Title: Method and device for processing of three-dimensional image information
Inventor: TAKEUCHI RYOZO
IPC: G06T15/00
Filed: 1987-12-15
Abstract: PURPOSE:To shorten the time required for transformation of 3-dimensional image information to a display image by describing only the movable part of the 3-dimensional image information in 3-dimensional vector image information. CONSTITUTION:A pair of 3-dimensional image information obtained by recording a static part as pixel image information and a movable part as the 3-dimensional vector image information respectively can be set and displayed freely in terms of said movable part by a shift/rotation command received from an operating part. In this case, the static part occupying the most of a 3-dimensional image is not processed and only the movable part undergoes coordinate transformation through a coordinate transforming part 25 and pixel information image transformation processing through a pixel information transformation processing part 26 respectively. Thus all pieces of 3-dimensional image information are recorded in the 3-dimensional vector image information. Thus a display image is obtained in an extremely short time compared with a conventional system where the coordinate transformation and the pixel picture information transformation processing are required for all pieces of information.

Title: Collision detector for movable unit
Inventor: MORI MASAHIKO
IPC: B23Q5/58
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a technical means for reducing the damage of work or machine as much as possible when collision has occurred at the time of moving a movable unit at a high speed, especially for a technical means for the emergency stop of the movable unit such as a machine tool or a conveyer when an abnormal load caused by collision, etc., is exerted upon this unit. SOLUTION: Two kinds of high and low overload detection levels are provided and when a low-speed moving command is outputted from an NC device, a high overload detection level 40 is automatically set but when a high-speed moving command is outputted, a low overload detection level 41 is automatically set. It is more preferable that the lower side overload detection level 41 is stepwisely or continuously changed corresponding to the commanded moving speed. When the movable unit collides, its impulse shows the result adding its kinetic energy and driving energy proportional to the output torque of a servo motor 12 in case of collision. Since the kinetic energy is proportional to the square law of speed, the overload detection level 41 is set low so as to cancel the increase of this kinetic energy.
