Publication number: 20240145574Abstract: A manufacturing method of a circuitry including a planar diode that can improve manufacturing precision of a connection between the planar diode and a circuit element connected to an electrode of the planar diode is provided. The manufacturing method of the circuitry including the planar diode includes: forming an insulating layer having a first pattern shape on a substrate; and monolithically forming a functional material layer having a second pattern shape complementary to the first pattern shape on the substrate. The functional material layer includes a material that functions as a planar diode having a rectifying property based on a shape and a size. The second pattern shape has a shape of a circuitry including the planar diode, a first circuit element connected to a first electrode of the planar diode, and a second circuit element connected to a second electrode of the planar diode.Type: ApplicationFiled: March 9, 2022Publication date: May 2, 2024Inventors: Shinji NOZAKI, Kazuo UCHIDA, Minoru FURUKAWA, Yuji TAKEDA

Patent number: 8032287Abstract: A control apparatus for a vehicle that decreases shift shock generated by full engagement of a clutch at completion of an inertia phase. The apparatus includes a driving source, a step automatic transmission arranged to attain a predetermined shift stage by engagement of frictional engagement elements, a rotational speed control to control the driving source so that an input rotational speed of the transmission becomes a predetermined target value during the inertia phase, a torque control to control the driving source so that the input torque of the transmission becomes a predetermined target value during the non-inertia phase, and a torque correction to correct the engagement torque of the engagement element or the input torque of the transmission so that the engagement torque of the engagement element before completion of the inertia phase is substantially identical to the input torque of the transmission after completion of the inertia phase.Type: GrantFiled: March 3, 2008Date of Patent: October 4, 2011Assignee: Nissan Motor Co., Ltd.Inventors: Yuji Nozaki, Shoji Kan

Patent number: 7975791Abstract: A hybrid vehicle drive control system has a first clutch interposed between an engine and a motor/generator, a transmission including several gear position clutches arranged between the motor/generator and a drive wheel, and a controller. The controller selectively starts the engine using torque from the first clutch during a drive mode change from an electric drive mode to a hybrid drive mode. When an engine start command and a gear shifting operation occur during a drive mode change, the controller selects the gear position clutch that is a common engaged clutch from among the engaged gear position clutches constituting the vehicle running gears occurring from immediately before starting the engine until immediately after starting the engine as a second clutch to be controlled. Then, the controller executes a slip control of the second clutch when the first clutch is being connected to start the engine during the drive mode change.Type: GrantFiled: November 8, 2006Date of Patent: July 12, 2011Assignee: Nissan Motor Co., Ltd.Inventors: Yuji Nozaki, Kiminori Nakamura

Patent number: 7770678Abstract: A hybrid vehicle drive control system has a first clutch interposed between an engine and a motor/generator, a transmission including several gear position clutches arranged between the motor/generator and a drive wheel, and a controller. The controller selectively starts the engine using torque from the first clutch during a mode drive change from an electric drive mode to a hybrid drive mode. When an engine start command occurs during the drive mode change, the controller selects the engaged gear position clutch that has the maximum torque transfer capacity from the engaged clutches constituting a vehicle running gear occurring during an engine starting process as a second clutch to be controlled. Then the controller executes a slip control of the second clutch when the first clutch is being connected to start the engine during the mode change from the electric drive mode to the hybrid drive mode.Type: GrantFiled: November 8, 2006Date of Patent: August 10, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Yuji Nozaki, Kiminori Nakamura

Patent number: 6569578Abstract: A method for forming a photo-mask includes forming a light-shielding layer on a substrate, coating a resist film on the light-shielding layer, exposing the resist film with low dosage, and inclining a resist profile after developing the exposed resist film. Accordingly, an opening dimension of the light-shielding layer can be designed without depending on the location of the region with respect to the formed resist pattern of the photo-mask.Type: GrantFiled: March 1, 2001Date of Patent: May 27, 2003Assignee: Oki Electric Industry Co., Ltd.Inventors: Yuji Nozaki, Yasuki Kimura
