41. Design work was undertaken by Mitsubishi, with Shinichi Matsuda designing the control circuits and Saneyoshi Hirota designing the main motor. 42. Socket outlet units with control circuits also fall within the scope of the EMC Directive 2004 / 108 / EC. 43. Historically, tone control was achieved via analog electronics, and most tone control circuits produced today still use the analog process. 44. Chinese space scientists eventually ascertained that the control circuit had failed, and this prevented Yutu from entering normal dormancy as planned, 45. By connecting them in opposite phase, the two cancel each other, so that no current is induced in the control circuit . 46. A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. 47. Other sources of reactive power that will also be used include shunt capacitors, shunt reactors, static VAR compensators and voltage control circuits . 48. Auxiliary contacts of contactors are used in control circuits and are rated with NEMA contact ratings for the pilot circuit duty required. 49. One of the men is startled and fires his gun, accidentally hitting the main control circuit on the back of the truck. 50. These are adjusted by a remote control circuit from the ground, eliminating the need for a technician to climb the antenna tower.
