摘要:
A radio telephone system having a charger separated from a base unit and connectable to a radio telephone to provide power thereto, and a recording and reproducing circuit separated from the radio telephone and the base unit to record and reproduce a voice signal. The voice signal representing a telephone call from the subscriber line is transmitted from the base unit via the charger to the recording and reproducing circuit for the voice signal to be recorded therein. The recorded voice signal can be reproduced and played through a speaker in places detached from the base unit. The radio telephone system includes a mode selector to set the system either in an automatic answering mode or a reproduction mode. Even when the battery power of the radio telephone runs out, the recording and reproducing circuit can still reproduce the recorded voice signal where an alternating current power outlet is available for the charger to provide power to the recording and reproducing circuit.
摘要:
A radio telephone apparatus comprising a main station connected to a wire telephone line and having a subsidiary telephone set, and a radio telephone set connected with the main station via a radio link, wherein the radio telephone set effectively or ineffectively controls a function of releasing the hold state by the off-hook operation of the subsidiary telephone set. By the operation of the radio telephone set, telephone communication can be switched between a self-hold state and a complete hold state. The self-hold state can be released only by the radio telephone set while the complete state hold can be released by any one of the radio telephone set and the subsidiary telephone set. In the complete hold state, the radio link between the main station and the radio telephone set is disconnected. If the complete hold state is released by the radio telephone set, the radio link is again established between the main station and the radio telephone set.

摘要:
A method and apparatus for controlling a radio telephone system of the type wherein a connection between a wired telephone channel and a plurality of radio telephone handsets is controlled by a single base station connected to the wired telephone channel, a ring signal through the wired telephone channel is detected, a paging signal is sent to the radio telephone handsets from the base station when the ring signal is detected and a paging response signal is sent to the base station from the radio telephone handset in response to the paging signal. Further a channel designating signal is sent to the radio telephone handset in accordance with the paging response signal, a radio channel of the base station is switched to a radio channel corresponding to the channel designating signal, the radio channel of the radio telephone handset is switched to a radio channel corresponding to the channel designating signal, and a speech channel is established between a radio telephone handset responding to the paging signal and the wired telephone channel.

摘要:
A portable unit that may be called from a base station through a radio control channel by a succession of terminating call signals that is sent through the control channel from the base station to the portable unit for a first or restricted time duration (T.sub.1), selected in consideration of a battery saving period of a battery saving operation carried out in the portable unit. Within the battery saving period, the portable unit is put into transient active and inactive states during a first time interval and a second time interval, respectively. Selection is made so that the first time duration is longer than the second time interval to receive at least one of the terminating call signals within the first time duration in the portable unit. The base station monitors an acknowledgement signal for a second time duration (T.sub.2) after the lapse of the first time duration and interrupts the control channel when the acknowledgement signal is not received within the first and the second time durations. In the portable unit, the battery saving operation is released when the presence of the terminating call signals is detected by a squelch circuit.

摘要:
It is possible to commercially advantageously prepare 1-{1-[2-(7-methoxy-2,2-dimethyl-4-oxochroman-8-y)ethyl]piperidin-4-yl}-N-methyl-1H-indole-6-carboxamide by coupling (7-methoxy-2,2-dimethyl-4-oxochroman-8-yl)acetaldehyde, which is obtained by oxidizing 8-(2-hydroxyethyl)-7-methoxy-2,2-dimethylchroman-4-one, with N-methyl-1-(piperidin-4-yl)-1H-indole-6-carboxamide.
