TL;DR: In this paper, a conductor wire core for a power cable, consisting of an inner-layer molded wire and an outer-layer molding wire, was proposed. And the wire core has a smooth surface so that the risk of insulation breakdown is reduced.
Abstract: The invention relates to a conductor wire core for a novel power cable, comprising an inner-layer molded wire and an outer-layer molded wire The molded wires are produced by a molded wire filament drawing machine of which a molded wire filament drawing mold has the finish of less than 5; the single filaments of the inner-layer molded wire adopt round wires or combined round wires formed by combining 2 to 6 filaments with fan-shaped cross sections; the single filaments of the outer-layer molded wire are shaped like tiles and spirally stranded towards the same direction by using a frame-type strander; and the stranded wire core has a round cross section The external diameter of the conductor wire core can be effectively reduced, and the consumption of outer-layer materials of the power cable can be saved The conductor wire core has a smooth surface so that the risk of insulation breakdown is reduced In addition, the rigidity and bend radius of the power cable are reduced so that the related power cable can be laid more conveniently

Abstract: The invention discloses a bending formation method of a small-curvature bending radius L type thin-wall aluminum alloy bent pipe. Two ends of the bent inner side of a long pipe blank of an aluminum alloy thin-wall pipe blank are grooved by 35-45 degrees; a protective agent is coated at the external of the pipe blank; oily molybdenum disulfide is sprayed in the semi-cylindrical surface of an area from the from part of the bent inner side of the pipe blank to the front part pi D, so that a material on the bent inner side of the pipe is facilitated to flow and to improve wrinkling; a traditional polyurethane round bar is replaced; multiple polyurethane cylinder blocks are filled in the pushed end of the pipe blank; and compared with an integral polyurethane filler rod, the taking out is easier after formation, and the forming efficiency is improved. Meanwhile, the polyurethane cylinder blocks with proper hardness, thickness and diameter facilitate internal support of the bent pipe, and are not liable to generate wrinkles on the bent inner side; and the jacking force of a core head is reinforced during forming to supply enough internal pressure into the pipe through a filler to force a lot of materials to flow to the front groove so as to prevent wrinkling to form the qualified small-curvature bending radius L type thin-wall aluminum alloy pipe.

TL;DR: In this article, a small-diameter coaxial cable harness with a cylindrical shape and a waterproofing section 23 is mounted on the uniting section at a location where an introduction position to the first case 1 and the second case 2 is mounted.
Abstract: PROBLEM TO BE SOLVED: To provide a small-diameter coaxial cable harness capable of connecting cases with excellent waterproofness maintained, and excellent in miniaturization of a bending radius and durability against repetitive bending. SOLUTION: In the small-diameter coaxial cable harness 11 where a plurality of small-diameter coaxial cables 12 are bundled and a first case 1 and a second case 2 capable of changing these position relations are connected with each other, a uniting section 10 for bundling the small-diameter coaxial cables 12 is in a cylindrical shape, and a waterproofing section 23 is watertightly mounted on the uniting section 10 at a location where an introduction position to the first case 1 and the second case 2 is mounted. The uniting section 10 is made of a tube 21, a gap against the waterproofing section 23 is covered with the tube 21, and an end section of the tube 21 is watertightly connected with the waterproofing section 23.

TL;DR: In this paper, the authors introduced two important types of testing loads (i.e., entire reverse of bend and torsion with several cycles) to investigate the optical and flexible characteristics of film-type cholesteric liquid crystal displays (ChLCDs).
Abstract: Given that the induced stress resulting from fatigue bending or torsional loads increases with increasing display thickness, the long-term mechanical reliability of display modules in soft electronics has attracted considerable attention. Therefore, understanding the related failure mechanism and stress contour distribution in the display structure is important and necessary, particularly in torsional load application. This study introduces two important types of testing loads (i.e., entire reverse of bend and torsion with several cycles) to investigate the optical and flexible characteristics of film-type cholesteric liquid crystal displays (ChLCDs). The bending radius and the torsion angle used are 20 mm and ${\pm}{\hbox{10}}^{\circ}$ , respectively. The stress contour and possible failure location of the testing specimens are obtained by using non-linear finite element analysis (FEA). Results indicate that a significant optical characteristic decay occurs beyond 1000 testing times. In 11,000 cycles of fatigue bending and torsion tests, 45% and 55% decay change rates, respectively, are obtained for the National Television System Committee. Accordingly, a worse situation occurs at the torsion test. This phenomenon is attributed to a two-direction bend torsion exerted on the tested ChLCD. The foregoing behavior is validated by using FEA.

TL;DR: In this article, a pipe is formed in at least one section to a freely cantilevered bend and the pipe sections which form the bend meet at an acute angle, the bend including a change of direction of 180 degrees.
Abstract: The exchanger has a radial fan (10) which is surrounded by a burner (12). It also has a pipe (14) which is formed in at least one section to a freely cantilevered bend (16). Preferably the bend has an enlarged cross-section and the pipe sections which form the bend meet at an acute angle, the bend including a change of direction of 180 degrees . The preferred cross-section of the pipe in the region of the bend is an oval shape.
