摘要:
Disclosed is a port for a vertical wall, a multi-filter used therein, and a port support frame. In the port a cover is installed in a port body having an interior space. A plurality of body filter holes penetrate the port body. Soil in which plants are set is filled in the interior space. A plurality of vegetation holes through which the plants set in the soil are formed in the cover, and cover filter holes are formed between the vegetation holes at locations corresponding to the body filter holes. Multi-filters penetrate the body filter holes, the cover filter holes, and the soil. A support tubular body forms an outer appearance of the multi-filter, and a filtering case is installed in the support tubular body.

A meter for measuring the root-mean-squared potential of an AC signal characterized by a frequency f is disclosed. The meter includes first and second capacitors. The AC signal is applied to the first capacitor, which includes first and second plates separated by a distance that depends on the root-mean-squared potential of the AC signal, but not on changes in the AC signal that occur over a time of 1/f. The second capacitor has first and second plates separated by a distance that depends on the separation of the first and second plates in the first capacitor. A detection circuit measures the capacitance of the second capacitor. The first plate of the first capacitor is preferably connected to the first plate of the second capacitor by a non-conducting mechanical link.
摘要:
An integrated circuit (IC) with high electron mobility transistors, such as enhancement mode pseudomorphic high electron mobility transistors (E-pHEMTs) and method for fabricating the IC utilizes an increased gate-to-drain etch recess spacing in some of the high electron mobility transistors to provide on-chip electrostatic discharge protection. The use of the increased gate-to-drain etch recess spacing allows smaller high electron mobility transistors to be used for ancillary low speed applications on the IC, which reduces the chip area occupied by these ancillary transistors.
摘要:
A passive interface circuit for coupling an output signal from a power amplifier to a load is disclosed. The interface presents an impedance to the power amplifier that increases as the power level in the output signal decreases. In one embodiment, the interface circuit includes a fixed network and a capacitor having a capacitance that varies with the potential across the capacitor. The fixed network couples the output signal to the load. The capacitor is connected in parallel with the load and has a capacitance that increases in response to an increase in potential across the capacitor. The capacitor is preferably a MEM capacitor having plates that move with respect to one another in response to changes in the average potential difference between the plates.

A system and method for searching for musical pieces utilizes a hardware-based music search engine that includes a systolic array of comparison circuits to correlate musical query data for a desired musical piece with at least some of musical information data from a music database to determine potential musical pieces that are candidates for the desired musical piece.
摘要:
A method for forming a temperature-compensated resistor on a semiconductor substrate is provided. A resistor element is formed on the semiconductor substrate. Terminal contacts are formed on the ends of the resistor element. A temperature-compensating configuration is formed, and is selected from an enlarged transverse portion in the resistor element intermediate and spaced from the terminal contacts, and at least one contact pattern along and in contact with the resistor element intermediate and spaced from the terminal contacts.

Multi-chip memory devices include at least two integrated circuit memory chips, each of which includes corresponding address pads, data pads and control signal pads, and a common package that encapsulates the at least two integrated circuit memory chips, and that includes external terminals. An internal connection circuit in the common package is configured to connect at least one of the corresponding control signal pads of each of the integrated circuit memory chips to separate ones of the external terminals, to allow independent external control of each of the integrated circuit memory chips that are encapsulated in the common package. Multi-chip memory devices may be combined to form memory modules. The memory modules include a memory module substrate having first and second opposing surfaces. At least one multi-chip memory device, as described above, is provided on the first surface and on the second surface.
摘要:
An amplifier system is provided for amplifying an input signal to provide an amplified output signal, amplifying an amplified input signal to provide a further amplified output signal, and phase delay compensating variations of the amplifications of the amplified output signal and the further amplified output signal for providing the further amplified output signal with substantially linear amplification under a variable load.
