In a vane type valve timing control apparatus, when an amplitude of a rotation phase of a cam shaft with respect to a crank shaft is above a predetermined value, a target value for the rotation phase is forcibly changed to a maximum advance angle and a maximum delay angle, so that oil of an advance
In a vane type valve timing control apparatus, when an amplitude of a rotation phase of a cam shaft with respect to a crank shaft is above a predetermined value, a target value for the rotation phase is forcibly changed to a maximum advance angle and a maximum delay angle, so that oil of an advance angle side hydraulic chamber and a delay angle side hydraulic chamber is discharged together with air.

The hybrid hull as defined in claim 15, wherein said plate means extends laterally from the collars in contact with the transition extensions of the bow and stern sections. 17. The hybrid hull as defined in claim 16, wherein said transition extensions of the midship section include hat-shaped portions abutting rib portions of the transition extensions of the bow and stem sections. 18. A hybrid hull of a marine vessel having a midship section from which bow and stern sections extend in opposite directions, wherein each of said hull sections has a reinforced structure with the structure of the midship section being made of a different material from that of the bow and stern sections, including: transition extensions between the hull sections establishing geometric compatibility therebetween and an arrangement for interconnection of the hull sections, comprising: plate means extending from the transition extensions; and holding means carried by said plate means for attaching the hulls sections to each other; said transition extensions establishing a flush cross-sectional relation between the structures of adjacent hull sections; said midship section being made of reinforced metal and the bow and stern sections being made of reinforced non-metallic material; said plate means including: inserts interfitted between the transition extensions and secured thereto by the holding means, said holding means carried by the plate means, including: a plurality of threadedly inserted bolts extending through the transition extensions, and collars in overlapping contact with the transition extensions through which the bolts extend. 19. The hybrid hull as defined in claim 18, wherein said plate means extends laterally from the collars in contact with the transition extensions of the bow and stern sections through which the bolts extend. 20. The hybrid hull as defined in claim 19, wherein the transition extensions of the midship hull section has hat-shaped portions which abut rib portions of the transition extensions of the bow and stem hull sections. 21. A hybrid hull of a marine vessel having a midship section from which bow and stem sections extend in opposite directions, wherein each of said hull sections has a reinforced structure with the structure of the midship section being made of a different material from that of the bow and stern sections, including: transition extensions between the hull sections establishing geometric compatibility therebetween and an arrangement for interconnection of the hull sections, comprising: plate means extending from the transition extensions; and holding means carried by said plate means for attaching the hulls sections to each other, the structure of the midship section being metallic and reinforced by cross-sectionally T-shaped ribs, the struct ure of the bow and stem hull sections being non-metallic and reinforced by cross-sectionally hat-shaped ribs, and the transition extensions of the midship section being the T-shaped ribs transitioned into hat-stiffened ribs to establish the geometric compatibility. 22. A hybrid hull of a marine vessel having a midship section from which bow and stem sections extend in opposite directions, wherein each of said hull sections has a reinforced structure with the structure of the midship section being made of a different material from that of the bow and stem sections, including: transition extensions between the hull sections establishing geometric compatibility therebetween and an arrangement for interconnection of the hull sections, comprising: plate means extending from the transition extensions; and holding means carried by said plate means for attaching the hull sections to each other, the structure of the midship section being metallic and reinforced by cross-sectionally the T-shaped ribs transitioned into hat-stiffened rib construction to form the transition extensions, while the bow and stem sections are of non-metallic sandwich construction transitioned by said hat-stiffened construction of the transition extensions to establish geometric compatibility. 23. A hybrid hull of a marine vessel having a midship section from which bow and stem sections extend in opposite directions, wherein each of said hull sections has a reinforced structure with the structure of the midship section being made of a different material from that of the bow and stem sections, including: transition extensions between the hull sections establishing geometric compatibility therebetween and an arrangement for interconnection of the hull sections, comprising: plate means extending from the transition extensions; and holding means carried by said plate means for attaching the hull sections to each other, the structure of the midship section being of metallic double hull sandwich construction, and the structure of the bow and stern sections is transitioned by hat-stiffened construction of the transition extensions to establish the geometric compatibility, while the structure of the bow and stern sections are non-metallic and reinforced by cross-sectionally hat-shaped ribs. 24. A hybrid hull of a marine vessel having a midship section from which bow and stern sections extend in opposite directions, wherein each of said hull sections has a reinforced structure with the structure of the midship section being made of a different material from that of the bow and stern sections, including: transition extensions between the hull sections establishing geometric compatibility therebetween and an arrangement for interconnection of the hull sections, comprising: plate means extending from the transition extensions; and holding means carried by said plate means for attaching the hull sections to each other, the structure of the midship section being of metallic double hull sandwich construction transitioned by hat-stiffened construction of the transition extensions, while the bow and stern sections are of non-metallic sandwich construction transitioned by hat-stiffened construction of the transition extensions to establish the geometric compatibility. ting point; as compared to the second connecting point, the first connecting point is selected as the actual connecting point.
