  • Publication number: 20240181225
    Abstract: A balloon for a catheter includes an inflatable portion, a distal end connecting portion, and a proximal end connecting portion. The balloon for the catheter also includes an inner side thick film portion and a thin film portion having differing thicknesses from each other. The thickness of the inner side thick film portion is greater than the thickness of the thin film portion. An inner surface at the inner side thick film portion protrudes further toward an inner side than an inner surface at the thin film portion. An outer surface at the inner side thick film portion does not protrude further to an outer side in the radial direction than an outer surface at the thin film portion.

  • Publication number: 20240167488
    Abstract: A fluid circuit includes: a fluid supply device that delivers a working fluid; and an accumulator that accumulates the working fluid which is increased in pressure. A variable throttle valve and the accumulator are disposed in a branch flow passage branched from a main flow passage extending from the fluid supply device to an actuator. A first pressure detector is provided between the variable throttle valve and the accumulator, a second pressure detector is provided in the branch flow passage between the main flow passage and the variable throttle valve, and the variable throttle valve is controllable based on pressures detected by the first pressure detector and the second pressure detector. A check valve is provided in the branch flow passage.

  • Publication number: 20240159255
    Abstract: A first switching valve that switches between flow passages which allow communication between a first pressure-receiving chamber and a fluid supply device side and flow passages which allow communication between a second pressure-receiving chamber and the fluid supply device side, according to a change in a fluid pressure to be applied, and a second switching valve that is switched to flow passages which apply the fluid pressure to the first switching valve, are provided. The second switching valve includes return device, and is provided to be reciprocatable between an operation position to which the second switching valve is moved by a stroke of a piston and a return position to which the second switching valve is moved by the return device. The piston and the second switching valve are movable independently of each other.

  • Publication number: 20240159252
    Abstract: A fluid circuit includes first switching valve that switches between flow passages and first flow passages according to a change in a fluid pressure to be applied, a second switching valve that is switched to a flow passage which applies the fluid pressure to the first switching valve, when a piston has reached an initial position or an end position, and second flow passages. A biasing force of a biasing member when the piston reaches the end position is smaller than a pressing force acting on the piston due to the fluid pressure caused by a fluid supply device, and a biasing force of the biasing member when the piston reaches the initial position is larger than a sum of a flow passage resistance force acting on the first flow passages and a flow passage resistance force acting on the second flow passages.

  • Publication number: 20240127609
    Abstract: To effectively determining whether the driver is in the specific state according to the use of the driving assistance device, provided is a driver monitoring device which is applied to a vehicle having a driving assistance device configured to execute a predetermined driving assistance control for assisting the driving of a driver. The driver monitoring device comprising a driver state acquisition unit configured to acquire a state of the driver; and a driver state determination unit configured to determine that the driver is in a specific state when the state of the driver acquired by the driver state acquisition unit satisfies a predetermined condition. The driver state determination unit is configured to relaxes the predetermined condition when the driving assistance device is executing the driving assistance control, as compared with a case where the driving assistance device is not executing the driving assistance control.

  • Publication number: 20240123198
    Abstract: A balloon has an inflatable portion that forms a tube shape extending in an extending direction in an inflated state, a distal end connecting portion provided to an end portion of the inflatable portion on one side thereof, and a proximal end connecting portion provided to an end portion of the inflatable portion on the other side thereof. At least the inflatable portion includes a plurality of first portions that forms wings in the deflated state and a plurality of second portions that is adjacent to the plurality of first portions in a circumferential direction centered on the center axis. In the process of changing shape from the inflated state to the deflated state, the plurality of second portions moves towards the center axis in advance of the plurality of first portions and thereby forms, in the inflatable portion, indentations recessed toward the center axis.
