Patent JP-H03273704-A (JP)
Title: Amplifier
Inventor: NAKAMURA ICHIRO
IPC: H03F3/50
Filed: 1990-03-22
Abstract: PURPOSE:To simplify the circuit constitution and to improve the stability for an amplifier by connecting a current source to the forward and opposite phase outputs via one resistances together with the differential input of a DC amplifier connected to the junction between the resistance and the current source and the output of a DC amplifier connected to a control terminal of the current source respectively. CONSTITUTION:The signal inputted to an input terminal 2 of a DC amplifier 1 is amplified by the amplifier 1. Then the forward phase signal is outputted to an output terminal 14 via a low impedance converter 5 and a resistance 7. Meanwhile the opposite phase signal is outputted to an output terminal 13 via a low impedance converter 6 and a resistance 8 respectively. Then a DC amplifier 12 connected to both terminals 13 and 14 as well as to a control terminal 11 of a current source 10 functions to reduce the current of the source 10 against the rise of the voltage level of the terminal 14 and then functions to increase the current of the source 10 against the fall of the voltage level of the terminal 14 respectively. That is, the same offset voltage level is secured between both terminals 13 and 14. In such a way, the input offset voltage is compensated in the output part of an amplifier. Hence the highly stable working is secured in a simple constitution.

Abstract: PROBLEM TO BE SOLVED: To enhance antimicrobial activities of an antibiotic substance against methicillin-resistant Staphylococcus aureus (MRSA) by adding tea catechins and/or theaflavins to the antibiotic substance. SOLUTION: Tea catechins containing epigallocatechin gallate as a principal ingredient and/or theaflavins containing theaflavin digallate as a principal ingredient are added to an antibiotic substance such as a β-lactam-based or an aminoglycoside-based antibiotic substance (e.g. oxacillin or methicillin) without manifesting antimicrobial and germicidal actions on MRSA alone. The antibiotic substance is used in an amount of 2-35μg/ml and the tea catechins are used in an amount of 5-120μg/ml. The theaflavins are used in an amount of 5-100μg/ml. The antimicrobial actions of the respective antibiotic substances manifested in the presence of 100μg/ml tea catechins are 5μg/ml oxacillin, 12.5μg/ml methicillin, 32μg/ml aminobenzylpenicilin, 2.5μg/ml tetracycline and 12.5μg/ml chloramphenicol.  The blending amounts of the tea catechins and theaflavins are preferably suitably determined by using the above data as a measure.

Title: Power unit, discharge lamp lighting device, and lighting system
Inventor: OSAKI HAJIME
IPC: H02M7/48
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent damage to switching elements by preventing high-frequency voltages output from the switching elements from entering an advanced mode even when a lamp turned on burns out. SOLUTION: A comparator 6 compares the applied voltage of a discharge lamp 4 with a reference voltage Vref2 to detect the preheating and ON times of the discharge lamp 4. During the preheating time, a transistor Tr3 is turned off and the minimum value of the oscillating frequency of a voltage-to-frequency converting circuit is made slightly higher than the resonance point of an output circuit involving the discharge lamp 4 during the preheating time; during the ON time, the transistor Tr3 is turned on, and the minimum value of the oscillating frequency is set to be slightly higher than the resonance point of the output circuit involving the discharge lamp 4 during the ON time.  Thus even if the discharge lamp 4 burns out and enters the preheating mode, the oscillating frequency of the voltage-to-frequency converting circuit 5 is set at least to the minimum value during the preheating time to prevent high-frequency voltages output from transistors Tr1, Tr2 from entering the advanced modeso as to make it possible to prevent damage to the transistors.
