Abstract: An electric machine system includes an electric machine, an electric power converter, and a control unit. The electric machine includes a stator that includes coils, and a rotator that includes a magnet and is rotatable with respect to the stator. The electric power converter inputs electric power with respect to the coils of the electric machine. The control unit controls the electric power converter. The control unit includes an output unit and a correction unit. The output unit outputs a control signal for operating the electric power converter to the electric power converter. The correction unit corrects a phase of the control signal that determines input timing of the electric power with respect to the coils of the electric machine. The correction unit corrects the phase so that the magnitude of the electric power approaches an extreme value.

Abstract: A dental adhesive curable composition containing a polymerizable monomer including a polymerizable monomer represented by formula (1?) and defined amounts of an acidic group-containing polymerizable monomer, a polymerization initiator containing a peroxide and a photopolymerization initiator, and a reductant containing a sulfinic acid compound and/or a salt thereof, and a filler: wherein the R groups, n and m are defined. A dental adhesive curable kit and a mobile tooth fixing material are also provided.

Abstract: An immunosuppressive agent which has low toxicity and which exhibits excellent effectiveness even if it is orally administered is presented. The immunosuppressive agent of the present invention is characterized in that it contains .delta.-opioid antagonist having high selectivity to .delta.-opioid receptor. The present invention also provides a process of producing a naltrindole derivative characterized by reacting naltrexone or a salt thereof with a phenylhydrazine derivative in a solvent in the presence of methanesulfonic acid.

Abstract: This invention concerns a process for producing phenolic substances with beneficial biological activities in a high yield, which comprises: subjecting a glycose of which an OH group at the 1 position is substituted for a halogen atom and of which other groups are substituted for acyl groups, and a phenol of which at least one of the ortho-positions in regard to phenolic OH groups is substituted to reaction with an alkali metal hydride in dimethylsulfoxide or dimethylformamide in the presence of or non-presence of a quat-ammonium salt and then hydrolyzing said acyl groups with an alkaline substance.
