Isolation trenches and capacitor trenches containing vertical FETs having an aspect ratio up to 60 are filled with a process comprising: applying a spin-on material based on silazane and having a low molecular weight; pre-baking the applied material in an oxygen ambient at a temperature below about 450 deg C. Each planar thermal zone uses at least one Peltier device as a thermoelectric element. The magnetization of the spins then precesses around earth’s magnetic field at a Larmor frequency corresponding to the earth’s field. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter. Additional indicia on the device is associated with a practice putting game, and a method of playing the practice putting game also is disclosed. A hollow space is formed in a portion of the rotation center of a reduction gear, a motor mounting member for maintaining a distance between the center of rotation and a rotating shaft of the motor to a fixed distance, and a front-stage reducing portion for reducing the output rotation of the motor is provided between the center of rotation and the rotating shaft of the motor.
