IPC: H02K29/00
Filed: 1994-04-14
Abstract: PURPOSE:To generate a rotational torque by a subcoil at a dead point by a one-phase bipolar driving by a method wherein two subcoils are wound respectively in the same direction between submagnetic poles adjacent in every other position in the circumferential direction and main coils are wound in the same direction also between the individual subcoils. CONSTITUTION:A stator core 10 is formed in such a way that a plurality of core plates stamped and formed in the same shape by means of a press or the like are laminated in the up-and-down direction. It is provided with main magnetic poles 10a1 to 10a4 and with submagnetic poles 10b1 to 10b4 installed between the main magnetic poles 10a1 to 10a4. When the circumferential width of the main magnetic poles 10a1 to 10a4 is large, a drive torque becomes large, and, when the circumferential width is small, the drive torque becomes small. On the other hand, when the circumferential width of the submagnetic poles 10b1 to 10b4 is large, an auxiliary drive torque becomes large, and, when the circumferential width direction is small, the auxiliary drive torque becomes small.

Filed: 1995-03-31
Abstract: PURPOSE: To prevent generation of a black spot (a white spot in reversal developing) due to a free flocculating body in a superplasticizer by using two kinds of toners in which surface superplasticizer quantities are different from each other. CONSTITUTION: In an image forming method using two kinds of toners prepared by adding a superplasticizer onto the surface of coloring grain containing at least a binder resin and a coloring agent, surface superplasticizer quantities of the two kinds of toners are different from each other. When the surface superplasticizer quantities of the two kinds of toners are assumed to be X1, X2, a ratio of X2 to X1 is preferably 0.3-0.8. In this way, a demerit obtained when the toner with a few surface superplasticizer quantity and the toner with a great surface superplasticizer quantity are used individually is prevented, and also, a highly uniform superplasticizing property and electrostatic charge property can be exhibited because free flocculating bodies in the superplasticizer are captured by means of the toner with a few surface superplasticizer quantity.  Therefore, no deterioration, which is caused by the free flocculating body in the superplasticizer, in a frictional electrostatic charge property in an electrostatic charge member is generated, and a high quality image without any fog is outputted, while an excellent developing property and an excellent transferring property can be provided, and consequently, a high image degree is accomplished.

Abstract: PROBLEM TO BE SOLVED: To adjust a drain current without changing a gate voltage by setting a drain to a positive drain potential to the ground, setting a gate to the range between the drain potential and the potential of the ground and changing the potential of a source to the ground. SOLUTION: The drain electrode 2 of an FET 1 receives a DC voltage 3.5 V, for instance, from the positive pole of a power source and the gate electrode of the FET 1 is grounded through a resistor 5 to the ground. The negative pole of the power source is connected to the ground and a single positive power source is used as the power source. Then, resistance between the drain electrode 2 and a source electrode 4 is controlled by the gate voltage of the FET 1. Thus, the voltage applied to the drain electrode 2, the gate electrode 3, the source electrode 4 and a switch changeover terminal 7NO is not negative and becomes more than 0 V. Thus, the need of a negative power source is eliminated and the plural pieces of current consumption setting are performed only by the positive power source.

Abstract: PURPOSE: To convert the position of a float, that is externally set being movable vertically along the outer circumference of a tube, into electric resistance by magnetically coupling a driving magnetic pole piece, interlocking with the float, with an electrode interlocking with a driven magnetic pole piece that is loosely inserted into the tube being vertically movable.

As a result, electrode 12 fixed to driven magnetic pole piece 10 also ascends or descends together with float 14 to form a short circuit between resistance thread bodies 8 and 9 via sliding pieces 12a and 12b near float 14 all the time. Assuming the resistance values of resistance thread bodies 8 and 9 per unit length to be constant, the resistance value between connection terminals 4 and 5 is in proportional to the distance between terminals 4 and 5, and sliding pieces 12a and 12b, and consequently it is easy to convert the measured resistance value direct into a water level by connecting between connection terminals 4 and 5 a resistor that is not shown in the figure.

Abstract: PURPOSE:To delay power supply to an IC card until clock pulses are stabilized and to stabilize operation by adding a delay circuit to a circuit for supplying power supply voltage to the IC card. CONSTITUTION:The circuit for supplying power supply to the IC card is equipped with the delay circuit 1. When a control signal Vcc.CNT is turned to an 'H' level, a transistor(TR) Q2 is conducted, the input of an inverter integrating circuit IC1 is turned to the 'H' level, electrostatic charge previously accumulated in a capacitor C1 is discharged through a register r4, and after the passage of time t2, a C.MOS inverter integrated circuit IC2 generates an output and a TR Q4 is conducted. As the result, power is supplied from a power supply terminal Vcc to the IC card. Since power is supplied to the terminal Vcc, a clock pulse outputted from an oscillation circuit A is outputted to a terminal CLK through a transmission circuit 2. Since both electric power and a stabilized clock pulse can be simultaneously supplied to the IC card, an unstable state is not generated in the IC card.
