When graphics computations are to be performed to calculate the display data of a figure to be drawn within a frame that is formed of a plurality of lines in accordance with input vector data, the present invention reduces the storage capacity of a RAM to which a work area for storing intermediate data is allocated. When the graphics computations are to be performed, the frame in which the figure is to be displayed is segmented into a plurality of drawing areas for each of the lines. As regards the work area for storing the intermediate data, the same work area is allocated to all the drawing areas. The graphics computations for calculating the intermediate data of the individual drawing areas are sequentially performed by repeatedly using the same work area.

An electrolytic capacitor according to the present invention employs a capacitor element wherein an anode foil having an anode internal terminal and a cathode foil having a cathode internal terminal are wound or laminated through a separator. The end of the anode foil faces with the cathode foil through the separator and the surface area of the cathode internal terminal is provided with an enlargement treatment, whereby the small area portion of the cathode foil that faces with the anode foil is eliminated, and the charge/discharge characteristics are thus improved. Furthermore, in the electrolytic capacitor provided with the capacitor element wherein the anode foil having the anode internal terminal and the cathode foil having the cathode internal terminal are wound or laminated through the separator, the capacitor element being impregnated with an electrolyte, the cathode internal terminal is composed of an aluminum material, the surface of the cathode internal terminal is etched and the concentration of iron in the etching layer is less than 300 ppm.

A stepping motor uses a low-cost ferrite magnet instead of an expensive rare-earth magnet. The stepping motor has characteristics equivalent or superior to those of a conventional stepping motor. The stepping motor is provided with a rotor, a stator yoke, and bearingsandwhich rotatably hold the rotorwith respect to the stator yoke. The rotorhas a columnar shape and has plural magnetic poles arranged in the circumferential direction of the outer circumferential surface. The stator yokehas an outer cylindrical portion and an inner circumferential portion which surrounds the rotorand which has plural first pole teeth and plural second pole teeth. The outer diameter 'd' of the rotorand the outer diameter 'D' of the stator yokeare set so that the ratio of &#x201c;d/D&#x201d; is greater than 0.6.

The present invention provides a polarizable electrode for an electrical double layer capacitor which has good high-temperature storage characteristics and can prevent a decrease in electrostatic capacity and increase in internal resistance, and also provides an electrical double layer capacitor using the electrode. A polarizable electrode is formed by mixing Ketjen black, active charcoal and a polytetrafluoroethylene (PTFE) aqueous solution. An etched aluminum foil is used for the collector, and this etched aluminum foil is dipped in a phosphoric acid aqueous solution or an ammonium phosphate or other phosphate aqueous solution to thereby retain 15 to 115 mg/mof phosphorus on the surface of the etched aluminum foil. The electrostatic capacity per unit area on the surface of this etched aluminum foil is 50 to 350 &#x3bc;F/cm.

In a die bonding apparatus with a position correcting stage that has a die carrying surface upon which a die is placed by a collet, the external circumferential shape of the die carrying surface of the position correcting stage is formed so as to be smaller than the external circumferential shape of the die to be carried on the die carrying surface, thus avoiding damages to the surface of the die.

To assure the continuity of bonding by preventing any buckling of a covered wire or slipping-off of the covered wire from a second clamper, the second clamper is caused to vibrate while a capillary and first clamper are being raised to a ball formation level after the first clamper is closed and the second clamper is opened in the step of raising the capillary and first clamper to the ball formation level, thus preventing the covered wire from sticking to the second clamper.

Method for wire-bonding a covered wire

To prevent melting and scattering of a covering-film during ball formation, the covering-film, at the time a ball is formed, has been completely removed from the portion of a covered wire which corresponds to the tail length that protrudes from the tip of a capillary.

A device for conveying a wafer ring between a wafer ring container and a pellet pick-up device. A pair of guide rails which guide both side edges of a wafer ring that is conveyed by a wafer ring conveying assembly are installed pivotally in a vertical direction near the wafer ring cassette. The guide rails are pivoted so as to take a horizontal position when the conveying of the wafer ring is performed and take a vertical position when the pellet pick-up device is in operation. Thus, the operation of the pellet pick-up device is not hindered by the guide rails.
