A fabricated toy is equipped with a plurality of toy component members having predetermined shapes, a detecting device for detecting the assembly state of these toy component members, and a sound generating device for emitting sounds in accordance with the assembly state of the toy component members detected by the detecting device so that when the toy component members are correctly assembled, a specific shape is completed. In this fabricated toy, the sound generating device generates the sounds of mutually different kinds in the cases where the toy component members are correctly assembled and incorrectly. Infants, therefore, can play at the assembly of the toy for a long period of time, without losing their interest in the toy, and the toy, which is "a horse" or "a frog", can also serve as educational stuff for assembling correctly the toy into the shape of the animal.

There is provided a semiconductor device which is simple in configuration and resistant to tampering. A user input unit receives an authentication code input by a user. A CPU determines whether a user's access is legal based on the input authentication code and activates an enable signal if the user's access is legal. A normal row decoder decodes the row address specified by the CPU and selects a normal memory cell of any row based on the result of decode. A redundancy row decoder prohibits the selection by the normal row decoder when the specified row address agrees with the row address of a predetermined normal memory cell only if the enable signal is activated and selects a redundant memory cell of any row.

摘要:
A transmitter in a mobile communication system code-multiplexes transmission symbols together with spreading codes, performs inverse Fourier transform and transmits the result from multiple transmit antennas. A receiver in the mobile communication system performs Fourier transform on signals received at multiple receive antennas, extracts signal components of individual subcarriers and estimates symbols in accordance with a QR decomposition algorithm. A unitary matrix is derived such that a product of a spreading matrix including spreading elements as its elements and a channel matrix representing radio channel states is equal to a product of the unitary matrix and a triangular matrix. A reception vector, a unitary matrix and a triangular matrix are used to estimate symbol candidates transmitted from individual transmit antennas.
