IPC: G03F7/023
Filed: 1985-05-20
Abstract: PURPOSE:To enable mass production of the titled compound by shortening the time necessary for its synthesis, by polycondensing a phenol with an alde hyde or a ketone and esterifying the condensate by continuously adding thereto o-quinonediazidosulfonyl chloride. CONSTITUTION:1pt. by mol of phenol is reacted with 0.7-1.0pt. by mol of aldehyde or ketone at a reaction temperature of -5-120 deg.C for 3-48hr in the presence of an acid catalyst such as hydrochloric acid. After the MW has reached the desired value (e.g., a Mn of 400-7,200 and a Mw of 500-15,000), the polycondensation reaction is stopped by neutralization with an aqueous alkali solution (an acid where an alkali catalyst is used). After the reaction solution from which the formed resin is not isolated is directly concentrated by heating in a vacuum, the undried polycondensate resin together and o- quinonediazidosulfonic chloride are dissolved in a reaction solvent such as dioxane and esterified by heating at 40-50 deg.C with agitation and dropping an alkali such as Na2CO3 to an equivalence point. The precipitated ester produce is filtered and dried to obtain the titled compound in yield >=90%.

IPC: H04B10/50
Filed: 1981-07-15
Abstract: PURPOSE:To obtain a high-speed pulse driving current with a simple circuit constitution, by constituting the device of an emitter coupled transistor (TR) logical circuit which converts a non-return-to-zero signal into a return-to-zero signal and a clock applying means. CONSTITUTION:Transistor TRs 210 and 211 and a resistance 213 constitute a CML (current mode logical circuit). An NRT (non-return-to-zero) signal is supplied to an input terminal (a'), its inverted signal is supplied to an input terminal (a), and a clock signal is supplied to an input terminal (b) to obtain an RZ (return-to-zero) signal at the collector of the TR211, with which a laser diode LD201 is pulse-driven. The DC bias current of the LD201 is supplied to a terminal (c). The collector current of the TR211 flows only when the potential at a terminal (f) rises above that at the terminal (a'), so this circuit converts the NRZ signal into the RZ signal. Further, the load impedance of the collector of a TR212 is low, so the TR212 operates at a high speed. Therefore, a high-speed LD driving current pulse is obtained.
