The present invention provides a conductive polymer suspension for providing a conductive polymer material having high conductivity and a method for producing the same, and particularly provides a solid electrolytic capacitor having low ESR and a method for producing the same. In an emulsion comprising a dopant of a low molecular organic acid or a salt thereof, obtained by emulsifying a monomer providing a conductive polymer, using a nonionic surfactant, in a water, the monomer is subjected to chemical oxidative polymerization, using an oxidant, to synthesize a conductive polymer. The obtained conductive polymer is purified, and then, the purified conductive polymer and an oxidant are mixed in an aqueous solvent containing a polyacid component to produce a conductive polymer suspension.

In a thin solid electrolytic capacitor including a solid electrolytic capacitor element disposed on a substrate, the solid electrolytic capacitor element has an upper surface largely extending along the substrate as compared with a height dimension thereof from the substrate. A casing portion is at least partly made of a resin and surrounds the solid electrolytic capacitor element jointly with the substrate. The casing portion includes a non-adhesive member that is in contact with an upper surface of the solid electrolytic capacitor element, but is not adhesive to the solid electrolytic capacitor element.

Anodized films are formed at both surfaces of an aluminum base and, at the center portion on each side of the aluminum base, a solid electrolyte layer of a conductive polymer, a graphite layer, and a metal layer are stacked in the order, thereby forming a rectangular cathode portion. An insulator layer is formed at the peripheries of four sides of the cathode portion and, further, an anode lead frame is provided at the peripheries of four sides of the upper insulator layer, thereby forming an anode portion. Openings are formed at four corners of the insulator layer or the anode portion, thereby establishing electrical connection between the cathode portions on both sides of the aluminum base. By setting the ratio of a total region, occupied by the openings, of the cathode portion to 25% or less, the ESL of a capacitor can be suppressed low even when the openings are provided.

A vehicle-mounted antenna system includes a combined antenna apparatus that has a GPS antenna and a short-range wireless communication antenna. The GPS antenna is directional in a vertical direction and the short-range wireless communication antenna is directional in a horizontal direction. The combined antenna apparatus is mounted below an instrument panel of the vehicle by a mounting bracket in such a manner that the short-range wireless communication antenna is directional in the horizontal direction toward an interior of a vehicle. This approach ensures adequate performance of the short-range wireless communication antenna and standardizes a manner in which the short-range wireless communication antenna is mounted to the vehicle.
摘要:
A compensation circuit for protecting a lamp from a large transient current. The compensation circuit may include a saw tooth generator configured to generate a saw tooth signal with an amplitude corresponding to a supply voltage of the lamp. A pulse width modulated signal may be generated by a comparator of the compensation circuit based on the saw tooth signal and a DC signal. The duty cycle of the pulse width modulated signal may be used by a controller to control the duration of time that current flows through the lamp. When the supply voltage of the lamp transitions from a low voltage to a high voltage, the amplitude of the saw tooth signal increases. When the amplitude of the saw tooth signal increases, the duty cycle of the pulse width modulated signal decreases thereby causing the controller to decrease the duration of time that current flows through the lamp.
摘要:
To prevent heat transfer inhibition and an increase in pressure loss due to refrigerating machine oil discharged into a cycle, and to provide a compact and highly efficient refrigerating cycle apparatus using carbon dioxide gas (CO2). In a refrigerating cycle apparatus having at least a compressor, a radiator, a decompressor, a vaporizer and piping for successively connecting them, and provided with a refrigerant circuit in which refrigerant circulates in the compressor, the radiator, the decompressor, the vaporizer and the piping, carbon dioxide gas (CO2) is enclosed as said refrigerant, and the drop in heat transfer rate and the increase in pressure loss in the heat exchanger can be restrained to very low levels by keeping oil enclosing volume in the refrigerant circuit to the quantity of carbon dioxide gas (CO2) enclosed as refrigerant (weight %) to less than 40 weight % and more than 0, resulting in practical elimination of the increase in size and the impact on the drop in efficiency of the heat exchanger.
