  • Patent number: 7165516
    Abstract: An inventive cooling unit for an internal combustion engine comprises a plurality of cooling fins provided on outer surfaces of a cylinder block and a cylinder head, and vibration control rubbers interposed between cooling fins that face each other so as form a cooling air guide which guides air flow along lateral sides of the engine to rear parts of the engine. The cooling unit significantly increases the cooling efficiency of a cylinder and prevents vibration of cooling fins by interposing vibration control rubbers between cooling fins that face each other. The vibration control rubbers are formed in a streamlined shape and direct the flow of traveling air within the cooling fins about the exterior surface of the engine. The arrangement of the vibration control rubbers on side surfaces of the engine is such that angle ? of longitudinal axes of the vibration control rubbers with respect to the advancing direction of the vehicle becomes gradually larger moving from the front to the rear of the engine.

  • Patent number: 7080395
    Abstract: There is provided an information processor and an information processing method for effectively utilizing EPG data. Identification codes for identifying specific character parts such as names of the cast of a program described in a description text describing the detail of the program in EPG data are inserted within the description text and are transmitted by a transmitter. Based on the identification codes inserted in the EPG data, the specific character parts are sampled from the description text and predetermined processing steps are performed based on the sampled result in a receiver. That is, the display color of the specific character parts is differentiated from that of the other part in displaying the description text on a monitor for example. Or, a list of the names of the cast of the program is displayed as the sampled specific character parts and when the user selects a certain player, EPG of the program in which the player appears is displayed.
