Title: Robot controller
Inventor: IWATANI MASAHIRO
IPC: B25J19/06
Filed: 1986-01-16
Abstract: PURPOSE:To prevent drop of shafts of an industrial robot due to misoperation by inputting the state of a brake releasing switch to a control part to detect the misoperation of the brake releasing switch. CONSTITUTION:When a main switch 30 is turned on, a control part 21 starts the operation. If a brake releasing switch 31 is closed at this initial time, this closing of the switch 31 is displayed on a display part 36 with a signal LOCK turned on. An operator finds the misoperation by this display and opens the brake releasing switch 31. The control part 21 does not output a PWM control signal to a motor driver 24 until the brake releasing switch 31 is opened. Thus, the misoperation of the brake releasing switch 31 is eliminated completely. Thus, drop of shafts of the robot due to careless brake release is prevented.

Filed: 1990-01-16
Abstract: PURPOSE:To improve the service life of refractory brick of tuyere part in a low cost by executing heat insulation to gap between the tuyere and the refractory brick with graphite sheet. CONSTITUTION:A graphite sheet pipe 13 is formed by winding the graphite sheet or multi-layers of thin graphite sheets. This graphite sheet pipe 13 is fitted to outside of single pipe 11 and double pipes 12 for the tuyere, respectively and closely brought into contact with the refractory brick 5. By this method, rapid temp. distribution is not developed in the refractory 5 around the tuyere, and crack in the refractory brick 5 is not developed and breakage caused by spalling can be prevented. Since the end face 13-1 of the opening in the graphite sheet pipe 13 has high resistance to the chemical reaction, the reaction rate with molten steel or blowing gas is low. Further, since the heat conductivity to longitudinal direction of the graphite sheet pipe 13 is high, the heat absorption from the outlet side of the tuyere is high, and the growth of mushroom 15 developed at the end face of the opening in the tuyere is promoted by synergistic effect with cooling gas. Therefore, the erosion of the end face of the opening in the tuyere is reduced.
