Title: Fuel reforming apparatus and hydrogen generation method
Inventor: HIRABAYASHI TAKESHI
IPC: B01J23/63
Filed: 2002-08-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide techniques to improve the efficiency of hydrogen generation in a fuel reforming apparatus.  <P>SOLUTION: The fuel reforming apparatus 10 is equipped with a first catalyst 12 and a second catalyst 14. The first catalyst 12 contains metals including Rh carried on a carrier containing at least one of CeO<SB>2</SB>and Al<SB>2</SB>O<SB>3</SB>. The second catalyst 14 contains metals including Rh carried on a carrier containing ZrO<SB>2</SB>. When a fuel for reforming at high temperature and steam are supplied to the fuel reforming apparatus 10, the steam reforming reaction proceeds to generate hydrogen. Since the steam reforming reaction is endothermic, the inner temperature of the fuel reforming apparatus 10 is higher in the upstream side. Since the first catalyst 12 has higher efficiency of hydrogen generation in a higher temperature range compared to the second catalyst 14, the hydrogen generation efficiency in the fuel reforming apparatus 10 as a whole can be improved by disposing the first catalyst 12 in the upstream side of the second catalyst 14.  <P>COPYRIGHT: (C)2004,JPO

Title: Electric power steering device
Inventor: TAMAIZUMI HARUTAKA
IPC: B62D113/00
Filed: 2002-08-21
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the steering load for a driver in reversing the operating direction of an operation member.  <P>SOLUTION: A basic target current value is determined on the basis of the steering torque T and a speed of car V. A corrected target current value is determined by adding various correction values to the basic target current value in an adding part 25. An electric motor M is driven and controlled on the basis of the corrected target current value. A turn controlling part 24 creates a correction value to reduce high steering load caused by the inertia of the electric motor M and a steering mechanism 3 in steering to reverse the steering direction of the steering wheel 1. Concretely, when the reversing of the steering direction is detected, the correction value is determined on the basis of the steering acceleration at that time, and the change of a steering angle or the steering torque from the detection of the reversing.  <P>COPYRIGHT: (C)2004,JPO

Title: Magnetic sensor
Inventor: MOMOSE SHOGO
IPC: G01R33/02
Filed: 2002-08-23
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a magnetic sensor at a low cost wherein error is small to fluctuation of environmental temperature using a simple constitution.  <P>SOLUTION: A magnetic core SC is formed of core material having characteristic, wherein the permeability increases with the temperature rise. Temperature characteristics, regarding the conductivity of a member C to be detected, are corrected by using temperature characteristic regarding permeability of the magnetic core SC, and output from a detection coil 4 is stabilized. By the above constitution, when the temperature of usage environment increases, the output value of detection signal is corrected, since the permeability of the magnetic core SC will increase, even if the output value of the detection signal is lowered by the decrease in the eddy current generated by magnetic flux ψ. Thus a proper detection signal can be obtained suitably, irrespective of the changes in the temperature environment.  <P>COPYRIGHT: (C)2004,JPO
