摘要:
In a database, variety of modules which can be used as constituent elements of the object of design are registered as parametrized models, and instance generating information representing a procedure of generating instances and feature estimation information representing a method for estimating design features are stored every abstraction level for the various modules. A floorplan oriented design is executed by means of the database. That is, even at the higher level of the behavior or RT level, by means of the database, the design features of each module to be used for the design are estimated and the floorplan is executed. On the basis of the execution result, the design features of the circuit scale, delay time, power consumption and so forth of the object of design are estimated, and it is decided whether or not a design change is required.

A magnetic head slider assembly for a magnetic disk type recording/reproducing apparatus includes a slider body, a floating pad provided on the slider body and projecting beyond a disk facing surface thereof, a thin film layer disposed at one end of the slider body, a magnetic head constituted by the thin film layer as an integral part thereof, and a core pad projection incorporating therein a core of the magnetic head and projecting beyond an adjacent disk facing surface of the slider body. The core pad projection is not formed as a continuation of the slider body and is separated from the floating pad a predetermined distance longitudinally of the slider body by a recess interposed therebetween whereby the core pad projection is positioned closer to the magnetic disk than a back end of the floating pad whereby influence of a process offset between the slider body and the magnetic head during fabrication process can be eliminated.

An automobile has a body 1 and a hood 2. In the body 1seats 1B and 1C are arranged, and four sides (left, right, rear and upper) around the seats 1B and 1C are open. The hood 2 is separate from the body 1 and is integrally formed. The hood 2 is formed by a transparent member, and is mounted (or dismounted) freely on the body 1. The hood 2, when mounted, encloses the four sides of the seats. Preferably, the hood 2 is formed from polycarbonate resin.

A magnetic head device has a magnetic head slider by means of which information is recorded in and read from a magnetic recording medium. The magnetic head slider is supported by a supporting structure having an internal cavity, an opening formed in a portion of the structure where the magnetic head slider faces the magnetic recording medium and communicating with the internal cavity, and a gas passage through which the gas introduced into the internal cavity through the opening is discharged to the exterior of the internal cavity. With this arrangement, the pressure acting on the back surface of the magnetic head slider is adjusted to keep the slider afloat, while removing dust suspended in the gas around the recording medium and the supporting structure.

A magnetic head slider for use with a magnetic recording medium has a bearing surface which opposes to the magnetic recording medium and generates a pneumatic bearing effect for floating the magnetic head slider above a surface of the magnetic recording medium. The bearing surface includes a tapered surface portion constituting an air entrance and a flat rail portion connected to the tapered surface portion. The magnetic head slider has vent holes formed in the flat rail portion penetrating through the magnetic head slider from the flat rail portions to an end surface of the slider opposite to the magnetic recording medium.

A head-slider. The head-slider includes a magnetic-recording head and an air-bearing surface. The air-bearing surface includes air-bearing portions, shallow-recessed surfaces, and a deep-recessed surface. Air-bearing portions are configured to fly nearest to a magnetic-recording disk; shallow-recessed surfaces have a first depth from the air-bearing portions; the deep-recessed surface has a second depth, larger than the first depth, from the air-bearing portions. Air-bearing portions and shallow-recessed surfaces are configured to generate positive pressure; and, the deep-recessed surface is configured to generate negative pressure. A shallow-recessed surface is disposed near a leading edge of the head-slider; air-bearing portions are preceded and abutted by the shallow-recessed surface; a plurality of small leading-end pads are disposed near a leading edge, and at least at each side of the shallow-recessed surface near lateral sides, of the head-slider; and, a leading-end deep-recessed surface is disposed at a leading side of the leading-end pads.

In a motor-driven power steering apparatus, there are provided a reference output characteristic memory previously storing a reference output characteristic expressing a corresponding relation between a driving current of an electric motor and an output torque corresponding to the driving current, a correction coefficient computing circuit computing a ratio TO/TM between an output torque TM of the electric motor detected at a time of applying a predetermined current M to the electric motor, and an output torque TO corresponding to the driving current IM in the reference output characteristic as an output correction coefficient. A current control computing unit calculates a corrected current control signal by multiplying a current control signal of the electric motor computed on the basis of a steered condition of a vehicle by the output correction coefficient, and outputs a drive control signal based on the corrected current control signal to a motor driving unit.
