Abstract: Apparatus to navigate connection among a controller housing and disk device housings which constitute a storage device. The controller housing, the disk device housings, and the like are stored in a storage device housing and are connected by ENC cables according to a typical connection method as preparation. A connection information file, which defines a connection state among respective connectors, is inputted to the controller housing. A controller lights or blinks LEDs of connectors, to which the ENC cables should be connected based on the connection information file, in a connection order. The controller navigates connection by sequentially lighting the LEDs of the connectors, which should be connected, in this way.

Abstract: A code division multiple access (CDMA) mobile communication system with improvements to permit stable reception with a minimum of bit error. The system includes a base station and a mobile station for communicating with the base station. The mobile station includes an oscillator, a radio frequency demodulator for demodulating a radio frequency band signal received from the base station by use of a first signal from the oscillator, a radio frequency modulator for modulating a second signal to be transmitted by use of the first signal from the oscillator, and an antenna for receiving the radio frequency band signal transmitted from the base station, and for transmitting the modulated second signal to the base station. An oscillation frequency of the oscillator is controlled by use of a change of phase shift detected using the demodulated radio frequency band signal received from the base station.
