Title: Frequency tracking circuit
Inventor: TOMINAGA KIYONORI
IPC: H03L7/08
Filed: 1978-12-21
Abstract: PURPOSE:To prevent the external disturbance of loop due to high to low band interference signal and noise, by using the two tracking filters parallelly and making different the group delay time at the center frequency of each filter. CONSTITUTION:To the input signal varying in the frequency, the first and second tracking filters 42, 45 are coupled parallelly.

Abstract: PROBLEM TO BE SOLVED: To prevent toner from sticking to a transfer-material carrier even when pattern images for the detection of an amount of toner, the number of which corresponds with the size of a transfer material to be subjected to image formation, are formed on a specific part of a photoreceptor. SOLUTION: A pattern image 6 for the detection of an amount of sticking toner, obtained by developing a specific pattern latent-image with toner for image-density adjustment is formed on the photoreceptor 3, in an area where a toner image is not formed yet which does not coincide with a transfer material. On the other hand, a non-transfer area which comes opposite the pattern image 60, used for the detection of the amount of sticking toner, in a transfer position on the transfer-material carrier is pre-electrified to the same polarity as that of the toner by electrifying means 26 and 27 before reaching the transfer position, thereby causing the toner 60a of the pattern image 60 for the detection of the amount of sticking toner to repel electrically the non-transfer area opposite it.

IPC: H04Q11/04
Filed: 1981-10-05
Abstract: PURPOSE:To make a special monitor trunk and an exchange terminal for storing it unnecessary to simplify the constitution, by leading in all channels of a digital multiple line and by-passing them to designate an optional channel. CONSTITUTION:In case that the digital signal on an optional channel of a digital multiple line 5 is monitored, a central controller instructs an interface 4, which is connected to the digital multiple line 5 (a corresponding outgoing line 3) including the channel to be monitored, to split the digital multiple line 5 and the outgoing line 3. On a basis of this instruction, the designated interface device 4 splits the digital multiple line 5 and the outgoing line 3 simultaneously and leads channels into an interface device test module 9 by a leading-in line 8. The interface device test module 9 by-passes all led-in channels by the instruction of the central controller and mixes digital signals in the transmission side and the reception side of the disignated channel, and these signals are converted to analog signals and are outputted.

Abstract: PURPOSE:To automatically switch a line to a backup line and to inversely reswitch it by discriminating the content of carrier disconnection by means of a case when data transmission terminates owing to the turning-off of a transmission requiring signal and a case when a line is disconnected owing to the fault of the line. CONSTITUTION:A first switching means 11 transmitting a signal from a pattern insertion means inserting a prescribed pattern into a signal transmitted to a reception-side to an active line 3 or the backup line 4 is provided on a transmission-side 10, and a second switching means 21, 22 and 24 selecting the signal from the active line 3 or the backup line 4 for the reception-side 20. Usually, the first and second switching means 11, 21, 22 and 24 are controlled and the active line 3 is selected. When a carrier is disconnected, the first and second switch means 11, 21, 22 and 24 are controlled and the backup line 4 is selected when the prescribed pattern is not detected in the signal from the active line 3. Thus, carrier-off is distinguished and the line can automatically be switched.

Meanwhile, signals from the VSB filter 102 and a phase shifter 104 are mixed by a mixer 105 to output the signal of the component having the phase orthogonal to the input VSB-AM wave. The Y signal low-band converted high-band signal (YH') is taken out by a low-pass filter 108 and is digitized by an A/D converter 110 and is restored to the original signal level by a level adjuster 111. Frequency deinterleave of this signal is performed by a deinterleaving circuit, which consists of a 1H delay line 115 and an adder 116 and has a delay time corresponding to one horizontal period, to obtain a signal YH.

Abstract: PROBLEM TO BE SOLVED: To recycle slurry from mud discharged to the ground surface and increase the construction efficiency of underground piles and reduce the treat ment cost for discharged mud and decrease further the industrial waste. SOLUTION: Peripheral ground is cut by slurry W continuously jetting from a jet structure 7 and the spiral jet flow of air A. The cut mud is agitated and kneaded in parallel to the cutting work by a curing material G continuously jetting out of the jet structure 7 to construct an underground pile P in the cut area 11a thereof. In this time, the curing material G is separated from the mud H by the difference between these specific gravities. And the upper stage jet nozzles 7a, 7b and the lower stage jet nozzles of the jet structure 7 are arranged with a distance to prevent mixture of the curing material G and the mud H and separate the slurry W from the mud H discharged to the ground level and regenerate it and reuse it circularly.  Most of larger grains of sand and gravel included in the cut mud H settle down and these are agitated and mixed with the curing material G and reused for construction of the underground pile P and hence, gravels and mud slurry discharged to the ground surface are reduced.
