Abstract: According to an aspect, a display apparatus includes: a substrate; a plurality of pixels arrayed on the substrate; a plurality of inorganic light-emitting elements that are provided in the pixels, respectively; a transistor provided to a first surface of the substrate and coupled to one of the inorganic light-emitting elements; wiring provided to the first surface of the substrate and coupled to the transistor; and a circular polarization plate provided on a first side of the substrate.

Abstract: In an engine such as an engine for driving a pump or dynamo, in which a load increasing state does not appear as an accelerating state of rotation speed, it is intended to prevent the smoke emission in an abruptly load-increasing state, which might otherwise be caused by the suppression or interruption of an EGR quantity. The engine 10 comprises a supercharger 11 and an exhaust gas recirculation (EGR) device 12. The engine 10 makes an isochronous control or a droop control, when its rotation speed N is shifted from a no-load (idle) or light-load run to a high-load (load-increasing) state. In case it is detected, when the state of the engine 10 shifts to a load state, that the actual rotation speed N becomes lower by a predetermined rotation speed ?N than a target rotation speed Nm, an EGR valve 13 of the exhaust gas recirculation (EGR) device 12 is either throttled to an opening smaller by a predetermined opening ?F than the ordinary set opening F corresponding to the load state or fully closed.

Abstract: A breather device comprises a breather chamber (22) provided in a valve arm chamber (2) arranged above a cylinder head of an engine. In the breather chamber, blow-by gas including oil mist is separated into oil component and gas component, and the oil mist is removed from the blow-by gas. The interior of the breather chamber is alternately divided into plural horizontally juxtaposed rooms (22a, 22b, 22c) by a partition (23) extended from a bottom surface of the breather chamber and a partition (2a) extended from a ceiling surface of the breather chamber. Plural oil trap members (10) for trapping oil mist in the blow-by gas are arranged in the breather chamber. Especially, the oil trap member arranged at a blow-by gas inlet of the breather chamber is held by a holder (11) made separately from members (2, 7) forming the valve arm chamber (5).
