摘要： PROBLEM TO BE SOLVED: To reduce output ripple voltage and output ripple noise through a relatively simple circuit. SOLUTION: The choke input-type smoothing circuit of a single forward converter is formed by parallel-connecting a plurality of smoothing capacitors subsequent to an input choke coil. An inductance L1 is connected between an input-side capacitor C1 and an output-side capacitor C2 parallel-connected subsequently to the input choke coil L2 to form a n-type filter circuit 3. A small inductance that sets the current ratio (ir2/ir1) of the ripple current of the output-side capacitor C2 to the ripple current of the input-side capacitor C1 to a value within a range less than 1 and not less than a fraction is used for the inductance L1 of the n-type filter circuit 3.

摘要： PROBLEM TO BE SOLVED: To obtain a gas sensor which can stably and correctly detect a volatile organic substance with a high detect sensitivity by adding or holding a manganese oxide to a tin oxide of a gas-sensing body in a gas sensor with the gas- sensing body essentially consisting of tin oxide. SOLUTION: Surface electrodes 12 and 13 baked with a platinum paste printed are formed on a surface of an insulating substrate 10 formed of ceramics such as alumina or the like. A gas-sensing body 16 with a manganese oxide added to a tin oxide semiconductor is printed and baked between the electrodes 12 and 14. The gas-sensing body 16 is obtained by mixing 0.5-20 wt.% of manganese oxide with a tin oxide powder, adding a vehicle essentially consisting of, e.g. ethyl cellulose to the powder thereby obtaining a paste, and printing and baking the paste on electrodes of the alumina substrate. A platinum heater 18 is formed on a rear face of the substrate 10. Platinum lead wires 24 and 26 are connected to both ends of the heater 18, and platinum lead wires 20 and 22 are connected to the surface electrodes 12 and 14 respectively.

摘要： PROBLEM TO BE SOLVED: To reduce the loss in the commutation section by inputting a pulse signal of specific frequency from a pulse input circuit to a switch element and driving switch element to commutate or switch the input pulse signal through a drive circuit. SOLUTION: On the primary of a single forward converter which can be regarded as a pulse input circuit 100, an input DC power supply 1 and a main switch element 2 are connected with the primary winding 3a of a transformer 3 so that an in-phase pulse signal is induced in the secondary winding 3b of the transformer 3. The secondary winding 3b of the transformer 3 is followed by a synchronous commutation circuit 102A for rectification which is followed by a synchronous commutation circuit 102B for commutation and a pulse signal from the secondary winding 3b of the transformer 3 is commutation commutated or switched. This circuitry can enhance conversion efficiency of the commutation circuits 102A, 102B.

摘要： PROBLEM TO BE SOLVED: To reduce a rush current, while power loss increase caused by the decline in an input voltage is prevented. SOLUTION: A power thermistor 7 which suppresses a rush current applied to a smoothing capacitor 8, when a power supply is closed is connected in series between an output rectifying device 6 and the smoothing capacitor 8 of a step-up chopper circuit 100. Since the output voltage of the step-up chopper circuit 100 is controlled to be constant, it power is constant, the average value of an output current is controlled to be constant regardless of the input voltage, and the loss of the power thermistor 7 will not increase when the input voltage is low. Furthermore, by reducing the loss of the power thermistor 7, a power thermistor 7 with a larger resistance can be employed.
