摘要:
Disclosed is an azo compound represented by the following general formula (1). (In the formula, R 1 and R 2 independently represent a hydroxy group or a polymerizable functional group selected from the group consisting of (meth)acryloyl groups, (meth)acryloyloxy groups, (meth)acrylamide groups, vinyl groups, vinyloxy groups and maleimide groups; X 1 represents a single bond when R 1 is a hydroxy group or represents a linking group expressed as -(A 1 -B 1 ) m - when R 1 is a polymerizable functional group; X 2 represents a single bond when R 2 is a hydroxy group or represents a linking group expressed as -(A 2 -B 2 ) n - when R 2 is a polymerizable functional group; R 3 and R 4 independently represent -OR 7 , a hydroxyalkyl group having 1-4 carbon atoms or -CONR 8 R 9 ; and R 5 and R 6 independently represent a carboxy group, a sulfo group, a nitro group, an amino group or a hydroxy group.)

摘要:
The present invention relates generally to a device of and a method for correcting spinal deformities, such as scoliosis and kyphosis. The invention employs the superelasticity or pseudoelasticity, such as found in a nickel-titanium alloy, to provide a continuous, predictable, and controllable correction force and to achieve a gradual and full correction. The correction force can be exerted on the deformed spine either at the time of the spine surgery or after the surgery or both, to afford a full or substantially full correction. The continuous and controllable correction force of the present invention is safer than an instantaneous and large correction force applied only at the time of surgery. Additionally, the continuous and controllable correction force is capable of gradually and fully correcting the spinal deformities without any post-operative manipulation of the correction device or re-operation.

摘要:
An AC-DC converter that includes a plurality of power conversion units that overlay their signals to generate a DC signal with low voltage level, small voltage and current ripples, but high DC current. The DC signal is further filtered by a LC low pass filter to further minimize the ripples before output to the load. In one embodiment, the plurality of power conversion units is preferably powered by a plurality of input pulse generators. In an alternative embodiment, the power conversion units is powered by a input pulse generator circuit that includes a plurality of n-channel MOSFETs arranged in a full bridge configuration whose gate voltages are controlled by a plurality of pulse generators.
