IPC: G03G15/00
Filed: 1990-05-23
Abstract: PURPOSE:To set the value of a current which flows in a corona discharger by fuzzy inference by calculating a belonging degree to the set of controlled variable from the belonging degree to the set of the detected quantity of state according to respective rules and inferring the controlled variable having the highest possibility so that a device may be controlled. CONSTITUTION:A CPU 81 controls the respective component devices according to a control program stored in a ROM 82. Then, ambient humidity is measured by a humidity sensor 60 and, at the same time, the density of an original is detected, for example, by the surface potential sensor 61 of a photosensitive drum. By using the data, the belonging degree to the fuzzy set of the controlled variable is calculated from belonging degree to the fuzzy set of the quantity of state according to the respective fuzzy rules, and next the sum-set of the sets belonging to the respective rules is calculated, then the controlled variable having the highest possibility is calculated by obtaining the centroid of the sum-set. The obtained centroid is set as the value of the current of an output which is supplied to an external electrostatic charger. Thus, the value of the current which flows in the corona discharger is set by the fuzzy inference.

IPC: G06T17/00
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To determine whether the display of a polygon nomination exists on the basis of a display area of a polygon. SOLUTION: The display area of a polygon on a bird's eye view display screen is calculated to display a polygon nomination for the polygon with the display area thereof exceeding a specified value. As a result, the nomination is displayed for the polygon displayed in a bird's eye view with the area thereof exceeding a specified value to allow the checking for the name of the polygon without scrolling the bird's eye view display screen by stopping a vehicle at each time. In addition, no nomination is displayed for a polygon existing away from the vehicle with the area thereof smaller than the specified area. This eliminates the display of unnecessary nominations with a lower importance thereby facilitating the visual recognition of roads at a long distance and other information with a higher importance.

Abstract: PURPOSE:To reduce the size of an apparatus by bundling notes in one direction by a bundling means, then turning the same 90 deg. by a rotating stand and a pivot without carrying them to another place and thereafter bundling on the spot the notes again in another direction crossing the first one, thereby effecting a crosswise bundling of the notes. CONSTITUTION:The superposed notes A sent to a bundling portion 3 are interposed and pressed between a pressing plate 312 and a fixed plate 311 by moving the pressing plate 312 upwardly for making a bundle thereof in one direction in as-pressed condition and then the pressing plate 312 moves downwardly to decompress the note A'. Next, a ball screw 420 in a rotating mechanism 41 turns to upwardly move a rotating stand 411, whereby the notes A' are raised above the upper surface of the pressing plate 312 and, at the same time, a shaft 435 of a pivot mechanism 43 is rotated to downwardly move a pivot 431 for pressing the upper surface of the notes A'. In this condition, the notes A' are rotated 90 deg. by the rotating stand 411 and the rotating stand 411 and the pivot 431 move back to the original positions. Upon completion of 90 deg. rotation of the notes A', the pressing plate 312 rises again to make a crosswise bundling by winding a strip B. With this simple construction, the reduction of the size of apparatus and speed-up of bundling operation can be achieved.
