    摘要： An operation confirming method capable of making, in order to enhance an operation program correction efficiency, an operation path at an operation confirming time (teaching mode) identical with that at an actual job time (play mode) as much as possible; and a control device therefor. The method comprises the steps of inputting respective shaft operation instruction values (&ohgr;j) based on an actual operation speed to a mechanical simulator-carrying low-speed instruction converter (7), and instructing to a servo controller unit (4) a quantity (&ohgr;ij) (=&ohgr;sj/P), obtained by dividing an output (&ohgr;sj) from the mechanical simulator by a specified positive real number P at the low-speed instruction converter, as respective shaft operation values N times (N; maximum natural number not exceeding the real number P).

    摘要： A positioning servo controller is provided in which optimization of the positioning state can be conducted simply by adjusting an adjustment gain. In a positioning servo controller with: a speed feedforward controlling section (22) which sets a value that is obtained by adding a first feedforward compensation amount to a position deviation, as a speed command; an acceleration feedforward section (23) which sets a value that is obtained by adding a second feedforward compensation amount to a speed deviation, as an acceleration command, the second feedforward compensation amount being obtained by amplifying a differential value of the first feedforward compensation amount; and a torque amplifier (3) in which an acceleration deviation is used as a torque command, and which drives a controlled object on the basis of the torque command, the values of the first feedforward gain and the second feedforward gain are values of functions in which the value of the adjustment gain is used as an argument.

Respective control parameters P[p] (p=0, 1 - - - ), arranged in the order of gradually increasing a chance of oscillating the servo control system, are set sequentially starting with P[0], a torque command Tr or a fluctuation amount &sgr;, showing a variation in frequency component of vibration of a speed feedback amount &ohgr;, is determined for each of control parameters, and the servo control system is assumed to have reached an oscillation criticality when a fluctuation amount exceeds a specified value to thereby reset a control parameter set at that time to P[p−q] (q; natural number) or to P[0].

    摘要： Prior to welding together two overlapped plated steel sheets 4 and 5 by laser lap welding that irradiates parts of the plated steel sheets (4, 5) extending on a weld line (Lw), slits (4b) are formed intermittently in the upper plated steel sheet (4) with a laser beam (L). Subsequently, a welding head (1) is moved along the weld line (Lw) while the upper plated steel sheet (4) is pressed against the lower plated steel sheet (5) by pressure rollers. Parts of the upper plated steel sheet (4) extending on the weld line (Lw) and not provided with the slits (4b) are irradiated with the laser beam to laser-weld the plated steel sheets (4, 5) together. A vapor of the component of the coating layers coating the joining surfaces (4a, 5a) of the plated steel sheets (4, 5) produced from the coating layers by the heat produced by the laser beam is discharged through the slits (4b). After thus laser-welding together the plated steel sheets (4, 5), the slits (4b) of the upper plated steel sheet (4) are stopped with a molten metal produced by melting a filler with the laser beam.

    摘要： An object of the present invention is to provide a rotor of a fluid machine in which the rotor can be made light in weight and moment of inertia of the rotor can be reduced and the rotor can be easily balanced in its rotating direction. In this rotor of a fluid machine, a fluid is compressed and pumped by a pair of rotors engaged with each other. A hollow portion is formed within a tooth stripe portion of one rotor. A thickness forming portion for a balance correction is formed in an opening portion of this hollow portion to balance the rotor in its rotating direction and is projected on an inner circumferential side of the hollow portion.

    摘要： A spindle motor comprises a stationary shaft, a rotor hub rotatably mounted by ball bearings to the stationary shaft, and annular sealing members disposed between the outer surface of the stationary shaft and the inner side of the rotor hub axially outwardly of the ball bearings. The sealing member is directly fitted onto the outer race of the corresponding ball bearing. The outer race of each ball bearing is high precision finished so that the sealing member is definitely coaxial with the stationary shaft regardless of the finishing accuracy on the inner side of the rotor hub. Accordingly, the radial distance between the inner side of the sealing member and the outer surface of the stationary shaft can be minimized with high precision offering an excellent labyrinth effect.
