  • Patent number: 8617538
    Abstract: 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.

  • Publication number: 20130059470
    Abstract: 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.

  • Publication number: 20120312068
    Abstract: 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.

  • Patent number: 7717753
    Abstract: An electrical connector includes an insulating housing (1) defining a receiving cavity (10) with an opening (101) opened forward and running through a mating face (11). A plurality of terminals are mounted in the insulating housing. A cover (4) defines a space for partly receiving the insulating housing therein, and includes a front wall (43) with an aperture (430) corresponding with the opening (101). A shell (5) is provided for shielding the insulating housing and the cover. A sleeve (3) has a base portion (32) sandwiched between the mating face (11) and the front wall (43) of the cover (4), and a ring (31) projecting forward through the aperture (430), therefore the sleeve can not release from the insulating housing easily.
