Title: Dimming control circuit for discharge lamp
Inventor: IDE KATSUYUKI
IPC: H05B41/392
Filed: 1989-04-28
Abstract: PURPOSE:To reduce power consumption, simplify the circuit, and suppress the costs by forming each control switch circuit from specific switches, No.1 and No.2. CONSTITUTION:A control switch circuit is composed of No. 1 switch Q7, which is connected in series to a discharge lamp LP as the load, and No.2 switch Q4 connected in parallel with the same. A pulse width control signal is used first for control of the No.2 switch Q4, and No.1 switch Q7 operates in compliance with the motion of the No.2 switch Q4. That is, transistor Q4 is turned on when the pulse width control signal impressed between terminals T2 and T3 is at 'H' level, while transistor Q7 is turned off to cause extinction of the discharge lamp LP. Thereby wasteful shortcircuiting current when the discharge lamp LP is extinguished can be shut off to contribute to reduction of power consumption, and also the circuit configuration be simplified to lead to cost-down.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain an N-formylamine which is a precursor of an amine useful as an intermediate for medicines and agrochemcials in high yield. SOLUTION: This f-ormylamine is represented by the formula: R<1> R<2> CH NH CHO (R<1> is an alkyl, an aralkyl; R<2> is an aryl, an aralkyl) and is typically N-formyl-1-phenylethylamine. The objective formylamine is prepared by dripping a combination of an ketone of the formula: R<1> R<2> C=0 (for example acetophenone) and formic acid to formamide and/or ammonium formate. The formic acid used in the reaction preferably contains ammonium formate formed by allowing formic acid to absorb the ammonia generated from the reaction system. The reaction is carried out at 155-175 deg.C for about 0.5-10 hours and the reaction mixture is preferably aged by stirring the reaction mixture for about 1-10 hours after completion of the dripping.
