Title: Process for depositing metallic conductor paths as electrodes on a channel plate for large-screen flat-panel displays
Inventor: WALTHER MARTEN
IPC: H01J11/02
Filed: 1999-09-10
Granted: 2001-06-23
Abstract: Modern large-screen flat-panel displays known as PDPs and PALCs are provided with a glass plate having a microchannel structure and an address electrode in each channel. Until now, address electrodes have been selectively deposited either directly by means of printing processes or sputtering according to the channel structure or indirectly by selectively etching metal layers deposited electrolessly and/or galvanically over the full area leaving the conductor path structures. To obviate the disadvantages of the known processes, the invention provides that the metallic conductor paths of the address electrodes be deposited selectively only in the electrode areas by means of electroless and/or galvanic deposition processes.

Title: Semiconductor memory device, circuit board mounted with semiconductor memory device, and method for testing interconnection between a semiconductor memory device with a circuit board
Inventor: IKEDA MITSUTAKA
IPC: G01R31/319
Filed: 2000-02-10
Granted: 2001-08-21
Abstract: A semiconductor memory device comprises a detecting unit and a testing unit. The detecting unit detects a plurality of times a state of a predetermined terminal when the power is switched on, and activates the testing unit when all results of the detections show expected values. The device shifts to a connection testing mode by activation of the testing unit, and performs predetermined testing. Therefore, the testing can be performed by causing the device to shift to the testing mode without using terminals dedicated to testing. Besides, a shift to the connection testing mode by activation due to an erroneous operation or power-supply noise is prevented from occurring. In another semiconductor memory device the conversion circuit receives parallel testing patterns via a plurality of input terminals and converts the patterns into serial output patterns. Since the parallel testing patterns are converted into serial output patterns, connection testing can be performed even when the number of output terminals is small. Furthermore, another semiconductor memory device comprises an operation circuit and a conversion circuit. The operation circuit receives parallel testing patterns via a plurality of input terminals, performs a logic operation, and outputs parallel operation result patterns. The conversion circuit receives the parallel operation result patterns and converts the patterns into serial output patterns. The converted output patterns are sequentially output from output terminals. The testing patterns fed to the conversion circuit by the operation circuit can be reduced. Accordingly, the output patterns become shorter, and testing time is reduced.

Patent TW-463056-B (TW)
Title: Image projection system packaged to operate lying flat with a very low profile
Inventor: PETERSON MARK
IPC: G02B26/08
Filed: 2000-05-10
Granted: 2001-11-11
Abstract: An image projection system implemented with a projector engine using a reflective light modulator, preferably a digital micromirror device (DMD), operates lying flat with very low profile on a support table. The invention overcomes the disadvantage of previous DMD projectors that require either tilting all or part of the projection system 45 degrees relative to a support table top or packaging the projection system in a thick box that allows light to impinge on the DMD from above or below its light reflecting surface. This is accomplished with a prism assembly that sets up the correct illumination angles for the DMD and directs imaging (output) light along approximately the same vector as that of illumination (input) light incident to the prism assembly. The illumination light and imaging light do not propagate in a common plane within the prism assembly, but the vectors of the illumination light entering and the imaging light exiting the prism assembly are approximately the same. An alternative preferred embodiment of the prism assembly includes a light escape window through which illumination light reflected by the DMD in its off-state escapes from the prism assembly in a direction away from the projection lens. An implementation using a third prism optically fixed to an output prism or forming an integral part of an enlarged output prism is especially advantageous because it can provide a three-point mounting of the prism assembly to the floor of the interior of the projection system housing.

In another preferred embodiment of this invention, the support fitting is a vertical piece, which has a first horizontal upper surface of the perpendicular support fitting, and a second upper surface of the perpendicular support fitting which is angled slightly upwards. In yet another preferred embodiment of this invention, the support fitting has a vertical piece which extends a fixed distance perpendicular from the rib, and a catch to engage with the heat-resistant block, which extends upward from the end of the vertical piece. The invention is distinguished by the fact that the vertical piece and the catch engage with each other in double groove fashion. In yet another preferred embodiment of this invention, the support fitting is produced by minimizing the proportion of C in the existing cast stainless steel, SUS.
