  • Publication number: 20050065696
    Abstract: A brake device includes an actuator which is provided on a wheel side of a vehicle having a suspension, the actuator generates a braking force by being electrically driven. A drive controller is also provided for receiving a signal regarding the braking force from a vehicle motion controller and sensors, and driving the actuator accordingly. To reduce the number of high cost bending wires necessary to communicate between the sensors, the drive controller and the vehicle motion controller, the drive controller and the sensors are attached to the actuator side (unspring-mass).

  • Publication number: 20020035947
    Abstract: A car body 8 is supported on a bogie frame 4 through an air spring 5. Along to a width direction of the car body 8, to the bogie frame 4 a torsion bar 11 is provided. At both ends of the torsion bar 11, links 15 and 15 for inclining to direct for an inner side of the car body 8 through levers 13 and 13 are provided. Accordingly, a rolling displacement of the both ends of the car body is restricted and an upper and lower displacement in the same phase is not restricted. According to an occurrence of an excess centrifugal acceleration which acts on the car body 8, a car body inclination according to a link mechanism can be operated. For this reason, a light weight structure and a low cost structure can be attained. An inclination device having a light weight structure, a left and right riding good feeling in the passenger in a car, and a high fail-safe characteristic can be obtained.

  • Patent number: 4777499
    Abstract: A method and an apparatus for recording an image is disclosed, in which toner is supplied between a conductive recording drum covered with an insulating material and recording electrodes with the forward end thereof with a small gap from the drum and inclined at a great angle upstream of the direction of rotation of the recording drum. A toner carriage force is generated in the toner to flow out downstream by rotation of the recording drum. A permanent magnet is arranged in the recording drum to form a toner chain inclined at a great angle downstream of the recording drum from the forward end of the recording electrodes. The component of the magnetic force of the magnet in the direction of drum movement is balanced with the toner carriage force.
