摘要:
A method of manufacturing a non-shrinkage ceramic substrate comprises preparing a plurality of green sheets; forming internal electrodes and conductive vias in the respective green sheets; laminating the plurality of green sheets to form a multilayer ceramic substrate; forming a constrained layer on the top and bottom surfaces of the multilayer ceramic substrate by using one or more methods selected from the group consisting of an ALD (Atomic Layer Deposition) method, a sputtering method, a CVD (Chemical Vapor Deposition) method, and a sol-gel method, the constrained layer not being fired at the firing temperature of the green sheet; firing the resultant structure at the firing temperature of the green sheet; and removing the constrained layer.

Provided herein is a plasma display panel. The plasma display panel comprises a front substrate, a rear substrate opposite to the front substrate and having address electrodes formed thereon, a lattice-shaped partition wall formed between the front substrate and the rear substrate, a phosphor applied to a discharge space partitioned by the partition wall, and a plurality of scanning electrodes and common electrodes formed in intersection regions of the partition wall and extending perpendicular to the front substrate. The plasma display panel has a sufficient aperture ratio, and thus has enhanced light emitting efficiency. The scanning electrodes and the common electrodes formed in the intersection regions of the partition walls have a vertical construction, thereby effectively preventing the phosphor from being damaged by the plasma. Discharge uniformly occurs at the outer periphery of the discharge cell, thereby inducing effective excitation of the phosphor.

Disclosed herein is a laminated filter with improved stop band attenuation, which is adopted in devices using a radio frequency, such as communication systems and/or broadcasting systems. The laminated filter forms cross capacitive coupling as feeding lines of input lead and/or output lead are coupled to a resonator pattern, and enhances an attenuation characteristic of stop band. Also, the laminated filter is minimized if feeding lines of the input lead and output lead are aligned in different layers, and the positions of the attenuation poles are easily controlled by adjusting the feeding line length.

Disclosed is a flash memory cell and method of manufacturing the same, and programming/erasing/reading method thereof. The flash memory cell comprises a first tunnel oxide film formed at a given region of a semiconductor substrate, a first floating gate formed on the first tunnel oxide film, a second tunnel oxide film formed over the semiconductor substrate and along one sidewall of the first floating gate, a second floating g ate isolated from the first floating gate while contacting the second tunnel oxide film, a dielectric film formed on the first floating gate and the second floating gate, a control gate formed on the dielectric film, a first junction region formed in the semiconductor substrate below one side of the second tunnel oxide film, and a second junction region formed in the semiconductor substrate below one side of the first tunnel oxide film. Therefore, the present invention can implement 2-bit cell or 3-bit cell of a high density using the existing process technology. Further, it can reduce the manufacture cost and implement a high-integrated flash memory cell that is advantageous than a conventional flash memory cell in view of charge storage/retention as well as programming time.

In embodiments of the present invention, systems and methods of remotely monitoring a plurality of individuals may include providing a plurality of monitoring objects, wherein each monitoring object is associated with the environment of one of the plurality of individuals. A sensor may be integrated into each monitoring object, wherein the sensor collects activity data for the individual associated with the monitoring object. The sensor data may be processed at each monitoring object to obtain monitoring information for the activity of the individual associated with the monitoring object. The monitoring information obtained with each monitoring object may be transmitted over a network to a receiving object, wherein the receiving object may display a picture associated with the particular individual being monitored at the time that it displays information about that individual.

A shaking sensing unit includes a sensor sensing a rotation about at least one axis, a high pass filter passing only a signal having a frequency not less than a cutoff frequency of the high pass filter, among electrical signals output from the sensor, and a low pass filter passing only a signal having a frequency not greater than a cutoff frequency of the low pass filter and higher than the cutoff frequency of the high pass filter, among the electrical signals output from the sensor. The cutoff frequency of the high pass filter and the cutoff frequency of the low pass filter are variably determined according to a shaking frequency.

A battery powered, low voltage faucet flow timer, water usage calculator, and energy consumption awareness meter is simple to install and calibrate and may enable a user to understand the water usage associated with showering, bathing or other open faucet water use activity. The device may provide a simple method for calculating the flow characteristics for a shower, bath or other faucet and entering this flow rate into the timing device so that the timer provides an accurate calculation of water usage indicating both the time spent with the water running and approximate total water usage.
