    摘要: Protrusions, serving as reference marks for indicating reference positions at which reel strips (106) are to be applied, are provided on three unillustrated reel frameworks. Marks for registration purpose to be aligned with the respective protrusions are provided individually on the respective three reel tapes. At least two reel strips differ in relative position, with respect to a spinning direction of the reels, between the mark and symbols on the reel strips. When the reel frameworks are stopped at rotation detection positions defined by unillustrated sensors, positions of respective symbols on rotation paths defined between the reel frameworks corresponding to at least two reel strips are shifted from each other in the spinning direction of the reels.

    摘要: When the amount L of actual load change that is picked up from an external plant control device exceeds a reference level L* of load change amount per prescribed unit time that is pre-set to serve as an impact drop detection level, the d axis field current Id is suppressed to a prescribed limiting amount. The d axis voltage reference Vd* and hence the motor and armature voltage Eac are thereby suppressed exclusively during a prescribed field limiting period Td. A large potential difference (voltage margin) is thereby generated between the converter output voltage Vac and AC motor armature voltage Eac, thereby speeding up the rise of output current of the motor. Subsequent recovery of the motor speed after impact drop is speeded up by returning the voltage level to the original d axis voltage reference Vd*.

    摘要: A game machine has an input section through which a player inputs various instructions necessary for the play. The input section also displays various kinds of game information and performs computation of the score. The machine also has a mechanical section which includes a tank having a transparent wall and filled with water, a plurality of balls suspended in the water, a central tubular structure for creating a central upward flow of water, a liquid supply portion including a nozzle under the tubular structure, and an information reading unit disposed in a peripheral region of the tank through which the balls fall down due to, for example, difference in the specific gravity between the ball and the water. A rotary guide rail is disposed in the peripheral region so as to catch the falling balls. Any ball which leaves the lower end of the guide rail is received by the information reading unit, on condition that the lower end of the guide rail opposes the information reading unit at the very moment at which the ball leaves the lower end of the guide rail. Specific information peculiar to the ball is read by the information reading unit which has a magnetic sensor. The player is allowed to visually observe the state of shuffling of the ball by the circulating water, as well as the state of the balls entering the information reading unit.

    摘要: According to this invention, there is provided a motor control apparatus comprising a field weakening device for converting a velocity feedback signal obtained from the rotational speed of a motor into a secondary magnetic flux reference signal by using a field pattern, a field pattern selector for comparing a predetermined signal with a q-axis torque current reference signal obtained on the basis of the secondary magnetic flux reference signal converted by the field weakening device, the velocity feedback signal, a velocity reference signal, and a torque reference signal, and outputting, on the basis of the comparison result, a control signal for switching the field pattern, and a field pattern storage section for switching, on the basis of the control signal output from said field pattern selector, the field pattern to be used in the field weakening device. Since the selector can switch the field pattern, an accurate torque output can be realized.

    摘要: A video game machine has a mechanism extracting balls, a display unit having a display area which displays a matrix composed of boxes, and a CPU. The CPU implements a function enabling the player to appoint a ball type in terms of color and number to boxes of a second line of the matrix. A function is provided for automatically displaying, in the first and third lines of the matrix, ball marks correlated to the ball marks displayed in the second line, such that the color sequences of the ball marks in the first and third lines are the same as that in the second line and such that numerals greater and smaller by one than a numeral in a box of the second line appear in the third and the first lines in each column of the matrix. Further provided is a function for determining whether or not the numeral of the extracted ball coincides with the numeral of any ball mark on the display and a function for changing the mode of display of the box having the coincident numeral. Also provided is a function for determining whether any line, column or oblique diagonal line of the matrix is completed by boxes displayed in the changed display mode. Finally, a function is implemented for instructing the machine to pay medals when any line is completed.
