Abstract: A transportation head for a microchip transfer device capable of minimizing mechanical and chemical damage to a microchip, a microchip transfer device having same, and a transfer method thereby, and the transportation head includes a head body having a pickup area and a dummy area; a first protruding pin disposed in the pickup area of the head body; and a liquid droplet attached to the first protruding pin.

Abstract: A magnetic block toy, more specifically, a magnetic block toy which secures mating spots of magnets at the planes of blocks to be combined by extending a travel segment of a magnet to the plane of a block with increased magnetic Gauss level by exposing part of a casing that covers outer surface of the magnet, and provides audible effects during play. For this purpose, the present disclosure incorporates a partially exposed cylindrical magnet with a longitudinal open groove in the casing and a guide pin formed at both right and left sides of the casing. Sound is produced by the inserted guide pin of the casing in a first guide groove and a second guide groove of a plane block or a cube block when it contacts the first guide groove and the second guide groove upon the movement of the magnet.
