摘要： In a communications system having a plurality of stations interconnected by a two-line circuit, in which the two-line circuit consists of a data bus circuit for transmitting a series of data bits between at least one sending station and at least one receiving station of the plurality of stations and a clock bus circuit for transmitting clock signals in synchronism with each of the data bits; the data bus circuit sends a signal or a command requesting the receiving station to enter a standby or an execute state after taking in data supplied, while a logic value on the clock bus circuit is fixed. In more detail, the sending station transmits signals to make at least one of the receiving stations enter the standby state after taking in data and then sends data to another receiving station, after which the sending station sends a signal or command to make both the first and second receiving stations simultaneously enter the execute state. The signal or command requesting the standby or execute state is added at the end of a data packet containing a series of data. The data packet includes data to be transferred to the receiving station and an address of the receiving station.

摘要： A digital audio disc player is equipped with a tracking/focus servo mechanism which automatically controls the tracking and focusing of a light beam projected on a disc. The vibration of an automobile or other vehicle containing the player is detected so that, when there is a significant amount of vibration, the control sensitivity of the tracking/focus servo mechanism is increased to prevent the occurrence of tracking and focusing errors.

摘要： A signal processing circuit which can be used, for example, as a playback equalizer is formed in a semiconductor integrated circuit with a main path and a side path arrayed between the input terminal and the output terminal of the integrated circuit. The signals at the ends of the main and side paths are added together to obtain the output signal for the signal processor. A filter in the main path determines its frequency characteristics. On the other hand, a variable gain control means having substantially flat frequency characteristics is inserted in the side path and its gain can be changed in response to control data to control the output signal of the signal processor.
