On Planetary Gear Type Alternating Torque Generator

Bulletin of JSME, 1966
This paper describes the equipment that generates and alternating torque by the action of unbalanced masses attached on planetary gears revolving around a sun gear. Each unbalanced mass that revolves around both the sun gear and the planetary gear axis produces a centrifugal force regarding the sun gear axis and another centrifugal force and a Corioli ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.
