Patent number: 11216032Abstract: An information reading apparatus that is easy for a user to operate even if different functions are required for each situation is provided. A base module includes a control unit which performs control by using three functional modules assembled thereto, that is, a top module, a bottom module, and a back module, and a touch panel whose display content is controlled by the control unit. The top module is connected to a one end of the base module in the longitudinal direction, the bottom module is connected to the other end of the base module in the longitudinal direction, and the back module is connected to a rear side of the base module, which faces away from a display screen of a touch panel. The control unit recognizes each function on the basis of the information obtained from the three functional modules connected to the base module.Type: GrantFiled: April 26, 2019Date of Patent: January 4, 2022Assignee: DENSO WAVE INCORPORATEDInventors: Takao Ushijima, Makoto Ootake, Keiichiro Yamamoto, Masaru Hashimoto, Katsunori Sakakibara

Patent number: 7343738Abstract: An engine controller (20) controls regeneration of a diesel particulate filter (11) deployed along an exhaust passage (3) of a vehicle diesel engine (9). Regeneration terminates in response to a terminating request based on running conditions of the diesel engine (1). When the regeneration elapsed time at the time of termination is shorter than a reference duration, the engine controller (20) adds a time corresponding to a deviation of the regeneration elapsed time from the reference duration to the reference duration for the next regeneration of the DPF (11), thereby completely removing particulate matter accumulated in and around an inlet (18) of the filter (11).Type: GrantFiled: June 30, 2005Date of Patent: March 18, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Naoya Tsutsumoto, Junichi Kawashima, Masahiko Nakano, Makoto Ootake, Shouichirou Ueno, Terunori Kondou, Toshimasa Koga

Patent number: 7322184Abstract: A particulate matter deposit amount in a diesel particulate filter (4) provided in an exhaust passage (3) of a diesel engine (1) for a vehicle is estimated on the basis of a pressure loss in the filter (4), which is detected by a differential pressure sensor (12). When the temperature of the differential pressure sensor (12) is not within a predetermined temperature range, estimation of the particulate matter deposit amount based on the pressure loss is restricted, and instead, the particulate matter deposit amount is estimated by accumulating a particulate matter deposit amount per unit time. In so doing, increases in the estimation error outside of the predetermined temperature range are prevented. Moreover, by applying these estimation methods selectively in accordance with the vehicle speed, the precision with which the particulate matter deposit amount is estimated outside of the predetermined temperature range is improved.Type: GrantFiled: August 5, 2005Date of Patent: January 29, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Terunori Kondou, Junichi Kawashima, Naoya Tsutsumoto, Makoto Ootake, Shouichirou Ueno, Masahiko Nakano, Toshimasa Koga

Patent number: 7322185Abstract: A particulate matter deposit amount accumulated in a diesel particulate filter (4) is calculated as a first particulate matter deposit amount from a pressure loss of the filter (4) (S33). The particulate matter deposit amount accumulated in the filter (4) is calculated as a second particulate matter deposit amount from another parameter (S34). It is determined whether or not there is front end blockage of the filter (4) based on a comparison between the first particulate matter deposit amount and second particulate matter deposit amount (S36, S43). When there is a front end blockage of the filter (4), the regeneration device is controlled to perform regeneration of the filter (4) for a longer period than the normal regeneration period of the filter (4) (S22).Type: GrantFiled: August 24, 2005Date of Patent: January 29, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Toshimasa Koga, Junichi Kawashima, Makoto Ootake, Masahiko Nakano, Terunori Kondou, Shouichirou Ueno, Naoya Tsutsumoto

Patent number: 7237379Abstract: A particulate filter (41) which traps particulate matter in the exhaust gas of a diesel engine (1), regenerates when a controller (31) performs an exhaust gas increase operation which includes decreasing the opening of an intake throttle (42). The controller (31), during regeneration of the filter (41), determines whether or not the required load of the diesel engine (1) is increasing from an accelerator pedal depression sensor (32) or a fuel injection amount (S3), and prevents output decrease of the diesel engine (1) by interrupting the exhaust gas temperature increase operation when the required load is increasing (S5).Type: GrantFiled: March 11, 2005Date of Patent: July 3, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Masahiko Nakano, Junichi Kawashima, Naoya Tsutsumoto, Makoto Ootake, Terunori Kondo, Shouichirou Ueno, Toshimasa Koga

Patent number: 7159392Abstract: This invention relates to estimation of a particulate matter deposit amount in a diesel particulate filter (1) provided in an exhaust passage (7) of a vehicle diesel engine (10). When the vehicle speed exceeds a predetermined vehicle speed, a differential pressure method, in which the particulate matter deposit amount is estimated based on the differential pressure upstream and downstream of the filter (1), is applied, and when the vehicle speed does not exceed the predetermined vehicle speed, an accumulation method, in which the particulate matter deposit amount is estimated by accumulating an increment determined from the load and rotation speed of the diesel engine (10), is applied. When switching from the differential pressure method to the accumulation method, the particulate matter deposit amount determined in the differential pressure method is used as an initial value of the accumulation, and thus the particulate matter deposit amount can be determined accurately.Type: GrantFiled: August 10, 2005Date of Patent: January 9, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Terunori Kondoh, Junichi Kawashima, Makoto Ootake, Masahiko Nakano, Shouichirou Ueno, Naoya Tsutsumoto, Toshimasa Koga

Patent number: 6843055Abstract: An oxidation promoting catalyst (42) which converts nitrogen monoxide in exhaust gas to nitrogen dioxide, and a diesel particulate filter (41) which traps soot in the exhaust gas, are installed in an exhaust gas passage of a diesel engine (1). A control unit (21) determines whether or not it is necessary to regenerate the filter based on the exhaust gas pressure detected by an exhaust gas pressure sensor (24), and when it is necessary to regenerate the filter, it increases the nitrogen monoxide in the exhaust gas by performing an advance correction of the fuel injection timing of a fuel injector (14) so as to promote generation of nitrogen dioxide by the oxidation promoting catalyst. The nitrogen dioxide decreases the combustion temperature of the soot trapped by the diesel particulate filter (41), and efficiently regenerates the filter.Type: GrantFiled: May 3, 2002Date of Patent: January 18, 2005Assignee: Nissan Motor Co., Ltd.Inventor: Makoto Ootake

Patent number: 6698192Abstract: A particulate filter (4) is provided in an exhaust passage (3) of a diesel engine (1) in order to trap particulate matter in exhaust gas. A controller (11) determines a basic fuel injection amount in response to an accelerator pedal depression amount (S22), determines a maximum fuel injection amount in response to an intake air amount of the engine (1) (S10), and sets the smaller of the basic fuel injection amount and the maximum fuel injection amount as the target injection amount (S24-S26). When the deposited amount of particulate matter on the particulate matter filter (4) has exceeded a predetermined amount, reductions in output torque are prevented by increasing the maximum injection amount (S13).Type: GrantFiled: November 26, 2002Date of Patent: March 2, 2004Assignee: Nissan Motor Co., Ltd.Inventor: Makoto Ootake
