摘要:
A system for controlling damping force characteristics for respective shock absorbers, each shock absorber being interposed between a sprung mass and an unsprung mass, in which a control signal to control the damping force characteristic at either or both stroke sides of each shock absorber is derived by a control unit on the basis of a signal indicating a sprung mass behavior, a signal indicating a steering angular displacement of a vehicle steering system, and a signal indicating a steering angular velocity of the steering system. In addition, a control equation to determine the control signal value has various coefficients which are zeroed depending on whether a predetermined steering condition is established.

A control system for a damping force coefficient of a shock absorber for a vehicle suspension provides a controller for correcting the position of a step motor. The controller sets the step motor at a predetermined position in a manner to intermittently move the step motor to a stop position restricted by a stopper and to reversely rotate it by a predetermined number of steps. Therefore, the step motor is precisely set at a home position without using a position detector.

A place-on type assemblable structure includes a foundation beam and an assembly body assembled on the foundation beam. The foundation beam is placed on the surface of the ground via a pluarlity of jack means provided for the fondation beam. The level of the foundation beam can be easily adjusted by extending and contracting the jack means.
摘要:
A process for producing solar collectors of aluminum or aluminum alloys having a selective absorptive coating. Aluminum or its alloy is dipped in a hot aqueous solution containing a silicate. Aluminum alloys can be also used which contain alloying elements such as iron, copper, titanium, nickel, silver and gold.
