Title: Production of 4-vinylbiphenyls
Inventor: SHIRAKI YASUSHI
IPC: C07C15/50
Filed: 1990-11-30
Abstract: PURPOSE:To obtain the title substance by subjecting a 4-ethylbiphenyl--containing mixture to dehydrogenating reaction while introducing steam to the mixture, adding a good solvent for the objective substance to the prepared reaction mixture, quenching and then concentrating. CONSTITUTION:A 4-ethylbiphenyl-containing hydrocarbon mixture is subjected to dehydrogenating reaction in the presence of an iron-based dehydrating catalyst at 580-640 deg.C while introducing 5-15 times as much steam as the mixture by weight. A good solvent (e.g. benzene or toluene) for the objective substance is added to the prepared reaction mixture, which is then quenched and concentrated. The concentrated solution is incorporated with 7-15 times volume of a lower alcohol (e.g. methanol) having 95% purity as the solution and the title substance is separated and purified by crystallization. The high-purity objective substance can be obtained by such simple reactional operation and separating and purifying operations. Especially, since long-term continuous operation of dehydrogenating reaction is possible, this process 15 advantageous as a large scale production method.

Abstract: PURPOSE:To obtain an S-FET which has a higher switching speed by a method wherein doping quantity of impurities is controlled and a gate voltage region to which a surface diffusion has no or very little contribution is produced and the S-FET is operated in the region. CONSTITUTION:When an Nb-Si-Nb system S-FET is composed, Schottky barriers are formed in both the surfaces between a source 1 and a semiconductor layer 5 and between a drain 6 and the superconductor layer 5 by the difference in work functions. In order to reduce the thicknesses of the Schottky barriers, high impurity concentration doped layers 2 are provided in the semiconductor layer near the surfaces. If the whole semiconductor layer 5 is doped with impurities whose type is different from the type of carriers, the gate voltage dependency of the mobility of the carriers is varied in accordance with the doping quantity of the impurities. Therefore, as the impurity concentration necessary for having a peak gate voltage 1V is valued at approximately 1X10<+11>cm<-2>, by selecting this value, an S-FET which facilitates a higher switching speed than a conventional constitution with the gate voltage not higher than 1V can be obtained.

IPC: G06F17/28
Filed: 1989-12-20
Abstract: PURPOSE:To enable anyone to accurately input necessary words by inhibiting the input of information read before the presence of a blank into an information processing means if a prescribed blank is included in the read information. CONSTITUTION:When a prescribed blank is included in the information read by a reading means 2, the input preventing means 11 and 18 prevent the information read before the presence of the blank from being inputted to an information processing means 12 via a character recognizing means 8. Therefore, for instance, when it is impossible to satisfactorily set the means 2 in a space between words since the space is small, the middle of a word preceding the word to be inputted is read so that only the necessary words can be easily and accurately inputted. Thus anyone can input accurately the necessary words regardless of the size of the means 2 and the space size. Then the information is effectively processed.
