| 20100000365 | LEGGED ROBOT - A legged robot that ensures a large step length while keeping the height of the trunk low is realized. The legged robot is provided with a trunk, a pair of legs, and a pair of sliding joints. Each of the sliding joints links one end of each of the legs to the trunk so as to slide in a front and rear direction with respect to the trunk. For each step, one leg is caused to slide forward, and the other leg is caused to slide backward. It is possible to ensure a predetermined distance between the end portion of the one leg and the end portion of the other leg. The legged robot can make the step length large by an amount that is equivalent to this distance irrespective of the length of the legs. | 01-07-2010 |

| 20090260472 | LEGGED ROBOT - A legged robot is provided whose trunk link is not prone to wobble in the front-back direction during walking. The legged robot is equipped with a trunk link and a pair of legs. Each leg has a pitch joint capable of rotating the connected links in a plane that intersects with a line extending in a lateral direction of the robot. Rotation centers of the pitch joints are located above a center of gravity of the trunk link. The legged robot walks mainly by swinging the legs backward and forward around such rotation centers. Hence, the trunk link wobbles mainly in the front-back direction around the rotation centers as the robot walks. Because the center of gravity of the trunk link is located below the rotation centers, the gravitational force acting on the trunk link acts in a direction to suppress swinging of the trunk link during walking. Due to this, the trunk link of the legged robot is not prone to wobble in the front-back direction during walking. | 10-22-2009 |

| 20120028192 | CONTROL METHOD AND CONTROL SYSTEM FOR EXPOSURE APPARATUS - According to one embodiment, a control method for an exposure apparatus is disclosed. The method can include retrieving, from a database, a correction amount of alignment correction at a time of exposure of a wafer and an inclination amount of a wafer stage with respect to an optical axis of an exposure optical system at the time of exposure. The method can include making a determination on the inclination amount based on a predetermined condition. The method can include making a determination on the correction amount based on the predetermined condition. In addition, the method can include issuing an alarm when the inclination amount and the correction amount both satisfy the condition. | 02-02-2012 |

| 20120121366 | SUSPENDING MEMBER BREAKAGE PREVENTING MECHANISM IN A SPARE WHEEL HOLDING APPARATUS - A spare wheel holding apparatus includes a device for winding up a spare wheel with a suspending member. The device includes a rotation restricting plate and a rotation restricting pin having a projecting pin portion. When a winding-off force is applied to the suspending member, the rotation restricting plate abuts on the projecting pin portion, thereby stopping winding-off of the suspending member. A suspending member breakage preventing mechanism also uses the rotation restricting pin as a safety pin. If the winding-off force is larger than that in normal, the projecting pin portion is broken at a root portion, the suspending member is wound off, thereby preventing breakage. The root portion has a smaller thickness than a tip end portion of the projecting pin portion. | 05-17-2012 |
