Abstract: A control device comprises: a temperature estimating unit for estimating the temperature of a piston of an internal combustion engine of a vehicle; and a control unit which, if the temperature of the piston estimated by the temperature estimating unit has risen to a first threshold corresponding to a heat resisting temperature of the piston, reduces an upper limit value of a fuel injection timing at which a fuel injector for injecting fuel onto the piston injects the fuel, and which increases the upper limit value of the fuel injection timing at a higher temperature than the first threshold when the rise in temperature of the piston stops.

Abstract: An electric drive device includes: an electronic control section including a first electronic control section and a second electronic control section which constitute a redundant system, the first electronic control section and the second electronic control section being provided with a first control section side connecter and a second control section side connecter which have an identical configuration, and the first non-control section side connecter being engaged with the first control section side connecter, and the second non-control section side connecter being engaged with the second control section side connecter to correspond to the lengths of the first harness and the second harness.

Abstract: When sucking a fluid within a body cavity, foreign matter included in the fluid which exceeds the filtering diameter of a filtering apparatus may cause clogging of the filtering apparatus. Another concern is that a body cavity membrane getting stuck to a suction port of a suction tube may lead to the suction port being closed off. In response to such problems as these, provided is a suction apparatus, comprising a suction tube, and a filter member. The suction tube has side holes formed in a tube wall on a body cavity-side tail end part. The filter member has a tubular cap shape and covers a tail end aperture of the suction tube and the side holes, is formed from a foam body with an average aperture opening of 500-1000 ?m, and has a thickness of 7.5 mm or more.

Abstract: The present invention provides an operation field-securing device that secures an operation field by being deployed within the body cavity. The operation field-securing device includes at least three elongated parts extending radially in a deployed state; and curved parts, the number of which is the same as that of the elongated parts. Each pair of the two adjacent elongated parts is connected at their one ends by the curved part. Each of the curved parts is convex toward a side opposite to the elongated part. In the deployed state, the curved parts are arranged circumferentially. By deforming the curved parts, the operation field-securing device is capable of being brought into either one of a contracted state where a distance between the adjacent elongated parts is shortened by making the elongated parts close to each other and the deployed state where the distance between the elongated parts is expanded.
