Patent JP-H03233591-A (JP)
Title: Fixing device
Inventor: MIZOROGI TSUTOMU
IPC: G03G15/20
Filed: 1990-02-09
Abstract: PURPOSE:To eliminate a waste of electric power and an extra rise in ambient temperature and to prolong the life of a flash lamp by providing a flash control part which controls the light emission of the flash light by receiving a decision signal indicating whether the flash is required or not. CONSTITUTION:A detection part 3 outputs the decision signal 15 to the flash control part when there is not even one character or image data for longer than a time corresponding to the irradiation range of single-time illumination of the flash lamp 5. The flash control part 4 normally performs control for turning on the flash lamp 5 at each constant time, but when the signal indicating that there is no image data arrives from the detection part 3, the flash lamp 5 is inhibited from illuminating at the corresponding part of a form 13. Consequently, the waste of electric power and the extra rise in temperature are eliminated and the life of the flash lamp 5 is prolonged.

Title: Commutatorless motor
Inventor: SATO HIRONOBU
IPC: H02P6/182
Filed: 1995-02-20
Abstract: PURPOSE:To make possible the prevention of unevenness by combining windings in such a way that one phase is always unenergized, changing the combination for energization according to induced voltage generated in an unenergized stator winding, setting the number of teeth to a specified value, and putting the stator windings in three-phase connection in such a way that adjacent stator windings are out of phase and full-wave energization is feasible. CONSTITUTION:A stator 13 has projected pole teeth 14-19, on which stator windings 20-25 are formed. The stator windings 20-25 are star-connected for full-wave energization. Further, the stator windings 20-25 are connected in such a way that adjacent teeth are different in polarity from each other and teeth facing each other have the same polarity during energization. Gate signals are generated according to variations in induced voltage generated in an uunenergized stator winding. As mentioned above, the teeth are so constituted that the number of them is 3Xn ('n' is an integer of 2 or above) and adjacent teeth 14-19 are out of phase. Therefore, rotating fields are evenly distributed on the periphery of a rotor even if the energization of the stator windings is controlled in such a pattern that only two of three phases are always energized.
