Title: Spindle protecting structure for spindle through coolant
Inventor: KATSUSAWA YUKIO
IPC: B23Q1/00
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent coolant from intruding into a spindle or spindle motor even if a plenty of coolant is leaked from a coolant supplying section for spindle. SOLUTION: Coolant is supplied to a hollow hole 10 provided on a spindle or a shaft 9 which is connected with the spindle, through a fixed side part 23 and a rotary side part 22 of a rotary joint 3, and the shaft 9 is provided with an elastic seal part 34 on the peripheral. Coolant leaked from the seal part 34 is flown out by a flinger 33. If a plenty of coolant is leaked from this coolant supplying section, the flinger 33 cannot exhaust a plenty of coolant. However pressure of an air room 31 is increased due to leaked coolant, and the seal part 34 is pressed against the shaft 9 by this pressure, so that coolant cannot intrude into the air room 32. Thereafter coolant supply is stopped. With such a structure, when a plenty of coolant leaks, the seal part prevents coolant from intruding into the spindle or spindle motor, temporarily.

IPC: H02P7/00
Filed: 2001-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a motor drive circuit wherein motor control excellent in response can be implemented without need for any special signal for switching from power saving mode to operating mode. SOLUTION: The state of a motor control ECU 3 is switched from power saving mode to oscillation stabilization wait mode according to the first level change (from L-level to H-level) in driving control signal PS. For the mode to switch from oscillation stabilization wait mode to operating mode, a time (20 milliseconds in this case) corresponding to the oscillation rise time of an oscillator 14 is required. If the inputted driving control signal PS is at the H-level when the mode is switched to operating mode, the motor control ECU 3 sets a timer to 20 milliseconds and starts clocking. If there is level change (from H-level to L-level) in driving control signal PS when the value on the timer is 30 milliseconds, the signal is recognized as the first pulse signal with a pulse width of 30 milliseconds.
