  • Publication number: 20100170764
    Abstract: An automatic transmission includes a clutch, a clutch drum, a piston, and a brake. The clutch drum, the clutch, and the brake are arranged in sequence in an interior space formed by joining a transmission case to a rear case in an axial direction from the rear case side. A separating/guiding wall that is provided in a circumferential direction so as to define a surplus lubricating oil trapping space for trapping surplus lubricating oil that gathers on an inner peripheral surface of the transmission case and in a second brake, and causes trapped surplus lubricating oil guided thereby into the surplus lubricating oil trapping space to flow downward in the circumferential direction, and a holding mechanism for restricting axial movement of the separating/guiding wall, are provided in relation to spline fitting portions formed on the inner peripheral surface of the transmission case.

  • Publication number: 20100025937
    Abstract: A sealing device that hermetically seals a gap between a first member and a second member that is reciprocally movable with respect to the first member. The sealing device seals liquid supplied into a pressurizing chamber surrounded by the first member and the second member. The sealing device includes a seal member that is attached to the second member. The seal member slides relative to the first member while being in contact with the first member. The seal member includes a base portion and a protruding portion. The protruding portion protrudes from the base portion toward the first member to separate the first member from the base portion. After the liquid is supplied into the pressurizing chamber to fill the pressurizing chamber with the liquid, the protruding portion elastically deforms to bring the base portion into close contact with the first member.

  • Patent number: 7581180
    Abstract: A portable terminal in which the labor in inputting plural characters and a variety of information can be relieved in case limitations are imposed on the number of available keys. The portable terminal includes an LCD 26, a memory 17 for storing the dictionary information comprised of plural words and exemplary sentences, a key input unit 29 for inputting unit characters, a CPU 13 for retrieving from the memory the words and/or exemplary sentences displayed on the LCD 26 based on the input from the key input unit 29 and/or on the character string already finalized, and a jog dial 40. A desired word and/or exemplary sentence is selected from the plural words and/or exemplary sentences retrieved by the CPU 13 responsive to rotation of the jog dial 40 and displayed on the LCD 26 and the information on the finalized character string is generated.

  • Publication number: 20080229878
    Abstract: A differential gear unit divides an input driving force into first and second outputs, and permits a difference between the first and second outputs. The differential gear unit includes a differential case serving as a casing that defines an internal space and an opening communicated with the internal space and that is rotatable in a given direction and an opposite direction. The differential case includes a flange portion as an input portion to which the driving force is input. The differential case is configured such that the fatigue life of the differential case when the driving force is repeatedly input in the flange portion in the direction R1 is longer than the fatigue life of the differential case when the driving force is repeatedly input in the flange portion in the opposite direction; R1 is the rotational direction in which the vehicle runs forward.

  • Publication number: 20080060897
    Abstract: A support structure for supporting a brake, as a frictional coupling device, includes a snap ring, a friction plate, and a back plate. The snap ring fits in a groove that extends in a circle. The back plate is disposed between the friction plate and the snap ring. The back plate is pressed against the snap ring. The snap ring has a first end face that faces the back plate and a second end face that faces the opposite side from the first end face and is in contact with a sidewall of the groove. The back plate has an end face that is in contact with the first end face. The static friction coefficient between the first end face of the snap ring and the end face of the back plate is smaller than that between the second end face of the snap ring and the sidewall of the groove.

  • Patent number: 7320658
    Abstract: In a lubrication groove, which is formed in an insertion hole into which is inserted an output shaft, and which winds around the circumference of the insertion hole while advancing in the axial direction of the insertion hole, there is a portion that is farther to the outside than a perpendicular plane that is perpendicular to a center plane of a differential case on which lie the axial centers of the insertion hole and a pinion gear shaft, the perpendicular plane including a line of intersection of the center plane and the insertion hole. That portion is a perpendicular groove portion which is parallel to a plane that is perpendicular to the axial center of the insertion hole. Accordingly, when extracting a core for forming the insertion hole and the lubrication groove from a die, projections formed on the core for forming the lubrication groove will not interfere with the die. As a result, it is possible to form the lubrication groove during casting of the differential case using that core.

  • Patent number: 7180527
    Abstract: This invention is relative with a text displaying terminal unit used for preparation, transmission/reception and display of a text message. A text message entered by a user is collated to a keyword and, if there is a keyword in the text, displaying attributes of the text and/or the background image are added to the text to send the resulting text added by the displaying attributes to a server (400). Alternatively, the server may collate the text to the keyword to add the displaying attributes of the text and/or the background image to the text. A receiving side terminal unit receives an XML document (240b), added by the displaying attributes, from the server to display the XML document added by the displaying attributes as a motion text message. This motion text message may also be provided by the server to the user as the Web information.

  • Patent number: 7142890
    Abstract: A method of three-dimensionally rotating a plurality of menus displayed in an ordered stack on a display unit of a portable telephone. The method displays the plurality of menus three-dimensionally on the display unit according to the ordered stack. The menu displayed in front is a current menu and the remainder of the menus are displayed in order behind the current menu. A menu rotation direction is selected and the plurality of menus are rotated in the menu rotation direction in accordance with the ordered stack. In this manner, the next menu in the ordered stack is rotated in the menu rotation direction to the front and becomes the current menu.

  • Publication number: 20050155826
    Abstract: A diaphragm spring is formed so as to be elastically deformable between a first shape for maintaining an engaged state for engaging a brake disc with a pressed plate without requiring the continuous operation of a hydraulic cylinder, and a second shape for maintaining a disengaged state for disengaging the brake disc from the pressed plate without requiring the operation of the hydraulic cylinder. Therefore, after the shape of the diaphragm spring is made one of the first shape and the second shape due to temporary operation of the hydraulic cylinder, power for continuously operating the hydraulic cylinder for maintaining the engaged state or the disengaged state is not required. As a result, an energy loss is not caused, and the fuel efficiency is increased.
