摘要： A rocker arm mechanism opens and closes an intake valve. The intake valve is driven by cam of a cam shaft. The rocker arm mechanism is provided in each of bank. The rocker arm mechanism has a structure which changes a phase of the intake valve while displacing a portion driven by the cam to a circumferential direction of the cam shaft. A structure provided with an inversion mechanism inverts a rotating direction of the camshaft of one bank with respect to a rotating direction of the camshaft of the other bank. A variable valve unit having the simple and same structure can be used in both banks. A phase is varied so that a valve closing timing is set larger than a valve opening timing for each bank.

摘要： An internal combustion engine comprises, an intake valve, an exhaust valve, an exhaust gas purifying catalyst, and a valve mechanism which closes the intake valve after a piston reaches the bottom dead center and opens the exhaust valve before the piston reaches the bottom dead center in a hot state of the internal combustion engine, advances the opening timing of the intake valve from the opening timing of the intake valve in the hot state and retards the closing timing of the intake valve from the closing timing of the intake valve in the hot state when the internal combustion engine is cold, and opens the exhaust valve in substantially the same timing as the opening timing of the exhaust valve in the hot state, and closes the exhaust valve at substantially the same timing as closing timing of the exhaust valve in the hot state when the internal combustion engine is cold.

摘要： A motor of this invention is provided with a sleeve-type bearing impregnated with oil for supporting a rotor assembly including a shaft and a rotor member. A lower face of the rotor is provided with at least two peripheral wall portions, an inner peripheral wall portion and an outer peripheral wall portion, which surround the shaft with a gap therebetween in a radial direction. The peripheral wall portions are accommodated in an annular recessed portion so as to surround an open space over a sleeve constituted the sleeve-type bearing and has a lower top of the most inner part. The lower end of the inner peripheral wall portion is located lower than the lower end of the outer peripheral wall portion, and the lower end of the outer peripheral wall portion is located lower than the lower top of the annular recessed portion.

摘要： A valve system has a piston mounted in a cylinder in one of first and second rocker arms and is adapted to be forced by a return spring, and an engagement projection formed in the other one of the first and second rocker arms and is adapted to abut the piston to cause both of the first and second rocker arms to move in conjunction with each other. The return spring is disposed eccentrically with respect to the piston in such a direction as to get away from the engagement projection. Therefore, it is possible to ensure a sufficient stiffness of a power transmitting section of the valve system and a sufficient valve lift.

摘要： In a variable timing mechanism, valve lifting characteristics are changed to meet the engine power output characteristics when the timing of valve operation is changed. The variable timing mechanism is provided for the side of at least one of an intake and an exhaust valve so that, when a running condition of an internal combustion engine is changed from a low engine speed to a high engine speed, a duration of valve opening of at least one of the intake and the exhaust valve is changed to increase an overlap period of the intake and the exhaust valve at the beginning of the changes in the running condition of the engine.

摘要： When a raising switch (21) or a lowering switch (23) is operated in an electric blind apparatus, an MPU (34) rotates a geared motor (4) so that a take drum (37) winds up or unwinds a lifting tape (10) to raise/lower vanes (13) of a blind. Upon rotation of the take-up drum, a photointerrupter (38) generates pulse signals and the MPU counts the pulse signals to judge a vertical position of the blind. When an opening or closing switch (24, 26) is operated, the MPU rotates the geared motor so that a ladder drum (39) is followingly rotated to wind up one of ladder cords (11) fixed to the ladder drum, thereby to adjust an open/close angle of the vanes. Following rotation of the ladder drum, a photointerrrupter (41) supplies pulse signals to the MPU, which in turn counts the pulse signals to judge the open/close angle of the vanes.
