A system for controlling the hydraulic pressure of a hydraulic control circuit of an automatic, variable speed transmission during a shift operation is provided. The hydraulic control circuit includes a plurality of hydraulic pressure control valves, a plurality of flow path switching means and a plurality of solenoid valves for controlling the engagement and disengagement of clutches and brakes in the transmission. The energization of the solenoid valves disposed in the hydraulic control circuit is controlled by an electronic system, which comprises a large scale integrated semiconductor logic unit, a semiconductor read-only memory, a semiconductor read-write memory and as required, input/output ports. The semiconductor read-only memory stores, inter alia, hydraulic pressure control program data which become operative during a selected one of the shift modes, each of which comprises a combination of the current speed stage and the speed stage to be established, and which controls the hydraulic pressure of the hydraulic control circuit by a repeated deenergization and energization of the solenoid valve for a given time interval during the shift operation.A signal indicative of a shift lever position is applied to the electronic system from a shift lever detecting means. Also a signal indicative of the current vehicle speed is applied thereto from a vehicle speed signal generating means. Finally, a signal indicative of a throttle opening is applied to the system from a throttle opening detecting means. In response to these signals and based on the constants data and the program data which are stored in the read-only memory, the electronic system determines a speed stage to be established. The hydraulic pressure in the hydraulic control circuit is controlled, simultaneously with a switching of the speed stage, on the basis of the hydraulic pressure controlling program data, thus reducing any rapid fluctuation of the vehicle speed or impulses during a shift operation.

A vibration damping device in which vibration damping performance of a damper having a chamber holding a rolling member is improved. The vibration damping device is adapted to damp vibrations resulting from a pulsation of torque applied to a rotary member by an oscillating motion of a rolling member connected with the rotary member while being allowed to rotate relatively therewith. The vibration damping device is provided with a casing member enclosing the rolling member, and a sealing member that connects the casing member with the rotary member in a manner such that the rotary member is allowed to rotate relatively with the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held to oscillate.

A vibration damping device which can improve a vibration damping performance of a damper having a chamber holding a rolling member. The vibration damping device is applied to a power transmission unit having an input side rotary member that transmits a power to an elastic member and an output rotary member that is rotated by the power transmitted from the elastic member. In order to damp vibrations of the output rotary member, the vibration damping device is comprised of a holding chamber rotated integrally with the input side rotary member and a rolling member held in the holding chamber in a manner to rotate in a same direction as the output side rotary member while being allowed to rotate relatively therewith.

A clevis pin (connecting pin) (26) is inserted into a clearance hole (72), and is displaceable relative to an operating pedal (16). A pivotal moving link (68) is disposed between the clevis pin (26) and a sensor pin (64) of a load sensor (30). A reaction force applied from the clevis pin (26) to the load sensor (30) always acts in a substantially constant direction (substantially leftward in FIG. 1A) even if the operating pedal (16) and an operating rod (22) are pivoted relatively around the axis of the clevis pin (26) in accordance with the depressing operation of the operating pedal (16). Thus, the detecting accuracy of the load sensor (30) is heightened, and variation in detecting accuracy is prevented, rendering the high reliability.

A dynamic damper for attenuating torsional vibration of a rotary member, in which a weighted center of a rolling member is offset from a geometric center to trace an elliptical orbit of a cycloid pendulum. The dynamic damper including, a housing having a rolling surface on its inner surface is formed in a rotary member, and a rolling member held in the housing in a manner to be rolled on the rolling surface by torque pulse exerted on the rotary member. In the dynamic damper, a curvature of the rolling surface is entirely constant, and a radius of the rolling member is smaller than that of the rolling surface. A weighted center of the rolling member is offset from a geometric center thereof. The rolling member is guided by a guiding mechanism to roll on the rolling surface.

A dynamic damper for attenuating torsional vibration of a rotary member irrespective of oscillation angle of a pendulum.The dynamic damper 1 comprises a pendulum 3 oscillated by torque pulse of the rotary member 2, and oscillation frequency of the pendulum 3 is tuned to a torque pulse frequency. In a suspending member of the pendulum, a pivot point P and an oscillation length L of the pendulum 3 are changed in accordance with an increase in an oscillation angle of the pendulum 3. Therefore, a mass of the pendulum 3 is allowed to oscillate while tracing an approximate cycloid path so that the torsional vibration of the rotary member 2 can be attenuated irrespective of oscillation angle of the pendulum 3.

Job management information is analyzed to extract post printing process information on a post printing process from the job management information on the basis of the analysis result. A stylesheet corresponding to the extracted post printing process information is selected from a stylesheet storing unit which stores a stylesheet functioning as layout data for laying out and outputting post printing process information in accordance with the output form of an output destination. Work order form data of the corresponding post printing process is generated on the basis of the selected stylesheet and post printing process information.
