IPC: B02C18/08
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a grinder capable of maintaining the center of gravity of a rotating part during grinding and capable of reducing the vibration of the whole device. SOLUTION: A crushing blade 8 is pivotally supported in freely rotatable state with a shaft part 15 as the center at the tip of a roller chain 7 mounted to a rotary shaft 5 in a crushing chamber 4. A shaft part 15 being the rotation center of the crushing blade 8 and the center position of gravity of the crushing blade 8 are made to be coincided so that the gravity center balance of the rotary part may not collapse even if tip crushing blade 8 is rotated with a supporting point as the center during grinding. In such a way, the gravity center balance of the rotary part is maintained and the vibration of the whole device is reduced even if the crushing blade 8 is varied with own supporting point as the center during grinding.

Title: Processing method for extracting moving object
Inventor: SHIO AKIO
IPC: H04N7/32
Filed: 1991-10-01
Abstract: PURPOSE:To stably extract a moving object even when a complex density change exists in the background of objects and many moving objects exist by subtracting a background image from an input image to remove the influence of the background and executing labeling processing to extract the areas of moving objects. CONSTITUTION:An image processing part 400 finds out a background image by a mode filtering method based on N input images stored in an input image memory 510 and stores the background image in a background image memory 520. Then the processing part 400 finds out a difference image between a successively inputted input image and the background image and stores the difference image in a difference image memory 530. Then threshold processing is applied to the difference image and a ternary area image is found out and stored in an area image memory 540. Then the contents of the memory 540 are inputted, the labeling processing of the contents is executed and the existing positions of the moving object areas and the number of the areas are found out and transferred to a host computer 600. The adoption of the mode filtering processing method is caused by a reason that the passage of a moving object is ignored when its frequency is not low.
