摘要： PROBLEM TO BE SOLVED: To provide a high-pressure pump capable of suppressing erosion of an electromagnetic drive part.SOLUTION: A fixed core 72 is provided in the inside of the diameter of a coil 71. A movable core 73 to be provided to the suction valve side of the fixed core 72 moves the suction valve in either the open-valve or close-valve direction. Second springs 22 accommodated in the first storage chamber 61 of the fixed core 72 and the second storage chamber 62 of the movable core 73 biases the movable core 73 to the suction valve side. A guide pin 80 so formed as for it to have higher hardness than the fixed core 72 locks each of the second springs 22 at a depth of the first storage chamber 61. The guide pin is capable of suppressing the occurrence of erosion on the inner wall of the first storage chamber 61 due to the collapse of cavity generated in the fuel of the first storage chamber 61 attributed to the reciprocal movement of the movable core 73.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply apparatus capable of suppressing an operating sound made when moving a movable part into a closing side position. SOLUTION: A driving voltage is built up at time T1, but the driving voltage is controlled so that the driving voltage before closing immediately before a needle 64 moves into the closing side position is a set value. For example, the driving voltage is controlled so that the driving voltage at time T2 is Vp1. If the driving voltage Vp1 before closing is appropriate, the moving speed (an inclination indicated by a symbol K) of the needle 64 can be suppressed, that is, "soft landing" of the needle 64 can be achieved. The driving voltage Vp before closing is set by learning control, that is, the driving voltage before closing is gradually lowered, and whether fuel pressure is lowered is determined to carry out learning.

摘要翻译：解决的问题：提供一种能够抑制将可动部件移动到关闭侧位置时产生的操作声音的燃料供给装置。解决方案：在时间T1建立驱动电压，但是控制驱动电压使得在针64移动到关闭侧位置之前关闭之前的驱动电压是设定值。例如，控制驱动电压，使得时刻T2的驱动电压为Vp1。如果关闭前的驱动电压Vp1适当，则可以抑制针64的移动速度（由符号K表示的倾斜度），即可以实现针64的“软着陆”。关闭前的驱动电压Vp是通过学习控制来设定的，即，关闭前的驱动电压逐渐降低，并且确定燃料压力是否降低，以进行学习。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a clutch enabling to relax collision between a roller and a groove during rotation even when a groove is provided in a collar for improving the meshing performance of the roller. SOLUTION: The groove 25 is provided in an inner peripheral face 8 of the collar 6 for improving the meshing performance of the roller 7, and the groove 25 is internally coated with an elastic resin 26 to form an axial-view perfectly circular contact face contactable with the roller 7. When a drive 4 is driven to be rotated, the roller 7 is rotationally moved around the center axis of the drive 4. At this time, the elastic resin 26 prevents the entry of the roller 7 into the groove 25 to avoid collision between the roller 7 and the groove 25, thus preventing the occurrence of beat and avoiding a deformation or breakage trouble of the roller 7 or the groove 25. On the other hand, when rotating force is applied to a driven 5 side, the roller 7 crushes the elastic resin 26 and the roller 7 and the groove 25 are fitted to each other to improve mutual engaging force, thus keeping the driven 5 in a fixed condition.

摘要翻译：要解决的问题：提供一种离合器，即使在用于提高辊的啮合性能的轴环中设置槽时，也能够在旋转期间缓和辊与槽之间的碰撞。解决方案：槽25设置在轴环6的内周面8中，用于提高辊7的啮合性能，并且槽25在内部涂覆有弹性树脂26，以形成轴向完美圆形接触面可以与辊7接触。当驱动器4被驱动旋转时，辊7围绕驱动器4的中心轴线旋转移动。此时，弹性树脂26防止辊7进入凹槽25，以避免辊7和凹槽25之间的碰撞，从而防止跳动的发生，并避免辊7或凹槽25的变形或断裂故障。另一方面，当旋转力施加到驱动5 侧面，辊7将弹性树脂26和辊7彼此嵌合并且槽25彼此嵌合以提高相互接合力，从而将驱动5保持在固定状态。版权所有（C）2010，JPO＆INPIT
