摘要： A circuit adapted to receive at its input terminal signals having either a first or a second value includes a level shifting transistor for shifting the second value signals at its input terminal to a third value, where the second value is intermediate the first and third values. The transistor is turned on and off as a function of the voltage at a first node at which is produced the inverse of the input signals. An output terminal is coupled to the first node for one value of input signal and is decoupled from it for the other value of input signal. Decoupling enables the level shift transistor to always be operated as a function of the input signal while enabling signals incompatible with the signal at the first node, produced by other circuitry, to be present at, or applied to, the output terminal.

摘要： A revolving coin display stand for the display of proof coin sets encased in hermetically sealed plastic display cartridges is disclosed. The coin display stand is constructed so as to permit a user to view both the obverse and reverse sides of the coins by manually revolving a pivoting frame assembly 360 degrees relative to a supporting base plate. The base plate is constructed of sufficient weight to prevent the proof coin set which is permanently captured in the supporting frame from toppling over during rotation by a user. In an alternative embodiment the supporting base is provided with writing implement holders adapted to receive implements such as pens and pencils in the maimer of a traditional desk set.
