摘要:
A multistage socket including a main body having a disc section. Multiple fixing blocks are disposed on one face of the disc section at equal angular intervals. A movable block is arranged between each two adjacent fixing blocks. The inner end faces of the movable blocks facing the center of the disc section define a polygonal hole. The movable blocks are resiliently movable toward or away from the center of the disc section. A rotary member is rotatably fitted around the disc section of the main body. Multiple arced guide sections are symmetrically formed on an inner face of the rotary member corresponding to the movable blocks. Each arced guide section has multiple recessed arced faces with different thickness. When rotating the rotary member, the outer ends of the movable blocks can abut against the opposite recessed arced faces of the arced guide sections with the same thickness. Therefore, the movable blocks can be located in different recessed arced faces to vary the distance between the movable blocks and the center of the disc section so as to adjust the size of the polygonal hole in accordance with the sizes of different nuts or bolts.
摘要:
A catheter having a balloon comprised of a polymer material comprising first monomer units of an alkyl amide having 2 to 6 carbon atoms and second monomer units of an alkyl amide having 7 to 12 carbon atoms. The first and second monomer units are copolymerized with each other in a random fashion to form a random copolyamide polymer.
摘要:
The present invention relates to substituted imidazopyrazines of the general Formula I which modulate the activity of protein kinases (“PKs”). The compounds of this invention are therefore useful in treating disorders related to abnormal PK activity. Pharmaceutical compositions comprising these compounds, methods of treating diseases utilizing pharmaceutical compositions comprising these compounds and methods of preparing them are also disclosed.
摘要:
A light-catalyst equipped electric fan includes an adjustable holding part, a light tube secured to the holding part for producing ultraviolet light, a first motor disposed behind the holding part, a fan blade connected with the first motor, a second motor, a filtering honeycomb having titanium dioxide applied over it, and two joined protecting nets arranged at a front of the electric fan, and connected with an output shaft of the second motor; the filtering honeycomb is disposed between the protecting nets, and stuck on a rear side of a front one of the nets; thus, when the motors and the light tube are activated, air will pass through the filtering honeycomb, and ultraviolet light will shine on the titanium dioxide, and in turns, air passing through the filtering honeycomb is purified, and germs in the air killed.

Polishing pads with multi-modal distributions of pore diameters are described. Methods of fabricating polishing pads with multi-modal distributions of pore diameters are also described.
摘要:
Polishing pads with a polishing surface layer having an aperture or opening above a transparent foundation layer are described. In an example, a polishing pad for polishing a substrate includes a foundation layer having a global top surface and a transparent region. A polishing surface layer is attached to the global top surface of the foundation layer. The polishing surface layer has a polishing surface and a back surface. An aperture is disposed in the polishing pad from the back surface through to the polishing surface of the polishing surface layer, and aligned with the transparent region of the foundation layer. The foundation layer provides an impermeable seal for the aperture at the back surface of the polishing surface layer. Methods of fabricating such polishing pads are also described.
