A feature point calculating device 21 calculates feature points with a sequence of input coordinate points. A symmetrical axis alternative calculating device 22 references the feature points and calculates symmetrical axis alternatives. A first determination symmetrical axis determining device 23 extracts the most horizontal symmetrical axis alternative and the most vertical symmetrical axis alternative from the symmetrical axis alternatives calculated by the symmetrical axis alternative calculating device 22. A first symmetry input point set calculating device 24 calculates symmetry determination segments of one of the horizontal and vertical symmetrical axis alternatives. A first symmetrical axis distance calculating device 25 calculates the distance between the center point of each symmetry determination segment and the symmetrical axis alternative. A first symmetry determining device 26 calculates a deviation of the calculated distances. When the deviation does not exceed a predetermined threshold value, the first symmetry determining device 26 determines that the input figure is line symmetrical to the symmetrical axis alternative. A symmetrizing process device 27 compensates the input figure so that sets of input coordinate points calculated by the first symmetry input point set calculating device 24 become line symmetrical to the symmetrical axis alternative.

A graphic form recognition apparatus which can extract a singular point of a curved line portion precisely is disclosed. The apparatus comprises a coordinate point string reading section for reading in a string of coordinate points of a graphic form of lines inputted from an inputting apparatus, a storage apparatus for storing the string of coordinate points thus read in, a distance thinning out or deletion section for thinning out or deleting points of the string of coordinate points at a fixed distance, an elevation angle calculation section for calculating angles of elevation provided by the remaining coordinate point string, an elevation angle most frequent value calculation section for calculating a most frequent value which appears most frequently among all of the thus calculated angles of elevation, a difference calculation section for calculating differences between the angles of elevation and the most frequent value, and a recognition section for recognizing each coordinate point, at which the difference of the angle of elevation from the most frequent value is higher than a predetermined value, as a singular point of the inputted graphic form of lines.

A tire cord fabric suitable for reinforcement of rubber articles is disclosed. The tire cord fabric is manufactured by lengthwisely arranging a great number of cords as warp cords over a given width and then relatively coarsely interlacing them with weft yarns. In each selvage portion of the fabric is formed a joint part consisting of a special cord arrangement.

A spring prime mover unit comprising a spring prime mover, a transmission gear and a plurality of connectors. Among the connectors, there are rotatable connectors and non-rotary connectors. The rotatable connectors are the ends of some shafts of the transmission gear and the non-rotary connectors are the attachments of a covering frame. The spring prime mover unit may be exchangeably equipped with auxiliary toy parts or toys which have not prime movers and form various movable toys to one prime mover unit. Therefore, children themselves can assemble various interesting movable toys and enjoy various motion of the toys.

In an apparatus for controlling an air/fuel ratio of a general-purpose internal combustion engine using mixed fuel containing alcohol and gasoline and operated at a desired engine speed inputted by the operator while a throttle opening is regulated such that a detected engine speed converges to the inputted desired engine speed, a fuel injection amount prepared for mixed fuel is increased/decreased when a load is kept constant and the output air/fuel ratio (at which an output of the engine becomes maximum) is estimated. A rate of alcohol contained in the fuel is estimated from the estimated air/fuel ratio and the fuel injection amount is corrected based on the estimated alcohol rate, thereby determining the fuel injection amount appropriately in accordance with the estimated alcohol rate.
摘要:
In an apparatus for discriminating a piston stroke of a general-purpose internal combustion engine connectable to an operating machine to be used as a prime mover of the machine and having a four-stroke operating cycle comprising intake, compression, expansion and exhaust, the operating cycle is discriminated based on intake air temperature detected by an intake air temperature sensor whether a stroke next to a predetermined crank angular position at which a crank angle sensor produces an output is the intake stroke or the expansion stroke, when operation of the engine is determined to be under a stable condition. With this, it becomes possible to discriminate the four-stroke operating cycle of the general-purpose engine without using an expensive pressure sensor.

In a blade vortex interaction (BVI) noise reduction system for a helicopter a rotor blade, a tab is movable via an actuator from a first position, wherein the tab is within the blade, to a second position, wherein the tab extends outwardly from a trailing edge of the rotor blade. The actuator is operated so that the tab advances and retreats in response to rotating timing of the rotor blade, to reduce the BVI noise of the rotor blade.
