    • An electric power converter comprising a plurality of reactors, a plurality of self quenching type switching elements, the reactors and switching elements being series-connected per one arm, and surge-absorbing snubber circuits connected in parallel to the switching elements respectively, the switching circuits being driven by gate drive circuits connected to respective gates of the switching elements to thereby convert a DC voltage into an AC voltage or convert an AC voltage into a DC voltage. The electric power converter further comprises: an apparatus for recovering energy accumulated on at least one side of the reactors and the snubber circuits and an apparatus for generating a DC source for supplying electric power to each of the gate drive circuits, on the basis of the recovered energy. In the electric power converter constituted by a plurality of self quenching type semiconductor switching elements connected in series, high efficiency is attained through reduction in size of the gate driver and electric power saving.

    • A connector device is provided which can be made small and thin in a form as close to the external width dimension of an information processing medium per se as possible. A frame member for guiding an IC pack and connector section to be connected to the IC pack are mounted on a housing plate member. An ejection mechanism for the IC pack is incorporated on the housing plate member. The ejection mechanism is equipped with guide portion so as to operate the ejection mechanism. An operation unit is arranged in a width direction of the housing plate member so as to be slidable in a direction intersecting with that in which the IC pack is inserted and withdrawn. A stopper is provided in the width range of the housing plate member 2 such that it can prevent a movement of the slide plate member in the withdrawing direction and allows a movement of the operation unit in the withdrawing direction when the operation unit is released.
    • 提供一种连接器装置,该连接器装置可以尽可能靠近信息处理介质的外部宽度尺寸而形成为小而薄。 用于引导IC组件的框架构件和连接到IC组件的连接器部分安装在壳体板构件上。 用于IC封装的弹出机构装在外壳板件上。 弹出机构配备有引导部,以便操作弹出机构。 操作单元布置在壳体板构件的宽度方向上,以便能够沿与IC组件插入和抽出的方向相交的方向滑动。 在壳体板构件2的宽度范围内设置有止动件,从而能够防止滑动板构件在退避方向上的移动,并且允许操作单元被释放时使操作单元沿取出方向移动。

    • A header device for receiving an IC card or pack, comprises a housing, which includes an IC-pack holder having an opening through which the IC pack is inserted into and removed from the housing, and a pair of first levers projecting into the IC-pack holder so as to abut an end portion of the IC pack, and a pair of second levers located outside the holder. The first and second levers are coupled to each other at their respective proximal ends, so that they are immovable relative to each other. The coupled levers are rotatably mounted on the housing. If the IC pack is inserted into the housing through the opening, the end portion of the IC pack pushes the respective first levers, thereby rotating both the first and second levers in a first rotation direction. Then, if the second levers are rotated in a second rotation direction reverse to the first rotation direction, the first levers push the IC pack out of the housing.
    • 一种用于接收IC卡或包装的头部装置,包括一个壳体,它包括具有一个开口的IC包装保持器,IC封装通过该开口被插入壳体中并从壳体中移除;以及一对第一杠杆,突出到IC- 以便与IC封装的端部抵接,以及一对位于支架外部的第二杠杆。 第一和第二杠杆在它们各自的近端处彼此联接,使得它们相对于彼此是不可移动的。 联接杆可旋转地安装在壳体上。 如果IC封装通过开口插入壳体中,则IC封装的端部推动相应的第一杠杆,从而沿第一旋转方向旋转第一和第二杠杆。 然后,如果第二杠杆沿与第一旋转方向相反的第二旋转方向旋转,则第一杠杆将IC包推出壳体。

    • A printer has a pair of frame panels that support the ends of a carriage guide shaft, a carriage that carries a print head, a carriage drive motor, and first and second pulleys on which a belt connected to the carriage is mounted. The first and second pulleys limit the range of bidirectional carriage movement so that the maximum width of carriage movement is substantially equal to the width between the pair of frame panels. A tube that carries ink to the print head is disposed curving in a U-shape in the direction of the width between the pair of frame panels. The carriage drive motor is disposed in the space in which the tube is located in the space on the opposite side as the direction in which the tube curves, and the drive shaft of the carriage drive motor is perpendicular to the scanning plane of the carriage.
