Title: Method of driving and controlling stepping motor
Inventor: ITO SHUNICHI
IPC: H02P8/00
Filed: 1989-09-18
Abstract: PURPOSE:To prevent overcurrent without lowering the torque by dividing each excitation time of phase windings into two or more, widening overdrive signals upon rise of driving currents, and narrowing said signals after the rise. CONSTITUTION:The output (a) of a pulse generator 1 is entered to an overdrive generation circuit (OVDV) 2' and a distribution circuit 3. The distribution circuit 3 switches over and transmits signals (c)-(f), energizes transistors(Trs) 4a-4b in a specific sequence, and passes currents through coils 5a-5d. The OVDV 2' transmits at H during the specific time of the initial two pulses of OVDV signals b1 and b2, turns Tr's 4e1 and 4e2on through Tr's 4f1 and 4f2, and applies voltage +E1 to windings 5a, and 5c and, 5b and 5d to start a motor. The OVDV signals b1 and b2 at H are transmitted during the following two pulses. Thereby the coils are prevented from burning by an overcurrent without lowering the torque.

Title: Message communication system
Inventor: TSURUMI HIROSHI
IPC: H04B7/26
Filed: 1988-09-28
Abstract: PURPOSE:To effectively use an idle frame by transmitting message information by means of the unused frame when message information cannot be stored in an allocated frame. CONSTITUTION:Since message information are transmitted to slave stations 3-6 in a base station 1, allocation is decided for a time unit, namely, at every frame or every slot for respective slave stations 3-6. The base station 1 transmits message information to the slave stations 3-6 through an antenna 2 by the allocated frame. When the quantity of message information is too numerous for a certain slave station to transmit message information in the frame which is allocated to the slave station, a frame retrieval part retrieves the idle frame among the frames which are allocated to the other slave stations, and message information is transmitted by using the idle frame. Thus, traffic can be effectively used since it becomes unnecessary to wait for message information which cannot be transmitted until the frame of a subsequent period.
