Patents by Inventor Kayoko Yoshimura

Kayoko Yoshimura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8569657
    Abstract: A soldering iron (and a desoldering iron) with a replaceable tip, which is releasably securable on the forward heat-conducting end of a soldering (or desoldering) iron heat assembly. The tip has a heat conducting core in a tip cap. Methods of manufacturing and using the tip are also disclosed. A method of manufacturing a replaceable soldering or desoldering iron tip can comprise preparing a cap having a base opening and at least substantially filling the cap through the base opening with a heat conducting material so that a tip core is formed in the cap, the tip core having a core face at the base opening.
    Type: Grant

  • Patent number: 8237091
    Abstract: A soldering iron (and a desoldering iron) with a replaceable tip, which is releasably securable on the forward heat-conducting end of a soldering (or desoldering) iron heat assembly. The tip has a tapered heat conducting core in a tip cap. The face of the core can have a depression for mating engagement with a protrusion of the heat-conducting end. Also, the face can lie in the rear plane of the tip cap. An assembly which allows for the easy removal and application of a replacement tip can include a sleeve with tightening bolt, a coil spring sleeve, or a slotted compressible sleeve. The tip can thus be replaced after it has worn out, and the heat assembly unit need not be replaced until it has burnt out. Methods of manufacturing and using the tip are also disclosed.

  • Publication number: 20060081680
    Abstract: A desoldering wick having an inner metal coating such as a 0.1 ?m to 12 ?m layer of tin or tin-alloy and an outer noble metal coating such as a 0.5 nm to 10 ?m layer of gold, silver, platinum, palladium, or rhodium for the removal of lead-free solder; a method of manufacturing the desoldering wick; and methods of using the wick.
