Publication number: 20240132147Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.Type: ApplicationFiled: October 11, 2023Publication date: April 25, 2024Applicants: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Yuuta KAJISAWA, Yuji FUJITA, Yugo NAGASHIMA, Kazuma HASEGAWA, Takashi KOUDAI, Kaishi MONOBE, Kenichi ABE, Masaharu YAMASHITA, Shintaro TAKAYAMA, Kazuaki IIDA, Yasushi HORA, Yosuke YAMASHITA, Hiroki TOMIZAWA, Nobuyori NAKAJIMA, Hayaki TANABE, Toyohiro HAYASHI, Takeshi IWANA

Publication number: 20130244146Abstract: After performing a pretreatment step of coating an organic solvent mixed with a polymeric organic compound over a substrate having a tungsten film formed on the surface of the substrate, a chemically amplified resist is coated to form a resist pattern. Further, a ratio of a C1s peak intensity to a W4d peak intensity measured by XPS is 0.1 or mote at the surface of the tungsten film after the pretreatment step and before coating the chemically amplified resist.Type: ApplicationFiled: February 4, 2013Publication date: September 19, 2013Applicant: HITACHI, LTD.Inventors: Kazuyuki Kakuta, Toshio Ando, Kenji Hiruma, Toshihiko Onozuka, Kiyomi Katsuyama, Kiyohiko Satoh, Yasushi IIDA
