A rotor magnet 4 comprises a plurality of pairs of magnetic poles coaxially with the magnetic induction sets 1, 2. In a control circuit, a two-phase current waveform output is controlled, two sets of Hall detecting elements 51, 52 are installed, and the exciting current of the coils 13, 23 is controlled. In addition, the Hall detecting elements 51, 52 are formed in such a way that their positions are fixed so as to become a mechanical angle phase difference.  Then, on the basis of a time difference in which the Hall detecting elements 51, 52 detect a change in the magnetic field of the rotor magnet 4, the magnetic induction sets 1, 2 are formed in such a way that their exciting currents become a fixed electric angle phase difference.

Filed: 1985-09-26
Abstract: PURPOSE:To enable penetration of ink into recording paper to be prevented and ink to be easily erased by providing a hydrophobic ink layer on a substrate and a hydrophilic penetration preventive layer which softens or melts at predetermined temperatures on an ink layer. CONSTITUTION:If a thermal head 5 is partially heated in accordance with a recording signal, a binder of an ink layer 1b and a penetration preventive layer 1c in such a heated part softens or melts and subsequently, the ink layer 2d1b and the penetration preventive layer 1c are separated from a base film 1a and are transferred faithfully to recording paper 2. Thus desired characters and symbols 2b are recorded. The recorded characters and symbols 2b are composed of the ink layer 1b of thermal transfer medium 1 and the penetration preventive layer 1c. These layers soften or melt during recording operation, but are not mixed because off their different properties. For this reason, ink of the ink layer 1 transferred to recording paper does not penetrate into the recording paper, so that it can be easily erased by adhesive tape, etc.

Title: Image binarization method, image binarization device and record medium
Inventor: YOSHIDA YASUNARI
IPC: G06V10/28
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent a pattern appearing when a pixel density transits to a medium tone area between a minimum density and a maximum density from a uniform pixel area with a minimum or a maximum density. SOLUTION: A pixel with a minimum density that is taken by a medium tone image is binarized to be OFF without fail and a pixel of a maximum density is binarized to be ON without fail. To a pattern of a binarization error arrangement in the main scanning direction caused in pixels with minimum or maximum density so as not to cause a uniform error arrangement in the main scanning direction, increase/decrease processing by a correction value (a) is conducted by the processing in the steps S142-S148 to change the pattern gradually into an arrangement pattern IE[pos] of ununiform numerals. Thus, a uniformized error spread to pixels of each line is prevented. Thus, a uniform error is not distributed to a head of an area consisting of only medium tone density and pixel positions to be ON are properly disturbed to prevent appearance of a pattern degrading the image quality.
