The N1(s) turns of a first output winding is divided by a split ratio α into N1a(s) turns of a lower-layer first output winding and N1b(s) of an upper-layer first output winding. The lower-layer first output winding is continuously wound around all slots as the undermost layer. A second output winding is continuously wound around all slots over the lower-layer first output winding. An upper-layer first output winding is continuously wound around all slots over the second output winding. The split ratio α is adjusted only in the slots where the detection accuracy decreases. This equalize the contribution of the first output windings and the second output winding to the flux linkage, thereby achieving high angle detection accuracy.

A plurality of protruding portions each having a predetermined width in a circumferential direction are respectively provided at a predetermined interval along an outer periphery of a stator, and through-holes are formed at both ends in the circumferential direction of the protruding portions. A total length of the widths, which the protruding portions respectively have, in the circumferential direction is set equal to or less than 25% of an outer circumference of the stator. With this structure and by virtue of the through-holes, a compressive stress built up in an inner periphery of the stator due to pressing forces imposed on center areas of the protruding portions can be distribute toward the outer periphery of the stator.

An anti-hypothermia composition is provided, in particular an anti-hypothermia composition that prevents hypothermia caused by general anesthesia during surgical operations. The composition prevents hypothermia by preventing the decrease in the biological function of patients and correcting acidosis. Specifically, the anti-hypothermia composition is a preparation containing a bicarbonate ion and provided in the form of an infusion fluid. The infusion fluid preferably contains sodium bicarbonate as a major component that serves as a source of the bicarbonate ion, along with each or a combination of other electrolytes, glucose and amino acids.

In an offset cancelling circuit of a Hall element, a voltage is applied from four directions and from outside such that a current flowing in the Hall element is switched by 90°, to set a first state through a fourth state, and output voltages of the Hall element in the first state through the fourth state are averaged.

The N1(s) turns of an output winding is divided by a split ratio α into N1a(s) turns of an output winding (1a) and N1b(s) turns of an output winding (1b). The output winding (1a) is continuously wound around all slots as the undermost layer. Output winding 2, which is different in phase by 90 degrees from the output winding (1a), is continuously wound around all the slots over the output winding (1a). An output winding (1b) is continuously wound around all the slots over output winding 2. This equalizes the contribution of the output winding and output winding 2 to the flux linkage, thereby achieving high angle detection accuracy.

One high-frequency switch Qm supplied with transmit and receive signals to ON, and another high-frequency switch Qn supplied with a signal of another system to OFF are controlled. In the other high-frequency switch Qn, to set V-I characteristics of near-I/O gate resistances Rg1n-Rg3n of a near-I/O FET Qn1 near to a common input/output terminal I/O connected with an antenna are set to be higher in linearity than V-I characteristics of middle-portion gate resistances Rg3n and Rg4n of middle-portion FETs Qn3 and Qn4. Thus, even in case that an uneven RF leak signal is supplied to near-I/O gate resistances Rg1n-Rg3n, and middle-portion gate resistances Rg3n and Rg4n, the distortion of current flowing through the near-I/O gate resistances Rg1n-Rg3n near to the input/output terminal I/O can be reduced.

A PWM-signal-output circuit includes a first output unit to output a PWM signal with a first duty cycle, in a first period in which a motor starts rotating, a second output unit to output the PWM signal whose duty cycle increases toward a second duty cycle and decreases from the second duty cycle in a period from a logic level change in speed signal until its subsequent logic level change, in a second period following the first, the speed signal having a period corresponding to a motor-rotation speed and a logic level changing alternately, and a third output unit to output the PWM signal whose duty cycle increases toward that of the input signal and thereafter decreases from that of the input signal in a period from a logic level change in the speed signal until its subsequent logic level change, after the second period elapses.

By correcting a data signal based on a current flowing through an EL element when an element driving transistor which controls a drive current to be supplied to the EL element is operated in a saturation region and the EL element is set to an emission level, it is possible to realize a rapid display variation inspection and a high precision display variation correction. By providing a current measuring function on an EL display apparatus, a characteristic variation after the apparatus is shipped can be handled and corrected.

The on/off state of the transistors of the receiver switch coupled between the I/O port and a receiver port is controlled by a receiver control bias. An RF signal input port of the bias generation circuit is coupled to the transmit port, and a negative DC output bias generated from a DC output port is supplied to a gate control port of transistors of the receiver switch.
