Title: Detection and control device for transmission fault
Inventor: YOSHIHARA SEIICHI
IPC: H04B17/00
Filed: 1984-02-10
Abstract: PURPOSE:To simplify the detection/control system as well as the circuit constitution for a transmission fault by controlling the power supply voltage of the circuit at the first stage of a power amplifying part after detecting a faulty working of said power amplifying part and lowering the transmission output. CONSTITUTION:The power supply voltage of a power supply terminal 4 is supplied to the circuit at the first stage of a power amplifying part 2 via a transmission working detecting part 5 and a power supply control part 14. An operational amplifier 9 for comparison compares the power supply voltage with the voltage VN of a node 17. The voltage of a node 19 is higher than VN in a transmission unable mode. As a result, the output of the amplifier 9 is set at 0 and then delivered to a transmission working deciding part 11 as a transmission working unable detection signal. In the same way, the output of the amplifier 9 is set at 1 in a transmission working mode and delivered to the part 11 as a transmission working detection signal. Thus the circuit at the first stage of the part 2 is controlled by the parts 11 and 14, and the power supply voltage is kept at a normal level. In case a fault occurs in a transmission working mode and transmission start signal of a terminal 10 is turned off, the output of the part 11 is set at 0. Then the power supply voltage supplied to the part 2 is reduced down to a level divided by resistances 8 and 15. Thus the transmission output is lowered.

IPC: B61F5/30
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To provide an axle supporting structure which can be suitably employed by the DDM driving type bogie for a rolling stock. SOLUTION: This bogie for a rolling stock 100 is so constituted that an axle 40 is supported by an axle box 32 provided for an axle beam 30 in such a way that it can be rotated, and concurrently, driving reaction force to be applied to the axle 40 by a driving motor 60, is transmitted to a bogie frame while relative displacement between a torque arm 70 and the axle beam 30 is being absorbed by using a driving reaction force transmitting member 80 interposed between the torque arm 70 rotated integrally with the axle 40 and the axle beam 30. By this constitution, even if the bogie frame is rolled, great twisting torque caused by an angular difference between the paired right and left axle beams 30 will never be applied to the axle 40, and a mechanical portion suspending the rotation of the axle 40 by means of driving reaction torque can thereby be prevented from being damaged.
