An optical communication system includes a single master machine, a plurality of slave machines, and an optical adapter for optically communicating between the master machine and the slave machines. The optical adapter comprises a receiving unit, an amplifier, and an optical projector consisting of a concave mirror. The receiving unit receives optical information from either the master machine or the slave machines. The amplifier means amplifies the optical information. The concave mirror reflects or propagates the optical information of the master machine or the slave machines toward the slave machines or the master machine, respectively.

Optical communication adapter with projector

An electronic apparatus includes power source for supplying a power, key input unit for inputting key instructions, a memory for memorizing the key instructions, a generator for generating a power off cancel instruction to be invalidated the power-off of the power supplied from the power source in response to at least one of the key instructions or at least one of the memorized instructions memorized by the memory, a detector for detecting the output of the power off cancel instruction generator, and a controller for controlling the power source in response to the output of the detector.

Method for generating instructions for inhibition switch-off of power

In a language translator with a speech synthesizer, fixed words and variable words messages with translation are selectable.

A synthetic-speech calculator includes a calculating circuit inclusive of a plurality of memory locations to allow successive or chain calculations by some calculations equations and calculating numerical data, and voice synthesizer for providing pronunciation of selected calculating information. The calculator further comprises a first circuit for loading the some calculation equations and the calculating numerical data to the selected memory locations, a second circuit for indicating or pronouncing the some calculation equations and the calculating numerical data which have been utilized for the calculation and stored in the memory locations, and a third circuit for repeating the calculation by the some calculation equations and the calculating numerical data all stored in the memory locations.

Playback operation circuit in synthetic-speech calculator

A card-type compact data terminal is provided being operatively connectable to a portable electronic apparatus. The data terminal can be removed from the apparatus. The data terminal serves to input and store data for the apparatus while separated from the apparatus. When it is operatively combined with the apparatus, the stored data within the data terminal are processed by the apparatus, even complicated processes, at high speed.

Card-type data terminal operatively connectable to electronic apparatus

In a talking alarm clock, coincidence of real-time and preset alarm-time causes output of a fixed-plus-variable word message. Fixed words are stored in a ROM, while variable words are entered and stored in a circulating analog semiconductor memory.

A wireless phone system comprises a master phone unit connectable to a telephoneline, and a wireless phone receiver connectable to the master phone unit, the wireless phone receiver comprising a computer circuit for processing data as a computer, a wireless circuit for wirelessly transmitting information including the computer data, microphone means for inputting sound information, speaker means for outputing the sound information, and switching means for selecting whether the microphone means and the speaker means are connected with the computer circuit, or not. The master phone unit has a computer circuit.

Wireless phone system communicatively combined with a computer

In an electronic apparatus, for example, a programmable calculator, a portable or handheld computer, a memory module, or a data collector, incorporating a battery backup RAM, the present invention provides means for first checking the memory contents when the power-OFF command has been activated, and then causes the results of the checking to be stored in a specific area of the RAM. When the memory contents checking command has been activated, the system rechecks the memory contents to see if the memory contents have varied. The invention securely confirms whether the memory contents of either the effective programs or data have been correctly backed up when either replacing the battery or during storage of an electronic apparatus that uses the battery backup RAM. This is particularly effective for portable or handheld programmable computers.

Memory contents confirmation

An electronic bookkeeping device is useful in association with use of credit cards for controlling use of various credit cards. The device stores data relative to the extent of use of each card, and assists a user in making the most effective use of a plurality of credit cards.

Information processing device

A speech synthesizer may generate random sounds during die-down after power turn-off. To prevent such sound generation, the synthesizer clock circuit is grounded by an FET simultaneously with power turn-off.

Noise reduction circuit of synthetic speech generating apparatus

An electronic translator is disclosed wherein a first word or words represented in a first language are entered to obtain a second word or words represented in a second language equivalent to the first word or words. The translator comprises an input circuit for entering the first word or words, a memory circuit for storing the second word or words, an access circuit for addressing the memory to cause retrieval of the second word or words, a retrieval control circuit for selecting the retrieval speed of the access means and an indicating circuit responsive to the access circuit for indicating the second word or words.

Variable retrieval speed/direction electronic translator

An alarm timepiece is disclosed which is capable of setting a plurality of alarm settings and selecting which of a plurality of messages should be outputted in association with a respective alarm setting. Selected messages are output by a speech synthesis technique, and an exchangeable ROM cassette is provided for containing speech-synthesizing data characteristic of the content of the messages.

Speech synthesizer timepiece with alarm function

A new and useful combination of a radio receiver, a television receiver, a tape recorder and an electronic calculator is described. A display (for example, a cathode ray tube) of the television receiver is connected to serve also as a display for the electronic calculator. Data may be introduced into the calculator via the tape recorder and recorded into the tape recorder. The television receiver serves a display and the tape recorder serves as an external storage, with respect to the calculator.
