Abstract:
PURPOSE: Stand machine is provided which uses two lines of rail to stand the fallen rice again so that it shortens time in standing rice. CONSTITUTION: The stand machine comprises the parts of: a length rail which is firmly placed on an across rail; a machine base(11) which is placed on the length rail to move horizontally and wherein a long arm is eccentrically moved in a vertical way; a rake which is fallen straight by a press motor that changes speed at lower speed; and a serpent which passes through the lower part of the fallen rice to raise the machine for standing rice and press a bend by the machine for bending rice groups.
Abstract:
In a structure for an automatic transmission gear and a manual transmission gear, one end of a plate spring is connected to an engine crank shaft and the other end of the plate spring is connected to an input shaft of a transmission to perform a function of a torque converter as a clutch in an automatic transmission, and a disk clutch in a manual transmission; thus a car can smoothly depart by winding up the plate spring when the clutch is operated. The structures stated before are described in details in the specification. [Index] car, transmission.
Abstract:
A bicycle used as a common means of transportation has gears changed to run uphill from a flat road at low speeds. In a normal bicycle frequently changing gears corresponding to the conditions of a road, a gear shift structure has gears shifted by changing a position of a lever located somewhere on a handlebar. According to the present invention, an automatic gearshift structure of a bicycle separates a crank shaft and a driving sprocket without changing the position of the lever, and has a spring interposing between and connecting the separated crack shaft and the driving sprocket. The spring generates a difference in force between the weight of a rider and pedaling to switch the positions of a shaft and a sprocket, and generate a difference in angle, wherein the generated difference in angle physically changes gears.
