Title: Very high speed frequency-dividing circuit
Inventor: MURAGUCHI MASAHIRO
IPC: H01P5/18
Filed: 1988-02-05
Abstract: PURPOSE:To obtain a double phase clock generating circuit not to have a band characteristic by making the output impedance of a double phase output terminal into Z0/2 to the input impedance Z0 of a single phase input terminal in the double phase clock generating circuit of 180 deg. phase difference. CONSTITUTION:A single phase clock signal inputting from an input terminal 1 is equally distributed into two clock signals different in phases at 180 deg. in non-reflection, propagated in slot lines 2 and 3, and non-reflection-absorbed by a terminating resistance 4. High impedance input connecting lines 5 and 6 are pulled out from a conductor not to be shared between the lines 2 and 3 and connected to the clock signal input terminal of a frequency-dividing circuit part. Further, the conductor to be shared between the lines 2 and 3 is connected to the grounding terminal of the frequency-dividing circuit part by a low impedance line 7. The voltage of the clock signals propagated in the lines 2 and 3 are impressed to two input terminals of the frequency-dividing part. Since the voltages of the clock signals propagated by the connecting lines 5 and 6 are different by the phase difference 180 deg., the frequency-dividing circuit part of the double clock input can be driven.

Title: Delta-sigma ad converter and receiver
Inventor: OOTA SHIGENORI
IPC: H03H17/02
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a decimation bandpass filter which outputs signals having high bit accuracy to an AGC circuit and has a simple constitution, without increasing the hardware scale and electric current of the filter by decimating the output of a bandpass ΔΣAD converter which has an AGC function and enabling the converter to make accurate AGC control. SOLUTION: A bandpass ΔΣAD converter 1 converts inputted IF signals into digital signals. A decimation bandpass filter 2 decimates the output of the AD converter 1 so that a 1:4 relation is established between the frequency of the inputted signals and a sampling frequency by means of the input section of an orthogonal detector 4. A bandpass filter 8 outputs the output signal of the decimation bandpass filter 2 to an AGC circuit 3 by limiting the band of the signals. Since the bandpass filter 8 can be constituted without the use of multipliers, etc., the filter 8 can be realized with a simple constitution without increasing the hardware scale and electric current of the filter 8.

Title: Continuous casting and continuous hot rolling method of steel slab
Inventor: AKISUE OSAMU
IPC: B21B1/46
Filed: 1982-02-22
Abstract: PURPOSE:To eliminate the conventional long-time heating at a high temperature and to save the energy to realize the economical production of steel, by combining a continuous casting stage and a continuous hot rolling stage. CONSTITUTION:A heat insulator is put over the surface of a high-temperature steel slab which has just been cast, and accordingly, the temperature of the slab is unified in the width direction of the slab plate by heat recuperation of the slab itself. Then the steel slab is hot-rolled. Thus a high-temperature slab after receiving the continuous casting is directly hot-rolled to produce a hot-rolled steel band or a cold-rolled steel plate. In such a way, a great deal of energy which is hitherto required for reheating is saved to more enhance the material characteristics than that secured by conventional stages.
