Title: Preparation of monohydroxyaminoanthraquinone
Inventor: FUJII SHIROU
IPC: C07C225/36
Filed: 1979-11-12
Abstract: PURPOSE: To obtain the titled substance which is a raw material for a dye in high yield stably, by catalytically hydrogenating a mononitroanthraquinone in the presence of a specific reaction medium.  
     CONSTITUTION: A mononitroanthraquinone, e.g. 1-nitroanthraquinone, having no water-soluble group is catalytically hydrogenated in an alcohol with a water content ≤75wt% as a medium in a dispersed state in the presence of a basic substance, e.g. caustic soda, and the reaction is stopped at a time when the hydrogen absorption is 0.8W2.2 times the molar amount of the mononitroanthraquinone. The reaction mixture is then subjected to the solid-liquid separation to give a monohydroxyaminoanthraquinone. The conversion ratio is high in spite of the catalytic hydrogenation, and the by-product formation is slight up to the aminoanthraquinone. The aimed substance is stable for a long time even in the filtrate after the solid- liquid separation.

Title: Current source circuit
Inventor: KANO MASAAKI
IPC: H03F3/45
Filed: 1987-06-11
Abstract: PURPOSE:To easily constitute a high-accuracy constant current source group while making the width of grounding wiring narrower than before and, therefore, reducing chip area by applying a potential lower than the source potential of an N-channel MOS field effect transistor(FET) present in each well. CONSTITUTION:When the source potentials of N-channel transistors(TR) 101-107 for constant current generation need to be raised from the ground zero potential because their grounding wiring is narrow, the potentials of wells are controlled according to the raising quantity to control the threshold values of the respective TRs 101-107 for constant current generation. Consequently, the current quantities of the respective TRs for constant current generation can be adjusted with high accuracy and even if the wiring is narrow, the constant current source group is composed of the TRs for constant current generation having current values nearly proportional to the gate sizes of the TRs.
