摘要： PURPOSE:To obtain a light wt. and small-sized magnetic shield device, by preventing the effects of leakage flux generated from reactors on terrestrial signal facilities by dividing one reactor into two ones and by devision their mounting method. CONSTITUTION:A reactor loaded on a car is divided into two reactors 2, 3, which characteristics and capacity are same, each axis is directed in the rail direction, the car progressive direction, and both reactors are installed onto the car so that the centers be positioned onto a straight line crossing at right angles with rails while connecting both reactors so that magnetomotive force each be formed in the arrow head b, c directions when fixed currents are flown to each reactor 2, 3, thus selecting the polarities of the reactors that the DC leakage flux of the reactors 2, 3 at both sides mutually denies. This method can ensures a comparatively small quantity of shields as compared to the case when the reactor is mounted as one machine, and can attain the production of small-sized and light wt. whole reactors.

摘要： PURPOSE:To design an electrical supply device of a small size by constituting such that an induction motor is employed as a power source for running a cable, a linear induction motor is employed as a power source for a departure- arrival push-feed device, and electricity is supplied from a common DC power source to an inverter attached. CONSTITUTION:A cable 4 routed between a high speed (drive) pulley 3 and a driven side pulley (not shown) and circularly operated in the direction of the arrow is guided downward when it comes to a terminal by means of a guide roller 5. This causes a cable gripper 7' to release the cable 4 and to be run by a lower roller 8 on a cable gripper guide rail 6. In this case, while a primary sides 20A, 20B of linear induction motors 1, 2 respectively of deceleration and acceleration sides are arranged on arrival and departure sides, a secondary side 21 is arranged on the top surface side of the cable gripper 7'. The high speed pulley 3 is rotated via a speed reduction device 2 with an induction motor IM driven via a variable voltage, variable frequency inverter.

摘要： PURPOSE:To suppress to a large extent a noxious high voltage component while a switch is closed by a method wherein a double wave of 1/2 of the basic voltage frequency is removed by filtration. CONSTITUTION:Series resonance circuits 4, 5, 6, 7 having respectively frequencies 0.5, 1.5, 2.0 and 2.5 times that of a supply frequency are connected to an output terminal in parallel. In so doing, noxious high frequency voltage appearing at the output terminal immediately after a switch 3 is closed is shortcircuited, whereby the same frequency as the supply frequency and its 3rd, 5th, 7th harmonic voltage mainly appear. Thus the harmful component is minimized and this makes it possible to construct an iron resonance type constant voltage transformer from which stabilized output voltage is obtainable.

摘要： PURPOSE:To eliminate the affection of main smoothing reactors disposed at both sides of a main filter reactor to a ground signal facility by disposing the centers of the respective reactors on a rectilinear line perpendicularly crossing with rails. CONSTITUTION:Main smoothing reactors 7, 8 are divided and disposed at both sides of a main reactor 3, and the respective reactors are constructed to be located at the axial centers on a rectilinear line with respect to the central axis X of a ground loop coil 13 provided between rails. The respective reactors consist of coils 3-1, 7-1, 8-1, reactor core magnetic shields 3-2, 7-2, 8-2, nonmagnetic magnetic shields 3-3, 7-3, 8-3. The leakage magnetic fluxes produced at the respective reactors 3, 7, 8 are so selected in polarity as to cancel with each other so as not to adversely affect the ground signal facility.

摘要： PURPOSE:To make easier the setting of device which gives alarm for stop or decrease of coolant flow, by setting a temperature detection device at close place of heat source placed in the flow path of coolant. CONSTITUTION:Cooled device 14, thermister type temperature detection device 111 and electric heater 112 which has a low resistance, are set in the air flow tube 1. The device 14 is cooled by cold air sent by fun 15 in the tube. An alarm is released by the alarm device 12 when the temperature detector 11 detected a temperature being more than the fixed value, and also when the detector 111 detected a temperature being more than the alarm temperature, which is caused by decreasing coolant flow due to some troubles of fun.

摘要： PURPOSE:To make it possible to control in a stabilized manner with a simple constitution by employing a linear induction motor for a power source of a departure-arrival forwarding device and by controlling currents to multiple coils constituting the primary side of the motor by means of a variable voltage, variable frequency inverter. CONSTITUTION:A cable 4 routed between a high speed (drive) pulley 3 rotated with an induction motor 1 and a driven side pulley and is circularly operated is released, when it reaches a terminal A, from a cable gripper 7' which is run by a lower roller 8 on a guide rail 6. In this case, primary sides 20B of the linear induction motor of deceleration and acceleration sides are arranged parallel to the guide rail 6 on both departure and arrival sides of the terminal A while a secondary side 21 is arranged on the top surface side of the cable gripper 7'. The primary side 20B is divided into multiple coils 24a-24k each of which is energized and controlled by means of a variable voltage, variable frequency inverter 26 via each of respective switches 25.
