摘要： PURPOSE:To make it possible to detect the position of a traveling body with precision by correcting a shift in target position by electrically changing the set value of a reference signal without remodeling facilities on the side of the ground or traveling body. CONSTITUTION:On the ground side, cross inductive radio line 16 with cross points 10a-12a corresponding to target points 10-12 is laid, transmitter 13 is connected to line 16 via approach cable 14 and matching transformer 15, and at the terminal of line 16, terminating resistance 17 is arranged. On traveling body 1, two receiving antennas 18 and 19 are mounted at a run-directional interval. Antennas 18 and 19 are connected to signal processing circuit 20, phase-difference A-D converting circuit 21 and coincidence deciding circuit 22, which connects with reference-signal setting circuit 24 which sets and outputs a reference signal together with the output of absolute-address detecting circuit 23. The above-mentioned constitution makes it possible to detect a position corresponding to the target point of traveling body 1 with precision.

摘要： PURPOSE:To keep the dropping quantity of a free loop constant by controlling a rolling operation by a speed factor of the reference side and/or the driving side obtained by passing the front end of the free loop between two photoelectric detectors. CONSTITUTION:The speeds V1, V2 of a strip at the reference side and the driving side are detected to obtain the variation of the front end of a free loop by integrating the difference between two speeds. The speed V2 at the control side is corrected by a speed correcting signal prepared in accordance with said variation to control the position of front end of the free loop. Before starting the positional control, the speed V2 at the control side is speeded up by adding a bias value existing at the control side to the V2 to operate rolling. And the strip is passed between two photoelectric detectors 1,2 to decide a speed detecting factor at the reference side and/or the driving side. Then the operation is controlled by the speed detecting factor. Thus the dropping quantity of the free loop is kept constant, and labors required for a test running and a readjustment at the time of routing repairing are saved.

摘要： PURPOSE:To detect magnetic metal pieces existing in a raw material including magnetic substances by setting a subcoil coupled with a main coil electromagnetically in parallel and connecting an artificial load resistance having a proper resistance value in said coil. CONSTITUTION:A detecting coil 1 is set so as to surround a conveyor belt 3, said detecting coil 1 being connected with an oscillation circuit. The detecting coil consists of a main coil 1, a subcoil 2 coupled with said main coil 1 in parallel and electromagnetically and an artificial load resistance (r) connected with said subcoil 2. When the raw material 4 containing magnetic substances is carried by the conveyor belt 3, the mutual inductance of coils 1 and 2 increases though the resistance loss of coil 1 decreases and the current which flows through the artificial load resistance (r) increases and the load of the coils 1 also increases. Accordingly, a proper selection of the load thereof is capable of offsetting each other. Therefore, it is possible to detect the existence of iron pieces in the raw material without any influence of the magnetic raw material.

摘要： PURPOSE:To restrict the range in which rate of variation in the voltage applied to a track relay is changed, by providing an insulating reactor transformer LT having a low impedance in a track circuit. CONSTITUTION:Rails 1, 2 are divided into a plurality of sections through provision of insulators 3, and insulating reactor transformers LT are connected between the current feeding rail and current transmitting means or otherwise between the current receiving rail and track relay means. If a trouble that the reactor transformer is opened is caused, transmission of current is interrupted and voltage applied to the track relay TR drops to zero, whereby safety operation of the system can be ensured.
