Abstract: A signal receiver for displaying received broadcast electric waves including: a first memory for storing as a past record information representing whether the signal receiver was previously subjected to initial setup, an alarm device for alarming the necessity of initial setup of the signal receiver when the connection of a power source plug to an external power source is detected and no past record exists in the first memory, whereby a user can surely perform the initial setup, a second memory for holding the initial setup frame displayed on the display device after a response to the alarm of said alarm device is received or at the same time when the alarm is made, a third memory for storing district codes and reception channel groups corresponding to the respective district codes as a district code comparative chart district, and a tuner with which when a district code is input on the initial setup frame, the reception channel group corresponding to the district code thus input is read out and a channel con
Abstract: An elevator cage control apparatus includes a brake coil energized and deenergized by start and stop command signals to move and restrain the cage, respectively. A current detector detects current flowing through the brake coil. A counter counts a time interval beginning at generation of the stop command signal and ending when current in the brake control gradually decreasing increases instantaneously and a time interval beginning at generation of the start command signal and ending when current in the brake coil gradually increasing decreases instantaneously. A memory stores the counted time intervals. A drive command issuer commands a motor driving circuit to stop and start the cage, after the counted time intervals stored in the memory have lapsed, respectively.
