Abstract: The present invention discloses a force feedback hand training method including: providing a training game content and adjusting the training game content based on predetermined parameters; displaying the training game content on a display; determining whether an input button position of at least one input signal from a hand training device matches a predetermined input button position; and storing a determination result in a storage module.

Abstract: A semiconductor device includes a substrate, a dielectric layer disposed over the substrate, and an interconnect structure extending through the dielectric layer. The dielectric layer includes a low-k dielectric material which includes silicon carbonitride having a carbon content ranging from about 30 atomic % to about 45 atomic %. The semiconductor device further includes a thermal dissipation feature extending through the dielectric layer and disposed to be spaced apart from the interconnect structure.

Abstract: A valve with a structure limiting of the turning angle of the valve knob includes a valve and knob installed on the valve. The valve contains a raised tube, which contains a globe valve brake axle protruding in the center; and the knob contains a connecting groove which can be affixed to the top of the globe valve brake axle. One side of the raised tube of the valve forms a section of fillister plane along the circumference, and two crosswise ends of the fillister plane form first and second blades vertically. The bottom of the connecting groove of the knob forms an expanded groove, and one side of the fillister plane forms an inner protrusion. The structure of the turning angle of the knob is completed concealed inside the knob.
