  • Patent number: 6350406
    Abstract: A method of manufacturing a sintered anode unit for a solid electrolytic capacitor is provided. According to this method, a press-molded or compacted pellet of a valve-action metal powder is sintered at a predetermined high temperature and in a predetermined primary vacuum. The pellet is naturally cooled in this primary vacuum, and is cooled by force cooling in an inert gas atmosphere. Thereafter, the sintered pellet is subjected to a repeated cycle processing of vacuum, atmospheric leakage, and vacuum in a gradual-oxidizing chamber. The atmospheric leakage level is increased step by step to set the vacuum level in the gradual-oxidizing chamber to the atmospheric pressure. Then, the sintered pellet having the restricted content of oxygen is taken out from the gradual-oxidizing chamber into the atmosphere.

  • Patent number: 6294826
    Abstract: A molded elecronic component such as a solid electrolyte capacitor comprising a capacitor element including a cathode layer, an anode lead, a pre-plated anode lead terminal connected to the anode lead, a pre-plated cathode lead terminal connected to the cathode layer, and an insulating member which encapsulates the capacitor element and leaves a portion of the anode and cathode lead terminals exposed. The encapsulated portions of the pre-plated anode and cathode lead terminals have a plating layer formed thereon containing organic substances in an amount of 0.03 wt. % or less. Also disclosed is a process for manufacturing the solid electrolyte capacitor.

  • Patent number: 4832086
    Abstract: In construction of an insertion controller for a fluid jet loom in which a driver circuit controls the sequence of weft insertion following a regular sequential weft insertion pattern given by an automatic weft selector, a free selective weft selection by a manual weft selector is introduced for free and easy adjustment of weft insertion with provisional reservation of the regular sequential weft selection pattern.

  • Patent number: 4393903
    Abstract: On a electrode pair type weft feeler unit for a fluid-jet loom, electric connection between electrodes due to electric discharge to be caused by use of high electric voltage is assimilated to electric connection caused by direct contact of a normally inserted weft with the electrodes in order to enable reliable detection of weft insertion even when a high twist yarn is used for the weft.
