Patent number: 9227354Abstract: Disclosed are a feedblock multiplier with thickness gradient variation, a feedblock system, a method, and multilayer structure made by the method. The feedblock multiplier combines the functionalities of feedblock and multiplier conventionally used for producing the multilayer structure. The feedblock multiplier includes an input section for feeding fluid materials. A feedblock section is included for dividing the fluid delivered into multiple channels correspondingly. The fluids in the channels are segmented into two or more fluid segments by a segmenting section. The each fluid segment is delivered through corresponding channel-conversion section with thickness-gradient variation in the feedblock multiplier. Each channel-conversion section includes multiple channels with configurable positions. The fluids are then combined in a multiplier section for producing the multilayer structure with overlapped layers. The multilayer structure is outputted from an extruding section.Type: GrantFiled: May 6, 2012Date of Patent: January 5, 2016Assignee: EXTEND OPTRONICS CORP.Inventors: Jen-Huai Chang, Wen-Cheng Wu, Chao-Ying Lin

Publication number: 20110089025Abstract: The present invention relates to a method for manufacturing a chip resistor having a low resistance. The method includes the following steps: (a) providing a substrate having a top surface; (b) sputtering a conducting layer directly on the top surface of the substrate, so that the conducting layer and the substrate contact each other, wherein the material of the conducting layer comprises nickel or copper; and (c) plating at least one metal layer directly on the conducting layer, so that the metal layer and the conducting layer contact each other, wherein the material of the metal layer comprises nickel or copper, and the conducting layer and the metal layer provide a resistive layer. As a result, the resistive layer has a precise pattern, and the duration of sputtering is reduced, so the yield rate and the efficiency are improved and the manufacturing cost is cut down.Type: ApplicationFiled: October 20, 2009Publication date: April 21, 2011Applicant: YAGEO CORPORATIONInventors: Chih-Chung Yang, Mei-Ling Lin, Ian-Wei Chian, Wen-Cheng Wu, Wen-Hsiang Kong, Tsai-Hu Chen
