Title: A new manufacturing process of TFT LCD panel
Inventor: LU CHENG-LI
IPC: B24B13/02
Filed: 2001-11-07
Granted: 2003-09-11
Abstract: This is about an invention of a new manufacturing process of TFT LCD (thin film transistor liquid crystal display) panel, which starts by using a pair of thick glass substrate of thickness at 0.8 mm or above, compared to existing popular processes which use a pair of glass substrate of thickness at 0.7 mm or below; followed by sharpening the thickness of LCD panel to a combined thickness of 0.6 mm to 1.4 mm during the process of its fabrication, by utilizing a ""double-side lapping-polishing technology"". There are two trends which affect the development of manufacturing technology of TFT LCD the advance of manufacturing technology which enable the dimension of glass substrate to become bigger and bigger; and the market needs which require the glass substrate to be thinner and thinner. Yet the two trends are conflicting to each other. The bigger the dimension, the softer the glass substrate (which means easier to curve and bend), therefore more difficult to process. If and when the substrate glass is thinner, it will be even more difficult to process. Dimension of TFT substrates has been developing from 370 mm * 470 mm, 550 mm * 650 mm, 620 mm * 750 mm, 680 mm * 880 mm, 730 mm * 920 mm to over 1000 mm in both length and width. In the meantime market needs for glass substrate has been reducing from 0.7 mm, 0.63 mm to 0.55 mm or even 0.4 mm. Technically it will be extremely difficult to manufacture thin TFT LCD starting from very thin and big glass substrate. Even if it could be achieved, it will inevitably increase the cost of machines and equipments, increase the manufacturing cost, and the yield of good quality products could be low. This invention therefore provides a method to start the manufacturing process from using glass substrate of thickness at 0.8 mm or above, instead of using thinner and thinner substrate, and then to sharpen the panel thickness and polish it after the TFT panel is fabricated, by utilizing a ""double-side lapping-polishing technology"" which is now available in market. The final thickness of the two side substrates of TFT LCD panel could be between 0.6 mm to 1.4 mm. The benefits of this invention are to reduce the cost of manufacturing TFT-LCD panel, to increase yield of quality products and to give flexibility for making LCD panels of different thickness as required by market.

Title: Flexible corrugated hose assembly and connecting process
Inventor: SCHNEIDER AXEL
IPC: F16L25/00
Filed: 2002-01-16
Granted: 2002-11-01
Abstract: For connecting flexible corrugated hoses, which are not provided with fittings, for transporting preferably gaseous media in connection with high-pressure applications, a holder 3 is provided, which receives an exposed end of the corrugated pipe 6 of the flexible corrugated hose 2 and is pressed together with it to form a metallic seal. The metallic seal is achieved by the surface pressure between the interior wall 18 of an element 16 of the holder and the ribs 8 of the corrugated pipe 6. Elastomeric seals 24, 25, as well as a soldering joint 34, if desired, can be provided as aids. However, in connection with a preferred embodiment the required sealing is already achieved by the strong pressure against each other of the metallic exterior of the corrugated pipe 6 and the metallic interior of the element 16. A further element 17 of the holder 3 fixes a section 28 of the sheathing 11 of the flexible corrugated hose 2 in the axial direction, as well as in respect to tilting movements, so that pivot movements of the flexible corrugated hose 2 do not lead to a relative movement between the corrugated pipe 6 and the holder 3, in particular the element 16. Thus, the sealed area remains unaffected, even in case of mechanical tensile or bending stresses of the flexible corrugated hose assembly 1.

Title: Flash and brightness control method of LED using positive and negative pulse modulation
Inventor: LIOU JUNG-CHI
IPC: H05B41/38
Filed: 2002-02-08
Granted: 2003-03-01
Abstract: There is provided a flash and brightness control method of LED using positive and negative pulse modulation, which is applied in the lamplight control of the LED lamp for achieving the purpose of varying lamplight display effect. The method comprises a LED lighting procedure controller in cooperation with at least one set of electronic switches for applying voltage on terminals A and B of the LED lamp series. When A is positive and B is negative (positive cycle), the forward LED (D1) is turned on. When A is negative and B is positive (negative cycle), the backward LED (D2) is turned on. Therefore, by applying voltage varying between positive and negative cycles to the terminals A and B, the two sets of LEDs are turned on, respectively. With the alternation of positive and negative cycles, it is able to achieve the effect of turning on the LEDs and alternately turning the two LEDs for flashing. Furthermore, the present method can be used to control the number of voltage pulse of high-frequency power for changing the effective electric power asserted on the LED, thereby achieving the effect of controlling the LED brightness.
