Publication number: 20230211532Abstract: A molding die includes a first mold assembly, a second mold assembly, and a mold core. The first and second mold assemblies are adapted to be clamped together. The mold core defines a molding groove. The molding core is pressed between the first and second mold assemblies to form a molding cavity. The second mold assembly includes a light transmitting area corresponding to the molding cavity, so that the molding cavity will receive incident light through the light transmitting area. In the molding die, the first mold assembly, the second mold assembly, and the mold core cooperate to form the molding cavity, adhesive is injected into the molding cavity, and the molding cavity receives incident light through the light transmitting area, so that curing efficiency of the adhesive is improved, production efficiency is high, shape of molded adhesive is uniform, and product quality is improved.Type: ApplicationFiled: December 28, 2022Publication date: July 6, 2023Inventors: ZHI-QIANG CHEN, WEN-WEN HONG, HUA-ZHONG LIU, BING CHEN, XIANG-YONG LIU, YU-MEI ZHAO

Patent number: 8617538Abstract: Compositions containing an effective amount of mesodermal-like multipotent mammalian mononuclear cells that express both CD34 and M-cadherin cell surface markers are used for preventing, treating or reducing the severity of tissue ischemia or an ischemia associated disorder in a mammal. Such uses may include repopulating an in vivo site with new myocytes and/or vascularizing an ischemic or adjacent tissue. Detection of the level and/or distribution of CD34+/M-cadherin+ mesodermal-like precursor cells in a mammalian tissue sample is used to diagnose, among other things, whether transplantation of autologous CD34+/M-cadherin+ mesodermal-like precursor cells to an ischemic site is indicated.Type: GrantFiled: September 27, 2010Date of Patent: December 31, 2013Assignee: Board of Regents of the University of Texas SystemInventors: Pierre Zoldhelyi, James T. Willerson, Qui Liu, Zhi-Qiang Chen

Publication number: 20130059470Abstract: An electrical connector includes an insulative housing, a first terminal and a second terminal both disposed in the insulative housing. The insulative housing defines a receiving passageway for fixing the terminals and an inserted channel through with the receiving passageway. Each of the first terminal or the second terminal has a base portion located in the receiving passageway, a contacting portion extending into the inserted channel and a tail extending out of the insulative housing. The first terminal further has a encircling portion at an end of the tail of the first terminal. At least, a portion of the tail of the second terminal located in the encircling portion so as that the tail of the second terminal may be held by the tail of the first terminal. Therefore the tails of the two terminals are immovable respectively.Type: ApplicationFiled: August 6, 2012Publication date: March 7, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: ZHI-QIANG CHEN

Publication number: 20120312068Abstract: A stamping tool for stamping a product having an extending portion includes an upper mold having an inserting punch of which a bottom end defines an inclined pressing surface exposed under the upper mold, and a lower mold including an adjusting element, a sliding block, a returning block, a returning bolt and an elastic element. The returning bolt is inserted in the elastic element, and then screwed in the sliding block through the returning block. The sliding block is slidable between the returning block and the adjusting element and has one corner provided with an inclined abutting surface. The inclined pressing surface presses the abutting surface to push the sliding block and the returning bolt to slide towards the adjusting element so as to make the extending portion clipped between the sliding block and the adjusting element for modulating the product.Type: ApplicationFiled: June 10, 2011Publication date: December 13, 2012Applicant: Cheng Uei Precision Industry Co., LTD.Inventors: ZHI-QIANG CHEN, Dong-Hua Tan, Sen-Hsiung Hu
