摘要： This invention provides an anti-counterfeit printed matter which forms an invisible image that can be visualized clearly and also prevents a visible image from impeding visibility of a visualized invisible image. In the anti-counterfeit printed matter according to this invention, a plurality of object elements are arranged at a predetermined pitch in a matrix, each object element including a first object and a second object which are arranged along a first direction on both sides of a boundary at a center so as to oppose each other, and a third object and a fourth object which are arranged along a second direction perpendicular to the first direction on both sides of a boundary at the center so as to oppose each other. The first object and the second object, and the third object and the fourth object of each object element have a negative/positive relationship. The first object and/or the second object forms a first invisible image. The third object and/or the fourth object forms a second invisible image.

摘要： The invention is applied to an internal combustion engine in which fuel cut control is performed. The internal combustion engine has an exhaust gas recirculation system including: an exhaust gas recirculation passage that connects an intake and exhaust passage of the engine; and an exhaust gas recirculation valve that changes a cross section of the exhaust gas recirculation passage. A correlation, which holds during a predetermined period of time immediately after fuel cut control is stopped, between engine rotation speed NE and an index value indicating the amount of burned gas contained in the recirculated exhaust gas that passes through the exhaust gas recirculation valve (S101 to S104). The correlation is stored in an electronic control unit in advance (S105). Immediately after the fuel cut control is stopped, the index value indicating the burned gas amount is computed from the correlation stored in the electronic control unit based on the engine rotation speed NE.
