  • Publication number: 20100302922
    Abstract: An information recording device (1) comprises recording means (102) for recording information on an information recording medium by irradiating the information recording medium (100) with a laser beam for recording (L), control means (103) for recording data for calibration on the information recording medium by using the laser beam for recording whose power is adjusted step-by-step, and detection means (107) for detecting a push-pull signal in the area in which the data for calibration is recorded for each time when the power is adjusted step-by-step. When the push-pull signal exceeds the predetermined range, the recording of the data for calibration ends and the most appropriate power of the laser beam for recording is determined according to the regenerated signal obtained by reading the data for calibration.

  • Patent number: 5155759
    Abstract: A control method for a cordless telephone system including a main apparatus connected to a telephone line and having a line control function, a plurality of stationary apparatuses connected to the main apparatus and each having a radio transmitter/receiver, and portable telephones capable of communicating with the stationary apparatuses through a radio channel. When the main apparatus receives a simultaneous calling request signal from one portable telephone through a given stationary apparatus, it transmits a simultaneous calling request signal to whichever of the other portable telephones are not in use through corresponding stationary apparatuses.

  • Patent number: 5136629
    Abstract: A radio communication system of a multi-channel access type in which an idle one of a plurality of radio channels is detected to perform transmission and reception of voice signals, data signals or the like. In the present system, in the case where a base unit receives an incoming call from a wired line, the base unit transmits to a plurality of radio terminal units a speech channel designation signal as well as a representative radio terminal designation signal specifying a representative radio terminal unit from the plurality of radio terminal units, and when receiving a channel switching completion signal from the representative radio terminal unit, the base unit transmits a signal for generation of ringing tones to the plurality of radio terminal units at the same time to cause the plurality of radio terminal units to generate the ringing tones at the same time.

  • Patent number: 5086451
    Abstract: Disclosed is a radio channel control method for a system including a main apparatus connected to a telephone line and having a channel control function, a plurality of stationary apparatuses connected to the main apparatus and each having a radio transmitter/receiver, and a portable telephone capable of communicating with the stationary apparatuses through a radio channel. In this method, the main apparatus designates each stationary apparatus in a main or sub state to control communication with the portable telephone and monitors a state signal including information of the main or sub state transmitted from each stationary apparatus. When the state signal from a given stationary apparatus does not coincide with a state of the given stationary apparatus designated by the main apparatus, the main apparatus transmits a state designation signal to the given stationary apparatus to coincide with the state designated by the main apparatus.

  • Patent number: 4962524
    Abstract: A cordless telephone having a base unit and a plurality of radio telephone sets. The base unit delivers a ringing signal from a telephone line to a radio telephone set which is in telephone communication with a remote subscriber coupled to the telephone network, and a receiving radio telephone set in accordance with a request for transfer by the transferring radio telephone set. If the receiving radio telephone set responds to the ringing signal and goes off-hook, the telephone communication is transferred to the receiving radio telephone set from the transferring radio telephone set. If the receiving radio telephone set does not respond or does not go off-hook, the transferring radio telephone set responds to the ringing signal and goes off-hook to carry on the telephone communication.
