Patent number: 8969751Abstract: A method of detecting dust includes: a first step of monitoring a resistance value welding and determining if a variation amount of the resistance value per unit time is equal to or more than a first threshold; a second step of monitoring the resistance value after the first step and determining if a variation amount of this resistance value per unit time is equal to or less than a second threshold; a third step of determining if a difference value between a resistance value for calculating the variation amount equal to or more than the first threshold and a resistance value for calculating the variation amount determined equal to or less than the second threshold is equal to or more than a third threshold; and a fourth step of determining that dust is generated when the difference value is equal to or more than the third threshold.Type: GrantFiled: September 30, 2009Date of Patent: March 3, 2015Assignee: Honda Motor Co., Ltd.Inventors: Masamitsu Numano, Junya Tanabe, Tetsuro Hayashi

Patent number: 8450634Abstract: A resistance welding apparatus is provided with: a pair of electrode chips; a power supply device for supplying the electrode chips a welding current; and a spattering detecting device that detects a spattering. The power supply device supplies to the electrode chips a preset welding current until the spattering is detected. The power supply device supplies a current on which an additional current is added to the preset welding current, after the spattering is detected, until a preset energizing time expires.Type: GrantFiled: September 23, 2008Date of Patent: May 28, 2013Assignee: Honda Motor Co., Ltd.Inventors: Masamitsu Numano, Yuya Ishikawa

Patent number: 7596861Abstract: A vehicular body panel or component part having a reinforcing backing plate reconciled or joined to a part of a blank material at a position wherein a bending formation is implemented. The backing plate has one or more apertures formed in at least one lateral row at a location equivalent to the position of the bending formation. When forming the blank material and the backing plate concurrently by a bending operation, the backing plate becomes intimately associated with the blank sheet to avoid the backing plate from locally separating from the blank material and from forming a gap relative thereto, with a resultant improved product quality.Type: GrantFiled: February 10, 2006Date of Patent: October 6, 2009Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Teruo Kamada, Noriaki Iwanami, Masamitsu Numano, Takashi Tsuchiya

Publication number: 20070023158Abstract: Electrodes are embedded respectively in a first die and a second die. A metal workpiece is placed in a cavity defined between the first die and the second die which mate with each other. Then, a molten metal is poured through a passage into the cavity. The molten metal is solidified into a casting, forming a contact region of the metal workpiece and the casting. Thereafter, an electric current is supplied from a power supply between the electrodes across the contact region. The supplied electric current breaks an oxide film that is present on the surface of the metal workpiece, and joins the metal workpiece and the casting in the contact region.Type: ApplicationFiled: July 31, 2006Publication date: February 1, 2007Inventors: Toshihiro Murakawa, Jun Kitagawa, Akira Goto, Masamitsu Numano
