Abstract: An electronic dictionary comprising an input device, a display, a dictionary memory, a searching device, and an indicator device. The memory consists of plural divisions of equal storage capacity and stores multiple sets of word data representative of different words in an alphabetical order. Each set of word data is stored in one of the plural divisions such that each of the divisions has at its end a waste portion storing no part of any of the multiple sets of word data, if the number of characters of the first set of word data stored in the following division is larger than the number of characters which may be stored in the waste portion.

Abstract: The system includes a dictionary memory for storing a plurality of English words which are classified into two groups consisting of noun words and non-noun words, respectively; search circuitry for searching whether or not an inputted word exists in the dictionary memory; and suffix judgment circuitry for judging whether or not an inputted word has a possessive suffix. If the inputted word has one of the possessive suffixes, the group of noun words in the dictionary memory is searched to find the coincident word data to the de-suffixed input word. An output display displays the input word and the search result.

Abstract: A system for checking a spelling of an English word which stores a plurality of English words in several groups. Every word in each group can have a common suffix and is stored without the suffix. The system searches whether or not an input word exists in the dictionary memory and judges next whether or not an input word has one of the suffixes by which the words in the dictionary memory are classified. If the input word has one of the suffixes, the system searches a de-suffixed form of the input word within the group corresponding to the suffix. The search result and input words are displayed on a cathode ray tube.

Abstract: An electronic dictionary comprising a dictionary memory having multiple data memory locations identified by respective addresses. Each of the data memory locations comprising a word-data memory location which stores word data representative of a word of a language. The word data in each one of the data memory locations comprising at least one character code each representing one of letters of the word, and/or at least one special code each representing a combination of at least two adjacent ones of said letters of the word which are idential with corresponding adjacent letters of the word represented by the word data in another of the data memory locations which is adjacent to the above each one data memory location. The dictionary further comprises a control unit which retrieves the word data corresponding to a keyed-in word and converts the special code, if any in the retrieved word data, into plural character codes which represent the letters represented by the special code.

Abstract: An apparatus for checking a spelling of an input English word and for storing a new English word is provided, including an input device for receiving a word, an electronic dictionary memory consisting essentially of a first dictionary in which pre-installed English words are stored and a second dictionary for storing new English words and a search device for searching an input word through the first and the second dictionary. A store is also provided for storing a new input word that has not been found in either the first or the second dictionary into the second dictionary which includes an address memory in which an address of the second dictionary for starting the word searching is stored. A writing device is provided for writing the new input word at just before the address stored in the address memory, and a change is provided for changing the address in the address memory to the head address of the written word.

Abstract: An electronic dictionary in which a plurality of word data each representing an English word are stored in a predetermined order and each word data comprises a data division and an additional division. Each data division includes a combination of one or more parts among a first compressed part, a second compressed part and a third compressed part; the first compressed part being a code indicating the number of first characters that are common between an English word represented by the corresponding word data and the English word whose corresponding word data is stored just before the word data in the electronic dictionary; the second compressed part being a code indicating a suffix which appears in English words, and the third compressed part being a sequence of codes each representing each alphanumerical character not represented by a first or second part code.

Abstract: An electronic dictionary comprising a dictionary memory having multiple memory locations each of which comprises a vocabulary-data memory location and an address-number memory location corresponding to each other. The vocabulary-data memory locations store vocabulary data representative of different vocabulary entries including plural groups of entries, each group consisting of the entries of the same nature which include at least one special entry. The vocabulary entries of each group are retrieved in a predetermined order. Each of the address-number memory locations corresponding to the entries of each group except the special entry stores address-number data representative of an address of the vocabulary data which is retrieved next, whereby the entries of each group are successively retrieved. Special data is stored in the address-number memory location corresponding to the vocabulary-data memory location which stores the special entry.

Abstract: An electronic dictionary comprising a dictionary memory which has multiple data memory locations identified by respective addresses. Each data memory location comprises a word-data memory location for storing a word, and an address-number memory location for storing one of the addresses at which is stored a word synonymous with or antonymous to the word stored in the corresponding word-data memory location. Upon entry of a word through an input device, the word stored in the dictionary memory is retrieved from the respective word-data memory location, and the address-number data in the corresponding address-number memory location is read out to search the data memory location which is designated by the read-out address-number data. The word stored in the word-data memory location of the searched data memory location is displayed as a synonym or antonym of the word which has been entered through the input device.

Abstract: A sewing machine aurally informs an operator of abnormal conditions which accidentally have taken, or are taking, place by means of a vocal indication. One group of speech data corresponding to an accidentally occurring abnormal condition is selected from among plural groups of speech data according to a detection signal from a plurality of abnormal condition detectors disposed in the machine. A voice signal corresponding to the selected group of speech data is generated in relation to operation of a manual device e.g. a button such as a switch, for the start of sewing. The operator can hear the warning voice due to this vocal indication simultaneously with the operation of the manual button for the start, whereby he/she is prevented from starting of the machine while the abnormal condition exists.

Abstract: An electronic typewriter comprising: a keyboard having a plurality of keys and generating an encoded signal in response to the depression of each key; a printing unit having a print wheel with a plurality of type elements disposed around the periphery thereof, a step motor for rotating the print wheel, a print hammer for impacting the type element brought to a printing position, an ink ribbon, and a ribbon drive mechanism for bringing the ink ribbon to the printing position; and an electronic control circuit for coupling the keyboard to the printing unit. The electronic control circuit controls the rotation of the step motor according to the encoded signal received from the keyboard so as to bring a type element selected by the encoded signal to the printing position within a short time for executing quicker printing, and further controls the action of both the print hammer and the ribbon drive mechanism in response to the rotation of the step motor.
