IPC: G02F1/133
Filed: 1979-04-16
Abstract: PURPOSE: To apply orientation treatment of good volume productivity and superior moisture resistance, evenness, etc. to transparent electrode substrates by coating the organic titanium compound having hydrolyzable groups on substrate surfaces and heat-treating the same thereby making the film stabler.  
     CONSTITUTION: The solution of isopropyl triisostearoyl titanate, tetraisopropyl titanate, etc. shown by general formula I (R, R' are hydrocarbon groups containing one or more of P, S, N, O, etc.; X is hydrolyzable groups such as alkoxy) or general formula II (R is hydrolyzable groups of C 1W8 ) is coated on a transparent electrode substrate and is heated for about 10 seconds to 60 minutes at room temperature to about 200°C to form film. If necessary, the film is subjected to rubbing. Thence, the liquid crystal display panel is formed by using the substrates having undergone the above-mentioned orientation treatment in accordance with coventional methods. As the nonhydrolyzable groups of organic titanium compounds, the groups having polarity and aromaticity are suited for horizontal orientation treatment and long-chain alkyl groups are suited for vertical orientation treatment.

Title: Manufacture of air electrode
Inventor: KONISHI HAJIME
IPC: H01M4/88
Filed: 1988-02-29
Abstract: PURPOSE:To obtain an electrode having good conductivity by plating nickel on stainless steel wire having a large diameter than a required value, drawing the stainless steel wire to a specified diameter, and forming a net with this nickel-plated stainless steel, then using this net as the core of an air electrode. CONSTITUTION:A stainless steel wire having a larger diameter than a required value for a net is plated with nickel, then drawn to a required wire diameter. A net is formed with the nickel-plated stainless steel wire and used as a core 2 of a catalyst layer against which a porous fluororesin film 3 is pressed. Thereby, a thin nickel layer is uniformly formed on the stainless steel wire. Since the nickel layer is formed prior to making the nickel net, an air electrode which generates no performance defect after cell assembly is obtained at low cost.

CONSTITUTION:The transmission signal supplied through a signal input terminal 10 is transmitted from an LED 13 as an optical signal via a signal modulating circuit 11 and an LED driving circuit 12. The optical signal received from the opposite party side is received by a 1st photodiode 14 and inputted to an addition circuit 21, via a 1st signal detecting circuit 18. Meanwhile the optical signal passed through the gap of a 2nd light shielding plate 17 of the LED 13 is inputted to a 2nd photodiode 15 and then supplied to an addition circuit 21 via a 2nd signal detecting circuit 19 and an attenuator 20. This optical signal eliminates the undesired signal supplies to the photodiode 1.4 from the LED 13. Thus only the optical signal received from the opposite party side is outputted through a signal output terminal 23 via a signal demodulating circuit 22.
