Abstract: 본 발명은 전원장치에 있어서 부하변화량에 따른 출력전압의 오차를 검출하기 위한 출력전압의 오차검출회로 및 방법에 관한 것이다. 이를 위하여 인가되는 전원전압에 대하여 적어도 하나 이상의 DC 전압을 출력하고, 전원장치의 출력전압을 조절하기 위하여 부하의 변동에 의해 발생되는 상기 적어도 하나 이상의 DC 전압의 변화량을 피드백하기 위한 피드백수단을 구비한 전원장치의 출력전압의 오차검출회로에 있어서, 상기 하나의 DC 전압에 있어서 상기 부하의 변동에 따른 AC 레벨의 변화량을 검출하기 위한 AC 레벨 변화량 검출수단과, 상기 적어도 하나 이상의 DC 전압에 있어서 상기 부하의 변동에 따른 DC레벨의  변화량 검출하기 위한 DC 레벨 변화량 검출수단과, 상기 AC 레벨 변화량 검출수단에서 출력된 AC 레벨 변화량과 상기 DC 레벨 변화량 검출수단에서 출력된 적어도 하나 이상의 DC 레벨 변화량을 소정의 기준레벨과 비교하여 상기 피드백수단으로 인가하기 위한 비교수단으로 구성된다. 따라서 부하에 변동에 상관없이 복수의 출력전압을 일정하게 유지시키는 이점이 있다.

Abstract: A novel microbiological process for the preparation of hydroxylated heterocyclic carboxylic acids of the formula <IMAGE> starts from the corresponding heterocyclic carboxylic acid. This process is carried out in such a way that a) aerobic biomass which utilises nicotinic acid is cultivated in a molar ratio of nicotinic acid to mineral acid of 1 to 8, this ratio being ensured throughout the culture period, and then b) the hydroxylation of the corresponding heterocyclic carboxylic acid of the general formula. <IMAGE> in which R1 and X have the said meaning, is carried out with this biomass. Under these conditions it is possible in the culture period to accumulate microorganisms of the species Pseudomonas acidovorans DSM 7205, of the species Pseudomonas acidovorans DSM 7203, of the species Alcaligenes faecalis DSM 7204 and microorganisms with the identifier DSM 7202.

Abstract: The device can classifies a completion-type code and a combination-type code on hardware. It is composed of: (i) a Hangul recognizer(10) which gets a input code and MSB examines them and, if the code is Hangul, generates a Hangul Enable signal(HE); (ii) a font ROM address generator(20) which examines MSB of the second byte of the input code when the Hangul Enable signal(HE) is "1", generates a completion-type address if the MSB is "1" and generates a combination-type address if the MSB is "0"; (iii) a font ROM Enable signal generator(30) which generates a ROM controlling signal(CTL) according to the MSB of the second byte of the code when the Hangul Enable signal(HE) is "1".

Abstract: The method comprises the steps of forming a metal pattern of a cathode ray tube on a metal plate; forming a clip to enable a cathode ray tube pin to be inserted into the metal pattern; making a one-body with the metal pattern by forming a discharging hall in a radial direction on the top of the metal plate, and by exposing a metal part in the rear of the clip to outside; forming a discharging cap by cutting the exposed metal unit through the discharging hall of the main body; putting a cover on the top of the main body; and curving a connection terminal of the metal pattern by separating the main body from the metal plate.
