Title: Transmission system, transmitter and receiver for picture signal
Inventor: WAKABAYASHI SHIGEHIRO
IPC: H04N1/36
Filed: 1988-12-29
Abstract: PURPOSE:To use only two signal transmission lines and to eliminate the need for troublesome timing adjustment at the receiver by sending a picture signal and a synthesis signal between a phase signal and a clock signal to separate transmission lines whose signal transmission characteristic and length are substantially identical to each other respectively. CONSTITUTION:A transmitter 1 forms a synthesis signal between a phase signal PHS and a clock signal CLK and sends the synthesis signal and a picture signal DATA to separate transmission lines 3, 4 or 5, 6 whose signal transmission characteristic and length are substantially identical to each other respectively, and a receiver 2 demultiplexes the phase signal and the clock signal for synchronizing the picture signal received from one transmission line 3 from the synthesis signal received from the other transmission line 4. Thus, the phase signal and the clock signal are sent through one transmission line as the synthesis signal and demultiplexed at the receiver side, then there is no fluctuation in the mutual timing. Since the signal transmission characteristic and the length of the said transmission line and the transmission line for the picture signal are substantially identical, there is no fluctuation in the timing between the picture signal and the synthesis signal between the phase signal and the clock signal. Thus, no timing adjustment between the signals in the receiver is required.

Abstract: PROBLEM TO BE SOLVED: To obtain a member for the electrochemical control of organisms or for preventing fouling in which deterioration is prevented to the utmost and high in durability by applying any conductive coating of metallic nitride, metallic carbide, metallic boride and metallic silicide to the face to be contacted with water. SOLUTION: This member for the control of organisms or for preventing fouling is the one in which conductive coating 2 composed of any of metallic nitride, metallic carbide, metallic boride and metallic silicide is formed on a substrate 1. In the case a positive potential is applied to the conductive coating 2, the organisms in water is adsorbed to the surface of the conductive coating and are sterilized on the surface. Even if the potential is applied to the conductive coating 2, these metallic compounds are high in corrosion resistance, are free from dissolution and oxidation and are very stable, so that the control of organisms and the prevention of fouling can be executed over a long period, and the fouling of products such as foods, drinking water, pharmaceuticals or the like does not occur. Furthermore, since these metallic compounds are high in electric conductivity and small in the reduction of the potential in accordance with the resistance value of the conductive coating, fouling caused by organisms can be prevented in a wide area. Moreover, since its surface hardness is high, wear and peeling in a distributing pipe are not generated.
