  • Publication number: 20150222149
    Abstract: A rotation assistance mechanism equipped with an attraction unit having a pair of magnetic bodies for which the opposite poles of the bodies are arranged facing one another. A magnetic body driving unit changes the distance between the pair of magnetic bodies with a prescribed period by means of the rotation of a rear wheel. A shielding unit has a pair of magnetic surfaces, the poles of which are the same as the respective opposing surfaces of the pair of magnetic bodies. A shield-driving unit that, in conjunction with the prescribed period, propels the shielding unit into the interval between the pair of magnetic bodies when the distance between the pair of magnetic bodies is reduced, and retracts the shielding unit from the interval between the pair of magnetic bodies when the distance between the pair of magnetic bodies is increased.

  • Patent number: 9026330
    Abstract: A twin clutch controlling apparatus includes a clutch actuator for controlling a twin clutch TCL, and a manual operation clutch capacity arithmetic operation section for converting an operation amount of a clutch lever L into an electric signal to arithmetically operate a manual operation clutch capacity arithmetic operation value (tqc1tmt) corresponding to the manual operation. The twin clutch controlling apparatus is configured so as to accept a changeover from an Auto mode to a Temp mode in response to an operation of the clutch lever L. When an operation of the clutch lever L is detected during automatic control in the Auto mode, an event that the manual operation clutch capacity arithmetic operation value (tqc1tmt) comes to have a value similar to that of the clutch capacity (tqc1at) calculated in the Auto mode is included in conditions for a changeover to the Temp mode to occur.

  • Patent number: 8977458
    Abstract: A twin clutch controlling apparatus wherein a clutch lever is operated during a deceleration operation in which an auto mode (Auto) is selected, then a shift down action from a gear position “N-2” at which a driving force can be transmitted only by one of an odd number stage side clutch CL1 and an even number stage side clutch CL2 to another position “1-2” at which the transmission gear for transmitting a driving force is switched in response to switching control of the clutch is carried out in response to the operation of the clutch lever. After the shift down action, if re-connection of the clutch is to be carried out by the clutch lever, then the clutch (CL1, CL2) on the side to be driven in response to a manual operation clutch capacity arithmetic operation value (tqc1tmt) is determined in response to a vehicle speed V.

  • Patent number: 8909446
    Abstract: A twin clutch controlling apparatus includes an ATM control unit for controlling a shift actuator and a clutch actuator and a shift pedal P for carrying out shifting request to the ATM control unit. When a shifting request by the shift pedal P is issued, the ATM control unit drives the shift actuator to change over the shift stage to a next stage gear irrespective of an operational amount of a clutch lever L and then causes the manual operation clutch capacity arithmetic operation value (tqcltmt) to correspond to a clutch capacity corresponding to the next stage gear using an operational amount of the clutch lever L that exceeds a predetermined value as a trigger. If a predetermined period of time elapses while the clutch lever L is not operated, then the shifting request is an erroneous operation and the shift stage is returned to an original gear.

The thickness of the lateral end part changes linearly from opposite lateral ends of the lateral center part to the opposite lateral ends of the slit. Coating material is discharged from the slit while applied with pressure, so that the coating material is coated while expanded wider than the width of the slit. The coating material is discharged at 7 liter per minute, and a coating width of a first example is 100 mm, for example. A thickness increase of the overlapped part is +25% even when a width or an overlapped margin z of the overlapped part is 10 mm or 20 mm.
