Patent number: 6054678Abstract: A heater/sensor with an electric heating coil has an insulating pipe with a bore therein has nonheating wire threaded therethrough. The nonheating wire is attached to a first end of a heating wire which is wound about the periphery of the insulating pipe. A second end of the heating wire is attached to a second nonheating wire. A first ceramic coating of a binder and a coarse grade alumina is formed on the pipe and wires through a dip process. A second ceramic coating of a binder and a fine alumina coating is formed on the first ceramic coating though a second dip process. The twice coated heater/sensor complex is secured in a soldering iron tip.Type: GrantFiled: March 12, 1998Date of Patent: April 25, 2000Assignee: Hakko CorporationInventor: Mitsuhiko Miyazaki

Patent number: 5837973Abstract: A thermocouple sensor is fitted to an iron tip of an electric soldering iron provided with a temperature controller. The sensor can detect the temperature of the iron tip and supply it to the temperature controller, which then adjusts the temperature to a desired value. The thermocouple sensor is formed of a pair of non-covered sensor wires. A contact point part of the thermocouple sensor is secured to a nose of the iron tip. The wires are laid along the surface of the nose in the rearward direction and introduced into a hollow portion through a lead-in hole opened in the vicinity of the boundary between the nose and a columnar base of the iron tip. Then, the wires are inserted into and through a pair of guide holes, respectively, formed in a cylindrical insulating support of a heater. The distal ends of the wires are coupled to a socket, which is an end portion for receiving a signal representing the detected temperature of the iron tip to supply it to the temperature controller.Type: GrantFiled: July 21, 1995Date of Patent: November 17, 1998Assignee: Japan Bonkote Company LimitedInventor: Toshiharu Tamura
