Abstract: A device for cutting a hamburger into a variety of equal size pieces that is both light-weight, portable and easy to clean for use at home or away. The device is an article of manufacture that can be made by existing manufacturing methods using commonly used raw materials, including recycled materials. The device includes extensions connected to a handle by a column and is designed to fit on top of a hamburger with each extension containing a slot to guide the cutting of the hamburger. Notches are included to guide the placement of toothpicks that are inserted into the hamburger before cutting and are used to hold the individual cut pieces together after removing the device. The device addresses the needs of those consumers that may have difficulty eating a full-size hamburger and would benefit from eating smaller pieces, such as the elderly and children.

Abstract: A chopping aid device for use in chopping of firewood includes a frame to pre-vent pieces of wood from spreading into the surroundings outside the chopping aid device during chopping. In order to make chopping of wood easy, fast and safe, the chopping aid device has a support with flexible spikes to keep the firewood in an upright position within the frame.

Abstract: The invention relates to a tool holder with a tool holding fixture, in particular a clamping chuck such as a contracting chuck, a draw-in collect chuck, a hydraulic expanding chuck and a high-precision chuck, and a shank of a tool, in particular a rotary tool, accommodated in it, wherein the tool holder contains a means for preventing the tool from being pulled out, locking it against axial displacement. This pull-out preventing unit comprises at least one locking element and at least one locking groove, which corresponds to the said locking element, receives it and interacts with it in a positively locking manner. In this case, both the locking element and the locking groove are formed at least partly in the manner of a ball head. Preferably, the tool has the locking grooves.

Abstract: A lift pin is provided for manipulating a substrate above a support surface of a substrate support and uniformly transferring heat from the substrate support to the substrate. The lift pin includes a pin shaft. The pin shaft includes a cross-section having at least three equal edges and round corners configured alternatively. A pin head is an end portion of the pin shaft, wherein the pin head has a convex support surface larger than the cross-section of the pin shaft. A flat portion is disposed on a central area of the convex support surface for directly contacting the substrate.

Abstract: Provided are device for assembling groups of eyebrow beautifying needles and method therefor. The assembling device comprises a base, a sliding block including two resilient members biased between the base and the sliding block, a central fastener for fastening the sliding block on or above the base, a holding assembly comprising a plurality of clamping posts vertically disposed on the base, and a plurality of holes with the sliding blocks passed through. Groups of eyebrow beautifying needles are adapted to insert into holding heads of the clamping posts with needle tips being flush in the holding heads of the clamping posts, and the needles in each group are fastened together by soldering. Moreover, sleeves of different colors or marks may be put on the needle groups for facilitating identifying the number of needles in each group.

Abstract: A printed-board supporting apparatus includes a support pin that is attached to a pin-supporting table. An image of the support surface of the support pin is taken by a mark-image taking device, at a first position where a center of an image-take surface of the mark-image taking device is expected to coincide with a center of the support surface of the support pin. Another image of the support surface is taken at a second position where the center of the image-take surface is distant from the center of the support surface by a predetermined distance. At the second position, the image of the support surface is formed on the image-take surface at a position corresponding to the height of the support surface. Based on the position corresponding to the height of the support surface, the height of the support surface relative to the mark-image taking device is obtained.

Abstract: An alignment weight is provided. The alignment weight includes a body of material having first and second opposing surfaces. A number of depressions are formed in the first surface. The depressions receive pins of a floating pin field when placed on a floating pin field during connection of the floating pin field to a printed circuit board.
