  • Patent number: 9541884
    Abstract: An intermittent driving device includes a shaft, an input gear, an output gear, a connecting member that rotates in a state of being connected to the input gear, a state of the connecting member being switched between a state of being connected to the output gear and a state of being disconnected from the output gear, a moving member, a cam member that has a cam surface having a shape that causes the moving member to move in the axial direction and guides the connecting member into the state of being connected to the output gear or the state of being disconnected from the output gear, a rotation-applying member that applies a rotational driving force to the cam member, and a switching member that switches between a state where a rotational operation of the cam member is hindered and a state where the rotational operation is allowed.

  • Patent number: 9529315
    Abstract: A driving-force transmitting device includes a driving-side joint portion that couples to a receiving-side joint portion provided at an end of a rotatable body and transmits a rotational driving force of a driving source. The driving-side joint portion and the receiving-side joint portion are a pair of involute spline joints including an external gear and an internal gear, a number of teeth of one of the gears being smaller than a number of teeth of the other gear.

  • Patent number: 9430886
    Abstract: A driving diagnosis device includes storage device which stores plural pieces of advice and a processor. The processor makes a diagnosis on driving by a driver according to vehicle information indicating at least one of behavior of a certain vehicle and an operation of the driver while the driver is driving the certain vehicle. The processor judges a degree of influence, on the diagnosis, of a driving experience of the driver before the driver drives the certain vehicle according to history information as for a history of the driver driving one or more different vehicles including the certain vehicle. And the processor determines to present to the driver a piece of advice stored in the storage device, from among plural pieces of advice, in association with a combination of a result of the diagnosis and the judged degree of influence.

  • Patent number: 9263267
    Abstract: In a manufacturing method of a silicon carbide semiconductor device, a semiconductor substrate made of single crystal silicon carbide is prepared. At a portion of the semiconductor substrate where a first electrode is to be formed, a metal thin film made of electrode material including an impurity is formed. After the metal thin film is formed, the first electrode including a metal reaction layer in which the impurity is introduced is formed by irradiating the metal thin film with a laser light.

  • Patent number: 9256995
    Abstract: An apparatus for diagnosing driving behavior includes a storage unit that stores ideal running information defining a relationship between a vehicle speed and a vehicle position corresponding to a road situation, a generation unit that generates actual running information expressing a relationship between an actual vehicle speed and an actual position when a vehicle passes through a road, a condition identification unit that identifies a matching condition where the degree of correlation of the actual running information with the ideal running information exceeds a predetermined value, and a diagnosis unit that diagnoses a driving behavior of a driver of the vehicle, based on a degree of similarity between the ideal running information and the actual running information under the matching condition identified in the condition identification unit.

  • Publication number: 20150309584
    Abstract: A processor recognizes a shape of an indicator that performs an operation in a space on an object to be operated that is displayed on a display surface. The processor specifies an operation assigned to the recognized shape of the indicator. The processor changes a size of the space in which the operation is performed in accordance with the specified operation.

  • Patent number: 9105558
    Abstract: A silicon carbide semiconductor device includes: a semiconductor substrate made of silicon carbide single crystal and having a principal surface and a backside; and an ohmic electrode contacting one of the principal surface and the backside of the semiconductor substrate in an ohmic manner. A boundary between the ohmic electrode and the one of the principal surface and the backside of the semiconductor substrate is terminated with an element, which has a Pauling electronegativity larger than silicon and a binding energy with silicon larger than a binding energy of Si—H.

  • Patent number: 9026006
    Abstract: An image forming apparatus includes a housing; a driving portion provided in the housing and configured to generate a driving force; an interchangeable member interchangeably provided in the housing and having a driving-force-receiving portion at which the driving force is received, the interchangeable member being configured to rotate by receiving the driving force at the driving-force-receiving portion; a driving-force-transmitting portion provided in the housing and connecting the driving portion and the interchangeable member to each other, the driving-force-transmitting portion being configured to transmit the driving force from the driving portion to the interchangeable member; and a connecting-and-disconnecting mechanism that allows the driving force to be transmitted between the driving portion and the driving-force-transmitting portion when the interchangeable member rotates, and prevents the driving force from being transmitted between the driving portion and the driving-force-transmitting portion w
