Abstract:
PROBLEM TO BE SOLVED: To provide a rearview lens capable of reducing the lengthwise depth of the whole lens and widening a visual angle.SOLUTION: This rearview lens 1 includes a rearward visibility section 10 and a supplementary rearward visibility section 20. The rearward visibility section 10 has on its back face a reflective layer reflecting a rearward visibility V1 and a peripheral portion. The supplementary rearward visibility section 20 is connected to the left periphery, lower periphery and bottom left periphery of the peripheral portion of the rear visibility section 10, and has a front face and a back face. The supplementary rearward visibility section 20 has reflective layers continuously arranged on the back face, and reflects a supplementary rearward visibility V2 located outside from the edge of the rearward visibility V1 by the reflective layers.
Abstract:
A bench saw including two symmetrical stands (11) joined together, two screw rod mounts (20) mounted on the symmetrical stands (11) at the top, a front table board (30) horizontally fixedly mounted on the screw rod mounts (20) at a front side, a rear table board (40) coupled to two slide plates (41) on the screw rod mounts (20) and horizontally moved relative to the front table board (30) and alternatively set at the horizontal or vertical position, a saw rack (50) mounted on the front table board (30) at the bottom, and a hacksaw (60) movably supported on the saw rack (50) and disposed above the front table board (30) and adjusted by the saw rack (50) to a desired elevation and tilt angle, a plurality of jaw plates (70) respectively mounted on the front and rear table boards (30;40) and having each a plurality of grooves (71) rising one behind another for supporting the workpiece at a desired tilt angle, and a workpiece fixture (80) mounted on the front side of the front table board (30) to hold down the workpiece.
Abstract:
A convertible article includes: a torso bag (1) having a hood (2) detachably securable with the torso bag (1), with an inflatable pillow (23) attached to the hood (2) and inflated for cushioning a wearer's head; a leg bag (3) detachably securable with the torso bag (1) for forming a sleeping bag to be worn by the wearer for sleeping purpose; and a built-in carrying bag (4) inherently formed in the leg bag (3), whereby upon inversion of the built-in carrying bag (4) outwardly from the leg bag (3) and folding and insertion of the remaining portion of the leg bag (3) into the carrying bag (4), the carrying bag (4) can be conveniently carried for storing the torso bag (1), the hood (2) and other items into the carrying bag (4).
Abstract:
The invention discloses a global optimization, search and machine learning method based on the Lamarckian principle of inheritance of acquired characteristics, comprising step 1: constructing an objective function f ( P ) according to the problem being solved, where P represents a set of candidate solutions to the problem; step 2: encoding P into a genetic algorithm (GA) chromosome, inputting or automatically calculating algorithmic parameters of the GA, and initializing the algorithm and the population of candidate solution generation G 0 ={ P 0 1 , P 0 2 , ..., P 0 S }, where S is the size of the population G and 0 stands for the initial generation; step 3:at generation k, optimizing the prevailing population of the candidate solutions G k ={ P k 1 , P k 2 , ..., P k S } iteratively using a Lamarckian "Heredity Operator" and a "Use-and-Disuse Operator" based on the values of f ( G k ); and step 4: outputting the final set of optimal solutions to the problem.
Abstract:
An internally electric heating barbecue is provided. The barbecue includes a cabinet (100) with at least one upper opening. The cabinet (100) has heating units (150) at its both inner sides. The opening has a rack supporting part (140) to support a barbecue rack (200). The opening is 30mm-200mm wide. The barbecue rack (200) consists of a barbecue frame (210) and a support rod holder (220). The barbecue frame (210) is set within the opening, and the support rod holder (220) is set on the supporting part (140). The barbecue rack (200) is equipped with food skewers (300). Each food skewer (300) comprises a handle (310), a support locating part (320) and a food fixing part (330).
