    • [Problem] To provide a check valve and a diaphragm pump employing the same which has a good response, and in which a valve chamber can be made small so as to be hardly influenced by bubbles. [Means for Solution] A check valve includes a valve chamber 11 which is defined by a top wall 8 having an introducing port 8a of a fluid, a bottom wall 9 having an exhaust port 9a of the fluid, and a side wall, and a valve body 12a which is supported in the valve chamber 11 in a cantilever manner having its base end fixed to the side wall and its distal end formed as a free end, the valve body being arranged above the introducing port 8a. The bottom wall 9 is formed with a valve seat 9b having an inclined face 9b2 which is inclined so as to be gradually separated from the top wall 8 along the valve body 12a from the base end toward the distal end thereof. When the valve body 12a in the cantilever shape moves between the top wall 8 and the valve seat 9b, the valve body 12a is restricted by the valve seat 9 having the inclined face 9b2, at opening and closing operation of the valve body 12a, whereby a moving amount of the valve body 12a becomes smaller, and response time from an open state to a closed state becomes shorter.
    • [问题]提供一种具有良好响应的止回阀和采用该止回阀的隔膜泵,并且其中可以使阀室较小以致几乎不受气泡影响。 [解决方案]止回阀包括阀室11,其由具有流体的引入口8a的顶壁8,具有流体的排气口9a的底壁9和侧壁限定, 以及阀体12a,其以悬臂方式支撑在阀室11中,其底端固定在侧壁上,其远端形成为自由端,阀体布置在引入口8a的上方。 底壁9形成有具有倾斜面9b2的阀座9b,倾斜面​​9b 2从顶壁8的底端朝向顶端部8逐渐与上壁8分离。 当悬臂形状的阀体12a在顶壁8和阀座9b之间移动时,阀体12a由具有倾斜面9b 2的阀座9限制,在开启和关闭操作时 阀体12a,阀体12a的移动量变小,从打开状态到关闭状态的响应时间变短。

    • The diaphragm is supported by the frame at the outer edge thereof. The pair of terminal members is mounted on the frame, and a pair of lead wire drawn from the voice coil is fixed to the land portion of the terminal member for electrical continuity. Since the land portion is disposed on the upper side of the frame, fixation of the lead wire can be performed without turning the frame upside down. This simplifies the manufacturing process of the speaker and also prevents a breakage of the lead wire that conventionally happens when the frame is turned upside down. Further, this prevents the operator from touching the lead wire since no part of the lead wire is exposed outside the frame after the fixation.
    • 隔膜由框架在其外边缘处支撑。 一对端子构件安装在框架上,并且从音圈引出的一对引线固定到端子构件的陆部以进行电连续性。 由于接地部设置在框架的上侧,所以可以在不使框架上下颠倒的情况下进行引线的固定。 这简化了扬声器的制造过程,并且还防止了当框架被颠倒时通常发生的引线的断裂。 此外,这防止了操作者接触引线,因为在定影之后没有引线的一部分暴露在框架外部。

    • By forming a flange portion (16a1) protruding inward in the radial direction at an upper end portion (16a) of a voice coil (16), a coiling sectional shape of the voice coil (16) is set to a L-shape. And, the upper end portion (16a) of this voice coil (16), is bonded and fixed to a central flat portion (12b) of a diaphragm (12). Hereby, by only increasing slightly the weight of the usual voice coil having an I-shaped coiling section, the large bonding area can be obtained between the voice coil (16) and the diaphragm (12), so that separation of the voice coil (16) can be prevented. Further, since other portions of the voice coil (16) than the upper end portion (16a) thereof have the usual coil thickness, it is not necessary to expand the width of a cylindrical magnetic gap G in a magnetic circuit unit (18), whereby it is prevented that electroacoustic conversion efficiency of a speaker (10) lowers.
    • 通过形成在音圈(16)的上端部(16a)沿径向向内突出的凸缘部(16a1),将音圈(16)的卷绕截面形状设定为L字形。 并且,该音圈(16)的上端部分(16a)被接合并固定在隔膜(12)的中央平坦部分(12b)上。 因此,通过仅轻微地增加具有I形卷绕部分的通常音圈的重量,可以在音圈(16)和隔膜(12)之间获得大的接合面积,使得音圈 16)。 此外,由于音圈(16)的其他部分比其上端部分(16a)具有通常的线圈厚度,所以不需要在磁路单元(18)中扩大圆柱形磁隙G的宽度, 从而防止扬声器(10)的电声转换效率降低。

    • A new can top structure is provided in a can containing beverage liquid therewithin. On the can top, a ring serving as a jig for forming an opening therein is attached by way of a rivet at the center thereof. The ring has a pull side free end and a push side free end. There is also formed a tear-out portion defined by a scored line in the can top and the push side free end of the ring overlaps part of the tear-out portion. Since the ring is oriented slantwise with respect to the tear-out portion, the ring stays out of the way at the time of consuming the beverage liquid even though the pull side free end of the ring is erected to cause the push side free end to drive part of the tear-out portion into the can such that an opening is formed.
    • 在其中含有饮料液体的罐中提供了一种新的罐顶结构。 在罐顶上,用作在其中形成开口的夹具的环通过铆钉在其中心附接。 环具有拉动侧自由端和推侧自由端。 还形成有由罐顶部的刻痕线限定的撕出部分,并且环的推侧自由端与撕出部分的一部分重叠。 由于环相对于撕出部倾斜定向,所以即使在环的拉动侧自由端竖立以使推侧自由端在 将撕开部分的一部分驱动到罐中,使得形成开口。
