摘要： Disclosed herein are a high-voltage generator for an x-ray source, an x-ray gun, an electron beam apparatus, a rotary vacuum seal, a target assembly for an x-ray source, a rotary x-ray emission target, and an x-ray source. These various aspects may separately and/or together enable the construction of an x-ray source which can operate at energies of up to 500 kV and beyond, which is suitable for use in commercial and research x-ray applications such as computerised tomography. In particular, the high-voltage generator includes a shield electrode electrically connected intermediate of a first voltage multiplier and a second voltage multiplier. The electron beam apparatus includes control photodetectors and photo emitters having a transparent conductive shield arranged therebetween. The rotary vacuum seal includes a pumpable chamber at a position intermediate between high-pressure and low-pressure ends of a bore for a rotating shaft. The rotary target assembly is configured such that when a torque between a bearing housing and a vacuum housing exceeds a predetermined torque, the bearing housing rotates relative to the vacuum housing. The rotary x-ray emission target has a plurality of target plates supported on a hub, the plates being arranged on the hub to provide an annular target region about an axis rotation of the hub. The x-ray gun is provided with a shield electrode maintained at a potential difference relative to the x-ray target different to the electron beam emission cathode.

摘要： An actuator includes a ram structure slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. A fluid passageway structure in the ram structure defines a path for fluid to flow through the ram structure and includes an outlet in a sidewall of the ram structure. A cushioning seal located between the ram structure and the cylinder structure can engage the ram structure and a cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward an open end of the cylinder structure. The cushioning seal can move during ram structure retraction in a direction of ram structure retraction such that fluid flowing out of the ram structure sidewall outlet, when the outlet is in the gap first portion, flows between the seal and the cylinder cap.

摘要： A shock absorber includes: a damping valve that suppresses a flow of operating fluid due to the sliding of a piston to generate damping force; a bottomed tubular pilot case that forms a pilot chamber that causes pressure to act on the damping valve in a valve closing direction, together with the damping valve; and an annular seal member (146) that is provided to be fixed to the outer circumferential side of a rear surface of the damping valve, and is fitted into a tube of the pilot case so as to be slidable and to be in a liquid tight manner. A part of the flow of the operating fluid is guided to the pilot chamber and opening of the damping valve is suppressed by the pressure of the pilot chamber. An annular concave portion (380) is formed on the outer circumferential side of the seal member (146), and an annular convex portion (385) is formed on the inner circumferential side of the seal member (146).

摘要： The invention provides a sealing device which can inhibit an external dust in an atmospheric side from intruding into a lip end, thereby inhibiting a sealing fluid leakage by trapped dust. In a sealing device inhibiting leakage of a sealing fluid in an inboard side to an atmospheric side, coming into contact with a shaft by a seal lip end and circumferentially having in an atmospheric side inclined surface of the seal lip with a plurality of screws exerting a pumping action to the sealing fluid, a three-dimensional shape for preventing the dust intrusion is provided between the screws so as to inhibit the external dust intrusion in the atmospheric side toward the lip end. The three-dimensional shape is constructed by a projection or a groove extending in a parallel direction to the lip end. The projection or the groove is connected to the screws longitudinally in both end portions.
