The present invention relates to a semiconductor integrated circuit and a wireless communication apparatus that can be reduced in size without deteriorating a receiving sensitivity and a transmission efficiency. Communication with an external reader/writer and an external non-contact IC card is carried out through a common antenna 211. The signal received from the external reader/writer or the external non-contact IC card through the antenna is supplied to an ASK demodulation circuit 149 and demodulated. The signal received from the external reader/writer is full-wave rectified and smoothed by an full-wave rectification and smoothing circuit composed of diodes 231, 232 and a capacitor 233, and the power obtained from the full-wave rectified and smoothed signal is supplied to respective units of a semiconductor integrated circuit 101. The present invention can be applied to a mobile phone.

An electromagnetic induction type processing apparatus includes a coil and a functional device. The coil is configured to generate electromotive force from a magnetic field supplied from the outside. The functional device is configured to operate with the electromotive force and containing conductive substance having a conductivity with which eddy current to be generated in the conductive substance by the magnetic field supplied from the outside is suppressed such that the lowest electromotive force for operation of the functional device is assured regardless of a magnetic field generated by the eddy current and acting in the opposite direction to that of the magnetic field supplied from the outside.

A highly fashionable finger ring consisted of replaceable ring-shaped members is provided. A finger ring has ring-shaped members 1 and 2, each ring-shaped member 1 and 2 being decoupled in the center part, and between the both ends of a circular arc part 9(10), an opening 3(4) is produced by being twisted the both ends in a counter direction. Each end of the first ring-shaped member has the jewelry part 5 and 7 respectively, while each end of the second ring-shaped member having the jewelry part 6 and 8 respectively. The jewelry part 5(6) is relatively large, while the other jewelry part 7(8) being relatively small. Relatively large jewelry part 5(6) may be stereoscopic and large. When putting on a first and second ring-shaped member 1 and 2 in a manner opposed each other, a relatively large jewelry part 5(6) of either one of the two ring-shaped members fits in the opening 4(3) of the other ring-shaped member, seeming like one finger ring. Each ring-shaped member 1(2) is replaceable and can be combined extremely easily. Moreover, each ring-shaped member can be used individually.

An identification level control method and an optical receiver are disclosed to determine an optimal identification level in a simple structure without clock extraction. In the identification level control method, an identification level supplied to a limiter amplifier is changed from a lower bound to an upper bound thereof and is stored together with an output average of the limiter amplifier. Then, a first average and a second average are set based on the output average. A first identification level corresponding to the first average and a second identification level corresponding to the second average are obtained, and an optimal identification level is computed based on the first identification level and the second identification level, and is supplied to the limiter amplifier.
