Abstract: PURPOSE: To obtain a low molecular weight component of a fluoroalkanol useful as a raw material of the sheath material of optical fibers and as a radiation-sensitive resist, economically, with smooth and safe reaction, by introducing tetrafluoroethylene continuously into isopropanol.  
     CONSTITUTION: A fluoroalkanol of formula (n is an integer of ≥1) is prepared by the telomerization reaction of tetrafluoroethylene (TFE) with isopropanol. The continuous introduction of the TFE into the reaction system suppresses the formation of the products of formula wherein n≥3, and gives a telomer mixture composed mainly of the products of formula wherein n<3. The ratio of the partial pressures of TFE to methanol is adjusted between 60/1 and 1/10, and the reaction is carried out under the conditions of the total pressure and reaction temperature designated by the figure ABCDE. The reaction proceeds at a lower pressure, and the pressure resistance of the reactor can be reduced as compared to the one used in the conventional batch process. The rate of reaction can be easily controlled. The average molecular weight of the telomer is adjusted freely and easily to within the range of 170W210.

IPC: H01L29/762
Filed: 1980-08-19
Abstract: PURPOSE:To prevent the lowering of the injection efficiency by sufficiently heightening the transfer conductance of a gate electrode with ease by properly separating an input gate electrode from the surface of a substrate through an Si3N4. CONSTITUTION:As in the past, an n type input diode 21 is formed on a p type Si substrate 20 and an input gate electrode 22 is formed on the surface thereof adjacent to the diode 21. But, the input gate electrode 22 is insulated from the substrate 20 with Si3N4 films 23a and 23b. When a voltage DELTAV (substracting a threshold from a gate voltage) is added to a dielectric constant epsilon and a film thickness theta of Si3N4 with the width Z, length L and carrier mobility mu of the input gate electrode, it gives transfer conductance S=muZ.L<-1>.epsilon.theta<-1>.DELTAV. This can increase the S value by about 1.5 times more than in SiO2 without changing the shape and thickness while improving the injection efficiency of signals. The use of a thermal nitride film provides an extremely favorable characteristics while eliminating complication of the production process.

Abstract: PURPOSE:To prevent malfunction due to noise and supply power stably by controlling so that a low impedance circuit in connection with the primary side winding of a transformer is connected when the chopper on the mating side is turned on. CONSTITUTION:Windings N1, N2 and N4, N5 of transformers T1, T2, giant transistors GTR1, 2, and diodes D3, D4 are connected in series to form two systems of chopper circuits 7, 8. These circuits 7, 8 are driven by turning on and off the transistors Q1, Q2 and ones Q3, Q4 alternately and by differing the phase of a signal V1 180 deg. from the phase of a signal V2, and thereby a current waveform with a high duty ratio is obtained on the output. A low impedance circuit formed by providing windings N7, N8 on the primary side of the transformers T1, T2 is controlled so as to be in connection when the mating circuit 7, 8 to each of them is turned on. Thereby the currents generated by noise from the mating side are consumed with each other and suppressed to ensure that power is supplied stably without risk of malfunction.
