Title: Continuously variable transmission
Inventor: BITO HIROMICHI
IPC: F16H9/18
Filed: 1987-08-14
Abstract: PURPOSE:To automatically vary a speed change characteristic at the time of the acceleration and deceleration of an engine by automatically varying the spring force of a governor spring for energizing a servo valve toward a fly weight side in accordance with engine speed. CONSTITUTION:At the time of increasing engine speed, a turning force is transmitted to a driving shaft 1, a servo spring 8, a servo valve 6, and a fly weight 5 while, on the other hand, it is also transmitted to a rigid pulley 3a and a sleeve 11 causing the weight 5 to integrally rotate while being slightly delayed with respect to the driving shaft 1 due to inertial force. Hence, the spring force of the spring 8 is weakly set enabling the movement in the axial direction of the valve 6 to be quicker and increasing the speed change ratio between a driving side and a drive side, to suppress the rotating speed of an accessory to be low. And, at the time of lowering engine speed, the weight 5 is integrally rotated while being slightly advanced with respect to the driving shaft 1. Hence, the spring force of the spring 8 is increased increasing the moving speed of the valve 6 in the direction of the fly weight and reducing the speed change ratio between the driving side and the driven side, to set the rotating speed of the accessory to be high.

IPC: G06T7/60
Filed: 1994-08-26
Abstract: PURPOSE: To provide a linear component extracting method which can stably extract a straight line as an object of extraction at a high speed. CONSTITUTION: When a scanning range is determined, the mean value of pixel density of pixels on the straight lines connecting a peak point and respective opposite points is found while the opposite points corresponding to the peak point are shifted, pixel by pixel, from one end to the other end of the scanning range, and the mean value is regarded as an image information value. Then when the scanning of the opposite point in the scanning range ends, straight lines to be found are extracted from image information values of the respective straight lines. Consequently, even when the object of extraction is low in contrast, the straight line as the object of extraction can stably be extracted at a high speed only through the processing for finding the mean value of pixel density of the pixels on the straight lines connecting two points on a circumference.
