Abstract:
A valve timing control device includes a driving rotary element synchronously rotatable with a crankshaft; a driven rotary element mounted coaxially with the driving rotary element and synchronously rotatable with a camshaft; a plurality of partitions provided in the driven rotary element each for dividing a fluid pressure chamber formed between the driving rotary element and the driven rotary element into a regarded angle chamber and an advanced angle chamber; and a connecting element for connecting the driven rotary element to the camshaft. The connecting element includes a flange inserted into a recess formed in the driven rotatory element, and a shaft portion inserted into a through bore formed in a wall of the driving rotary element adjacent to the camshaft. The flange has an outer diameter larger than that of the shaft portion, and is disposed between the driven rotary element and the wall.
Abstract:
A valve timing control apparatus includes a drive-side rotation member synchronously rotating with a crankshaft of an internal combustion engine, a driven-side rotation member integrally rotating with a camshaft, a rotational phase adjusting device including a retarded angle chamber and an advanced angle chamber, the rotational phase adjusting device adjusting the relative rotational phase between the drive-side rotation member and the driven-side rotation member, and a boss member provided at a portion of the driven-side rotation member facing an outer wall surface of the internal combustion engine and including a thrust surface that extends to be perpendicular to a rotational axis of the camshaft and that is exposed to the outer wall surface of the internal combustion engine. The boss member causes the drive-side rotation member to be prevented from making contact with the outer wall surface by making contact with the outer wall surface of the internal combustion engine.

Abstract:
A rear frame attachment structure for a two-wheeled motor vehicle includes a main frame supporting an engine, a pair of right and left center frames extending vertically behind the engine, and a rear frame supporting a seat and a side cover. An end section of the rear frame is attached to the center frame by a fastening member. A concave section of the center frame is formed in an outside surface of the center frame and is attached to the end section of the rear frame. Further, an end section of the side cover extends to a periphery of a head section of the fastening member. The concave section and the end section of the side cover surround the periphery of the head section of the fastening member.

Abstract:
An anti-reflection microstructure including: convex portions arranged at a pitch shorter than a wavelength of visible light, each of the convex portions having a conic shape defined by an apex, a lateral surface, and a base, wherein an intersecting line between the lateral surface and a plane which passes through the apex and is perpendicular to the base, is equivalent to a curve expressed by an nth-order linear formula in which 1
Abstract:
A hot starter cable extends from a hot starter valve and an end of the hot starter cable is connected to a hot starter lever provided in the vicinity of a handle so that the hot starter valve can be opened by operating the hot starter lever. It is possible to easily operate the hot starter lever while the operator always keeping a hold on the handle, so that the operability at the time of restarting the engine can be further enhanced. In addition, since the hot starter lever is present within the visual field of the driver, the hot starter lever can be securely operated.
Abstract:
The invention involves the combination of Interleukin-12 with p53 derived peptides and an adjuvant, preferably QS-21. It is found that this combination provokes a surprisingly strong immune response. Further, in an accepted in vivo model, the use of compositions containing these three ingredients led to diamatic decreases in the growth of induced tumors, thus suggesting a therapeutic regime.
