Title: Precognition device for abnormality of tool
Inventor: DATE OSAMU
IPC: B23Q17/09
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the apprehension of drill breakage even during slight feed of a main spindle due to inertia by providing a coupling means to make a tool fitting shaft free from a sleeve body in both axial and rotational directions when resistance acting on the tool fitting shaft exceeds its set value. CONSTITUTION:When a damaged or wrongly selected drill and clogging chips increase resistance acting on a tool fitting shaft 8 above its fixed value during machining process, a ball 12 leaves a recess 14 formed on the protruding part 13 of the shaft 8, which can not follow the rotation of a member 4 to cause an exhaust hole 25 to get out of the position of a communicating hole 27 for shutting off the exhaust hole 25. The above-mentioned shutting off causes pneumatic pressure in an air feed passage to rise rapidly, and a pressure sensor detects the above-mentioned rapid pressure rise to input the signal of the pressure rise into a control amplifier and then into the control part of a machining center for stopping a main spindle 2 and simultaneously giving the alarm of an abnormal state. In addition to that, the shaft 8 is made free from the rotary member 4 in both axial and rotational directions simultaneously with the occurrence of the abnormal state, and therefore moves back to check the action of torque or thrust load on itself even during the continuous rotation or feed of the main spindle 2. Thus the breakage of a drill can be prevented.

Title: Satellite capturing apparatus
Inventor: NISHIKAWA KUNITOSHI
IPC: G01S3/42
Filed: 1994-04-19
Abstract: PURPOSE:To search and capture the direction of a satellite in a short time and surely when the direction of the satellite is unknown. CONSTITUTION:When the direction of a satellite is unknown, a control means 16 observes an elevation-angle amplitude obtained from an elevation-angle monopulse signal while the azimuth angle of an array antenna 11 is being changed by an antenna drive means 17. At a point of time when the elevation- angle amplitude exceeds a first prescribed threshold level, the azimuth-angle direction of the satellite is captured. Even when the elevation-angle deviation of the array antenna 11 with reference to the satellite is comparatively large, the azimuth-angle direction of the satellite is captured surely at a point of time when the azimuth angle of the array antenna 11 coincides with the direction of the satellite. The elevation-angle direction of the satellite is captured by observing an azimuth-angle amplitude obtained from an azimuth-angle monopulse signal while an elevation angle is being changed by keeping the azimuth angle of the array antenna 11 definite after the azimuth-angle direction of the satellite has been captured. At a point of time when the azimuth-angle amplitude exceeds a second threshold level, the elevation-angle direction of the satellite is captured.
