  • Patent number: 11945051
    Abstract: A heater-sensor complex 10 includes a heating wire 12, a lead wire 14 which is made from the same metal of the heating wire 12 and connected to the proximal end of the heating wire 12, the lead wire 14 having a bigger diameter than the heating wire 12, a non-heating wire 16 constituted by a different metal from the metal constituting the heating wire 12, and a sensor head 18 constituted by a metal different from the metal constituting the heating wire 12 or the metal constituting the non-heating wire 16. The sensor head 18 have a lower thermal conductivity than the non-heating wire. To the sensor head 18, the distal end of the heating wire 12 and the distal end of the non-heating wire is connected. The heating wire 12 and the non-heating wire 16 electrically conducts at least through the sensor head 18.

  • Publication number: 20230405700
    Abstract: A control device includes an acquisition portion which acquires a detection value of a temperature detected by a detecting member, a specifying portion which specifies a temperature change trend of a solder processing portion based on history information of a detection value acquired by the acquisition portion, a setting portion which sets a number of heat pulse to be applied to a heating portion by correcting a reference value using a correction value, a control portion which controls the application of the heat pulses to the heating portion based on a setting result of the number of heat pulse by the setting portion, a storage portion which stores the history information. The setting portion sets the correction value using correction information which is different according to whether the temperature change trend is a temperature rising trend or a temperature declining trend.

  • Patent number: 10406619
    Abstract: A heater cartridge comprises a heater contained within a distal section of housing pipe near a working portion, such as soldering iron tip or a blade for stripping wire. The wall thickness of the housing pipe is generally thin to limit heat transfer to a proximal section of the housing pipe near where a user's hand would be normally located. The wall thickness is thinner in a region near the heater as compared to a region expected to have a high bending moment.
