  • Patent number: 7066157
    Abstract: A detecting device detects boost condition of each of a plurality of superchargers. The detecting device includes at least two of a pressure ratio detecting unit, which detects the ratio of the pressure downstream each supercharger to the pressure upstream each supercharger; an air flow rate detecting unit, which detects the flow rate of air passing through each supercharger; and a rotational speed detecting unit, which detects the rotational speed of each supercharger. When it is determined that the boost condition of only part of the superchargers is within the surging area, a control unit increases the air flow rate of the supercharger, the boost condition of which is determined to be in the surging area. Therefore, the limitation of the flow rate of air supply is raised.

  • Publication number: 20040211291
    Abstract: There is provided an in-oil atomization method wherein a solder is fused and dispersed in a heated particle dispersion medium, the method being featured in that even if the quantity of the particle dispersion medium to be employed is relatively small, fine solder particles can be effectively obtained. Namely, this invention provides a method of manufacturing fine particles, wherein solder is fused in the heated particle dispersion medium to obtain a molten solder, which is then dispersed by means of an agitator to obtain molten solder particles which are subsequently cooled and solidify, the method being characterized in that the above dispersing step is performed in the presence of a particle coalescence-preventing agent. This invention also provides a fine metal particles-containing substance and a paste solder composition.

  • Patent number: 6790293
    Abstract: There is provided a solder work material for forming solder-coated circuit boards, which is capable of preventing the malfunction of circuit that may be caused to generate by voltage noises that tend to be generated by the volumetrical expansion of the flux residue in a soldered laminated ceramic capacitor, etc. even under the environments where temperatures fluctuate widely (for example, −40° C. to +85° C.), or that may be caused to generate by voltage noises to be generated by the fluctuation of parasitic capacity between circuits which may be caused to generate due to a flux residue. There is also provided a circuit board having a residual film of flux left thereon after the deposition of the solder work material. This solder work material is formed of a solder paste composition or a resin flux-cored solder, both comprising a flux containing, as a resin component, acrylic resin for preventing the generation of voltage noises in electronic devices.

  • Patent number: 6757404
    Abstract: A diaphragm is gained by the co-molded of a dome part, a voice coil junction part, a cone part and a peripheral part through the injection mold of thermoplastic resin. The thickness of the central part of the dome is made great so that the resonance amplitude in this part becomes small. In addition, an annular rib is integrally provided to the voice coil junction part so as to increase the junction strength between the diaphragm and the voice coil bobbin. Thus, the electromagnetic driving force of the voice coil can be effectively transmitted to the diaphragm so that a loud speaker with excellent characteristics can be gained.

  • Patent number: 6680430
    Abstract: A speaker edge is made of a thermosetting composition consisting of a polyurethane prepolymer and an inactivated solid polyamine as a latent hardener. A gas is dispersed in the thermosetting composition, prior to feed into a mold, so that it can foam and solidify to give the speaker edge. In a method of making the speaker edge, the composition will be injected into a female mold segment heated below the critical thermosetting temperature, foaming the composition. Then placed in the female segment is a male segment heated above the critical temperature, causing the ingredients to react with each other to solidify in the mold.
