Abstract:
A space-saving back-up power supply apparatus has length and width dimensions substantially the same as those of a conventional integrated circuit connector. The apparatus includes sockets arranged on its top for making connection to a socket-pluggable integrated circuit such as a standard CMOS RAM, and the apparatus has pins extending from its bottom for making connection to a printed circuit board or connector of a host electronic system. Control circuitry and one or more batteries are located within the apparatus. The back-up power supply is operative to provide power to the socket-pluggable integrated circuit even if the normal power supply of the host electronic system is short-circuited. The control circuitry of the back-up power supply controls the chip enable signal and performs a battery test upon power-up.
Abstract:
A redundancy circuit that consumes no power before or after activation switches a pair of output nodes from a first set of complementary logic levels to an inverted set when it is activated by blowing a pair of fuses.
Abstract:
A molding method of blow-molding a hollow tank body with a built-in component is provided. The method molds the hollow tank body by molding the sheet parisons in the half molds. After the moving cooperation of the half molds, an expanding mechanism of a pre-molding template device, the template half plates and the bases, the half molds are respectively leaned against the closed template half plates, and the sheet parisons are leaned against the half molds by blowing and/or sucking so as to be pre-molded. The tank body is molded after placing the component into it. A pre-molding template device is also provided. An expanding mechanism and the template half plates are mounted on the bases, and the bases are mounted on a rail bracket, the bases are driven by a power device to move on the rail bracket.
Abstract:
A method for molding a two-piece blow molded hollow tank by using auxiliary male molds includes the following steps: 1) blanking two parisons; 2) closing mold halves of a mold and a pre-molding template; 3) pre-stretching the molten parisons by using auxiliary male molds in the pre-molding template; 4) performing internal high-pressure blow molding, and pre-molding two housing portions; 5) opening the mold, and withdrawing the pre-molding template; 6) moving in a component built-in mechanism to perform built-in component connection; 7) moving out the component built-in mechanism; 8) closing the mold for the second time and finally blow molding a hollow tank; and 9) opening the mold and taking out the product.
Abstract:
A computerized method determines similarities between a first image and a second image. The first image is converted into a first grayscale image, and the second image is converted into a second grayscale image, where a number of pixels of the second image is not less than a number of pixels of the first image. Each pixel of the first grayscale image is matched with a pixel of the second grayscale image to create a pixel pair sequence. A similarity value indicating the similarities between the first image and the second image is calculated according to the grayscale value of each pixel in the pixel pair sequence S.
Abstract:
The present invention relates to a polymerizable water-soluble or alcohol-soluble ultraviolet absorber, which is represented by the following formula (I): wherein R1 is H or C1˜5 alkyl; R2 is H, Cl, Br or I; R3 is H or methyl; and m each is an integer in the range from 3 to 12. The above-mentioned compounds are suitable for copolymerizing with one or more monomers to form copolymers so that the UV-light resistance of the copolymer can be efficiently promoted. For example, the polymer made by copolymerizing the above-mentioned compound with acrylate monomers can be applied to the production of optical medical materials, especially contact lenses or intraocular lenses.
Abstract:
An X-ray imaging stand that supports an upright X-ray imaging panel by a column standing vertically through a carriage, includes a bar-like member having a longitudinal bar section that extends from the carriage in the upward direction over the upper end of the X-ray imaging panel and a horizontal bar section that extends from the leading end of the longitudinal bar section in the horizontal direction over the surface of the X-ray imaging panel receiving the X-ray, and a support mechanism that supports the longitudinal bar section of the bar-like member above the carriage such that the angle thereof is variable in plural stages in a plane parallel to the surface of the X-ray imaging panel receiving the X-ray.
Abstract:
A semiconductor device made on a polymer substrate using graphic arts printing technology uses a printable organic semiconductor. An electrode is situated on the substrate, and a dielectric layer is situated over the electrode. Another electrode(s) is situated on the dielectric layer. The exposed surfaces of the dielectric and the top electrode are treated with a reactive silane to alter the surface of the electrode and the dielectric sufficiently to allow an overlying organic semiconductor layer to have good adhesion to both the electrode and the dielectric. In various embodiments, the electrodes may be printed, and the dielectric layer may also be printed.
Abstract:
A dual storage cell memory includes an array of dual storage cells, each of the dual storage cells containing a first memory cell and a second memory cell. The first and second memory cells are well known six-transistor static memory cells with the addition of transfer circuitry for transferring data directly from the internal data nodes of each of the memory cells to its corresponding complementary memory cell without requiring the use of the enable transistors or the bit lines associated with each of the dual storage cells.
