Title: Composite cord for reinforcing rubber article
Inventor: OKAMOTO KENICHI
IPC: B60C9/00
Filed: 1992-06-04
Abstract: PURPOSE:To provide a composite cord free from the problem of low cut resistance of organic fiber cord as a drawback thereof while making the best use of its advantages, also suppressed in cord diameter increment to the utmost. CONSTITUTION:Plural metallic filaments 2 are spirally wound around an organic fiber cord 1 and, thereon, plural metallic filaments 3 are wound in the direction opposite to that for the metallic filaments 2. Because of being high in the ratios of the real lengths of the filaments 2, 3 to the cord length for the filaments 2, 3, the extensibility of the organic fiber cord 1 is virtually invariable, and because of being plural in both two kinds of the metallic filaments, cord diameter does not increase so much and since the extent of coverage of the cord 1 with these metallic filaments is high, it improves the cut resistance of the cord.

Abstract: PURPOSE:To attain the control preferable to a video device, by performing the generation of a control signal controlling the reception of printing data from a computer device with the detection of the video signal of the video device. CONSTITUTION:When a video detecting command is transmitted, a timer 26b is triggered, and an ROM IC21a is made active with the triggering. Then, an output D7 of the IC21a goes to H and an NAND gate 26m goes to L.

Then, even if the timer 26b is restored, the IC21a remains active. When the video signal is inputted and the output of the circuit 27 goes to H, the output of the gate 26i goes to L and the output of an NOR gate 26j goes to H. Then, the IC21a is made inoperative. Further, the output of an inverter 26e goes to H, a control signal ACK terminal goes to L for a prescribed time and the end of execution of the command is informed.
