A resistor bypass circuit for a series lighting circuit includes a plurality of serially connected light sources and a bypass resistor being connected in parallel with at least one of the respective light sources, each respective light source being low wattage and being capable operating on a one hundred percent duty cycle as desired.

A mini light machine system for evenly distributing a light strand along a window frame and adhering the light strand to a window with easy peel tape. The mini light machine system has a mini light machine assembly. The mini light machine assembly has a placing machine for placing and adhering a light strand and a light box container for condensed loading and storage of a light strand. In the preferred embodiment the mini light machine assembly is self-propelled and automatically places a light strand in repeatable distances between the individual lights. The mini light machine assembly adheres to a vertical window surface allowing lights to be placed in hard to reach places. Intelligent control is used to cease operation when the mini light machine assembly reaches the end of a window frame. The mini light machine assembly contains a battery thus eliminating the need for power chords.

An alumina ceramic member contains an alumina polycrystal with an average grain size less than or equal to 100 m. The alumina ceramic member is doped with yttrium in a state other than a crystalline state of an oxide, a crystalline state of a garnet structure, or an amorphous state, at grain boundaries of the alumina polycrystal.

An apparatus for manufacturing a spark plug by working of a workpiece with dies, wherein the workpiece has a metal shell part to be processed into a metal shell of the spark plug and a ground electrode part to be processed into a ground electrode of the spark plug. In the manufacturing apparatus, a position of the ground electrode part is measured in a non-contact manner by a position measurement unit in a state where the workpiece is held in position by a holding unit. The dies are controlled by a die control unit so as to adjust the working phase of the dies relative to the workpiece based on the measured position of the ground electrode part and then effect working of the workpiece with the dies.
