Publication number: 20240084051Abstract: Disclosed are support-activators and catalyst compositions comprising the support-activators for polymerizing olefins in which the support-activator includes clay heteroadduct, prepare from a colloidal phyllosilicate such as a colloidal smectite clay, which is chemically-modified with a heterocoagulation agent. By limiting the amount of heterocoagulation reagent relative to the colloidal smectite clay as described herein, the smectite heteroadduct support-activator is a porous and amorphous solid which can be readily isolated from the resulting slurry by a conventional filtration process, and which can activate metallocenes and related catalysts toward olefin polymerization. Related compositions and processes are disclosed.Type: ApplicationFiled: October 11, 2023Publication date: March 14, 2024Applicant: Formosa Plastics Corporation, U.S.A.Inventors: Michael D. Jensen, Kevin Chung, Daoyong Wang, Wei-Chun Shih, Guangxue Xu, Chih-Jian Chen, Charles R. Johnson, II, Mary Lou Cowen

Publication number: 20240088147Abstract: An integrated circuit includes a first terminal-conductor, a second terminal-conductor, and a gate-conductor between the first terminal-conductor and the second terminal-conductor. The first terminal-conductor intersects both an active-region structure and a power rail. The second terminal-conductor intersects the active-region structure without intersecting the power rail. The gate-conductor intersects the active-region structure and is adjacent to the first terminal-conductor and the second terminal-conductor. A first width of the first terminal-conductor is larger than a second width of the second terminal-conductor by a predetermined amount.Type: ApplicationFiled: January 9, 2023Publication date: March 14, 2024Inventors: XinYong WANG, Cun Cun CHEN, Ying HUANG, Chih-Liang CHEN, Li-Chun TIEN

Publication number: 20240059515Abstract: A cardboard conveyor device forms sub negative pressure regions communicative to a main negative pressure region by using wind shield structures of a plate body structure, thus saving power consumption of an aspirator. The plate body structure is for example formed by three plate bodies, the plate body of a middle layer has air holes, the plate body of an upper layer has first interval spaces penetrating the plate body of the upper layer, and the plate body of a lower layer has second interval spaces penetrating the plate body of the lower layer. Each of the first interval spaces is communicative to the corresponding second interval space via the corresponding air holes, and the second interval spaces are communicative to the main negative pressure region. Thus, the sub negative pressure regions can provide a negative pressure to the cardboard being conveyed.Type: ApplicationFiled: October 19, 2022Publication date: February 22, 2024Inventor: CHIH-WANG CHEN
