Patent number: 5604853Abstract: A text managing system performs an editing operation of a text using a text editing program in a computer system. The system includes a text operation unit which receives insertion/update/deletion information of the text input by an operator and displays the result of the editing for the above information on a screen. An UNDO/REDO control unit restores the text to be displayed on the screen for the previous states as to the result of the editing and reexecuting the text restored based on the above steps. An UNDO management table stores UNDO levels indicating the number of the UNDO operation. An UNDO management block manages the text edited in the above steps by pointing from the UNDO management table during the editing operation. An UNDO text block holds an insertion text into be inserted to the text, an update text to be updated from the text, and a deletion text to be deleted from the text during the editing operation. A text processing unit for manages the text already edited in the editing operation.Type: GrantFiled: May 18, 1992Date of Patent: February 18, 1997Assignee: Fujitsu LimitedInventor: Hironobu Nagashima

Patent number: 5157606Abstract: A multi-language conversion system is provided having a multi-language conversion table with a plurality of sub-tables for individual languages. These sub-tables include a keyword module for managing a keyword to be subject to a conversion in a predetermined sequence and a data module for storing translated data corresponding to the keyword in accordance with the order of the keywords and for storing default data. A multi-language conversion table selection unit selects at least one of the multiple language conversion sub-tables in accordance with a language conversion designation. A multi-language conversion module unit determines whether the language data subject to conversion exists in the keyword module, determines the translated data as a conversion data when the language data subject to conversion exists in the keyword module and determine default data as the conversion data when the language data subject to conversion does not exist in the keyword module.Type: GrantFiled: March 13, 1990Date of Patent: October 20, 1992Assignee: Fujitsu LimitedInventor: Hironobu Nagashima

Patent number: 4783787Abstract: A laser beam generating device that can vary its output by mechanical means. The laser output can selectively be chopped by selectively moving a chopping wheel into the path of the laser beam, whereby full power is obtained without the chopper and reduced power is obtained with the chopper.Type: GrantFiled: June 5, 1986Date of Patent: November 8, 1988Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Yuzuru Doi, Hironobu Nagashima

Patent number: 4704677Abstract: An output control device for controlling the output of an electrical apparatus such as a laser in which a desired accuracy of control is maintained irrespective of the magnitude of the target value of the output. A first multiplication circuit multiplies the output indicating signal by a value which is dependent upon the reciprocal of the target value. The output of the first multiplication circuit is compared with a predetermined reference value to form a feedback signal having a component applied to control the output in such a manner that the absolute value of the difference between the output of the first multiplication circuit and the reference value tends to be decreased. A second multiplication circuit multiplies the comparison value output by the reciprocal of the output of the first multiplication circuit, and the resulting signal is applied to control the output of the electrical apparatus.Type: GrantFiled: May 6, 1986Date of Patent: November 3, 1987Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hironobu Nagashima, Noriyuki Asai

Patent number: 4616636Abstract: A light emission switching circuit for use in a larynx stroboscope in which switching between a mode in which a stroboscopic lamp is flashed in synchronism with vibration of vocal cords and a mode in which the lamp is flashed at a fixed frequency is effected quickly in such a manner that there is no gap in light output at the time of switching. A detection output signal is produced when the frequency of a vocal cords vibration signal falls below a predetermined frequency, typically, about 50 Hz. When this signal is present, a switch circuit is controlled so as to connect the output of a fixed-frequency oscillator to drive the stroboscope. When the signal is absent, a pulse signal synchronous with the vocal cords vibration signal is employed to drive the stroboscopic lamp.Type: GrantFiled: July 18, 1985Date of Patent: October 14, 1986Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hironobu Nagashima, Hiroshi Koyama

Patent number: 4378492Abstract: A laser output measuring device for a laser knife having a flexible manipulator in which the output power at the operating end of the manipulator is accurately displayed at all times independent of changes in the transmissivity of the manipulator. A measuring hole member is provided in a housing in which is positioned a laser oscillator, a shutter device and a power detecting device. When the end of the manipulator is inserted in the measuring hole member, the shutter is positioned such that the output laser beam is directed onto the power detecting unit while when the end of the manipulator is free, the position of the shutter is determined by a foot switch such that the output laser beam from the laser oscillator can either be directed into the manipulator or to the power detecting unit.Type: GrantFiled: February 12, 1981Date of Patent: March 29, 1983Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hironobu Nagashima, Teruo Sakai, Yuzo Noguchi, Kiyoshi Itoh

Patent number: 4273959Abstract: A stroboscope device for diagnosis of larynx emissions. The system uses a saw tooth wave for generating in synchronization with a vocal cord vibration saw tooth waves whose voltages are constant in minimum and maximum values. A reference voltage generating circuit is used whose output voltage is variable and a discharge tube light emission control signal generating circuit compares the instantaneous voltage of each saw tooth wave with the output of the reference voltage generating circuit to generate a discharge tube light emission control signal in a phase shift range with respect to said vocal cord vibration. The discharge tube light emission control signal may be generated in a desired phase of said vocal cord vibration every period of said vocal cord vibration or at a repetition rate of multiple periods of the vocal cord vibration.Type: GrantFiled: November 14, 1978Date of Patent: June 16, 1981Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Koji Tuda, Hironobu Nagashima, Masatoshi Marui

Patent number: 4232685Abstract: A larynx stroboscope device capable of photography following the anode or cathode terminal of a flash discharge tube is connected to a photographing charge-discharge capacitor by the release operation of a camera. A trigger pulse is applied to the trigger terminal of the flash discharge tube in synchronization with a vocal cord vibration signal so that the flash discharge tube emits light while the shutter of said camera is open. Upon completion of a photographing operation, all the functions are automatically restored to the states obtained before the release operation. Alternatively, a charge-discharge system may be used. By the release operation of a camera supply of charging current to said capacitor is suspended. Thereafter a trigger pulse is applied to the trigger terminal of said flash discharge tube in synchronization with a vocal cord vibration frequency so that said flash discharge tube emits light while the shutter of said camera is open.Type: GrantFiled: November 14, 1978Date of Patent: November 11, 1980Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hironobu Nagashima, Koji Tuda, Masatoshi Marui

Patent number: 4222394Abstract: A device for processing a waveform for a larynx stroboscope having a plurality of filters receiving a vocal cord vibration signal. The outputs of the plurality of filters are automatically switched over by subjecting the outputs of the plurality of filters to comparision with one another to detect the fundamental wave component of the vocal cord vibration signal.Type: GrantFiled: November 13, 1978Date of Patent: September 16, 1980Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Hironobu Nagashima, Koji Tuda, Masatoshi Marui
