Title: Image data encoding apparatus
Inventor: OKADA MASAKI
IPC: H04N19/60
Filed: 1998-05-11
Granted: 1999-12-11
Abstract: An image data encoding apparatus performs a two-step process to expand and compress digital image data. The apparatus includes a transform unit for performing orthogonal transform of the image data in a block-by-block manner and generating transform coefficient data. In the first step of the encoding step, a quantizer quantizes the transform coefficient data using a first quantization coefficient to generate first code data. A coefficient operation unit receives the first code data and computes a second quantization coefficient for determining an optimal compression rate of the image data. In the second step of the encoding process, the quantizer receives the second quantization coefficient and quantizes the transform coefficient data to generate second code data. The transform coefficient data is stored in a memory. By optimally compressing the image data, a high image data compression rate is achieved, which allows a greater number of compressed images to be stored. Also, by pipelining the encoding and decoding process, image processing time is decreased.

Title: Cassette and indicia system
Inventor: WILLIAMS HAL
IPC: A61L2/18
Filed: 1998-09-03
Granted: 2001-03-01
Abstract: A method for delivering liquids is disclosed wherein a quantity of the liquid is provided within a cell within a cassette. The cassette is received within a sleeve having an open end. A flap at the open end of the sleeve extends inwardly through the open end between the sleeve and cassette to abut a lip on the cassette and hold the cassette therein. Impingement of the flap pushes the flap away from the lip to allow the cassette to move out of the sleeve. A label mounted within the sleeve rotates between a viewable position where it is visible through a window in the sleeve and a retracted position away from the window. Extraction and reinsertion of the cassette into the sleeve moves the label from the viewable to the non-viewable position.

Title: A manufacturing method of front plate of plasma display panel
Inventor: SUNG WEN-FA
IPC: H01J9/02
Filed: 1998-07-13
Granted: 2000-06-21
Abstract: A traditional manufacturing method of plasma display panel uses 3 times the photo mask to proceed the exposure developing programs, which are transparent electrode photo-mask, metal electrode photo-mask, and photo-covered photo-mask. Following the proceeding of manufacturing process, different materials gradually form in the base plate. The alignment mark pattern for exposure machine on alignment also is transferred to the upper material layer. Even so, the exposure machine cannot correctly detect the alignment mark but proceed in the auto-alignment when the alignment mark is transferred to the higher transparent material, such as to the transparent electrode. Before, only the manual alignment is available, therefore, it has a long operating time and was not advantageous to the production efficiency. Manual alignment worsens precision to impart on the component compatibility. By the change of steps and back exposure technique, this invention promotes front plate manufacturing of plasma display panel to decrease the number of photo-mask usage and promote the precise effect of exposure developing. Firstly, the net printing program or the first photo-mask to a photo-covered layer proceeds the exposure-developing program and defines the photo-covered layer pattern, including the gap pattern in photo-covered band and transparent electrode. Next, the photo-covered layer pattern isused as photo-mask. A back exposure, developing program, and an etching program is applied to form the multiple electrodes to the transparent electrode on the surface of base plate. Finally, a second photo mask proceeds the other exposure, developing, and etching program to define multiple electrodes to metal electrode opposite to the transparent electrode.

Title: Modification of thermoplastic vulcanizates with a thermoplastic random copolymer of ethylene
Inventor: FINERMAN TERRY M
IPC: C08L23/08
Filed: 1998-09-30
Granted: 2001-10-21
Abstract: Random thermoplastic ethylene copolymers can be used to increase the elongation to break and toughness of thermoplastic vulcanizates. Polypropylene is a preferred thermoplastic phase. The rubber can be olefinic rubbers, Random thermoplastic ethylene copolymers are different from Ziegler-Natta ethylene copolymers as the compositional heterogeneity of the copolymer is greater with Ziegler-Natta copolymers. This difference results in substantial differences in properties (elongation to break and toughness) between thermoplastic vulcanizates modified with random thermoplastic ethylene and those modified with Ziegler-Natta ethylene copolymers. An increase in elongation to break results in greater extensibility in the articles made from a thermoplastic vulcanizate.
