  • Patent number: 11110885
    Abstract: A gas generator includes an igniter, a cup-shaped member, and a fixing member. The cup-shaped member accommodating an enhancer agent bursts or melts at the time of activation. The fixing member fixing a filter does not burst and melt even at the time of activation. Ra and Ha satisfy a condition of Ra/Ha 1.00 where Ra represents an inner diameter of a sidewall portion of the cup-shaped member and Ha represents a distance between a top wall portion of the cup-shaped member and the igniter. The sidewall portion includes a first region surrounded by a partition wall portion of the fixing member and a second region not surrounded by the partition wall portion. The partition wall portion has an end portion arranged closer to a top plate portion than the igniter. A gas generating agent is arranged to face the top wall portion, the second region, and the partition wall portion.

  • Publication number: 20210221324
    Abstract: A gas generator includes a housing constructed by combining and joining a plurality of shell members. One of the plurality of shell members includes a cylindrical portion and a flange portion. The cylindrical portion is provided with a plurality of gas discharge openings including gas discharge openings different in opening area from one another. The flange portion is shaped such that a distance from an axial line of the cylindrical portion to an outer edge of the flange portion is non-uniform. When a perpendicular line is drawn to the axial line from a maximum outer geometry position in the outer edge of the flange portion most distant from the axial line, a gas discharge opening arranged closest to the perpendicular line is a gas discharge opening other than a gas discharge opening largest in opening area among the plurality of gas discharge openings.

  • Patent number: 9375068
    Abstract: In a click-type applicator, when the propelling element is moved forwards by a clicking operation, the advancing motion is transformed into a rotary motion of a transfer cam element in one direction by the function of guide slots of the propelling element and projected parts so that when a cam portion of transfer cam element meshes with a cam portion at the rear of a rotary cam element, the rotation of the transfer cam element causes rotary cam element to rotate and thereby move the screw shaft and hence a piston forwards. On the other hand, by releasing the clicking operation, propelling element is moved backwards due to the repulsive force of a spring, and the backward motion is transformed into a rotary motion of transfer cam element in the other direction by the function of the guide slots and projected parts so as to restore the original position.

  • Patent number: 8597086
    Abstract: A tool holder is provided with a main body, a taper cone, a working portion, a coolant flow passage, and an adjuster. The taper cone includes a taper portion and movable in an axial direction of the main body. The working portion is mounted on an outer peripheral portion of the main body and includes a taper bottom surface which engages with the taper portion. The taper bottom surface is movable in a radial direction of the main body based on a movement of the taper cone in the axial direction. A coolant flows through the coolant flow passage such that a part of the coolant presses and moves the taper cone in the axial direction and another part of the coolant flows out to an outside so as to adjust a pressing force. The adjuster is fitted into a hole penetrating the main body and includes a coolant flow-out hole for adjusting a flow-out of the coolant.
