Balancer

This morning NHK News program broadcasted about the rear-end collision traffic accident on Meishin Highway around Nagahama, probably it must be caused by falling asleep at the wheel leading to fatal. I must declare here that "Zero Thrust" adjusted vehicle has some tendency to fall asleep apparently compared with ordinary ones. The reason is that less concentration is required while straight running, so too much relaxed condition causes drowsiness. Anyway, Thrust adjustment has both merits and demerits.

Old balance scales has found in my junk box probably a production of half a century ago. We do not come across these days in the market. I'll make use of this as an antique exhibit.
