    摘要: Two-wire television interphone system is arranged to discriminate by a line voltage discriminator incorporated in a master device a line voltage variation due to a calling operation on the side of a branch device, to actuate a voltage controller in the branch device to shift the system from standby state to operation state, and to drive a call signal generator in the branch device for actuation of a call signal receiver in the master device. The system is thus made to have a power supply circuit energized for a power supply to the system only when required for effecting the calling operation, talking between the both devices, and so on.

    摘要: A balanced-to-unbalanced transformer for interconnecting a balanced signal transmitted on a balanced cable and an unbalanced signal transmitted on an unbalanced cable through a transformer. Common-mode impedance is reduced by grounding a center point of two or more impedance elements between signal lines on the balanced cable side of the transformer to a signal circuit ground or a frame ground on the unbalanced cable side of the transformer.

    摘要: The invention relates to a printing method by an offset printing press and an offset printing press by which a substrate process is carried out for low-whiteness printing paper such as paper for newspaper with aqueous substrate treatment agent so that the print quality can be improved. In the invention, in order to suppress occurrence of a curl of printing paper, substrate treatment agent containing solid fine particles and a binder component is supplied to a printing face of printing paper, and the substrate treatment agent is dried to form a porous layer having a great number of holes having a smaller diameter than that of pigment contained in printing ink from the solid fine particles and the binder resin. Then, offset printing is carried out on the printing paper.
