Granted: 2001-02-11
Abstract: A production method with reduced cavity in polysilicon etching comprises providing a to-be-etched polysilicon layer, the surface of which can have a metal silicide for improving electric properties, on a silicon substrate; sequentially forming a TEOS layer and an antireflective BARC layer on the surface of the polysilicon layer, the surface of the BARC layer having a photoresist layer with a defined pattern; using the photoresist as a mask, using O2, N2 plasma to etch the BARC layer, and using CHF3, CF4, Ar, N2 plasma to etch the BARC layer; using the etched BARC layer and TEOS layer as the etching mask of the polysilicon layer after the removal of the photoresist. In this invention, since the BARC layer and the TEOS layer are defined with a pattern using a two-stage etching method using a highly selective reactive gas, therefore the defect opening on the surface of the BARC layer will not transitionally be etched to the polysilicon layer and damage the underneath element during etching of the polysilicon.

Title: Liquid crystal display panel, liquid crystal display device and composite optical element
Inventor: OHSUMI KAZUMASA
IPC: G02B5/02
Filed: 1999-04-06
Granted: 2004-01-01
Abstract: A liquid crystal display device 10 includes a side light type surface light source device 11 and a liquid crystal display panel 12 installed on the side light type surface light source device 11. The illuminating light emitted from a fluorescent lamp 8 is guided to a light guide plate 13 through an incident surface 13A directly or after being reflected by a reflection mirror 9. In the inner transmission process, the light emitted from an emission surface 13C is first emitted out obliquely. A light scattering figure formed on the emission surface 13C can promote the emission. A light control surface provided a back surface 13B corrects the directivity as a front surface direction with respect to the surface in parallel with the incident surface 13A. The output illumination light corrects the directivity as a front surface direction by a prism 21 mounted on the liquid crystal display panel 12 with respect to the surface vertical with the incident surface 13A. The prism 21 provides a composite optical device integrally formed with a polarization film 16. The light component passing through the polarization film 16 is supplied to liquid crystal 18. The light outputted from the liquid crystal 18 emits to a polarization film 20. The light component passing through the polarization surface corresponding to the polarization film 20 passes through the polarization film 20 for output to outside. The output density distribution is controlled based on the voltage applied to the transparent electrodes, thereby providing variable display images. The prism 21 can also be connected to the polarization separation sheet member, light expansion sheet member or the like to provide a composite optical device, thereby avoiding damage or deformation of protrusion rows, assuring illumination quality and thus assuring the high quality of liquid crystal display device.

Abstract: A character font generation apparatus generates a font of a character for the output of the character to an output unit (15). First, whether the character specified through the operation of an input unit (14) can be output in a desired font based on a predetermined resolution of the output unit (15) or not is determined. If the result of determination indicates ""output not allowed"", a stroke of the character is omitted to reduce the size of the character to allow the correct output according to the predetermined resolution. The stroke omission is performed with reference to contents of a DB (database) memory (12) storing various information necessary for the character font generation and a priority determination rule (131) indicating various information for determining the priority of stroke omission, so as to maintain the balance of the character such as center and centroid thereof and to preserve the shape (contour) of the character.

Title: Process and apparatus for removing sulfur dioxide from flue gases
Inventor: BROWN GREGORY N
IPC: B01D53/50
Filed: 1999-08-31
Granted: 2001-11-01
Abstract: A wet flue gas desulfurization process and apparatus (10) for removing sulfur dioxide from flue gases. The process utilizes an ammonium sulfate scrubbing solution (22) into which is injected ammonia diluted with water and oxygen, which react with sulfur dioxide absorbed in the solution (22) to produce ammonium sulfate as a valuable byproduct. The scrubbing solution contacts the flue gases and absorbs sulfur dioxide within an absorber (12) of a flue gas scrubbing apparatus (10), and is then accumulated in a vessel (18) having a bottom wall (36) and a side wall that defines a cross-section of the vessel (18). Localized high pH and ammonium sulfite levels within the scrubbing solution (22) are avoided by introducing the dilute ammonia at the bottom wall (36) of the vessel (18) so that the fluid is uniformly dispersed across the cross-section of the vessel (18) prior to becoming intermixed with the remainder of the scrubbing solution (22) in the vessel (18) and prior ot the scrubbing solution (22) being recirculated to the absorber (12) of the apparatus (10). The dilute ammonia is preferably formed by mixing air with ammonia and water, which are then simultaneously dispersed near the bottom wall (36) of the vessel (18) through a plurality of conduits (34) that extend across the cross-section of the vessel (18) and inject the mixture toward the bottom wall (36).
