    摘要: A spindle apparatus of a machine tool comprises a main spindle rotatably supported in a housing via bearings. A helium circulation system is provided for introducing helium, lower in density and fluid pressure than air, through a helium supply port into a gap on the outer periphery of the main spindle within the housing, and for discharging helium to the outside through a helium discharge port. The main spindle is rotated in an atmosphere of the helium. The spindle apparatus is simple in structure, but can minimize the power loss of the main spindle and reduce the motor power, and also gives a cooling effect.

    摘要: A slip control system for a torque converter with a lockup clutch comprises a controller from which a slip control signal is outputted to a slip control actuator of the torque converter. The controller is arranged to calculate a reference value of a lockup clutch engagement pressure on the basis of a characteristic of the torque converter, to calculate a difference canceling lockup clutch engagement pressure for adjusting an actual slip rotation speed to the target slip rotation speed, to obtain the sum of the lockup clutch engagement pressure reference value and the difference canceling lockup clutch engagement pressure as a lockup clutch engagement pressure command value, and to output the control signal indicative of the lockup clutch engagement pressure command value to the actuator.

    摘要: A control system for controlling a lock-up clutch of a torque converter employed in an automatic transmission of a vehicle, the lock-up clutch being controllable by a pressure differential between apply and release pressures comprises a detector for detecting a demand of change (decrease/increase) in the pressure differential, a pressure-differential setting circuit for setting a target pressure differential in response to the demand of change in the pressure differential, and a pressure-differential filter having a desired dynamic characteristic and being responsive to the target pressure differential for outputting a filtered pressure-differential command value via a filtering process based on the desired dynamic characteristic. A pressure-differential regulation circuit is connected to the pressure-differential filter for receiving the filtered pressure-differential command value as an input information data to generate an output indicative of a duty ratio to be output to a lock-up solenoid valve and for regulating the pressure differential in accordance with the duty ratio.
