Inventor: SUNGO JIN
IPC: C01G3/00
Filed: 1990-11-22
Abstract: PURPOSE: To obtain a high-temperature superconductor material of increased intra-grain critical current density by composing a nominal composition of a composition of desired superconductive oxides and substances having at most different oxygen content as a polyphase and forming polyphase substance of a dispersed sedimentation phase in the whole or a major portion of the polyphase.  
     CONSTITUTION: The superconductor substance having a nominal composition M x M ' y ...O 2 , e.g. of the nominal chemical formula; (RE)Ba 2 Cu 3 O 2  is manufactured by the method mentioned below. Namely, the superconductive precursor oxides and precursor substance of different chemical composition are thermally treated in an O 2 -containing atmosphere and the superconductive oxides are manufactured by the method mentioned below. Namely, at least a 1st metal element is present in the precursor substance with mean composition stoichiometrically different from that of the superconductive oxides. Then the polyphase substance formed by the thermal treatment has a 1st phase difference from the superconductive oxides as to at most oxygen. The polyphase substance consisting of a sedimentation phase is the 1st metal element and dispersed in a major portion of the 1st phase. Consequently, the superconductive oxides having a relatively high Jc' value are obtained.

Title: Communication equipment
Inventor: MATSUGAKI ISAO
IPC: H04L27/18
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To realize a digital modulator to be used for a communication system by simple circuit constitution or soft processing by controlling a sampling frequency by the center frequency of the desired channel of a received signal to convert the center frequency of the signal after sampling to a specific frequency which exists at the time of setting the sampling frequency to be a reference. SOLUTION: An A/D converter 21 converts an analog reception signal 19 into a digital reception signal 22 according to the timing of a reception sampling pulse oscillator 20. The oscillator 20 is controlled by a received frequency control signal 18 so that the center frequency of the signal 22 becomes 1/4 of a sampling frequency. In this case, processing for converting the frequency to a same phase and an orthogonal phase is executed by simple processing being alternate separation and code inversion of every other sample to unnecessitate a multiplier and also, the oscillator generating the sampling frequency is not required to generate a sine wave to remarkably reduce a circuit scale.

The open cross section is reduced when the tank exhaust air-fuel mixture becomes rich beyond the desired quantity, and is enlarged when the tank exhaust air-fuel mixture does not become rich by the desired quantity. The tank venting valve is driven at a predetermined duty ratio derived from a data generator 16 and is regulated in accordance with a characteristic curve 24 relating to the average value of a Lambda correction factor FR.  When enrichment due to the tank exhaust air-fuel mixture occurs, the duty ratio is decreased correspondingly to close the tank venting valve.
