Title: Video signal processing circuit
Inventor: USUI AKIRA
IPC: H04N11/14
Filed: 1979-06-15
Abstract: PURPOSE:To increase the video quality by perfectly rejecting chroma signal through the rejection of the chroma signal not in common with two horizontal scanning lines with the trap circuit. CONSTITUTION:The composite video signal from the input terminal 5 is divided into two, and one is through the BPF6 passing through the band of chroma signal only. The output is divided into two. One is delayed by 1H period at the delay circuit 7 and it is added with another signal not delayed at the addition circuit 8 to detect the chroma signal not in common in two scanning lines. The detection signal is obtained only for the period corresponding to the part d for difference between two scanning lines. On the other hand, the input from the terminal 5 is added with the output of the delay circuit 7 at the addition circuit 10 and the luminance signal is picked up. But, in this output, the part d chroma signal is left. Then, the remaining chroma signal is rejected for the output of the addition circuit 10 at the trap circuit 11. Thus, since the chroma signal is perfectly rejected, the video quality can be increased.

Filed: 1979-06-15
Abstract: PURPOSE:To increase the reliability of data transmission, by avoiding the discontinuity of phase at the switching point of input data, by obtaining the FSK modulation signal after the synchronism of the input data with the signals in frequencies f1, f2 and also with the FSK modulation output signal. CONSTITUTION:The input data a is formed into the signal (e) taking synchronism with the FSK modulation output signal (b) at the FF circuit 4. This signal (e) is taken with the synchronism with the signal (c) in frequency f1 at the FF circuit 5, and the signal (h) output from the gate circuit 9 starts the pulse with a delay in the maximum T1=1/f1 from the rising point of the signal (e) and the pulse is stopped at the trailing of the signal (e). On the other hand, the output signal (e) is synchronized with the signal (d) in frequency f2 at the FF circuit 6, and the signal (i) from the gate circuit 10 starts the pulse with a delay of maximum T2=1/f2 from the trailing point of the signal (e) and the pulse stops at the leading of the signal (e). FSK modulation signal (b) is obtained by passing through the signals h, i to the gate circuit 11. This signal (b) has the region in continuous with 1, 0 levels at the switching point of the input data (a).

Abstract: PURPOSE:To prevent seizure between a molten metal and a centrifugal casting mold by fixing and holding a cylindrical core material into the mold by means of suspension bolts then casting a molten metal to the outside and inside thereof. CONSTITUTION:The suspension bolts 1 are preliminarily removed. The cylindrical core material P is grasped by a bottom side ring 5 and a top side ring 6 and is contained into the casting mold 2.

Title: Communication control system
Inventor: ISAKA OSAMU
IPC: H04L47/30
Filed: 1984-04-16
Abstract: PURPOSE:To reduce data transfer time by including a flow count value of a content requesting consecutive flow of data to a response returned to an opposite station while checking the data. CONSTITUTION:When a reception side B receives a reception request from a main CPU1', the B raises a data request designating a sequence number and the flow count value, checks the received data by receiving the data in response to the response and the flow count value through packet transfer and transmits the response. The transmitted response in this case plays additionally a role of the consecutive data request message by including the last sequence number at which the data is received correctly and the flow count value being a packet number possible for reception. The reception side B receives the data to the response, checks the reception data and transmits again the response so as to complete a series of data transfer processing.

Abstract: PROBLEM TO BE SOLVED: To recover chlorine contained in combustion gas in the form of a refined calcium chloride which can be used as a regenerated resource and also is safe in handling, when incinerating shredder dust to recover a useful metal or the like as the resources. SOLUTION: When incinerating shredder dust, a generated exhaust gas is made to burn in a combustion furnace in succession to obtain a high temperature combustion exhaust gas, and this combustion gas is brought into contact with an absorbing solution consisting of a calcium carbonate emulsion circulating through a neutralization tank in a concentration column through using the thermal energy of the combustion exhaust gas, and further, a hydrogen chloride-state chlorine contained in the combustion exhaust gas is concentrated as a calcium chloride. In addition, a byproduct gypsum is separated from the obtained highly concentrated calcium chloride, utilizing the solubility difference and a contained heavy metal is removed as a sulfide by adding a sulfiding agent.  Next, an obtained highly concentrated calcium chloride solution is electrically heated to make a calcium chloride deposition with the help of a deposition condenser, and thus the calcium chloride is recovered by separation. This method and device for recovering the chlorine from shredder dust are characteristic of the described recovery process.
