摘要:
A reactance of a reactance element in a multi-layer circuit board apparatus is trimmed by cutting a portion of the circuit pattern of the reactance element with a laser beam. The reactance element is sandwiched between grounded layers. A coil circuit pattern having at least a hole therein may be provided as the reactance element. A side portion between the edge of the coil circuit pattern and the hole is cut with the laser beam to trim the inductive reactance. Cutting is effected while the circuit is operated and the operating condition such as an oscillation frequency is observed. A plurality of holes may be provided in the coil circuit pattern. The trimming amount of the inductive reactance is determined by the number of the hole subjected to cutting. The holes may have different sizes. The trimming amount is obtained by which one of the hole is subjected to cutting. The distance between the cut circuit pattern is equal to or larger than the thickness of the circuit pattern. A capacitive element may be provided as the reactance element which includes first and second comb circuit patterns of which teeth are interlace with each other. A portion of a tooth is cut to trim the capacitive reactance. Another capacitive reactance element including two conductor insulated with a dielectric substrate can be also trimmed similarly.

The present disclosure is directed to methods of preparing stable suspensions of precious metal nanoparticles and methods for attaching bio-molecules to the nanoparticles. The formation of nanoparticles can be accomplished by either chemical synthesis or pulsed laser ablation in a liquid. The present disclosure reveals the importance of controlling the conductivity of the dispersion medium during pulsed laser ablation in a liquid to control the particle size of the nanoparticles. The present disclosure also reveals the importance of adjusting and maintaining the conductivity in a range of 25 μS/cm or less during storage of the nanoparticles and just prior to performing bioconjugation reactions. The control of conductivity is an important process for maintaining the nanoparticles as a stable non-aggregated colloidal suspension in a dispersion medium.

A fuel cell is disclosed comprising: a power generation layer including an electrolyte membrane, and an anode and a cathode provided on respective surfaces of the electrolyte membrane; a fuel gas flow path layer located on a side of the anode of the power generation layer to supply a fuel gas to the anode while flowing the fuel gas along a flow direction of the fuel gas approximately orthogonal to a stacking direction in which respective layers of the fuel cell are stacked; and an oxidizing gas flow path layer located on a side of the cathode of the power generation layer to supply an oxidizing gas to the cathode while flowing the oxidizing gas along a flow direction of the oxidizing gas opposed to the flow direction of the fuel gas. A power generation area of the fuel cell, in which electric power is generated, has an upstream region including a most upstream position along the flow direction of the fuel gas and a downstream region including a most downstream position along the flow direction of the fuel gas. A midstream region, which is a remaining region of the power generation area other than the upstream region and the downstream region, has higher water vapor transfer resistance between the anode side and the cathode side than the upstream region and the downstream region.

The web load test method makes a computer function as virtual web client generation means for generating a plurality of virtual web clients each of which transmits a request message to the web server device and receives a response message according to a scenario; memory means for storing synchronous point information that specifies an order in the scenario of the response message, which should be a synchronous point among the response messages, into storage; waiting means for interrupting the accesses by the clients until the time when all the clients receive the response messages whose orders are indicated by the synchronous point information; resumption means for resuming the accesses when all the clients receive the response messages whose orders are indicated by the synchronous point information; and rewrite means for replacing the synchronous point information stored in the storage with synchronous point information that specifies another response message.

Disclosed is a scenario generation program that is used to generate a scenario given to a plurality of virtual web clients each of which applies access load to a web server device of a test target. According to the program, a computer stores some first request messages transmitted to a web server device and some second request messages transmitted to the web server device based on the same operation. The computer extracts the differences between the request parameters in the first and second request messages in the same order of the same operation. If page data of a response message includes the extracted request parameters, rewriting-item information is generated corresponding to the request parameter and is incorporated into the scenario. The computer replace the parameter shown by the rewriting-item information whenever the computer executes the scenario.
摘要:
An apparatus having a band-separating filter bank for separating a digital signal into a plurality of sub-band signals, to be processed or transmitted, and a band-combining filter bank for subsequently combining the resultant sub-band signals into a single digital signal, wherein each of the band-separating filter bank and band-combining filter bank incorporates a FIR low pass filter having an asymmetric impulse response, as the prototype filter of the filter bank. A significant reduction can thereby be achieved in the amount of overall group delay that results from the processing performed by these filter banks.
