摘要： A submersible pump comprising: a discharge casing open at the bottom thereof; a motor case fixed inside the discharge casing and containing therein a motor for driving an impeller; a support plate positioned so as to close an opening of the discharge casing for supporting the motor case; a downwardly concaved pump casing placed under the support plate for defining a pressure chamber between it and the support plate; and a downwardly concaved strainer placed under the pump casing for defining a suction chamber between it and the pump casing is disclosed. In this submersible pump, the discharge casing has an increased-diameter stepped flange integrally formed along the periphery of the opening of the discharge casing. Within a stepped portion of the stepped flange there are sequentially mounted respective peripheral portions of the support plate, of the pump casing, and of the strainer. The discharge casing and the support plate are fastened together by first bolts vertically extending therethrough, and in that the support plate, the pump casing and the strainer are fastened together by second bolts vertically extending therethrough. By this arrangement, the entire pump can be easily assembled by fastening the first and second bolts.

摘要： A pump casing manufactured by press forming of steel plate and including a volute casing encircling a pump impeller so as to form a fluid path around the pump impeller is disclosed. The cross-sectional area of the fluid path is gradually increased towards a discharge port of the pump casing. The pump casing includes a casing body which is formed at first by press forming a metal plate into a cylindrical cup shape having an opening portion at one side thereof and a closed bottom portion at the other side of the same, and then by press forming the cylindrical cup shaped casing body so as to have a volute portion radially outwardly expanded from a cylindrical surface of the casing body at an axially intermediate portion thereof which radially opposite to the pump impeller, a casing flange outwardly extending from the opening portion and an aperture serving as a suction port at the bottom portion.Since no separate volute member is provided within the pump casing to form the volute portion, the outer diameter of the pump casing can be made small and also the shape of the fluid path in the volute casing can be made smooth.

摘要： In a submerged pump of a type having a pump casing in which a cylindrical motor casing is housed, the pump casing and the motor casing are constructed in such a way that the pump casing is given the shape of a polygonal column and the motor casing substantially inscribes the inner surface of the respective walls of the pump casing. The space defined by the adjacent inscribing lines and the portions of the walls between the lines is adapted to pass water without creating spiral flow therethrough from a discharge port of the volute chamber toward the discharge opening of the pump.

摘要： Tilt of an optical disk is detected and controlled by detecting a tilt zone border based on a zone correspondence table expressing a ZCLV zone of the optical disk and the tilt zone including a border corresponding to the border of the ZCLV zone. The deterioration of accessibility within the ZCLV zone at the time of tilt control is reduced by the tilt zone having a border corresponding to the border of the ZCLV zone.

摘要： There is provided a control circuit for arithmetically processing at least one of focus-directional and tracking-directional position error signals, and adding the arithmetic operation result as an input amount to a coil for driving in the opposite direction. The control circuit produces such a control signal as to cancel the effect of an oscillation mode of an objective lens holder. An output determination circuit temporarily restricts functions of the control circuit when the determination circuit has determined that a disturbance component is mixed in the position error signal. Thereby, even in the case of slight displacement, the objective lens can be controlled independently in the focusing and tracking directions while avoiding interference movement in both directions.
摘要翻译： 提供了一种用于对聚焦方向和跟踪方向位置误差信号中的至少一个进行算术处理的控制电路，并将算术运算结果作为输入量加到用于沿相反方向驱动的线圈。 控制电路产生这样的控制信号，以消除物镜支架的振荡模式的影响。 当确定电路已经确定在位置误差信号中混合了扰动分量时，输出确定电路暂时限制控制电路的功能。 因此，即使在轻微位移的情况下，可以在聚焦和跟踪方向上独立地控制物镜，同时避免在两个方向上的干涉移动。

摘要： A pump casing made of sheet metal comprises a casing jacket having a cylindrical cup shape, an end plate formed at one side of the casing jacket, a casing flange formed at the other side of the casing jacket and a projecting portion radially outwardly bulged so as to have a volute shape. The end plate is axially outwardly bulged so as to have an arcuately curved surface, and the base portion of the projecting portion is located on the extension of the arcuately curved surface of the end plate so as to provide continuity from the end plate to the projecting portion. With the above structure, there is no portion where a great deal of bending stress caused by stress concentration is generated, and the pump casing has a sufficient strength and rigidity against not only piping forces but also internal pressure.

摘要： A centrifugal pump casing of a centrifugal pump, includes a casing shell accommodating a rotary impeller therein and having as a basic circle an inner peripheral circle having a diameter greater than the diameter of the outer peripheral circle of the impeller. A bulged portion bulged radially outwardly is integrally formed on the outer peripheral wall of the casing shell, the bulged portion extends from a starting point remote from the winding starting point of the casing shell in a circumferential direction to an end point while gradually increasing in height in the direction from the starting point to the end point. A pipe-like discharge nozzle is connected with the casing shell so that it extends between the end point where the bulged portion is highest and the winding starting point where no bulged portion is formed. In this arrangement, since the bulge height above the basic circle is not so great even at the end point where a maximum height is reached, the bulged portion can be formed through only one pressing process without the need for an annealing process. Further, since the difference in height between the end point where the bulged portion is highest and the winding starting point where no bulged portion is formed is not so great, the wall portion of the casing shell at the winding starting point can serve as a guide; and accordingly, a guide for discharge water which is required in the prior art may be eliminated.
摘要翻译： 离心泵的离心泵壳体包括容纳旋转叶轮的壳体壳体，其具有作为基本圆的直径大于叶轮的外周圆直径的内周圆。 在壳体外壳的外周壁上形成有径向向外凸出的鼓出部，凸出部从远离壳体的卷绕起点的起点向圆周方向延伸至端点，同时高度逐渐增加 从起点到终点的方向。 管状排出喷嘴与壳体壳体连接，使得其在凸出部分最高的终点与没有凸起部分的卷绕起始点之间延伸。 在这种布置中，即使在达到最大高度的终点处，基础圆上方的凸起高度也不是很大，所以可以仅通过一个挤压工艺形成凸出部分，而不需要退火工艺。 此外，由于凸出部分最高端点与没有凸起部分的卷绕起点之间的高度差不大，所以绕组起始点处的壳体壳体的壁部分可以用作引导件 ; 因此，可以消除现有技术中所需的排水指导。
