Title: Auto-tracking device
Inventor: HORI HIROYUKI
IPC: G11B20/06
Filed: 1994-10-06
Abstract: PURPOSE: To correct the amplitude difference between FM signals at different carrier frequencies and to suppress the fluctuation in amplitude of reproduced FM signals by using a gain-frequency characteristic correction circuit of a simple circuitry. CONSTITUTION: The FM signals reproduced from a magnetic tape 1 on which a first kind of FM signals of carrier frequency f1 are recorded and a magnetic tape 1 on which a second kind of FM signals of carrier frequency f2(>f1) are corrected in amplitude by a gain-frequency characteristic correction circuit 5 to be detected by the use of a detection circuit 7 and to obtain amplitude information for tracking phase control. From the high-frequency loss between the magnetic tape 1 and the rotary magnetic head 2 and the difference of track pitches on the magnetic tape 1 between the first and second FM signals, the amplitude of the second FM signals reproduced is smaller than that of the first FM signals and both the FM signals have amplitude fluctuation.  However, the circuit 5 has such a characteristic that the gain increases as the frequency increases in the bands of the first and second FM signals. Therefore, the amplitudes of the first and second FM signals are equalized and the amplitude fluctuation is suppressed.

Filed: 1991-09-24
Abstract: PURPOSE:To avoid useless callback by a caller by allowing the called party to set a reply disable state in advance and informing the occurrence of an incoming call to a caller station when the incoming call reaches the called party. CONSTITUTION:When the user is not resident near the communication equipment or busy with other business, the user sets switch of a reply disable setting section 6 to the state of reply disable in advance. A control section 8 analyzes a reception signal from a protocol handler 9 and discriminates whether or not the call comes to its own station, and when the call reaches its own station, it is displayed on a display section 7. Moreover, in this case, when the switch of the reply disable setting section 6 is set to the state of disable reply, the control section 8 sends data representing disable reply to the protocol handler 9. Then the disable reply is informed to an opposite station via an antenna section 1. Thus, the caller recognizes it that the called party is in the reply disable state at present and succeeding useless calling is avoided.

Filed: 1990-09-13
Abstract: PURPOSE:To facilitate the design of the system by expressing the design specifications by using a specification description model obtained by adding a conception of an abstract data type and hierarchization to a finite state machine model. CONSTITUTION:The design specifications are expressed by using a finite state machine model to which a conception of an abstract data type and hierarchization is added, based on request specifications. That is, the design specifications of the system are expressed by a finite state machine model (Finite State Machine: FSM) for catching them as a sequence of a response to stimulation.
