摘要： PROBLEM TO BE SOLVED: To reduce colliding sounds and prevent damages to gears by relaxing impact caused during transmitting torque from a pinion gear to a ring gear. SOLUTION: A certain time after starting the energization of a starting motor 1, for example, after detecting an engine control signal (a short time before the tooth surface of the pinion gear collides with the tooth surface of the ring gear), the voltage control of the starting motor 1 is started. Specifically, voltage applied to the starting motor 1 is dropped so that a difference in rotating speed between the pinion gear and the ring gear is smaller. Thus, the rotating speed of the starter is lower to make the difference in rotating speed between the pinion gear and the ring gear smaller, and so the tooth surface of the pinion gear has soft abutment on the tooth surface of the ring gear. As a result, the impact is relaxed during the abutment of the gears, reducing the colliding sounds of both gears and preventing damages to the pinion gear and the ring gear.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic switch 1 capable of reducing impact sound between a plunger 4 and a stopper member 5 when the plunger 4 is pushed back by reaction of a spring 12, and allowing the plunger 4 to smoothly move at the time of energizing to an exciting coil 2. SOLUTION: An elastic member 6 is pressed into a cavity part 4a of the plunger 4 and assembled to the plunger 4 with the state that part of the member protrudes to a stopper surface 5a side from an end face 4b opposite to the core side of the plunger 4. The elastic member 6 is formed such that the area of an end face opposite to the core side abutting against a stopper surface 5a when the plunger 4 is pressed back to the direction opposite to the core is smaller than the area of an end face 4b opposite to the core side of the plunger 4. With such a structure, the area where the elastic member 6 abuts against the stopper surface 5a becomes small and when the plunger 4 is sucked, the elastic member is not easily released from the stopper surface 5a and can smoothly move.

摘要： PROBLEM TO BE SOLVED: To reduce an internal short current flowing between segments 2a of a commutator 2. SOLUTION: A brush 3 comprises conducting materials 3a and insulating layers 3b alternately disposed in their width direction corresponding to the circumferential direction of the commutator 2. A width B of the conducting material 3a is narrower than a width A of the insulating part 2b in the commutator 2. The conducting materials 3a are connected to a pigtail 4 attached to an upper end of the brush 3. When the segments 2a adjacent in the circumferential direction of the commutator 2 are shorted through the brush 3, the current does not directly flow from the first conducting material 3a1 to the second conducting material 3a2 since the insulating layer 3b intervenes between the first conducting material 3a1 contacting one segment 2a1 and the second conducting material 3a2 contacting another segment 2a2, and the internal short current is reduced by an increase of resistance since the current flows from the conducting material 3a1 to the second conducting material 3a2 through the pigtail 4.

摘要： PROBLEM TO BE SOLVED: To provide a drain pipe capable of preventing break of legs and pawls caused by misalignment in assembling and surly draining water and the like.
SOLUTION: The drain pipe 4 of the invention is constructed of a pipe member 40 and a connection member 41. The connection member 41 includes a base 41a, the legs 41b, 41c and the pawls 41d, 41e. Outer peripheral surfaces of walls 41f, 41g are formed in a shape corresponding to an inner peripheral surface of a drain hole. The walls 41f, 41g serve a guide and misalignment between the connection member 41 and the drain hole 30a can be prevented. Break of the legs 41b, 41c and the like caused by the misalignment can be therefore prevented. The height of the walls 41f, 41g is set equal to or smaller than a height to tips of the pawls 41d, 41e. After assembling, the tips of the walls 41f, 41g do not project inward of an end frame. Drainage of water and the like accumulated in the end frame is not inhibited.

摘要： PROBLEM TO BE SOLVED: To suppress impact noise and vibration by absorbing an impact energy generated by the collision of a plunger 5 with a core 10. SOLUTION: A yoke 4 is formed in a cylindrical shape having a bottom surface, and a recessed part 4a is formed in the bottom surface front side of the yoke 4 by recessing inward the bottom surface center part thereof. An elastic member 11 (for example, rubber) is fitted to the recessed part 4a, The elastic member 11 is formed almost in same size as that of the recessed part 4a, and forms almost the same surface as the front surface of the yoke 4 without being projected largely from the front surface of the yoke 4 to the outside. Thus, since the impact energy generated when the plunger 5 is sucked and collides with the core 10 can be absorbed by the elastic member 11, impact noise is relieved and changed from normal high metallic noise to low noise, and the noise leaking to the outside through the yoke 4 can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic switch 1 in which a plunger 3 is prevented from sticking to a cushion member 20 to allow the plunger 3 to move certainly when an exciting coil 2 is energized.
SOLUTION: The electromagnetic switch 1 has a stopper member 5 for regulating a position where the plunger 3 returns to. The cushion member 20 made of rubber is arranged in a recessed space formed at the stopper member 5 and a plate 21 of a non-magnetic material is attached to the cushion member 20. When a magnetic force disappears by stopping energizing the exciting coil 2, the plunger 3 is pushed back by the reaction of a return spring 4 in the direction opposite to an iron core so that the plunger 3 collides with the plate 21 of the non-magnetic material to stop. Thus, the plunger 3 does not stick to the cushion member 20 by the variation of a temperature environment, etc., and the plunger 3 is not attracted to the plate 21 of the non-magnetic material when the exciting coil 2 is energized, so that the plunger 3 is certainly released from the plate 21 of the non-magnetic material.

摘要翻译：要解决的问题：提供一种电磁开关1，其中防止柱塞3粘附到缓冲构件20上，以允许柱塞3在励磁线圈2通电时肯定地移动。解决方案：电磁开关1具有用于调节柱塞3返回的位置的止动构件5。由橡胶制成的缓冲构件20布置在形成在止动构件5上的凹陷空间中，并且非磁性材料的板21附接到缓冲构件20.当通过停止激励励磁线圈2来激励磁力而消失时，柱塞3通过复位弹簧4在与铁芯相反的方向的反作用力被推回，使得柱塞3与非磁性材料的板21碰撞停止。因此，当激励线圈2通电时，柱塞3不会因温度环境等的变化而粘附到缓冲构件20上，并且柱塞3未被吸附到非磁性材料的板21，因此柱塞3肯定从非磁性材料的板21释放。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a magnet switch capable of suppressing bouncing of a movable contact against a fixed contact. SOLUTION: This magnet switch 1 comprises a casing 2, a fixed contact member 5 (6) fixed within the casing 2 and having a fixed contact 50 (60), an electromagnetic coil 34, a plunger 31 reciprocating by magnetic force of the electromagnetic coil 34, and a movable contact member 4 having a movable contact 44 (55) attachable/detachable to/from the fixed contact 50 (60) by reciprocating integrally with the plunger 31 and a biasing part for biasing the movable contact 44 (45) in the direction of the fixed contact 50 (60). The movable contact member 4 is arranged in series with the biasing part and has a recoiling suppressing part having smaller spring force than that of the biasing part, to suppress the bouncing of the movable contact 44 (45) when the movable contact 44 (45) is abutted on the fixed contact 50 (60).
