    • An external solenoid positioned external to a tire, and an internal solenoid provided inside a valve of the tire, which transmits and receives power by an alternating magnetic field in a predetermined high frequency band that generates an induced alternating current in the internal solenoid, is used as a new source of power for a tire pressure/temperature detection device instead of a battery. If the alternating magnetic field in a predetermined high frequency band is well matched to the physical structure and electrical structure of the tire, then, in the space between the tire and a wheel, an induced alternating magnetic field component is distributed that is substantially parallel to the axis of rotation of the tire. If the internal solenoid is matched to the direction of maximum magnetic field reception, when the tire rotates, and when the position of the wheel is stopped, substantially stable power may be received.

    • A transistor is connected to form a diode and connected with another transistor so that the base and the emitter is connected to the base and the emitter of the other transistor, respectively, thereby to constitute a partial current mirror. A plurality of the partial current mirrors thus constituted are serially connected between an input terminal and a reference terminal, and an output terminal is connected to the collector of a partial current mirror which is directly connected to the reference terminal. Transistors of the same polarity are used to obtain an output current larger than an input current. On the contrary, to obtain an output current smaller than an input current, the transistors constituting the partial current mirror directly connected to the reference terminal are made to have the opposite polarity to the transistors constituting other partial current mirrors.

    • An FM demodulator having improved demodulation sensitivity, and suitable for monolithic integration. As demonstrated in various embodiments, increased sensitivity is made possible= by narrowing the demodulation band on a low frequency side. According to the various embodiments, a monostable multivibrator or first pulse generator receives an input signal and provides an output having first and second states having a combined duration equal to one period of the input signal, or alternatively equal to one-half period of the input signal. A second pulse generator, responsive to the output of the first pulse generator, generates another output having third and fourth states whose combined duration is the same as the combined duration of the first and second states. Demodulation is accomplished finally through a low-pass filter, which integrates the output of the second pulse generator.
