Abstract: A footwear includes an outsole and an insole. The outsole includes multiple support portions connected to an annular peripheral portion, and cooperating with a hole-defining surface to define multiple block-receiving holes, and an annular inner ridge extending from the hole-defining surface into the holes. The insole includes multiple wearproof blocks and an insole body formed with an annular outer groove and multiple embedding grooves between adjacent pairs of the wearproof blocks. The insole body is supported by the support portions and the peripheral portion with the inner ridge received in the outer groove, the support portions received in the embedding grooves, and the wearproof blocks received fittingly in the holes.

Abstract: This invention relates to a method for manufacturing a damping shaft sleeve that includes: forging a base material into a billet that includes a cylindrical body having two opposite ends and an annular flange formed on one of the opposite ends; forging a shaft hole in the cylindrical body; inverting the base material and forming two annular grooves that are respectively indented from two opposite surfaces of the annular flange; forging the billet to form the annular flange into a bottom wall and a side wall, the bottom wall cooperating with the side wall to form an asymmetrical and helical groove; and forging the shaft hole to pass through the cylindrical body of the billet.

Abstract: The invention is a surface light source generator that can provide surface light with a high luminosity and uniformity and a small dispersion angle. The invention uses the light emitting diodes (LEDs) for industrial standard light bulb packaging as its basis. By redesigning the shape of the LED elements (e.g., hexagonal pillars, quadrangle pillars or triangular pillars) and disposing a plurality of same type LEDs together, a surface type illuminator comprised of many closely packed LED elements is formed. Using the convergent effect of the convex lens on top of the LED elements, the light dispersion angle is controlled within 15 degrees. Such a technique of packing many LED elements together can increase the unit area luminosity of the surface light source generator and, at the same time, achieve a high luminosity and uniformity.

Abstract: An electric oven including a base formed with a shoulder surrounding circumference of a top thereof, a disk fixedly mounted on the base, an electric heater fixedly mounted the disk, an annular member having a plurality of rollers at a circumference thereof and disposed on a top of the disk, a tray disposed on the annular member and having a tubular portion at a center thereof, a plug fixedly fitted within the tubular portion of the tray, a motor arranged within the base and having an output shaft extending upwardly out of the base and the annular member to engage with the plug, an outer housing fixedly mounted on a top of the base and surrounded by the shoulder of the base, an outer cover snugly fitted on a top of the outer housing and provided with a cylindrical protuberance having two opposite lugs at an upper end thereof and two opposite projections at a lower end thereof, an inner cover fixedly mounted on a bottom side of the outer cover, and a door having a flange at a lower edge thereof which is rotatab

Abstract: An apparatus for dehydrating fruits, vegetables and foods includes a stand having a recess, a blowing chamber having a top formed with a plurality of perforations, a fan chamber under the blowing chamber and communicated with the blowing chamber, and a tubular member close to a vertical inner wall of the recess, an electric motor fixedly mounted within the recess of the stand, a fan fitted within the fan chamber and drivingly connected with the electric motor, a base having a center hole fitted over the blowing chamber and a tubular portion close to an edge of the base, a plurality of trays each having a tubular portion aligned with the tubular portion of the base, a cover adapted to fit on an uppermost one of the trays and provided with a plurality of holes, an axle extending through the tubular member of the stand and the tubular portions of the trays, and a leg frame telescopically mounted on a bottom of the stand, whereby the trays can be easily turned open or closed as desired.

Abstract: A multi-purpose cooker (10) having a base member (12) including a compartment (20) therein, a cover member (14) cooperable with the base member (12) for providing a food-steaming and food-dehydrating chamber (16) including the compartment (20) of the base member (12), a food retaining member (e.g., 42) retainable in the chamber (16) for supporting food to be dehydrated, and a food retaining member (e.g., 48) retainable in the chamber (16) for supporting food to be steamed. Preferably the base member (12) includes a heater (22) and a switch (78) for selectively energizing the heater (22) for heating water (11) retained in the compartment (20) during the steaming operation. Most preferably the base member (12) also includes a fan assembly (58), and the switch (78) is operable to selectively energize a motor (62) of the fan assembly (58) and the heater (22) simultaneously for dehydrating food, and to energize the heater ( 22) without the motor (62) of the fan assembly (58) for steaming food.

Abstract: A dehydrator for vegetables or the like is provided. The dehydrator includes a base having a heating wire and a concealed plug, a plurality of circular containers engageable each with another, and a cover mountable on top of one of the circular containers. The dehydrator can be collapsed by increasing the engagement between the respective circular containers and inverting the cover, when not in use.
