  • Publication number: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Patent number: 10240650
    Abstract: A parking brake reduced in size and simplified is installed on a rod-protruding side of a cylinder of a caliper braking device. A second piston is provided within the second cylinder that is coaxially coupled with the cylinder and movable coaxially relative to the rod. A one-way clutch is provided to switch ON/OFF due to a releasing/pressing by the second piston with respect to a switch disposed facing a cylinder side surface of the second piston. A parking operation auxiliary spring is provided on the side of the cylinder within a second cylinder, and a manual release piston is provided in a space of the second cylinder. A parking release lever pushes a manual release rod at the tip end of the manual release piston, pushing the second piston in the direction of retraction of the rod, at the same time as the manual release rod pushes into the rod.

  • Patent number: 9522684
    Abstract: A tip of a pneumatic brake cylinder device is attached rotatably at a base side of a caliper body, and a base end of a first brake lever is attached rotatably to an end part of a cylinder at a side opposite to where the rod protrudes. A center part of the first brake lever is rotatably attached to the body. A front part end of a second brake lever is rotatably attached to a tip of the body, and the base ends thereof come into contact with a tip of the first brake lever. A brake lining and a brake head are attached on an inner surface at a tip of a pressing-force transmission member disposed at a center part front part of the second brake lever. A torque-receiving pin tip is immobilized at the brake head, and a shaft is held on the body via a spherical washer.

  • Patent number: 5390770
    Abstract: A rotation deceleration device used for a sanitary cleaning device which includes a toilet seat and a toilet cover and is attached to a toilet bowl, thereby injecting warm water in the toilet bowl. The rotation deceleration device includes a cylinder having a hydraulic chamber filled with a control oil; a rotation shaft inserted through the cylinder; a control wall radially projected from the rotation shaft to divide the hydraulic chamber into at least two sub chambers; a control valve provided between the control wall and an inner surface of the cylinder. The control valve has a closing wall opposed to a side surface of the control wall so as to be attachable thereto and also has an engaging member opposed to the other side of the control wall so as to be engageable therewith in accordance with the rotation of the rotation shaft. The control valve is formed of a material which has a higher coefficient of thermal expansion than that of a material forming the control wall and the cylinder.

  • Patent number: 4581779
    Abstract: A washing apparatus body mounted on a toilet bowl is provided with a hot-water tank supplied with water by a feed water supply device, such as a pump, a function changeover valve connected to the hot-water tank, a plurality of nozzles connected to the function changeover valve, at least a part of the nozzles being provided within the washing apparatus body, and a vacuum releasing valve positioned in the water path between the hot-water tank and the function changeover valve for discharging water in the water path downstream therefrom after use of the apparatus so that no water remains in the downstream water path in a standby state. Hot-water paths leading from the hot-water tank to the nozzles are made as short as possible so as to permit hot water from the hot-water tank to jet out from the respective nozzles toward a user in a short period of time upon the starting of washing and to minimize heat losses in the lines.
