摘要： A package assembly and method of loading and unloading said package assembly is disclosed. The package assembly of the present invention includes moving parts to make the loading and unloading steps of a relatively delicate instrument of substantial weight easier and safe. The basic package assembly includes four component parts: an outer carton 10, an inner carton 12, a blocking panel 14, and top tray 16. In several of the embodiments, the top tray 16 is combined as a single unit with either the blocking panel 14 or the inner carton 12, thus reducing the parts count to three. In the unloading of the instrument, blocking panel 14 and tray 16 are first removed, outer carton 10 is rotated about one of its lower edges 30 to bring side 31 to rest on the floor. During the rotation of outer carton 10, inner carton 12 slides within outer carton 10 to bring the bottom of the enclosed instrument to rest on its bottom surface within the outer carton 10 allowing its easy removal by sliding it from the packaging.

摘要： An analog switching circuit may be implemented with MESFETs without forward biasing the switching device, and is applicable to JFET switches in general. Switching currents are provided from the nominal input line which closely tracks the true analog input voltage, but is segregated therefrom. A current supply fed from the nominal input line provides transient charging current to the gate of the switching transistor during the switching transition from OFF to ON states. Voltage setting devices hold the gate and source of the enhancement-mode current supply at approximately the nominal supply voltage level when the switching transistor is ON, while a control section holds the gate and source of the current supply device at a negative reference voltage level when the switching transistor is OFF. In either case, the current supply device is inhibited from delivering gate current to the switching transistor during steady state operation.
