Title: Train position detecting system
Inventor: SATO SHUJI
IPC: G01S19/41
Filed: 2009-01-19
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a multipath error in effectively detecting a train position with a simple constitution, by making the most use of a condition such as a railroad field.  <P>SOLUTION: One or more reference stations 11 arranged on the ground for receiving a satellite signal from a satellite 24, selects the predetermined number of satellite combinations from the received satellite signals, and calculates the position of the reference station 11 from the selected satellite signal, and generates and transmits high precedence satellite combination information being a combination list of the satellite of a small error to a train 13. A pick-up device of the train 13 receives the satellite signal from the satellite 14, and receives the high precedence satellite combination information generated by the reference station 11, and selects a satellite combination of becoming small in a position error from the received satellite signals, and calculates a position of the train based on the satellite signal received by using the selected satellite signal.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Magnetostrictive torque sensor
Inventor: SHIMIZU YASUO
IPC: G01L3/10
Filed: 2009-01-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a simply-structured magnetostrictive torque sensor in which demagnetization of its rotary shaft can easily be realized.  <P>SOLUTION: In the magnetostrictive torque sensor of an electric power steering system, a demagnetization means M2 can supply an AC current to coils 40A, 40B and demagnetizes the rotary shaft so as to prevent torque detection accuracy from degradation, even if the magnetization of the rotary shaft may reduce the torque detection accuracy. In this case, the use of those coils 40A, 40B for torque detection as the ones for demagnetization enables reduction in number of parts and simplification of structure and also mutual impact between the power distribution to the coils 40A, 40B for demagnetization and the power distribution to the coils 40A, 40B for torque detection can be avoided because a switching means 57 switches the operations of a torque detection means M1 and the demagnetization means M2 based on a torque detection signal VT3. Additionally, the demagnetization of the rotary shaft can be achieved only as required, because the rotary shaft when magnetized activates the demagnetization means M2.  <P>COPYRIGHT: (C)2009,JPO&INPIT
