Publication number: 20140277890Abstract: 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: ApplicationFiled: September 6, 2011Publication date: September 18, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yukihiko Ideshio, Susumu Kojima, Naoki Nakanishi, Akihiro Sato

Publication number: 20140267462Abstract: A first sample holding unit (22) samples and holds subframe data on a column data line (D) inputted via a first switching unit (21) when a pixel (20) is selected by a row selection signal applied via a row selection line (W). After the subframe data is held by the first sample holding units (22) of all pixels, a second sample holding unit (24) samples and holds the subframe data inputted through a second switching unit (23) activated by a common signal to apply the subframe data to a pixel electrode (12) of a liquid crystal element (LC). Consequently, a voltage selection unit between the second sample holding unit (24) and the pixel electrode (12) becomes unnecessary as well as subframe data can be transferred without a suspension period of the subframe data.Type: ApplicationFiled: May 28, 2014Publication date: September 18, 2014Applicant: JVC KENWOOD CorporationInventor: Akihiro Sato
