Patent number: 9957905Abstract: An engine system includes an internal combustion engine, a forced induction device, an ejector device, a blow-by gas passage, and a controller. The ejector device has an ejector and a drive gas passage connected to an intake passage of the engine in a manner bypassing a compressor of the forced induction device. The controller is adapted to execute a temperature raising control when the controller determines that condensate water is likely to freeze in the ejector device. In the temperature raising control, the controller raises intake air pressure in a downstream portion of the intake passage with respect to the compressor compared to when the controller determines that the condensate water is unlikely to freeze and adjusts an intake air amount of the engine to restrain increase of the intake air amount that would be caused by increase in the intake air pressure.Type: GrantFiled: February 19, 2015Date of Patent: May 1, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Masaki Makihara

Patent number: 9739237Abstract: An exhaust gas recirculation device for an engine including a plurality of cylinders and intake branch passages is provided. The exhaust gas recirculation device includes an exhaust chamber and distribution passages for the respective cylinders. The exhaust chamber is connected to an exhaust passage of the engine, and exhaust gas from the exhaust passage is introduced into the exhaust chamber. The distribution passages connect the exhaust chamber to the intake branch passages for the respective cylinders so as to recirculate the exhaust gas back into the intake branch passages. The flow passage area of a first portion of each of the distribution passages is smaller than the flow passage area of a second portion of each of the distribution passages. The first portion is connected to the corresponding intake branch passage, and the second portion is connected to the exhaust chamber.Type: GrantFiled: May 18, 2015Date of Patent: August 22, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Taketo Nagasaki, Yoshihiro Miyaji, Masaki Makihara

Patent number: 6452140Abstract: A substance 6 is located in a gradient magnetic field and held in a levitating state by a magnetic force produced by the gradient magnetic field. The substance 6 as such in the levitating state is heated and melted by ray or heat irradiation or by a resistance heater. Thereafter, the heating is stopped, and the substance 6 is cooled as such in the levitating state. Since the magnetic force realizes the microgravity field where the substance 6 is melted and cooled in the levitating state, the substance 6 is formed to an ideally spherical shape with an extremely smooth surface.Type: GrantFiled: March 14, 2001Date of Patent: September 17, 2002Assignees: Japan Science and Technology Corporation, Japan as Represented by Director-General of National Institute of Advanced Industrial Science and Technology, Ministry of Economy, Trade and IndustryInventors: Mitsuhiro Motokawa, Kazuo Watanabe, Satoshi Awaji, Iwao Mogi, Naoyuki Kitamura, Masaki Makihara
