GAS LASER AMPLIFIER, GAS LASER APPARATUS, EUV LIGHT GENERATION APPARATUS, AND EUV EXPOSURE APPARATUS
Publication number: 20240128705Abstract: A gas laser amplifier includes a housing, discharge electrode pairs, and an optical resonator. The housing includes an entrance window that allows entry of a first laser beam from outside and an exit window that allows exit of the first laser beam amplified. Each of the discharge electrode pairs excites a laser gas supplied between discharge electrodes facing each other in the housing. The optical resonator causes a second laser beam to oscillate with a gain of the excited laser gas in a non-incident state where the first laser beam from outside the housing does not enter the housing through the entrance window. In an incident state where the first laser beam enters the housing through the entrance window, the optical resonator suspends the oscillation of the second laser beam.Type: ApplicationFiled: November 11, 2019Publication date: April 18, 2024Applicant: Mitsubishi Electric CorporationInventors: Tatsuya YAMAMOTO, Junichi NISHIMAE, Yuzuru TADOKORO, Masashi NARUSE, Takuya KAWASHIMA -

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: 7340886Abstract: A diesel engine (1) comprises an exhaust passage (3), and a DPM filter (4) provided on the exhaust passage (3), which traps diesel particulate matter (DPM) contained in the exhaust gas such that the diesel particulate matter accumulates therein. An engine controller (11) starts regeneration processing of the DPM filter (4) by raising the exhaust gas temperature when a regeneration timing of the DPM filter (4) is reached, sets a target exhaust gas temperature during regeneration processing to ensure that the temperature of the DPM filter (4) does not exceed an upper temperature limit of the DPM filter (4), even when the temperature of the DPM filter (4) is raised due to the engine (1) entering an idling condition during the regeneration processing, and controls the exhaust gas temperature to the target exhaust gas temperature.Type: GrantFiled: September 7, 2004Date of Patent: March 11, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Junichi Kawashima, Naoya Tsutsumoto, Makoto Otake, Terunori Kondou, Takao Inoue, Shouichirou Ueno, 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: 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: 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: 7219493Abstract: A regeneration control device which regenerates a filter (13) by increasing an exhaust gas temperature to burn exhaust gas particulates trapped in the filter, is disclosed. The filter (13) traps particulate matter in exhaust gas from an engine (1). The regeneration control device suppresses fuel cost-performance impairment due to filter regeneration. The regeneration control device has a load detection sensor (31) which detects an engine load and a microcomputer-based controller (22).Type: GrantFiled: September 10, 2004Date of Patent: May 22, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Naoya Tsutsumoto, Junichi Kawashima, Makoto Otake, Terunori Kondou, Takao Inoue, Toshimasa Koga, Shouichirou Ueno

Patent number: 7200991Abstract: A filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20) for a vehicle is regenerated by fuel injection control. A controller (16) calculates a representative value of the operating condition of the diesel engine (20) during a latest predetermined time period, and determines the traveling condition of the vehicle on the basis of this representative value. When the representative value corresponds to a highway traveling condition, fuel injection control is performed in accordance with a pattern for burning all of the particulate matter trapped in the filter (10). Under any other conditions, fuel injection control is performed in accordance with another pattern. Hence optimum filter regeneration can be performed depending on the traveling condition of the vehicle.Type: GrantFiled: September 7, 2004Date of Patent: April 10, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Makoto Otake, Junichi Kawashima, Naoya Tsutsumoto, Terunori Kondou, Takao Inoue, Shouichirou Ueno, Toshimasa Koga
