Abstract: A heat sink and an electronic device are provided. The electronic device includes a circuit board and a heat sink. The circuit board has a heat source, and the heat sink contacts the heat source to dissipate the heat. The heat sink includes a heat dissipating plate and a cover plate. The heat dissipating plate has an inlet region, an outlet region and a vaporization region between the inlet region and the outlet region. The vaporization region is disposed corresponding to the heat source. The cover plate covers on the heat dissipating plate, and a space between the cover plate and the heat dissipating plate forms a channel with an inlet and an outlet. A cooling liquid flows into the channel from the inlet, is vaporized to a gas while passing through the vaporization region, and the vaporized gas dissipates outside the channel through the outlet.

Abstract: A method for flattening a three-dimensional shoe upper template is provided. The method includes providing a three-dimensional last model, obtaining a three-dimensional grid model, obtaining a three-dimensional thickened grid model, obtaining a two-dimensional initial-value grid model, and obtaining a two-dimensional grid model with the smallest energy value. A system and a non-transitory computer-readable medium for performing the method are also provided. The method makes it possible to precisely flatten a three-dimensional last model with a non-developable surface and thereby convert the three-dimensional last model into a two-dimensional grid model.

Abstract: A method for executing heating according to property of food is provided, in which a cooking appliance is provided with a reading device, a displaying screen, and a printing device. The cooking appliance forms a heating zone, which receives sensors and an ultrasonic scanner arranged therein. An object-to-be-heated is placed in the heating zone and the ultrasonic scanner scans and displays an outside configuration of the object on the displaying screen to allow a user to apply an automatic process or manual selection of a temperature difference between a single point or an average of multiple points for more than one or two points and another point for carrying out a heating operation. The sensors detect a temperature difference between a surface temperature and an interior temperature of the object in order to ensure that the temperature difference is kept constant.

Abstract: A method of heating food is provided, which employs a cooker provided with a control program and a reader to identify a food package attached with a coded object which embodies the parameters associated with the food package, the parameters including temperature and time, whereby the contents of the parameters of the coded object can be read by the reader and compared by the control program so that the control program can issue commands to conduct a heating procedure according to the contents of the parameters of the coded object. Thus, the food package can be heated or cooked more easily, conveniently, safely, and economically, and the disadvantages resulted from incorrectly manual operations can be avoided.

Abstract: A bandgap voltage reference circuit includes an operational amplifier, a first transistor, a second transistor, a third transistor, a first resistor, a second resistor, a first diode, a second diode, and a divider. The first transistor, the second transistor, and the third transistor form current mirrors. The reference current of the current mirrors is generated according to the first diode, the second diode, and the first resistor. The reference voltage of the voltage reference circuit is output from the first end of the second resistor. The divider is coupled to the second end of the second resistor so that the reference voltage of the voltage reference circuit can be reduced.

Abstract: A composite for inhibiting algae growth comprising a polypore base carrier and a nano-metal mixture coated on the carrier, wherein the mixture comprising a nano-metal particle and a substance for fixing the particle on the carrier.

Abstract: An anti-slipping board is disclosed. The board has a flat plate which is provided with a plurality of protruded rounded floating bodies having a rounded protrusion at the center of each floating bodies, characterized in that the connection region of the protrusion and the floating body, and the connection region of the floating body with the flat plate are arch-shaped structure with different arch angle to prevent debris from collection.

Abstract: An anti-slip floor unit includes a board formed thereon with a plurality of spherical swells, each of the spherical swells having a protuberance a center thereof, the spherical swells being equidistantly arranged on a top of the board, whereby the dirt can be prevented from accumulating in blind spots thereby making it easier to clean the anti-slip floor unit and prolonging its service life.

Abstract: A conducting assembly of a micro switch includes an insulating member which is made up of two molded pieces and a conducting unit which is enclosed partially by the molded pieces. The conducting unit includes a leg portion which is provided with a longitudinal reinforcing member that is formed along its length. The reinforcing member is partially enclosed by the insulating member.

Abstract: A common conducting unit for a contact switch includes a mounting plate that has an elongated flat portion with two parallel end edges, and first and second end plate portions extend integrally and perpendicularly from a respective one of the end edges in the same direction. The first end plate portion has an engaging groove formed therein and extends parallel to the end edges of the flat portion. A spring mounting portion extends integrally and perpendicularly from an end edge of the second end plate portion. A through-opening extends from a position adjacent to the end edge of the first end plate portion to a position adjacent to the end edge of the second end plate portion.

Abstract: A paperboard cutting machine which includes a main unit, two locating tables separately at two sides of the main unit, and a movable template having cutter bearings fixed thereon. The movable template is allowed to reciprocally move over the two locating tables and therefore allows paperboard put on the cutter bearings to be pressed and but into desired pattern by two cylindrical rollers in the main unit. Different sizes of paperboards may be cut on such paperboard cutting machine in mass production while the machine can be operated much safer even by inexperienced workers.
