Abstract

PURPOSE:To remove a malfunction due to the mixing of noises and the strain of a digital signal by forming a photoelectric conversion element corresponding to input/output pins for a logic IC into an IC socket. CONSTITUTION:A photoelectric conversion element 70 corresponding to an input/output pin 20 for a logic IC 10 is shaped into an IC socket 30. A digital electric signal from the IC 10 is transmitted over the element 70 from the pin 20, converted into the pulse signal of beams corresponding to the digital electric signal and sent to an optical fiber 60. On an input signal, the pulse signal of beams being transmitted from the fiber 60 is converted into a digital electric signal by the element 70, and sent into the IC 10 through the pin 20. Accordingly, a malfunction due to the mixing of noises and the strain of the digital signal is removed.

When installing digital equipment in a factory site with large-capacity motors or high-frequency sources, large switching noise may enter the digital equipment from the power supply line or ground line, causing the equipment to operate abnormally or run out of control. Therefore, sufficient noise countermeasure technology has been required.

Examples of noise that enters digital equipment and causes abnormal operation include noise that enters from the power line, ground line, and strong high frequencies. The first point is that it is dependent on the external environment, such as J'-electromagnetic waves that jump into wiring wires, become noise, and are superimposed on digital signals.

The second point is that due to the interference component of the wiring wire itself, when the wiring is long, the wiring itself may generate h'-noise.
In case of t, it will cause &, and the digital signal will be distorted.
There are some things that depend on shortcuts in business, such as ÷.
As noise countermeasures for points 1 or 2, the timing of the digital signal may be intentionally delayed, inserting a capacitor, rewiring the IC, installing a new shield plate or shield case, using a noise cut transformer, using a shield cable, etc. , various noise countermeasure techniques are required. Furthermore, because countermeasures against trapping noise have been taken at the same time, there have been problems such as the inability to increase the operating speed of the circuit and the need for different countermeasures against noise depending on the installation location of the digital equipment. The causes of these problems are that the power lines and ground lines of ICs in digital devices are electrically connected to each other, and that wires are used for wiring, so noise can be mixed in and generated in the wiring wires. The cause is most likely in an easy place.
