摘要:
A system for conditioning an alkaline etching solution for reducing contamination in a silicon wafer etching process. The system includes a conditioning tank for mixing a conditioned alkaline etching solution, the conditioned alkaline etching solution including a conditioning chemical; a conditioning chemical introduction system configured to add the conditioning chemical to the conditioning tank; and a buffer tank for storing the conditioned basic etching solution before using the conditioned alkaline etching solution in an etching process.

A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with shape adjustability for accommodating a rider's particular riding preferences. Shape adjustability may allow the rider to reduce pressure points between the highback and the leg, particularly the calf muscle, for increased comfort while maintaining proper heelside support for board control. Shape adjustability may also allow the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. The highback may employ one or more sections that may be selectively arranged to achieve a desirable highback shape for board response and rider comfort. The highback may be rigidly fixed in the selected shape to maintain comfort while delivering desired power transmission to the board.

A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is provided with stiffness adjustability for accommodating the rider's particular riding preferences. Adjusting the highback stiffness allows the rider to selectively increase or decrease force transmission and board response based on individual riding preferences and/or riding conditions. Adjusting highback stiffness may also allow a rider to reduce pressure points between the highback and the leg, particularly the rider's calf muscle, for increased comfort while maintaining heelside support for board control. The highback includes a back member that may employ one or more sections that can be selectively adjusted to achieve a desired highback stiffness for board response and comfort. The degree of stiffness may be established by adjusting the flexibility of the highback at preselected locations of the back member. One or more interchangeable control elements may be mounted to the back member to adjust the highback stiffness.

An adjustable strap that limits separation of the strap portions from each other. The strap provides for quick and easy one hand operation by allowing a user to fully loosen and tighten the strap without the need for rejoining the strap portions to each other. The strap may also maintain the overlapping sections of the strap portions in close proximity and generally parallel to each other, such as when bending and/or adjusting the strap across a curved surface, to substantially reduce the likelihood of a loose strap end. The adjustable strap may include an engagement strap with a fastening device, such as a ratchet buckle, mounted to one end thereof, and a ratchet strap that passes through the ratchet buckle to be adjusted relative to the engagement strap for a desired tightness. The engagement strap may include a stop that coacts with the ratchet strap to limit relative movement between the engagement and ratchet straps. An elongated slot may be disposed along the engagement strap to guide and limit travel of an anchor to which is fastened the tip of the ratchet strap.
