Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device which can be assembled in a fuel tank without pressing a coupling member for coupling a canister side to a pump module onto the bottom side of the fuel tank by minimizing an opening of a fuel tank for assembling the fuel supply device. SOLUTION: In a fuel supply device, a coupling member 60 is axially movably assembled in a side of a canister 24 and a side of a subtank 32. As a lid module 20 is inserted into a fuel tank 2, the coupling member 60 moves to the inside bottom 4a side of a fuel tank 2 together with a lid module 20 while being guided to a guide part 34 of the subtank 32. A locking part 70 of the coupling member 60 is locked in a side upper end of the subtank 32. When pressing the lid module 20 to an inside bottom 4a side of the fuel tank 2 against biasing force of a spring 80, the coupling part 60 does not move. Instead, the lid module 20 moves toward the inside bottom 4a side of the fuel tank 2 along the coupling member 60. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply system settable in fuel tanks having various depths.
SOLUTION: One end of a metal pipe 18 is pressed into the press-in part 16 of a mounting member 11, and engagingly locked by the mounting member 11. An E-ring 19 is attached to the other end of the metal pipe 18. When the mounting member 11 is separated from a filter case 32, the E-ring 19 is engagingly locked by the locking part 43 of an insertion part 33. Since a coil spring 20 energizes the mounting member 11 and the filter case 32 in the mutually separating directions along the axial direction of the metal pipe 18, the bottom of a sub-tank 22 is regularly pressed onto the inside bottom surface of a fuel tank 1. A projection part 24 protruded from the inside bottom surface is formed on the bottom inside of the sub-tank 22. When the mounting member 11 gets close to the filter case 32, the other end of the metal pipe 18 is engagingly locked by the projection part 34 of the sub-tank 22.

Abstract: PROBLEM TO BE SOLVED: To provide a commutator which can positively electrically connect a contact member an a terminal member and can position both of the members easily and also provide a fuel pump using such a commutator, and a method for manufacturing the commutator. SOLUTION: A commutator 50 is constituted of eight segments which are electrically insulated from each other by means of radial grooves 61, and each segment is constituted of a contact member 51 which brushes by a brush and a terminal member 53. A base metal of a contact members 51 before being divided by the grooves 61 has on the inner side an annular projection projecting toward a rotary shaft of the commutator. In an assembled state of the base metal of the contact members 53 and a base metal of the terminal members before filling in spaces between the contact members 51 and the terminal members 53 with connection material 57, the outer surface of the projection formed in the base metal of the contact members and the inner surface of the base metal of the terminal members surrounding the outer surface of the base metal of the contact members are in contact at several places, thereby allowing the contact members and the terminal members only to rotate. Since the base metal of the contact members and that of the terminal members can be assembled, without adjusting a space between the outer surface of the projection of the base metal of the cost members and the inner surface of the base metal of the terminal members, the number of manufacturing processes can be reduced.

Abstract: PROBLEM TO BE SOLVED: To make a fuel supply device composed of a cover member and a pump module small and flat. SOLUTION: In the fuel supply device, a bellows pipe 50 is connected to a pipe connection part 15 or a pipe connection part 29 arranged roughly perpendicular to a center axis of the cover member 11 at both end parts thereof. Consequently, interference of the pipe connection part 15 with the pipe connection part 29, and interference of a pipe member 15 and a pipe member 29 with other member is reduced even if the fuel supply device 10 is a style supporting a pump module 20 on the cover member 11. Also, interference of the bellows pipe 50 and other member can be reduced. Consequently, the pipe connection part 12, the pipe connection part 29 and the bellows pipe 50 can be stored in a little space formed between the cover member 11 and the pump module 20 without causing interference between members. Consequently, total length in an up-and-down direction, namely in a depth direction of a fuel tank 1 can be reduced and the fuel supply device 10 can be installed in a flat fuel tank 1.

解决方案：在燃料供给装置中，波纹管50连接到管连接部15或者在其两端部大致垂直于盖构件11的中心轴布置的管连接部29。 因此，即使燃料供给装置10是支撑泵模块20的状态，也能够减少管连接部15与管连接部29的干涉，以及管构件15和管构件29与其他构件的干涉 也可以减小波纹管50与其他部件的干涉。 因此，管连接部12，管连接部29和波纹管50能够容纳在盖部件11和泵模块20之间形成的一小部分空间中，而不会造成部件间的干扰。 因此，可以减少上下方向的总长度，即在燃料箱1的深度方向上，并且能够将燃料供给装置10安装在平坦的燃料箱1中。（C） 2006年，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a motor which reduces the number of assembling steps of a rotor, and to provide a fuel pump using the same.
SOLUTION: A cover structure 80 has a disk-like cover 82 and a terminal 88. The cover structure 80 is formed by applying tin-plating to a brass and formed in one member of a metal. A through hole 84 for inserting a shaft 42 is formed at the center of the cover 82. A gap for electrically insulating the cover structure 80 and the shaft 42 is formed between the cover 82 for forming the through hole 84 and the outer peripheral surface of the shaft 42. The terminals 88 are projected in an axial direction from the cover 82 side toward an armature 50 side, and six terminals 88 are formed in the circumferential direction of the cover 82. The six terminals 88 are electrically connected by the cover 82. The cover structure 80 is assembled with the armature 50, and the ends of the coil 62 to the cover structure 80 side are electrically connected by engaging the terminals 88 with the terminal 66 of the armature 50.

Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic oil supplying system supplying a necessary quantity of hydraulic oil while the fuel consumption is enhanced. SOLUTION: A mechanical oil pump 10 is driven mechanically by the driving shaft of an engine, and an electric oil pump 30 includes a pump body 31 and a motor 32 to drive the pump body 31. A pressure accumulating vessel 20 has a pressure accumulating chamber 21 to store the hydraulic oil discharged from the pump 10 when solenoid valves 12 and 35 are closed. When the engine speed is below a specified level, the solenoid valve 12 is opened while the other 35 is closed, and from the two oil pumps, the hydraulic oil is supplied to a secondary oil pressure chamber 52 by driving the pump 30. In the case a continuously variable transmission makes a quick shift, the solenoid valve 12 is closed while the other 35 is opened, and from the pump 30 the hydraulic oil of high pressure accumulated in the chamber 21 is supplied to the secondary oil pressure chamber 52 by driving the pump 30.

Abstract: PROBLEM TO BE SOLVED: To secure electrical insulation between segments each other and to achieve a long life. SOLUTION: A commutator 50 has eight segments formed at equal angle intervals and a fixing part 56 of resin to fix the eight segments. Each segment has a contact member 51 and a terminal member 53 of carbon, and is electrically insulated each other by a radial groove 61. The contact member 51 and the terminal member 53 are electrically connected by a connecting material 57 such as solder at a protuberance part 52. Since a distance between a position where a nail 55 formed on the terminal member 53 and an armature coil are electrically connected by fusing and the connecting material 5 can be parted, the connecting part 57 can be prevented from reaching a fusing temperature even if the terminal member 53 is heated by heat produced when fusing. Accordingly, the segments are prevented from getting conductive by the connecting agent 57 fusing and flowing in the groove 61.
