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.

A cylinder intake air mass quantity for an engine is calculated in accordance with the cylinder intake air volume quantity, the manifold air mass quantity and a manifold volume. The cylinder intake air volume quantity is calculated in accordance with a cylinder volume at an intake valve closing timing. The manifold air mass quantity is calculated from a balance between an intake manifold inflow air mass quantity and an intake manifold outflow air mass quantity. The manifold inflow air mass quantity Qa·&Dgr;t is reset to a minimum setting value when an engine stop state with no intake air induction is detected.

A net-shaped protective material for wire harness sheathing which has flame retardancy and is free from mesh deformation. Vertical strands (2) and horizontal strands (3) which are constituted of a flame-retardant resin wire having an elliptic sectional shape have been pressed and hot melt bonded at the intersections (4) thereof to form a net shape. The vertical strands and horizontal strands are superposed at the intersections without interlacing, and one or both of the vertical strands and horizontal strands are melted in a state where 40% to 50% of the sectional area has been melted and embedded in the other strands. The protective metal has a cut end which has undergone fraying prevention processing.
摘要:
A cam locus of the cam surface (G1) on the image plane side of the first group cam groove (27) of the rotating cylinder (21) has an angle to a flat surface where the optical axis crosses perpendicularly. In a case in which the cam follower (25) engages with (abuts on) the cam surface (G1) on the image plane side, an impact force is dispersed into the optical axis direction and into the rotating direction of the rotating cylinder (21), and a load which the cam follower (25) and the male helicoid (31) of the rotating cylinder (21) receive is reduced. Additionally, when the first group lens system (11) is pressed by a light load such as a hand operation by a user and the like, the cam follower (25) of the first group lens movement frame (15) engages with (or abuts on) the cam surface (G1) on the image plane side, and an angle of the cam surface (G1) is an angle that an occurring force in the rotating direction is so as to be a moving direction from the collapsed position (S1) to the wide angle end position (W1). Therefore, the rotating cylinder (21) does not rotate easily, and when the load is removed, returns to a position before the load is received.
