  • Patent number: 8613235
    Abstract: A continuously variable transmission includes: an input movement, a control system, a continuously variable reciprocating movement, a first holder, a second holder, a chain, an output sprocket, and a freely rotatable sprocket. The holders having the reciprocating movement. Each of the holders having a linearly movable teeth. The movable teeth are perpendicularly movable to the reciprocating movement. Each of the movable teeth having an internal end and an exposed end. The exposed end having a first slope and a second slope. The first slope having a greater slope than the second slope.

  • Publication number: 20120285783
    Abstract: A one-way clutch includes an inner ring, an outer ring, a chamber between the inner ring and the outer ring; the outer ring includes a plurality of radially inwardly extending teeth facing the chamber; each of the outer ring teeth having a first path and a second path producing an alternating crest and valley formation; the first path having a greater length than the second path; the inner ring defines a plurality of radially outwardly extending teeth facing and contacting the outer ring teeth in the chamber; the inner ring teeth are configured and positioned within the inner ring thereof, at any rotational movement of the inner ring and the outer ring, at least one of the inner ring teeth is frictionally engaged with the second path; each of the inner ring teeth having a tooth support system in the inner ring; each of the inner ring teeth is radially movable within the tooth support system; the inner ring and the outer ring having a relative rotational movement when at least one of the inner ring teeth havin

  • Publication number: 20090282326
    Abstract: A process for obtaining a result between a first numerical value and a second numerical value which are separated by a common character using a formulas in a plurality of cells of a spreadsheet is provided. If a user selects, copies and pastes a data from an application software to the spreadsheet, and the data have the common character between the two numerical values, the result is obtained using the formulas in the plurality of cells without utilizing a worksheet program for converting text to column. If the user selects, copies and pastes a new data from the application software to the spreadsheet, with this process the result is obtained using less instructions in the spreadsheet than the worksheet program to convert text to column.
