摘要： A connector assembly for coupling a corrosive gas supply pipe with a glass tube in an apparatus for fabricating an optical fiber preform using vapor deposition is disclosed. The connector assembly includes a first connector formed on an inner periphery thereof with a threaded portion, a second connector having a stepped surface on an inner surface and formed on an outer periphery with a threaded portion threadedly engaged with the first connector, an O-ring installed in the first connector and in close contact with the stepped surface when the second connector is threadedly engaged with the first connector, and resilient means for urging the O-ring against the stepped surface. The connector assembly consistently applies a resilient force to the O-ring functioning as a seal between the first and second connectors. For a long-running operation, even though the O-ring is cured, the fitting maintains a consistent sealing state to prevent metal material from being oxidized by the corrosive gas. As a result, fine oxidized metal particulars do not infiltrate into the gas supply pipe to prevent the optical fiber preform from deteriorating.

摘要： A temperature compensation device for an optical communication device or the like is constructed so that an error value, which is the difference between the current temperature and a reference temperature, is subjected to digital processing in a temperature comparison unit. A digital error voltage value is calculated and digital PID control is performed instead of analog PID which requires electric components such as a power op-amp, a resistor (R), and a capacitor (C). According to this construction it is possible to reduce the number of electric parts. It is also possible to accept various types of temperature sensors while using only one PCB regardless of the types of temperature sensors utilized.
