Measurement system of ferromagnetic particles
A system by which the proportion of ferromagnetic particles in a dielectric medium is measured. A magnetic field is generated by two signals in the medium: a low frequency feed and a relatively high frequency excitation. The feed magnetizes the ferromagnetic particles in the medium to the nonlinear range of the magnetization curve. The excitation is generated so that its spectrum is relatively wide and it is dense with frequency components. The level of the excitation is so high that the magnetic flux density in the medium corresponding to the excitation fluctuates nonlinearly, when the feed is at its peak value or near this. The magnetic field of the medium is measured by a secondary winding, and from the response signal produced by the sensor is detected the part resulting from the magnetic non-linearity, which part is the output signal. In the detection the response is multiplied by the signal, which arises magnetic field and includes the same random fluctuation as the response. The higher the proportion of the ferromagnetic particles in the medium is, the higher the level of the output signal. The secondary winding comprises several portions so that the parasitic voltages caused by the stray capacitances compensate each other. The measurement is real-time and accuracy, because the excitation is a random signal by nature, in which case its spectrum includes, instead of one frequency component, densely frequency components in a certain band.

A device according to the method is suitable for use in an industrial plant and moving vehicles, in which there are interfering fields and the temperature can be high. |

Resistive memory cell array fabricated with unit areas able to be scaled down to 4 F2, where F is minimum feature size in a technology node are described. Memory cells in a pair of cells commonly include a pair of buried sources in the bottom of trenches formed in a silicon substrate. The source line is shared with an adjacent cell. A pair of gate electrodes provides a vertical channel on a sidewall of the trench. A buried word line connects the bottom of the gates on the sidewall overlying the source wherein the word line is looped at the end of the array. A drain, which is self-aligned to the gate, is formed by implantation/doping the surface of the silicon before patterning the trenches. A contact is formed on top of the drain and the resistive memory element is fabrication on the contact. |

System and method for emitting infrared radiation using reflected radiation to enhance emission efficiency
A source assembly (48) configured to generate infrared electromagnetic radiation includes an emitter (60) that emits electromagnetic radiation over an emission solid angle. A portion of the emitted electromagnetic radiation is used in a detection. The portion of the user electromagnetic radiation surrounds the optical path in a usable solid angle. Electromagnetic radiation outside of the usable solid angle is focused back by a reflection assembly (64) onto the emitter to enhance the efficiency of the emitter. |

LED light source device
An LED light source device capable of making the amount of light of an emitting region a predetermined amount of light or more and uniformizing the amount of light is provided. The LED light source device 1 includes an ultraviolet LED array 3 including an LED juxtaposition region R in which LEDs 10 that emit ultraviolet light toward the front are juxtaposed, and a light transmitting member 4 provided on the front side of the LED juxtaposition region R of the ultraviolet LED array 3 so as to be opposed thereto, showing a rectangular parallelepiped outer shape, and formed of a material containing quartz. At a front surface 10a of the LED 10, an emitting surface S surrounded by a marginal portion 11 of a predetermined width H and for emitting the ultraviolet light is provided. Here, when viewed from the front, an end of the light transmitting member 4 is located between inside by ½ of the predetermined width H and outside by ½ of the predetermined width H with respect to an end of the LED juxtaposition region R of the ultraviolet LED array 3. |
