Abstract: Embodiments of present invention provide a magnetic tunnel junction (MTJ) structure. The MTJ structure includes a MTJ stack, the MTJ stack including a tunnel barrier layer on a reference layer and a free layer on the tunnel barrier layer, wherein the free layer includes multiple sub free layers, the multiple sub free layers being multiple ferromagnetic strips placed parallel to each other on the tunnel barrier layer, the multiple ferromagnetic strips having respective first ends connected to a first electrode and respective second ends connected to a second electrode. A method of forming the MTJ structure is also provided.

Abstract: An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.

Abstract: A memory device and method of forming a projection liner under a mushroom phase change memory device with sidewall electrode process scheme to provide self-aligned patterning of resistive projection liner during sidewall electrode formation.

Abstract: A one-touch data transmission module includes a data receiving unit, for receiving a transmission datum sent by a physiological data analyzer; a control unit, electrically connected to the data receiving unit, for obtaining the transmission datum received by the data receiving unit; a memory unit, electrically connected to the control unit, for storing the transmission datum; a communication unit, electrically connected to the control unit, for sending the transmission datum to a designated place; a power unit, for supplying power to the data receiving unit, the memory unit and the communication unit; a trigger button, electrically connected to the control unit, for triggering the control unit to start the data receiving unit to receive the transmission datum, the received transmission datum being send by the communication unit. The data transmission module provides the functions of simple operation and real-time data transmission for an elderly person.

Abstract: A coaxial connector (100) adapted for mating with a mating connector (200) includes a bracket (10), and a clasping portion (40) clasping the mating connector. The bracket has a central contact (30) retained in the bracket for electrically connecting with the mating connector. The clasping portion includes a base flange (41) and a number of claw portions (42) extending from the base flange. Each claw portion has an engaging portion (421) for engaging with the mating connector. The coaxial connector further includes a resilient ring (70) mounted on the engaging portion of the clasping portion to strengthen the engagement between the engaging portion and the mating connector. The coaxial connector includes a conductive resilient sealing ring (60) mounted between the bracket and the mating connector.

Abstract: An RF connector (1) for mating with a plug connector (3) has an outer housing (1) defining an axial bore (101) for receiving the plug connector, a locking member (14) received in the axial bore, an insulative body (12) retained in the axial bore of the outer housing and defining an axial hole (121), a terminal (13) assembled to the axial hole of the insulative body, a first sealing ring (15) and a second sealing ring (16). The first sealing ring is assembled between an interior surface of the outer housing and an outer surface of the locking member. The second sealing ring is disposed around an inner surface of locking member for resisting against an outer surface of the plug connector when the plug connector is inserted in the RF connector.
