Title: Production of continuous filament mats
Inventor: ROEDERER FRANCOIS
IPC: B65H59/38
Filed: 2004-12-16
Abstract: The invention relates to an installation and method for the preparation of a mat of continuous filaments from at least one roving by projecting same onto a conveyor belt. The invention comprises the following steps consisting in: unwinding from the exterior at least one roving bobbin which is supported on a shaft, the unwinding speed being imposed by a motor that actuates the bobbin directly such that the linear speed of the unwound roving is constant; passing the roving through a nozzle, whereby the roving is passed through an inlet and, subsequently, an outlet of the nozzle, said nozzle also being equipped with a transverse inlet for at least one fluid which is directed mainly towards the outlet of the nozzle, thereby producing a tension towards the bottom of the roving and causing said roving to divide; and projecting the roving-forming filaments onto the conveyor belt using an oscillatory movement. The invention can be used to produce continuous filament mats at great speed with little or no roving breakage, owing to the fact that the roving is only subjected to a low tension which is produced at the nozzle by the divider fluid. ® KIPO & WIPO 2007

Abstract: Methods and circuits are presented for performing high speed write (programming) operations in a dual-bit flash memory array. The method (200) includes, for example, erasing (204) a first and second bit of each cell in the array to a first state, programming (206) the first bit of each cell in the array to a second state, and subsequently programming the second bit of one or more cells in the array to one of the first and second state according to the user's data, resulting in fast write (programming) of those second bits. In addition, the circuit includes, for example, a core cell array (402) having dual-bit flash memory cells configured into a plurality of array portions. The circuit further includes a control circuit (404) configured to selectively block erase one of the array portions, wherein in a first phase of the block erase (204) both first and second bit locations of each dual-bit flash memory cell in the one array portion have sufficient charge removed therefrom to achieve a first state. The control circuit (404) is further configured to, in a second phase (206) of the block erase, supply charge to the first bit location of each dual- bit flash memory cell of the one array portion to enable subsequently fast-write of user's data to the second bit location. ® KIPO & WIPO 2007

Abstract: A frame for reinforcing a display unit and a display unit reinforcing structure having the same are provided to improve durability of the display unit by protecting an LCD panel efficiently with increased strength of a reinforcing frame and improve reception of an antenna by preventing the reinforcing frame from obstructing that the antenna receives an electric signal. A receiving part(42) is received at a bottom side of a case. A connecting part(45) is extended from the receiving part in a direction perpendicular to the receiving part and forms an insertion hole(47) for inserting an antenna(60). A fixing part(48) is extended from the connecting part in the direction perpendicular to the connecting part and is supported by one side of the case. The fixing part forms a shelter(49) to expose the antenna. The shelter is formed along a lengthwise direction of the fixing part in the width corresponding to the width of the antenna. A reinforcement rib(50) is installed between the insertion hole and the shelter along the lengthwise direction of a reinforcing frame(40).
