Abstract: A data driver for driving pixels in an active matrix organic LED (AMOLED) is provided the data driver includes a plurality of converters configured to convert to analog current signal digital voltage signals in order to drive the pixels to emit light. Each converter has a plurality of current mirror devices configured to generate mirrored current signals by inputting two control signals. Meanwhile, the mirrored current signals can maintain their preciseness even if deviation of the characteristics of the transistors implanted within the current mirror devices occurs during fabricating.
Abstract: A method and apparatus that produces shaped and laminate articles and recovers the excess material or flash as a part of the manufacturing process. The apparatus uses a combination of rotary die and anvil roller assemblies in successive multiple stations to cut and separate each raw material into final product portions and recyclable flash portions as each raw material enters the apparatus. The apparatus separately reclaims each raw material flash portion and delivers the flash of each material in a recyclable form to an auxiliary recycling operation. In recovering the flash, the apparatus does not adversely affect the speed or quality of production of the final shaped or laminated product. To ease removal of the flash, the apparatus applies lubricant to the blades of the rotary die. To avoid damage to web material, the apparatus uses vacuum belts to convey the web material and web product through the apparatus.

Abstract: A pod unit including a pod housing (1) and an assembly unit (6), a so called seating, for the pod housing (1), wherein the seating (6) has a lower portion (6A) and an upper portion (6F) as well as a base (15) for the installation of the pod housing (1) which comprises a lower casing portion (1A) for the accommodation of a propulsion unit (2, 3, 4), an intermediate portion (1B) comprising air ducts (9, 10), and an upper portion (1C), which is fixedly connected to a steering engine (14, 18, 19), with a gear ring (14) to be fixed at said base (15). A cooling system comprising having at least one fan (7) is mounted within the seating.
Abstract: The present invention relates to a hydraulic DEVICE having a valve housing (1) with a movable valve body (2) arranged inside the valve housing, a hydraulic cylinder with at least a hydraulic chamber (115), and at least a control mechanism (4) for the control of said movable valve body (2), the valve body (2) is substantially sleeve-shaped and arranged inside an annular space (128) in the valve housing (1), and said valve body (2) is provided with a plurality of apertures (250, 251, 252; 206, 202) to make a flow of hydraulic liquid possible in the radial direction through the valve body (2).
Abstract: A propulsion system for ships having an impeller (13, 14), a stator shell (1), and an impeller housing (3) for achieving a water jet, a shaft (11, 12) for the propulsion of the impeller (13), and a bearing arrangement for the shaft (11, 12) in the stator shell (1), and preferably a sealing (15) of the shaft (11, 12) in the impeller housing (3), wherein the shaft (11, 12) consists of a light weight shaft, which has considerably lower bending rigidity than a homogenous, conventional steel shaft, and the driving force is transmitted via at least one non-flexible coupling (11B, 12A) and via the bearing arrangement which is rigid as to bending and handles the axial load, to the stator shell (1), such that a high power density is achieved.
