Title: Occupant's physical features judging method
Inventor: NAGAI MAKOTO
IPC: B60N2/90
Filed: 2002-04-18
Abstract: <P>PROBLEM TO BE SOLVED: To accurately judge a physical features of an occupant according to the weight of the occupant.  <P>SOLUTION: A load sensor detects the weight the occupant who sits on a seat of a vehicle so that a physical features of the occupant can be judged. The weight of the occupant detected by the load sensor is allocated to a plurality of areas which are set corresponding to status (adult, child, child seat, and vacant seat) at predetermined time intervals. The final status is determined according to the number of status allocated to the each area during a determination time which is longer than the predetermined time interval. For example, if 7 instant statuses show adult during the determination time which is 10 times longer than the predetermined time interval, the final status is determined as adult. Therefore, an occupant's physical features can be accurately determined without influence of changes in the load sensor output due to noises and a temporary acceleration.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a small-sized high-output armature.  <P>SOLUTION: The coil winding pitch of a three-phase armature is balanced at 2π/3 of an electric angle. In this condition, there is small space for arrangement of field winding, so it is difficult to secure sufficient excitation AT (ampere turn), but the space for field winding 9 can be secured (the space between adjacent second and third teeth 74 and 75 is secured largely) by bringing the teeth of phases on both sides near the center as against the center phase as shown in figure 4, as stated above, thereby making the winding pitches of three phases unequal (not more than 2π/3 of an electric angle). What is more, there is no problem by making the pitch into 2π/3 of the electric angle without changing the center of the tip width T of the tooth as stated above, thereby enlarging the circumferential width of the tip since the three phases become unbalance due to the inequality of the winding pitches of the three phases.  <P>COPYRIGHT: (C)2004,JPO
