Abstract: An electronic apparatus has a first memory storing therein a plurality of data comprising a first lingual words and a second lingual words corresponding respectively thereto, and a second memory for storing information to freely read out at least one of said plurality of data stored in the first memory. The apparatus further has means for reading out the information stored in the second memory and reading out, on the basis of the information read out, the second lingual word relating thereto from the first memory.

Abstract: This electronic apparatus has combined functions of an electronic calculator or the like and a television receiver, and is automatically shifted, at the start of the calculator function, to a vacant television channel for the display of calculator functions on the television screen and returned to the television receiving function at the end of the calculator function.

Abstract: The electronic instrument includes a memory for storing scheduled time and schedule details, a clock circuit producing time signals, a comparator producing a comparison signal in response to comparison and coincidence of the time signals from the clock circuit with the scheduled time, a discriminating memory with a storage of a signal for decision for and against clear of the scheduled time and details in the memory, and a control unit for discriminating, in response to the comparator producing the comparison signal, the storage of signal in the discriminating memory to control over clear and non-clear of the scheduled time and schedule details in the memory.

Abstract: An electronic device for displaying accent is disclosed which is useful for displaying words and sentences by use of a multiple-digit display device. In the respective word display parts of the multiple-digit display device, additional symbols for an accent display are provided. Alphabet characters can be expressed as five-bit codes. In one disclosed embodiment, an additional sixth bit is used to indicate the presence or absence of an accent associated with the character represented by the remaining five bits. In another disclosed embodiment, accented vowels are each represented by five-bit codes that are different from the five-bit codes representing the same vowels without accents, so that no sixth bit is necessary. Words are displayed while discriminating a word with accent from a word with no accent.

Abstract: An electronic apparatus is disclosed which comprises numeral input keys, plural unit input keys, a device for judging whether a combination of actuations of the numeral input keys and the unit input keys has a meaning as a figure, a device of forbidding the entry of the key signals of said combination in case said combination does not represent a meaning as a figure, and a device for generating an alarm signal simultaneously with the forbidding of said key signal entry.

Abstract: A memorandum calculator is disclosed for performing arithmetic calculations on entered numeral information and generating information relating to the calculation, for storing data items consisting of address information entered as memory addresses and numerical information associated with the address information, and means for effecting performance of the arithmetic operation with respect to the numerical stored information according to input instructions.

Abstract: An input device for electronic apparatus includes key signal output lines each having plural key switches connected thereto and circuitry for separating the key signals into specific key signals thereby identifying the plural key switches.

Abstract: The electronic apparatus is provided with a device for informing the operator of information on the service life of the battery employed for driving the electronic apparatus.

Abstract: An electronic calculator having a printer detects the key entry by one of arithmetic keys following the numerical key entry and prints one of arithmetic symbols and entered number respectively at the left-hand side and right-hand side of the print sheet.

Abstract: In an electronic equipment capable of statistic processing of the type wherein numeric data of a plurality of variables are entered in a predetermined sequence and then statistically processed (for instance, a numeric data X.sub.1 is entered first and then a numeric data Y.sub.1 is entered and thereafter the data X.sub.1 and Y.sub.1 are statistically processed. Thereafter, in like manner a numeric data X.sub.2 is entered and then Y.sub.2 is entered, and so on.), an arrangement whereby one may easily check a numeric data to be entered next; that is, whether a numeric data to be entered next is a data X.sub.n or Y.sub.n.

Abstract: In a numerical value input display, by an operating unit input device for entering the unit of a first entered numerical value, the numerical value being displayed on a display unit is taken up in a column corresponding to the unit and, at the same time, the columns less significant than that unit are rendered into a particular condition so that a second numerical value can be displayed at the position of that particular condition. The portion of the display unit rendered into the particular condition produces a display different from the display of the first numerical value or is made blank. The display is provided with a memory for storing the first entered numerical value and the unit of the first numerical value correspondingly to the columns or place in the display unit where it is to be displayed, and a particular code is displayed in the portion representing the unit stored in the memory so that a newly entered numerical value can be stored at the places of the particular code.

Abstract: An electronic apparatus comprises a phase signal generator for generating mutually different phase signals, one of which is selectively supplied to plurality means driven by a time-division drive.

Abstract: An electronic scheduler includes a comparator for comparing schedule information to be newly stored with schedule information already stored in the memory. Circuitry is provided for determining whether the output of comparison from the comparator falls within a predetermined range, and an alarming circuit for giving an alarm in response to the output present within said range.

Abstract: A display device for use in electronic calculators capable of displaying determinants. The display device is able to display data of positions in row and in column of elements in a determinant together with numbers associated with the elements. The data of positions in row and column is displayed as selective segments of a figure "8" pattern.
