Abstract: A lifting base for a LCD monitor includes a frame, a lifting device and a pair of clamping members. The frame has two rails extending from two sides respectively. The lifting device has a pair of sliding parts and a pair of guiding plates. The sliding parts are connected at the bottom ends with the top ends spreading apart like the shape of an English letter V. Two outer edges of each sliding part are bent to form a guiding rail thereat. The sliding parts are secured with the guiding plates connected to a monitor. The guiding plates are inserted within the rails of the frame. The clamping members are two torque springs in an opposite position. Each clamping member has one end secured to the frame and another end connected with a roller to engage with the rail of each sliding part of the lifting device for locating purpose.

Abstract: A heat-sink for heat-liable electronic devices provides multiples of lateral holes in each vertical fin to separately create a lateral passage in relation with longitudinal troughs to guide air currents flowing in various directions to boost the air conduction thus to improve heat dissipation effects.

Abstract: A heat treatment furnace and conveyor with multi-conveyance, wherein the top of the furnace has a feeder and the bottom of which has a disposal. The inside of the furnace has a number of conveying units, each unit is in circular status lined up and move with the feeder at the top of the first pallet, and the end of each pallet is connected to the beginning of the next pallet, and the end of the last pallet is connected to the disposal. This reduces the width of the furnace and extend the length of conveying which enhances the heat treatment processing time. The furnace is also divided into several sections, as a heating section and a cooling section. The heating section is equipped with electric heating elements while the cooling section is not. The pallet belt is in a flat surface with some ribs to prevent objects from sticking or sliding off.
