Abstract: In an automatic telephone answering system which records and reproduces an outgoing message to be sent to a calling party and an incoming message from the calling party on a recording medium, such as magnetic tape, a single-tone test signal from a touch tone signal generator is recorded on the tape as a cue signal to indicate a position of one of the incoming and outgoing messages. The single-tone signal is also used for a variety of signals in the operation of the automatic telephone answering system, such as a beep tone, an instruction signal and an alarm signal. The reproduced cue signal which is within an audio band is discriminated from an audio signal representing the outgoing or incoming message by a phase-locked loop having a narrow capture range and a loop filter with a prolonged time constant.

Abstract: The invention discloses a telephone set and a method for its operation for storing a message and a telephone number of each telephone set to which a message is transferred, and reading out the telephone number to perform dialing for the destination telephone set. If a continuous period of silence is sent back from the destination telephone set for a predetermined time interval within a larger predetermined time interval after the connection is established, the telephone set reproduces the recorded message and sends it over the telephone lines to the destination set, otherwise the telephone set disconnects from the telephone line. The operation is automatically repeated for each designated destination telephone set, thereby automatically transferring the same message to a plurality of destination telephone sets.

Abstract: An AlGaInP-based semiconductor light-emitting device is of a real-guide type and has excellent crystallinity and excellent laser characteristics. In an AlGaInP-based semiconductor light-emitting device having at least a first conductivity-type first cladding layer (3), an active layer (4) and a second conductivity-type second cladding layer (5), a stripe-shaped ridge (8) is formed on the second cladding layer (5) and first conductivity-type AlGaAs current confinement layers (19) with a band gap larger than that of the active layer (4) and whose refractive index is smaller than that of the active layer are formed so as to bury grooves (7) formed at both sides of the stripe-shaped ridge (8).

Abstract: A semiconductor laser is formed into a double hereto junction structure comprising an n-type cladding layer (3) and a p-type cladding layer (5) with an active layer (4) interposed therebetween. The p-type cladding layer (5) has a laminated structure consisting of a first cladding layer (51) of (AlxGa1-x)InP disposed on one side adjacent to the active layer (4) and a second cladding layer (52) of AlyGa1-yAs disposed on the reverse side. A deterioration preventive layer (11) of AlzGa1-yAs is included in the first cladding layer (51) at a position spaced apart from the second cladding layer (52) by a predetermined distance. In addition, the second cladding layer (52) is partially removed, and a current stricture layer (10) is formed in such removed portion.

Abstract: SO3162 PATENT A first recording medium of automatic telephone answering apparatus records an OGM (Outgoing Message) and a second recording medium records ICMs (Incoming Messages). Immediately after the first ICM is recorded, a first muting portion and a first cue signal (control signal) are sequentially recorded on the second recording medium. Then, the second recording medium is rewound to a position intermediate the length of the first cue signal and the automatic answering mode is reset. Before recording of the second ICM, a second muting portion of a predetermined duration is recorded on the second recording medium, so as to modify the first cue signal to form a second cue signal shorter than the first cue signal. The second ICM is then recorded on the second recording medium. This process is repeated for subsequent ICMs so that a short (second) cue signal marks the separation between each pair of successive ICMs and a long (first) cue signal marks the end of all the ICMs.

Abstract: A telephone set (1) stores a message and a telephone number of each telephone set (2 to 4) to which the message is to be transferred, and reads out the telephone number to perform dialling for the destination telephone set (2 to 4). If no voice signal is sent back from the destination telephone set (2 to 4) within a predetermined time interval after the connection is established, the telephone set (1) reproduces the recorded message and sends it over the telephone lines to the destination set (2 to 4). The operation is automatically repeated for each designated destination telephone set (2 to 4), thereby automatically transferring the same message to a plurality of destination telephone sets (2 to 4). … …

Abstract: This invention relates to an automatic telephone answering apparatus which has a record/play head, a play means, a record means, a fast forward means, a rewind means, a detecting means for detecting a remote control signal supplied through telephone lines, and a tape position detecting means. When the remote control signal is detected during playback of an outgoing message prerecorded on the tape, the tape is fast forwarded to a predetermined position, and the apparatus is set in the play mode. During playback, when the remote control signal is detected, the tape is rewound to the beginning of the outgoing message, and the apparatus is set in the record mode to record a new outgoing message. After the new outgoing message is recorded to the predetermined position, the tape is rewound to the beginning of the outgoing message, and the apparatus is set in the play mode. During playback, when the remote control signal is detected, the corresponding tape position is detected, thereby preventing the remote control signal from being recorded at the end of the new outgoing message.
