    摘要： A valve operating system of an internal combustion engine enabling both valve working angle and phase to be varied, includes a variable working angle control mechanism being responsive to a supply pressure of working fluid to adjust a working angle of an intake valve, and a variable phase control mechanism being responsive to a supply pressure of working fluid to adjust a phase of the working angle of the intake valve. A control unit controls the supply pressure to each of the control mechanisms depending on engine operating conditions. In a cold-engine state that the temperature of working fluid is below a predetermined temperature, an intake valve open timing is retarded in comparison with a predetermined stability-limit valve open timing, by limiting a controlled variable of at least one of the control mechanisms.

    摘要： In a magnetic recording and reproducing apparatus according to the related art, since positions of central points of radiuses of curvature of opposing arc portions of a guide groove are coincident with each other in the direction in which a movable chassis is moved, it is difficult to make the whole of the magnetic recording and reproducing apparatus become light in weight and small in size. A magnetic recording and reproducing apparatus includes a fixed chassis (24) to which a rotary head drum (25) is attached, a movable chassis (23) slidably supported to the fixed chassis (24), a cam gear (51) rotatably supported to the fixed chassis (24) or the movable chassis (23) and which has a cam pin (51a) and a cam plate (59) attached to the movable chassis (23) or the fixed chassis (24) and which has a guide groove (65) with which the cam pin (51a) is slidably engaged, wherein the cam pin (51a) is moved along the guide groove (65) as the cam gear (51) is rotated, whereby rotation operation of the cam pin (51a) is transformed into slide operation of the movable chassis (23) to make the movable chassis (23) come close to or come away the rotary head drum (25). The guide groove (65) includes an arc-like eject side slide portion (66) which is dented in the opposite side of the rotary head drum (25), an arc-like play side slide portion (67) which is dented in the side of the rotary head drum (25) and a slide portion (68) continued to one side of the eject side slide portion (66) and the play side slide portion (67) and which is extended in the direction substantially perpendicular to the direction in which the movable chassis (23) is moved, positions of central points of radiuses of curvature of the eject side slide portion (66) and the play side slide portion (67) being displaced in the direction perpendicular to the direction in which the movable chassis (23) is moved.

    摘要： An intake valve control apparatus for an internal combustion engine includes a first variable valve operating mechanism capable of varying an operation angle of an intake valve continuously, a second variable valve operating mechanism capable of varying a maximum lift phase of the intake valve continuously, and a controller that controls an intake air amount mainly by varying the operation angle and the maximum lift phase of the intake valve. The controller is configured to, when one of the first and second variable valve operating mechanisms is at a phase position different from a predetermined start stage phase position at engine start, correct a phase position of the other of the first and second variable valve operating mechanisms in accordance with a present phase position of the one of the first and second variable valve operating mechanisms. An intake valve control method is also provided.

    摘要： In a compression ratio controlling apparatus and method for a spark-ignited internal combustion engine, the variable compression ratio mechanism is controlled by a compression controlling section on the basis of a detected engine speed and engine load in such a manner that the compression ratio is varied toward a target high compression ratio when the engine load falls in a predetermined low load region and toward a target low compression ratio when the engine load falls in a predetermined high load region and a predetermined delay is provided in a variation in the compression ratio toward one of the target high and low compression ratios in accordance with at least one of an engine driving history immediately before a transient state of a change in the engine load occurs and a wall temperature of a combustion chamber of the engine immediately before the transient state thereof occurs.
