Thursday 1st October 1998

Our living environment is now being built to enrich the welfare of old persons with due consideration. We have developed a new elevator for personal houses based on this social demand. We have succeeded in noticeably compacting the control circuits and reducing electromagnetic noises at a higher switching frequency by utilizing a reduced instruction set computer and insulated gate bipolar transistors. We have simplified our control system by integrating its power supply for control circuits to have successfully installed the control panel in the hoistway.
