20110246048 | FUEL INJECTION CONTROLLER - When an engine driving condition has been changed from an idling condition to a vehicle running condition, a controller measures an idling period. When the idling period is longer than a determination time period immediately after the vehicle is started, a penetrating-force-decrease control is performed. Therefore, even when a piston temperature is relatively low and particulate matters are easily generated, it can be restricted that fuel adheres to the piston top-surface by performing the penetrating-force-decrease control. Further, in the penetrating-force-decrease control, since the fuel is injected at optimum injection timing, it can be avoided that emission and fuel economy are deteriorated. | 10-06-2011 |

20150217332 | METHOD FOR FORMING EXCELLENT MULTI-LAYER COATING FILM - The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained. In the method, the light reflectance of the metallic base coating film is in a specified range and the light transmittance of the single color base coating film obtained by heat-curing the color base coating film as a single film is adjusted to a specified range. | 08-06-2015 |
