An EL element is provided in which a conjugate polymer that has a polythiophene derivative, a polyaniline derivative, a polypyrrole derivative or a polyfuran derivative as a fundamental skeleton and is soluble in an organic solvent is oxidized in its main chain with a dopant of an electron-accepting organic molecule that does not contain an acid component, and the doped conjugate polymer is used as a material to form a hole injecting layer. The polymer, being soluble in an organic solvent, can be formed in film even on a substrate high in the water repellency; that is, it can be easily formed in film on a TFT substrate and the like indispensable for an active matrix display device. Furthermore, since a dopant that does not contain an acid component is used, influence on an organic thin film and an electrode that are in contact with the hole injecting layer can be suppressed to the minimum level.

The invention provides a balloon catheter. In the balloon catheter in which the guide wire and the balloon catheter are integrated, the step between the coil part of the guide wire and the front end part of the balloon catheter can be prevented, and the connection can be made smoothly without the need for The additional element can fully utilize the characteristics of the leading end portion of the wire. The balloon catheter (1) includes a protruding portion (84) extending from the rear end of the distal coil portion (90) by an inner coil (81) disposed inside the distal coil portion (90) and surrounding a mandrel (71) and the leading end opening (42) of the guide wire lumen (41) is provided at the leading end of the catheter body (10), and the protrusion (84) is inserted into the interior of the leading end opening (42).

According to one embodiment, a single-sided multilayered information recording medium having recording layers, wherein an emboss management zone, an inner recordable management zone, a data area, and an outer recordable management zone are sequentially arranged from an inner side of each of the recording layers, and a burst-cutting area is arranged inward of the emboss management zone in any one of the recording layers.

The invention relates to a controllable vibration damper (1), in particular for a vehicle body, comprising a cylindrical tube (10) which has a hydraulic fluid that is sealed in the cylindrical tube, a piston (2) which is axially movable within the cylindrical tube (10) along a cylindrical tube axis (A) and which divides the cylindrical tube (10) into two work chambers (11, 21), and a piston rod (3) which is oriented parallel to the cylindrical tube axis (A) and which is connected to the piston (2) at one end, multiple fluid passages (12, 22) from one work chamber (11, 21) to the other work chamber (21, 11) being provided in the piston. A first valve assembly (13) for damping the piston movement in a first actuation direction (R1) is arranged in a first fluid passage (12), and a second valve assembly (23) for damping the piston movement in a second actuation direction (R2) is arranged in a second fluid passage (22), each valve assembly (13, 23) having at least one valve disk (14, 24) which sits on a valve seat (15, 25) in a closed valve position and is at least partly removed from the valve seat (15, 25) in an open valve position. Each valve assembly (13, 23) comprises a pilot control chamber (16, 26), and a pressure in the pilot control chamber (16, 26) urges the valve disk (14, 24) into the closed valve position, the pressure in each of the pilot control chambers (16, 26) being adjustable. According to the invention, one of the pilot control chambers (16, 26) is delimited by a base (4), a cylindrical lateral wall (5) which is stationary relative to the base (4) and which is coaxial to the cylindrical tube axis (A), and a dimensionally stable cover (6) which can be moved parallel to the cylindrical tube axis (A) in a radial manner within the cylindrical lateral wall (5).

The invention relates to a flat steel semi-finished product (1), comprising a first layer (1.1) made of a martensitic steel alloy, which has a tensile strength of > 1200 MPa and / or a hardness of > 370HV10, and at least one second layer (1.2, 1.2') made of a soft steel alloy, which is connected to the first layer (1.1) over the full surface area and in a material-to-material manner, having a tensile strength of < 600 MPa and / or a hardness of < 190 HV10. The invention further relates to a method for producing a component from the flat steel semi-finished product, and to a corresponding use.

The invention discloses a flexible DC short-circuit fault protection method based on a thyristor chain and a superconducting current limiter. The converter used in the flexible DC power transmission system is a modular multi-level converter based on cascaded half-bridge sub-modules: ABC three-phase structure, each phase includes an upper bridge arm and a lower bridge arm, each bridge arm is composed of several half-bridge sub-modules and a bridge arm inductor; the output port of the modular multi-level converter AC side is connected in parallel with a thyristor A superconducting current limiter is connected in series with each of the three-phase lines on the AC side of the modular multilevel converter; the upper ends of the three-phase upper arms of the modular multilevel converter are short-circuited and connected to the DC side through the first mechanical switch , the lower end of the three-phase lower bridge arm is short-circuited and then connected to the DC side through the second mechanical switch. The protection method realizes the current isolation of the AC and DC sides under fault conditions by opening the thyristor chain and reduces the fault current of the DC side to zero, and limits the fault current of the AC side through the superconducting current limiter, thereby realizing the DC short-circuit fault protection of the flexible DC transmission system.
