摘要： A vibration device with a simple structure, in which a yoke and a coil are combined, is incorporated in a game machine control device, and caused to vibrate in response to displays on the screen of a game machine. This structure allows vibrations to be transmitted to a player who is gripping the control device, and therefore, the player can be given the effect of the sense of touch in compliance with the displays.

摘要： The invention concerns with a system for controlling a stepping motor, and more particularly with a stepping motor control system which moves a head of a disk drive unit with (1-2)-phase excitation. With the stepping motor controlling system, a driving force is produced to rotate the stepping motor by a predetermined angle with the (1-2)-phase excitation for ech step pulse supplied from the exterior, and step pulses with a plurality of cycles are used to make the stepping motor rotate at different speeds depending on the cycles of the step pulses. In that controlling system, a time period of the 1-phase excitation is changed depending on the pulse interval of the step pulses, thereby reducing a level of noisy sounds like seek noise.
摘要翻译：本发明涉及一种用于控制步进电机的系统，更具体地涉及一种利用（1-2）相激励来移动磁盘驱动单元的磁头的步进电机控制系统。利用步进电动机控制系统，产生驱动力以使步进电动机以（1-2）相激励方式从外部提供的呃步脉冲旋转预定角度，并且使用具有多个循环的步进脉冲以使步进电机根据步进脉冲的周期以不同的速度旋转。在该控制系统中，1相激励的时间段根据步进脉冲的脉冲间隔而改变，从而降低诸如寻道噪声的噪声等级。
