  • Publication number: 20100223291
    Abstract: With respect to each part at which a word included in a characteristic condition defining a characteristic text set designated by a user through the input device appears in text, the characteristic condition assurance degree calculating unit of the text mining device obtains a reliability of the word from the word reliability storage unit to operate a value of a characteristic condition assurance degree for each text by predetermined operation based on all the obtained reliabilities. The characteristic condition assurance degree calculating unit executes operation such that when a value of each reliability is large, a value of a degree of assurance becomes large. The representative text output unit outputs text whose characteristic condition assurance degree is the highest among texts whose characteristic condition assurance degrees are calculated together with its characteristic condition assurance degree.

  • Publication number: 20090290999
    Abstract: An engine blower includes a centrifugal blower having a volute case in which a fan is accommodated; an engine attached to the centrifugal blower for driving the fan; a carburetor mounted to the engine via an insulator; and a lead wire that establishes conduction between the engine and the carburetor. The electrical potential difference between the engine and the carburetor can be eliminated, which prevents electrostatic discharge between the engine and the carburetor even when static electricity is built up in a volute case or a ventilation tube. Accordingly, ignition timing can be prevented from shifting due to an influence on an electrical circuit by the discharge within an ignition unit.

  • Patent number: 7623954
    Abstract: An air-fuel ratio feedback control range is enlarged to improve exhaust purification performance and output stability. In one aspect, an air-fuel ratio control apparatus of an internal combustion engine comprises an air-fuel ratio sensor capable of detecting an air-fuel ratio across both lean and rich ranges with a theoretical air-fuel ratio interposed therebetween. Feedback control is performed so as to bring an actual air-fuel into a target air-fuel ratio at least in a predetermined operational range on the basis of a detected value of the air-fuel ratio sensor. Even in a range where the air-fuel ratio is made richer than the theoretical air-fuel ratio, the target air-fuel ratio is set to be richer, and the air-fuel ratio feedback control may still be executed.

  • Publication number: 20090126147
    Abstract: A portable-blower duct has a bendable portion whose inner peripheral surface is a cylindrical surface without any protrusions or recesses in a normal state or in an expanded state, that is, unless it is greatly curved. With this construction, no turbulence is generated in air passing through a tube, thereby making it possible to suppress pressure loss. Thus, the flow velocity of air guided through the duct is not reduced, thereby suppressing a deterioration in air blowing efficiency. Even when the tube is curved, the outer side of the curved portion is expanded, and the corresponding portion of the inner peripheral surface remains a smooth surface, thus making it possible to minimize the air pressure loss.
