Title: Kanji converter in character data input device
Inventor: KANEKO AKIRA
IPC: G06F17/21
Filed: 1984-04-06
Abstract: PURPOSE:To input efficiently either a Korea sentence or a Japanese sentence by using a dictionary for Hungle-Kanji (Chinese character) conversion and Kana (Japanese syllabary)-Kanji conversion in common and having only to retrieve one dictionary both for Hungle or Kana inputs. CONSTITUTION:The dictionary 7 is used in common for Hungle-Kanji conversion and Kana-Kanji conversion and the index of conversion information used for the Hungle-Kanji conversion consists of initial voice/medium voice and end voice information. In inputting a Kanji by the Hungle-Kanji conversion, when a Hungle element is inputted sequentially from a keyboard 1, the data is fed to a control section 6. The control section 6 uses a table 6a as to the data so as to collate the initial/medium/end voice corresponding to the combination of the elements as to the said data and the result of collation is used as an index code so as to retrieve a Kanji corresponding to the dictionary 7. The retrieved Kanji data is fed to a display section 8 and a storage section 9 via the control section 9 and then displayed and stored. Thus, either the Hungle sentence or the Japanese sentence is inputted efficiently.

Title: Scanning circuit for display device
Inventor: HAYAMA HIROSHI
IPC: H01L29/762
Filed: 1991-03-07
Abstract: PURPOSE:To allow operation with a high-speed transfer clock by providing a signal delay circuit for which a charge transfer element formed of a thin-film semiconductor is used. CONSTITUTION:An SiO2 film is formed on an N type silicon film formed on a glass substrate and further, a gate electrode is formed of n type polysilicon and aluminum on the SiO2 film. An n<+> layer is formed at both ends of the one-dimensional CCD by ion implanation to form an input gate diode and output gate diode. The operating speed of the CCD depends on the drift speed of the transfer carrier to the electric field induced by the transfer clock and the diffusion speed by the density gradient of the transfer carrier. The signal delay circuit formed by using the CCD can, therefore, be operated at the transfer clock speed higher than the transfer clock speed of a shift register circuit formed by using TFTs having the min. size of about the same degree.
