Filed: 1989-05-02
Abstract: PURPOSE:To obtain an image of high quality which has no flicker and uniform accuracy by forming by-pass capacity between an auxiliary capacity electrode and a counter electrode, providing a resistance element between an auxiliary capacity electrode group and a counter electrode group, and applying a voltage which changes in polarity to the auxiliary capacity electrode group. CONSTITUTION:The by-pass capacity 31 is formed between the auxiliary capacity electrode 35 and counter electrode 17 so as to eliminate waveform distortion which is generated by the resistance component of the counter electrode of a rectangular picture element. Then a signal voltage is applied to the series connection body of the by-pass capacity 31 and the liquid crystal capacity of the picture element part through the auxiliary capacity electrode 35. The auxiliary capacity electrode 35 can easily be formed having a smaller resistance value than the transparent counter electrode 17, so a rectangular wave having no distortion can be transmitted to the counter electrode of the rectangular picture element part. Consequently, the counter electrode never decreases in resistance and the counter electrode of the picture element part can be driven; and the manufacture cost of the transparent electrode is reduced and the image of high quality with a uniform display can be obtained.

Title: Optical switch element
Inventor: NODA SUSUMU
IPC: H01S3/10
Filed: 1988-05-09
Abstract: PURPOSE:To turn on and off an optical switch with external light by providing absorption media which have different light absorption characteristics to the intensity of input light in a resonator. CONSTITUTION:A gain medium 3 is given a gain by the excitation of a current or light and light emitted by the gain medium 3 travels reciprocally in the resonator composed of reflecting mirrors 1 and 2. At this time, the intensity of the light emitted by the medium 3 is <=Ith1 and the light is absorbed much by a 1st absorptive medium 4 and does not cause laser oscillation. Then when external light A having such light intensity I that Ith1<I<Ith2 is incident on the 1st absorptive medium 4, the absorption loss in the resonator becomes small and the laser oscillation is caused to turn on the switch. When the excitation intensity of the medium 3 is so adjusted that when the laser oscillation is caused, the oscillation intensity is between Ith1 and Ith2, the switch is held on continuously even after the external input light A is creased. Further, when such external input light B that I>Ith2 is made incident on a 2nd absorptive medium 5, its absorption increases, so the loss in the resonator increases and the laser oscillation is stopped, so that the switch is turned off.

CONSTITUTION:An Al layer 2 is formed on the surface or a substrate 1, then a porous layer 3 is formed by anodizing the Al layer 2. Then, a layer 5 coated with powder of a precursor of a superconductor or a superconductor is formed on the porous layer 3, and the coated layer 5 is sintered by heat-treating the substrate 1 thereafter to form thus a superconductor layer 6. In this case, such substrate obtd. by heating a substrate 1 having the porous layer 3 formed thereon at >=1100 deg.C in O2 atmosphere transforming thus the Al layer 2 to a thermally stable alpha-alumina layer, is preferred for the prepn. of the superconductor. A superconductor having a larger film thickness and superior superconducting characteristics is obtd. by filling an oxidizing agent 7 into pores 4 of the porous layer 3 prior to the formation of the coated layer 5, then executing the formation and the heat-treatment of the coated layer in the above described process.

In a data communication system like this, when the node receives packets of ack- busy- X, ack- busy- A and ack- busy- B at the time of OSR 0 state, the system recognizes that a node of a received party is in a busy state. In this case, the necessity of retry occurs and the node transits to OSR 1 state. Then, at the time of the OSR 1 state, a minimum retry cycle is set.
