A machine tool is provided with a base, a tool rest and a boring bar magazine. The tool rest is mounted on the base and retains a boring bar. The tool rest is moved in a first direction in parallel with an axis of the main spindle and in a second direction perpendicular to the first direction. The magazine is located opposite to a headstock and stocks the boring bars and swivels and indexes the boring bar. The tool rest is moved whereby the boring bars are changed by other ones between the tool rest and the magazine. Thus, the tool rest is moved in at least two directions so that the boring bars are changed between the tool rest and the magazine.

A PDP apparatus in which degradation in image quality such as display missing points does not occur, even if the peak luminance is increased, has been disclosed. In the PDP apparatus, the display load ratio of each subfield is detected and a sustain pulse cycle is changed according to the display load ratio of each subfield. Moreover, an adaptive sustain pulse number change means is provided, which calculates the total amount of variations in time by summing the variations in time in a display field caused by the changes in the sustain pulse cycles and increases/decreases the number of sustain pulses of each subfield according to the total amount of variations in time.

A method of driving a display panel, and a panel display apparatus, in which displays do not lack realism even when power control is performed, have been disclosed. In the display panel driving method, the display frame for a screen is comprised of plural subframes, each being assigned a number of times discharge for light emission is performed according to the specified luminance relation, the representation with gray scale is performed by combining the subframes that display according to the intensity of the input image signal for each cell, and the power consumption is controlled by both the control of the total number of times discharge for light emission is performed of the display frame and the control of the gain of the input image signal.

A method of displaying a dynamic halftone image on a display panel made of pixels divides each frame of the image into subframes and turns on and off the subframes. The method includes the steps of finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame, counting the number of pixels in the line, selecting corrective pulses, which turn on/off corresponding subframes to enable/disable corresponding intensity levels, according to the counted number and a change in the specific intensity levels between the frames, and adjusting original display signals for the pixels in the line according to the corrective pulses, respectively. The method eliminates halftone disturbance and false color contours from the image even if the moving speed of the image on the display panel is high.

A stage apparatus of the present invention includes a plurality of interferometers 14H, 14J, 14R for measuring the displacements of a fine adjustment stage 11 at respective measuring sites, a plurality of actuators 29h, 29j, 29r for independently moving the stage 11, and a mathematical operational conversion unit 43. Deviations .DELTA.H, .DELTA.J and .DELTA.R are derived by a subtracting displacements H, J, R of the stage 11 actually measured by the interferometers from the target displacements HT, JT, RT of the stage 11, and supplied to the mathematical operational conversion unit 43, where the target driven increments .DELTA.h, .DELTA.j, .DELTA.r are derived by a calculation using a predetermined mathematical model (this model is an inverse matrix T.sup.-1, which is the inverse of the matrix T describing the operation for deriving the displacements measured by the interferometers from the displacement produced by the actuators). The rotational speed controllers 39A, 39B, 39C of the actuators are driven by the amounts h, j, r that correspond to the target driven increments .DELTA.h, .DELTA.j, .DELTA.r. This results in a reduced effect of any mechanical interference, so that the positioning of the fine adjustment stage 11 can be quickly achieved with high accuracy.

In a stage-drive controlling device used in a scanning projection exposure apparatus, a targeted speed Iwy is imparted to a speed control system for controlling the speed of a substrate stage, and a targeted speed Irc is concurrently imparted to a speed control system for controlling the speed of a mask stage such that the two stages assume a predetermined positional relationship. A deviation Xrc in the speed of the Speed control system is multiplied by 1/4 (multiplied by the magnification of projection) by a deviation feedback system, and the multiplied value is fed back as a targeted input to the speed control system. For this reason, the following formula holds: Ywy={Kwy/(s+Kwy)}.times.(Yrc/4). If the response of the speed control system side (substrate stage side) is good, even if the speed response of the speed control system side (mask stage side) is poor, the speed ratio between the two stages is kept at 4:1.
