  • Publication number: 20210366324
    Abstract: A content generation method generates image content to be projected at a projection position in a real space by a projector. In a first acquisition process, space information regarding a virtual space corresponding to the real space is acquired. In a second acquisition process, display position information regarding a display position corresponding to the projection position in the virtual space is acquired. In a third acquisition process, reference position information regarding a reference position in the virtual space is acquired. In a generation process, an image including an object viewed from the reference position when the object is displayed at the display position in the virtual space is generated as the image content, based on the space information, the reference position information, and the display position information.

  • Patent number: 8033102
    Abstract: An exhaust emission control device for an internal combustion engine, which is capable of terminating reduction control in proper timing when a NOx cleaning catalyst includes an auxiliary catalyst having an oxygen storage capacity, thereby making it possible to reduce exhaust emissions and improve fuel economy. The exhaust emission control device includes the NOx cleaning catalyst and an ECU. The NOx cleaning catalyst includes the auxiliary catalyst having an oxygen storage capacity. The ECU executes reduction control when predetermined conditions for executing the reduction control are satisfied. During execution of the reduction control, when exhaust gas temperature is higher than a predetermined value, if a second excess air ratio is lower than a predetermined value, the ECU determines that the reduction control should be terminated.

  • Publication number: 20090280413
    Abstract: There is obtained a carbon material for lithium-ion secondary battery negative electrode, a low-crystalline carbon impregnated carbon material for lithium-ion secondary battery negative electrode, a negative electrode plate, and a lithium-ion secondary battery, each of which realizes a first charge/discharge cycle with less gas generation and provides a rapid charge/discharge. The carbon material is obtained by: blending and kneading a carbonaceous aggregate with a binder to form a composition; press molding the composition into an article; carbonizing the press molded article; graphitizing the article to obtain an artificial graphite block; milling the block; and carrying out particle size control. The carbon material has characteristics of: (1) R-value=(I1360/I1580)?0.2, where R-value is defined by the ratio of D band to G band in Raman spectrum using Nd:YAG laser light of 532 nm wavelength; and (2) d(002)?0.
