    摘要： A staple forming mechanism having at least first and second configurations. The staple forming mechanism including a bend surface having a first surface width in the first configuration and a second surface width in the second configuration for forming staples having first and second crown sizes, respectively. The forming mechanism also includes at least two side portions spaced apart by a first former width in the first configuration and by a second former width in the second configuration. The side portions cooperate with the bend surface to form the staples. A stapler includes the forming mechanism and a driver including a driving surface having a first driver width in the first configuration and a second driver width in the second configuration for driving the staples of the first and second crown sizes into a stack of papers.

    摘要： A powered stapler includes a housing and a stapling engine within the housing. The stapling engine includes a staple driving assembly and a rotational drive train operable to actuate the staple driving assembly. A stack height compensation mechanism is integrated with the rotational drive train of the stapling engine and is distinct from any portion of the housing. The stack height compensation mechanism is operable to enable the stapling engine to compensate for varying stack heights of sheets to be stapled by the powered stapler.

    摘要： Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. Conventionally, an antenna of the cavity-backed slot-radiating type comprises a slot formed in an end of an electrically conductive enclosure, which slot may be energised by a radiating element in registration with the slot. A feed network may connect to the radiating element via a transmission line formed by a conductive track on a feed layer located between the enclosure and an electrically conductive cover. A slot is formed in the section of the cover that covers the end of the cavity in which a slot is formed, such that the two slots are of substantially the same size and shape. A problem with this structure is that the cavity is difficult to mould in one piece and it can be difficult to achieve alignment of respective slots; as a result it is relatively costly to manufacture. Also, it is difficult to insert dielectric material into the enclosure to adjust the performance parameters of the antenna. An antenna according to an embodiment of the invention employs an enclosure having an aperture in one end; in preferred arrangements the aperture provides the enclosure with a substantially open end, over which the cover is placed. The cover has a slot therein, of a smaller size than the size of the aperture presented by the open ended enclosure and the slot in the cover then acts as the radiating slot. The benefit is that it is then easier to insert dielectric material into the enclosure and the enclosure is easier to mould in one piece, leading to a potential cost reduction.

    摘要翻译： 本发明的实施例涉及一种天线结构，并且特别适用于阵列天线。 通常，空腔支撑的槽辐射型天线包括形成在导电外壳的端部中的槽，该槽可以由与槽对准的辐射元件激励。 馈电网络可以经由位于外壳和导电盖之间的馈电层上的导电轨道形成的传输线连接到辐射元件。 在覆盖形成有狭槽的空腔的端部的盖的部分中形成槽，使得两个狭槽具有基本上相同的尺寸和形状。 这种结构的问题是，腔难以一体成型，难以实现各槽的对准; 因此制造成本相对较高。 此外，难以将介电材料插入外壳以调整天线的性能参数。 根据本发明的实施例的天线采用在一端具有孔的外壳; 在优选的布置中，孔为外壳提供了基本上开口的端部，盖子放置在该开口端上。 该盖在其中具有狭槽，其尺寸小于由开放式封闭体所呈现的孔的尺寸，然后盖中的狭缝用作辐射槽。 其优点在于，将电介质材料插入外壳更容易，并且外壳更容易模制成一体，从而降低潜在的成本。
