Color converting member, method of manufacturing the same, light emitting device, and display device
Patent number: 9001288Abstract: A color converting member is capable of suppressing deterioration in a phosphor by a simple manufacturing process. A method of manufacturing a color converting member includes a process of molding a resin material into a shape. In the process, molding the resin material and the phosphor integrally into a shape is performed, after kneading a phosphor that converts one color light to another color light into the resin material.Type: GrantFiled: January 20, 2010Date of Patent: April 7, 2015Assignee: Dexerials CorporationInventors: Tsubasa Tsukahara, Yasushi Ito, Naoji Nada, Yoshihiro Oshima, Hideya Chubachi -
Patent number: 9002619Abstract: It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine includes an impulse valve common to all the cylinders arranged in the engine. The impulse valve is arranged in a communicating tube provided at the downstream side of a serge tank. An ECU executes impulse valve drive control. In the control, the ECU judges whether a rotation angle sensor which detects the open degree of the impulse valve has failed. If it is judged that the rotation angle sensor has failed, the ECU controls a drive motor and a drive circuit for driving a valve body so that a valve body of the impulse valve rotates inside the communicating tube. Here, the rotor of the drive motor which defines the rotation speed of the valve body has an rpm which is set in accordance with the mechanical rpm NE of the engine.Type: GrantFiled: November 28, 2008Date of Patent: April 7, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasushi Ito, Shouji Katsumata, Keiji Yoeda, Hideyuki Nishida, Shiro Tanno

Patent number: 8904994Abstract: An ammonia burning internal combustion engine can feed ammonia and a highly combustible substance burning easier than ammonia to a combustion chamber. When the amount of ammonia fed into the combustion chamber is increased or when the ratio of the amount of the ammonia to the total amount of the ammonia and the highly combustible substance fed into the combustion chamber is increased, the operating parameters of the internal combustion engine are controlled so the air-fuel mixture fed into the combustion chamber is made easier to burn. As a result, an ammonia burning internal combustion engine designed to suppress a drop in combustibility of auxiliary fuel due to ammonia, can be provided.Type: GrantFiled: April 26, 2010Date of Patent: December 9, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryo Michikawauchi, Yasushi Ito, Kazuki Iwatani, Shiro Tanno

Patent number: 8720417Abstract: An internal combustion engine can use ammonia and a non-ammonia fuel which is easier to burn than ammonia as fuel. The non-ammonia fuel is directly injected into a combustion chamber by a non-ammonia fuel injector, and the injected non-ammonia fuel is ignited, whereby combustion of the air-fuel mixture in the combustion chamber is commenced. In the control system of the internal combustion engine, the injection timing of the non-ammonia fuel is advanced at a time when a ratio of ammonia in all fuel fed to the internal combustion engine is high in comparison with the time when the ratio is low. Therefore, a control system of an internal combustion engine capable of using ammonia and a non-ammonia fuel (gasoline, light oil, hydrogen, etc.) which is easier to burn than ammonia, which suitably feeds fuel and controls combustion in order to suitably burn an air-fuel mixture in a combustion chamber is provided.Type: GrantFiled: May 1, 2013Date of Patent: May 13, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazuki Iwatani, Yasushi Ito, Shiro Tanno

Publication number: 20130248359Abstract: Disclosed is a mixed gas generating device and has an object to provide a mixed gas generating device capable of generating CO and H2 with favorable energy efficiency. An energy efficiency characteristic line 10 of electrolysis with respect to a generation ratio between CO and H2 (CO/H2) becomes a curve projecting downward. Thus, electrolysis is executed not at an operation point A where CO/H2=1/2 is given but in a divided manner at an operation point B and an operation point C. However, the electrolysis time is divided into electrolysis time periods such that the generation ratio of a mixed gas becomes CO/H2=1/2 after the electrolysis is executed with the respective generation ratios. As a result, energy efficiency in the vicinity of an operation point D higher than the operation point A can be obtained.Type: ApplicationFiled: December 8, 2010Publication date: September 26, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yasushi Ito
