摘要： A screw pump includes a housing and a pair of intermeshing screw rotors. An end face of the rotor adjacent to an inlet port of the housing is provided with an inlet opening. Each rotor has a first portion whose lead angle changes. The first portions and the housing cooperate to form an inlet space. During rotation of the rotors, communication between the inlet space and the inlet port is blocked by the first portions and the housing thereby to form a closed pump space adjacent to the inlet space. Volume of the pump space is set smaller than the maximum volume of the inlet space. A closure member is provided which covers at least a part of the inlet openings. The closure member closes the inlet space when the volume of the inlet space exceeds that of the pump space.

摘要： An ignition coil includes primary and secondary coils, center and outer cores, and an ion current detector for transmitting an ion current detection output. The center core has an axial upper end defining a center core upper end surface. The outer core has an axial upper end defining an outer core upper end surface. The center core upper end surface axially protrudes upwardly relative to the outer core upper end surface. The center core upper end surface is located at a stagger distance axially from the outer core upper end surface. The stagger distance is defined such that a detection period for residual magnetic noise in the ion current detection output falls within a system requirement period of a control unit.

摘要： In a stick coil, there is disclosed an ignition coil for an internal combustion engine which can prevent a crack (a collar leak) from being generated due to a thermal stress. In this ignition coil, the structure is made such that a size (L) of a portion which is in parallel to an axial direction of a primary spool (121) in a projection portion (121b) is larger than a size (T) of a portion which is in parallel to an orthogonal direction to the axial direction of the primary spool (121). Accordingly, a frontal projected area of the projection portion (121b) as seen from a flowing direction of a resin becomes small, a resin flow is hard to get out of order at a time when the resin flows through a portion corresponding to the projection portion (121b) at the forming time, and a convoluted void and a weld are hard to be generated. Accordingly, since it is possible to prevent a mechanical strength in a root portion of the projection portion (121b) from being reduced, it is possible to previously prevent a crack from being generated in the root portion of the projection portion (the collar portion) (121b) due to a thermal stress so as to reduce an insulating property.
摘要翻译：在棒状线圈中，公开了一种用于内燃机的点火线圈，其可以防止由于热应力而产生裂纹（轴环泄漏）。在该点火线圈中，该结构被制成使得与突起部分（121b）中的初级线轴（121）的轴向方向平行的部分的尺寸（L）大于与主卷轴（121）的轴向的正交方向平行的部分。因此，从树脂的流动方向看，突出部分（121b）的正面投影面积变小，在树脂流过与突起部分相对应的部分时，树脂流动难以变得不顺利（121b），并且难以产生卷积的空隙和焊缝。因此，由于可以防止突起部（121b）的根部的机械强度降低，所以能够防止在突起部（轴环部）的根部产生裂纹，（121b）由于热应力而降低绝缘性能。

摘要： A screw rotor is for use in a screw pump that pumps fluid by rotation of a pair of screw rotors engaged with each other in a rotor housing. The screw rotor includes a multiple-thread portion for pump suction side and a single-thread portion for pump discharge side. The screw rotor is formed so that the tooth profile of the multiple-thread portion is connected to the tooth profile of the single-thread portion through a boundary plane that is perpendicular to the rotation axis of the screw rotor. The first curved portion coincides with the third curved portion in the boundary plane.
