An insulated core stud for use in the core structure of at least one of a stator and a rotor of a dynamoelectric machine is adapted to pass through holes contained in laminations of the core structure. The insulated core stud has a central portion and a first layer of heat shrinkable tubular insulation shrunk fit onto and covering at least the central portion of the core stud that passes through the laminations. One or more additional layers of heat shrinkable tubular insulation are shrunk fit onto at least a portion of the first layer of insulation that passes through the laminations. These second layers provide mechanically protection to the underlying layers of insulation against breaks occurring in the electrical insulation when the laminations and core studs are assembled into the core structure.

A bicycle fork includes a fork shaft configured to be rotatably borne by headset bearings in a head tube of a bicycle frame so as to rotate about a steering axis. The fork shaft includes a cylindrical fork shaft segment that is disposed eccentrically with respect to the steering axis. The cylindrical fork shaft segment is a right circular cylinder having a hollow interior, a cylindrical inner surface and a central longitudinal axis that lies within a symmetry plane of the bicycle frame and extends parallel to the steering axis. The central longitudinal axis of the cylindrical fork shaft segment is spaced apart from the steering axis in a direction of eccentricity that points in an opposite direction with respect to a forward direction of travel of the bicycle.

The invention discloses a durable communication cable, which belongs to the technical field of cables, and can realize coating type mechanical protection on a cable body by covering a specific area on the cable body with mutually lapped protective flakes, and cannot influence bending and stretching of the cable body in a normal range on the other hand, meanwhile, a certain gap is kept between the protective flakes and the cable body to meet heat dissipation, the inner supporting magnetic bundles at the inner ends of the protective flakes can provide an elastic buffering effect, damage caused by the fact that external force directly acts on the cable body is avoided, and even if the cable body cracks due to excessive bending or stretching, a magnetic attraction rubber bag on the inner side of the cable body attracts the corresponding inner support magnetic bundle to promote the inner support magnetic bundle to extend to the cracking part, and meanwhile, the magnetic attraction rubber bag can also be compressed to release glue to glue the cracking part, so that a temporary repairing effect is achieved, early warning is given to technicians, and the durability of the cable body can be greatly improved.

A winding arrangement comprising at least one multi-layered winding body having a plurality of windings associated with a winding band and an optical waveguide, which is introduced therein or therethrough. The optical waveguide is wound into the winding body in the area where it is introduced therein and comprises, at least in the area, a light-guiding fiber and a protective layer applied thereto. The protective layer consists either entirely or partially of a layer of material having a maximum elasticity module of 2.5 GPa.

The invention discloses a stimulated self-bulging optical cable, and belongs to the technical field of optical cables. The stimulated self-bulging optical cable can perform buffer protection on an external force with relatively low strength to avoid damage to a cable core by imitating a stimulated reaction of a human body when subjected to the external force, and stimulated capsules can imitate subcutaneous tissues of the human body to be damaged when subjected to the external force with relatively high strength to avoid damage to the cable core. Therefore, part of the material of the feedback ball is released through the simulated cell capsule, the material starts to trigger a chemical reaction and releases a large amount of gas after being in contact with water which is filled in the simulated cell capsule in advance, the gas enters the expansion assisting ball through the stimulated capsule and then expands, and then a bulging phenomenon after the stimulated reaction is formed on the outer cover; technicians can be reminded of the stress area to facilitate targeted maintenance, meanwhile, the protection capacity of the bulge area is more prominent under the buffering effect of gas when the bulge area faces subsequent external force, and in addition, color development of the bulge area is more identifiable.

A strip line filter includes a substantially rectangular plate-like shaped dielectric substrate. A ground electrode is arranged on a bottom surface of the substrate. A first resonant line and a second resonant line face the ground electrode through the substrate. Input/output electrodes are connected to the corresponding resonant lines.
