Patent number: 9165530Abstract: A signal processor converts an input 3D image signal into a signal in which a left-eye signal and right-eye signal are rearranged temporally alternately. A driver of a liquid crystal display element includes a sub-frame data generator configuring all the sub-frames with step bit pulses and generating sub-frame data by using a drive gradation table in which the last sub-frame reaches a drive state when a drive gradation is “1” and the number of sub-frames reaching the drive state is increased one by one toward ahead of a sub-frame which has already reached the drive state, every time the drive gradation is increased by one. The liquid crystal display element is driven by the driver. An illumination optical system causes illumination light to enter into the liquid crystal display element. A projection lens projects modulated light emitted from the liquid crystal display element.Type: GrantFiled: May 7, 2013Date of Patent: October 20, 2015Assignee: JVC Kenwood CorporationInventors: Naoya Okamoto, Hiroyuki Takada, Takeshi Makabe, Akihiro Sato

Patent number: 9156468Abstract: Provided is a control device for a hybrid vehicle capable of attaining an assist torque generated by a clutch mechanism at an appropriate timing, upon starting the engine. Since an electronic control device outputs an engagement command for engaging a clutch (clutch mechanism) at a time preceding an (ignition) start command time for igniting an engine by a preceding-sending time, the clutch becomes engaged when the engine speed starts to increase, and the assist torque generated by the clutch mechanism can thus be obtained at an appropriate timing. Because the engine speed that was once increased upon starting the engine is not decreased, the energy that was consumed for starting the engine can be effectively used.Type: GrantFiled: September 6, 2011Date of Patent: October 13, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yukihiko Ideshio, Susumu Kojima, Naoki Nakanishi, Akihiro Sato

Publication number: 20150283994Abstract: A control apparatus is applied to a hybrid vehicle having a driving apparatus including a power split mechanism which splits torque of an internal combustion engine into a first MG and output portion, and a motor lock mechanism which switches a state of the power split mechanism between a differential state in which the torque of the internal combustion engine splits into the first MG and output portion and a non-differential state in which it is stopped to split the torque. The hybrid vehicle switches a driving mode between a first driving mode in which the power split mechanism is switched to the differential state and a second driving mode in which the power split mechanism is switched to the non-differential state. The control apparatus calculates energy loss of the driving apparatus in each driving mode, and switches the driving mode of the vehicle based on the calculated energy loss.Type: ApplicationFiled: December 18, 2012Publication date: October 8, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryo Matsumoto, Hiroatsu Endo, Tetsuo Hori, Akihiro Sato
