Title: Cutter plate and cutting tool for machining
Inventor: VILLA STEFANO
IPC: B23C5/10
Filed: 2001-03-27
Granted: 2002-08-21
Abstract: A cutter plate, in particular a spherical face milling cutter, is provided for a cutting tool, and is made of a hard metal and has four wings with cutting edges. The cutting body, which is cruciform in a view from the front, has cutting edges, which extend from the area of the circumference of the cutting tool as far as its axis of rotation, or at least close to it. A simple clamping device, for example a clamping claw, is sufficient for fastening the cutting body on the tool body. The cutting body provides a distribution of the forces acting on one or several wings to all wings, in particular during interrupted cutting, wherein not all the cutting edges of the cutting body are in simultaneous contact with the workpiece, so that a good force transfer to the tool body is possible. The cutting body can be assembled from two individual cutter plates, which are plugged together.

Title: Image reading device and method for the same
Inventor: HATASE TAKAYUKI
IPC: H04N5/335
Filed: 2001-12-07
Granted: 2003-08-01
Abstract: When an image object is read using a camera including a line sensor having pixels arrayed in a line, a relative-movement-detecting section detects a movement of a transfer head holding the object in X direction relative to the camera. The detecting section outputs a movement-detecting signal to a camera-controller every time the object moves a given distance corresponding to a scanning space in X direction. The camera-controller controls a pixel-selecting circuit according to the movement-detecting signal and outputs an image signal from pixels selected based on pixel-selecting information. As a result, even if a moving mechanism of the transfer head has an error, a resolution becomes stable and an exact image is obtainable.
