Publication number: 20240107888Abstract: Provided are a piezoelectric composite material, an actuator, and a preparation method of the actuator, relating to the technical field of piezoelectric composite material actuators. The piezoelectric composite material includes an upper interdigital electrode layer, a piezoelectric fiber composite layer and a lower interdigital electrode layer which are arranged in sequence from top to bottom. The upper interdigital electrode layer, the piezoelectric fiber composite layer and the lower interdigital electrode layer each are of a parallelogram structure. A piezoelectric ceramic fiber array is embedded on the piezoelectric fiber composite layer; and the piezoelectric ceramic fiber array is of a parallelogram structure. By arranging the piezoelectric ceramic fiber array of the parallelogram structure, the effective area of an actuator can be increased, and then the actuation performance of the actuator can be improved.Type: ApplicationFiled: April 27, 2023Publication date: March 28, 2024Applicant: NANJING UNIVERSITY OF AERONAUTICS AND ASTRONAUTICSInventors: Hongli JI, Jinhao QIU, Chao ZHANG, Congchong TAO, Yuemin DU, Jiao QU

Publication number: 20200140856Abstract: A cell model for in vitro evaluation of compound-induced skin sensitization and a constructing method therefor. The method for constructing the cell model comprises the steps of: designing and constructing an sgRNA expression vector based on CRISPR/Cas9 vector system; designing and constructing a homologous recombinant vector capable of knocking a reporter gene linked to a self-cleaving peptide sequence into a specific site of the expression frame of the HMOX1 gene; co-transfecting the homologous recombinant vector, an hCas9 plasmid and the sgRNA expression vector into a cell, and carrying out monoclonal expansion to obtain the cell model. The present invention obtains a HaCaT cell model in which a luciferase gene is knocked in before the stop codon of the HMOX1 gene by combination of CRISPR/CAS9 and a monoclonal cell technique. The cell model realizes synchronous expression of the luciferase gene and the HMOX1 gene, thereby effectively distinguishing sensitizing compounds from non-sensitizing compounds.Type: ApplicationFiled: October 29, 2018Publication date: May 7, 2020Applicant: South China University Of TechnologyInventors: Lizhen HUANG, Guorui ZHONG, Haojian LI, Shuilin XIE, Shihui PANG, Jing BAI, Changsheng HE, Xinyi DU, Qixiao ZHANG, Haijie WANG, Hongli DU

Patent number: 7640836Abstract: Web processing method and apparatus (30, 300) is provided for high speed, extremely accurate die cutting or lamination operations. Processing station (32,300) includes a vacuum hold down plate (32,308) which receives and holds an image bearing incremental segment of the web. In feed and out feed tension on the web is released while a segment of the web is held by the hold down plate. The hold down plate with a segment of the web thereon is selectively shifted about X, Y, and ? axes as required to bring the image on the web segment into alignment with a web processing component at the processing station.Type: GrantFiled: July 13, 2000Date of Patent: January 5, 2010Assignee: Preco Industries, Inc.Inventors: Charles C. Raney, Hongli Du, John T. Pierson, Jr.

Patent number: 7181367Abstract: Process control systems may include one or more diagnostic systems and/or processes. In particular implementations, a diagnostic system and process for a field instrument may include the ability to divide a signal input range into a plurality of zones with respect to an input axis or a time axis, measure input response characteristics for a zone with the field instrument, and store measurement data points for the zone in memory of the field instrument. The diagnostic system and process may also include the ability to transmit the measurement data points for the zone to a host application and, while transmitting the measurement data points for the zone, measure input response characteristics for a second zone with the field instrument.Type: GrantFiled: May 26, 2005Date of Patent: February 20, 2007Assignees: Dresser, Inc., Yokogawa Electric CorporationInventors: Yoji Saito, Kazuhiro Hashizumi, Alex Legere, Hongli Du

Patent number: 6666122Abstract: High speed, extremely accurate web or sheet-fed segment die cutting or lamination apparatus (30, 300) has a processing station (32, 300), which receives a sheet or web segment, and is provided with a vacuum hold-down plate (142, 306) for holding initially fed segments (38). The plate is shiftable as necessary along orthogonal X-Y axes in the plane of the segment (38), and/or is rotatable about a &thgr; axis transverse to the segment plane. Plate movement is effected by a series of aligned, translatable eccentric drive units (178-182, 346-350). Segments (38) carry positioning fiducials (44) that are compared with fixed reference indicia (250, 252) in the station (32, 300). The comparison data is used by a controller (254) to generate the plate movement information used in simultaneous operation of the associated plate drive units (178-182, 346-350).Type: GrantFiled: August 30, 2001Date of Patent: December 23, 2003Assignee: Preco Industries, Inc.Inventors: Charles C. Raney, Hongli Du, John T. Pierson, Jr.
