Patent number: 7311637Abstract: In an automatic transmission control system, an operating amount of a throttle due to a driver's depression of an accelerator pedal is detected, and the rotating number of an engine suitable for the detected throttle operating amount is detected. The automatic transmission control system includes a shift map defined by the throttle operating amount and the engine rotating number. The actuation of upshift or downshift of a transmission is automatically controlled based on the shift map. The driver can be informed of a point where a shift map is switched by a depression operation of the accelerator pedal so that generation of unnecessary downshift and delay of upshift are prevented to allow a vehicle to be efficiently driven.Type: GrantFiled: September 27, 2005Date of Patent: December 25, 2007Assignee: Nissan Diesel Motor Co., Ltd.Inventors: Toshio Kitamura, Yuuichi Ichikawa, Akihisa Hayashi, Isao Okamoto, Osamu Isobe

Patent number: 7261673Abstract: In an automatic transmission having a clutch and a gear type transmission, a control unit for inputting detected signals from the operating condition detecting device, and outputting control signals to the gear changing device and the clutch drive device based on the detected signals. The control unit determines whether a stop intention condition of a driver is satisfied or not, and performs first gear change control for, if the stop intention condition is determined to be satisfied, disengaging the friction clutch and changing the gear type transmission to a neutral position, and second gear change control for, when an accelerator opening becomes greater than or equal to a predetermined value, after the friction clutch is disengaged and the gear type transmission is changed to the neutral position by the first gear change by the first gear change control, changing the gear type transmission to a gear according to a vehicle speed, and engaging the friction clutch.Type: GrantFiled: October 21, 2003Date of Patent: August 28, 2007Assignee: Nissan Diesel Motor Co., Ltd.Inventors: Toshio Kitamura, Yuuichi Ichikawa, Akihisa Hayashi, Isao Okamoto, Osamu Isobe

Patent number: 6623296Abstract: A plug socket includes an intermediate plug having an intermediate slit into which a terminal blade of an insertion plug is inserted and an intermediate terminal blade, a case part containing a main terminal blade-receiving element into which the intermediate terminal blade is inserted, and a mounting element for securing the case part onto a wall surface. The mounting element includes a recessed portion as a housing space for the intermediate plug, and a main slit is provided at the bottom face of the recessed portion for inserting the intermediate terminal blade. Accordingly, the intermediate plug arranged within the recessed portion is interposed to connect the insertion plug with the main terminal blade-receiving element. Therefore, such a socket can be provided that prevents breakage of the terminal blade-receiving element of the socket due to frequent insertion/removal of the insertion plug and allows for easy repair even if broken.Type: GrantFiled: May 3, 2002Date of Patent: September 23, 2003Assignee: Nichido Kogyo Kabushiki KaishaInventor: Isao Okamoto
