Title: Developing device
Inventor: YOSHIDA KEIICHI
IPC: G03G15/08
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which autonomously adjusts the conveyance amount of a developer irrelevantly to the deviation direction of the developer and holds the balance of the amount of the developer constant. SOLUTION: A balance 84 which can slant corresponding to the deviation of the amount of the developer is provided before the place where the developer flows in a fin 81. While the developer deviates to a side F, the amount of the developer scooped up onto a separator 8 also deviates to the side F, so a force pressing the balancer 84 deviates and the balancer slants toward α. Consequently, the amount of the developer flowing on the separator 8 is large on the side F and small on a side R, so the amount MA of the developer carried to the side R by the fin 81 is larger than the amount MB of the developer carried to the side F by a conveyor screw 9, so that the developer having deviated to the side F is returned to the side R.

IPC: G06T7/60
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To make accurately measurable the weight of a livestock such as a pig without giving a stress to the livestock using a non-contact method. SOLUTION: A dustproof box 5 is mounted to a ceiling 3 of a pigsty near a projector 2, and a light source where a lattice fringe slide is fitted and a video camera are installed in the dustproof box 5. When light is projected from the projector, a lattice fringe 13 is projected to the body surface of a floor 11 and a pig 12. The image is captured by the video camera. Based on the deviation of the lattice fringe 13 in the captured image, the body height (H) of the pig 12 is obtained. Also, a black-and-white binarization processing is made to the captured image to obtain a projection area (A) of the pig 12. The relationship among the body height (H) of the pig 12, the projection area (A), and the weight (W) is closely expressed by W=aH<b> A<c> .  Further, the weight (W) is calculated by using the body height (H) and the projection area (A) since the order (d=b+2c) of the multiple regression expression is close to that (d=3) of the volume.
