Title: Monostable electromagnet
Inventor: HAYASHI KAZUTSUGU
IPC: H01F7/14
Filed: 1989-12-25
Abstract: PURPOSE:To apply a monostable electromagnet to deviated spring load without requiring a working spring by installing a permanent magnet, which is arranged near the contacting and separating section of an armature and the direction of magnetization of which is approximately perpendicular to the direction of movement of the armature. CONSTITUTION:Permanent magnets 4 are fixed to another end section of a yoke 1 and arranged near a contacting and separating section 7, magnetic poles S are magnetically coupled with the inner side faces of both end sections of an approximately U-shaped auxiliary yoke 9, the direction of magnetization is made approximately perpendicular to the direction of movement of the contacting and separating section 7, and the magnetic poles N of the permanent magnets 4 are faced oppositely to the side sections of an armature 3. Consequently, magnetic flux PHI1 flows through the armature 3, the yoke 1 and the auxiliary yoke 9 by the magnetizing force of the permanent magnets 4, and force attracting the armature 3 in the return direction hardly works. When magnetic flux PHI2 is made to overlap magnetic flux PHI3 generated by exciting a coil 2, attraction force to the operation side of the armature 3 is increased, thus reducing the power consumption of the coil 2. Accordingly, a monostable electromagnet can be applied to deviated spring load without requiring a working spring.

IPC: G06T7/20
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To directly recognize an image with high precision, where two or more colors coexist, while using a simple pattern matching method. SOLUTION: Two or more discrimination designating colors are simultaneously designated in a mask area MSK which is set on a pixel plane SC so as to be movable, the coexistence of the pixels of the respective discrimination designating colors in the mask area is decided to be necessary and required for a pattern condition and it is judged whether the pixels of the respective discrimination designating colors are adaptive to the pattern condition or not in the mask area which is set on the pixel plane. Thus, pattern matching (adaptation) is executed in a state to simultaneously detecting two or more colors of pixels in the mask area MSK so that the image where two or more colors coexist is directly recognized with high precision.  Besides, when the plural numbers, positions and discrimination designating color pixels are included as the condition for discrimination, the condition including at least one of their correlative arrangement relations is used so that processing contents are simplified and also adaptation to a real-time processing is easily attained.
