Abstract: Provided is a vehicle front structure capable of, without breaking a lid provided at a thermal insulating cover, reliably closing a bonnet and the lid even if an attempt is made to close the bonnet prior to closing the lid. In the present invention, a thermal insulating cover 10 including a lid 30 that covers the upper side of an engine in an openable and closable manner is provided below a bonnet 1 that covers the upper side of an engine room in an openable and closable manner; the lid 30 is provided with, in the vehicle front-rear direction, a hinge fulcrum 36 on the same rear end side as a hinge fulcrum 4 of the bonnet 1 and is openable and closable independently of the bonnet 1; and the lid 30 includes locking means 40 that is locked to the bonnet 1 when the lid 30 is open and is released from the locking in conjunction with a closing operation of the bonnet 1.

Abstract: A vehicle front structure includes, below a bonnet (6), a cover member (1) that covers an engine from an upper portion thereof to the side and is formed by an upper wall (30), a shroud (8) as a front wall, a rear wall (13), and side walls (11, 12) on the respective left and right sides. The cover member is formed by the upper wall, the front wall, the rear wall, and the side walls on the respective left and right sides. The front side of one of the left and right side walls is configured to have, relative to the rear side, a higher ratio of a low-rigidity member having lower rigidity than a high-rigidity member forming a main portion on the rear side.

Abstract: The present invention relates to a process for producing a substance, which comprises culturing an animal cell having an ability to produce the substance in a medium containing a ubiquinone such as Q10 until the substance is produced and accumulated in the culture, and recovering the substance therefrom, and a method of improving the productivity of a substance, which comprises culturing an animal cell having an ability to produce the substance in a medium containing a ubiquinone.

Abstract: An intake system for an engine allows supercharging using the dynamic effect of intake air has a surge tank for a cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a second surge tank for another cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a first upstream intake passage for supplying intake air to the first surge tank, a second upstream intake passage for supplying intake air to the second surge tank, a connecting tank for communicating intermediate portions of the individual intake passages with each other, and a short connecting passage for communicating upstream portions of the first upstream intake passage and the second upstream intake passage with the connecting tank 9.

Abstract: Each surge tank disposed over the respective cylinder head of the combustion engine is connected to the intake port of each cylinder of the combustion engine individually and independently through the independent intake passages. The independent intake passages form a space, i.e. a dead space, in association with the surge tank and the cylinder head, and a first volume chamber or a second volume chamber is disposed within the space in order to provide the dynamic effect of intake air. The dynamic effect of intake air is achieved at least either of resonance supercharging or inertia supercharging.

Abstract: A fuel intake system for a combustion engine of a type having V-shaped first and second cylinder banks and also having a crank axis of the crankshaft, which comprises a throttle casing disposed in a center space delimited between the first and second cylinder banks, elongated first and second surge tanks extending in a direction parallel to the crank axis and disposed on respective sides of the center space, and a passage system communicating the throttle casing to each of the first and second surge tanks. The passage system comprises a merging region communicated with the throttle casing and first and second branch ducts branched off from one end of the merging region opposite to the throttle casing. The first and second branch ducts connect to the first and second surge tanks, respectively. Each of the first and second branch ducts is comprised of two independent passages spaced apart from each other in a direction parallel to the crank axis.
