  • Publication number: 20150152527
    Abstract: Provided are a magnesium alloy sheet having excellent formability in plastic forming, such as press forming, and a magnesium alloy structural member. The magnesium alloy sheet is obtained by subjecting a magnesium alloy to rolling and has a cross section parallel to the thickness direction of the magnesium alloy sheet, in which, when the length of the major axis and the length of the minor axis of each of crystal grains in the cross section are determined, an aspect ratio is defined as the ratio of the length of the major axis to the length of the minor axis (length of major axis/length of minor axis), and crystal grains having an aspect ratio of 3.85 or more are defined as elongated grains, the area fraction of the elongated grains in the cross section is 3% to 20%.

  • Patent number: 8394001
    Abstract: A control device controlling a vehicle's automatic transmission. The automatic transmission engages first and second friction engagement elements by fluid pressure from a pump operating using motive power from the vehicle's motor when a shift position is at a reverse traveling position, places the first friction engagement element on standby at a predetermined pressure that is higher than a stroke starting pressure by which a piston stroke is started and lower than a complete engagement pressure or engages the first friction engagement at the complete engagement pressure when the shift position is at a non-traveling position, and engages a third friction engagement element as a starting shift speed when the shift position is at a forward traveling position.

  • Publication number: 20110032262
    Abstract: A normal bus and an extension bus having the same bit width as the normal bus are provided. A line buffer has a plurality of line regions to store pixel data of input image data. A line buffer writing control portion controls a direction in which the pixel data is to be written to the line buffer. A line buffer reading control portion reads out the pixel data stored in the line buffer and to output the read out pixel data to the buses selectively. A frame memory writing control portion controls a destination in a frame memory to which the pixel data obtained from the buses is to be written. An address control portion controls a writing address in the frame memory. The line buffer writing control portion controls the writing direction in the line buffer in accordance with an image rotation command signal.

  • Patent number: 5829732
    Abstract: An exhaust pipe supporting device includes a generally elliptical body portion integrally formed of an elastic material, such as rubber. The body portion includes a first holder portion having a through-hole to receive a support member associated with a car body, a second holder portion having another through-hole to receive a support member associated with the exhaust pipe. A pair of lateral walls connect the first and second holder portions by attachment at opposite ends to opposed sides of the first and second holding portions. The first and second holding are held in this manner in spaced apart relation to each other, and a central connector is disposed intermediate between the first and second holder portions and connected at opposite sides thereof to the lateral walls. The central connector portion includes a central portion formed as a mass section, which optionally includes a metal mass portion, and opposite lateral portions which extend from the mass section to the opposite sides.
