Patent number: 11920936Abstract: A vehicle controller determines whether the position of a detected travel lane relative to an edge of a road being traveled by a vehicle may differ from an actual position; estimates a first required time for an action, which is required before the vehicle reaches a predetermined location, for the case that the position of the detected lane relative to the edge of the road is correct; estimates a second required time for the action for the case that the position of the detected lane differs from the actual position by a predetermined number of lanes; and sets start timing of the action, based on the second required time, so that the action will finish before the vehicle reaches the predetermined location, when the position of the detected lane may differ from the actual position and the second required time is longer than the first required time.Type: GrantFiled: March 28, 2022Date of Patent: March 5, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takahiro Seta, Ryuta Hashimoto, Kota Harada, Soichi Yoshino

Patent number: 6432612Abstract: An ultraviolet-curable type photo solder resist ink comprises the following components (A) to (E). That is. the component (A) is an ultraviolet-curable resin having at least two ethylenically unsaturated groups and a carboxyl group per one molecule thereof. The component (B) is an epoxy compound having at least two epoxy groups per one molecule thereof. The component (C) is at least one selected from a compound having at least one carboxyl group and a polycarboxylic acid anhydride. The component (D) is a photopolymerization initiator. The component (E) is a diluent. This photo solder resist ink shows a good developing property even when a developer having a pH value of about 10 is used, and is excellent in a storage stability of resist, electrical corrosion resistance, electric performance, chemical resistance, plating resistance, heat resistance to solder, adhesion, and pencil hardness.Type: GrantFiled: February 23, 1999Date of Patent: August 13, 2002Assignee: Goo Chemical Co., Ltd.Inventors: Nobuhito Hamada, Koichi Yoshioka, Soichi Hashimoto

Patent number: 6136506Abstract: An ultraviolet-curable and alkali-developing type photo solder resist ink comprises an epoxy resin obtained by extending chains of an epoxy compound by an isocyanate compound having at least two isocyanate groups per one molecule of the isocyanate compound, an ultraviolet-curable resin having carboxyl group and an ethylenically unsaturated group having a photopolymerization capability, a photopolymerization initiator, and a diluent. The resist ink shows a wide precuring acceptable width for providing an extended shelf life, a good tacky-dry property after a precuring step, excellent light-sensitivity at an exposing step, superior resolution, and improved removability of a film of the resist ink by an alkaline solution at a developing step. In addition, a solder resist obtained by a post-baking step of the resist ink film provides excellent resistances to molten solder and gold plating.Type: GrantFiled: June 22, 1998Date of Patent: October 24, 2000Assignee: GOO Chemical Co., Ltd.Inventors: Soichi Hashimoto, Koichi Yoshioka, Masahiro Mizushima, Toshikazu Oda

Patent number: 5821031Abstract: Disclosed herein is a photosensitive solder resist ink capable of development with a dilute alkaline solution. It has a wide pre-curing latitude. It permits the pre-cured board to be stored for a long period of time. It is superior in resolution, sensitivity, and solder resistance. Disclosed also herein is a printed circuit board having good adhesion, chemical resistance, electrical properties, gold plating resistance, solder heat resistance, and electrocorrosion resistance. Disclosed also herein is a process for producing said printed circuit board by using said solder resist ink.The photosensitive solder resist ink comprises (A) an ultraviolet-curable resin containing 0-20 wt % of aromatic ring moiety which is obtained by reacting a polymer composed of (a) 40-100 mol % of ethylenically unsaturated monomer having an epoxy group and (b) 0-60 mol % of ethylenically unsaturated monomer capable of copolymerization therewith, with (meth)acrylic acid in an amount of 0.7-1.Type: GrantFiled: May 22, 1996Date of Patent: October 13, 1998Assignee: Goo Chemical Co., Ltd.Inventors: Soichi Hashimoto, Fumito Suzuki, Toshikazu Oda

Patent number: 5582224Abstract: Periphery detectors are arranged along the longitudinal direction of the log which is to be rotated one revolution around a temporary center, thereby a plurality of peripheries of cross sections along the longitudinal direction are detected for the log. The direction of the largest right circular cylinder is determined according to the largest inscribed circles for the peripheries of three cross sections (i.e., the ones adjacent to both the ends of the log and the one in the middle of the log) and the largest right circular cylinder itself is determined according to the peripheries of all cross sections detected. Thus the center line of said largest right circular cylinder is adopted as the turning center. The positions of a pair of inclined beams or swing arms are adjusted for canceling the deviation between the turning center and the temporary center.Type: GrantFiled: September 1, 1995Date of Patent: December 10, 1996Assignee: Kabushikika TaiheiseisakushoInventors: Tetsutaro Mutsuura, Noriyuki Tsukashita, Soichi Hashimoto, Masanori Murakami, Yoshifumi Isogawa, Koichi Oji

Patent number: 5449030Abstract: Periphery detectors are arranged being juxtaposed closely, along the longitudinal direction of the log which is to be rotated one revolution around a virtual center, thereby a plurality of peripheries of cross sections along the longitudinal direction are detected for the log. The direction of the largest right circular cylinder is determined according to the largest inscribed circles for the peripheries of three cross sections (i.e., the ones adjacent to both the ends of the log and the one in the middle of the log) and the largest right circular cylinder itself is determined according to the peripheries of all cross sections detected. Thus the center line of said largest right circular cylinder is adopted as the turning center. The positions of a pair of inclined beams or swing arms are adjusted for canceling the deviation between the turning center and the virtual center.Type: GrantFiled: December 17, 1993Date of Patent: September 12, 1995Assignee: Kabushiki Kaisha TaiheiselsakushoInventors: Tetsutaro Mutsuura, Noriyuki Tsukashita, Soichi Hashimoto, Masanori Murakami, Yoshifumi Isogawa, Koichi Oji
