IPC: G09F9/00
Filed: 1985-09-30
Abstract: PURPOSE:To directly record, display, hold, and rewrite information and to eliminate the need for power consumption as less as possible through all these functions by impressing voltage to the surface of light transmissive porcelain having an electro-optical effect and receiving distortion in one direction with a voltage impressing head. CONSTITUTION:A component consisting of lead titanate/zirconate (PLZT) include lanthanum and expressing a large Kerr effect is used and the voltage impressing head 2 for partially impressing voltage is formed on the surface of a PLZT plate 1. When distortion is applied to the PLZT plate 1 in one direction by clamping a screw 7, double refraction is generated by the optical elasticity of the PLZT and light is reflected. Thereby, a voltage is impressed to an optical part of the PLZT plate 1 with the voltage impressing head to display and image. Since scanning is executed by the voltage impressing head, the voltage impressed part on the PLZT plate 1 stores electrostatic charge due to the impressed voltage and keeps recording state.

IPC: H04B10/40
Filed: 1987-08-31
Abstract: PURPOSE:To discriminate the content of logic level independently of an offset voltage of a reception signal, by giving respectively an integration processing signal of a reception signal to a 1st comparison input terminal and a feedback signal to its own comparison output reception signal to a 2nd comparison input terminal so as to apply level comparison of the input signals. CONSTITUTION:By the input of a reception signal S1, a signal S2 fed to an inverting input of the comparator 13 via an integration circuit 12 becomes the signal of the mode as shown in figure (b) by the repetition of charge/ discharge based on the integration time constant of the signal S1. Then a comparison output S4 by other comparator 13 is fed back positively to the signal S1 and the signal S3 fed to the noninverting input of the comparator 13 is the signal of the mode as shown in figure (c). Thus, a signal representing ground level or power voltage Vcc level in the mode as shown in figure (d) is outputted corresponding to the content of the logic level of the reception signal S1 as the comparison output S4 between the signals S2 and S3.

IPC: G06F17/22
Filed: 1983-11-19
Abstract: PURPOSE:To limit the learning processing frequencies and to prevent the reduction of an input speed by performing the learning process to the homonyms immediately after conversion of KANJI (Chinese character). CONSTITUTION:A read string supplied from an input means 1 is converted into KANJI and phrases by a converting means 2, and the candidate KANJI for conversion (candidate words) are delivered to an output means 3. If the delivered KANJI (the 1st candidate word) is not equal to the desired KANJI and phrase, the next candidate word is converted by a next candidate indicating means 4 and the means 2 and delivered to an output means. When the delivered candidate word is coincident with the desired KANJI, etc., the selection is indicated by a homonym selecting means 5. Then the candidate words delivered presently to the means 3 are selected. In this case, it is decided whether the selected KANJI is equal to the one obtained immediately after the KANJI(Japanese syllabary)/KANJI conversion. If the selected KANJI is equal to the one obtained immediately after said conversion, the using frequency information or the using order information on a dictionary 7 is replaced by a learning means 6. Thus the learning process is performed to the homonyms immediately after the KANA/KANJI conversion. Therefore the input speed is never limited and the input efficiency is improved with the learning processing.
