Patent number: 11772186Abstract: A novel spot welding method for steel sheets and an aluminum alloy sheet, includes stacked sheet materials from a pair of opposing electrodes to join the sheet materials by resistance heating. The pair of opposing electrodes are in pressure contact with both outer surfaces of the sheet sets. The sheet sets include at least a first and second steel sheet, and an aluminum alloy sheet stacked in this order. A first energization step forms a molten pool between facing surfaces of the first and second steel sheets without melting the aluminum alloy sheet. A second energization step causes a melting reaction between facing surfaces of the second steel sheet and the aluminum alloy sheet. The first and second steel sheets are joined via a first nugget. The second steel sheet and the aluminum alloy sheet are joined via a second nugget including an intermetallic compound generated by the melting reaction.Type: GrantFiled: July 12, 2021Date of Patent: October 3, 2023Assignees: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideaki Matsuoka, Takashi Asada, Tatsuyuki Amago, Kyosuke Izuno, Koki Nakada, Tomohiko Sekiguchi, Shuhei Ogura

Patent number: 11289081Abstract: In a refrigerator, when a door switch detects opening of a door of the refrigerator, a voice recognition control unit determines whether voice data acquired by a voice acquisition unit satisfies a predetermined voice recognition start condition. In a case where the voice recognition start condition is satisfied, the recognition control unit controls the voice recognition unit to perform voice recognition. However, in a case where the voice recognition start condition is not satisfied, the recognition control unit controls the voice recognition unit not to perform voice recognition.Type: GrantFiled: October 30, 2019Date of Patent: March 29, 2022Assignee: SHARP KABUSHIKI KAISHAInventors: Takashi Asada, Seishiro Otoge, Kinya Yamade

Patent number: 11247293Abstract: A highly corrosion-resistant spot weldment can be produced at low cost without occurrence of prominent protrusions and the like on the surface. The spot weldment is joined by a nugget formed inside stacked sheet materials through bringing a pair of electrodes arranged opposite to each other into pressure contact with the stacked sheet materials from outside and energizing the stacked sheet materials from the electrodes. The nugget has a diameter that is ?4?t (t: thickness of sheet material) and a flattening level of 3.5 to 8, which is a ratio of diameter to thickness. Both outer surface parts of the sheet materials are free from protrusions formed due to bulging of molten metal. Even when the electrodes are made of a copper alloy, the increased amount of Cu in the outer surface parts is 0.2 mass % or less with respect to the component composition before spot welding.Type: GrantFiled: September 19, 2019Date of Patent: February 15, 2022Assignees: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideaki Matsuoka, Tatsuyuki Amago, Takashi Asada, Toru Hioki, Manabu Ooga, Shuhei Ogura
