Abstract: A stacking structure for breeding chests includes a plurality of mounting members, a plurality of holding members and a plurality of first bracing rods. The mounting members are detachably coupled on the upper edge of a lower layer breeding chest. Each of the first bracing members is detachably bridged one mounting member and one holding member to support the bottom of a upper layer breeding chest. The holding members are bridged by a plurality of second bracing members in a detachable manner to increase the supporting capability for the upper layer breeding chest. By bridging the mounting members and the holding members, the first bracing rods form an access space therebetween to enable breeders to do feeding, clearing or repairing tasks without removing the upper layer breeding chest.

Abstract: An electronic device capable of displaying printed information of optical storage media includes a host and an optical access device. The optical access device has a upper cap which has a display zone. The host has a confirmation window corresponding to the display zone such that users can directly see and read the printed information of an optical storage medium held in the optical access device through the confirmation window and the display zone without removing the optical storage medium.

Abstract: A one-touch input portable electronic device running one-touch system includes input devices that consist of a built-in keyboard which contains numeral keys 0-9 and a hand-written pad to enable users to execute a preset customized application program and enter a numeric signal by depressing a single key (numeral keys 0-9) and couple with a hand-written pad to enter character and graphic signals so that users can process and control operation in a most convenient, fast and intuitive manner.

Abstract: Disclosed are quaternary ammonium carbonates, bicarbonates, and mixtures thereof as anti-corrosive agents. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying a composition containing one or more quaternary ammonium carbonate or bicarbonate. The disclosure is also directed to anti-corrosive coatings for metal substrates containing these compounds, to metal substrates having these anticorrosive coatings, and to aqueous cleaning solutions containing these compounds.

Abstract: A portable hand-free kit comprised of an amplification set and an ear set within interchangeable talking modes, the amplification set including a front casing and a rear casing buckled to each other, a PCB locked between both casings adapted to a mobile hand-set; a conduction circuit laid on the PCB adapted with a microphone, a speaker, a rechargeable battery and a switch to shuttle between two conversation modes; and the amplification set being buckled to the ear set allowing conversation in the amplification talking mode or switch to the ear set talking mode if privacy is desired.

Abstract: An improved filtering device for an aquarium tank, particularly a filtering device in which a plurality of "U" notches are formed at equal distance in the rim of the cup, the arc section formed by two notches has a lateral rib and the circular connecting rings in the lower portion of the cup allow the cups of the filtering device to be connected easily, the cup can also be rotated freely after connecting. In addition, the suction tube with the impeller, the filtering cotton and the carbon dioxide guide tube as well as the submerged motor combine to function so that carbon dioxide can be dissolved completely in water. Moreover, more oxygen can be generated inside the aquarium tank for healthier fish and plants, the filtered water through the filtering device according to the present invention becomes pure, crystal clear with a whirling and bubbling action.

Abstract: An improved filtering device for aquarium tanks and artificial ponds mainly comprises a water injector which is made up of a top cover plate and a water injector base, a multi-layered filtering member and an external shield cup which is used to contain the filtering member with appropriate space wherein the edge of the top cover plate is made to be a thick edge which has an annular slot for an "O" shaped seal washer to be placed on. When the top cover plate and the external shield cup are put together, the thick edge is covered up inside the external shield cup, allowing the "O" shaped seal washer to seal off the internal rim of the external shield cup.

Abstract: A general purpose register including two input ports and two output ports, each port being addressed by an independent addressing circuit. The general purpose register includes a number of internal registers, and the provision of four independent addresses enables data to be written into two internal registers while data is being read out of two internal registers. The general purpose register also includes circuitry for transferring data from the input ports directly to the output ports without entering the data into the internal registers. Interchanging of bytes of data input words is also accomplished by the general purpose register. The internal registers, the four independent addressing circuits, the data transferring circuitry and additional undedicated circuitry are integrated into a single chip.
