There is provided a mobile station device capable of effectively performing interference suppression symbol synthesis while suppressing the lowering of the transfer rate when using the repetition technique in multi-carrier communication. The inner part and the outer part are configured with torque receiving means for transmitting a torque applied to the outer part to the inner part. One or more over-layer sections of a second electrically conductive material each are electrically connected by a bond to at least one of the first connector of an LED die. In a first surface of the device, each source region of the main device and the subsidiary device is formed so as to be insulated from each other through an isolation region. Next, the system generates and stores new checkbits in a functioning memory component, wherein the new checkbits provide single-error-correction and double-error-detection for erroneous bits in the block of data, but do not provide for detection and correction of a failed memory component.
