  • Publication number: 20160325224
    Abstract: A compressed air drying device includes a support base including an inlet of compressed air from a compressor, an outlet of the compressed air, and a discharge port of oil and water. The discharge port includes a drain valve device and a drying container. The container is filled with desiccant and is installed in the support base. In a loading operation, the compressed air drying device causes the desiccant to dry the compressed air introduced through the inlet and discharges the dried compressed air through the outlet. In an unloading operation, the compressed air drying device causes the compressed air to pass through the container to discharge oil and water from the discharge port. A glass fiber filter is provided at one or more of a position upstream of the desiccant and a position downstream of the desiccant in a flow of the compressed air during the loading operation.

  • Patent number: 9331781
    Abstract: A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Use of transparent glass ferrule with or without a front surface anti-reflection coating instead of an opaque ceramic ferrule to support optical fiber at a selected location within the transreceiver reduces optical detector signal noise. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication.
