A semiconductor package includes a carrier, a chip, a stiffener and an encapsulant. The chip is disposed on the carrier. The stiffener is disposed around the chip, directly contacts the carrier, and is mounted on the carrier. The encapsulant is adapted to seal the chip and the stiffener.

A saw blade protective cover device of a table saw comprises a protecting cover seat and a protective cover which is pivoted with the protecting cover seat, wherein the protecting cover is provided with an elastic positioning part, when the elastic positioning part of the protecting cover is propped to the protecting cover seat, the protecting cover is far away from a saw blade so that the saw blade can be exposed for carrying out operations which are related to workpiece sawing, such as measurement of the height of the saw blade which is higher than a working table surface or the inclination angle of the saw blade to a working table; and when the elastic positioning part of the protecting cover generates elastic deformation under the action of external force and the protecting cover is caused to be staggered with the protecting cover seat, the protecting cover is contacted with the working table surface and covers the saw blade for preventing a user from carelessly touching the saw blade.

The invention discloses an electric cut-open knife for passion fruit. The electric cut-open knife is mainly characterized in that a lower clamping plate is arranged on the upper portion of a bottom plate of a knife rest, two sets of upward needle tips different in height are arranged at the rear end of an upward concave arc surface of the lower clamping plate along the arc surface, and the four corners of the lower clamping plate are connected with the lower ends of four support feet of a support; a first round through hole is formed in the center of a rectangular flat plate on the upper portion of the support; a pull rod is arranged in the first round through hole, and after the lower portion of the pull rod is sleeved with a compression spring, the pull rod is perpendicularly welded together with an upward convex arc top face of an upper clamping plate; an annular shoulder is arranged on the upper portion of the pull rod, and the upper portion of the pull rod and a handle are integrated through injection molding; two sets of downward needle tips different in height are arranged at the rear end of a downward concave arc surface of the upper clamping plate along the arc surface, and the downward concave arc surface of the upper clamping plate is opposite and parallel to the upward concave arc surface of the lower clamping plate; a knife body is composed of a blade, a plug, a wire, a fixing plate, a single-phase alternating current linear motor, a knife holder, a knife handle and a switch. The passion fruit can be cut open simply, conveniently and easily through the electric cut-open knife.

The invention discloses an automatic plate splicing machine having a lateral material ejecting function and belongs to the technical field of wood processing machinery. The automatic plate splicing machine comprises a rack, an upper heating mechanism, a lower heating mechanism, a plate material pressing mechanism, a material turning mechanism and a material pushing mechanism and is characterized in that the material pushing mechanism comprises a pair of material pushing plate acting cylinders, material pushing plates and a pair of material pushing plate synchronizing devices. In a pair of rack left columns, a plate material end ejecting acting cylinder is arranged on one rack left column on the rear side of the left end of the rack and located at the position corresponding to the rear end of a plate material cavity, and the material ejecting acting cylinder column of the plate material end ejecting acting cylinder faces the plate material cavity. It is guaranteed that the plate materials in the plate material cavity are pushed into a plate material inlet port of a plate material moving channel under a balanced acting force one by one, the motion resistances of material pushing plates are decreased, the material pushing plates are protected, and the energy consumption of the pair of material pushing plate acting cylinders is reduced. The irregular ends of the plate materials located at the plate material cavity in an overlapped state can be regular to facilitate sawing executed by a sawing mechanism only to the ends, wood resources are saved, and the quality of whole spliced plate sheets is guaranteed.
