| 20120121350 | DRILL HAVING MULTIPLE FLANKS - A drill capable of suppressing inter-layer peeling (delamination) while keeping hole diameter accuracy even if the number of holed to be worked increases is provided. The drill includes a first flank which has a ridge line forming a cutting edge, a second flank which is adjacent to the first flank and has a ridge line forming a land portion, and a third flank which is adjacent to the first flank and has a ridge line forming a chisel edge. The drill further includes a fourth flank which is surrounded by a ridge line forming the first flank, a ridge line forming the third flank, and a trough line forming the second flank | 05-17-2012 |
| 20110010006 | ROBOT CONTROL SYSTEM - A robot control system has a portable operating device TP and a robot control device RC. The portable operating device TP is actuated by a rechargeable secondary battery and used to operate a robot R. The robot control device RC is capable of wireless communication with the portable operating device TP and performs automatic operation of the robot R based on teaching data provided by the portable operating device TP. The robot control system causes an emergency stop of the robot R when the wireless communication between the portable operating device TP and the robot control device RC is interrupted. The robot control system further includes a charging device CU, a connection monitoring section | 01-13-2011 |
| 20090309531 | SERVO MOTOR MONITORING APPARATUS - Disclosed a servo motor monitoring apparatus including: a magnetic pole position calculating member to extract a magnetic pole position signal of the servo motor from a motor drive line connected to the servo motor; a present position signal inputting member to receive an input of a present position signal from the position detecting member attached to the servo motor; and a monitoring member to compare operations of the servo motor based on two types of signals of the magnetic pole position signal and the present position signal of the servo motor, and to output a stop instruction signal for cutting off a power supply to the servo motor when detecting disagreement. | 12-17-2009 |
