  • Patent number: 7784593
    Abstract: A brake pad for a bicycle comprises a backing plate formed from titanium, and a friction member bonded to the backing plate through a diffusion layer. The diffusion layer is formed at least in part by thermal spraying copper onto the backing plate. A method of constructing the brake pad comprises the steps of thermal spraying copper on a backing plate formed from titanium to form a copper layer on the backing plate, and bonding a friction member to the copper layer by forming a diffusion layer with the copper layer.

  • Patent number: 7278519
    Abstract: A bicycle disk brake pad comprises a backing plate and a friction member. The friction member comprises a friction brake part and a wear indicating part, wherein the friction part is adapted to contact a rotating brake member, and the wear indicating part is mounted to the backing plate. The friction brake part and the wear indicating part each comprise a common material and a harder material that is harder than the common material. A proportion of the harder material in the wear indicating part is greater than a proportion of the harder material in the friction brake part.

  • Patent number: 4883185
    Abstract: A suspension type transporter suspends a bolt drawing machine through a trolley and a hoist above a pressure container having many bolt attached thereto and transports the bolt drawing machine to a target position. A track settling portion having a guide is provided on an outer periphery of a lid of the pressure container. The suspension type transporter for the bolt drawing machine comprises a guide mechanism which restricts movement of the bolt drawing machine in the air by the guide. The guide mechanism of the transporter is provided with a position detector which can detect a position of the bolt drawing machine. A positioning controller of the suspension type transporter controls the transporter so that the transporter starts at slow speed, is then accelerated to a prescribed speed and is gradually decelerated near the target position.
