Title: Radio communication system
Inventor: IIZUKA SHOGO
IPC: H04K1/00
Filed: 1987-09-16
Abstract: PURPOSE:To prevent a pyrate terminal station from intercepting the content of communication by a terminal station and a command station by sending a cryptographic code erasure signal to a terminal station being poached for every transmission by the command station while adopting a 2-frequency simplex system. CONSTITUTION:A cryptographic code data erasure signal is sent from the com mand station to the terminal station being poached prior to the communication by the 2-frequency simple communication system and if the terminal station being poached tries to intercept a data, the cryptographic code of the terminal station being poached is erased. Thus, even when the terminal station is poached, the interception is prevented in advance. Moreover, in designing a high reception rate of the cryptographic code data erasure signal, the erasure of the cryptographic code at a weak electric field fails and the possibility of decoding only voice is precluded.

Title: Automatic white balance adjusting circuit for color television camera
Inventor: TAKIZAWA YOSHINORI
IPC: H04N9/07
Filed: 1987-09-14
Abstract: PURPOSE:To obtain stable white balance without generating slipping off of color with respect to all light sources by adding a negative feedback loop by R-Y or B-Y signal. CONSTITUTION:The feedback loop of an inversion amplifier 21 controls the variable quantity of a Y signal. The R-Y signal 113 increases when color temperature drops, and decreases when the temperature rises, since a change in R components in a luminance signal is smaller than the real change in separated R signal. Consequently, the outputs of the inversion amplifier 21 decreases with respect to the drop of the color temperature, and increase with respect to the rise of the color temperature. The control signals are added to the control signals of the other, namely, of the R-B feedback loop through a resistance 22. If the amplifier gain of the inversion amplifier 21 is taken considerably large, the convergent point of feedback by the R-Y signal goes to R=Y. Thus, the completely white-balanced state of Y=R=B can be realized in combining with the convergent point R=B of feedback.

Abstract: PURPOSE:To enable analysis of a dilute sample by changing over heating control and the flow of a carrier gas for a sample evaporating chamber, removing the solvent occupying the greater part in a sample solvent and introducing only the intended component into a capillary column. CONSTITUTION:A sample soln. is dropped through a septum 5 onto silica wool 6 in a sample evaporating chamber. The temp. in this state is set at about the temp. at which only the solvent in the sample soln. can evaporate. Stop valves 1, 3 are closed and a stop valve 2 is opened so that the carrier gas passes through a pressure regulator 8 and the valve 2 then through the inside of an inside cylinder 7 and is released to the outside through the valve 1. The solvent having high volatility in the sample soln. is therefore evaporated and is discharged through a discharging part 22 to the outside of the system. The valves 1, 2 are then closed and the valve 3 is opened to reverse the flow direction of the carrier gas in the cylinder 7; at the same time, a heater 8 is energized to heat quickly the sample evaporating chamber 18 and to evaporate the intended component remaining in the wool 6. The component is fed into a capillary column 6 and is detected suitably with a detector 10.
