected. When the user performs an operation according to the available communication method, information is transmitted from the writing apparatus to a port using the communication method.
