  • Patent number: 8167381
    Abstract: A brake fluid pressure control device for a bar handle vehicle has a front wheel brake system which imparts a braking force to a front wheel and a rear wheel brake system which imparts a braking force to a rear wheel. At least one of the brake systems has a master cylinder which generates brake fluid pressure in accordance with an operation amount of a brake operation element, first and second wheel cylinders both of which impart the brake force on one of the front and rear wheels, a first hydraulic path which communicates the master cylinder with the first wheel cylinder, a second hydraulic path which is branched from the first hydraulic path and connected to the second wheel cylinder and a boosting unit which boosts the brake fluid pressure in the second wheel cylinder without boosting the brake fluid pressure in the first wheel cylinder.

  • Publication number: 20060147831
    Abstract: A two-components developer for electrophotography comprises a toner containing at least cyclo-olefin copolymer resin as a binder resin and magnetic material dispersed resin carrier. It is desirable that the Vickers hardness of the toner be in a range from 19.0HV0.01 to 23.0HV0.01, and that the binder resin contain the cyclo-olefin copolymer resin in a range from 50 to 100 wt %. Furthermore, a developing method for electrophotography in which the two-components developer for electrophotography mentioned above is used, is also disclosed.
