Title: Method for succinylating nucleoside
Inventor: ISHIDO RYOJI
IPC: C07H19/167
Filed: 1991-06-20
Abstract: PURPOSE:To efficiently protect amino group in a basic part of a nucleoside with succinyl group by reacting a nucleoside having hydroxyl groups protected with acyl groups with an alkylsuccinyl halide in a basic solvent, and then subjecting the resultant reaction product to cyclizing reaction. CONSTITUTION:A nucleoside such as 2'-deoxyadenosine expressed by formula I is subjected to azeotropic dehydration with pyridine and then dissolved in pyridine. Acetic anhydride is added and reacted therewith at ambient temperature to prepare a nucleoside such as 3',5'-di-O-acetyl-2'-deoxyadenosine expressed by formula II (Ac is acetyl) in which hydroxyl groups are protected with acyl groups. The prepared nucleoside expressed by formula II is used as a raw material compound and dissolved in methylene chloride. An alkylsuccinyl halide (e.g. ethylsuccinyl chloride) is subsequently added in the presence of pyridine to succinylate the amino group in the basic part. A 2N aqueous solution of sodium hydroxide is subsequently added to hydrolyze the resultant compound. Thereby, the objective nucleoside such as N<6>-succinyl-2'-deoxyadenosine expressed by formula III in which the amino group in the basic part is protected is obtained.

Title: Power supply circuit for device
Inventor: KIMOTO SHINJI
IPC: H04N5/00
Filed: 1990-06-07
Abstract: PURPOSE:To prevent malfunction of a main power supply at power restoration by discriminating whether or not the start of supply of an auxiliary power supply from an auxiliary power supply circuit results from the closing of a main power switch and controlling the output of a control circuit only when it results from the closing of the main power switch so as to supply the power from the main power supply circuit. CONSTITUTION:In the case of start of supply of an auxiliary power supply attended with power restoration, the supply of a commercial AC power supply 1 is restarted and a rectified smooth output from a rectifier circuit 4 is supplied to an auxiliary power supply circuit 5, which starts the supply of auxiliary power supply. In this case, since a main power switch 3 is already closed and not brought into the closing operation, both input terminals 10a, 10b of a 1st NAND circuit 10 go to an H level by the supply of auxiliary power and its output goes to an L level. Thus, an output of a 2nd NAND circuit 17 goes to an H level and an output of a 3rd NAND circuit 19 goes to an L level. As a result, an output terminal 6b of a control circuit 6 remains at an L level. Thus, the power from a main power supply circuit 8 is not supplied at restarting.
