Abstract:
A system for adjusting radiation target sites dynamically according to the moving states of a target object and for creating a lookup table of the moving states includes a detection chip, a radiation generation device, and a lookup table. The detection chip can be fixed on the target object to detect the current moving state of the target object. The detection chip or the radiation generation device, both configured for wireless signal transmission to each other, can activate or deactivate the radiation emitters of the radiation generation device individually according to the current moving state of the target object and the contents of the lookup table. As the system uses wireless transmission, and the lookup table has recorded the working state of each radiation emitter in each moving state of the target object, radiotherapy can be performed without a large number of tubes or sensors.
Abstract:
A party popper contains: a body which includes two first openings defined on two ends of the body respectively. A flexible push portion is mounted on an end of the body, and a launchable cylinder is slidably accommodated in the body. The body includes a surrounding rib fitted thereon, and the flexible push portion is configured to drive the launchable cylinder to slide until the launchable cylinder is stopped by the surrounding rib. Multiple launchable objects are launched from the launchable cylinder inertially, thus launching the multiple launchable objects safely.
Abstract:
An improved PMA STT MTJ storage element, and a method for forming it, are described. By inserting a suitable oxide layer between the storage and cap layers, improved PMA properties are obtained, increasing the potential for a larger Eb/kT thermal factor as well as a larger MR. Another important advantage is better compatibility with high processing temperatures, potentially facilitating integration with CMOS.
Abstract:
A synthetic antiferromagnetic (SAF) structure for a spintronic device is disclosed and has an AP2/antiferromagnetic (AF) coupling/CoFeB configuration. The SAF structure is thinned to reduce the fringing (Ho) field while maintaining high coercivity. The AP2 reference layer has intrinsic perpendicular magnetic anisotropy (PMA) and induces PMA in a thin CoFeB layer through AF coupling. In one embodiment, AF coupling is improved by inserting a Co dusting layer on top and bottom surfaces of a Ru AF coupling layer. When AP2 is (Co/Ni)4, and CoFeB thickness is 7.5 Angstroms, Ho is reduced to 125 Oe, Hc is 1000 Oe, and a balanced saturation magnetization-thickness product (Mst)=0.99 is achieved. The SAF structure may also be represented as FL2/AF coupling/CoFeB where FL2 is a ferromagnetic layer with intrinsic PMA.
Abstract:
A magnetic element in a spintronic device or serving as a propagation medium in a domain wall motion device is disclosed wherein first and second interfaces of a free layer with a perpendicular Hk enhancing layer and tunnel barrier, respectively, produce enhanced surface perpendicular anisotropy to increase thermal stability in a magnetic tunnel junction. The free layer may be a single layer or a composite and is comprised of a glassing agent that has a first concentration in a middle portion thereof and a second concentration less than the first concentration in regions near first and second interfaces. A CoFeB free layer selectively crystallizes along first and second interfaces but maintains an amorphous character in a middle region containing a glass agent providing the annealing temperature is less than the crystallization temperature of the middle region.
Abstract:
A magnetic element is disclosed wherein first and second interfaces of a free layer with a perpendicular Hk enhancing layer and tunnel barrier, respectively, produce enhanced surface perpendicular anisotropy to increase thermal stability in a magnetic tunnel junction (MTJ). The free layer may be a single layer or a composite and is comprised of one or more glassing agents that have a first concentration in a middle portion thereof and a second concentration less than the first concentration in regions near first and second interfaces. As a result, a CoFeB free layer, for example, selectively crystallizes along first and second interfaces but maintains an amorphous character in a middle region containing a glass agent providing the annealing temperature is less than the crystallization temperature of the middle region. The magnetic element may be part of a spintronic device or serve as a propagation medium in a domain wall motion device.

The present invention provides a vibration-actuated micro mirror device comprising a substrate having a swinging frame and a reflection mirror, and a vibration part having a first and a second vibration structures coupled to the substrate, wherein the first vibration structure is driven to generate a first complex wave formed by a first and a second wave signals while the second vibration structure is driven to generate a second complex wave formed by a third and a fourth wave signals, and the first and the third wave signals are formed with the same frequency and phase while the second and the fourth wave signals are formed with the same frequency but opposite phases. The first and the second complex waves actuate the substrate such that the swinging frame is rotated about a first axis while the reflection mirror is rotated about a second axis.
