Title: Ftc circuit
Inventor: HITAI TAKASHI
IPC: G01S7/292
Filed: 1988-02-19
Abstract: PURPOSE:To suppress the reflected signal component from wind and snow without suppressing the echo signal from a target too much, by applying peak charge to a variable time constant circuit corresponding to an input video signal by a non-linear element and detecting the charge current waveform generated at this time. CONSTITUTION:An input video signal S1 containing an unnecessary signal component consisting of a DC part reflected from wind and snow to change gently and a high frequency component having an almost uniform level is inputted to an input terminal 10 and a non-linear element 11-2 applies peak charge to a variable time constant circuit 12 corresponding to said signal. This charge current waveform is detected by a current detection circuit 11-1. Herein, in the high frequency component having the almost uniform level, only a gentle charge current is permitted to pass and the charge current of the DC component changing gently becomes slight of course but a large charge current flows in a high level signal component relating to a target. Therefore, when this charge current is detected by the circuit 12, a signal suppressed in both high frequency and DC components can be obtained.

Filed: 1981-03-13
Abstract: PURPOSE:To simplify the equipment by placing a rolled texture on texture releasing rolls as well as by rotating a rotary bed, which supports the rolls, on a travelling truck. CONSTITUTION:A texture releasing conveyor is constituted such that a rolled texture 73 is placed on a pair of releasing rolls 9 and 10, which are arranged in parallel, while a rotary bed 7, which supports the releasing rolls 9 and 10, is rotated on a travelling truck 1. With these contrivances, the structure of the equipment can be simplified in comparison with the conventional one, while the shaft centre line of the rolled texture 73 and those of the releasing rolls 9 and 10 are always kept in parallel because the texture 73 is released under the restriction of the releasing rolls 9 and 10, thus the irregular releasing may be prevented in order to obtain the smooth texture releasing.

IPC: H03K19/23
Filed: 1988-02-19
Abstract: PURPOSE:To improve the reliability of a whole system by obtaining the average value of plural input signals to execute majority, comparing the value with a threshold to be set in advance and deciding the establishment of the majority. CONSTITUTION:The input signal is connected through resistance element 4-6 to one point 7 and the average potential of the input signal is generated in this connecting point 7. When this potential and the threshold are compared by a comparing circuit 9, the majority result of the input signal appears in an output terminal 10. Thus, since the degree of the increase for the coupling of the input signal is smooth to the increase of a multiplexing degree, a multiplexing degree N of the system can be increased without generating the lowering of the reliability of a majority circuit. Thus, the reliability of the whole system can be improved.

Abstract: PURPOSE: To remove the excess moisture stuck to a coil and a furnace refractory, to prevent the development of an oxide layer on the width edge parts of coiled strip at the time of executing finish-annealing and to improve the surface quality of the bright steel strip and the product yield. CONSTITUTION: At the time of annealing the tight coil, an annealing is executed at the temp. of 450-580 deg.C which is lower than a prescribed annealing temp. in the initial stage and successively the finish-annealing is executed.
