Title: Coil for motor and motor
Inventor: MIYAGAWA HIDEAKI
IPC: H02K3/02
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient motor with an enhanced magnetic flux density effective in motor thrust and an increased vector product of coil current and magnetic flux density. SOLUTION: A coil 5 is formed of magnetically soft material and is provided with an easy axis of magnetization in the direction of the incidence of magnetic flux. Since the coil 5 is formed of magnetically soft material and thus the magnetic resistance between permanent magnets and a stator yoke containing the coil 5 is reduced, the density of the magnetic flux 10 from the permanent magnets is increased. Since there is the easy axis, the magnetic flux from the permanent magnets is apt to perpendicularly permeate the coil 5. Leakage flux 10b, 10c which does not contribute to motor thrust is reduced, so that it can be disregarded.  For the reason, the density of the magnetic flux 10 which has become very large and the density of the magnetic flux 10a contributing to motor thrust become almost the same, and the motor thrust equivalent to the vector product of the density of the magnetic flux 10a and coil current 11 can be significantly increased.

Title: Recognition device for vehicle
Inventor: SHIMOMURA TOMOKO
IPC: G06T1/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the need to detect the whole vehicle and to securely detect the number plate even if the number plate slants by correcting an image- picked-up quadrangle into a rectangle and scaling it according to the longitudinal/lateral ratio of the number plate. SOLUTION: When the number plate 2 of a precedent vehicle 1 is perpendicular to the optical axis of a camera 3, the number plate in an image is picked up as a quadrangle having a longitudinal/lateral ratio A:B. When the number plate surface is not perpendicular to the optical axis of the camera 3, on the other hand, quadrangles as candidates for the number plate is detected in the image. Then the quadrangles are corrected into rectangles having parallel opposite sides and the rectangles are corrected to a longitudinal/lateral ratio A:B. Then the histogram at the same position in the corrected rectangle is obtained and compared with the histogram obtained when an image of the actual number plate is picked up from the front. Consequently, it is confirmed whether or not the quadrangle is the number plate.

When the logic channel number to be set is increased more than the total sum of connection limits of a low-degree acting effectively in each of B-channels for packet exchange is more than the decided logic channel number, the connection limit of higher degree by one is validated to select a B-channel. Thus, traffic decentralization is facilitated when the communication controller sets a new logic channel to utilize ISDN packet exchange.
