Abstract: PURPOSE:To accurately control a speed of a motor in conformity with a change in speed, by a  method wherein a delay of a current speed of a motor for spacing than a reference speed is  discrimated to control a motor drive current based on the result. CONSTITUTION:After a sign curve signal S1, obtained through running of a motor 88, is pulse- shaped, a pulse period is measured and is inputted as a turning frequency information S10 to a  comparision circuit 40. Meanwhile, a reference period information S11, corresponding to a specified motor speed, is outputted from a processor 29, and the two information S10 and S11 are  compared by a comparision circuit 40. Based on the comparision information S13, the processor  29 renews a motor current information S7 of a resistor 32 for D/A. The value is converted  into a signal S9 of an analogue amount by a D/A converter 33 to compare it with an analogue  amount S8 of a motor current, detected by a resistor 34 for detecting a current, by means of a  comparision circuit 31. Based on the result, a motor 30 is increased and decreased in a drive  current by a drive circuit 30.

Title: Remote supervisory and controlling equipment
Inventor: KATO HIROSHI
IPC: H02J13/00
Filed: 1986-03-19
Abstract: PURPOSE:To transmit split information and to speed up running and maintenance by transmitting information on the trouble in a transformer substation to a master station with the aid of a bit signal according to the prescribed sequence. CONSTITUTION:Interruption information and double trouble information at every automatically interrupted equipment are transmitted from a slave station to the master one according to the prescribed sequence. If a breaker is automatically interrupted due to double troubles, the slave station side fetches the condition for displaying the automatic interruption and double troubles at every circuit from a distribution panel, and transmits automatic interruption information to the master station. The double trouble information is stored in the bit transmission circuit of the slave station until the automatic interruption information is completely transmitted, and the former is transmitted to the single wires of connection wires A and B while the connection wires are idle upon the completion of the transmission. The bit signal is synchronizingly received by a reception circuit in the master station and that in the slave station, thereby deciding the double trouble information.

Title: Magnetic field induction cable for underground joining
Inventor: YAMAGUCHI HIROAKI
IPC: G01C15/00
Filed: 1990-03-08
Abstract: PURPOSE:To detect necessary magnetic fields only to increase the joining accuracy when a tunnel is excavated by generating unnecessary magnetic fields at opposite sides of a rectangular loop behind an excavator and necessary magnetic fields at the front face of the excavator. CONSTITUTION:A rectangular loop 10 has eight cornering points A1-D1 and A2-D2. The selections defined by the cornering points A1, B1 and C1, D1 are formed at the front face of an underground excavator 1. When a electric field is impressed, the section A1-B1 generates a magnetic field G2 to be detected, while the section C1-D1 generates a magnetic field G4. Since the other sections (A1-A2-power source 6-D2-D1, B1-B2-C2-C1) generate unnecessary magnetic fields, the sections A1-A2, B1-B2, C2-C1 and D2-D1 are arranged at right angles to the front face of the excavator 1, and magnetic fields G11, G31 are made different in direction. These sections are provided behind the excavator so as not to be detected by a magnetic sensor. Accordingly, a magnetic field induction cable for underground joining which detects only the necessary magnetic field is obtained.
