    Abstract: An artificial muscle includes a housing including an electrode region and an expandable liquid region and a dielectric liquid housed within the housing. The artificial muscle further includes an electrode pair positioned in the electrode region of the housing, the electrode pair comprising a first electrode and a second electrode, wherein the electrode pair is configured to actuate between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric liquid into the expandable liquid region, expanding the expandable liquid region. The artificial muscle also includes a composite electrical insulating layered structure in contact with at least one of the first electrode or the second electrode, wherein the composite electrical insulating layered structure that includes an electrical insulator layer surrounded by adhesive surfaces. The adhesive surfaces are located between one or more flexible electrical insulators.

    Abstract: The invention relates to a cylinder housing (2) for a pressure cylinder (1) of light-weight/hybrid construction, having a support structure (4) comprising an inner tube (6) with ends (7, 8) that are spaced apart in the axial direction, and a first and a second end piece (10, 11) in the region of one of the ends (7, 8) of the inner tube (6). A composite structure (12) made of a fiber-reinforced plastics material is arranged on an outer surface (13) of the inner tube (6). Arranged on an outer surface (16) of the first and the second end piece (10, 11) in each case in a manner distributed over the circumference thereof are a plurality of rod-like winding aids (17) that protrude from the outer surface (16). The winding aids (17) have sufficient strength to allow a winding operation during the application of the threads of the composite structure (12), individual threads of the composite structure (12) being guided during said winding operation around at least one of the winding aids (17) in a deflection region (18) on sides that face away from one another in each case in the axial direction. Following the formation of the composite structure (12), the winding aids (17) are reshaped and at least regionally embedded in the composite structure (12). The invention also relates to a pressure cylinder (1) having such a cylinder housing (2) and to a method for the production thereof.

    Abstract: Soft pneumatic actuators based on composites consisting of elastomers with embedded sheet or fiber structures (e.g., paper or fabric) that are flexible but not extensible are described. On pneumatic inflation, these actuators move anisotropically, based on the motions accessible by their composite structures. They are inexpensive, simple to fabricate, light in weight, and easy to actuate. This class of structure is versatile: the same principles of design lead to actuators that respond to pressurization with a wide range of motions (bending, extension, contraction, twisting, and others). Paper, when used to introduce anisotropy into elastomers, can be readily folded into three-dimensional structures following the principles of origami; these folded structures increase the stiffness and anisotropy of the elastomeric actuators, while keeping them light in weight.

    Abstract: A seal structure includes: first and second members defining a hollow internal area of a fluid device; and a seal member fixed to the first member for sealing a gap between the first and second members. The seal member includes a sliding contact member being in sliding contact with a surface of the second member and formed of a resin. The second member includes a resin layer and a resin layer holding structure. The resin layer is formed by sliding the second member on the sliding contact member to transfer the resin forming the sliding contact member onto a sliding contact portion of the surface of the second member at which the second member comes into contact with the sliding contact member. The resin layer holding structure is a porous film formed by electric discharge surface treatment and holds the resin layer in the sliding contact portion.

    Abstract: A piston cylinder device having a piston stroke measurement includes a cylinder tube (1) having an inner tube (2) made of a nonmagnetic material and an outer tube (3) formed on the outer peripheral surface of the inner tube and made of a fiber-reinforced resin material. A piston (76) fixed to a rod (75) is disposed slidably inside the cylinder tube. A stroke detector is composed of a position indicating magnet (80) disposed in the piston and an elongated sensor (81) disposed in the cylinder tube. The elongated sensor includes a thin elongated pipe (82) extending along the cylinder tube between both of its ends and holds at least one magnetostriction line (87) having a large magnetostriction coefficient, a driving coil (84) wound on at least one of the ends of the thin elongated pipe. A pulsed input current to the drive coil causes magnetostriction phenomenon on the magnetostriction line generating an ultrasonic wave. A detecting coil (86) wound on the thin elongated pipe in a predetermined length separately from the driving coil induces a detection signal generated by reverse magnetostriction when the ultrasonic wave passes by the position of the magnetostriction line corresponding to the position indicating magnet. Also, at least one pin-like magnet (20A, 42A) for correcting a measurement error due to a temperature change of the stroke detector, and disposed at a position adjacent to the detecting coil (86) and more inward in the axial direction than both ends of the detection coil are fixed to both ends of the cylinder tube (1).

    Abstract: A fiber/thermoplastic resin matrix cylinder with a metal lining and a process for manufacturing such a cylinder using metal plasma spray and filament winding techniques are disclosed. In the manufacturing process, a molten metal plasma spray is deposited on a heated and rotating mandrel. After the metal layer has cooled, filament winding techniques are used to deposit a layer of graphite fibers and thermoplastic resin around the metal layer, after which the mandrel is removed. The metal layer remains bonded to the fiber/thermoplastic layer. The process results in a fiber/thermoplastic resin matrix cylinder of low cost, light weight, durability, and survivability.
