Patent JP-H1092324-A (JP)
Title: Plasma display panel and splitting method thereof
Inventor: LEE EUN-CHEOL
IPC: H01J11/38
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To stably maintain electric discharge state of each cell, reduce data quantity which a driving circuit shares, and enable designing by ordinary elements by independently driving a split screen. SOLUTION: In the case of four-piece splitting, for example, a common electrode 103 of a transverse electrode and a scanning electrode 102 parallel thereto are split horizontally by a bulkhead 116, and a data electrode 101 of a vertical electrode is vertically split at a substantial center part. That is, the transverse electrode and an insulation film formed on a surface thereof are horizontally split into two sections by the bulkhead 116 and are vertically split into two sections similarly, and a total of four divisions are achieved. Thereby, in comparison with when a single driving circuit is driven, a period of maintenance pluses increases, and necessary time at the maintenance pulse period to be constantly discharged is reduced. Since there is much pixels on a large-sized screen, expensive high-speed elements such as gallium arsenide is necessary, however, regular flip-flop can be used by screen division, and a serial-parallel converting circuit can be achieved.

Title: Telephone set
Inventor: NAGATANI MAMORU
IPC: G10L13/04
Filed: 1987-09-22
Abstract: PURPOSE:To evade misunderstanding due to missing of storage at reproduction, for example, by storing a voiced part of a voice signal without missing of speech head and tail in storing the received voice signal so as to store the voice signal without missing. CONSTITUTION:When an input voice signal goes to a voiced signal from a silent signal, a voice detection circuit 2 detects the change from the silence into the voiced sound, sends a control signal to a recording circuit 3 to start recording. The voice delay circuit 1 outputs a delay voice signal retarding the voice signal by a delay time T and the recording circuit 3 receiving the control signal starts the recording of the delayed voice signal within the delay time T. When the input voice signal becomes the voiced signal from the silent signal, the voice detection circuit 2 detects the change of the voiced sound into the silence and sends a control signal to stop the recording to the recording circuit 3. The recording circuit 3 stops the recording of the delay voice signal after the delay time T after receiving the control signal. Thus, the input voice signal is sound-recorded and reproduced by the recording circuit 3 without missing of speech head and tail.

Title: Integrated circuit with latch-up protecting circuit
Inventor: YOOZEFU UINNERURU
IPC: G05F3/20
Filed: 1987-09-22
Abstract: A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted. In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the substrate depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal. The electronic protection circuit connects a capacitor bias generator to the capacitor when a voltage on the substrate bias terminal is less than a sum of a reference potential and a threshold voltage of a first transistor in the electronic protection circuit. The electronic protection circuit disconnects the capacitive bias generator from the capacitor when a voltage on the substrate bias terminal is greater than the sum. During normal operation the electronic protection circuit does not load a supply voltage source or a substrate bias voltage source with current.

Title: Manufacture of three-dimensional optical circuit element
Inventor: KAGAMI MANABU
IPC: H01L21/265
Filed: 1987-09-25
Abstract: PURPOSE:To reduce the man-hours and manufacturing time required for the manufacture by drawing a three-dimensional waveguide on a substrate with a convergent ion beam which is generated by using a rare earth element as an ion seed. CONSTITUTION:The rare earth element is vaporized by being heated, then ionized, and further converged by a lens using an electric field or magnetic field to generate the converged ion beam 1 of rare earth ions. This converged ion beam 1 is deflected by the electric or magnetic field to implant rare earth ions in the surface layer of the substrate 3 in a desired pattern and the ion- implanted part of the substrate is reformed to vary in refractive index in three dimensions, thereby forming an optical waveguide 2. Thus, the three-dimensional waveguide 2 is drawn with the converged ion beam generated by using the rare earth element as the ion seed to enable the drawing on an optional substrate 3 without using any mask, so the process is facilitated and the manufacturing time is shortened.
