    • Embodiments of the present invention help provide a simple and inexpensive actuator mechanism for a magnetic disk drive. The actuator mechanism includes an approximately circular coil and a simple shaped magnet, and is capable of displaying adequate performance required for the magnetic disk drive. According to one embodiment, the magnetic disk drive includes an actuator mechanism which has an approximately circular coil and an approximately rectangular magnet. The long axis direction of the rectangular magnet is oriented in parallel to a straight line connecting the center of the inner circle of the circular coil in a state in which the actuator is positioned at the outermost circumference of a data area and the center of the inner circle of the circular coil in a state in which the actuator is positioned at the innermost circumference of the data area.

    • In a ladder-type piezoelectric filter, attenuation in stop bands on a low frequency side and a high frequency side are increased while a pass band is widened. The ladder-type piezoelectric filter is made up by alternately connecting parallel arms and series arms. The parallel arms are respectively made up by serially connecting parallel resonators and LC element networks, and the series arms are respectively made up of series resonators. The LC element networks are respectively made up so as to be inductive in resonant frequencies of the serially connected parallel resonators. Further, the LC element networks include capacitors which contribute to formation of a new series resonant point in the stop band on the high frequency side.
    • 在梯型压电滤波器中,在通带被加宽的同时,在低频侧和高频侧的阻带的衰减增加。 梯型压电滤波器由交替连接平行臂和串联臂组成。 并联臂分别由并联谐振器和LC元件网络串联连接,串联臂分别由串联谐振器构成。 LC元件网络分别构成为串联连接的并联谐振器的谐振频率的电感。 此外,LC元件网络包括有助于在高频侧的阻带中形成新的串联谐振点的电容器。

    • An image forming apparatus for forming an image on a recording medium is disclosed. The image forming apparatus includes a print head (4) having an ink emitting surface (6) in which there are formed a plural number of ink emitting openings (13). An ink is emitted from the ink emitting openings (13) for forming an image on a recording medium. The image forming apparatus also includes an emission controller (41) for controlling the ink emission from the ink emitting openings (13) formed in the ink emitting surface (6). The emission controller (41) is responsive to an input image signal to control the quantity of preliminary ink emission from one or more of the ink emitting openings (13) or to select one or more of the ink emitting openings (13). In this manner, the quantity of the preliminary ink emission from the ink emitting openings (13) is controlled, or one or more of the ink emitting openings (13) is selected, responsive to the image signal, to diminish the wasteful ink emission and to clean the ink emitting openings (13) or the vicinity without damaging the ink emitting surface (6).
    • 公开了一种用于在记录介质上形成图像的图像形成装置。 图像形成装置包括具有油墨发射表面(6)的打印头(4),其中形成有多个喷墨口(13)。 从用于在记录介质上形成图像的墨排出口(13)发出墨。 图像形成装置还包括用于控制从形成在墨水发射表面(6)中的墨水发射开口(13)的墨水排出的排放控制器(41)。 排放控制器(41)响应于输入图像信号来控制来自一个或多个喷墨孔(13)的初步墨水排放量,或者选择一个或多个喷墨孔(13)。 以这种方式,根据图像信号控制从油墨排出口(13)发出的预备油墨的量,或者选择一个或多个喷墨孔(13),以减少浪费的油墨排放, 以清洁墨水排出口(13)或附近,而不会损坏墨水发射表面(6)。
