Abstract: Texts including required message are entered with a small number of keys such as those of a cellular telephone. In this case, a conversion table is unnecessary and the number of key operations is reduced. The number of input characters or input character strings composed by sequentially selecting one from a plurality of alphabets distributed to sequentially entered keys is relevant to the number of operation keys (N) raised to the number of distributed character (M) power (=NM) including meaningless characters or character strings and, with respect to these, character conversion is executed by referring to a dictionary means, through the operation of the conversion/next candidate key. The dictionary means stores numeric strings and words of meaningful characters or character strings among the said characters and character strings.

The number of input characters or input character strings composed by sequentially selecting one from a plurality of alphabets distributed to sequentially entered keys is relevant to the number of operation keys (N) raised to the number of distributed character (M) power (−NM) including meaningless characters or character strings and, with respect to these, character conversion is executed by referring to a dictionary means, through the operation of the conversion/next candidate key.

Abstract: The present invention concerns a coordinate input device for entering coordinate values by superposing on a display device (LCD or CRT). The device is comprised of a coordinate input section wherein a first conductive sheet for x-coordinate detection provided with electrodes on a pair of end edges and a second conductive sheet for y-coordinate detection provided with electrodes on a pair of end edges are superposed through a spacer so that respective electrodes intersect orthogonally. In a low power consumption mode of operation; a predetermined voltage is applied between one of the electrodes of the first conductive sheet and one of electrodes of the second conductive sheet for detecting a variation of the voltage. When the voltage varies the device switches, a predetermined voltage is applied between one electrode x1 of the first conductive sheet and one electrode y2 of the second conductive sheet.

Abstract: A thermal head comprises a plurality of parallelogrammatic resistors for generating heat formed on an insulated substrate made of, such as ceramics or alumina. The resistors are aligned at regular intervals, and one pair of opposite sides of each resistor are connected individually to lead electrodes. These opposite sides are equal to or longer than the other opposite sides, and an acute angle formed between each two intersecting sides is 45.degree. or less. The resistor is heated by various electric currents to record printing dots of various sizes.

Abstract: A thermal head is used on a thermal transfer recording apparatus which can record a continuous, fine line or curve by recording many dots, by a thermal transfer system, on a recording sheet. The thermal head comprises a one-dimensional array of heat generation element groups each comprised of a plurality of heat generation elements, such as heat generation resistors of, for example, a parallelogram, a diamond or an elliptic configuration, continuously arranged in a direction perpendicular to that in which recording is made on a recording sheet and lead electrodes connected adjacent to each other in predetermined positions, in which the longitudinal sides of the heat generation resistors are made oblique at a predetermined angle.

Abstract: In a communication system which is arranged to circulate an addressed electronic document among a plurality of terminals which are connected to one another through a transfer path and to sequentially add attest patterns indicative of the approvals of individual reviewing persons to the electronic document, a method for identifying the source of each person's approval symbol and amendments to the document. The data structure of each electronic document communicated between individual terminals is assembled in a data structure which separates the document content data from the attest patterns added to the document by the creating or reviewing person. If any reviewing person requests to amend the contents of the electronic document to which the attest patterns have been added, a display of only the content data of the above electronic document is presented to the reviewing person.

Abstract: A data processing system including a display unit for displaying a plurality of graphic patterns and names thereof corresponding to resources, and an input unit for selectively designating objects to be processed from graphic patterns or names being displayed. A file is provided for registering the graphic patterns and names corresponding to the resources in connection with each user. The graphic patterns and the names thereof specific to a user are read out from the file on the basis of user identifying information inputted in precedence to the data processing and this read out data is displayed on the display unit.
