The invention provides a method and device for administering an amine drug, such as S–2-4-piperazin-1-ylcarbonylphenoxy-3,3-diethyl-N-1-butyl-4-oxo-1-azetidinecarboxamide), in a sustained release dosage form. The present invention also relates to a process for the preparation of novel substituted 1,4-dioxa-8-azaspiro4,5decanes of general formula. The capacitors use different metallization patterns to form the metal layers, and different via patterns to couple adjacent metal layers. A ratio of a static beam-spot diameter Ws in the sub-scan direction on the surface of the photosensitive body defined by 1e2 of the maximum value in the exposure distribution of the beam spot to an interval L between adjacent scan lines satisfies the following formula: 1. An accelerometer in the headset continuously tracks user movement. A bi-directional switch is operable to interrupt or limit current flow though the power supply circuit responsive to the change in the state of the overvoltage output.
