Abstract: An information storage medium according to the present invention is adapted for multiple different writing speeds and stores in advance writing conditions associated with each of the multiple writing speeds. The writing conditions include: a recording-power-related parameter and a write-waveform-related parameter, which are associated with each particular writing speed to perform a write operation at the particular writing speed; and another recording-power-related parameter for performing a write operation at a different writing speed other than the particular one using the recording-power-related parameter for performing the write operation at the particular writing speed.

Abstract: A cordless telephone having a base unit to be connected to a telephone line network and a handset unit to be connected to the base unit through a communication channel upon initiation of a telephone conversation. The cordless telephone includes a detecting circuit provided in the handset unit for detecting removal of the handset unit from a predetermined standby position, and a circuit for generating a command signal such that, when the detection output of the detecting circuit indicates that the handset unit is picked up from the predetermined standby position and, on the condition that a dial key of the handset unit is operated, the base unit is connected to the telephone line network.

Abstract: A cordless telephone is comprised of a base unit, a handset unit, and a telephone answering machine (TAM) unit. In a normal communication mode, audio signals from the handset unit are coupled to the telephone line network through the base unit. In an automatic answering mode, an audio signal from the telephone line network is recorded at the TAM unit through the base unit. When a predetermined key of the handset unit is operated, a control signal is supplied to the TAM unit by way of a transmitting circuit in the handset unit, a receiving circuit in the base unit, a transmitting circuit in the base unit and a receiving circuit of the TAM unit to place the TAM unit in a reproduction mode, whereby previously recorded audio signals are reproduced and supplied to the handset unit via a transmitting circuit in the TAM unit, the receiving circuit in the base unit, the transmitting circuit in the base unit and a receiving circuit in the handset unit.

Abstract: In a telephone apparatus used for a telephone system such that the telephone set is connected to a remote destination telephone set through telephone circuits after an ID number of a subscriber has been transmitted to the telephone company, the handset comprises a key entry section including plural dial keys, a memory section for storing the ID number and destination telephone numbers, a display section for displaying a destination telephone number corresponding to an operated dial key, and a control section for enabling a display of the ID number when the ID number is written but disabling a display of the ID number when read. Since the ID number is not displayed while being read to transmit it to the telephone company, the ID number of the subscriber is kept secret from others.

Abstract: An electronic apparatus includes a plurality of selectively actuable selection devices for causing the apparatus to perform a plurality of distinct operations. A first actuation of a selection device establishes a first condition to cause the apparatus to generate an externally detectable identification such as by voice synthesis of the selected operation, and a second actuation of the selection device establishes a second condition to cause the apparatus to perform the selected operation and identify the operation on a display. In a preferred embodiment, the selection devices are each a push button actuable from a rest position to a first depressed position to establish the first condition by actuating a first switch, and thereafter actuable from the first depressed position to a second depressed position to establish the second condition by actuating a second switch.
