Abstract: A front panel 11 has a plurality of caulking pieces 16 each of which is formed in a tongue-like shape defined by a pair of slits 17 in a side edge portion 11c of the front panel. The caulking piece is inwardly bent at its base end portion 16a and bent sideward at its distal end portion 16c to form a substantially L-shape. Side panels 12 whose forward end portions are abutted on an inner face 11a of the front panel 11. The side panels are formed along the forward end portions 12a with caulking holes 18 into which the caulking pieces 16 are adapted to be engaged. The front panel 11 is joined to a mount panel 2 in substantially intimate contact along its whole surface. The front panel 11 and the mount panel 2 are formed into an integral structure, whereby the mechanical strength in a direction of the thickness of the front panel can be maintained.

Abstract: In a shield case for housing an electronic equipment therein, a plurality of metal plates include a top plate, a bottom plate, a front plate, a rear plate, a pair of side plates, which are assembled to one another in a box-like shape. A projection is formed on an outer face of the rear plate. A stopper projection is formed on an outer face of each side plate. A rear face holding piece extends downwardly from a rear edge of the top plate. The rear face holding piece is formed with a holding member at a lower end portion thereof. The holding member elastically abuts on the outer face of the rear plate, after climbing over the projection. Side face holding pieces extend downwardly from side edges of the top plate. Each side face holding piece is formed with a notched portion at a lower end portion thereof. The notched portion includes a guide groove for receiving the stopper projection in accordance with the rearward movement of the top plate when the holding member climbs over the projection, and an engagement groove extending forward from an upper end of the guide groove, for engaging with the stopper projection in accordance with the forward movement of the top plate when the holding member abuts on the outer face of the rear plate after climbing over the projection.

Abstract: The present invention provides a dynamic model parameter identification system consisting of a parameter classifying part and a motion planning part. The parameter classifying part approximates the respective links forming the manipulator by means of a symmetrical and homogeneous virtual solid link, calculates the inertial parameters, and finally classifies the calculated inertial parameters into parameter groups. The motion planning part calculates the condition number for the parameter coefficient sub-matrix, and calculates the number of equilibriums which is shown by the quotient of the maximum and minimum values of the vector normal of the rows of the coefficient sub-matrix. The motion planning section then sets the motion for parameter identification so that the condition number and number of equilibriums are both below predetermined values. Therefore, it is possible to identify the dynamic parameters of a robotic manipulator with a high degree of accuracy and without carrying out numerous trial-and-error experiments.

Abstract: An actuator which carries a magnetic head of a disk memory seeks a track on the disk by being actuated by a pair of trapezoidal drive currents, which have no or less power spectrum at the frequency coinciding with the mechanical resonance frequency of the positioning mechanisms. A trapezoidal waveform whose ratio of an upper side to a bottom side is adjusted depending on seek stroke. The mechanical resonance frequency may be within the range of the power spectrum of the trapezoidal drive currents so long as it coincides with the characteristic frequency with a zero power spectrum. A constant velocity region which has no current flowing into the actuator between the first positive trapezoidal current and the second negative trapezoidal current is provided when the seek stroke is long.
