Title: Method for disproportionating methylnaphthalene
Inventor: MAKI TAKAO
IPC: C07C15/24
Filed: 1983-10-25
Abstract: PURPOSE:To obtain advantageously a dimethylnaphthalene (a raw material for polyester films, etc.) and naphthalene (a reagent for organic synthesis), by disproportionating a methylnaphthalene in the presence of a zeolite having an inlets of main pores consisting of oxygen 10-membered rings as a catalyst. CONSTITUTION:A methylnaphthalene is brought into contact with a zeolite having inlets of main pores consisting of oxygen 10-membered rings, e.g. ZSM-5, 8, or 11, etc. preferably at 350-550 deg.C under ordinary pressure -20 atm pressure to give a dimethylnaphthalene, preferably 2,4-dimethylnaphthalene and naphthalene useful as a raw material for films or fibers. Products other than the above- mentioned compounds are mostly methylnaphthalene isomers, which can be recirculated as a raw material for use. Thus, this method has very high effectiveness, and the regeneration frequency is low due to the little deposition of carbon on the catalyst. The method is therefore very advantageous from the economic standpoint.

Title: Manufacture of field effect transistor
Inventor: HIROSE TAKASHI
IPC: H01L29/812
Filed: 1985-09-10
Abstract: PURPOSE:To realize high (gm) and improve high speed performance of an MESFET by a method wherein a source and a drain of the MESFET are formed on a GaAs semi-insulating substrate as epitaxial layers with an active layer in between. CONSTITUTION:As source and drain layers 28 of a GaAsFET are formed by epitaxial growth, heat treatment for activation of the source and drain layers 28 is not necessary and hence variation of the distribution, caused by thermal diffusion, of impurity ions which compose carriers is not created. Moreover, as the source and drain layers 28 are formed on an active layer 22 and do not touch a GaAs semi-insulating substrate directly, leakage current flowing from the low resistance source and drain layers 28 to the semi-insulating substrate 21 can be reduced and short-channel effect can be suppressed. With this constitution, high (gm) and significant improvement of high frequency characteristics can be realized.
