摘要:
A honeycomb heat dissipating apparatus made of a composite metal material includes honeycomb cells that are integrally formed by vacuum die casting, and continuous convex and concave distal surfaces disposed around the periphery of the heat dissipating apparatus, and an adjacent surface of each cell is a thin surface, and the heat dissipating apparatus can be in a standalone mode, or combined with other heat dissipating apparatuses. One or more honeycomb heat dissipating apparatuses can be installed on a circuit board or an electronic component of a lamp or an electric appliance, such that the heat dissipating apparatus can dissipate heat quickly by the honeycomb cells without occupying much space. The invention can increase the heat dissipating area for a faster heat dissipating effect and change the stylish appearance to achieve the aesthetic effect.

This invention provides a geometrical structure configuration of maglev forces in a maglev rotational bearing apparatus. The bearing apparatus uses the magnetic forces as the suspension support for the rotational shaft, and utilizes a radial maglev support module to provide two maglev constraint forces perpendicular to and crossing on the axis of rotating shaft and an axial maglev support module to provide three maglev constraint forces parallel to the axis but non-coplanar. From the viewpoint of kinematical geometry, this machine has five linearly independent constraint forces so that the main axis is allowed to be suspended without contact and friction with static elements, and the suspension force in axial direction is better than currently available maglev bearings. The rotational shaft can be driven by a motor to perform high-speed rotational motion with noises free and vibrations free. This technique can be applied to high-speed rotational machines such as turbo molecular vacuum pumps, the spindle of high-speed machine tools, inertial gyroscopes, etc.

The present invention discloses a bag packing mechanism for mushroom cultivation, which comprises two clamping seats, transport means, air duct, pumping means and push rod. Transport means supply collar. Air duct descends through the collar and extends into a bag from the opening of the bag, the two clamping seats clamp the top portion of the bag to close to the outer periphery of the air duct, the pumping means sucks the top portion, the two clamping seats open, the push rod is lowered to push down the collar to put on the top portion, the pumping means blow to open the top portion, the push rod is further lowered to fold the top portion down, the air duct and putter rise, and then complete the automation of packaging job.

A multiple-type pump has a simple construction and superior durability. The multiple-type pump has the capacity to perform air evacuation at high velocities in the atomospheric pressure zone to high vacuum zone range. The multiple-type pump includes: a screw type pump air transfer portion arranged at a downstream portion of the outer surface of a rotor and has a plurality of screw threads and screw grooves with a width of 5 mm or more; a turbo-molecular type pump air transfer portion arranged at an upstream portion and has a plurality of vanes and air transfer grooves; vanes having vane widths of 3 mm or less at the upstream edge, and formed so that the downstream edge is continuous with the upstream edge of the screw threads; a downstream edge of the base of the air transfer grooves formed so as to be continuous with the upstream edge of the base of the screw grooves. The turbo-molecular type pump air transfer portion takes the air brought in from the upstream edge at the time of rotation, compresses it and transfers it to the upstream edge of the screw type pump air transfer portion.
