Title: Field controller of field control type dc motor
Inventor: YAMAMOTO NOBORU
IPC: H02P7/282
Filed: 1984-12-04
Abstract: PURPOSE:To suppress the generation of a surge by controlling to interrupt a field switch after a field current is reduced at stop controlling time. CONSTITUTION:An AC switch 2 is opened at the stop control starting time due to the recovery of a master relay, and starting resistors 41-43 are then sequentially closed. Here, a relay 12 is reset by the opening of the master relay and the switch 2, and the outputs of amplifiers 112, 113 become zero. Then, a relay 13 is reset by the opening of a contactor 93, and the output of the amplifier 114 becomes zero. Thus, the output of a thyristor converter 116 is controlled to be reduced, i.e., the field current is reduced. After the time limit T of a timer relay is elapsed, a field switch 6 is controlled to be opened. Thus, the load capacity of a surge protecting element can be alleviated.

In the case the human being detecting signal is transmitted and only when the signal from the luminance sensor 14 is the Low signal, does the signal transmit processing circuit 17 a lighting signal to a lighting circuit 12a.  In response to that, a light-emitting part 121 is lighted only for a prescribed duration from the leading up of the human body signal and then extinguished. Moreover, plug blade-insertion holes are formed in the surface of a box shaped body 10 and plug blade-receptions 11a are formed in the inside, so that plug blade-insertion inlets are provided, even in the case this foot lamp 1 is inserted into a receptacle in the wall face.

Abstract: PURPOSE:To attain facsimile communication such as polling reception by selecting one of plural selection signals based on a detection output representing the presence of an original and the hook state when one of the plural selection signals stored with respect to one input data is selected and selecting a facsimile selection signal even when no transmission original is available. CONSTITUTION:A system control section 1 discriminates the state of a handset 13 by an off-hook sensor 14 through the depression of a selector switch 4A of an operation section 4. In the case of on-hook, an original presence sensor 10 discriminates the presence of a transmission original 11. When the original is in existence, a destination telephone number for facsimile communication is read from a RAM 6 and a selection signal is sent from an NCU 8 to a telephone line 12 to implement prescribed transmission. When no original is in existence, the destination telephone number is read and the reception is implemented. On the other hand, in the case of off-hook, the presence of the original 11 is discriminated. When no original is placed, a talking destination telephone number is read and the usual telephone set mode is set. A selection signal is properly selected to implement the communication in this way.
