Abstract:
A ceramic compact having a patterned conductor is obtained by coating the patterned conductor with a slurry and then by hardening the slurry. The slurry is prepared by mixing a thermosetting resin precursor, a ceramic powder, and a medium. In the ceramic compact, an isocyanate- or isothiocyanate-containing gelling agent and a hydroxyl-containing polymer are reacted and hardened to produce a thermosetting resin. The hydroxyl-containing polymer is preferably a butyral resin, an ethylcellulose-based resin, a polyethyleneglycol-based resin, or a polyether-based resin.
Abstract:
A communication system that can improve communication quality by accurately re-creating reproduction timing at the receiving end even at the time of receiving VBR data or in the case of the occurrence of a packet loss. A send rate recognition section recognizes a send rate from a time stamp. A memory stores data. A dummy data addition section adds dummy data for correcting the difference between a read rate set for reading out data from the memory and the send rate to the data written to the memory. A read clock generation section generates a read clock which is equal to the read rate. A dummy data removal section removes the dummy data from the data read out from the memory on the basis of the read clock.
Abstract:
A receiving large scale integrated circuit (LSI) device, including a demodulator which includes two signal processing circuits to demodulate two diversity signals to form a demodulated signal, a decoder which decodes the demodulated signal in accordance with an error correcting code to form a decoded signal, a receiving quality judgment circuit which codes the decoded signal to form a re-coded signal as a reference signal, compares the demodulated signal with the reference signal to obtain an error rate of the two diversity signals and supplies a judgment signal depending on the error rate, and a control circuit which selects one of the two signal processing circuits or both two signal processing circuits in response to the judgment signal of the receiving quality judgment circuit and stops supplying electric power or a clock signal to the one of the two processing circuits not selected by the control circuit.

Abstract:
An abrasive material is prepared by dispersing silicon nitride particles acting as abrasive particles in a solvent such as a pure water or an ultra pure water, followed by adding an adsorptive stickable to the abrasive particles to the dispersion. The resultant abrasive material permits diminishing the polishing rate of a silicon nitride film used as a stopper film, with the result that a CVD SiO.sub.2 film to be polished is selectively polished relative to the Si.sub.3 N.sub.4 film used as the stopper film. This makes it possible to make the stopper film as thin as possible and permits the CVD SiO.sub.2 film to be flattened efficiently without bringing about a dishing problem.
Abstract:
An electrolytic ionic water generating apparatus that produces electrolytic ionic water having a desired pH value and a semiconductor manufacturing apparatus that uses the electrolytic ionic water. The invention includes an electrolytic tank with an anode chamber and a cathode chamber, an introducing conduit or line to introduce electrolytic solution, and a discharge conduit or line to supply the generated electrolytic ionic water to other apparatuses such as a semiconductor washing machine and a semiconductor polishing machine. To control the pH value of the electrolyzed ionic water, pH meters and pH controllers are disposed on the introducing or discharge conduit. The pH meters detect the pH values of the electrolyzed ionic water and provide the detected result to the pH controllers. The pH controllers control the pH values of the supplied ionic water by controlling and changing the temperature of the solution.
