20120003054 | TAP WITH DRILL AND METHOD FOR CUTTING INTERNAL THREAD - A tap with drill includes a drill portion including a plurality of chip discharge grooves and having drill blades for cutting a prepared hole. The tap further includes a tap portion for cutting the internal thread on an inner circumferential surface of the prepared hole formed by the drill blades, and oil holes. The tap with drill is applied for performing cutting work. The drill blades and thread cutting edges include three blades formed along chip discharge grooves, respectively. The oil holes are helically formed in three with the same leads as the chip discharge grooves and opened at relief surfaces of the drill blades, respectively. The chip discharge grooves straddle the drill portion and the tap portion in fixed groove sectional shapes and have negative lands swelled into grooves. | 01-05-2012 |

20150100151 | REMOTE HANDLING APPARATUS FOR LOAD OBJECT AND AUXILIARY APPARATUS THEREOF - A remote handling apparatus includes a joystick device, a load lifting device and a counterforce controller. The joystick device includes a counterforce generator that generates operation counterforce via a stick that accepts manual operation. The counterforce controller includes a pulsed counterforce controller and/or a deviation counterforce controller. The pulsed counterforce controller calculates a time rate of change of a dynamic load value of the load object, and outputs a counterforce command signal indicating a counterforce command value for generating pulsed counterforce. The deviation counterforce controller calculates a deviation amount of a dynamic load value from a static load value, and outputs a counterforce command signal indicating a counterforce command value for generating a counterforce. Embodiments may be implemented as an auxiliary apparatus, which is attached to an existing remote handling apparatus. | 04-09-2015 |
