Abstract:
If a call waiting signal is supplied to a telephone line during reception of a videotex information through a videotex center, a control unit responds to the calling signal to actuate call waiting equipment and an associated switching unit for transmitting the calling signal to a videotex line and displaying an alarm signal at the videotex receiver. When the user of the videotex changes over the switches of the switch box and places his telephone receiver off-hook, he can communicate with the incoming calling party.
Abstract:
According to conventional telephone call forwarding devices, after a party at a telephone set A calls a party at a set B, a set C calls set D to forward the call, and when set D responds to set C, an alternate loop is formed between A and D. In some of said conventional devices, even when a general calling party calls set C, set B can autodial set A whose telephone number was memorized. However, nothing else can happen if set A doesn't answer the call after automatic dialing. The present invention makes it possible to store a plurality of telephone numbers of telephone sets of calling parties, A, A-1, A-2, A-3 . . . and automatically and successively to dial the stored telephone numbers of A-1, A-2, A-3 . . . even when A doesn't answer the call, so that the highly practical effectiveness can be obtained.
Abstract:
A sheet cutter apparatus includes circuitry for detecting when the blades of the cutter are in an "open" position with their cutting edges separted from each other, and a timer that is initiated when the blades are first opened. If the blades remain open for an excessive period of time, determined by the timer, a warning alarm is generated to remind personnel to close the blades, so that no injuries to fingers, etc., will occur.
Abstract:
An automatic telephone answering/recording device that is capable of storing messages sent from unspecified callers in a digital form and enabling an owner of the device to listen to the stored message quickly. The caller's messages are recorded in separate channels. Thereafter, in response to a first remote control signal sent by the owner from a remote place, each of the messages is reproduced in the order of reception, channel by channel. At this time, upon elapse of a blank portion produced following each reproduced message, a subsequent message is reproduced. Simultaneously, in response to a second remote control signal, unnecessary messages are specified and erased, and necessary messages to be stored are transferred to locations at which the erased messages were stored.
Abstract:
An automatic telephone answering/recording apparatus and a method of operating the same are provided. The apparatus has three operation buttons consisting of an outgoing message tape operation button, an automatic telephone answering/recording aspparatus operation button, and an incoming message tape operation button. When the apparatus operation buton is depressed, the automatic telephone answering/recording apparatus is set in the answering/recording standby mode. An outgoing message tape can be set in the play, stop, rewind, or fast forward mode in accordance with the number of times of depressions of the outgoing message tape operation button. Similarly, an incoming message tape can be set in the play, stop, rewind, or fast forward mode in accordance with the number of times of depressions of the incoming message tape operation button. The apparatus button and the outgoing message tape button or the apparatus button and the incoming message tape button are simultaneously or sequentially depressed to set the apparatus in the record or erase mode.
Abstract:
A control system for use with telephone terminal equipment comprises a timer which generates a dummy control signal upon elapse of a preset period of time from the instant of time when operation of an automatic telephone answering apparatus starts. A dummy ringing signal generated in response to the dummy control signal is applied to the telephone terminal equipment connected through a relay to the public telephone circuit. Then, the terminal equipment responds to the dummy ringing signal to operate to be connected with the calling party side.
Abstract:
A remote control unit controls at least one additional device such as a facsimile system through a telephone answering device. The telephone answering device is engaged with telephone lines upon reception of a ringing signal, and an outgoing message and an instruction message are sent out. A calling party can record an incoming message in a recorder in the telephone answering device if desired. However, when the calling party wishes to drive an additional device, a remote control signal corresponding to the desired additional device is sent in accordance with the instruction message. Then, the desired additional device can be driven, and other data can be transmitted or received. If the calling party sends the wrong remote control signal and therefore drives the wrong additional device, the calling party can reset the wrong device and drive the correct device by sending the correct remote control code, without hanging up the telephone.
Abstract:
Pulse sounds from a measuring device (1) for measuring a radioactive concentration or the like are counted by a preset counter (2). When a count of the preset counter (2) exceeds a predetermined value, the automatic dial device (5-1, 5-2, 5-3) is started to call an owner or the like of a measuring/alarm apparatus. When the owner answers the telephone, an alarm sound is sent from an alarm sound generator (7) onto the telephone line. Output pulse sounds from the measuring device (1) are recorded in a recording device (11) for every predetermined time interval after the alarm sound is sent onto the telephone line. The recorded pulse sounds can be sent to a remote location in response to a remote control signal.
Abstract:
In an automatic telephone answering apparatus, an input signal sent through telephone lines is enveloped to derive pulses. The pulses are counted by a first counter. When a predetermined period of time has elapsed, a count of the first counter is compared with a reference value. When the count is larger than the reference value, the input signal is regarded as a speech signal, and the first and second counters are reset to count the pulses again. The above operation is repeated. When the count has not reached the reference value, the second counter is operated. When another predetermined period of time has elapsed, the count of the first counter is compared with the reference value, and this operation is repeated. When the count of the second counter reaches a given value, the automatic telephone answering apparatus is set in the standby mode.
Abstract:
In a remote control system of electric equipment, a remote control box which is to be incorporated with the electric equipment is adapted to the remote control adapter which accepts a telephone call and engages with the telephone line upon acceptance of a telephone call and receives many kinds of remote control signals through telephone line to control the remote box according to the tone decoder connected to microprocessing controlled switches.
