A filter device includes a main body with a tubular shape having at least two outflow openings formed in a sidewall thereof with an interval in between around a tube axis for passing fluid such as oil; and a filter member with a tube shape embedded in the main body around the tube axis thereof to pass column portions formed between the outflow openings for closing the outflow openings. At least one of the column portions has a groove formed in an inner surface thereof to extend along the tube axis of the main body.

A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).

In a continuously variable transmission of the type in which a speed change ratio is changed in a manner that the radius of rotation of a belt wound around a drive pulley and a driven pulley is varied by changing the width of a groove between the pulley parts of each pulley with an oil pressure. A control means for controlling an oil pressure in various control modes shifts the control mode from a hold mode to a start mode, when a driver manipulates a vehicle carrying the continuously variable transmission with his intention to start the vehicle, and an amount of discharge flow of an oil pump for generating an oil pressure exceeds a preset value. The safety factor in a stationary state is calculated using the effective tension of the CVT belt, secondary side oil pressure, and the speed change ratio. Using the calculated stationary state safety factor, a manipulated variable previously gained, and a changing rate of the primary oil pressure, a safety factor in a speed change state (transient state) is calculated. A manipulated variable of the speed change control means is limited so that the safety factor in a speed changing state exceeds a predetermined value. When the speed change performance may be damaged with the limitation of manipulated variable, a necessary quantity of the line pressure or the CVT input torque is corrected so as to increase the limit value.

A control device for an electric injection molding machine designed to advance and retract a screw in a heating cylinder by an injection motor includes a screw position detector for detecting a screw position to output a screw position detection signal, a speed pattern generator for generating a speed setting pattern signal which indicates relationship between time and screw speed. An integration unit integrates the speed setting pattern signal to obtain a moving stroke of the screw. And a generation unit generates a position instruction signal on the basis of the moving stroke and a screw position when injection is initiated. To generate a speed instruction signal, the screw position detection signal is subtracted from the position instruction signal as a manipulated variable of feedback and the speed setting pattern signal is applied to the position instruction signal as a manipulated variable of feed forward. Thus, accuracy at the speed changing positions can be improved, thus improving operability.
