  • Patent number: 9128488
    Abstract: In a movement direction control apparatus and a non-transitory computer readable medium, a reaction torque accompanying rotation of a rotor is utilized to control a rotation angle of a body in a yaw direction. A specification of a yaw angle of a wheel as a target of the movement direction is received, and information of a friction torque is acquired. A rotation angular acceleration in the yaw direction is calculated, based on the yaw angle, the specification of which has been received, and the reaction torque is calculated, based on the calculated rotation angular acceleration in the yaw direction. An operation instruction to a motor for yaw is generated, based on the calculated reaction torque and the acquired information of the friction torque.

  • Patent number: 8895947
    Abstract: An ultraviolet light generating target 20 includes a substrate 21 made of sapphire, quartz or rock crystal; and a Pr:LuAG polycrystalline film 22, provided on the substrate 21, that generates ultraviolet light upon receiving an electron beam. By using a Pr:LuAG polycrystal as the target, the ultraviolet light generating efficiency can be increased more remarkably than when a Pr:LuAG single crystal film is used.

  • Patent number: 8548679
    Abstract: An overturn prevention control device for a two-wheel vehicle having a vehicle body, a front wheel, an actuator that steers the front wheel, a rear wheel, and a rear-wheel driving portion, includes an angular velocity sensor and a control unit arranged to output a steering angle command signal for controlling the actuator. The angular velocity sensor includes a detection axis, is mounted on the vehicle body such that the detection axis is downwardly inclined at a predetermined angle relative to a forward direction of the vehicle body, and detects an angular velocity about the detection axis. The angular velocity detected by the angular velocity sensor includes an angular velocity in a lateral direction of inclination and an angular velocity in an azimuthal direction. The zero-set error and offset noise are incorporated into the azimuth angle command. Thus, the two-wheel vehicle can be prevented from overturning.

  • Patent number: 8277012
    Abstract: A conveyance unit continually conveys sheets of the number of continual prints. A head control section controls ejection of ink droplets from inkjet heads in such a way that there are produced image dots which make up an image to be printed on each of the sheet every time the sheet is conveyed and flushing dots corresponding to flushing dot candidates, among flushing dot candidates for flushing patterns included in a flushing pattern group determined from the continual print count, which are placed at locations where the image dots are not to be produced.

  • Patent number: 8147145
    Abstract: An increase in the temperature of a sliding bearing can be suppressed, and it is possible to reduce the temperature of the bearing and prevent burning and damage. The bearing is divided in two and composed of a liner and a base metal. The liner is disposed on an inner circumferential side of the bearing, and the base metal is disposed on an outer circumferential side of the bearing. A lower liner of the bearing liner, which is located on a load-receiving side, has a cooling groove formed in an outer circumferential surface thereof and extending along a circumferential direction thereof. A lubricant is cooled in the cooling groove and supplied to reduce the temperature of a shaft-sliding surface of the bearing. The lubricant is supplied to the bearing, increases in temperature due to the cooling and has low viscosity.
