Cooperative control system for prime mover and continuously variable transmission of vehicle

A cooperative control system for a prime mover and a continuously variable transmission of a vehicle, in which the continuously variable transmission is connected to an output side of the prime mover for generating a driving force for running, and in which a clamping pressure to set a torque capacity of the continuously variable transmission is raised and an input torque to the continuously variable transmission is lowered on the basis of a decision of the slip in the continuously variable transmission. A clamping pressure / input torque sequential control raises an actual pressure of the clamping pressure at or after a deciding instant of the slip convergence, and executes a control to complete a restoration of an actual torque of the lowered input torque afterward.

Cover closer

A cover closer having a drive unit for electrically opening and closing a cover of a copying machine or the like is described. The cover closer can ease the burden of manipulation of the cover and minimize the constraints on designing the main body of the copying machine and the like. The cover closer is provided with a compact drive unit having a high reduction ratio by the use of planetary gears which reduce the input torque necessary for opening and closing the cover, so as to downsize an electric motor used in the drive unit. The drive unit can therefore be installed within the hinge structure of the cover closer.

Self-locking deceleration support bearing for photovoltaic support

The invention provides a self-locking deceleration support bearing for a photovoltaic support. The self-locking and deceleration characteristics are realized; the self-locking characteristic is that the large-scale single-shaft automatic tracking photovoltaic support is integrally locked in case of strong wind. The resonance phenomenon with large destructive power is eliminated; the photovoltaic support is protected; due to the deceleration characteristic, the photovoltaic support can be supported and rotated without a long and heavy rotating beam; accurate coaxial installation is not needed;the construction is easy; the foundation settlement photovoltaic support can still operate, the operation reliability is improved, a small speed reducer and a motor can be used for driving the large single-shaft automatic tracking photovoltaic support according to the deceleration characteristic, the manufacturing cost of the photovoltaic support and the power consumption of the motor are reduced,and the bearing has the advantages of being small in size, light in weight and low in manufacturing cost.
