摘要： A numerical controlling unit includes: an inputting part into which a machining program is inputted; an analyzing part that analyzes the machining program to generate an instructed spindle rotational speed and calculates a spindle load ratio of a load applied to a spindle under a machining condition according to the machining program to a spindle load caused when the workpiece is machined: and a distributing part that generates, based on the machining program, a distribution amount per unit period inputted into a feed-axis servo driver. A spindle-rotational-amount-command outputting part receives the instructed spindle rotational speed and outputs a spindle-rotational-amount command for commanding a rotational amount per unit period which is inputted into a spindle driver. A cutting-load-for-judgment calculating part calculates a reference torque value based on the spindle load ratio, the distribution amount, and the spindle-rotational-amount command. A spindle-load comparing part compares the reference torque value with a load torque value which is feedback inputted by the spindle driver and outputs a tool-breakage detecting signal when the load torque value is higher than the reference torque value.

摘要： A small light-weight thin film magnetic head apparatus for a rigid disk or a floppy disc. The apparatus includes a magnetic head formed directly on a distal end of a suspension as a thin layer, one end of the suspension being supported by an arm. This magnetic head is very small-sized and light-weight and has a head gap in direct contact with a recording medium, increasing the recording density and the read/write speed. Because of its reduced weight of the thin film magnetic head, a remarkably improved degree of followability with respect to the recording medium can be achieved. A method of manufacturing this magnetic head apparatus is also disclosed.

摘要： In a servo-system of a conventional numerical control (NC) device, a delay in response or deformation is always observed on an output side with respect to an inputted speed command or position command and an actual output response behaves differently from a command value. Such delay or deformation of the output response constitutes a significant problem particularly in case of controlling one object simultaneously by a plurality of servo-system, which results in a remarkable defect in a controlling performance. According to this invention, when a transfer function of a servo-system of the type comprising a control system and a control object is designated by W, a device or a signal conversion system with an inverse function 1/W of the transfer function W is located a a pre-compensation system in advance of the control system thereby to input a speed or position to be controlled into the pre-compensation system. Thus, according to this invention, the output response to the inputted speed or position command can fully follow up, and moreover, in a system provided with a plurality of servo-system, the respective servo-system can be controlled with substantial no delay in response, so that it is possible to precisely control one object. Particularly, in a case where the servo-system of this invention is utilized for an NC device for a machine tool, a working operation with no working error can be realized especially in an arc cutting operation.
