A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.

A manufacturing process of a construction strip includes the steps of (a) evenly mixing a predetermined amount of paint, talcum powder and volatile agent to form a plaster form coating mixture; (b) gradually passing an elongated strip body through an extrusion passage of an extrusion mold, wherein a uniform surrounding clearance between an interior wall of said extrusion passage and said strip body; (c) continuously injecting said coating mixture into said extrusion passage of said extrusion mold in order to fill said surrounding clearance, so that a uniform protective coating is evenly coated on said longitudinal surfaces of said strip body while said strip body is extruded from said extrusion mold; and (d) drying said protective coating to form a hard and durable protective coating shell integrally wrapped around said strip body.

This invention involves a series of articles, dispersions, compositions, methods, and kits. Several aspects of the invention involve dispersed particles made from polymers having a delocalized π-orbital backbone structure, as well as methods for making and using such particles. The delocalized π-orbital backbone allows the polymer to have a high degree of luminosity, useful in many embodiments of the invention. The polymers of this invention can also have bulky substituents to prevent intermolecular π-π interactions that can decrease luminosity. The polymer may also have charged side chains immobilized relative to the backbone, which can allow the polymer to be made into stably suspended micro- or nanoparticles dispersed in solution, sometimes with very narrow size distributions. In some embodiments, depending on the conditions used to synthesize and prepare the particles, the particles each consist of a single polymer molecule. Side groups, including biological, biochemical, or chemical molecules, can be attached to the polymer to provide additional functions, such as altering the luminosity of the polymer, or allowing the polymer to bind to certain molecules, such as in a chemical sensor or in a biological assay.

The present invention is to provide a plasma processing apparatus, whose structure can be simplified, and further, which is capable of forming highly effective plasma and obtaining a satisfactory vertical etching property without involving a problem concerning interference. In the plasma processing apparatus according to the invention, a ground electrode provided at a position opposite to a substrate mounting electrode is configured to be a counter electrode, whose potential is in a floating state, and radio frequency power is branched at an arbitrary position of the radio frequency antenna coil, which generates inductive discharge, into the counter electrode through a capacitor so as to share a part of the radio frequency power used for inductive discharge, thereby generating a self-bias in the counter electrode. In the system, there is provided a mechanism for controlling the radio frequency voltage to be applied to the floating electrode uniformly.

A microelectronic device tester has a mounting member (for mounting a device), a drive shaft connected to the mounting member, and a vibration shaft mechanically in communication with the drive shaft. The drive shaft and vibration shaft are non-coaxial, and the drive shaft has a drive shaft proximal end and a drive shaft distal end. The drive shaft proximal end is connected to the mounting member, and the drive shaft distal end terminates proximal of the entire vibration shaft.

The present invention provides a colorful coating material which consists essentially of a 10 to 40% of paint in weight, a 50 to 90% of talcum powder in weight and a 5 to 10% of volatile agent in weight. The paint, the talcum powder and the volatile agent are evenly mixed to form a plaster form coating mixture. The coating mixture is adapted for coating around an object by means of an extrusion mold to form a protective coating. When the protective coating is dried and solidified, a hard and durable protective coating shell is formed and wrapped around the object.
