A cam cylinder is provided with a first group cam and a second group cam, respectively. A first group lens system and a second group lens system are engaged through a first group driving pin and a second group driving pin with the first and second group cams, respectively. The first and second group lens systems are biased by a spring and are placed under a biased force acting in the opposite directions along an optical axis. The first and second group cams have large cam angles in the vicinity of a starting position for collapsing in which a spring force is small, and the cam angles are reduced continuously in response to an increment of the spring force, and the cam angles become minimum in the vicinity of a collapsed position in which the spring force is maximum.

Disclosed here is a control unit employed for an internal combustion engine and provided with air flow sensor output correcting element capable of correcting a detected voltage error to occur in the air flow sensor according to a surge voltage and a supply voltage at each actuation of the thermal type air flow sensor. The thermal type air flow sensor output correcting element includes surge time measuring element for measuring a surge time in a value detected in the thermal type air flow sensor at the time of the sensor power on and supply voltage detecting means. The output correcting element thus calculates a warming-up characteristic correction amount for the thermal type air flow sensor according to the measured surge time and the detected supply voltage.

In fuel injection control apparatus and method for an engine having a variably operated engine valve in which at least a closure timing of an intake valve is variably controlled, a controller determines whether an actual closure timing of the intake valve is in a steady state, calculates a volume of a cylinder calculated from a target control value of the closure timing of the intake valve when determining that the actual closure timing is in the steady state and a fresh-air rate within the cylinder, calculates a mass air quantity sucked into the cylinder on the basis of a mass air quantity within an intake manifold calculated by income and outgo calculations of inflow and outflow quantities of a mass air within the intake manifold and a volume of the manifold, and calculates a fuel injection quantity on the basis of the mass air quantity sucked into the cylinder.

Flat cables 12 are arranged on a plane, and insulating sheaths 11 are fused and connected at ends of the flat cables 12 to form a first fused portion 16. A second fused portion 17 is formed next to the first fused portion 16. Further, the insulating sheaths 11 are fused and connected in intermediate positions of the respective flat cables 12, thereby forming a third fused portion 19. The first fused portion 16 strengthens the connection of a flat multiple-core cable at its opposite ends without fusing and adhering a tape thereto. The second fused portion 17 prevents the flat multiple-core cable from being bent during the insertion into a terminal in an equipment. After the insertion, the second fused portion 17 having a sufficient flexibility permits the flat multiple-core cable to be bent near the opening of the terminal. Further, the third fused portion 19 enables the connection of the respective flat cables in their intermediate positions without the use of a connecting member, thereby reducing a production cost and making the flat multiple-core cable suitable for use in a wiring in a narrow space.

A control system of a hybrid vehicle, includes: an engine; a motor capable of driving the engine; an oil pump for supplying a lubricant oil to a lubrication requiring portion of the engine; and an engine lubrication controller configured to make the following operations in a case that a stop state of the engine continues for more than or equal to a certain period: when a vehicle stop condition that a driver has no intention of travel is established, supplying, by the oil pump, the lubricant oil to the lubrication requiring portion of the engine, and rotating the engine by the motor without igniting the engine, thereby implementing an engine lubrication control.

A drive mechanism includes a rotational cylinder capable of moving upon the optical axis, a cam part on a fixed member and a cam follower which is formed on the rotational cylinder fitting with the cam part and has a conical portion and a cylindrical portion. The cam part includes a tapered cam groove formed such that the cylinder extends in the optical axis upon a range whereupon the cylinder moves from the collapsed state to a photography state and a planar surface formed such that the cylinder does not move upon the optical axis upon the photography range. The conical portion fits with the cam groove of the cam part upon the range whereupon the cylinder moves upon the optical axis, and the cylindrical portion fits with the planar surface of the cam part upon the range whereupon the cylinder does not move upon the optical axis.

A cam locus of the cam surface on the image plane side of the first group cam groove of the rotating cylinder has an angle to a flat surface where the optical axis crosses perpendicularly. When the cam follower engages with the cam surface on the image plane side, an impact force is dispersed into the optical axis direction and the rotating direction of the rotating cylinder, and a load on the cam follower and male helicoid is reduced. When the first group lens system is pressed by a light load, the cam follower of the first group lens movement frame engages with the cam surface on the image plane side, and an angle of the cam surface is equal to an angle of a force occurring in the rotating direction. Therefore, the rotating cylinder does not rotate easily, and returns to its previous position when the load is removed.

A lens barrel includes a plurality of lens groups (1, 2), lens frames (1a, 2a) to hold the plurality of lens groups, respectively, a lens driving apparatus to drive the plurality of lens frames and a fixed member (5) to hold the lens driving apparatus. The lens driving group includes a rotational member (6) which is forwardly moved while rotating relative to the fixed member (5), a linearly moving guide member (7) which moves with the rotational member (6) in the optical axial direction while limiting rotation of the lens frames and is not capable of rotating, and a linearly moving-guide biasing member (8) which is capable of moving in the optical axial direction relative to the linearly moving guide member and is configured to limit rotation. The linearly moving-guide biasing member has a resilient structure configured to bias the linearly moving guide member in the optical axial direction.
